Meet our newest genetically engineered frenemy, herpes
Herpes to the rescue
Let’s face it: When people hear the word “herpes,” their first thoughts are not positive. But what if herpes could be a hero?
Scientists have found a way to make a strain of herpes that kills cancer because, hey, it’s 2022, and anything is possible. Trials have been going well and this seems like a safe and effective way to fight cancer.
Viruses may be one of our oldest enemies, but it’s also been said that the enemy of my enemy is my friend. So why not make herpes the enemy of cancer, thereby turning it into our friend? The genetically modified herpes virus is injected directly into tumors, where it destroys cancer cells from within. But wait, there’s more! The patient’s immune system also senses the virus and springs into action against it and the cancer in which it is residing.
During the phase 1 trial, three of the nine patients saw tumor reduction and the therapy proved safe as well. Future trials will be able to more specifically target various cancer types and make the treatment better. For once, we are rooting for you, herpes.
A breath of not-so-fresh air
There’s nothing quite like that first real warm day of spring. You can finally open the windows and clear out the old stuffy air that’s been hanging around all winter long. It’s a ritual that’s now backed up with some science in the form of a new study. Turns out that there’s actually a fair amount of smog in the average home. That’s right, smog’s not just for the big city anymore.
As part of the HOMEChem project, a whole host of scientists gathered together under one roof in a typical suburban house and immediately started doing chores. Cooking, cleaning, the works. No, it wasn’t because they had trashed the place the night before. They had set up instrumentation all around the house to measure the chemical makeup of the air inside. A scientist’s idea of a wild party.
The results are perhaps not all that surprising, but interesting nonetheless. Your homemade smog certainly won’t kill you, but there’s both an increased amount and higher concentration of airborne toxins in indoor air, compared with outdoors. Benzene and formaldehyde were common, as were acrolein (a pulmonary toxicant emitted by lumber and burning fats) and isocyanic acid (which can react with proteins in the human body). The researchers noted that most of these chemicals can be removed with proper ventilation.
Although cleaning is certainly responsible for a fair share of the chemicals, cooking generally produced more toxic compounds, similar to what’s found in wildfire smoke. One of the researchers said this makes sense, since a wildfire can be considered an “extreme form of cooking.” Scientists may not know how to party, but their idea of a barbecue sounds … interesting. We’re looking forward to an upcoming study out of California: Can a 1-million acre wildfire adequately cook a ribeye steak?
We’re dying to try composting ... with humans, that is
We here at LOTME are not really fans of politicians, except as objects of ridicule. That is kind of fun. Whether we’re watching Fox News, listening to NPR, or reading Vladimir Putin’s fashion blog, one thing remains clear: If you want actual information, don’t ask a politician.
There are, of course, always exceptions, and we just found one: California state representative Cristina Garcia. Rep. Garcia sponsored a bill just signed into law by Gov. Gavin Newsom that legalizes the practice of human composting, the reduction of remains by “placing bodies in individual vessels and fostering gentle transformation into a nutrient-dense soil.”
Since we’ve written about this sort of thing before – Washington was the first state to legalize the process back in 2019 – we’re more interested now in what Rep. Garcia told NBC News while describing her motivation: “I’ve always wanted to be a tree. The idea of having my family sitting under my shade one day – that brings a lot of joy.” How great is that? Tree-hugging is just not enough. Be the tree.
California is the fifth state to provide its residents with the human composting option, the other three being Colorado, Oregon, and Vermont. The process “typically involves putting a body into a steel vessel, then covering it with organic materials like straw, wood chips and alfalfa. Microbes break down the corpse and the plant matter, transforming the various components into nutrient-rich soil in roughly 30 days,” Smithsonian Magazine explained.
We just happen to have some good news for Rep. Garcia about that wanting-to-be-a-tree business. She’s already pretty close. For more on that, we go to our correspondent from beyond the grave, Carl Sagan, who shares a thought about trees. And no, we couldn’t just write out his quote here. You have to hear it in Dr. Sagan’s own voice.
That’ll be one pandemic with extra distress. Hold the goals
When the COVID-19 pandemic first hit it put a lot of stuff on hold for everyone. Couldn’t eat inside at your favorite restaurant, attend that long-awaited concert, or travel out of the country. Those were all pretty bad, but it was the disruption of pursuing long-term goals that seemed to have the most effect on people’s mental health.
Investigators from the University of Waterloo (Ont.) looked at how putting such goals on hold affected people’s mental well-being. The study’s 226 participants were asked about their “COVID-frozen” goals and the degree to which they were able to actively pursue each goal and how committed they were to achieving it.
What they found was that the participants’ COVID-frozen goals were associated with feelings of psychological distress, such as anxiety, depressive symptoms, stress, and lowered life satisfaction. It was only when participants were able to disengage from goal rumination that well-being was impacted positively.
“Goal rumination is compulsive and can aggravate worries and frustrations while also taking away mental resources from other goals,” Candice Hubley, lead author and a PhD candidate in psychology, said in a written statement. So in short, you’re only stressing yourself out more about something that is far off in the distance when you could be focusing more on short-term, tangible goals instead.
Now, no one is saying to give up on your goals. Just take them one at a time. You’ll have better life satisfaction and your COVID-frozen goals will thaw out before you know it.

Despite benefits, extended-interval pembro uptake remains low
In April 2020, the Food and Drug Administration approved extended dosing for standalone pembrolizumab – 400 mg every 6 weeks instead of the standard dosing of 200 mg every 3 weeks. The shift came, in part, to reduce patient health care encounters during the early days of the COVID-19 pandemic, but also because fewer infusions save patients time and out-of-pocket costs and reduce the burden on the health care system.
The FDA deemed this move safe after pharmacologic studies and a small melanoma study found that responses and adverse events were equivalent in comparison with standard dosing.
Given the benefits, one would expect “brisk adoption” of extended-interval dosing, Garth Strohbehn, MD, an oncologist at the VA Medical Center in Ann Arbor, Mich., and colleagues wrote in a recent report in JAMA Oncology.
However, when the team reviewed data on 835 veterans from the Veterans Health Administration who began taking single-agent pembrolizumab between April 1, 2020, and July 1, 2021, only about one-third received extended-interval dosing.
Between April and January 2021, use of extended-interval dosing rose steadily to about 35% of patients but then hovered in that range through August 2021.
Among the patients, age, sex, Charlson comorbidity index, and pembrolizumab indications were well balanced between the standard-dosing and the extended-interval dosing groups.
Notably, Dr. Strohbehn and colleagues also found no difference in time-to-treatment discontinuation between patients receiving extended dosing in comparison with patients receiving standard dosing, which is “a real-world measure of clinical effectiveness,” the team said.
And there was no difference in immune-related side effects between the two regimens, as assessed by incident levothyroxine and prednisone prescriptions.
The real-world near equivalence of extended and standard dosing intervals that was demonstrated in the study is “reassuring” and helps make the case for considering it “as a best practice” for single-agent pembrolizumab, the investigators wrote.
Dr. Strohbehn remained somewhat puzzled by the low uptake of the extended-dosing option.
“I was frankly surprised by the small number of patients who received the extended-interval regimen,” Dr. Strohbehn said in an interview.
“Admittedly, there are patients who would prefer to receive standard-interval therapy, and that preference should of course be accommodated whenever possible, but in my experience, those numbers are small,” at least in the VA system, he noted.
In addition, the authors noted, there is no direct financial incentive for more frequent dosing in the VA system.
It’s possible that low uptake could stem from clinicians’ doubts about switching to an extended-interval dose, given that the FDA’s approval was based largely on a study of 44 patients with melanoma in a single-arm trial.
If that is indeed the case, the new findings – which represent the first health system–level, real-world comparative effectiveness data for standard vs. extended-interval pembrolizumab – should help address these concerns, the team said.
“This observational dataset lends further credence to [the dosing] regimens being clinically equivalent,” said Zachery Reichert, MD, PhD, a urologic oncologist at the University of Michigan, Ann Arbor, who was not involved in the study.
To address the issue, Dr. Strohbehn and his team suggested “clinical guideline promotion to overcome some of the barriers to the adoption of extended-interval pembrolizumab.”
Dr. Riechert suggested further validation of equivalent outcomes for the two regimens, more advocacy to encourage patients to ask about the 6-week option, as well as incentives from insurers to adopt it.
Dr. Strohbehn added that the situation highlights a broader issue in oncology, namely that many drugs “end up on the market with dosing regimens that haven’t necessarily been optimized.”
Across the world, investigators are conducting clinical trials “to identify the minimum dosages, frequencies, and durations patients need in order to achieve their best outcome,” Dr. Strohbehn said. In oncology, much of this effort is being led by Project Optimus, from the FDA’s Oncology Center of Excellence, he said.
The study was funded by the VA National Oncology Program. Dr. Reichert and Dr. Strohbehn have disclosed no relevant financial relationships. One investigator has received grants from Novartis, Bristol-Myers Squibb, Regeneron, and Genentech.

Weight gain linked to cancer survival in men and women
Cancer cachexia is a syndrome of weight loss that frequently occurs during cancer treatment. Consequences can include skeletal muscle loss, fatigue, functional impairment, worse quality of life, and worse survival. On the other hand, weight gain during cancer treatment has been tied to better survival.
Few studies have examined the relationship between weight gain and outcomes by sex.
“The finding that weight gain occurred in subsets of males and females is a new observation. The fact that weight gain occurs in cancer patients during anticancer treatment could confound results of clinical [trials] evaluating novel anticachexia treatments. Simultaneously studying longitudinal body weights and serum and cellular biomarkers in cancer patients might provide insights into mechanisms involved in cachexia. Increased understanding of mechanisms driving cachexia could lead to new therapeutic strategies,” said study coauthor Philip Bonomi, MD, who is an oncologist at Rush Medical College, Chicago.
“This data, although it appears to be very basic, is critically important, especially as we consider our novel interventions in the treatment of cancer cachexia,” said Eric Roeland, MD, during his presentation of the study at the annual meeting of European Society for Medical Oncology. Dr. Roeland is a medical oncologist at Oregon Health & Science University, Portland.
Dr. Roeland is also the lead author of cancer cachexia guidelines published by the American Society of Clinical Oncology in 2020. The guidelines suggest that dietary counseling can be offered to patients, but warns against routine use of enteral feeding tubes and parenteral nutrition. Although no specific drug can be recommended for cancer cachexia, progesterone analogs and corticosteroids used over the short term (weeks) can be used on a trial base to improve appetite and weight gain. While not approved in the United States, anamorelin was approved in 2020 in Japan for cancer cachexia in NSCLC, gastric cancer, pancreatic cancer, and colorectal cancer.
The new study should raise awareness of the importance of adverse effects of cancer treatments, said Karin Jordan, MD, University Hospital Heidelberg (Germany). She served as a discussant following the presentation. “As a medical oncologist, we focus a bit too much on the benefits of antineoplastic therapy, both on cure and on the survival benefit. But what is also very, very important to do is a balanced oncology treatment to focus on the risks of oncology therapies,” she said.
The study is limited by its retrospective nature and potential for bias. “The hypothesis that weight gain leads to improved survival is not really proven as it likewise may be the other way around,” Dr. Jordan said.
However, in oncology research, a phenomenon called the “obesity paradox” is increasingly catching the interest of investigators. Observational studies have shown that overweight patients with certain cancers (specifically, colorectal, endometrial and lung cancer). actually have improved overall survival as compared with normal-weight patients.
Details from the new study
The researchers pooled data 1,030 patients who participated in three phase 3 clinical trials conducted between 2005 and 2011. The patients all received platinum-based chemotherapy as part of control arms. 304 were female and 726 were male. The median age was 62. 16.7% were Asian, the mean body mass index was 24.6 kg/m2, 88.5% had stage 4 disease, 36.9% had adenocarcinoma, and 86.3% were current or former smokers.
Males and females had similar magnitudes and rate of weight gain over the course of treatment. Any weight gain was associated with improved overall survival in both males (12.7 vs. 8.0 months; hazard ratio, 0.60; P < .001) and females (16.2 vs. 10.1 months; HR, 0.65; P = .0028). Patients who had a weight gain of 2.5% of body weight or more saw an improvement in overall survival in both males (14.0 vs. 8.2 months; HR, 0.57; P < .001) and females (16.7 vs. 11.3 months; HR, 0.61; P = .0041).
Patients with a weight gain of 5% or more was associated with improved survival in males (13.6 vs. 8.9 months; HR, 0.62; P = .0001), but there was no statistically significant association in females (16.7 vs. 12.6 months; HR, 0.69; P = .1107).
Regardless of weight-gain status, males had lower survival rates than females. All of the associations were independent of smoking status.
The study was funded by Pfizer. Dr. Bonomi has received honoraria from Pfizer and Helsinn for participation in scientific advisory boards. Dr. Jordan has consulted for Amgen, Hexal, Riemser, Helsinn, Voluntis, Pfizer, and BD Solution. She has received research funding from Deutsche Krebshilfe. She has received honoraria from MSD, Merck, Amgen, Hexal, Riemser, Helsinn, Voluntis, Pfizer, Pomme-med, PharmaMar, arttemoi, OnkoUpdate, Stemline, and Roche.
Cancer cachexia is a syndrome of weight loss that frequently occurs during cancer treatment. Consequences can include skeletal muscle loss, fatigue, functional impairment, worse quality of life, and worse survival. On the other hand, weight gain during cancer treatment has been tied to better survival.
Few studies have examined the relationship between weight gain and outcomes by sex.
“The finding that weight gain occurred in subsets of males and females is a new observation. The fact that weight gain occurs in cancer patients during anticancer treatment could confound results of clinical [trials] evaluating novel anticachexia treatments. Simultaneously studying longitudinal body weights and serum and cellular biomarkers in cancer patients might provide insights into mechanisms involved in cachexia. Increased understanding of mechanisms driving cachexia could lead to new therapeutic strategies,” said study coauthor Philip Bonomi, MD, who is an oncologist at Rush Medical College, Chicago.
“This data, although it appears to be very basic, is critically important, especially as we consider our novel interventions in the treatment of cancer cachexia,” said Eric Roeland, MD, during his presentation of the study at the annual meeting of European Society for Medical Oncology. Dr. Roeland is a medical oncologist at Oregon Health & Science University, Portland.
Dr. Roeland is also the lead author of cancer cachexia guidelines published by the American Society of Clinical Oncology in 2020. The guidelines suggest that dietary counseling can be offered to patients, but warns against routine use of enteral feeding tubes and parenteral nutrition. Although no specific drug can be recommended for cancer cachexia, progesterone analogs and corticosteroids used over the short term (weeks) can be used on a trial base to improve appetite and weight gain. While not approved in the United States, anamorelin was approved in 2020 in Japan for cancer cachexia in NSCLC, gastric cancer, pancreatic cancer, and colorectal cancer.
The new study should raise awareness of the importance of adverse effects of cancer treatments, said Karin Jordan, MD, University Hospital Heidelberg (Germany). She served as a discussant following the presentation. “As a medical oncologist, we focus a bit too much on the benefits of antineoplastic therapy, both on cure and on the survival benefit. But what is also very, very important to do is a balanced oncology treatment to focus on the risks of oncology therapies,” she said.
The study is limited by its retrospective nature and potential for bias. “The hypothesis that weight gain leads to improved survival is not really proven as it likewise may be the other way around,” Dr. Jordan said.
However, in oncology research, a phenomenon called the “obesity paradox” is increasingly catching the interest of investigators. Observational studies have shown that overweight patients with certain cancers (specifically, colorectal, endometrial and lung cancer). actually have improved overall survival as compared with normal-weight patients.

FROM ESMO CONGRESS 2022
Noted oncologist ponders death, life, care inequities
In 2020, he published a book aimed at cancer specialists and their patients on how to die “with hope and dignity,” titled “Between Life and Death” (Penguin Random House India).
When Dr. Patel, the CEO of Carolina Blood and Cancer Care Associates in Rock Hill, S.C., became president of the Washington-based Community Oncology Alliance 2 years ago, he stepped into a leadership role in community oncology. As an advocate for health care payment reform on Capitol Hill, the South Carolina legislature, and within his own practice, Dr. Patel has long worked to eliminate disparities in U.S. cancer care.
This news organization spoke with Dr. Patel about his unusual career path.
Question: Your father had a great influence on you. Can you tell us more about him?
Answer: My dad was a hermit and a saint. He lost his dad when he was 4 years old and moved to the big city with his cousins. When he was 9 or so, he got a message saying that his mum was very ill. So, he and his cousin raised some money, got a doctor and one of those old, rugged jeeps, and they started driving to the village, but rains had destroyed the road. So, without penicillin, his mum died of pneumonia.
He felt that roads and doctor access were the two big factors that could have saved her life. He eventually became the Superintending Engineer for four districts in Gujarat State, building roads connecting every village, but he never gave up his simplistic, minimalist life.
When I was in elementary school, every other weekend my dad would literally dump me at the Mahatma Gandhi Ashram and come back in 2 hours. So, I’m looking at Gandhi’s cabinets, his pictures, reading about his life. So, my formative years were born in that.
Q: I read that you were intending to become an engineer and join the space race. How did your father nudge you toward medicine?
A: When I was 9 years old, my favorite movie hero died of cancer. To comfort me, my father inserted the idea into my brain: When you grow up, you can become a doctor to cure cancer. So, when I finished high school, I was 24th in the state and had an option to go to the space school in India. On the day when I was going for the interview, I could see tears in my father’s eyes, and he said, You know what, boy? I thought you’re going to become a doctor and cure cancer. So, to honor him, I went to med school instead.
Q: I understand that your father also triggered your interest in photography?
A: I started photographing Kutchi tribal people in 1977, after I bought a camera from a famous architect [Hasmukh Patel], while traveling with my dad. And then my dad bought me a motorcycle, so I started riding myself. From the time I entered med school in 1978 until I finished my residency in 1987, I made several trips following Kutchi migrant families and livestock. They leave their homeland in Kutch [district] during summer in search of grass and water to keep their livestock alive and walk across the state from the desert of Kutch all the way to central Gujarat until monsoon begins. Then they return, only to resume the journey next year. I would catch them along their journey, would talk to them, drink tea and eat millet crepes with them.
In 1984, between Dr. Patel’s medical school and residency, the Lions Club in his hometown, Ahmedabad, India, sponsored him and three buddies to document people and wildlife in Gujarat state. Traveling by motorcycle, the four friends stayed for free with local families by knocking on doors and explaining that they were medical students. Dr. Patel’s photographs were exhibited by the Lions Club of Ahmedabad and at India’s top art institution, the Lalit Kala gallery.
In the 3rd year of his internal-medicine residency in Bombay (now Mumbai), Dr. Patel approached a national newspaper, The Indian Express, for work. He was immediately sent on assignment to cover a cholera epidemic and filed his story and photographs the following day. He worked as a photojournalist and subeditor for a year.
Q: Among all your thousands of pictures, do you have a favorite?
A: There were two photos of Kutchi people that touched me. There was one photo of a lady. All of her worldly belongings were in the picture and a smile on her face showed that we don’t need so many things to be happy. The second photo is of an elderly lady shifting her water pan on her head to a younger family member. And a little girl looks up with a look of curiosity: Will I be doing this when I grow up? We seek so much materialistic happiness. But when you look at the curiosity, smiles, and happiness [in these photos], you realize we could have a lot of happiness in minimalism, as well.
Q: After you finished your residency in Ahmedabad, how did you get started in oncology?
A: In 1986, Ahmedabad City and Gujarat State did not have structured training programs in oncology, so I went to Bombay [Mumbai], where Dr. B.C. Mehta, a true legend and pioneer in India, had started hematology-oncology training. I was a post-doc research fellow with him for a little over a year but when I started seeing patients, I had to answer to myself, Am I doing everything I can to help these people? I saw that the U.K. had one of the best training programs in hem malignancy, so I started applying. Then something happened that was almost like a miracle.
In April 1992, Dr. Patel was working at the Institute of Kidney Diseases in Ahmedabad. One afternoon, just as the clinic was closing for siesta, a family brought in a young girl. She had drug-induced thrombocytopenia and needed an immediate transfusion. The father offered to sell his wedding ring to pay Dr. Patel if he would supervise the treatment and stay by the girl’s side. Dr. Patel told the man to keep his ring, then he remained in the office with the child. At 4 p.m., the office phone rang. It was Dr. H.K. Parikh, an eminent British physician who was wintering in India and needed to make a medical appointment for his wife. On a normal day, Dr. Patel would have missed the call.
“This is how I got to meet Dr. Parikh, out of the blue,” said Dr. Patel. “His wife came to the office for 6 weeks and after 6 weeks, he said, You’re a smart guy; you should come to England. That was in April. I sent a resume and all the usual paperwork. On July 16, 1992, at 2 in the morning, I got a call from the U.K. saying, Your job is confirmed. I’m going to fax your appointment through the Royal College of Physicians, and you’re coming to Manchester to work with us. I’d been sponsored by the Overseas Doctors Training Program.
“So, it turns out that if I’d declined to see that patient and declined to stay in my clinic that afternoon, if I’d declined to see this doctor’s wife, I would never have been in the U.K. And that opened up the doors for me. I like that story because I’ve found that standing up for people who do not have a voice, who do not have hope, always leads to what is destined for me.”
Q: After working as a registrar in the United Kingdom 4 years, you found yourself in the United States and, once again, had to train as an internist. What was new about U.S. oncology?
A: I took 3 years to get recertified in Jamaica Hospital in Queens, then became a fellow in hematology-oncology at the Thomas Jefferson in Philadelphia. My U.K. training was all based on hematological malignancy. In the United States, I shifted into solid tumors.
Q: You have a long history of advocating for affordable oncology at the community, state, and federal level, and you recently launched a disparities initiative in your center called NOLA (No One Left Alone). What was the trigger for NOLA?
A: In the spring of 2020, when we started seeing the COVID surge and the difference in mortality rate between the multiple races, at the same time I saw the AACR [American Association for Cancer Research] 2020 disparity report showing that 34% of cancer deaths are preventable – one in three – if we took care of disparities. The same year, the Community Oncology Alliance asked me to become the president. So, I felt that there is something herding me, leading me, to this position. Eighty percent of cancer patients are treated in community clinics like ours. It put the onus on me to do something.
I learned from Gandhi that I cannot depend on government, I cannot depend on the policy, I have to act myself.
I said, I would not worry about making money, I would rather lose funding on this. So, we started. I read 400+ papers; I spent over 1,000 hours reading about disparities. And I realized that it’s not complicated. There are five pillars to eliminate disparity: access to care for financial reasons, access to biomarker testing or precision medicine, access to social determinants of health, access to cancer screening, and trials. If we focus on these five, we can at least bring that number from 34% to 20%, if not lower.
So, we put that plan in place. I dedicated three employees whose only role is to ensure that not a single patient has to take financial burden from my practice. And we showed it’s doable.
This has now become my mission for the last quarter of my life.
In 2020, Dr. Patel published a book on dying well titled “Between Life and Death.” It’s framed as a series of his conversations with a former patient, Harry Falls. Harry wanted to understand death better, so Dr. Patel narrated five patient stories, drawing the threads together to help Harry face the inevitable. Dr. Patel now uses a similar approach to train clinicians on having meaningful end-of-life conversations with patients.
Q: Why did you feel the need to write a book about dying?
A: The more I’ve witnessed, the more I’m convinced that there are things that we don’t know about this process, which needs to be explored much more. However, I do feel that there’s a power within all of us to steer the process of leaving this world.
Before I sat down with Harry, I loved to counsel patients, but I didn’t have any structural ideas. It was Harry himself who told me that I now had a simple way to explain dying to a much larger audience.
Q: What is your secret for fitting everything into your life?
A: I’ll tell you, it’s very simple. If I put my soul, heart, mind, actions, and language on the one plane and don’t let my brain and conditioning influence my choices, then I live in the moment. Whenever I let my conditioned mind take all the decisions, those are crooked, because you know, we’re selfish creatures – we can use what we call the convenient lie to hide inconvenient truth. And I try not to do that. I mean, it’s been a journey. It didn’t come overnight. I learned. And I feel that over all these years, the only thing that rewarded me, that opened the door of where I am today, was pure, selfless process, whether it’s the act of talking, speaking, or doing.

In 2020, he published a book aimed at cancer specialists and their patients on how to die “with hope and dignity,” titled “Between Life and Death” (Penguin Random House India).
When Dr. Patel, the CEO of Carolina Blood and Cancer Care Associates in Rock Hill, S.C., became president of the Washington-based Community Oncology Alliance 2 years ago, he stepped into a leadership role in community oncology. As an advocate for health care payment reform on Capitol Hill, the South Carolina legislature, and within his own practice, Dr. Patel has long worked to eliminate disparities in U.S. cancer care.
This news organization spoke with Dr. Patel about his unusual career path.
Question: Your father had a great influence on you. Can you tell us more about him?
Answer: My dad was a hermit and a saint. He lost his dad when he was 4 years old and moved to the big city with his cousins. When he was 9 or so, he got a message saying that his mum was very ill. So, he and his cousin raised some money, got a doctor and one of those old, rugged jeeps, and they started driving to the village, but rains had destroyed the road. So, without penicillin, his mum died of pneumonia.
He felt that roads and doctor access were the two big factors that could have saved her life. He eventually became the Superintending Engineer for four districts in Gujarat State, building roads connecting every village, but he never gave up his simplistic, minimalist life.
When I was in elementary school, every other weekend my dad would literally dump me at the Mahatma Gandhi Ashram and come back in 2 hours. So, I’m looking at Gandhi’s cabinets, his pictures, reading about his life. So, my formative years were born in that.
Q: I read that you were intending to become an engineer and join the space race. How did your father nudge you toward medicine?
A: When I was 9 years old, my favorite movie hero died of cancer. To comfort me, my father inserted the idea into my brain: When you grow up, you can become a doctor to cure cancer. So, when I finished high school, I was 24th in the state and had an option to go to the space school in India. On the day when I was going for the interview, I could see tears in my father’s eyes, and he said, You know what, boy? I thought you’re going to become a doctor and cure cancer. So, to honor him, I went to med school instead.
Q: I understand that your father also triggered your interest in photography?
A: I started photographing Kutchi tribal people in 1977, after I bought a camera from a famous architect [Hasmukh Patel], while traveling with my dad. And then my dad bought me a motorcycle, so I started riding myself. From the time I entered med school in 1978 until I finished my residency in 1987, I made several trips following Kutchi migrant families and livestock. They leave their homeland in Kutch [district] during summer in search of grass and water to keep their livestock alive and walk across the state from the desert of Kutch all the way to central Gujarat until monsoon begins. Then they return, only to resume the journey next year. I would catch them along their journey, would talk to them, drink tea and eat millet crepes with them.
In 1984, between Dr. Patel’s medical school and residency, the Lions Club in his hometown, Ahmedabad, India, sponsored him and three buddies to document people and wildlife in Gujarat state. Traveling by motorcycle, the four friends stayed for free with local families by knocking on doors and explaining that they were medical students. Dr. Patel’s photographs were exhibited by the Lions Club of Ahmedabad and at India’s top art institution, the Lalit Kala gallery.
In the 3rd year of his internal-medicine residency in Bombay (now Mumbai), Dr. Patel approached a national newspaper, The Indian Express, for work. He was immediately sent on assignment to cover a cholera epidemic and filed his story and photographs the following day. He worked as a photojournalist and subeditor for a year.
Q: Among all your thousands of pictures, do you have a favorite?
A: There were two photos of Kutchi people that touched me. There was one photo of a lady. All of her worldly belongings were in the picture and a smile on her face showed that we don’t need so many things to be happy. The second photo is of an elderly lady shifting her water pan on her head to a younger family member. And a little girl looks up with a look of curiosity: Will I be doing this when I grow up? We seek so much materialistic happiness. But when you look at the curiosity, smiles, and happiness [in these photos], you realize we could have a lot of happiness in minimalism, as well.
Q: After you finished your residency in Ahmedabad, how did you get started in oncology?
A: In 1986, Ahmedabad City and Gujarat State did not have structured training programs in oncology, so I went to Bombay [Mumbai], where Dr. B.C. Mehta, a true legend and pioneer in India, had started hematology-oncology training. I was a post-doc research fellow with him for a little over a year but when I started seeing patients, I had to answer to myself, Am I doing everything I can to help these people? I saw that the U.K. had one of the best training programs in hem malignancy, so I started applying. Then something happened that was almost like a miracle.
In April 1992, Dr. Patel was working at the Institute of Kidney Diseases in Ahmedabad. One afternoon, just as the clinic was closing for siesta, a family brought in a young girl. She had drug-induced thrombocytopenia and needed an immediate transfusion. The father offered to sell his wedding ring to pay Dr. Patel if he would supervise the treatment and stay by the girl’s side. Dr. Patel told the man to keep his ring, then he remained in the office with the child. At 4 p.m., the office phone rang. It was Dr. H.K. Parikh, an eminent British physician who was wintering in India and needed to make a medical appointment for his wife. On a normal day, Dr. Patel would have missed the call.
“This is how I got to meet Dr. Parikh, out of the blue,” said Dr. Patel. “His wife came to the office for 6 weeks and after 6 weeks, he said, You’re a smart guy; you should come to England. That was in April. I sent a resume and all the usual paperwork. On July 16, 1992, at 2 in the morning, I got a call from the U.K. saying, Your job is confirmed. I’m going to fax your appointment through the Royal College of Physicians, and you’re coming to Manchester to work with us. I’d been sponsored by the Overseas Doctors Training Program.
“So, it turns out that if I’d declined to see that patient and declined to stay in my clinic that afternoon, if I’d declined to see this doctor’s wife, I would never have been in the U.K. And that opened up the doors for me. I like that story because I’ve found that standing up for people who do not have a voice, who do not have hope, always leads to what is destined for me.”
Q: After working as a registrar in the United Kingdom 4 years, you found yourself in the United States and, once again, had to train as an internist. What was new about U.S. oncology?
A: I took 3 years to get recertified in Jamaica Hospital in Queens, then became a fellow in hematology-oncology at the Thomas Jefferson in Philadelphia. My U.K. training was all based on hematological malignancy. In the United States, I shifted into solid tumors.
Q: You have a long history of advocating for affordable oncology at the community, state, and federal level, and you recently launched a disparities initiative in your center called NOLA (No One Left Alone). What was the trigger for NOLA?
A: In the spring of 2020, when we started seeing the COVID surge and the difference in mortality rate between the multiple races, at the same time I saw the AACR [American Association for Cancer Research] 2020 disparity report showing that 34% of cancer deaths are preventable – one in three – if we took care of disparities. The same year, the Community Oncology Alliance asked me to become the president. So, I felt that there is something herding me, leading me, to this position. Eighty percent of cancer patients are treated in community clinics like ours. It put the onus on me to do something.
I learned from Gandhi that I cannot depend on government, I cannot depend on the policy, I have to act myself.
I said, I would not worry about making money, I would rather lose funding on this. So, we started. I read 400+ papers; I spent over 1,000 hours reading about disparities. And I realized that it’s not complicated. There are five pillars to eliminate disparity: access to care for financial reasons, access to biomarker testing or precision medicine, access to social determinants of health, access to cancer screening, and trials. If we focus on these five, we can at least bring that number from 34% to 20%, if not lower.
So, we put that plan in place. I dedicated three employees whose only role is to ensure that not a single patient has to take financial burden from my practice. And we showed it’s doable.
This has now become my mission for the last quarter of my life.
In 2020, Dr. Patel published a book on dying well titled “Between Life and Death.” It’s framed as a series of his conversations with a former patient, Harry Falls. Harry wanted to understand death better, so Dr. Patel narrated five patient stories, drawing the threads together to help Harry face the inevitable. Dr. Patel now uses a similar approach to train clinicians on having meaningful end-of-life conversations with patients.
Q: Why did you feel the need to write a book about dying?
A: The more I’ve witnessed, the more I’m convinced that there are things that we don’t know about this process, which needs to be explored much more. However, I do feel that there’s a power within all of us to steer the process of leaving this world.
Before I sat down with Harry, I loved to counsel patients, but I didn’t have any structural ideas. It was Harry himself who told me that I now had a simple way to explain dying to a much larger audience.
Q: What is your secret for fitting everything into your life?
A: I’ll tell you, it’s very simple. If I put my soul, heart, mind, actions, and language on the one plane and don’t let my brain and conditioning influence my choices, then I live in the moment. Whenever I let my conditioned mind take all the decisions, those are crooked, because you know, we’re selfish creatures – we can use what we call the convenient lie to hide inconvenient truth. And I try not to do that. I mean, it’s been a journey. It didn’t come overnight. I learned. And I feel that over all these years, the only thing that rewarded me, that opened the door of where I am today, was pure, selfless process, whether it’s the act of talking, speaking, or doing.
Pandemic-related CRC screening delays affect older adults most
A 1- or 2-year delay in recommended colorectal cancer (CRC) screenings had little effect on most people’s risk of illness or death from cancer, provided they eventually got screened, according to a modeling study of the impact of pandemic-related screening delays.
Most patients whose screening was delayed still benefited through a reduction in risk of cancer or death, but that benefit was lower than it would have been had they been screened on time, particularly for 65-year-olds who hadn’t ever been screened for CRC.
Extending the upper ages for undergoing screening or substituting fecal immunochemical testing (FIT) for colonoscopies blunted some of this negative effect for 50-year-olds who had never been screened and for previously screened 60-year-olds, but those mitigation strategies weren’t as helpful for never-screened 65-year-olds, report Soham Sinha, MS, of Weill Cornell Medicine, and his colleagues.
Because older patients lose the most benefit from delayed CRC screenings, Mr. Sinha and his colleagues suggest, they should be prioritized when access is reduced.
The findings were published online in Gastroenterology.
Modeling the impact of missed screenings
CRC screenings dropped by as much as 82% at the start of the pandemic, Mr. Sinha and his co-authors note, and screening rates haven’t yet recovered as new COVID variants arise.
The researchers therefore sought to evaluate the potential clinical impact of screenings that were missed because of the pandemic on three groups of people who were at average risk of CRC: people who were 50 years old and had never been screened, people who were 65 and had never been screened, and people who had been screened by age 50 but were due for a colonoscopy screening at age 60.
They modeled the incidence and mortality of colorectal cancer for a 1-year and a 2-year delay in screening, compared with on-time screening with a colonoscopy or an annual FIT through age 75, or colonoscopy surveillance through age 80.
Among never-screened 50-year-olds, waiting a year or two to start colonoscopy screening resulted in a 69% reduction in colorectal cancer incidence instead of the 70% reduction that would have occurred with on-time screening. Similarly, the reduction in risk of death from delayed screening was 75% instead of 76% with on-time screening.
A 1- or 2-year delay in starting FIT screening in this group led to a reduction in the benefit of lower risk by one percentage point: Patients had a 57% lower risk of cancer from a 1-year screening delay and a 56% reduction in risk from a 2-year delay, compared with a 58% reduction in risk without any delays. In terms of mortality, benefit fell by one absolute percentage point for each year of delay.
Restoring the benefits of screening
The most effective way to mitigate each of those lost percentage points from colonoscopy delays was to combine two rescue strategies: using FIT screening instead of colonoscopy when colonoscopy access was reduced and extending the upper ages of colonoscopy screening to age 76-77 and colonoscopy surveillance to age 81-82.
Solely extending the ages for undergoing screening and surveillance was more effective than solely substituting FIT screening for colonoscopies. To offset the impact of an FIT delay, extending the upper age of the screening or surveillance period was effective.
The negative effect of delayed colonoscopy screenings was greater for never-screened 65-year-olds, whose reduction in risk of developing CRC fell to 53%-54%, rather than the 66% reduction in risk they would have had with on-time screening. The reduction in risk of mortality from CRC was 60% instead of 74% if screenings were delayed instead of occurring on time.
“Starting at age 65 afforded individuals two lifetime colonoscopies, as opposed to one at age 66 or later, given that colorectal screening ended at age 75,” the authors write. “Rescue strategies decreased but did not negate the impact of pandemic-related colorectal screening delays.”
For never-screened 65-year-olds who experienced delays in FIT, undergoing screening 1 year late equated to a 41% reduction in cancer risk, and undergoing screening 2 years late resulted in a 38% reduction, compared with a 44% reduction with on-time FIT screening. The reduction in mortality fell from 60% with on-time screening to 57% with a 1-year delay and 54% with a 2-year delay. Though extending the upper age limited reduced this negative effect, it did not eliminate it.
The researchers found that delaying screening by 1 or 2 years among 60-year-olds who had had a colonoscopy at age 50 only modestly reduced the benefit of reduced risk of CRC or death.
“Rescue strategies mitigated or negated impact from colorectal screening delays and included FIT-based screening when colonoscopy was unavailable, with or without extended screening through ages 75 or 76,” the authors report.
One limitation of the study was its lack of cost-effectiveness calculations, which made it impossible to evaluate the economic implications of either the delays in screening or the proposed mitigation strategies.
“Our work suggests that among the 20% of the U.S. population aged 50-75 who are unscreened for colorectal cancer, older adults would experience the most clinical benefit from colorectal cancer screening if resources were limited during the COVID-19 pandemic,” the authors write.
Younger people who hadn’t yet been screened and those who had been screened at least once with a colonoscopy would not experience as dramatic a reduction in benefit once they underwent screening, they conclude.

Genetic tests create treatment opportunities and confusion for breast cancer patients
The past decade has witnessed a rapid expansion of genetic tests, including new instruments to inform patients who have been diagnosed with breast cancer about the risk of recurrence and to guide their treatment.
Patients are sometimes left paying out-of-pocket for exams that are not yet the standard of care, and even the most up-to-date oncologists may be uncertain how to incorporate the flood of new information into what used to be standard treatment protocols.
A quarter-century ago, Myriad Genetics introduced the first breast cancer genetic test for BRCA mutations, two genes associated with a substantially elevated risk of getting breast cancer, opening the door to a new era in genetic testing. BRCA1 and BRCA2 mutations account for as many as half of all hereditary breast cancers, and people with a problematic mutation on one of those genes have a 45%-72% chance of developing breast cancer during their lifetimes. They may also be at higher risk for ovarian and other cancers than people without harmful BRCA mutations.
But the clinical significance is murkier for many other genetic tests.
Testing for BRCA1 and BRCA2 genes used to cost thousands of dollars. Now, for a fraction of that, doctors can order multigene test panels from commercial labs that look for mutations in dozens of genes. Some direct-to-consumer companies offer screening panels for a few hundred dollars, though their reliability varies.
When Jen Carbary was diagnosed with breast cancer in 2017 at age 44, genetic testing identified a mutation in a gene called PALB2 that significantly increases the risk of developing breast cancer. Guidelines suggest that breast cancer patients with a PALB2 mutation, much like those with BRCA1 and BRCA2 mutations, consider having a mastectomy to reduce the chance of a breast cancer recurrence.
“I wish genetic testing was the standard of care,” said Ms. Carbary, who owed nothing for the test because her insurer covered the cost.
Ms. Carbary, who lives in Sterling Heights, Mich., said the test results affirmed the decision she had already made to have a double mastectomy and provided important information for family members, including her 21-year-old daughter and 18-year-old son, who will likely be tested in their mid-20s or early 30s.
But some breast cancer experts are concerned that widespread testing may also identify genetic mutations whose impact is unclear, creating anxiety and leading to further testing and to treatment of questionable value that could raise costs for the health care system.
It can also confuse patients.
“It happens a lot, that patients find their way to us after getting confusing results elsewhere,” said Mark Robson, MD, chief of the breast medicine service at Memorial Sloan Kettering Cancer Center, New York. Robson said the cancer center has a clinical genetics service, staffed by doctors and genetic counselors, that helps people make decisions about how to manage genetic testing results.
For people diagnosed with breast cancer, many professional groups, including the influential National Comprehensive Cancer Network, recommend limiting testing to certain people, including those with high-risk factors, such as a family history of breast cancer; those who are 45 or younger when they’re diagnosed; and those with Ashkenazi Jewish ancestry.
But in 2019, the American Society of Breast Surgeons recommended a different approach: Offer genetic testing to all patients who are diagnosed with or have a personal history of breast cancer. The recommendation was controversial.
“The NCCN guidelines [cover] most of the women who needed testing, but we wanted to get them all,” said Eric Manahan, MD, a general surgeon in Dalton, Georgia, and a member of the surgeons group’s board of directors.
Mutations on other genes that are associated with breast cancer are much less common than BRCA1 and BRCA2 mutations and generally don’t increase the risk of developing breast cancer as much. The cancer-causing impact of these genes may be less clear than that of the BRCA genes, which have been tested for since the mid-1990s.
And the appropriate response to the less common mutations – whether to consider a risk-reducing mastectomy or stepped-up screening – is often unclear.
“Things get sloppier and sloppier when you look at other genes,” said Steven Katz, MD, MPH, a professor of medicine and health management and policy at the University of Michigan. “The risks tend to be lower for different cancers, and less certain and more variable. You might walk away wondering: ‘Why’d I have to know that?’ ”
After people are diagnosed with breast cancer, genetic testing can help inform their decisions about the types of surgery to pursue – for example, a high risk of recurrence or a new breast cancer might persuade some to opt for more extensive surgery, such as a double mastectomy. Testing can also provide important information to family members about their potential cancer risk.
(This type of “germline” genetic testing, as it’s called, looks at mutations in the genes that people inherit from their parents. It is different from genomic tumor tests that look at specific genes or proteins in the cancer cells and can help doctors understand the rate at which the cancer cells are dividing, for example, and the likelihood of a cancer recurrence.)
Increasingly, germline genetic testing can also help guide other treatment decisions. Some patients with metastatic breast cancer who have BRCA1 or BRCA2 mutations may be good candidates for poly (ADP-ribose) polymerase inhibitors, cancer drugs that target tumors with mutations in those genes.
But genetic testing that uncovers inherited mutations in many other genes yields less clearly actionable information, even though positive results may alarm people.
At Memorial Sloan Kettering, cancer specialists focus on “therapeutic actionability,” said Dr. Robson. Will testing help someone decide whether she should get a double mastectomy or provide other important guidance? “A policy of testing everyone will identify very few additional BRCA breast mutations but will cost a lot.”
As a result, doctors are debating how best to deploy and incorporate new genetic knowledge. Insurers are trying to figure out which to pay for.
There is both underuse of tests that science says are relevant and overuse of tests that experts say provide information that can’t be interpreted with any scientific certainty.
The result may be confusion for patients newly diagnosed with breast cancer as they confront the expense of genetic tests and sometimes little guidance on the proper treatment.
Some doctors say the first step is to make sure that the small group of people who would clearly benefit are getting the genetic tests whose meaning is clearly understood. Only 15% of breast cancer patients who met select NCCN testing guidelines for inherited cancer received genetic testing, according to a 2017 study that examined data from a national household health survey between 2005 and 2015.
“I would argue that our focus needs to be on the people who are at high risk for breast cancer that aren’t even identified yet,” said Tuya Pal, MD, associate director for cancer health disparities at Vanderbilt-Ingram Cancer Center and vice chair of the NCCN guidelines panel for genetic/familial high-risk assessment of breast, ovarian, and pancreatic cancers.
Patients may fall through the cracks because no one tells them they should be tested. In one analysis, 56% of high-risk breast cancer patients who didn’t get genetic testing said their doctors didn’t recommend it.
Even if doctors recommend genetic testing, they may lack the expertise to determine which tests people need and how to interpret the results. That’s the role of genetic counselors, but their ranks are stretched thin.
The consequences can be serious. In a study of 666 breast cancer patients who received genetic testing, half of those at average risk for inherited cancer got double mastectomies based on test results that found “variants of uncertain significance,” which aren’t clinically actionable. As many as half of surgeons reported managing such patients the same way as those with cancer-causing mutations.
“The bulk of our research would say that there is still room for improvement in terms of clinicians getting the understanding they need,” said Allison Kurian, MD, director of the women’s clinical cancer genetics program at Stanford (Calif.) University and a coauthor of the study.

The past decade has witnessed a rapid expansion of genetic tests, including new instruments to inform patients who have been diagnosed with breast cancer about the risk of recurrence and to guide their treatment.
Patients are sometimes left paying out-of-pocket for exams that are not yet the standard of care, and even the most up-to-date oncologists may be uncertain how to incorporate the flood of new information into what used to be standard treatment protocols.
A quarter-century ago, Myriad Genetics introduced the first breast cancer genetic test for BRCA mutations, two genes associated with a substantially elevated risk of getting breast cancer, opening the door to a new era in genetic testing. BRCA1 and BRCA2 mutations account for as many as half of all hereditary breast cancers, and people with a problematic mutation on one of those genes have a 45%-72% chance of developing breast cancer during their lifetimes. They may also be at higher risk for ovarian and other cancers than people without harmful BRCA mutations.
But the clinical significance is murkier for many other genetic tests.
Testing for BRCA1 and BRCA2 genes used to cost thousands of dollars. Now, for a fraction of that, doctors can order multigene test panels from commercial labs that look for mutations in dozens of genes. Some direct-to-consumer companies offer screening panels for a few hundred dollars, though their reliability varies.
When Jen Carbary was diagnosed with breast cancer in 2017 at age 44, genetic testing identified a mutation in a gene called PALB2 that significantly increases the risk of developing breast cancer. Guidelines suggest that breast cancer patients with a PALB2 mutation, much like those with BRCA1 and BRCA2 mutations, consider having a mastectomy to reduce the chance of a breast cancer recurrence.
“I wish genetic testing was the standard of care,” said Ms. Carbary, who owed nothing for the test because her insurer covered the cost.
Ms. Carbary, who lives in Sterling Heights, Mich., said the test results affirmed the decision she had already made to have a double mastectomy and provided important information for family members, including her 21-year-old daughter and 18-year-old son, who will likely be tested in their mid-20s or early 30s.
But some breast cancer experts are concerned that widespread testing may also identify genetic mutations whose impact is unclear, creating anxiety and leading to further testing and to treatment of questionable value that could raise costs for the health care system.
It can also confuse patients.
“It happens a lot, that patients find their way to us after getting confusing results elsewhere,” said Mark Robson, MD, chief of the breast medicine service at Memorial Sloan Kettering Cancer Center, New York. Robson said the cancer center has a clinical genetics service, staffed by doctors and genetic counselors, that helps people make decisions about how to manage genetic testing results.
For people diagnosed with breast cancer, many professional groups, including the influential National Comprehensive Cancer Network, recommend limiting testing to certain people, including those with high-risk factors, such as a family history of breast cancer; those who are 45 or younger when they’re diagnosed; and those with Ashkenazi Jewish ancestry.
But in 2019, the American Society of Breast Surgeons recommended a different approach: Offer genetic testing to all patients who are diagnosed with or have a personal history of breast cancer. The recommendation was controversial.
“The NCCN guidelines [cover] most of the women who needed testing, but we wanted to get them all,” said Eric Manahan, MD, a general surgeon in Dalton, Georgia, and a member of the surgeons group’s board of directors.
Mutations on other genes that are associated with breast cancer are much less common than BRCA1 and BRCA2 mutations and generally don’t increase the risk of developing breast cancer as much. The cancer-causing impact of these genes may be less clear than that of the BRCA genes, which have been tested for since the mid-1990s.
And the appropriate response to the less common mutations – whether to consider a risk-reducing mastectomy or stepped-up screening – is often unclear.
“Things get sloppier and sloppier when you look at other genes,” said Steven Katz, MD, MPH, a professor of medicine and health management and policy at the University of Michigan. “The risks tend to be lower for different cancers, and less certain and more variable. You might walk away wondering: ‘Why’d I have to know that?’ ”
After people are diagnosed with breast cancer, genetic testing can help inform their decisions about the types of surgery to pursue – for example, a high risk of recurrence or a new breast cancer might persuade some to opt for more extensive surgery, such as a double mastectomy. Testing can also provide important information to family members about their potential cancer risk.
(This type of “germline” genetic testing, as it’s called, looks at mutations in the genes that people inherit from their parents. It is different from genomic tumor tests that look at specific genes or proteins in the cancer cells and can help doctors understand the rate at which the cancer cells are dividing, for example, and the likelihood of a cancer recurrence.)
Increasingly, germline genetic testing can also help guide other treatment decisions. Some patients with metastatic breast cancer who have BRCA1 or BRCA2 mutations may be good candidates for poly (ADP-ribose) polymerase inhibitors, cancer drugs that target tumors with mutations in those genes.
But genetic testing that uncovers inherited mutations in many other genes yields less clearly actionable information, even though positive results may alarm people.
At Memorial Sloan Kettering, cancer specialists focus on “therapeutic actionability,” said Dr. Robson. Will testing help someone decide whether she should get a double mastectomy or provide other important guidance? “A policy of testing everyone will identify very few additional BRCA breast mutations but will cost a lot.”
As a result, doctors are debating how best to deploy and incorporate new genetic knowledge. Insurers are trying to figure out which to pay for.
There is both underuse of tests that science says are relevant and overuse of tests that experts say provide information that can’t be interpreted with any scientific certainty.
The result may be confusion for patients newly diagnosed with breast cancer as they confront the expense of genetic tests and sometimes little guidance on the proper treatment.

Experts sound alarm on ruling threatening preventive cancer care
In a statement, the groups highlighted that the decision “would result in a return to financial and other barriers proven to discourage Americans from obtaining lifesaving, preventive care.”
The ruling, issued earlier in September by a federal district judge in Texas, essentially says that the U.S. Preventive Services Task Force has no authority to determine which preventive care services must be fully covered by insurance companies – an ability granted by the Affordable Care Act (ACA).
Judge Reed O’Connor ruled that the method of appointing officers to the USPSTF is unconstitutional, which means the task force’s recommendations for no-cost preventive health care may no longer be guaranteed under the ACA for millions of insured Americans.
The judgment, however, is not yet final, and individuals still have access to these preventive services. The judge must first make the scope of the ruling clear, and the decision will likely be appealed. In addition, the decision does not affect the authority of two other entities that make recommendations about vaccinations and preventive care for infants, children, and adolescents.
But experts are concerned that the ruling will force some individuals to pay out of pocket for preventive cancer screenings and other care that would otherwise have been fully covered by insurance.
After the ruling, a group of 26 patient groups, including the American Cancer Society Cancer Action Network and the Leukemia and Lymphoma Society, took a stand.
In a statement, the groups highlighted that “access to preventive health care can prevent both disease and early death.” Under the ACA, more than 150 million Americans have benefited from expanded access to these services, and research reveals that high-quality coverage – which includes preventive services – improves health, reduces health disparities, and lowers health care costs. “This ruling directly threatens these benefits,” they explained.
Lisa Lacasse, MBA, president of ACS CAN, agreed that the ruling “threatens to erode more than a decade of progress reducing cancer deaths and suffering.”
In a statement, the ACS CAN urged the government to “swiftly appeal” the decision.
“We cannot risk returning to a system wherein every individual has to interpret their complex insurance plans to determine if a recommended mammogram will be covered or to determine how much their colonoscopy may cost,” Ms. Lacasse told this news organization.
For now, Ms. Lacasse urged patients and providers to remember that no changes to coverage requirements will occur while litigation continues.
“All preventive services required under the Affordable Care Act remain in place with no cost sharing for enrollees,” she said. “ACS CAN will continue to support and advocate for coverage of preventive services at no cost sharing.”

Novel blood test for early-stage liver cancer shows promise
, increasing the likelihood of potentially curative therapy and improved patient prognosis.
HCC accounts for the majority of primary liver cancers and mainly occurs in patients with cirrhosis or chronic hepatitis B virus infection. The prognosis of HCC is poor, largely owing to advanced disease stage at diagnosis.
The current guidelines recommend surveillance with twice-yearly liver ultrasound, with or without serum alpha-fetoprotein, for patients at risk for HCC, although the diagnostic performance is suboptimal.
The new “liquid biopsy” uses HCC-associated extracellular vesicles (EVs) to establish an HCC EV ECG score for distinguishing patients with early-stage HCC from at-risk controls with cirrhosis from a 400-mcL plasma sample.
“We’re the first team looking at extracellular vesicles as a detection biomarker for early-stage liver cancer, and our study showed it had outstanding performance,” study investigator Ju Dong Yang, MD, with Cedars-Sinai Medical Center, Los Angeles, said in a news release.
The study was published online in Hepatology.
In a phase 2 biomarker (case-control) study, the investigators tested their blood test in a training cohort of 106 individuals (45 patients with treatment-naive early-stage HCC and 61 with cirrhosis) and an independent validation cohort with 72 participants (35 patients with treatment-naive early-stage HCC and 37 with cirrhosis).
The HCC EV ECG score had “excellent accuracy” for discriminating between HCC and cirrhosis, with an area under the receiver operating characteristic curve (AUROC) of 0.95 and 0.93 in the training and validation cohorts, respectively, they report.
The diagnostic performance “remained excellent” among the subpopulations of HCC etiology and those with tumors within the Milan criteria.
Adding the serum alpha-fetoprotein level to the HCC EV ECG score did not improve its performance.
The researchers say that further validation of the blood test in a larger phase 2 study and a subsequent phase 3 study are needed to confirm its utility in clinical settings.
“We are planning on doing larger-scale studies to further validate this test and bring it into routine clinical practice here – and globally,” Dr. Yang said.
“In addition to its excellent performance, this marker has the advantages of being user friendly, cost efficient, and having a fast turnaround time – within 6 hours from sample collection to result,” Dan Theodorescu, MD, PhD, director of Cedars-Sinai Cancer, who is not an author on the study, said in the news release.
“Once this marker has been validated in subsequent studies, it can be easily adopted by existing PCR [polymerase chain reaction] facilities,” Dr. Theodorescu added.
The study was supported by an American College of Gastroenterology Junior Faculty Development Award, a Department of Defense Peer Reviewed Cancer Research Program Career Development Award, and the National Institutes of Health. Dr. Yang provides a consulting service for Exact Sciences, Gilead Sciences, and Eisai. Dr. Theodorescu reports no relevant financial relationships.

Atezolizumab doubles survival of NSCLC patients with poor performance status
PARIS – Patients with untreated non–small cell lung cancer (NSCLC) who could not withstand the rigors of platinum-based chemotherapy regimens had significantly better overall survival when treated with the immune checkpoint inhibitor atezolizumab (Tecentriq), compared with their counterparts treated with either vinorelbine or gemcitabine in a phase 3 randomized trial.
Among 353 patients with treatment-naive stage 3B to 4 NSCLC who were not candidates for platinum-based chemotherapy because of poor performance status (PS), advanced age, or significant comorbidities, the median overall survival (OS) was 10.3 months for patients treated with atezolizumab vs. 9.2 months for patients assigned to receive the investigator’s choice of single-agent chemotherapy.
This difference translated into a hazard ratio for death with atezolizumab of 0.78 (P = .028), Siow Ming Lee, MD, PhD, of University College London, reported at the ESMO Congress.
The 2-year OS rate with atezolizumab was 24.3%, compared with 12.4% for single-agent chemotherapy.
“When I saw the data, I was amazed. One of four patients survived for 2 years!” he said in an interview.
, those with Eastern Cooperative Oncology Group PS scores of 2 or greater, or who have substantial comorbidities that preclude their ability to receive platinum doublet or single platinum agent chemotherapy, he said.
Invited discussant Natasha Leighl, MD, MMSc, of the Princess Margaret Cancer Center, Toronto, called the study “really extraordinary. This study enrolls patients that historically are excluded or underrepresented in trials, and yet really represent the majority of patients that we diagnose and treat around the world.”
Excluded from clinical trials
“Cancer chemotherapy has changed the treatment landscape for the metastatic NSCLC population, but these treatments are mainly recommended for fit patients,” Dr. Lee said during his presentation of the data in a presidential symposium.
First-line pivotal trials for lung cancer patients comparing either single-agent immunotherapy or an immunotherapy/chemotherapy combination have all been conducted in fit patients, with ECOG PS of 0 or 1, he noted.
“In reality, we still have a large population of unfit NSCLC patients, of at least 40%, many of which we cannot treat with standard platinum chemotherapy. There are many elderly patients with poor performance status, and the elderly with many comorbidities, and they are frequently on many drug medications, which we see frequently in our clinic,” he said.
Study details
To see whether immunotherapy could improve outcomes for unfit patients, investigators designed the IPSOS trial, a phase 3 multicenter open-label study of efficacy, safety, and patient-reported outcomes with atezolizumab compared with single-agent chemotherapy.
Patients from 23 centers in North America, South America, Europe, and Asia who were ineligible for platinum-based chemotherapy because of ECOG performance status of 2 or 3, or who were aged 70 or older with performance status 0 or 1 but with multiple comorbidities or other contraindications to platinum were stratified by histology, programmed death-ligand-1 (PD-L1) expression, and brain metastases, and were then randomly assigned to receive either atezolizumab 1,200 mg intravenously every 3 weeks (302 patients), or to investigator’s choice of either vinorelbine delivered orally or intravenously, according to local practice, or intravenous gemcitabine given intravenously per local practice (151 patients).
As noted before, overall survival, the primary endpoint, was significantly better with atezolizumab, translating into a 22% reduction in risk of death compared with chemotherapy.
The 1-year OS rates were 43.7% with atezolizumab vs. 36.6% with chemotherapy, and the 2-year rates were 24.3% vs. 12.4%, respectively.
A subgroup analysis showed trends toward better benefit for immunotherapy regardless of age, sex, race, performance status, history of tobacco use, tumor histology, stage, presence of liver metastases, number of metastatic sites, or PD-L1 expression levels. The benefit of atezolizumab was also significantly better among patients without brain metastases.
The median duration of response was 14 months with ateziluzmab vs. 7.8 months with chemotherapy. Respective objective response rates were 16.9% vs. 15.5%. Median progression-free survival, a secondary endpoint, was 4.2 months with atezolizumab and 4 months with chemotherapy, a difference that was not statistically significant. Median treatment duration was 3.5 months with atezolizumab, 2.3 months with gemcitabine, and 1.8 months with vinorelbine. Treatment-related adverse events of any grade occurred in 57% of patients on immunotherapy vs. 80.3% of those on chemotherapy. Grade 3 or 4 adverse events related to therapy occurred in 16.3% vs. 33.3%, respectively. About 13% of patients in each arm had an adverse event leading to drug discontinuation. There were three treatment-related deaths among patients on atezolizumab, and four among patients on chemotherapy. Compared with chemotherapy, atezolizumab was associated with stabilizing of health-related quality-of-life domains of functioning, and significant improvement in delaying the time to deterioration of chest pain.
Age is not prognostic
“I think it’s important though to remember that in this study there are very distinct populations of patients. Poor performance status and comorbidities are prognostic, but age is not,” Dr. Leighl said in her discussion.
“In terms of current standards, performance status 3 patients are currently recommended to have best supportive care unless a targeted therapy is available for them, and while PS 2 patients have been excluded from checkpoint inhibitor trials, we treat most of these patients the same way. In this study in particular, patients had to be ineligible for platinum doublet therapy, but of course this definition was subjective,” she said.
She also commented that “if we’re now going to treat everyone with atezolizumab, I think the budget impact of this is going to be huge.”
It will be important to identify more clearly those patients aged 80 and older who might benefit from atezolizumab in this setting by better incorporating biomarkers such as PD-L1 levels to determine who can benefit from therapy and who might be spared the necessity of coming into the hospital or clinic for regular intravenous infusions, she added.
The study was supported by F. Hoffman-La Roche. Dr. Lee disclosed research funding from the company to his institution. Dr. Leighl disclosed institutional grant funding and personal fees from Roche and others.
PARIS – Patients with untreated non–small cell lung cancer (NSCLC) who could not withstand the rigors of platinum-based chemotherapy regimens had significantly better overall survival when treated with the immune checkpoint inhibitor atezolizumab (Tecentriq), compared with their counterparts treated with either vinorelbine or gemcitabine in a phase 3 randomized trial.
Among 353 patients with treatment-naive stage 3B to 4 NSCLC who were not candidates for platinum-based chemotherapy because of poor performance status (PS), advanced age, or significant comorbidities, the median overall survival (OS) was 10.3 months for patients treated with atezolizumab vs. 9.2 months for patients assigned to receive the investigator’s choice of single-agent chemotherapy.

AT ESMO CONGRESS 2022
A farewell to arms? Drug approvals based on single-arm trials can be flawed
PARIS – with results that should only be used, under certain conditions, for accelerated approvals that should then be followed by confirmatory studies.
In fact, many drugs approved over the last decade based solely on data from single-arm trials have been subsequently withdrawn when put through the rigors of a head-to-head randomized controlled trial, according to Bishal Gyawali, MD, PhD, from the department of oncology at Queen’s University, Kingston, Ont.
“Single-arm trials are not meant to provide confirmatory evidence sufficient for approval; However, that ship has sailed, and we have several drugs that are approved on the basis of single-arm trials, but we need to make sure that those approvals are accelerated or conditional approvals, not regular approval,” he said in a presentation included in a special session on drug approvals at the European Society for Medical Oncology Congress.
“We should not allow premature regular approval based on single-arm trials, because once a drug gets conditional approval, access is not an issue. Patients will have access to the drug anyway, but we should ensure that robust evidence follows, and long-term follow-up data are needed to develop confidence in the efficacy outcomes that are seen in single-arm trials,” he said.
In many cases, single-arm trials are large enough or of long enough duration that investigators could have reasonably performed a randomized controlled trial (RCT) in the first place, Dr. Gyawali added.
Why do single-arm trials?
The term “single-arm registration trial” is something of an oxymoron, he said, noting that the purpose of such trials should be whether to take the drug to a phase 3, randomized trial. But as authors of a 2019 study in JAMA Network Open showed, of a sample of phase 3 RCTs, 42% did not have a prior phase 2 trial, and 28% had a negative phase 2 trial. Single-arm trials may be acceptable for conditional drug approvals if all of the following conditions are met:
- A RCT is not possible because the disease is rare or randomization would be unethical.
- The safety of the drug is established and its potential benefits outweigh its risks.
- The drug is associated with a high and durable overall or objective response rate.
- The mechanism of action is supported by a strong scientific rationale, and if the drug may meet an unmet medical need.
Survival endpoints won’t do
Efficacy endpoints typically used in RCTs, such as progression-free survival (PFS) and overall survival (OS) can be misleading because they may be a result of the natural history of the disease and not the drug being tested, whereas ORRs are almost certainly reflective of the action of the drug itself, because spontaneous tumor regression is a rare phenomenon, Dr. Gyawali said.
He cautioned, however, that the ORR of placebo is not zero percent. For example in a 2018 study of sorafenib (Nexavar) versus placebo for advanced or refractory desmoid tumors, the ORR with the active drug was 33%, and the ORR for placebo was 20%.
It’s also open to question, he said, what constitutes an acceptably high ORR and duration of response, pointing to Food and Drug Administration accelerated approval of an indication for nivolumab (Opdivo) for treatment of patients with hepatocellular carcinoma (HCC) that had progressed on sorafenib. In the single-arm trial used as the basis for approval, the ORRs as assessed by an independent central review committee blinded to the results was 14.3%.
“So, nivolumab in hepatocellular cancer was approved on the basis of a response rate lower than that of placebo, albeit in a different tumor. But the point I’m trying to show here is we don’t have a good definition of what is a good response rate,” he said.
In July 2021, Bristol-Myers Squibb voluntarily withdrew the HCC indication for nivolumab, following negative results of the CheckMate 459 trial and a 5-4 vote against continuing the accelerated approval.
On second thought ...
Citing data compiled by Nathan I. Cherny, MD, from Shaare Zedek Medical Center, Jerusalem, Dr. Gyawali noted that 58 of 161 FDA approvals from 2017 to 2021 of drugs for adult solid tumors were based on single-arm trials. Of the 58 drugs, 39 received accelerated approvals, and 19 received regular approvals; of the 39 that received accelerated approvals, 4 were subsequently withdrawn, 8 were converted to regular approvals, and the remainder continued as accelerated approvals.
Interestingly, the median response rate among all the drugs was 40%, and did not differ between the type of approval received, suggesting that response rates are not predictive of whether a drug will receive a conditional or full-fledged go-ahead.
What’s rare and safe?
The definition of a rare disease in the United States is one that affects fewer than 40,000 per year, and in Europe it’s an incidence rate of less than 6 per 100,000 population, Dr. Gyawali noted. But he argued that even non–small cell lung cancer, the most common form of cancer in the world, could be considered rare if it is broken down into subtypes that are treated according to specific mutations that may occur in a relatively small number of patients.
He also noted that a specific drug’s safety, one of the most important criteria for granting approval to a drug based on a single-arm trial, can be difficult to judge without adequate controls for comparison.
Cherry-picking patients
Winette van der Graaf, MD, president of the European Organization for the Research and Treatment of Cancer, who attended the session where Dr. Gyawali’s presentation was played, said in an interview that clinicians should cast a critical eye on how trials are designed and conducted, including patient selection and choice of endpoints.
“One of the most obvious things to be concerned about is that we’re still having patients with good performance status enrolled, mostly PS 0 or 1, so how representative are these clinical trials for the patients we see in front of us on a daily basis?” she said.
“The other question is radiological endpoints, which we focus on with OS and PFS are most important for patients, especially if you consider that if patients may have asymptomatic disease, and we are only treating them with potentially toxic medication, what are we doing for them? Median overall survival when you look at all of these trials is only 4 months, so we really need to take into account how we affect patients in clinical trials,” she added.
Dr. van der Graaf emphasized that clinical trial investigators need to more routinely incorporate quality of life measures and other patient-reported outcomes in clinical trial results to help regulators and clinicians in practice get a better sense of the true clinical benefit of a new drug.
Dr. Gyawali did not disclose a funding source for his presentation. He reported consulting fees from Vivio Health and research grants from the American Society of Clinical Oncology. Dr. van der Graaf reported no conflicts of interest.

It’s also open to question, he said, what constitutes an acceptably high ORR and duration of response, pointing to Food and Drug Administration accelerated approval of an indication for nivolumab (Opdivo) for treatment of patients with hepatocellular carcinoma (HCC) that had progressed on sorafenib. In the single-arm trial used as the basis for approval, the ORRs as assessed by an independent central review committee blinded to the results was 14.3%.
“So, nivolumab in hepatocellular cancer was approved on the basis of a response rate lower than that of placebo, albeit in a different tumor. But the point I’m trying to show here is we don’t have a good definition of what is a good response rate,” he said.
In July 2021, Bristol-Myers Squibb voluntarily withdrew the HCC indication for nivolumab, following negative results of the CheckMate 459 trial and a 5-4 vote against continuing the accelerated approval.
On second thought ...
Citing data compiled by Nathan I. Cherny, MD, from Shaare Zedek Medical Center, Jerusalem, Dr. Gyawali noted that 58 of 161 FDA approvals from 2017 to 2021 of drugs for adult solid tumors were based on single-arm trials. Of the 58 drugs, 39 received accelerated approvals, and 19 received regular approvals; of the 39 that received accelerated approvals, 4 were subsequently withdrawn, 8 were converted to regular approvals, and the remainder continued as accelerated approvals.
Interestingly, the median response rate among all the drugs was 40%, and did not differ between the type of approval received, suggesting that response rates are not predictive of whether a drug will receive a conditional or full-fledged go-ahead.
What’s rare and safe?
The definition of a rare disease in the United States is one that affects fewer than 40,000 per year, and in Europe it’s an incidence rate of less than 6 per 100,000 population, Dr. Gyawali noted. But he argued that even non–small cell lung cancer, the most common form of cancer in the world, could be considered rare if it is broken down into subtypes that are treated according to specific mutations that may occur in a relatively small number of patients.
He also noted that a specific drug’s safety, one of the most important criteria for granting approval to a drug based on a single-arm trial, can be difficult to judge without adequate controls for comparison.
Cherry-picking patients
Winette van der Graaf, MD, president of the European Organization for the Research and Treatment of Cancer, who attended the session where Dr. Gyawali’s presentation was played, said in an interview that clinicians should cast a critical eye on how trials are designed and conducted, including patient selection and choice of endpoints.
“One of the most obvious things to be concerned about is that we’re still having patients with good performance status enrolled, mostly PS 0 or 1, so how representative are these clinical trials for the patients we see in front of us on a daily basis?” she said.
“The other question is radiological endpoints, which we focus on with OS and PFS are most important for patients, especially if you consider that if patients may have asymptomatic disease, and we are only treating them with potentially toxic medication, what are we doing for them? Median overall survival when you look at all of these trials is only 4 months, so we really need to take into account how we affect patients in clinical trials,” she added.
Dr. van der Graaf emphasized that clinical trial investigators need to more routinely incorporate quality of life measures and other patient-reported outcomes in clinical trial results to help regulators and clinicians in practice get a better sense of the true clinical benefit of a new drug.
Dr. Gyawali did not disclose a funding source for his presentation. He reported consulting fees from Vivio Health and research grants from the American Society of Clinical Oncology. Dr. van der Graaf reported no conflicts of interest.
