Dogs show potential as medical detectives in breast cancer
Breast cancer screening using urine samples based on the volatile organic compounds (VOCs) sensed by a trained dog is feasible, according to a preliminary study published in the journal Biology June 10.
“The extrapolation of our results to widespread implementation is still uncertain,” wrote Shoko Kure, MD, PhD, of Nippon Medical School in Tokyo, and colleagues. “However, even if few dogs could be trained to detect breast cancer, the result may open the door to a robust and inexpensive way to detect breast cancer.” They added that “dog cancer detection is entirely noninvasive, safe and easy for both patients and everyone.”
Early detection of breast cancer, which is the leading cause of death globally, is essential for more efficient treatment. While mammography can detect asymptomatic breast cancer and reduce mortality, it has a poor compliance, is less sensitive in dense breast tissue, detects nonmalignant lesions, and has not been shown to reduce mortality in women younger than 40. VOCs are emitted in the breath, blood, and urine, with different volatile patterns correlated with a variety of diseases including cancers, which dogs can be trained to detect. Breast cancer screening by dog sniffing of the VOCs in urine samples has not been attempted.
Dogs have been used as medical detectives for several cancers and conditions. A study published in 2018 showed that trained dogs who were able to differentiate the specific odor from the metabolic waste of breast cancer in vitro could identify that of colorectal cancer, and vice versa. More recently, research showed that trained dogs could detect advanced prostate cancer in urine samples with high specificity and sensitivity. In this double-blinded pilot study, two dogs were trained to detect Gleason 9 prostate cancer in urine collected from biopsy-confirmed patients. The canine olfaction system was 71% sensitive and as much as 76% specific at detecting Gleason 9 cancer. Along with cancer, trained dogs have been shown to identify people with COVID-19, even those who were asymptomatic. In this study, dogs who sniffed swab samples of armpit sweat could identify which samples came from patients infected with COVID-19 with up to 100% accuracy, while ruling out infection with up to 99% accuracy.
The double-blind study by Dr. Kure aimed to assess the potential of VOCs in urine samples for breast cancer screening by using a single trained sniffer dog – in this case a 9-year-old female Labrador retriever. Urine samples from 40 patients with primary breast cancer and 142 patients with non-breast malignant diseases were included along with samples from 18 healthy volunteers. In 40 times out of 40 runs of the double-blind test, the dog correctly identified urine samples of patients with breast cancer, with 100% sensitivity and 100% specificity.
“The dog in this test successfully differentiated breast cancer from non-breast malignancies and healthy controls,” the authors wrote. “This is the first, preliminary study indicating the feasibility of developing a new breast cancer screening method using urine samples based on VOCs.”
While the authors noted that the study was limited as it relied on one trained dog, they suggested that this method has potential in low-income countries where access to mammography is inadequate.
“Some well-trained sniffing dogs traveling around medically underserved [countries] all over the world could save many lives. Even when a healthy control was indicated by a trained dog, there would be a suspicion of undiagnosed/early-stage cancer, and the person would be advised to undergo medical screening,” the authors wrote.
The authors declared no conflicts of interest.

In and out surgeries become the norm during pandemic
Urologist Ronney Abaza, MD, a robotic surgery specialist in Dublin, Ohio, and colleagues, reviewed robotic surgeries at their hospital during COVID-19 restrictions on surgery in Ohio between March 17 and June 5, 2020, and compared them with robotic procedures before COVID-19 and after restrictions were lifted. They published their results in Urology.
Since 2016, the hospital has offered the option of same-day discharge (SDD) to all robotic urologic surgery patients, regardless of procedure or patient-specific factors.
Among patients who had surgery during COVID-19 restrictions, 98% (87/89 patients) opted for SDD versus 52% in the group having surgery before the restrictions (P < .00001). After the COVID-19 surgery restrictions were lifted, the higher rate of SDD remained at 98%.
“There were no differences in 30-day complications or readmissions between SDD and overnight patients,” the authors write.
The right patient, the right motivation for successful surgery
Brian Lane, MD, PhD, a urologic oncologist with Spectrum Health in Grand Rapids, Michigan, told this news organization that, for nephrectomies, uptake of same-day discharge will continue to be slow.
“You have to have the right patient, the right patient motivation, and the surgery has to go smoothly,” he said. “If you start sending everyone home the same day, you will certainly see readmissions,” he said.
Dr. Lane is part of the Michigan Urologic Surgery Improvement Collaborative and he said the group recently looked at same-day discharge outcomes after robotic prostatectomies with SDD as compared with 1-2 nights in the hospital.
The work has not yet been published but, “There was a slight signal that there were increased readmissions with same-day discharge vs. 0-1 day,” he said.
A paper on outcomes of same-day discharge in total knee arthroplasty in the Journal of Bone & Joint Surgery found a higher risk of perioperative complications “including component failure, surgical site infection, knee stiffness, and deep vein thrombosis.” Researchers compared outcomes between 4,391 patients who underwent outpatient TKA and 128,951 patients who underwent inpatient TKA.
But for other many surgeries, same-day discharge numbers are increasing without worsening outcomes.
A paper in the Journal of Robotic Surgery found that same-day discharge following robotic-assisted endometrial cancer staging is “safe and feasible.”
Stephen Bradley, MD, MPH, with the Minneapolis Heart Institute in Minneapolis, and colleagues write in the Journal of the American College of Cardiology: Cardiovascular Interventions that they found a large increase in the use of same-day discharge after elective percutaneous coronary intervention (PCI) was not associated with worse 30-day mortality rates or readmission.
In that study, 114,461 patients were discharged the same day they underwent PCI. The proportion of patients who had a same-day discharge increased from 4.5% in 2009 to 28.6% in the fourth quarter of 2017.
Risk-adjusted 30-day mortality did not change in that time, while risk-adjusted rehospitalization decreased over time and more quickly when patients had same-day discharge.
Deepak L. Bhatt, MD, MPH, and Jonathan G. Sung, MBCHB, both of Brigham and Women’s Hospital Heart & Vascular Center, Harvard Medical School, Boston, wrote in an accompanying article that, “Advances in the devices and techniques of PCI have improved the safety and efficacy of the procedure. In selected patients, same-day discharge has become possible, and overnight in-hospital observation can be avoided. By reducing unnecessary hospital stays, both patients and hospitals could benefit.”
Evan Garden, a medical student at Icahn School of Medicine at Mount Sinai in New York, presented findings at the American Urological Association 2021 annual meeting that show patients selected for same-day discharge after partial or radical nephrectomy did not have increased rates of postoperative complications or readmissions in the immediate postoperative period, compared with standard discharge of 1-3 days.
Case studies in nephrectomy
While several case studies have looked at the feasibility and safety of performing partial and radical nephrectomy with same-day discharge in select cases, “this topic has not been addressed on a national level,” Mr. Garden said.
Few patients who have partial or radical nephrectomies have same-day discharges. The researchers found that fewer than 1% of patients who have either procedure in the sample studied were discharged the same day.
Researchers used the American College of Surgeons National Surgical Quality Improvement Program (NSQIP) database, a nationally representative deidentified database that prospectively tracks patient characteristics and 30-day perioperative outcomes for major inpatient and outpatient surgical procedures at more than 700 hospitals.
They extracted all minimally invasive partial and radical nephrectomies from 2012 to 2019 and refined the cohort to 28,140 patients who were theoretically eligible for same-day discharge: Of those, 237 (0.8%) had SSD, and 27,903 (99.2%) had a standard-length discharge (SLD).
The team found that there were no differences in 30-day complications or readmissions between same-day discharge (Clavien-Dindo [CD] I/II, 4.22%; CD III, 0%; CD IV, 1.27%; readmission, 4.64%); and SLD (CD I/II, 4.11%; CD III, 0.95%; CD IV, 0.79%; readmission, 3.90%; all P > .05).
Controlling for demographic and clinical variables, SDD was not associated with greater risk of 30-day complications or readmissions (CD I/II: odds ratio, 1.08; 95% confidence interval, 0.57-2.048; P = .813; CD IV: OR 1.699; 95% CI, 0.537-5.375; P = .367; readmission: OR, 1.254; 95% CI, 0.681-2.31; P = .467).

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.
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.

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.

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.

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.

‘Dawn of a new era’ in the treatment of renal cell carcinoma
according to expert opinion.
The high hopes have been generated by results from the randomized, phase 3 KEYNOTE-564 trial, showing that monotherapy with pembrolizumab (Keytruda, Merck) was associated with significantly longer disease-free survival (DFS) after nephrectomy than placebo (77.3% vs. 68.1%, respectively). Median follow-up was 24 months.
The results come from the trial’s first interim analysis of data from 994 patients with clear-cell renal cell carcinoma (RCC) at high risk of recurrence.
For the pembrolizumab group, the estimated percentage alive at 24 months was 96.6%, compared with 93.5% in the placebo group (hazard ratio for death, 0.54), said Toni Choueiri, MD, of the Dana-Farber Cancer Institute, Boston, and colleagues.
However, grade 3 or higher adverse events (any cause) occurred at almost twice the rate in the pembrolizumab versus the placebo group (32.4% vs. 17.7%). The new study was published online Aug. 18, 2021, in the New England Journal of Medicine.
The study results were first presented at the 2021 American Society of Clinical Oncology annual meeting and described as likely to be practice changing in this setting, as reported by this news organization.
Currently, this patient population has “no options for adjuvant therapy to reduce the risk of recurrence that have high levels of supporting evidence,” observed the authors.
That’s about to change, as the trial results “herald the dawn of a new era in the treatment of renal cell carcinoma,” Rana McKay, MD, University of California San Diego Health, wrote in an accompanying editorial.
Multiple studies have investigated potential adjuvant therapies in RCC since the 1980s, she observed.
“For the first time, we now have an effective adjuvant immunotherapy option for patients with resected renal cell carcinoma at high risk of recurrence,” Dr. McKay said in an interview.
To date, the lack of clinically beneficial adjuvant therapy options in RCC has been “humbling,” Dr. Choueiri said in an interview. “We hope we can push the envelope further and get more patients with RCC some good options that make them live longer and better.”
Although the standard of care for patients diagnosed with locoregional RCC is partial or total nephrectomy, nearly half of patients eventually experience disease recurrence following surgery, Dr. Choueiri noted.
“No standard, globally approved adjuvant therapy options are currently available for this population,” he said. Clinical guidelines recommend patients at high risk of disease recurrence after surgery be entered into a clinical trial or undergo active surveillance.
Researchers will continue to follow the results for overall survival, a secondary endpoint. “The very early look suggests encouraging results [in overall survival] with an HR of 0.54,” Dr. Choueiri noted.
In the meantime, the prolongation of DFS represents a clear clinical benefit, said Dr. McKay, “given the magnitude of the increase” and “the limited incidence of toxic effects.”
KEYNOTE-564 will alter the adjuvant treatment landscape for RCC as a positive phase 3 trial of adjuvant immunotherapy for the disease, she added.
A number of earlier studies have investigated the use of adjuvant vascular endothelial growth factor–targeting agents in RCC. Only the 2016 Sunitinib Treatment of Renal Adjuvant Cancer (S-TRAC) trial showed improved DFS with sunitinib, compared with placebo (6.8 vs. 5.6 years). Subsequently, sunitinib was approved for adjuvant use in the United States. However, the S-TRAC trial also showed that sunitinib therapy was associated with an increased incidence of toxic effects and lower quality of life scores, and researchers did not observe any benefit in overall survival.
“Despite regulatory approval in the U.S., sunitinib is not approved for adjuvant use by the European Medicines Agency and has limited utilization in clinical practice given the low benefit-risk ratio,” Dr. McKay pointed out.
Study details
KEYNOTE-564 involved 996 patients with clear-cell RCC at high risk for recurrence after nephrectomy, with or without metastasectomy. They were randomly assigned in a 1:1 ratio to receive a 200-mg dose of adjuvant pembrolizumab or placebo given intravenously once every 3 weeks for up to 17 cycles for approximately 1 year.
The vast majority of patients enrolled in the study had localized disease with no evidence of metastases (M0) and intermediate to high or high risk of disease recurrence after partial or complete nephrectomy. However, 5.8% of patients in both the pembrolizumab and placebo groups had M1 NED (metastatic stage 1, no evidence of disease) status after nephrectomy and resection of metastatic lesions. These patients were also at intermediate to high or high risk of recurrence.
The benefit of pembrolizumab, compared with placebo, was maintained in this subgroup, said the investigators. “At this point, we continue to look at the data, but we know that there was a benefit for DFS in the population we included,” said Dr. Choueiri. “When we looked at several subgroups such as PD-L1 status, geography, gender, performance status, M0/M1, all HRs were less than 1 suggesting benefit from pembrolizumab over placebo.”
“Subset analyses by stage are going to be important to determine which group of patients will derive the most benefit,” asserted Dr. McKay. “While those with M1 NED appear to derive benefit with HR for DFS of 0.29, those with M1 NED comprise a small percentage of patient enrolled in the trial.”
Studies exploring tissue- and blood-based biomarkers, including circulating tumor DNA, will be key to identify patients at highest risk for recurrence or adjuvant treatment, Dr. McKay emphasized. “The adoption of adjuvant immune checkpoint inhibitors brings along new questions regarding patient selection, therapeutic use in patients with non–clear-cell renal cell carcinoma, and systemic treatment after recurrence during or after the receipt of adjuvant therapy.”
KEYNOTE-564 was funded by Merck. Multiple study authors including Dr. Choueiri have financial ties to the pharmaceutical industry, including Merck.

The results come from the trial’s first interim analysis of data from 994 patients with clear-cell renal cell carcinoma (RCC) at high risk of recurrence.
For the pembrolizumab group, the estimated percentage alive at 24 months was 96.6%, compared with 93.5% in the placebo group (hazard ratio for death, 0.54), said Toni Choueiri, MD, of the Dana-Farber Cancer Institute, Boston, and colleagues.
However, grade 3 or higher adverse events (any cause) occurred at almost twice the rate in the pembrolizumab versus the placebo group (32.4% vs. 17.7%). The new study was published online Aug. 18, 2021, in the New England Journal of Medicine.
The study results were first presented at the 2021 American Society of Clinical Oncology annual meeting and described as likely to be practice changing in this setting, as reported by this news organization.
Currently, this patient population has “no options for adjuvant therapy to reduce the risk of recurrence that have high levels of supporting evidence,” observed the authors.
That’s about to change, as the trial results “herald the dawn of a new era in the treatment of renal cell carcinoma,” Rana McKay, MD, University of California San Diego Health, wrote in an accompanying editorial.
Multiple studies have investigated potential adjuvant therapies in RCC since the 1980s, she observed.
“For the first time, we now have an effective adjuvant immunotherapy option for patients with resected renal cell carcinoma at high risk of recurrence,” Dr. McKay said in an interview.
To date, the lack of clinically beneficial adjuvant therapy options in RCC has been “humbling,” Dr. Choueiri said in an interview. “We hope we can push the envelope further and get more patients with RCC some good options that make them live longer and better.”
Although the standard of care for patients diagnosed with locoregional RCC is partial or total nephrectomy, nearly half of patients eventually experience disease recurrence following surgery, Dr. Choueiri noted.
“No standard, globally approved adjuvant therapy options are currently available for this population,” he said. Clinical guidelines recommend patients at high risk of disease recurrence after surgery be entered into a clinical trial or undergo active surveillance.
Researchers will continue to follow the results for overall survival, a secondary endpoint. “The very early look suggests encouraging results [in overall survival] with an HR of 0.54,” Dr. Choueiri noted.
In the meantime, the prolongation of DFS represents a clear clinical benefit, said Dr. McKay, “given the magnitude of the increase” and “the limited incidence of toxic effects.”
KEYNOTE-564 will alter the adjuvant treatment landscape for RCC as a positive phase 3 trial of adjuvant immunotherapy for the disease, she added.
A number of earlier studies have investigated the use of adjuvant vascular endothelial growth factor–targeting agents in RCC. Only the 2016 Sunitinib Treatment of Renal Adjuvant Cancer (S-TRAC) trial showed improved DFS with sunitinib, compared with placebo (6.8 vs. 5.6 years). Subsequently, sunitinib was approved for adjuvant use in the United States. However, the S-TRAC trial also showed that sunitinib therapy was associated with an increased incidence of toxic effects and lower quality of life scores, and researchers did not observe any benefit in overall survival.
“Despite regulatory approval in the U.S., sunitinib is not approved for adjuvant use by the European Medicines Agency and has limited utilization in clinical practice given the low benefit-risk ratio,” Dr. McKay pointed out.
Study details
KEYNOTE-564 involved 996 patients with clear-cell RCC at high risk for recurrence after nephrectomy, with or without metastasectomy. They were randomly assigned in a 1:1 ratio to receive a 200-mg dose of adjuvant pembrolizumab or placebo given intravenously once every 3 weeks for up to 17 cycles for approximately 1 year.
The vast majority of patients enrolled in the study had localized disease with no evidence of metastases (M0) and intermediate to high or high risk of disease recurrence after partial or complete nephrectomy. However, 5.8% of patients in both the pembrolizumab and placebo groups had M1 NED (metastatic stage 1, no evidence of disease) status after nephrectomy and resection of metastatic lesions. These patients were also at intermediate to high or high risk of recurrence.
The benefit of pembrolizumab, compared with placebo, was maintained in this subgroup, said the investigators. “At this point, we continue to look at the data, but we know that there was a benefit for DFS in the population we included,” said Dr. Choueiri. “When we looked at several subgroups such as PD-L1 status, geography, gender, performance status, M0/M1, all HRs were less than 1 suggesting benefit from pembrolizumab over placebo.”
“Subset analyses by stage are going to be important to determine which group of patients will derive the most benefit,” asserted Dr. McKay. “While those with M1 NED appear to derive benefit with HR for DFS of 0.29, those with M1 NED comprise a small percentage of patient enrolled in the trial.”
Studies exploring tissue- and blood-based biomarkers, including circulating tumor DNA, will be key to identify patients at highest risk for recurrence or adjuvant treatment, Dr. McKay emphasized. “The adoption of adjuvant immune checkpoint inhibitors brings along new questions regarding patient selection, therapeutic use in patients with non–clear-cell renal cell carcinoma, and systemic treatment after recurrence during or after the receipt of adjuvant therapy.”
KEYNOTE-564 was funded by Merck. Multiple study authors including Dr. Choueiri have financial ties to the pharmaceutical industry, including Merck.

FDA OKs belzutifan for cancers tied to von Hippel–Lindau disease
Belzutifan is a selective small-molecule inhibitor of hypoxia-inducible factor and a first-in-class drug.
The new approval is based on safety and efficacy results from the ongoing Study 004, an open-label clinical trial involving 61 patients with VHL-associated RCC with at least one measurable solid tumor localized to the kidney. Enrolled patients had other VHL-associated tumors, including CNS hemangioblastomas and pNETs.
Patients received belzutifan 120 mg once daily until disease progression or unacceptable toxicity.
The overall response rate, which was the study’s primary endpoint, was 49% in patients with VHL-associated RCC. Additional efficacy endpoints included duration of response (DoR), which was not reached. So far, 56% of responders had DoR of at least 12 months. The median time to response was 8 months.
Among the patients in the study with other VHL-associated non-RCC tumors, 24 patients with CNS hemangioblastomas had an ORR of 63%, and 12 patients with pNETs had an ORR of 83%. Median DoR was not reached,with 73% and 50% of patients having response durations of at least 12 months for CNS hemangioblastomas and pNET, respectively.
The most common adverse reactions (≥20% of patients), according to the FDA, were decreased hemoglobin, anemia, fatigue, increased creatinine, headache, dizziness, increased glucose, and nausea.
Notably, anemia and hypoxia from belzutifan use can be severe. In Study 004, anemia occurred in 90% of patients and 7% had grade 3 anemia. Patients should be transfused as clinically indicated. Erythropoiesis-stimulating agents for anemia are not recommended in patients treated with belzutifan. In Study 004, hypoxia occurred in 1.6% of patients.
Belzutifan can render some hormonal contraceptives ineffective, and belzutifan exposure during pregnancy can cause embryo-fetal harm; see full prescribing information for Welireg.
This review was conducted under Project Orbis, an initiative of the FDA Oncology Center of Excellence, and used the Real-Time Oncology Review pilot program, which streamlined data submission prior to the filing of the entire clinical application. The application was granted priority review by the FDA.

One in three cancer articles on social media has wrong info
Of the 200 most popular articles (50 each for prostate, lung, breast, and colorectal cancer), about a third (32.5%, n = 65) contained misinformation.
Among these articles containing misinformation, 76.9% (50/65) contained harmful information.
“The Internet is a leading source of health misinformation,” the study authors wrote. This is “particularly true for social media, where false information spreads faster and more broadly than fact-checked information,” they said, citing other research.
“We need to address these issues head on,” said lead author Skyler Johnson, MD, of the University of Utah’s Huntsman Cancer Institute in Salt Lake City.
“As a medical community, we can’t ignore the problem of cancer misinformation on social media or ask our patients to ignore it. We must empathize with our patients and help them when they encounter this type of information,” he said in a statement. “My goal is to help answer their questions, and provide cancer patients with accurate information that will give them the best chance for the best outcome.”
The study was published online July 22 in the Journal of the National Cancer Institute.
The study period ran from 2018 to 2019, and looked at articles posted on social media platforms Facebook, Reddit, Twitter, or Pinterest. Popularity was measured by engagement with readers, such as upvotes, comments, reactions, and shares.
Some of the articles came from long-established news entities such as CBS News, The New York Times, and medical journals, while others came from fleeting crowdfunding web pages and fledging nontraditional news sites.
One example of popular and harmful misinformation highlighted by Dr. Johnson in an interview was titled, “44-Year-Old Mother Claims CBD Oil Cured Her of Breast Cancer within 5 Months.” Posted on truththeory.com in February 2018, the article is tagged as “opinion” by the publisher and in turn links to another news story about the same woman in the UK’s Daily Mail newspaper.
The ideas and claims in such articles can be very influential, Jennifer L. Lycette, MD, suggested in a recent blog post.
“After 18 years as a cancer doctor, it sadly doesn’t come as a surprise anymore when a patient declines treatment recommendations and instead opts for ‘alternative’ treatment,” she wrote.
Sometimes, misinformation is not sensational but is still effective via clever wording and presentation, observed Brian G. Southwell, PhD, of Duke University, Durham, N.C., who has studied patients and misinformation.
“It isn’t the falsehood that is somehow magically attractive, per se, but the way that misinformation is often framed that can make it attractive,” he said in an interview.
Dr. Southwell recommends that clinicians be proactive about medical misinformation.
“Rather than expect patients to raise concerns without prompting, health care providers should invite conversations about potential misinformation with their patients,” he wrote in a recent essay in the American Journal of Public Health.
In short, ask patients what they know about the treatment of their cancer, he suggests.
“Patients don’t typically know that the misinformation they are encountering is misinformation,” said Dr. Southwell. “Approaching patients with compassion and empathy is a good first step.”
Study details
For the study, reported by Johnson et al., two National Comprehensive Cancer Network panel members were selected as content experts for each of the four cancers and were tasked with reviewing the primary medical claims in each article. The experts then completed a set of ratings to arrive at the proportion of misinformation and potential for harm in each article.
Of the 200 articles, 41.5% were from nontraditional news (digital only), 37.5% were from traditional news sources (online versions of print and/or broadcast media), 17% were from medical journals, 3% were from a crowdfunding site, and 1% were from personal blogs.
This expert review concluded that nearly one-third of the articles contained misinformation, as noted above. The misinformation was described as misleading (title not supported by text or statistics/data do not support conclusion, 28.8%), strength of the evidence mischaracterized (weak evidence portrayed as strong or vice versa, 27.7%) and unproven therapies (not studied or insufficient evidence, 26.7%).
Notably, the median number of engagements, such as likes on Twitter, for articles with misinformation was greater than that of factual articles (median, 2,300 vs. 1,600; P = .05).
In total, 30.5% of all 200 articles contained harmful information. This was described as harmful inaction (could lead to delay or not seeking medical attention for treatable/curable condition, 31.0%), economic harm (out-of-pocket financial costs associated with treatment/travel, 27.7%), harmful action (potentially toxic effects of the suggested test/treatment, 17.0%), and harmful interactions (known/unknown medical interactions with curative therapies, 16.2%).
The median number of engagements for articles with harmful information was statistically significantly greater than that of articles with correct information (median, 2,300 vs. 1,500; P = .007).
A limitation of the study is that it included only the most popular English language cancer articles.
This study was funded in part by the Huntsman Cancer Institute. Dr. Johnson, Dr. Lycette, and Dr. Southwell have disclosed no relevant financial relationships. Some study authors have ties to the pharmaceutical industry.
