Filling opioid prescriptions akin to a Sisyphean task
Pain management is a huge part of how we in palliative care help patients – and most of the time, I think we do it well, but in the regulatory environment of the opioid epidemic,
A patient – let’s call her Joan – calls me in distress. She is a 62-year-old woman with widespread metastatic breast cancer. Her pain is mainly due to bone metastases, but she also has discomfort due to the cancer’s invasion of the thin membranes that line her lungs and abdomen.
She was started on a combination opioid and acetaminophen tablet about 2 months ago by her oncologist, but is now requiring it around the clock, nearing the ceiling dose for this particular medication.
Given that her pain is escalating, Joan and I discuss starting a long-acting opioid to better manage the peak and trough effect of short-acting opioids, which can make a patient feel that the pain is relieved only for a few hours at a time, with sharp spikes throughout the day that mandate the next dose of short-acting opioid. This tethers the patient to the clock, having to take as many as six or eight doses of medication per day, and can be very disruptive to daily life.
I send an e-prescription for the same opioid Joan’s currently taking, but in a long-acting format that will slow-release over 8-10 hours, relieving her of the need to take a medication every 3-4 hours. I have learned over the years that nearly every long-acting opioid automatically generates a prior authorization request from the patient’s insurance company and so I immediately email our prior authorization team to submit to Joan’s insurance right away to avoid this extra delay.
Our prior authorization team is exceptionally responsive and submits these requests with urgency every time – they understand that cancer pain is a serious problem and we can’t wait 5 business days for answers. They are typically able to obtain an approved prior authorization for nearly every long-acting opioid I write within 24-48 hours.
But here’s where things go sideways.
First, the insurance company denies the prior authorization request, demanding that I revise the prescription from the long-acting version of the opioid she is currently taking to a cheaper, older opioid that she’s never tried before. In other words, they won’t cover the drug I requested without Joan first trying a completely different drug and failing it. This only makes sense for the insurance company’s bottom line – it makes no clinical sense at all. Why would I try a novel compound that Joan’s never had and one to which I have no idea how she’ll respond when I could keep her on the same compound knowing that she tolerates it just fine?
Past experience tells me insurance companies rarely budge on this, and appealing the decision would just introduce even more delay of care, so I begrudgingly change the prescription and send it again to the pharmacy. I message Joan to let her know that her insurance won’t cover my drug of choice and that we have to try this older one first.
A few hours later, Joan sends me a message: “My pharmacy says it’s going to take A WEEK to get the long-acting medicine!”
In the meantime, Joan has been using her short-acting opioid faster than anticipated because of her escalating pain – so she’s now running low on that as well.
I write for more of her short-acting opioid and e-script it to her pharmacy.
Within a few hours, we get another automatic response from her insurance that we’re going to need a prior authorization for additional short-acting opioid because she’s exceeded “quantity limitations,” which as far as I can tell is a completely arbitrary number not based on clinical evidence.
The prior auth team jumps on it and submits to override the quantity limit – successfully – and sends the override code to her pharmacy to reprocess the prescription.
But now the pharmacist tells Joan that they won’t fill the Rx anyway because it’s “too early.” They tell her that “state laws” prevent them from filling the scrip.
Is this true? I have no idea. I’m not an expert on California pharmacy law. All I know is that my patient is in pain and something needs to happen quickly.
I write for a second short-acting opioid – again a completely different compound. Ironically, this Rx goes through instantly without need for prior authorization. But now Joan has to switch to another new drug for no good medical reason.
If you’re still with me this far into the weeds, I’m grateful. In all it took a combined 4 hours of work (between myself and the prior auth team) to get two opioid Rx’s filled – and these were completely different medications than the ones I originally wrote for. I also had to move her prescriptions to the hospital’s pharmacy (another inconvenience for Joan and her family) so that she could get the medications in a timely manner. All this work to ensure that a single patient had adequate and timely pain relief and to prevent her from having to make an unnecessary visit to the emergency department for pain crisis.
This is just a regular day in outpatient palliative care in the era of the opioid epidemic.
The epidemic has caused tremendous pain and suffering for millions of people over the past 2 decades – namely those lost to opioid overdoses and their loved ones. And for the most part, tightening access to opioids for routine aches and pains among a relatively healthy population is not wrong, in my opinion, as long as those restrictions are based in good faith on robust evidence.
But the hidden cost of the Centers for Disease Control and Prevention’s 2016 opioid prescribing guidelines for nonmalignant pain, as well as the flurry of restrictive state laws they generated, is felt every day by patients with serious illness even though the guidelines were never meant to affect them. Patients with active cancer, receiving palliative care services, or at the end of life, were supposed to be exempted from these guidelines since good evidence supports the use of opioids in these populations.
Instead of preserving access to desperately needed pain medicine for those suffering with serious illness, states and insurers have aggressively sought to gatekeep opioids from everyone, resulting in stigma, delays, and needless suffering.
Several recent studies have revealed the effects of this gatekeeping on patients with cancer.
A qualitative study with 26 advanced cancer patients described the demoralization and stigma many patients felt when taking opioids, which they directly tied to media messaging around the opioid epidemic. Even when they reluctantly agreed to take opioids to treat cancer-related pain, there were systemic impediments to achieving adequate pain relief – similar to my experience with Joan – that were directly caused by insurance and pharmacy constraints.
Those of us who care for oncology patients also appear to be undertreating cancer-related pain. Another recent study that found the amount of opioid medications prescribed to an advanced cancer patient near the end of life dropped by 38% between 2007 and 2017. The authors suggest that a direct consequence of this decline in appropriate opioid prescribing is an observed 50% rise in emergency department visits over the same time period by cancer patients for pain-related reasons.
This makes sense – if patients aren’t routinely prescribed the opioids they need to manage their cancer-related pain; or, if the stigma against using opioids is so harsh that it causes patients to shun opioids; or, if there are so many system barriers in place to prevent patients from obtaining opioids in a timely manner – then patients’ pain will crescendo, leaving them with little alternative but to head to the emergency department.
This undertreatment is corroborated by another study that examined data from the Centers for Medicare & Medicaid Services Part D prescriber database between 2013 and 2017, finding that both oncologists and nononcologists prescribed about 21% fewer opioids to Medicare beneficiaries during that time, compared with the period prior to 2013.
Interestingly, the researchers also found that opioid prescribing by palliative care providers increased by 15% over the same period. On a positive note, this suggests the presence of a growing outpatient palliative care workforce. But it may also reflect growing unease among oncologists with the perceived liability for prescribing opioids and a desire to ask other specialists to take on this liability. At the same time, it may reflect the very real and ever-increasing administrative burden associated with prescribing opioids and the fact that busy oncologists may not have time to spend on this aspect of cancer care. Thus, as palliative care clinicians become more visible and numerous in the outpatient arena, oncologists may increasingly ask palliative care clinicians like myself to take this on.
The problem with this is that merely handing off the administrative burden to another clinician doesn’t address the underlying problem. Anecdotal evidence suggests (and my own experiences corroborate) this administrative burden can cause real harm. A survey of 1,000 physicians conducted by the American Medical Association in 2021 found that 93% of respondents reported a delay in patient care due to prior authorization burden and 34% of respondents reported that their patients had suffered a “serious adverse event” due to prior authorization requirements.
The CDC recently announced it will take steps to revise the 2016 opioid prescribing guidelines for chronic pain after hearing from members of the medical community as well as patients living with chronic pain about the harsh, unintended consequences of the guidelines. I can only hope that insurance companies will follow suit, revising their opioid prior authorization requirements to finally come into alignment with the rational, safe use of opioids in patients with advanced cancer. It’s too bad that any improvement in the future will be too late for the millions of patients who have suffered irreversible iatrogenic harms due to delays in achieving adequate pain relief.

Global data suggest rising CLL incidence since 1990
Either way, “to our best knowledge, this study is the first study to provide a comprehensive description of the epidemiology and global burden of CLL worldwide,” the authors reported in BioMedical Engineering Online.
The findings are an evaluation of data from the 2019 Global Burden of Disease study, which includes epidemiological data on 369 diseases in 204 nations and territories around the world.
According to the analysis, the age-standardized incidence rate of CLL rose globally over the last 3 decades, from 0.76 per 100,000 persons in 1990 to 1.34 per 100,000 in 2019, for an estimated annual percentage change of 1.86%.
While increases were observed across all economic levels, the highest increases were observed in regions with the highest social determinant index. Notably, the fastest rise was observed in middle-income regions.
“What cannot be ignored is the rapid growth of the disease burden in middle [social determinant index] regions, which potentially indicated an underestimated incidence and mortality in underdeveloped countries,” write the authors, led by senior author Huafeng Wang, MD, of the department of hematology, The First Affiliated Hospital, Zhejiang University, Hangzhou, China.
The highest annual age-standardized incidence rates in 2019 occurred in western Europe, high-income areas of North America and central Europe, while the fastest increase in the incidence of CLL occurred in east Asia, central Europe, and Andean Latin America, according to the study.
Mortality rates
The age-standardized death rate from CLL also increased globally, from 0.40 per 100,000 persons in 1990 to 0.58 per 100,000 in 2019, for an estimated annual percentage change of 1.17.
The increases in death rates were observed across all income regions over the study period, with the highest age-standardized death rate in 2019, consistent with incidence rates, occurring in the highest-income regions, specifically in central Europe, western Europe, and high-income North America.
The geographic trends were similar in terms of disability-adjusted life-years, which increased globally from 9.20 per 100,000 persons in 1990 to 12.26 per 100,000 in 2019, for an estimated annual percentage change of 0.92%.
The authors noted that the geographic variation of CLL is consistent with research suggesting that White ancestry is a risk factor for this leukemia. And while the incidence of CLL is generally low in the 22 nations of the Arab League, the burden of disease is high in Israel.
Age and gender
The study shows that, during the past 30 years in general, CLL was more common among males, with some regional differences. For instance, in contrast to global trends, females in low-income regions accounted for the majority of incidence and mortality.
The majority of CLL cases occurred in people over the age of 50, which is consistent with known patterns of CLL occurring in older patients. Of note, the majority of cases between the ages of 50 and 69 were in low-income regions, while more than half of the incidence cases in higher-income regions were among those over the age of 70.
Risk factors
Key risk factors that may to be linked to CLL-related mortality and disability include high body mass index, occupational exposure to benzene and formaldehyde, and smoking, which was the strongest risk factor, the authors reported.
Obesity has previously been linked with an increased risk of lymphohematopoietic cancers in general and with poorer responses to treatment and reduced progression-free survival in CLL, in particular.
While the database otherwise provided only limited insights into potential CLL risk factors, “among the factors [the database] provided, the risk of benzene and formaldehyde exposure should be paid attention to,” Dr. Wang said in an interview.
“Different from other risk factors, emerging evidence has clearly pointed out the close relationship between benzene and formaldehyde exposure and hematological malignancies,” he explained. “With globalization, a large number of factories moved to less developed regions. The problem of occupational toxic exposure needs to be addressed.”
In general, the trends in the current study are consistent with previous research showing that, while there was a significant global decrease in leukemia incidence between 1990 and 2017, the incidence rates of CLL as well as acute myeloid leukemia (AML) significantly increased in most countries during that period.
“The age-standardized incidence rate of AML has steadily increased over the past 30 years, but not as rapidly as CLL,” Dr. Wang said.
He added that an encouraging sign is the “significant decline” in the age-standardized rate of chronic myeloid leukemia seen with the advent of tyrosine kinase inhibitors (TKIs).
“Perhaps for CLL, the emergence of epoch-making therapies like TKIs will also contribute to the reduction of disease burden [with that disease],” he said.
Surveillance bias?
The authors note a key caveat that the lower rates observed in low-income regions could be related to underreporting and lower screening of cancers in those regions. However, commenting on the study, Robert Peter Gale, MD, PhD, suggested that, conversely, the trends may represent a surveillance bias, reflecting an increased detection of CLL.
In fact, “it is most unlikely the incidence of CLL is really increasing,” Dr. Gale, visiting professor of hematology at the Hematology Research Centre, department of immunology and inflammation, Imperial College London, said in an interview.
“More than one-half of people with CLL have no signs or symptoms, and the diagnosis is made when they have a blood test done for unrelated reasons,” such as in the process of qualifying for life or medical insurance or for a new job, he explained. “The more testing you do, the more cases you will detect.”
Dr. Gale pointed out that research his team has conducted in China also showed an increasing incidence of CLL. However, “on closer study, we found about two-thirds of cases were incidental, namely cases detected under circumstances [such as blood testing for a job].”
Shen-Miao Yang, MD, first author of that study, agreed and noted that improved treatment with drugs such as Bruton kinase inhibitors also can have the effect of increasing incidence – by extending lives.
“More patients are diagnosed, [and] receive the new agent, and their longer survival contributes to the increased burden of CLL,” Dr. Yang of People’s Hospital of Peking University, Peking University Institute of Hematology, Beijing, said in an interview.
Furthermore, “advanced techniques such as flow cytometry and fluorescence in situ hybridization are routinely used for the diagnosis and prognosis of CLL patients – that also increases the CLL burden.”
Dr. Yang had no disclosures to report. Dr. Gale disclosed that he is a consultant to BeiGene, Fusion Pharma, La Jolla NanoMedical, MingSight Pharmaceuticals, CStone Pharmaceuticals, NexImmune, and Prolacta Bioscience; an adviser to Antengene Biotech; medical director of FFF Enterprises; a partner of AZCA; member of the board of directors of the Russian Foundation for Cancer Research Support; and on the scientific advisory board of StemRad.
Either way, “to our best knowledge, this study is the first study to provide a comprehensive description of the epidemiology and global burden of CLL worldwide,” the authors reported in BioMedical Engineering Online.

According to the analysis, the age-standardized incidence rate of CLL rose globally over the last 3 decades, from 0.76 per 100,000 persons in 1990 to 1.34 per 100,000 in 2019, for an estimated annual percentage change of 1.86%.
While increases were observed across all economic levels, the highest increases were observed in regions with the highest social determinant index. Notably, the fastest rise was observed in middle-income regions.
“What cannot be ignored is the rapid growth of the disease burden in middle [social determinant index] regions, which potentially indicated an underestimated incidence and mortality in underdeveloped countries,” write the authors, led by senior author Huafeng Wang, MD, of the department of hematology, The First Affiliated Hospital, Zhejiang University, Hangzhou, China.
The highest annual age-standardized incidence rates in 2019 occurred in western Europe, high-income areas of North America and central Europe, while the fastest increase in the incidence of CLL occurred in east Asia, central Europe, and Andean Latin America, according to the study.
Mortality rates
The age-standardized death rate from CLL also increased globally, from 0.40 per 100,000 persons in 1990 to 0.58 per 100,000 in 2019, for an estimated annual percentage change of 1.17.
The increases in death rates were observed across all income regions over the study period, with the highest age-standardized death rate in 2019, consistent with incidence rates, occurring in the highest-income regions, specifically in central Europe, western Europe, and high-income North America.
The geographic trends were similar in terms of disability-adjusted life-years, which increased globally from 9.20 per 100,000 persons in 1990 to 12.26 per 100,000 in 2019, for an estimated annual percentage change of 0.92%.
The authors noted that the geographic variation of CLL is consistent with research suggesting that White ancestry is a risk factor for this leukemia. And while the incidence of CLL is generally low in the 22 nations of the Arab League, the burden of disease is high in Israel.
Age and gender
The study shows that, during the past 30 years in general, CLL was more common among males, with some regional differences. For instance, in contrast to global trends, females in low-income regions accounted for the majority of incidence and mortality.
The majority of CLL cases occurred in people over the age of 50, which is consistent with known patterns of CLL occurring in older patients. Of note, the majority of cases between the ages of 50 and 69 were in low-income regions, while more than half of the incidence cases in higher-income regions were among those over the age of 70.
Risk factors
Key risk factors that may to be linked to CLL-related mortality and disability include high body mass index, occupational exposure to benzene and formaldehyde, and smoking, which was the strongest risk factor, the authors reported.
Obesity has previously been linked with an increased risk of lymphohematopoietic cancers in general and with poorer responses to treatment and reduced progression-free survival in CLL, in particular.
While the database otherwise provided only limited insights into potential CLL risk factors, “among the factors [the database] provided, the risk of benzene and formaldehyde exposure should be paid attention to,” Dr. Wang said in an interview.
“Different from other risk factors, emerging evidence has clearly pointed out the close relationship between benzene and formaldehyde exposure and hematological malignancies,” he explained. “With globalization, a large number of factories moved to less developed regions. The problem of occupational toxic exposure needs to be addressed.”
In general, the trends in the current study are consistent with previous research showing that, while there was a significant global decrease in leukemia incidence between 1990 and 2017, the incidence rates of CLL as well as acute myeloid leukemia (AML) significantly increased in most countries during that period.
“The age-standardized incidence rate of AML has steadily increased over the past 30 years, but not as rapidly as CLL,” Dr. Wang said.
He added that an encouraging sign is the “significant decline” in the age-standardized rate of chronic myeloid leukemia seen with the advent of tyrosine kinase inhibitors (TKIs).
“Perhaps for CLL, the emergence of epoch-making therapies like TKIs will also contribute to the reduction of disease burden [with that disease],” he said.
Surveillance bias?
The authors note a key caveat that the lower rates observed in low-income regions could be related to underreporting and lower screening of cancers in those regions. However, commenting on the study, Robert Peter Gale, MD, PhD, suggested that, conversely, the trends may represent a surveillance bias, reflecting an increased detection of CLL.
In fact, “it is most unlikely the incidence of CLL is really increasing,” Dr. Gale, visiting professor of hematology at the Hematology Research Centre, department of immunology and inflammation, Imperial College London, said in an interview.
“More than one-half of people with CLL have no signs or symptoms, and the diagnosis is made when they have a blood test done for unrelated reasons,” such as in the process of qualifying for life or medical insurance or for a new job, he explained. “The more testing you do, the more cases you will detect.”
Dr. Gale pointed out that research his team has conducted in China also showed an increasing incidence of CLL. However, “on closer study, we found about two-thirds of cases were incidental, namely cases detected under circumstances [such as blood testing for a job].”
Shen-Miao Yang, MD, first author of that study, agreed and noted that improved treatment with drugs such as Bruton kinase inhibitors also can have the effect of increasing incidence – by extending lives.
“More patients are diagnosed, [and] receive the new agent, and their longer survival contributes to the increased burden of CLL,” Dr. Yang of People’s Hospital of Peking University, Peking University Institute of Hematology, Beijing, said in an interview.
Furthermore, “advanced techniques such as flow cytometry and fluorescence in situ hybridization are routinely used for the diagnosis and prognosis of CLL patients – that also increases the CLL burden.”
Dr. Yang had no disclosures to report. Dr. Gale disclosed that he is a consultant to BeiGene, Fusion Pharma, La Jolla NanoMedical, MingSight Pharmaceuticals, CStone Pharmaceuticals, NexImmune, and Prolacta Bioscience; an adviser to Antengene Biotech; medical director of FFF Enterprises; a partner of AZCA; member of the board of directors of the Russian Foundation for Cancer Research Support; and on the scientific advisory board of StemRad.

Women at higher risk of serious adverse events from cancer therapy
and this is seen with chemotherapy, targeted agents, and especially with immunotherapy.
The finding comes from a review of more than 23,000 participants across 202 trials of various cancers (excluding sex-related cancers) that has been conducted over the past 40 years.
The investigators found a 34% increased risk of severe AEs among women, compared with men, climbing to a 49% higher risk with immunotherapy.
Women had a substantially greater risk of severe symptomatic AEs, including with immune checkpoint inhibitors and targeted tyrosine kinase inhibitors, and were more likely to experience severe hematologic AEs with chemotherapy and immunotherapy.
The particularly large sex differences with immunotherapy suggest “that studying AEs from these agents is a priority,” the investigators comment.
The article was published online on Feb. 4 in the Journal of Clinical Oncology.
“It has been understood that women have more toxicity from chemotherapy than men, but almost no research has aimed to understand whether that pattern held for novel treatments like immunotherapy or targeted therapies. We found similar large differences, especially for immune treatments,” said lead investigator Joseph Unger, PhD, a biostatistician and health services researcher at the Fred Hutchinson Cancer Research Center, Seattle, in an institutional press release.
A “better understanding of the nature of the underlying mechanisms could potentially lead to interventions or delivery modifications to reduce toxicity in women,” the investigators comment in their article.
Among a sea of possible explanations for the finding, there could be differences in how men and women metabolize cancer therapies or differences in how they perceive symptoms. Women may also receive relatively higher doses because of their body size or have higher adherence to treatment.
Whatever the case, as cancer treatment becomes increasingly individualized, “sex may be an important consideration,” Dr. Unger said.
Study details
The study involved 8,838 women and 14,458 men across the trials, which were phase 2 or 3 investigations conducted by the SWOG Cancer Research Network from 1980 to 2019. Trials including sex-related cancers were excluded. In the trials included in the review, the most common cancers were gastrointestinal and lung, followed by leukemia.
Seventy-five percent of the subjects received chemotherapy, and the rest received either targeted therapy or immunotherapy.
Two-thirds of the subjects had at least one grade 3 or higher AE; women had a 25% higher risk than men of having AEs of grade 5 or higher.
After adjusting for age, race, disease prognosis, and other factors, women were at increased risk of severe symptomatic AEs, such as nausea and pain, across all treatment lines and especially with immunotherapy, for which reports of symptomatic AEs were 66% higher.
Women also had a higher risk of symptomatic gastrointestinal AEs with all three treatments and a higher risk of sleep-related AEs with chemotherapy and immunotherapy, which “could be a function of hormonal effects interacting with cancer treatment,” the investigators said.
As for readily measurable AEs, women were at higher risk than men for objective hematologic AEs with chemotherapy, immunotherapy, and targeted therapy. There were no statistically significant sex differences in the risk of nonhematologic objective AEs.
The team notes that increased toxicity among women has been associated with improved survival, which may give AEs more time to develop. Higher rates of AEs might also signal increased delivery or efficacy of cancer treatments.
However, a previous study found that men may have a better response to immunotherapy than women. Immune checkpoint inhibitors were twice as effective as standard cancer therapies in the treatment of men with advanced solid tumors compared to their female counterparts, concluded a team that carried out a meta-analysis of 20 randomized controlled trials involving more than 11,351 patients.
The study was funded by the National Cancer Institute and others. Dr. Unger has disclosed no relevant financial relationships. Several coauthors have reported ties to a handful of companies, including Johnson & Johnson and Seattle Genetics. One is an employee of AIM Specialty Health.

“I didn’t want to meet you.” Dispelling myths about palliative care
The names of health care professionals and patients cited within the dialogue text have been changed to protect their privacy.
but over the years I have come to realize that she was right – most people, including many within health care, don’t have a good appreciation of what palliative care is or how it can help patients and health care teams.
A recent national survey about cancer-related health information found that of more than 1,000 surveyed Americans, less than 30% professed any knowledge of palliative care. Of those who had some knowledge of palliative care, around 30% believed palliative care was synonymous with hospice.1 Another 15% believed that a patient would have to give up cancer-directed treatments to receive palliative care.1
It’s not giving up
This persistent belief that palliative care is equivalent to hospice, or is tantamount to “giving up,” is one of the most commonly held myths I encounter in everyday practice.
I knock on the exam door and walk in.
A small, trim woman in her late 50s is sitting in a chair, arms folded across her chest, face drawn in.
“Hi,” I start. “I’m Sarah, the palliative care nurse practitioner who works in this clinic. I work closely with Dr. Smith.”
Dr. Smith is the patient’s oncologist.
“I really didn’t want to meet you,” she says in a quiet voice, her eyes large with concern.
I don’t take it personally. Few patients really want to be in the position of needing to meet the palliative care team.
“I looked up palliative care on Google and saw the word hospice.”
“Yeah,” I say. “I hear that a lot. Well, I can reassure you that this isn’t hospice.
In this clinic, our focus is on your cancer symptoms, your treatment side effects, and your quality of life.”
She looks visibly relieved. “Quality of life,” she echoes. “I need more of that.”
“OK,” I say. “So, tell me what you’re struggling with the most right now.”
That’s how many palliative care visits start. I actually prefer if patients haven’t heard of palliative care because it allows me to frame it for them, rather than having to start by addressing a myth or a prior negative experience. Even when patients haven’t had a negative experience with palliative care per se, typically, if they’ve interacted with palliative care in the past, it’s usually because someone they loved died in a hospital setting and it is the memory of that terrible loss that becomes synonymous with their recollection of palliative care.
Many patients I meet have never seen another outpatient palliative care practitioner – and this makes sense – we are still too few and far between. Most established palliative care teams are hospital based and many patients seen in the community do not have easy access to palliative care teams where they receive oncologic care.2 As an embedded practitioner, I see patients in the same exam rooms and infusion centers where they receive their cancer therapies, so I’m effectively woven into the fabric of their oncology experience. Just being there in the cancer center allows me to be in the right place at the right time for the right patients and their care teams.
More than pain management
Another myth I tend to dispel a lot is that palliative care is just a euphemism for “pain management.” I have seen this less lately, but still occasionally in the chart I’ll see documented in a note, “patient is seeing palliative/pain management,” when a patient is seeing me or one of my colleagues. Unfortunately, when providers have limited or outdated views of what palliative care is or the value it brings to patient-centered cancer care, referrals to palliative care tend to be delayed.3
“I really think Ms. Lopez could benefit from seeing palliative care,” an oncology nurse practitioner says to an oncologist.
I’m standing nearby, about to see another patient in one of the exam rooms in our clinic.
“But I don’t think she’s ready. And besides, she doesn’t have any pain,” he says.
He turns to me quizzically. “What do you think?”
“Tell me about the patient,” I ask, taking a few steps in their direction.
“Well, she’s a 64-year-old woman with metastatic cancer.
She has a really poor appetite and is losing some weight.
Seems a bit down, kind of pessimistic about things.
Her scan showed some new growth, so guess I’m not surprised by that.”
“I might be able to help her with the appetite and the mood changes.
I can at least talk with her and see where she’s at,” I offer.
“Alright,” he says. “We’ll put the palliative referral in.”
He hesitates. “But are you sure you want to see her?
She doesn’t have any pain.” He sounds skeptical.
“Yeah, I mean, it sounds like she has symptoms that are bothering her, so I’d be happy to see her. She sounds completely appropriate for palliative care.”
I hear this assumption a lot – that palliative care is somehow equivalent to pain management and that unless a patient’s pain is severe, it’s not worth referring the patient to palliative care. Don’t get me wrong – we do a lot of pain management, but at its heart, palliative care is an interdisciplinary specialty focused on improving or maintaining quality of life for people with serious illness. Because the goal is so broad, care can take many shapes.4
In addition to pain, palliative care clinicians commonly treat nausea, shortness of breath, constipation or diarrhea, poor appetite, fatigue, anxiety, depression, and insomnia.
Palliative care is more than medical or nursing care
A related misconception about palliative care held by many lay people and health care workers alike is that palliative care is primarily medical or nursing care focused mostly on alleviating physical symptoms such as pain or nausea. This couldn’t be further from the truth.
We’ve been talking for a while.
Ms. Lopez tells me about her struggles to maintain her weight while undergoing chemotherapy. She has low-grade nausea that is impacting her ability and desire to eat more and didn’t think that her weight loss was severe enough to warrant taking medication.
We talk about how she may be able to use antinausea medication sparingly to alleviate nausea while also limiting side effects from the medications—which was a big concern for her.
I ask her what else is bothering her.
She tells me that she has always been a strong Catholic and even when life has gotten tough, her faith was never shaken – until now.
She is struggling to understand why she ended up with metastatic cancer at such a relatively young age—why would God do this to her?
She had plans for retirement that have since evaporated in the face of a foreshortened life.
Why did this happen to her of all people? She was completely healthy until her diagnosis.
Her face is wet with tears.
We talk a little about how a diagnosis like this can change so much of a person’s life and identity. I try to validate her experience. She’s clearly suffering from a sense that her life is not what she expected, and she is struggling to integrate how her future looks at this point.
I ask her what conversations with her priest have been like.
At this point you may be wondering where this conversation is going. Why are we talking about Ms. Lopez’s religion? Palliative care is best delivered through high functioning interdisciplinary teams that can include other supportive people in a patient’s life. We work in concert to try to bring comfort to a patient and their family.4 That support network can include nurses, physicians, social workers, and chaplains. In this case, Ms. Lopez had not yet reached out to her priest. She hasn’t had the time or energy to contact her priest given her symptoms.
“Can I contact your priest for you?
Maybe he can visit or call and chat with you?”
She nods and wipes tears away.
“That would be really nice,” she says. “I’d love it if he could pray with me.”
A few hours after the visit, I call Ms. Lopez’s priest.
I ask him to reach out to her and about her request for prayer.
He says he’s been thinking about her and that her presence has been missed at weekly Mass. He thanks me for the call and says he’ll call her tomorrow.
I say my own small prayer for Ms. Lopez and head home, the day’s work completed.
Sarah D'Ambruoso was born and raised in Maine. She completed her undergraduate and graduate nursing education at New York University and UCLA, respectively, and currently works as a palliative care nurse practitioner in an oncology clinic in Los Angeles.

but over the years I have come to realize that she was right – most people, including many within health care, don’t have a good appreciation of what palliative care is or how it can help patients and health care teams.
A recent national survey about cancer-related health information found that of more than 1,000 surveyed Americans, less than 30% professed any knowledge of palliative care. Of those who had some knowledge of palliative care, around 30% believed palliative care was synonymous with hospice.1 Another 15% believed that a patient would have to give up cancer-directed treatments to receive palliative care.1
It’s not giving up
This persistent belief that palliative care is equivalent to hospice, or is tantamount to “giving up,” is one of the most commonly held myths I encounter in everyday practice.
I knock on the exam door and walk in.
A small, trim woman in her late 50s is sitting in a chair, arms folded across her chest, face drawn in.
“Hi,” I start. “I’m Sarah, the palliative care nurse practitioner who works in this clinic. I work closely with Dr. Smith.”
Dr. Smith is the patient’s oncologist.
“I really didn’t want to meet you,” she says in a quiet voice, her eyes large with concern.
I don’t take it personally. Few patients really want to be in the position of needing to meet the palliative care team.
“I looked up palliative care on Google and saw the word hospice.”
“Yeah,” I say. “I hear that a lot. Well, I can reassure you that this isn’t hospice.
In this clinic, our focus is on your cancer symptoms, your treatment side effects, and your quality of life.”
She looks visibly relieved. “Quality of life,” she echoes. “I need more of that.”
“OK,” I say. “So, tell me what you’re struggling with the most right now.”
That’s how many palliative care visits start. I actually prefer if patients haven’t heard of palliative care because it allows me to frame it for them, rather than having to start by addressing a myth or a prior negative experience. Even when patients haven’t had a negative experience with palliative care per se, typically, if they’ve interacted with palliative care in the past, it’s usually because someone they loved died in a hospital setting and it is the memory of that terrible loss that becomes synonymous with their recollection of palliative care.
Many patients I meet have never seen another outpatient palliative care practitioner – and this makes sense – we are still too few and far between. Most established palliative care teams are hospital based and many patients seen in the community do not have easy access to palliative care teams where they receive oncologic care.2 As an embedded practitioner, I see patients in the same exam rooms and infusion centers where they receive their cancer therapies, so I’m effectively woven into the fabric of their oncology experience. Just being there in the cancer center allows me to be in the right place at the right time for the right patients and their care teams.
More than pain management
Another myth I tend to dispel a lot is that palliative care is just a euphemism for “pain management.” I have seen this less lately, but still occasionally in the chart I’ll see documented in a note, “patient is seeing palliative/pain management,” when a patient is seeing me or one of my colleagues. Unfortunately, when providers have limited or outdated views of what palliative care is or the value it brings to patient-centered cancer care, referrals to palliative care tend to be delayed.3
“I really think Ms. Lopez could benefit from seeing palliative care,” an oncology nurse practitioner says to an oncologist.
I’m standing nearby, about to see another patient in one of the exam rooms in our clinic.
“But I don’t think she’s ready. And besides, she doesn’t have any pain,” he says.
He turns to me quizzically. “What do you think?”
“Tell me about the patient,” I ask, taking a few steps in their direction.
“Well, she’s a 64-year-old woman with metastatic cancer.
She has a really poor appetite and is losing some weight.
Seems a bit down, kind of pessimistic about things.
Her scan showed some new growth, so guess I’m not surprised by that.”
“I might be able to help her with the appetite and the mood changes.
I can at least talk with her and see where she’s at,” I offer.
“Alright,” he says. “We’ll put the palliative referral in.”
He hesitates. “But are you sure you want to see her?
She doesn’t have any pain.” He sounds skeptical.
“Yeah, I mean, it sounds like she has symptoms that are bothering her, so I’d be happy to see her. She sounds completely appropriate for palliative care.”
I hear this assumption a lot – that palliative care is somehow equivalent to pain management and that unless a patient’s pain is severe, it’s not worth referring the patient to palliative care. Don’t get me wrong – we do a lot of pain management, but at its heart, palliative care is an interdisciplinary specialty focused on improving or maintaining quality of life for people with serious illness. Because the goal is so broad, care can take many shapes.4
In addition to pain, palliative care clinicians commonly treat nausea, shortness of breath, constipation or diarrhea, poor appetite, fatigue, anxiety, depression, and insomnia.
Palliative care is more than medical or nursing care
A related misconception about palliative care held by many lay people and health care workers alike is that palliative care is primarily medical or nursing care focused mostly on alleviating physical symptoms such as pain or nausea. This couldn’t be further from the truth.
We’ve been talking for a while.
Ms. Lopez tells me about her struggles to maintain her weight while undergoing chemotherapy. She has low-grade nausea that is impacting her ability and desire to eat more and didn’t think that her weight loss was severe enough to warrant taking medication.
We talk about how she may be able to use antinausea medication sparingly to alleviate nausea while also limiting side effects from the medications—which was a big concern for her.
I ask her what else is bothering her.
She tells me that she has always been a strong Catholic and even when life has gotten tough, her faith was never shaken – until now.
She is struggling to understand why she ended up with metastatic cancer at such a relatively young age—why would God do this to her?
She had plans for retirement that have since evaporated in the face of a foreshortened life.
Why did this happen to her of all people? She was completely healthy until her diagnosis.
Her face is wet with tears.
We talk a little about how a diagnosis like this can change so much of a person’s life and identity. I try to validate her experience. She’s clearly suffering from a sense that her life is not what she expected, and she is struggling to integrate how her future looks at this point.
I ask her what conversations with her priest have been like.
At this point you may be wondering where this conversation is going. Why are we talking about Ms. Lopez’s religion? Palliative care is best delivered through high functioning interdisciplinary teams that can include other supportive people in a patient’s life. We work in concert to try to bring comfort to a patient and their family.4 That support network can include nurses, physicians, social workers, and chaplains. In this case, Ms. Lopez had not yet reached out to her priest. She hasn’t had the time or energy to contact her priest given her symptoms.
“Can I contact your priest for you?
Maybe he can visit or call and chat with you?”
She nods and wipes tears away.
“That would be really nice,” she says. “I’d love it if he could pray with me.”
A few hours after the visit, I call Ms. Lopez’s priest.
I ask him to reach out to her and about her request for prayer.
He says he’s been thinking about her and that her presence has been missed at weekly Mass. He thanks me for the call and says he’ll call her tomorrow.
I say my own small prayer for Ms. Lopez and head home, the day’s work completed.

Severe COVID two times higher for cancer patients
A new systematic review and meta-analysis finds that unvaccinated cancer patients who contracted COVID-19 last year, were more than two times more likely – than people without cancer – to develop a case of COVID-19 so severe it required hospitalization in an intensive care unit.
“Our study provides the most precise measure to date of the effect of COVID-19 in cancer patients,” wrote researchers who were led by Paolo Boffetta, MD, MPH, a specialist in population science with the Stony Brook Cancer Center in New York.
Dr. Boffetta and colleagues also found that patients with hematologic neoplasms had a higher mortality rate from COVID-19 comparable to that of all cancers combined.
Cancer patients have long been considered to be among those patients who are at high risk of developing COVID-19, and if they contract the disease, they are at high risk of having poor outcomes. Other high-risk patients include those with hypertension, diabetes, chronic kidney disease, or COPD, or the elderly. But how high the risk of developing severe COVID-19 disease is for cancer patients hasn’t yet been documented on a wide scale.
The study, which was made available as a preprint on medRxiv on Oct. 23, is based on an analysis of COVID-19 cases that were documented in 35 reviews, meta-analyses, case reports, and studies indexed in PubMed from authors in North America, Europe, and Asia.
In this study, the pooled odds ratio for mortality for all patients with any cancer was 2.32 (95% confidence interval, 1.82-2.94; 24 studies). For ICU admission, the odds ratio was 2.39 (95% CI, 1.90-3.02; I2 0.0%; 5 studies). And, for disease severity or hospitalization, it was 2.08 (95% CI, 1.60-2.72; I2 92.1%; 15 studies). The pooled mortality odds ratio for hematologic neoplasms was 2.14 (95% CI, 1.87-2.44; I2 20.8%; 8 studies).
Their findings, which have not yet been peer reviewed, confirmed the results of a similar analysis from China published as a preprint in May 2020. The analysis included 181,323 patients (23,736 cancer patients) from 26 studies reported an odds ratio of 2.54 (95% CI, 1.47-4.42). “Cancer patients with COVID-19 have an increased likelihood of death compared to non-cancer COVID-19 patients,” Venkatesulu et al. wrote. And a systematic review and meta-analysis of five studies of 2,619 patients published in October 2020 in Medicine also found a significantly higher risk of death from COVID-19 among cancer patients (odds ratio, 2.63; 95% confidence interval, 1.14-6.06; P = .023; I2 = 26.4%).
Fakih et al., writing in the journal Hematology/Oncology and Stem Cell Therapy conducted a meta-analysis early last year finding a threefold increase for admission to the intensive care unit, an almost fourfold increase for a severe SARS-CoV-2 infection, and a fivefold increase for being intubated.
The three studies show that mortality rates were higher early in the pandemic “when diagnosis and treatment for SARS-CoV-2 might have been delayed, resulting in higher death rate,” Boffetta et al. wrote, adding that their analysis showed only a twofold increase most likely because it was a year-long analysis.
“Future studies will be able to better analyze this association for the different subtypes of cancer. Furthermore, they will eventually be able to evaluate whether the difference among vaccinated population is reduced,” Boffetta et al. wrote.
The authors noted several limitations for the study, including the fact that many of the studies included in the analysis did not include sex, age, comorbidities, and therapy. Nor were the authors able to analyze specific cancers other than hematologic neoplasms.
The authors declared no conflicts of interest.

Convenience, not outcomes may drive robot-assisted surgeries
“The problem in minimally invasive surgery, especially in cancer surgery, is that the concept has been flip-flopped,” said Hooman Noorchashm, MD, PhD, a retired cardiothoracic surgeon turned patient advocate. “The main purpose of surgery should be removal of diseased tissue or repair of damaged tissue with adequate safety. The size of the incision on that triage scheme is secondary.”
In 2013, Dr. Noorchashm’s wife, Amy Reed, MD, an anesthesiologist, had a hysterectomy for treatment of severe uterine fibroids. The surgery was performed with a laparoscopic power morcellator, which led to the dissemination of cells from a previously undetected abdominal lesion. She was later diagnosed with stage 4 leiomyosarcoma and died in May 2017.
Dr. Noorchashm said the problem with robotic surgery isn’t the technology itself or how it’s used, but why it’s used in the first place. “Not only was there an extreme level of laxity with respect to the malignant potential of fibroids, but also that the size of the incision supersedes the safety of the procedure.”
The ultimate goal of oncologic surgery is to achieve an en bloc resection with clean surgical margins and removal of the tumor intact, Dr. Noorchashm said. The only scientific way of showing the benefits or therapeutic equivalence of new technology is through noninferiority comparison trials.
Robotic surgery inching toward $14 billion in revenue by 2028
Although robotic surgical technology has been in use since the 1990s, the technology is still considered to be its infancy. The first Food and Drug Administration–approved robotics platform, the da Vinci Surgical System (Intuitive Surgical) was approved by the FDA in 2000. And, now, with its patent expiring in 2022, competitors will be developing and launching new products for abdominal and colorectal surgery, partial knee replacements, cardiovascular procedures, head and neck surgery, and spinal procedures.
Robotic surgery is a rapidly expanding area with new product launches announced daily. In August 2021, the market research firm Grand View Research, reported the surgical robot marketplace is projected to reach $14 billion by 2028, up from $3.6 billion this year.
“This new era of robotic-assisted surgery attracts both surgeons and patients. Robotic surgery has reshaped our surgeries over the last 2 decades, and robots are now used in almost in every surgical field. Still, as surgeons, we continue to look – with great interest – to new robotic companies that may be able to provide better robots in a more cost-effective manner,” wrote urologists Ahmad Almujalhem and Koon Ho Rha in a review published in the journal BJUI Compass.
However, the authors wrote that, although the market is competitive, cost remains an issue, as are competing interests. In addition, many companies are creating replicas of existing technologies instead of focusing on new designs and new technology. “Although the da Vinci system propelled many robots to market, there has been no significant improvement in the console,” they added.
The technology is attractive to both surgeons and patients. “Surgeons are attracted to newer technologies, better vision, and easier learning curves. Patients are also attracted to robotic surgery, as this technology is considered state of the art and is associated with reduced pain and scar size,” the authors wrote.
Outcomes depend on many variables
In terms of outcomes, the literature is mixed. It largely depends on a number of variables from the site of surgery, the type of cancer, technology used, and the surgeon’s skill.
Jung Mogg Kim, MD, PhD, a microbiologist with Hanyang University, Seoul, South Korea, published a systemic review and meta-analysis of 27 clinical reports in PLoS ONE assessing clinical outcomes. They found that robot-assisted laparoscopic surgery did not result in statistically superior outcomes, compared with conventional laparoscopic surgery, except for lower estimated blood loss with robots. Operative time and total complications rates were “significantly more favorable” with conventional laparoscopic procedures.
Thomas E. Ahlering, MD, a robotic prostatectomy specialist at the University of California, Irvine, explained that the success or failure of robot-assisted surgery can be highly dependent on the body site and tumor type.
“The oncologic outcome, as long as the surgeon is up to speed, is not going to be better, but the goal is to be as good,” he said in an interview.
In most cases, Dr. Ahlering said, the goal of surgery is to remove a viable tumor with clean margins while leaving the organ intact. But in prostate surgery, the goal is to remove the entire organ while trying to preserve urinary continence and sexual function.
“One of the biggest benefits of the robot is that we’re able to use it in a laparoscopic environment meaning that we need a pneumoperitoneum [which] dramatically decreases bleeding. In prostate cancer, the area is so highly vascular that bleeding is a major issue,” he said.
The same benefits of reduced bleeding, improved visualization, and precision are also seen with robotic-assisted surgery for renal cancer, he noted.
He also emphasized that positive surgical margins, while less desirable than complete elimination of malignant cells, is not nearly as dire in prostate cancer as it is in surgery for other malignancies, such as soft-tissue sarcomas.
“The majority of cases are never going to recur, and if they do recur they essentially never lead to metastatic disease to bone, much less to prostate cancer–related death. The only thing they can do is slightly increase the PSA [prostate-specific antigen] recurrence,” he said.
Assuming that outcomes are comparable between an open procedure, conventional laparoscopic procedure, or robot-assisted approach, surgeons “will almost all go for the robot. It’s easier on the surgeon and it’s easier on the system,” Dr. Ahlering said.
In skilled hands for select patients, the use of a carefully researched and well-designed surgical assistive device can result in outcomes that are comparable with those seen in open surgical procedures, with robot-assisted surgery offering the possibility of less perioperative bleeding, lower postoperative morbidity, and faster recovery times.
“In our program we have been using robots to perform robotic radical prostatectomy and nephron-sparing surgery – partial nephrectomy and we’re also using them to perform intracorporeal bowel reconstruction and robotic radical cystectomy,” said Ashutosh Tewari, MD, of the Icahn School of Medicine at Mount Sinai, New York.
Robot-assisted surgery can be used “anywhere where you have to be selective, anywhere where you have to be reconstructive, anywhere where [assisted] vision can help, anywhere where the lack of bleeding will be of help to patients, and anywhere where a smaller incision can achieve the same goals,” Dr. Tewari said in an interview. Dr. Tewari’s Mount Sinai colleagues reported at the 2021 American Urological Association annual meeting, robotic-assisted salvage radical and partial nephrectomies were found to be safe and feasible procedures in patients with metachronous kidney tumors. For patients with early invasive cancer (stage pT1), oncologic outcomes with robotic-assisted partial nephrectomy were similar to those of patients who underwent radical surgery. The authors concluded that salvage robotic-assisted partial nephrectomy “can be considered in this group of patients due to the risk of future recurrences and need to preserve renal function.”
The National Comprehensive Cancer Network guideline for prostate cancer, updated in September 2021, states that “laparoscopic and robot-assisted radical prostatectomy are commonly used and are considered comparable to conventional approaches in experienced hands.”
In 2018, researchers in a multinational comparison trial reported that patients with cervical cancer who were randomly assigned to minimally invasive robot-assisted radical hysterectomy had significantly lower rates of both disease-free survival and overall survival than women randomized to open abdominal radical hysterectomy. The study results were published in the New England Journal of Medicine.
The use of robotically assisted surgical (RAS) devices could possibly create a “shielding layer” between the surgical team and patient reducing the risk of infection, according to Ajmal Zemmar, MD, PhD, FMH, a neurosurgeon with the University of Louisville (Ky.) Dr. Zemmar and colleagues recently published a perspective in Nature Machine Intelligence on trends in the use of surgical robots.
“In the operating theatre, robots can place intravascular lines, intubate the patient and manage the airway. The integration of a robot as a shielding layer, physically separating the health care worker and patient, is a powerful tool to combat the omnipresent fear of pathogen contamination and maintain surgical volumes,” Dr. Zemmar and colleagues wrote.
Surgical vs. clinical outcomes
In July 2021, this news organization reported that clinical trials of RAS for nipple-sparing mastectomy procedures were looking primarily at cosmetic or surgical outcomes and were not collecting cancer outcomes and if they were, it was secondary to cosmetic or surgical outcomes.
The FDA followed up by issuing a safety communication in August warning patients and providers that neither the safety nor efficacy of RAS for use in mastectomy procedures or treatment of breast cancer have been established.
“In addition, the FDA is aware of allegations that clinical studies are being conducted using RAS devices to perform mastectomies for the prevention or treatment of cancer without the FDA oversight required for such significant risk studies,” the communication stated.
Dr. Tewari disclosed relationships with various companies. Dr. Noorchashm had no relevant disclosures. Dr. Ahlering disclosed past funding or other considerations from Intuitive Robotics.
“The problem in minimally invasive surgery, especially in cancer surgery, is that the concept has been flip-flopped,” said Hooman Noorchashm, MD, PhD, a retired cardiothoracic surgeon turned patient advocate. “The main purpose of surgery should be removal of diseased tissue or repair of damaged tissue with adequate safety. The size of the incision on that triage scheme is secondary.”
In 2013, Dr. Noorchashm’s wife, Amy Reed, MD, an anesthesiologist, had a hysterectomy for treatment of severe uterine fibroids. The surgery was performed with a laparoscopic power morcellator, which led to the dissemination of cells from a previously undetected abdominal lesion. She was later diagnosed with stage 4 leiomyosarcoma and died in May 2017.
Dr. Noorchashm said the problem with robotic surgery isn’t the technology itself or how it’s used, but why it’s used in the first place. “Not only was there an extreme level of laxity with respect to the malignant potential of fibroids, but also that the size of the incision supersedes the safety of the procedure.”
The ultimate goal of oncologic surgery is to achieve an en bloc resection with clean surgical margins and removal of the tumor intact, Dr. Noorchashm said. The only scientific way of showing the benefits or therapeutic equivalence of new technology is through noninferiority comparison trials.
Robotic surgery inching toward $14 billion in revenue by 2028
Although robotic surgical technology has been in use since the 1990s, the technology is still considered to be its infancy. The first Food and Drug Administration–approved robotics platform, the da Vinci Surgical System (Intuitive Surgical) was approved by the FDA in 2000. And, now, with its patent expiring in 2022, competitors will be developing and launching new products for abdominal and colorectal surgery, partial knee replacements, cardiovascular procedures, head and neck surgery, and spinal procedures.
Robotic surgery is a rapidly expanding area with new product launches announced daily. In August 2021, the market research firm Grand View Research, reported the surgical robot marketplace is projected to reach $14 billion by 2028, up from $3.6 billion this year.
“This new era of robotic-assisted surgery attracts both surgeons and patients. Robotic surgery has reshaped our surgeries over the last 2 decades, and robots are now used in almost in every surgical field. Still, as surgeons, we continue to look – with great interest – to new robotic companies that may be able to provide better robots in a more cost-effective manner,” wrote urologists Ahmad Almujalhem and Koon Ho Rha in a review published in the journal BJUI Compass.
However, the authors wrote that, although the market is competitive, cost remains an issue, as are competing interests. In addition, many companies are creating replicas of existing technologies instead of focusing on new designs and new technology. “Although the da Vinci system propelled many robots to market, there has been no significant improvement in the console,” they added.
The technology is attractive to both surgeons and patients. “Surgeons are attracted to newer technologies, better vision, and easier learning curves. Patients are also attracted to robotic surgery, as this technology is considered state of the art and is associated with reduced pain and scar size,” the authors wrote.

Many patients, doctors unaware of advancements in cancer care
This is the main finding from two studies presented at the 2021 European Society for Medical Oncology Congress.
The survey of patients found that most don’t understand how immunotherapy works, and the survey of doctors found that many working outside of the cancer field are using information on survival that is wildly out of date.
When a patient is first told they have cancer, counseling is usually done by a surgeon or general medical doctor and not an oncologist, said Conleth Murphy, MD, of Bon Secours Hospital Cork, Ireland, and coauthor of the second study.
Noncancer doctors often grossly underestimate patients’ chances of survival, Dr. Murphy’s study found. This suggests that doctors who practice outside of cancer care may be working with the same information they learned in medical school, he said.
“These patients must be spared the traumatic effects of being handed a death sentence that no longer reflects the current reality,” Dr. Murphy said.
After receiving a diagnosis of cancer, “patients often immediately have pressing questions about what it means for their future,” he noted. A common question is: “How long do I have left?”
Nononcologists should refrain from answering patients’ questions with numbers, Dr. Murphy said.
Family doctors are likely to be influenced by the experience they have had with specific cancer patients in their practice, said Cyril Bonin, MD, a general practitioner in Usson-du-Poitou, France, who has 900 patients in his practice.
He sees about 10 patients with a new diagnosis of cancer each year. In addition, about 50 of his patients are in active treatment for cancer or have finished treatment and are considered cancer survivors.
“It is not entirely realistic for us to expect practitioners who deal with hundreds of different diseases to keep up with every facet of a rapidly changing oncology landscape,” said Marco Donia, MD, an expert in immunotherapy from the University of Copenhagen.
That landscape has changed dramatically in recent years, particularly since immunotherapy was added to the arsenal. Immunotherapy is a way to fine-tune your immune system to fight cancer.
For example, in the past, patients with metastatic melanoma would have an average survival of about 1 year. But now, some patients who have responded to immunotherapy are still alive 10 years later.
Findings from the patient survey
It is important that patients stay well informed because immunotherapy is a “complex treatment that is too often mistaken for a miracle cure,” said Paris Kosmidis, MD, the co-author of the patient survey.
“The more patients know about it, the better the communication with their medical team and thus the better their outcomes are likely to be,” said Dr. Kosmidis, who is co-founder and chief medical officer of CareAcross, an online service that provides personalized education for cancer patients
The survey was of 5,589 patients with cancer who were recruited from CareAcross clients from the United Kingdom, France, Italy, Spain, and Germany.
The survey asked them about how immunotherapy works, what it costs, and its side effects.
Almost half responded “not sure/do not know,” but about a third correctly answered that immunotherapy “activates the immune system to kill cancer cells.”
Similarly, more than half thought that immunotherapy started working right away, while only 20% correctly answered that it takes several weeks to become effective.
“This is important because patients need to start their therapy with realistic expectations, for example to avoid disappointment when their symptoms take some time to disappear,” Dr. Kosmidis said.
A small group of 24 patients with lung cancer who had been treated with immunotherapy got many correct answers, but they overestimated the intensity of side effects, compared with other therapies.
“Well-informed patients who know what to expect can do 90% of the job of preventing side effects from becoming severe by having them treated early,” said Dr. Donia, of the University of Copenhagen.
Most cancer patients were also unaware of the cost of immunotherapy, which can exceed $100,000 a year, Dr. Kosmidis said.
Results of the doctor survey
The other survey presented at the meeting looked at how much doctors know about survival for 12 of the most common cancers.
Dr. Murphy and colleagues asked 301 noncancer doctors and 46 cancer specialists to estimate the percentage of patients who could be expected to live for 5 years after diagnosis (a measure known as the 5-year survival rate).
Answers from the two groups were compared and graded according to cancer survival statistics from the National Cancer Registry of Ireland.
Both groups of doctors had a hard time estimating the survival of common cancers.
Nononcologists accurately predicted 5-year survival for just two of the cancer types, while the cancer specialists got it right for four cancer types.
However, the noncancer doctors had a more pessimistic outlook on cancer survival generally and severely underestimated the chances of survival in specific cancers, particularly stage IV breast cancer. The survival for this cancer has “evolved considerably over time and now reaches 40% in Ireland,” Dr. Murphy pointed out.
“These results are in line with what we had expected because most physicians’ knowledge of oncology dates back to whatever education they received during their years of training, so their perceptions of cancer prognosis are likely to lag behind the major survival gains achieved in the recent past,” Dr. Murphy said.

He sees about 10 patients with a new diagnosis of cancer each year. In addition, about 50 of his patients are in active treatment for cancer or have finished treatment and are considered cancer survivors.
“It is not entirely realistic for us to expect practitioners who deal with hundreds of different diseases to keep up with every facet of a rapidly changing oncology landscape,” said Marco Donia, MD, an expert in immunotherapy from the University of Copenhagen.
That landscape has changed dramatically in recent years, particularly since immunotherapy was added to the arsenal. Immunotherapy is a way to fine-tune your immune system to fight cancer.
For example, in the past, patients with metastatic melanoma would have an average survival of about 1 year. But now, some patients who have responded to immunotherapy are still alive 10 years later.
Findings from the patient survey
It is important that patients stay well informed because immunotherapy is a “complex treatment that is too often mistaken for a miracle cure,” said Paris Kosmidis, MD, the co-author of the patient survey.
“The more patients know about it, the better the communication with their medical team and thus the better their outcomes are likely to be,” said Dr. Kosmidis, who is co-founder and chief medical officer of CareAcross, an online service that provides personalized education for cancer patients
The survey was of 5,589 patients with cancer who were recruited from CareAcross clients from the United Kingdom, France, Italy, Spain, and Germany.
The survey asked them about how immunotherapy works, what it costs, and its side effects.
Almost half responded “not sure/do not know,” but about a third correctly answered that immunotherapy “activates the immune system to kill cancer cells.”
Similarly, more than half thought that immunotherapy started working right away, while only 20% correctly answered that it takes several weeks to become effective.
“This is important because patients need to start their therapy with realistic expectations, for example to avoid disappointment when their symptoms take some time to disappear,” Dr. Kosmidis said.
A small group of 24 patients with lung cancer who had been treated with immunotherapy got many correct answers, but they overestimated the intensity of side effects, compared with other therapies.
“Well-informed patients who know what to expect can do 90% of the job of preventing side effects from becoming severe by having them treated early,” said Dr. Donia, of the University of Copenhagen.
Most cancer patients were also unaware of the cost of immunotherapy, which can exceed $100,000 a year, Dr. Kosmidis said.
Results of the doctor survey
The other survey presented at the meeting looked at how much doctors know about survival for 12 of the most common cancers.
Dr. Murphy and colleagues asked 301 noncancer doctors and 46 cancer specialists to estimate the percentage of patients who could be expected to live for 5 years after diagnosis (a measure known as the 5-year survival rate).
Answers from the two groups were compared and graded according to cancer survival statistics from the National Cancer Registry of Ireland.
Both groups of doctors had a hard time estimating the survival of common cancers.
Nononcologists accurately predicted 5-year survival for just two of the cancer types, while the cancer specialists got it right for four cancer types.
However, the noncancer doctors had a more pessimistic outlook on cancer survival generally and severely underestimated the chances of survival in specific cancers, particularly stage IV breast cancer. The survival for this cancer has “evolved considerably over time and now reaches 40% in Ireland,” Dr. Murphy pointed out.
“These results are in line with what we had expected because most physicians’ knowledge of oncology dates back to whatever education they received during their years of training, so their perceptions of cancer prognosis are likely to lag behind the major survival gains achieved in the recent past,” Dr. Murphy said.

Methylation patterns correlate with prognosis in children with T-ALL
In childhood patients with T-cell acute lymphoblastic leukemia (T-ALL) the hypomethylation status of the arginine synthetase (ASNS) gene was significantly associated with poor therapeutic outcome, according to the results of a Japanese cohort study published online in Blood Advances.
Researchers Koshi Akahane, PHD, of the University of Yamanashi, Kofu, Japan, and colleagues conducted a comprehensive genetic analysis of diagnostic samples of 22 cell lines from childhood patients with T-ALL in Japan.
They also correlated known methylation status with outcomes in two large patient cohorts of Japanese children with T-ALL: the Tokyo Children’s Cancer Study Group (n = 57) and the Japan Association of Childhood Leukemia Study Group (n = 20).
Methylation results
For the 22 cell lines tested, sequencing technology revealed a stepwise allele-specific methylation of the ASNS gene. Mean ASNS gene expression level was significantly upregulated in 14 weakly methylated cell lines (P = .0001), but not significantly upregulated in 3 intermediately methylated cell lines (P = .25) or in 5 highly methylated cell lines (P = .063).
Among the 77 patient cohorts, 20 (26%) samples showed high methylation (> 66.7%), while 15 (19%) samples and 42 (55%) samples showed intermediate (33.3%-66.7%) and weak (< 33.3%) methylation status, respectively.
For the 75 patients where information was provided on outcomes, 25 patients (33%) showed induction failure or disease relapse. A highly methylated status of the ASNS gene was significantly more common in non-refractory/relapse cases (18/50 cases, 36%), while intermediately or weakly methylated status was more common in refractory/relapsed cases (23/25 cases, 92 %; P = .0001). In a log-rank test, the patients with weakly methylated status of the ASNS gene showed significantly shorter event-free survival and overall survival than the patients with an intermediate or highly methylated status (P = .00012 and P = .00016, respectively).
Asparaginase sensitivity
Asparaginase treatment is a key component of chemotherapy for patients with T-ALL, according to the researchers. Asparaginase depletes serum asparagine by deamination into aspartic acid. While normal hematopoietic cells can survive due to ASNS activity, leukemia cells are expected to undergo apoptosis due to silencing of the ASNS gene.
ASNS hypomethylation status was significantly associated with poor therapeutic outcome, and all cases with the poor prognostic SPI1 fusion exclusively showed ASNS hypomethylation status. These observations demonstrate that ASNS hypomethylation status is associated with asparaginase resistance, the researchers stated.
“ASNS methylation status may be a clinically useful biomarker to predict sensitivity to asparaginase therapy in T-ALL patients. Considering the severe complications of asparaginase therapy particularly in adolescents and adults, stratifying prospective asparaginase therapy according to ASNS methylation status may be beneficial for safer and more effective treatment of T-ALL patients,” the researchers concluded.
The authors reported that they had no conflicts of interest.

Most community-based oncologists skip biomarker testing
A recent survey shows that fewer than half of community oncologists use biomarker testing to guide patient discussions about treatment, which compares with 73% of academic clinicians.
The findings, reported at the 2020 World Conference on Lung Cancer, which was rescheduled for January 2021, highlight the potential for unequal application of the latest advances in cancer genomics and targeted therapies throughout the health care system, which could worsen existing disparities in underserved populations, according to Leigh Boehmer, PharmD, medical director for the Association of Community Cancer Centers, Rockville, Md.
The survey – a mixed-methods approach for assessing practice patterns, attitudes, barriers, and resource needs related to biomarker testing among clinicians – was developed by the ACCC in partnership with the LUNGevity Foundation and administered to clinicians caring for patients with non–small cell lung cancer who are uninsured or covered by Medicaid.
Of 99 respondents, more than 85% were physicians and 68% worked in a community setting. Only 40% indicated they were very familiar or extremely familiar with 2018 Molecular Testing Guidelines for Lung Cancer from the College of American Pathologists, the International Association for the Study of Lung Cancer, and the Association for Molecular Pathology.
Clinicians were most confident about selecting appropriate tests to use, interpreting test results, and prognosticating based on test results, with 77%, 74%, and 74%, respectively, saying they are very confident or extremely confident in those areas. They were less confident about determining when to order testing and in coordinating care across the multidisciplinary team, with 59% and 64%, respectively, saying they were very confident or extremely confident in those areas, Dr. Boehmer reported at the conference.
The shortcomings with respect to communication across teams were echoed in two focus groups convened to further validate the survey results, he noted.
As for the reasons why clinicians ordered biomarker testing, 88% and 82% of community and academic clinicians, respectively, said they did so to help make targeted treatment decisions.
“Only 48% of community clinicians indicated that they use biomarker testing to guide patient discussions, compared to 73% of academic clinicians,” he said. “That finding was considered statistically significant.”
With respect to decision-making about biomarker testing, 41% said they prefer to share the responsibility with patients, whereas 52% said they prefer to make the final decision.
“Shedding further light on this situation, focus group participants expressed that patients lacked comprehension and interest about what testing entails and what testing means for their treatment options,” Dr. Boehmer noted.
In order to make more informed decisions about biomarker testing, respondents said they need more information on financial resources for patient assistance (26%) and education around both published guidelines and practical implications of the clinical data (21%).
When asked about patients’ information needs, 23% said their patients need psychosocial support, 22% said they need financial assistance, and 9% said their patients have no additional resource needs.
However, only 27% said they provide patients with resources related to psychosocial support services, and only 44% share financial assistance information, he said.
Further, the fact that 9% said their patients need no additional resources represents “a disconnect” from the findings of the survey and focus groups, he added.
“We believe that this study identifies key areas of ongoing clinician need related to biomarker testing, including things like increased guideline familiarity, practical applications of guideline-concordant testing, and … how to optimally coordinate multidisciplinary care delivery,” Dr. Boehmer said. “Professional organizations … in partnership with patient advocacy organizations or groups should focus on developing those patient education materials … and tools for improving patient-clinician discussions about biomarker testing.”
The ACCC will be working with the LUNGevity Foundation and the Center for Business Models in Healthcare to develop an intervention to ensure that such discussions are “easily integrated into the care process for every patient,” he noted.
Such efforts are important for ensuring that clinicians are informed about the value of biomarker testing and about guidelines for testing so that patients receive the best possible care, said invited discussant Joshua Sabari, MD, of New York University Langone Health’s Perlmutter Cancer Center.
“I know that, in clinic, when meeting a new patient with non–small cell lung cancer, it’s critical to understand the driver alteration, not only for prognosis, but also for goals-of-care discussion, as well as potential treatment option,” Dr. Sabari said.

REPORTING FROM WCLC 2020
Immunotherapy for cancer patients with poor PS needs a rethink
The findings have prompted an expert to argue against the use of immunotherapy for such patients, who may have little time left and very little chance of benefiting.
“It is quite clear from clinical practice that most patients with limited PS do very poorly and do not benefit from immune check point inhibitors (ICI),” Jason Luke, MD, UPMC Hillman Cancer Center and the University of Pittsburgh, said in an email.
“So, my strong opinion is that patients should not be getting an immunotherapy just because it might not cause as many side effects as chemotherapy,” he added.
“Instead of giving an immunotherapy with little chance of success, patients and families deserve to have a direct conversation about what realistic expectations [might be] and how we as the oncology community can support them to achieve whatever their personal goals are in the time that they have left,” he emphasized.
Dr. Luke was the lead author of an editorial in which he commented on the study. Both the study and the editorial were published online in JCO Oncology Practice.
Variety of cancers
The study was conducted by Mridula Krishnan, MD, Nebraska Medicine Fred and Pamela Buffett Cancer Center, Omaha, Nebraska, and colleagues.
The team reviewed 257 patients who had been treated with either a programmed cell death protein–1 inhibitor or programmed cell death–ligand-1 inhibitor for a variety of advanced cancers. The drugs included pembrolizumab (Keytruda), nivolumab (Opdivo), atezolizumab (Tecentique), durvalumab (Imfinzi), and avelumab (Bavencio).
Most of the patients (71%) had good PS, with an Eastern Cooperative Oncology Group (ECOG) PS of 0-1 on initiation of immunotherapy; 29% of patients had poor PS, with an ECOG PS of greater than or equal to 2.
“The primary outcome was OS stratified by ECOG PS 0-1 versus ≥2,” note the authors. Across all tumor types, OS was superior for patients in the ECOG 0-1 PS group, the investigators note. The median OS was 12.6 months, compared with only 3.1 months for patients in the ECOG greater than or equal to 2 group (P < .001).
Moreover, overall response rates for patients with a poor PS were low. Only 8%, or 6 of 75 patients with an ECOG PS of greater than or equal to 2, achieved an objective response by RECIST criteria.
This compared to an overall response rate of 23% for patients with an ECOG PS of 0-1, the investigators note (P = .005).
Interestingly, the hospice referral rate for patients with a poor PS (67%) was similar to that of patients with a PS of 1-2 (61.9%), Dr. Krishnan and colleagues observe.
Those with a poor PS were more like to die in-hospital (28.6%) than were patients with a good PS (15.1%; P = .035). The authors point out that it is well known that outcomes with chemotherapy are worse among patients who experience a decline in functional reserve, owing to increased susceptibility to toxicity and complications.
“Regardless of age, patients with ECOG PS >2 usually have poor tolerability to chemotherapy, and this correlates with worse survival outcome,” they emphasize. There is as yet no clear guidance regarding the impact of PS on ICI treatment response, although “there should be,” Dr. Luke believes.
“In a patient with declining performance status, especially ECOG PS 3-4 but potentially 2 as well, there is little likelihood that the functional and immune reserve of the patient will be adequate to mount a robust antitumor response,” he elaborated.
“It’s not impossible, but trying for it should not come at the expense of engaging about end-of-life care and maximizing the palliative opportunities that many only have a short window of time in which to pursue,” he added.
Again, Dr. Luke strongly believes that just giving an ICI without engaging in a frank conversation with the patient and their families – which happens all too often, he feels – is absolutely not the way to go when treating patients with a poor PS and little time left.
“Patients and families might be better served by having a more direct and frank conversation about what the likelihood [is] that ICI therapy will actually do,” Dr. Luke stressed.
In their editorial, Dr. Luke and colleagues write: “Overall, we as an oncology community need to improve our communication with patients regarding goals of care and end-of-life considerations as opposed to reflexive treatment initiation,” he writes.
“Our duty, first and foremost, should focus on the person sitting in front of us – taking a step back may be the best way to move forward with compassionate care,” they add.
The authors and editorialists have disclosed no relevant financial relationships.

“Patients and families might be better served by having a more direct and frank conversation about what the likelihood [is] that ICI therapy will actually do,” Dr. Luke stressed.
In their editorial, Dr. Luke and colleagues write: “Overall, we as an oncology community need to improve our communication with patients regarding goals of care and end-of-life considerations as opposed to reflexive treatment initiation,” he writes.
“Our duty, first and foremost, should focus on the person sitting in front of us – taking a step back may be the best way to move forward with compassionate care,” they add.

The findings have prompted an expert to argue against the use of immunotherapy for such patients, who may have little time left and very little chance of benefiting.
“It is quite clear from clinical practice that most patients with limited PS do very poorly and do not benefit from immune check point inhibitors (ICI),” Jason Luke, MD, UPMC Hillman Cancer Center and the University of Pittsburgh, said in an email.
“So, my strong opinion is that patients should not be getting an immunotherapy just because it might not cause as many side effects as chemotherapy,” he added.
“Instead of giving an immunotherapy with little chance of success, patients and families deserve to have a direct conversation about what realistic expectations [might be] and how we as the oncology community can support them to achieve whatever their personal goals are in the time that they have left,” he emphasized.
Dr. Luke was the lead author of an editorial in which he commented on the study. Both the study and the editorial were published online in JCO Oncology Practice.
Variety of cancers
The study was conducted by Mridula Krishnan, MD, Nebraska Medicine Fred and Pamela Buffett Cancer Center, Omaha, Nebraska, and colleagues.
The team reviewed 257 patients who had been treated with either a programmed cell death protein–1 inhibitor or programmed cell death–ligand-1 inhibitor for a variety of advanced cancers. The drugs included pembrolizumab (Keytruda), nivolumab (Opdivo), atezolizumab (Tecentique), durvalumab (Imfinzi), and avelumab (Bavencio).
Most of the patients (71%) had good PS, with an Eastern Cooperative Oncology Group (ECOG) PS of 0-1 on initiation of immunotherapy; 29% of patients had poor PS, with an ECOG PS of greater than or equal to 2.
“The primary outcome was OS stratified by ECOG PS 0-1 versus ≥2,” note the authors. Across all tumor types, OS was superior for patients in the ECOG 0-1 PS group, the investigators note. The median OS was 12.6 months, compared with only 3.1 months for patients in the ECOG greater than or equal to 2 group (P < .001).
Moreover, overall response rates for patients with a poor PS were low. Only 8%, or 6 of 75 patients with an ECOG PS of greater than or equal to 2, achieved an objective response by RECIST criteria.
This compared to an overall response rate of 23% for patients with an ECOG PS of 0-1, the investigators note (P = .005).
Interestingly, the hospice referral rate for patients with a poor PS (67%) was similar to that of patients with a PS of 1-2 (61.9%), Dr. Krishnan and colleagues observe.
Those with a poor PS were more like to die in-hospital (28.6%) than were patients with a good PS (15.1%; P = .035). The authors point out that it is well known that outcomes with chemotherapy are worse among patients who experience a decline in functional reserve, owing to increased susceptibility to toxicity and complications.
“Regardless of age, patients with ECOG PS >2 usually have poor tolerability to chemotherapy, and this correlates with worse survival outcome,” they emphasize. There is as yet no clear guidance regarding the impact of PS on ICI treatment response, although “there should be,” Dr. Luke believes.
“In a patient with declining performance status, especially ECOG PS 3-4 but potentially 2 as well, there is little likelihood that the functional and immune reserve of the patient will be adequate to mount a robust antitumor response,” he elaborated.
“It’s not impossible, but trying for it should not come at the expense of engaging about end-of-life care and maximizing the palliative opportunities that many only have a short window of time in which to pursue,” he added.
