With Age, Many Cells Contain Cancerous Mutations That Never Develop Into Cancer

Encouraging non-cancerous mutations that compete for resources with cancerous mutations is a novel approach for curing some cancers, but there are many other novel and plausible approaches. Cancer is a complicated and diverse disease; maybe we will eventually see “cancer” as many different diseases. We have too much uncertainty to mandate one centrally planned approach. Plus citizens have the right to keep the money they earn and to choose how to spend that money. We should keep taxation and regulations low so that diverse funders can follow their judgements to fund diverse approaches. [Most of what I just wrote, I also wrote for an earlier entry.]

(p. D3) Cancer is a disease of mutations. Tumor cells are riddled with genetic mutations not found in healthy cells. Scientists estimate that it takes five to 10 key mutations for a healthy cell to become cancerous.

Some of these mutations can be caused by assaults from the environment, such as ultraviolet rays and cigarette smoke. Others arise from harmful molecules produced by the cells themselves. In recent years, researchers have begun taking a closer look at these mutations, to try to understand how they arise in healthy cells, and what causes these cells to later erupt into full-blown cancer.

The research has produced some major surprises. For instance, it turns out that a large portion of the cells in healthy people carry far more mutations than expected, including some mutations thought to be the prime drivers of cancer. These mutations make a cell grow faster than others, raising the question of why full-blown cancer isn’t far more common.

“This is quite a fundamental piece of biology that we were unaware of,” said Inigo Martincorena, a geneticist at the Wellcome Sanger Institute in Cambridge, England.

. . .

Dr. Martincorena and his colleagues reported their findings on Thursday [Oct. 18, 2018] in the journal Science.

By examining the mutations, the researchers were able to rule out external causes for them, like tobacco smoke or alcohol. Instead, the mutations seem to have arisen through ordinary aging. As the cells divided over and over again, their DNA sometimes was damaged. In other words, the rise of these mutations may just be an intrinsic part of getting older.

. . .

The study . . . raised questions about efforts to detect cancer at its earliest stages, when cancer cells are still rare, Dr. Kennedy said: “Just because someone has mutations associated with cancer doesn’t mean actually they have a malignancy.”

Given the abundance of cancer mutations in healthy people, why isn’t cancer more common? Dr. Martincorena speculated that a healthy body may be like an ecosystem: Perhaps clones with different mutations arise in it, compete for available space and resources, and keep each other in check.

If so, fighting cancer might one day be a matter of helping harmless clones outcompete the ones that can lead to deadly tumors.

Medical Researchers Have Incentive to Exclude Older Patients from Clinical Trials

As human beings, medical researchers would like to offer experimental therapies to whoever needs them and is willing to take the risks and uncertainty of new frontiers. But as practical medical researchers medical researchers know their careers depend on the success of their clinical trials, and the success of their clinical trials depends on the number of patients who thrive on the new therapy. So their personal incentive is to cherry-pick clinical trial enrollees, picking only the most robust who are most likely to thrive. The solution? Allow medical researchers to be both human beings and medical researchers. Allow them to give the therapy to those at high risk, based on their cumulative experience and judgement. Not all sound actionable knowledge arises from randomized double-blind clinical trials.

(p. A5) Many cancer trials cap enrollment at age 65. Even when trials for older people are available, oncologists are reluctant to enroll elderly patients because frailties might make them less resilient against side effects from toxic treatments, according to a 2020 study in an American Cancer Society journal. People over 70 represent a growing share of the cancer-patient population but are vastly underrepresented in clinical trials, the study said.

“How can we make decisions for people over 70 if people over 70 are not included in the trials that we use to base our decision making?” said Dr. Mina Sedrak, deputy director of the Center for Cancer and Aging at City of Hope, a cancer center near Los Angeles and an author of the paper.

. . .

The Food and Drug Administration guidelines recommend “adequate representation” of the elderly in cancer trials, including people over age 75. The Journal of the National Cancer Institute in December 2022 published a series of papers presented at a workshop focused on how to improve trial enrollment of older people.

Researchers have developed geriatric assessment tools that try to predict patients’ survival chances based on more than age alone. Professional groups are also working to try to address gaps. Despite these efforts, enrollment of older patients still lags behind, cancer doctors said.

. . .

To participate in many trials involving transplants, patients would have to undergo the more intense chemotherapy whether randomly assigned to receive an experimental treatment or the standard of care. That makes it harder to incorporate older patients into randomized trials, cancer doctors said.

When a Therapy Fails in a Clinical Trial, Is That the Fault of the Therapy or of the Trial?

When a proposed therapy fails in a clinical trial is that because the therapy can’t work, or is it because the trial itself was flawed? It is far from written in stone how a clinical trial should be set up. Should the therapy be given by pill or intravenously? In what doses? How often, for how long? At what stage of the disease? Because Stage 3 clinical trials are so expensive and difficult to implement, some therapies may have only one shot to succeed. How many therapies that could have helped some people, will never do so, because the researchers had bad luck, or less skill, in implementing the trial? This problem could be reduced the regulatory mandate to requiring only the Stage 1 and Stage 2 clinical trials, that mainly establish safety (as opposed to the much-more-expensive Stage 3 that mainly establishes efficacy). That way researchers who lacked the deep pockets of the researchers discussed in the article quoted below, could still more often afford multiple shots at designing a trial that would succeed at identifying what therapy, applied to which patients, in what modalities, might cure them, or at least lengthen their lives, or reduce their symptoms. Some of the greatest advances in medicine occurred in an environment of quick trial and error, as when medicine has to be precticed on the battlefield of war, or when Emil Freireich improvised new ingredients for his chemo cocktail to cure some children of childhood leukemia or when Freireich’s protégé Vincent DaVita did the same to cure some adults of Hodgkin’s lymphoma. Ideally I would eliminate all mandates, both to enhance liberty, and to speed trial-and-error therapies. But here I suggest eliminating only Stage 3 clinical trials, not because I think that is ideal, but (following Milton Freidman) because I suspect that policy reform may be the best that is politically feasible. We would maximize trial and error adjustments by eliminating all mandated clinical trials. In the vast majority of decisions in life we make judgements without the benefit of a clinical trial. And such judgements usually are effective and improve with experience. [Gary Klein persuasively makes this point through a multitude of examples, in his tour de force Sources of Power.] What is done in life generally, can also be done in medicine in particular, bringing us more cures, faster.

(p. D4) “There is no reason why cancer vaccines would not work if given at the earliest stage,” said Sachet A. Shukla, who directs a cancer vaccine program at MD Anderson Cancer Center. “Cancer vaccines,” he added, “are an idea whose time has come.” (Dr. Shukla owns stock in companies developing cancer vaccines.)

That view is a far cry from where the field was a decade ago, when researchers had all but given up. Studies that would have seemed like a pipe dream are now underway.

“People would have said this is insane,” said Dr. Susan Domchek, the principal investigator of a breast cancer vaccine study at the University of Pennsylvania.

. . .

“We had this trial, 63 patients, Stage 4 cancer. They had failed all therapies,” Dr. Finn said.

. . .

In their initial studies, it became clear to Dr. Finn and her colleagues that the cancers were too far advanced for immunizations to work. After all, she notes, with the exception of rabies, no one vaccinates against an infectious disease in people who are already infected.

“I said, ‘I don’t want to do that again,’” Dr. Finn said. “It is not the vaccines. We have to look at different patients.”

Now, she and her colleague at Pittsburgh, Dr. Robert Schoen, a gastroenterologist, are trying to prevent precancerous colon polyps with a vaccine. But intercepting cancer can be tricky.

They focused on people whose colonoscopies had detected advanced polyps — lumps that can grow in the colon, but only a minority of which turn into cancer. The goal, Dr. Schoen said, was for the vaccine to stimulate the immune system to prevent new polyps.

It worked in mice.

“I said, ‘OK, this is great,’” Dr. Schoen recalled.

But a recently completed study of 102 people at six medical centers randomly assigned to receive the preventive vaccine or a placebo had a different result. All had advanced colon polyps, giving them three times the risk of developing cancer in the next 15 years compared to people with no polyps.

Only a quarter of those who got the vaccine developed an immune response, and there was no significant reduction in the rate of polyp recurrences in the vaccinated group.

“We need to work on getting a better vaccine,” Dr. Schoen said.

. . .

Dr. Domchek said she can envision a future in which people will have blood tests to find cancer cells so early that they do not show up in scans or standard tests.

“To paint a grand future,” she said, “if we knew the tests predicted cancer we could say, ‘Here’s your vaccine.’”

New Evidence American Indians Were Eating a Lot of Mammoth Meat During the Time When Mammoths Became Extinct

Scientists once thought that the extinction of megafauna like mammoths was due mainly to climate change. But the extinction in America coincided with the arrival of humans, leading some to argue that early indigenous American Indians killed off the mammoths. This goes against the politically correct stereotype that American Indians were mostly peace-loving environmentalists.

A recently published article provides additional evidence. Using a skull from the Clovis period, roughly during the period when mammoths became extinct, the authors were able to conclude from the young child’s “isotopic signature” that two-thirds of the child’s diet came from his mother’s breast-milk, and one third mainly from the meat of large mammals like mammoths. They could also infer that the mother had a diet high in mammoth meat. Summarizing the academic article in The New York Times, columnist Carl Zimmer says: “a study analyzing the ancient bones of a young child who lived in Montana suggests that early Americans hunted mammoths and other giant mammals to oblivion” (p. D3).

I am not criticizing the early American Indians. If I had been alive back then and I could obtain nutrition for me and my family by slaughtering a few mammoths, I would have tried to do so. But we are making a mistake if we reject American exceptionalism in part on the basis of a false and sanctimonious claim that the indigenous American Indians acted on morally superior environmental values.

My musings above are based partly on the commentary:

Will Cancer Die from a Magic Rifle Bullet or From Magic Shotgun Pellets?

We dream of a magic bullet that can cure all cancer. But will all “cancer” continue to be seen as one unified disease, with potentially one common cure? Or will we see many diseases, many causes, and many cures? [The idea of a “magic bullet” against a disease was born from the great Paul Ehrlich who found one of the first effective antibiotics (not to be confused with the the more recent environmentalist Paul Ehrlich who is famous for losing his bet with the great Julian Simon).]

(p. D3) A new study, published [online on] Wednesday [Oct. 2, 2019] in the journal Nature, found that fungi can make their way deep into the pancreas, which sits behind your stomach and secretes digestive enzymes into your small intestine.

. . .

One particular fungus was the most abundant in the pancreas: a genus of Basidiomycota called Malassezia, which is typically found on the skin and scalp of animals and humans, and can cause skin irritation and dandruff. . . .

The results show that Malassezia was not only abundant in mice that got pancreatic tumors, it was also present in extremely high numbers in samples from pancreatic cancer patients, said Dr. Berk Aykut, a postdoctoral researcher in Dr. Miller’s lab.

. . .

Administering an antifungal drug got rid of the fungi in mice and kept tumors from developing. And when the treated mice again received the yeast, their tumors started growing once more — an indication, Dr. Aykut said, that the fungal cells were driving the tumors’ growth.

. . .

The new study also sheds light on how fungi in the pancreas may drive the growth of tumors. The fungi activate an immune system protein called mannose-binding lectin, which then triggers a cascade of signals known to cause inflammation. When the researchers compromised the ability of the lectin protein to do its job, the cancer stopped progressing and the mice survived for longer.

Medical Mergers Can Reduce Competition and Raise Prices When Government Aids Incumbents or Fetters Entrepreneurs

The story quoted below gives useful evidence that in the recent past hospital mergers have generally resulted in higher prices. But the story is incomplete, creating the misleading impression that government antitrust action is clearly needed. My hypothesis: mergers can increase efficiency and lower patient prices, but only tend to do so when hospitals are constrained by the real or potential entry of entrepreneurial health providers. Unfortunately entry is currently very limited, often by government actions. Often new hospitals must acquire a certificate of need before they are allowed to exist.

Often, incumbent hospitals successfully object to those certificates. Federal subsidies differentially go to large incumbent hospitals. Federal Covid-relief funds went to large incumbent hospitals that used much of the funds to buy up other hospitals. Less directly, enormous government regulation creates a differential burden on the small new entrant that likely cannot afford the huge specialized staff to successfully navigate the voluminous opaque regulations.

If we want lower prices, government should allow mergers, but also stop creating constraints that discourage entry. Government should especially reduce the regulations that discourage medical entrepreneurship.

(p. D4) The nation’s hospitals have been merging at a rapid pace for a decade, forming powerful organizations that influence nearly every health care decision consumers make.

The hospitals have argued that consolidation benefits consumers with cheaper prices from coordinated services and other savings.

But an analysis conducted for The New York Times shows the opposite to be true in many cases. The mergers have essentially banished competition and raised prices for hospital admissions in most cases, according to an examination of 25 metropolitan areas with the highest rate of consolidation from 2010 through 2013, a peak period for mergers.

The analysis showed that the price of an average hospital stay soared, with prices in most areas going up between 11 percent and 54 percent in the years afterward, according to researchers from the Nicholas C. Petris Center at the University of California, Berkeley.

The new research confirms growing skepticism among consumer health groups and lawmakers about the enormous clout of the hospital groups. While most political attention has focused on increased drug prices and the Affordable Care Act, state and federal officials are beginning to look more closely at how hospital mergers are affecting spiraling health care costs.

During the Obama years, the mergers received nearly universal approval from antitrust agencies, with the Federal Trade Commission moving to block only a small fraction of deals. State officials generally looked the other way.

President Trump issued an executive order last year calling for more competition, saying his administration would focus on “limiting excessive consolidation (p. B1) throughout the health care system.” In September [2018], Congress asked the Medicare advisory board to study the trend.

. . .

Prices rise even more steeply when these large hospital systems buy doctors’ groups, according to Richard Scheffler, director of the Petris Center.

“It’s much more powerful when they already have a very large market share,” said Mr. Scheffler, who recently published a study on the issue in Health Affairs. “The impact is just enormous.”

Some Medical Researchers Seek Patient Input on Execution of Studies

In the story quoted below some medical researchers are seeking patient involvement in studies, but I was disappointed to realize that the involvement is mostly superficial with the aim of getting patient agreement to be part of the study. The researchers in the story still see a big divide between patients and doctors. Doctors see patterns and create hypotheses to be tested. Patients, if they want, can stand by posters, and make minor suggestions on the execution of study design.

I suggest, more ambitiously, that patients sometimes, if allowed, can see patterns and create hypotheses. They have the incentive, the skin in the game. And sometimes they have direct experience on what works and what does not work.

(p. R6) Joel Nowak, a 66-year-old Brooklyn, N.Y., resident with metastatic prostate cancer, knows a lot about cancer research. Over the years, he has contributed blood, saliva and medical information to studies in hopes of helping investigators battle the disease.

But something has nagged at him. Almost always, Mr. Nowak says, investigators want data, “but you never hear from them again.”

Then he was asked to join a new endeavor that is trying to change that—by making participants into partners.

The Metastatic Prostate Cancer Project, launched by the Broad Institute of MIT and Harvard and the Dana-Farber Cancer Institute in Boston, is trying to give participants a bigger stake in studies by asking them for input, inviting them to events and keeping them updated on progress.

. . .

Patients are . . . invited for a tour of the Broad Institute to see its gene-sequencing machines or to meet and share ideas with researchers, says Nikhil Wagle, director of the umbrella initiative.

Dr. Wagle thinks the approach has led to unusually fast and large enrollment. More than 4,000 people enrolled in the breast-cancer project and over 290 in the angiosarcoma initiative. In just a few weeks, more than 200 signed up for the prostate-cancer study.

. . .

Keeping participants up-to-date is another concern for researchers. It is an issue close to home for Corrie Painter, principal investigator of the angiosarcoma project at the Broad and one of the creators of all three of the institute’s cancer initiatives.

Dr. Painter draws on her experiences as a cancer survivor and research participant in shaping interactions with patients. She was diagnosed with angiosarcoma nearly eight years ago. Dr. Painter says that after her diagnosis, like many patients, she felt frustrated at being treated more “as passive recipients of care rather than part of the process of discovery.”

. . .

Meanwhile, some patients are taking the opportunity to play a larger role in shaping studies. Mr. Nowak, for one, joined a patient advisory council of the prostate-cancer project. Members communicate on videoconferences, email exchanges and in person. During a meeting at the Broad, researchers showed a prototype for the saliva kits that were going to be mailed to patients to collect samples.

The advocates told researchers to take “Metastatic Prostate Cancer Project” off the box. “There are a lot of men who don’t want other people to know they have cancer,” says Mr. Nowak.

Large Medical Databases Would Allow Discovery and Testing of Causal Patterns of Diseases

After considerable effort, as of the writing of the article quoted below, Dr. Wagle has only been able to gather data on 375 of the roughly 155,000 metastatic breast cancer patients in the U.S. Many have long complained about the difficulty in obtaining and consolidating medical records. Exploring the reasons would take a longer article than the one quoted below. Part of the story is the Health Insurance Portability and Accountability Act of 1996 (HIPAA). It was passed to protect patient privacy, but it served as cover for medical institutions to stonewall patients, policy makers, and other medical institutions from obtaining information. The institutions make the process of obtaining medical information as slow, opaque, and onerous as possible. Partly this is a result of the general inefficiency of medical bureaucracy. Regulations limit competition among medical institutions and limit entrepreneurship, allowing inefficiencies to persist. To those who are mission-oriented within the bureaucracy, providing records may seem a lower priority than issues affecting current medical care. But also, restricting information may increase patient lock-in. Ceteris paribus, a patient may choose to stay at an institution that has long health records for the patient. Also, providing less information to third parties may make the institution less vulnerable to criticism and law suits.

Ideally, Dr. Wagle’s database would serve as a modern day version of the dusty hospital archives that Dr. William Coley pursued to find a pattern among the patients who had been spontaneously cured of their cancer in the late 1800s.

From personal experience I can say that getting patient information is easier now than it was 30 years ago, at least for the patient to obtain their own information.

An important side point is Dr. Wagle’s emphasis on the value of obtaining patient narratives, in addition to coded data. Narratives allow the discovery of additional causes or effects, beyond what the initial coders include in the coded data. Gary Klein makes this point in defending the value of what he calls “stories” (Klein 2017).

(p. D4) Dr. Nikhil Wagle thought he had a brilliant idea to advance research and patient care.

Dr. Wagle, an oncologist at the Dana Farber Cancer Institute in Boston, and his colleagues would build a huge database that linked cancer patients’ medical records, treatments and outcomes with their genetic backgrounds and the genetics of their tumors.

The database would also include patients’ own experiences. How ill did they feel with the treatments? What was their quality of life? The database would find patterns that would tell doctors what treatment was best for each patient and what patients might expect.

The holdup, he thought, would be finding patients. Instead, the real impediment turned out to be gathering their medical records.

. . .

Dr. Wagle is making data from medical records and patients’ experiences public as he gets them. After 2 1/2 years, though, he is disappointed by how little there is to share.

The patient who inspired his project had a lethal form of thyroid cancer. She was expected to die in a few months. In desperation, doctors gave her a drug that by all accounts should not have helped.

To everyone’s surprise, her tumors shrank to almost nothing, and she survived. She was an “extraordinary responder.”

Why? It turned out that her tumor had an unusual mutation that made it vulnerable to the drug.

And that got Dr. Wagle thinking. What if researchers had a database that would allow them to find these lucky patients, examine their tumors, and discover genetic mutations that predict which drugs will work?

. . .

Dr. Wagle decided to build a database, starting with metastatic breast cancer, his specialty. There are about 155,000 metastatic breast cancer patients in the United States. He would use social media, online forums and advocacy groups to reach out to patients for their records.

. . .

Startlingly, faxing “is the standard,” Ms. McGillicuddy said, for medical records requests.

The process can be frustrating. Fax numbers can be out of date. Some medical centers will not accept electronic patient signatures on the permission forms.

Sometimes, the medical centers just ignore the request — and the second request. In the end, Ms. McGillicuddy said, the project gets fewer than half the records it requests.

Then comes the laborious task of extracting medical information from the records and entering it into the database. A faxed medical record may be 100 or 200 pages long.

So far, the breast cancer project has received 450 records for 375 patients. (Each patient tends to have more than one record, because the women typically are seen at more than one medical center.)

When Free People Do Not Volunteer for Clinical Trials, Should Researchers Recruit Prisoners?

On the issue of how to ethically motivate prisoners to volunteer for clinical trails on the efficacy of salt-restricted diets, why not offer wages to the prisoners? Prisoners are already sometimes paid small amounts for other activities, like making license plates. Better yet, take my suggestion with a grain of salt, and settle the dispute with well-done observational studies.

(p. D3) Suppose you wanted to do a study of diet and nutrition, with thousands of participants randomly assigned to follow one meal plan or another for years as their health was monitored?

In the real world, studies like these are nearly impossible. That’s why there remain so many unanswered questions about what’s best for people to eat. And one of the biggest of those mysteries concerns salt and its relationship to health.

But now a group of eminent researchers, including the former head of the Food and Drug Administration, has suggested a way to resolve science’s so-called salt wars. They want to conduct an immense trial of salt intake with incarcerated inmates, whose diets could be tightly controlled.

The researchers, who recently proposed the idea in the journal Hypertension, say they are not only completely serious — they are optimistic it will happen.

. . .

Dr. Daniel W. Jones, a professor of medicine and physiology at the University of Mississippi School of Medicine and former president of the American Heart Association, was alarmed by the bitter arguments and increasingly personal disputes between researchers who disagree about salt.

So he invited senior medical scientists on both sides of the debate to meet in Jackson, Miss., to figure out how to settle their differences.

. . .

So suppose you do the study in prisons, said Dr. Jones. Is the research supposed to benefit the prisoners or just the population in general? If the prisoners would not benefit, the study would be unethical.

People who are not incarcerated can choose how much sodium they consume, but prisoners cannot — they eat whatever the facility provides. If there is uncertainty about the ideal amount of sodium, the experts concluded, prisoners would benefit from a study that settled the matter.

. . .

Dr. Macklin, in a telephone interview, also said many prisoners would be happy to jump in. She has taught in a maximum security facility and has studied the ethics of doing research in prisons.

“They would say they want to give back to society,” Dr. Macklin said.

. . .

Prison administrators have told Dr. Jones they would be willing to consider a proposal for a randomized trial of salt.

If Immortality Does Not Violate the Laws of Physics, Entrepreneurs Can Achieve It

The late Nobel-Prize-winning physicist and idiosyncratic Richard Feynman also said something similar to the quote attributed to Arram Sabeti below.

I do not believe that Feynman was explicitly named, or had any lines, in the movie “Opennheimer,” but you can see his character in the background of one scene playing the bongo drums. Perhaps he was eccentric, but I liked his views on methodology and his unpretentious, optimistic, and straightforward spirit.

(p. 9) As the longevity entrepreneur Arram Sabeti told The New Yorker: “The proposition that we can live forever is obvious. It doesn’t violate the laws of physics, so we can achieve it.”

The Academic “Herd Mindset” May Be the Cause of What Elon Musk Calls the “Woke Mind Virus”

(p. B3) “I listen to podcasts about the fall of civilizations to go to sleep,” Musk said this past week during an appearance at the Milken Institute conference. “So perhaps that might be part of the problem.”

One provocateur, in particular, has caught his attention of late: Gad Saad, a marketing professor at Concordia University in Montreal, and author of the book “The Parasitic Mind: How Infectious Ideas Are Killing Common Sense.”

. . .

Saad wrote that “The Parasitic Mind” was inspired, in part, by his experience in academia, where he described a herd mindset that chastised innovative thinkers. He described pushback he encountered, including his ideas being labeled as “sexist nonsense” and his efforts to use “biologically-based theorizing” to explain consumer behavior being dismissed as too reductionistic.

“The West is currently suffering from such a devastating pandemic, a collective malady that destroys people’s capacity to think rationally,” the 59-year-old Saad wrote at the beginning of his book. “Unlike other pandemics where biological pathogens are to blame, the current culprit is composed of a collection of bad ideas, spawned on university campuses, that chip away at our edifices of reason, freedom, and individual dignity.”

. . .

Another inspiration for his book, Saad writes, was his experience as a boy fleeing with other Jews from his home in Lebanon during that country’s civil war. In the book, he detailed some of the horrors he experienced, including the kidnapping of his parents.

. . .

Musk has said his concerns about Woke Mind Virus, his way of labeling progressive liberal beliefs that he says are overly politically correct and stifling to public debate and free speech, helped fuel his desire to acquire the social-media company Twitter turned X in late 2022.
