2021 bought welcome relief to oncologists, whose incomes generally rose as practices reopened after COVID-19 restrictions were lifted and patients ventured out again, concludes the latest Medscape Oncologist Wealth & Debt Report 2022.

Comparing the findings with those in the larger Medscape Physician Wealth & Debt Report 2022, which surveyed more than 13,000 physicians in 29 specialties, the findings for oncologists show how they compare with those who chose other paths in medicine.

Oncologists’ income rose, on average, by 2% in the past year and now stands at an average of $411,000 annually, up from $403,000 in the 2021 report.

This puts oncologists in the top third of specialties, with plastic surgeons again in the top slot (with average income of $576,000 in 2022).

One-fifth (20%) of oncologists surveyed reported a family worth of more than $5 million, which represents substantial family wealth, the report comments.

However, 22% of oncologists reported that their family net worth was less than $500,000, and another 10% estimated that it to fall between $500,000 and $1 million.

For comparison, the average U.S. family net worth is about $749,000, according to data from the Federal Reserve.
 

Most live ‘within their means’

Most oncologists (94%) and also most (94%) of all of the physicians surveyed said that they live within or below their means.

How does one do this? Just paying off credit cards each month and contributing enough to a 401(k) account to receive an employer match does not meet this standard, said Joel Greenwald MD, CFP, a wealth management advisor for physicians. To live within or below your means, you also need to be saving at least 20% toward retirement, pay down student loans, contribute to your kids’ college savings, and set aside rainy day cash, he explained.

When physicians were asked about their favorite cost-cutting tactics, replies included bringing lunch to work, keeping a car for 15 years, and carrying out their own household maintenance and repairs. One doctor described a “24-hour rule” when it comes to shopping: “Revisit the desired purchase after 24 hours to see if it’s still desired.”

But how well do these tactics go down with ‘the other half’ and the rest of the household? Two-thirds (66%) of oncologists, and a similar proportion of all physicians, said that they argue with their significant other about spending. This appears to be high in comparison with the finding from a recent survey that across the United States, about one in four couples (25%) argue about money at least once a month.

Regarding spending, the top expense among oncologists was for childcare (16%), private tuition for offspring (14%), mortgage on a second home (14%), college tuition for offspring (14%), and a car lease (12%).

Around 17% of oncologists reported that they are still paying off their own college or medical school loans. For this statistic, they are about in the middle of all specialties.

The report notes that freeing oneself from medical school debt is very costly. Physicians in the United States pay an average of $356,000-$440,000, about half of which is interest.
 

Little change over 2021

The COVID pandemic had much less of an impact on physicians than it had on the general population when it comes to keeping up with payments, and most physicians were not affected. Only 3% of oncologists said they fell behind with payments for mortgage; 6% fell behind with payments for other bills.

In comparison, nearly half (46%) of Americans missed one or more payments of rent or mortgage because of COVID, according to a 2021 industry survey.

Over the past year, most oncologists (70%) did not change their spending habits, and only 11% cut expenses by deferring or refinancing loans. Also, most oncologists (75%) avoided major financial loses. Only 8% reported financial losses because of problems at their medical practice.

However, a slightly higher percentage of oncologists reported a stock or company investment that had turned sour in 2022 (37%) in comparison with 2021 (28%).

About one in four patients with non–small cell lung cancer (NSCLC) have an unsatisfactory antibody response to the Omicron variant following COVID-19 vaccination, according to a new study.

The study was published in the Journal of Clinical Oncology.

“Booster vaccination increased binding and neutralizing antibody titers to Omicron, but antibody titers declined after 3 months. These data highlight the concern for patients with cancer given the rapid spread of SARS-CoV-2 Omicron variant,” wrote the authors, who were led by Rafi Ahmed, PhD, Emory University, Atlanta.

Researchers found that 18% had no detectable antibody at all and active treatment type had no association with vaccine response.

Researchers examined antibody titers among 82 NSCLC patients and 53 healthy volunteers. They collected blood samples longitudinally for analysis. While most patients had binding and neutralizing antibody titers that were comparable with healthy volunteers, 25% had poor responses, which led to six- to sevenfold lower titers than healthy controls. There was no association between worse vaccine responses and history of programmed death–1 monotherapy, chemotherapy, or both in combination. Receipt of a booster vaccine improved binding and neutralizing antibody titers to both the wild type and the Omicron variant, but 2-4 months after the booster there was a five- to sevenfold decrease in neutralizing titers to both the wild type and Omicron variant.

“This study indicates both the need to monitor our patients with lung cancer for response to COVID-19 mRNA vaccines, identify the nonresponders for follow-up and further attempts at immunization, and continue collecting and analyzing clinicodemographic information and biospecimens from our patients,” wrote the authors of an accompanying editorial.

Although the findings reveal potential concerns, the good news is that most patients NSCLC patients do respond normally to COVID-19 vaccination, said John D. Minna, MD, University of Texas Southwestern Medical Center, Dallas, lead author of the editorial.

He offered some advice to physicians. “You can test your patients using currently available [Clinical Laboratory Improvement Amendments]–approved lab tests to determine what their antibody titers are. This should be done after boosting since titers will go down after time. We know that if a patient has lung cancer and they do get infected with SARS-CoV-2 that potentially they could develop serious COVID-19 disease. Besides giving antiviral treatment, it is important that they be closely monitored for symptoms of progression so if they need to be hospitalized it can be done in a prudent manner,” said Dr. Minna, who is director of the Hamon Center for Therapeutic Oncology Research at the University of Texas Southwestern Medical Center.

No clinical details have emerged that might predict which patients have an insufficient response to vaccination. “When we started these studies, a lot of us thought that anyone who did not develop a good antibody response would be weak or sicker. For example, [patients with] late-stage disease, or having had a lot of therapy, or perhaps immune checkpoint blockade. However, none of these things are correlated. The main advice we are giving our lung cancer patients are to get vaccinated, get boosted (double boosted), and just do the smart thing to protect yourself from exposure,” he said.

For example, when traveling on a plane, patients should wear a mask. They should also avoid large indoor events. He also recommended that, following vaccination and boosters, patients seek out CLIA-certified tests to get their titer checked.

“Upon any COVID infection, even if their titer is at or above 80%, patients should see their physician to consider treatment with Paxlovid (nirmatrelvir/ritonavir), which has emergency use authorization. For patients with a lower titer, it’s important to seek out a physician and consider Paxlovid and possibly antibody therapy. But these are individual decisions to be made with your doctor,” Dr. Minna said.

The next important research question is what happens to T-cell immune response following vaccination. “We know that a good cellular immune response is also important in preventing infection and severe infection, but we don’t yet know which persons (with or without cancer) have good T-cell responses. This information will also likely impact what we tell our patients and will add to the antibody data,” he said.

Studies are ongoing to determine specific T-cell responses to mRNA vaccines, and how well those T-cell responses respond to SARS-CoV-2 infection in the laboratory.

High oral cavity doses of radiotherapy are associated with greater risk of taste dysfunction in patients with head and neck cancer, finds a new study from JAMA Otolaryngology–Head & Neck Surgery.

Taste dysfunction can affect up to 90% of patients undergoing radiotherapy for head and neck cancer. While the ability to taste usually returns after the treatment concludes, some patients can still feel the lingering effects of radiotherapy on taste function long after the treatment concludes. It can lead to weight loss and dry mouth which can, in turn, negatively affect quality of life.

“Taste dysfunction has profound effects on quality of life in patients with head and neck cancer, and the oral cavity dose could be significantly lower with modern radiotherapy techniques,” wrote the researchers, who were led by Miao-Fen Chen, MD, PhD, of Chang Gung University, Taoyuan City, Taiwan. “This study provides useful dose constraints of the oral cavity that may be associated with reduced taste dysfunction.”

Degradation of taste is an important quality of life factor for head and neck cancer patients. A 2021 systematic review published in the journal Radiotherapy and Oncology found that acute taste dysfunction affected 96% of patients as measured objectively, and 79% as measured subjectively. While most patients recover an estimated 23-53% of patients experience long-term dysfunction.

In 2019, a study published in the journal Chemical Senses found that 31% of head and neck cancer patients had long-term changes to taste at 27 months after intensity-modulated radiotherapy (IMRT), with dysfunction associated with glossectomy and oral cavity radiation doses greater than 50 Gy, but the study only used one quality of life subjective measure to evaluate taste function.

In the new JAMA study, researchers reported the results of a longitudinal using the whole-mouth solution method for basic tastes, including salt, sweet, sour, and bitter.
 

Study methodology

The study included 87 patients (mean age, 58 years; 90% men) who were enrolled between 2017 and 2020 from a single hospital. 45 patients received primary intensity-modulated radiotherapy and 42 received postoperative radiotherapy. 78 patients received volumetric arc therapy, and 9 received intensity-modulated radiotherapy. The radiotherapy was directed to minimize the effect on the parotid glands and oral cavity.

Researchers measured taste dysfunction according to detection thresholds based on solutions with different concentrations. After moving the solution around the mouth and spitting it out, patients were asked to identify taste components. Following a water rinse, they tested a solution with another concentration of taste components. A number was assigned based on the concentration level they were able to detect, with nigher numbers indicating greater sensitivity.

Two to four weeks after initiation of radiotherapy, there were drops in taste scores for salt (4.7 to 1.4), sweet (4.2 to 1.8), sour (4.5 to 2.3), and bitter (4.7 to 1.2). 1 week after radiotherapy, those mean scores increased to 2.6, 2.6, 2.9, and 2.3 respectively. Over the following 3 months, mean scores reflected general recovery to near preradiotherapy levels (4.2, 3.9, 4.1, and 4.0, respectively). At 6 months and 1 year, the scores were equivalent to preradiotherapy levels.

Objective taste tests were performed on 81 participants. 33.3% had taste dysfunction 6 months after radiotherapy. 6 months after, 8.9% had taste dysfunction. At 3 months following radiotherapy, taste dysfunction was associated with an oral cavity mean dose of 4,000 cGy or higher (relative risk, 2.87; 95% confidence interval, 1.21-6.81) or 5,000 cGy or higher (RR, 2.04; 95% CI, 1.12-3.72). At 6 months, taste dysfunction was predicted by glossectomy (RR, 5.63; 95% CI, 1.12-28.15) and oral cavity mean dose 5,000 cGy or greater (RR, 7.79; 95% CI, 0.93-64.92).

The researchers quantified the relationship between mean oral cavity dose and probability of developing taste dysfunction at 3 and 6 months. 3 months after radiotherapy, 25 Gy predicted a 15% chance, 38 Gy predicted a 25% chance, and 60 Gy predicted a 50% chance. At 6 months, the numbers were 57, 60, and 64 Gy.

The study was limited by being conducted at a single center and its small sample size, and it recruited patients varied significantly in treatment modality and disease subtype.

High oral cavity doses of radiotherapy are associated with greater risk of taste dysfunction in patients with head and neck cancer, finds a new study from JAMA Otolaryngology–Head & Neck Surgery.

Taste dysfunction can affect up to 90% of patients undergoing radiotherapy for head and neck cancer. While the ability to taste usually returns after the treatment concludes, some patients can still feel the lingering effects of radiotherapy on taste function long after the treatment concludes. It can lead to weight loss and dry mouth which can, in turn, negatively affect quality of life.

“Taste dysfunction has profound effects on quality of life in patients with head and neck cancer, and the oral cavity dose could be significantly lower with modern radiotherapy techniques,” wrote the researchers, who were led by Miao-Fen Chen, MD, PhD, of Chang Gung University, Taoyuan City, Taiwan. “This study provides useful dose constraints of the oral cavity that may be associated with reduced taste dysfunction.”

Degradation of taste is an important quality of life factor for head and neck cancer patients. A 2021 systematic review published in the journal Radiotherapy and Oncology found that acute taste dysfunction affected 96% of patients as measured objectively, and 79% as measured subjectively. While most patients recover an estimated 23-53% of patients experience long-term dysfunction.

In 2019, a study published in the journal Chemical Senses found that 31% of head and neck cancer patients had long-term changes to taste at 27 months after intensity-modulated radiotherapy (IMRT), with dysfunction associated with glossectomy and oral cavity radiation doses greater than 50 Gy, but the study only used one quality of life subjective measure to evaluate taste function.

In the new JAMA study, researchers reported the results of a longitudinal using the whole-mouth solution method for basic tastes, including salt, sweet, sour, and bitter.
 

Study methodology

The study included 87 patients (mean age, 58 years; 90% men) who were enrolled between 2017 and 2020 from a single hospital. 45 patients received primary intensity-modulated radiotherapy and 42 received postoperative radiotherapy. 78 patients received volumetric arc therapy, and 9 received intensity-modulated radiotherapy. The radiotherapy was directed to minimize the effect on the parotid glands and oral cavity.

Researchers measured taste dysfunction according to detection thresholds based on solutions with different concentrations. After moving the solution around the mouth and spitting it out, patients were asked to identify taste components. Following a water rinse, they tested a solution with another concentration of taste components. A number was assigned based on the concentration level they were able to detect, with nigher numbers indicating greater sensitivity.

Two to four weeks after initiation of radiotherapy, there were drops in taste scores for salt (4.7 to 1.4), sweet (4.2 to 1.8), sour (4.5 to 2.3), and bitter (4.7 to 1.2). 1 week after radiotherapy, those mean scores increased to 2.6, 2.6, 2.9, and 2.3 respectively. Over the following 3 months, mean scores reflected general recovery to near preradiotherapy levels (4.2, 3.9, 4.1, and 4.0, respectively). At 6 months and 1 year, the scores were equivalent to preradiotherapy levels.

Objective taste tests were performed on 81 participants. 33.3% had taste dysfunction 6 months after radiotherapy. 6 months after, 8.9% had taste dysfunction. At 3 months following radiotherapy, taste dysfunction was associated with an oral cavity mean dose of 4,000 cGy or higher (relative risk, 2.87; 95% confidence interval, 1.21-6.81) or 5,000 cGy or higher (RR, 2.04; 95% CI, 1.12-3.72). At 6 months, taste dysfunction was predicted by glossectomy (RR, 5.63; 95% CI, 1.12-28.15) and oral cavity mean dose 5,000 cGy or greater (RR, 7.79; 95% CI, 0.93-64.92).

The researchers quantified the relationship between mean oral cavity dose and probability of developing taste dysfunction at 3 and 6 months. 3 months after radiotherapy, 25 Gy predicted a 15% chance, 38 Gy predicted a 25% chance, and 60 Gy predicted a 50% chance. At 6 months, the numbers were 57, 60, and 64 Gy.

The study was limited by being conducted at a single center and its small sample size, and it recruited patients varied significantly in treatment modality and disease subtype.

High oral cavity doses of radiotherapy are associated with greater risk of taste dysfunction in patients with head and neck cancer, finds a new study from JAMA Otolaryngology–Head & Neck Surgery.

Taste dysfunction can affect up to 90% of patients undergoing radiotherapy for head and neck cancer. While the ability to taste usually returns after the treatment concludes, some patients can still feel the lingering effects of radiotherapy on taste function long after the treatment concludes. It can lead to weight loss and dry mouth which can, in turn, negatively affect quality of life.

“Taste dysfunction has profound effects on quality of life in patients with head and neck cancer, and the oral cavity dose could be significantly lower with modern radiotherapy techniques,” wrote the researchers, who were led by Miao-Fen Chen, MD, PhD, of Chang Gung University, Taoyuan City, Taiwan. “This study provides useful dose constraints of the oral cavity that may be associated with reduced taste dysfunction.”

New results with quadruple drug therapy in the frontline treatment of multiple myeloma (MM) are prompting experts to speculate that stem cell transplantation may soon be able to take a back seat in the treatment of newly diagnosed disease.

“It is not a big leap of faith to imagine that, in the near future, with the availability of quadruplets and T-cell therapies, the role of high-dose melphalan and autologous stem cell transplant will be diminished,” said Dickran Kazandjian, MD, and Ola Landgren, MD, PhD, of the myeloma division, Sylvester Comprehensive Cancer Center, University of Miami.

They commented in a editorial in JAMA Oncology, prompted by a paper describing new results with a novel quadruple combination of therapies. These treatments included the monoclonal antibody elotuzumab (Empliciti) added onto the established backbone of carfilzomib (Kyprolis), lenalidomide (Revlimid), and dexamethasone (known as KRd).

“Regardless of what the future holds for elotuzumab-based combinations, it is clear that the new treatment paradigm of newly diagnosed MM will incorporate antibody-based quadruplet regimens,” the editorialists commented.

“Novel immunotherapies are here to stay,” they added, “as they are already transforming the lives of patients with multiple MM and bringing a bright horizon to the treatment landscape.”
 

Study details

The trial of the novel quadruplet regimen was a multicenter, single-arm, phase 2 study that involved 46 patients with newly diagnosed multiple myeloma, explain first author Benjamin A. Derman, MD, of the University of Chicago Medical Center, and colleagues.

These patients had a median age of 62; more than two-thirds were male (72%) and White (70%). About half (48%) had high-risk cytogenetic abnormalities.

All patients were treated with 12 cycles of the quadruple therapy Elo-KRd regimen. They underwent bone marrow assessment of measurable residual disease (MRD; with 10-5 sensitivity) after cycle 8 and cycle 12.

“An MRD-adapted treatment approach is rational because it may identify which patients can be administered shorter courses of intensive therapy without compromising efficacy,” the authors explained.

Patients who had MRD negativity at both time points did not receive further Elo-KRd, while patients who converted from MRD positivity to negativity in between cycles 8 and 12 received 6 additional cycles of Elo-KRd. Those who remained MRD positive or converted to positivity after 12 cycles received an additional 12 cycles of Elo-KRd.

Following Elo-KRd treatment, all patients transitioned to triple therapy with Elo-Rd (with no carfilzomib), for indefinite maintenance therapy or until disease progression.

For the primary endpoint, the rate of stringent complete response and/or MRD-negativity after cycle 8 was 58% (26 of 45), meeting the predefined definition of efficacy. 

Importantly, 26% of patients converted from MRD positivity after cycle 8 to negativity at a later time point, while 50% of patients reached 1-year sustained MRD negativity.

Overall, the estimated 3-year, progression-free survival was 72%, and the rate was 92% for patients with MRD-negativity at cycle 8. The overall survival rate was 78%.

The most common grade 3 or 4 adverse events were lung and nonpulmonary infections (13% and 11%, respectively), and one patient had a grade 5 MI. Three patients discontinued the treatment because of intolerance.

“An MRD-adapted design using elotuzumab and weekly KRd without autologous stem cell transplantation showed a high rate of stringent complete response (sCR) and/or MRD-negativity and durable responses,” the authors wrote.

“This approach provides support for further evaluation of MRD-guided de-escalation of therapy to decrease treatment exposure while sustaining deep responses.”

To better assess the difference of the therapy versus treatment including stem cell transplantation, a phase 3, randomized trial is currently underway to compare the Elo-KRd regimen against KRd with autologous stem cell transplant in newly diagnosed MM.

“If Elo-KRd proves superior, a randomized comparison of Elo versus anti-CD38 mAb-based quadruplets would help determine the optimal combination of therapies in the frontline setting,” the authors noted.
 

Randomized trial anticipated to clarify benefit

In their editorial, Dr. Kazandjian and Dr. Landgren agreed with the authors that the role of elotuzumab needs to be better clarified in a randomized trial setting.

Elotuzumab received FDA approval in 2015 based on results from the ELOQUENT-2 study, which showed improved progression-free survival and overall survival with the addition of elotuzumab to lenalidomide and dexamethasone in patients with multiple myeloma who have previously received one to three other therapies.

However, the editorialists pointed out that recently published results from the randomized ELOQUENT-1 trial of lenalidomide and dexamethasone with and without elotuzumab showed the addition of elotuzumab was not associated with a statistically significant difference in progression-free survival.

The editorialists also pointed out that, in the setting of newly diagnosed multiple myeloma, another recent, similarly designed study found that the backbone regimen of carfilzomib, lenalidomide, and dexamethasone – on its own – was also associated with a favorable MRD-negative rate of 62%.

In addition, several studies involving novel quadruple treatments with the monoclonal antibody daratumumab (Darzalex) instead of elotuzumab, have also shown benefit in newly diagnosed multiple myeloma, resulting in high rates of MRD negativity.

Collectively, the findings bode well for the quadruple regimens in the treatment of MM, the editorialists emphasized.

“Importantly, with the rate of deep remissions observed with antibody-based quadruplet therapies, one may question the role of using early high-dose melphalan and autologous stem cell transplant in every patient, especially in those who have achieved MRD negativity with the quadruplet alone,” they added.

The study was sponsored in part by Amgen, Bristol-Myers Squibb, and the Multiple Myeloma Research Consortium. Dr. Derman reported advisory board fees from Sanofi, Janssen, and COTA Healthcare; honoraria from PleXus Communications and MJH Life Sciences. Dr. Kazandjian declares receiving advisory board or consulting fees from Bristol-Myers Squibb, Sanofi, and Arcellx outside the submitted work. Dr. Landgren has received grant support from numerous organizations and pharmaceutical companies. Dr. Landgren has also received honoraria for scientific talks/participated in advisory boards for Adaptive Biotech, Amgen, Binding Site, Bristol-Myers Squibb, Celgene, Cellectis, Glenmark, Janssen, Juno, and Pfizer, and served on independent data monitoring committees for international randomized trials by Takeda, Merck, Janssen, and Theradex.
