More Breast Cancer Awareness Month pseudoscience from (who else?) Joe Mercola

I have mixed emotions regarding Breast Cancer Awareness Month. On the one hand, I look forward to it because it provides us with a pretext to get out science-based messages about breast cancer and to highlight a lot of the cool science that we do at our cancer center. On the other hand, the quacks see an opportunity in Breast Cancer Awareness Month to spread their message too. That message, not surprisingly, generally involves attacking science-based modalities for the detection and treatment of breast cancer and promoting their “alternative” methods. For example, last year, Christiane Northrup promoted thermography as somehow being better than mammography for the early detection of breast cancer. It’s not. Yet there she is this year again, still promoting the same nonsense. In years past, I’ve seen people like Dennis Byrne promoting a link between abortion and breast cancer, a link that is not supported by science. I’ve seen the likes of Mike Adams claiming that Breast Cancer Awareness Month is nothing more than a conspiracy by the male-dominated “cancer industry” to keep women down and misinformation about “myths” of breast cancer while likening the “cancer industry” to Nazi extermination camp commanders and chemotherapy to Zyklon-B. I kid you not about that last part. Indeed, during October, I frequently get to look forward to images like this one (click for a larger image):

Steve Jobs’ medical reality distortion field

As I pointed out in my previous post about Steve Jobs, I’m a bit of an Apple fan boy. A housemate of mine got the very first Mac way back in 1984, and ever since I bought my first computer that was mine and mine alone back in 1991 (a Mac LC), I’ve used nothing but Macintosh computers, except when compelled to use Windows machines by work—and even then under protest. Indeed, as I searched for jobs at various times in my life, I asked myself whether I could accept a job at an institution that didn’t permit me to have a Mac in my office, such as the V.A. Fortunately, I never had to make that choice. All of this explains why I paid a lot of attention to Steve Jobs and also why his death saddened me and, relevant to this blog, the clinical history of the cancer that killed him fascinates me.

It’s often been said that there was a sort of “reality distortion field” around Steve Jobs. It was a part joking, part derogatory, part admiring term applied to Jobs’ talent for persuasion in which, through a combination of personal charisma, bravado, hyperbole, marketing, and persistence, Jobs was able to persuade almost anyone, even developers and engineers, of almost anything. In particular, it referred to his ability to convince so many people that each new Apple product was the greatest thing ever, even when that product had obvious flaws. Unfortunately, as more news comes out about how Steve Jobs initially dealt with his diagnosis of a neuroendocrine tumor of the pancreas (specifically, an insulinoma) back in 2003 and 2004, it’s become apparent that Jobs had his own medical reality distortion field, at least in the beginning right after his diagnosis of a rare form of pancreatic cancer, that allowed him to come to think that he might be able to reverse his cancer with diet plus various “alternative” modalities.

In the immediate aftermath of Steve Jobs’ death, I summarized the facts about Jobs’ case that were known at the time. In particular, I took issue with the claims of a skeptic that “alternative medicine killed Steve Jobs.” At the time, I pointed out that, although it was very clear that Steve Jobs did himself no favors by delaying his initial surgery for nine months after his initial diagnosis, we do not have sufficient information to know what his clinical situation was and therefore how much, if at all, he decreased his odds of survival by not undergoing surgery expeditiously. To recap: Did Steve Jobs harm himself by trying diet and alternative medicine first? Quite possibly. Did alternative medicine kill him? As I’ve argued before, that’s impossible to say, and any skeptic who dogmatically makes such an argument has taken what we known beyond what can be supported. Regular readers know that when I see a story that looks as though “alternative medicine” directly contributed to the death of someone, I usually pull no punches, but in this case I had a hard time being so definitive because the unknowns are too many, with all due respect to Ramzi Amri, a Research Associate at Harvard Medical School who in my opinion also went too far. I did, however, point out that I’m always open to changing my opinion if new evidence comes in. Jobs was always incredibly secretive about his medical condition, so much so that it didn’t even come out in the press until after it had happened that he had undergone a liver transplant in 2008 for metastatic insulinoma in his liver, just as his cancer diagnosis in 2003 remained secret for 9 months, not being revealed until he sent an e-mail to Apple employees announcing that he had undergone surgery.

It turns out that, with the imminent release of a major biography of Steve Jobs, more information is finally trickling out about his medical history. For instance, Jobs’ biographer Walter Isaacson is going to appear on 60 Minutes this Sunday, and apparently he is going to say this:

Steve Jobs’ cancer and pushing the limits of science-based medicine

Editor’s note: There is an update to this post.

An Apple fanboy contemplates computers and mortality

I’m a bit of an Apple fanboy and admit it freely. My history with Apple products goes way back to the early 1980s, when one of my housemates at college had an Apple IIe, which I would sometimes use for writing, gaming, and various other applications. Indeed, I remember one of the first “bloody” battle games for the IIe. It was called The Bilestoad and involved either taking on the computer or another opponent with battle axes in combat that basically involved hacking each other’s limbs off, complete with chunky, low-resolution blood and gore. (You youngsters out there will be highly amused at the gameplay here.) Of course, it’s amazing that nothing’s changed when it comes to computer games except the quality of graphics. Be that as it may, this same roommate was one of the first students to get a hold of the new Macintosh when it was released in early 1984. I really liked it right from the start but only got to play with it occasionally for a few months. After using a Macintosh SE to do a research project during my last year of medical school, I have used the Macintosh platform more or less exclusively, and the first computer I purchased with my own money was a Mac LC back in 1990 or 1991. Today, I have multiple Apple products, including my MacBook Air, my iPhone, and my old school iPod Classic, among others. Oddly enough, I do not have an iPad, but that’s probably only a matter of time, awaiting software that lets me do actual work on it.

All of this is my typical long-winded way of explaining why I was immensely saddened when I learned of Steve Jobs’ death last week. Ever since speculation started to swirl about his health back 2004 and then again in 2008, capped off by the revelation that he had undergone a liver transplant for a rare form of pancreatic cancer in 2009, I feared the worst. Last week, the end finally came. However, there is much to learn relevant to the themes of this blog in examining the strange and unusual case of Steve Jobs. Now, after his death five days ago, which coincidentally came a mere day after the launch of iCloud and the iPhone 4S, it occurs to me that it would be worthwhile to try to synthesize what we know about Jobs’ battle with cancer and then to discuss the use (and misuse) of his story. Of course, this is a difficult thing to do because Jobs was notoriously secretive and I can only rely on what has been published in the media, some of which is conflicting and all of which lacks sufficient detail to come to any definite conclusions, but I will try, hoping that the upcoming release of his biography by Walter Isaacson in couple of weeks might answer some of the questions I still have remaining, given that Isaacson followed Jobs through his battle with cancer and was given unprecedented access to Jobs and those close to him.

In the meantime, I speculate. I hope my speculations are sufficiently educated as not to be shown to be completely wrong, but they are speculations nonetheless.

The wrong way to “open up” clinical trials

Science-based medicine rests on twin pillars that are utterly essential to the development of treatments that are safe and efficacious. Both of these pillars depend on science, but in different ways. The first of these is, of course, the basic science that provides the hypotheses to test about the mechanisms behind the diseases and malfunctions that plague the human body. This basic science suggests ways of either correcting or alleviating these malfunctions in order to alleviate symptoms and prevent morbidity and mortality and how to improve health to increase quality and quantity of life. Another critical aspect of basic science is that it also provides scientists with an estimate of the plausibility of various proposed interventions, treatments and cures designed to treat disease and improve health. For example, if a proposed remedy relies upon ideas that do not jibe with some of the most well-established laws in science, such as homeopathy, the concepts behind which violate multiple laws of physics and chemistry, it’s a very safe bet that that particular treatment will not work and that we should test something else. Of course, the raison d’être of this blog derives from the unfortunate fact that in today’s medicine this is not the case and we are wasting incredible amounts of time, money, and lost opportunities in order to pursue the scientific equivalent of fairy dust as though it represented a promising breakthrough that will save medicine, even though much of it is based on prescientific thinking and mysticism. Examples include homeopathy, reiki, therapeutic touch, acupuncture, and much of traditional Chinese medicine and Ayurveda, all of which have managed to attach themselves to medical academia like kudzu.

Of course, basic science alone is not enough. Humans are incredibly complex organisms, and what we consider to be an adequate understanding of disease won’t always result in an efficacious treatment, no matter how good the science is. Note that this is not the same thing as saying that utter implausibility from a scientific basis (as is the case with homeopathy) doesn’t mean a treatment won’t work. When a proposed treatment relies on claiming “memory” for water that doesn’t exist or postulates the existence of a “life energy” that no scientific instrument can detect and the ability to manipulate that life energy that no scientist can prove, it’s a pretty safe bet that that treatment is a pair of fetid dingo’s kidneys. Outside of these sorts of cases, though, clinical trials and epidemiological studies are the second pillar of science-based medicine, in particular clinical trials, which is where the “rubber hits the road,” so to speak. In clinical trials, we take observations from the laboratory that have led to treatments and test them in humans. The idea is to test for both safety and efficacy and then to begin to figure out which patients are most likely to benefit from the new treatment.

Andrew Weil and “integrative medicine”: The ultimate triumph of quackery?

A board certification in woo?

I’ve been harshly critical of the entire concept of “integrative medicine” (IM), which has over the last few years nearly supplanted the former term used for non-science-based medicine or medicine based on prescientific ideas represented as though it were scientific medicine, “complementary and alternative medicine” (CAM). Indeed, just last week I pointed out how IM is far more about marketing than it is about science or medicine, and over the last three years I’ve been particularly harsh on the concept of “integrative oncology,” which is actually being represented as a “subspecialty” of IM. Despite the utter lack of a rationale based on science or the scientific basis of medicine, IM has still been making inroads into academic medical centers, where I tend to refer to it with the unapologetically disparaging term “quackademic medicine.” Even worse, now, increasingly, such woo has been insinuating its way into community medical centers as well.

Arguably, the man who has done more than any individual to promote the quackification of science-based medicine is Dr. Andrew Weil. (At least, I can’t think of any single person who’s done more during his lifetime to promote the infiltration of quackery into medicine. Readers are free to chime in if they know of someone who could challenge Weil for the title of King of Quackademic Medicine.) As I pointed out the last time I discussed him, Dr. Weil doesn’t really like science-based medicine. Oh, no, he doesn’t like it at all. Unfortunately, he’s been very successful in promoting quackademic medicine. He’s also arguably been the single most successful person at legitimizing what used to be viewed as quackery. Master of the domain of “integrative medicine,” having formed a model of an “integrative medicine in residency” that’s spread like kudzu through quackademia, all from his redoubt at the University of Arizona, Dr. Weil has now announced his intention for the next phase of his “integrating” pseudoscience with SBM. I learn this from The Integrator Blog, which has as a recent headline from last week Special Report: “Strategic Change in Direction” as Weil’s Arizona Center Commits to Creation of American Board of Integrative Medicine:

In a major strategic shift, the University of Arizona Center for Integrative Medicine (ACIM) has announced that it will lead the creation of a formal specialty for medical doctors in integrative medicine. ACIM, founded by Andrew Weil, MD and directed by Victoria Maizes, MD, is in dialogue with the American Board of Physician Specialties toward establishing an American Board of Integrative Medicine. They are collaborating with leaders of the American Board of Integrative and Holistic Medicine (ABIHM). Here is the ACIM announcement, a statement from two ABIHM leaders, a brief interview with Maizes and the list of 18 founding Board members. Is this the right strategic choice? What impact will this have on integrative medicine and the broader integrative healthcare movement?

Survey says, “Hop on the bandwagon of ‘integrative medicine’!”

A Brief Clinical Vignette

In researching this post, I found an article published nearly two years ago in The Hospitalist entitled Growth Spurt: Complementary and alternative medicine use doubles, which began with this anecdote:

Despite intravenous medication, a young boy in status epilepticus had the pediatric ICU team at the University of Wisconsin School of Medicine and Public Health in Madison stumped. The team called for a consult with the Integrative Medicine Program, which works with licensed acupuncturists and has been affiliated with the department of family medicine since 2001. Acupuncture’s efficacy in this setting has not been validated, but it has been shown to ease chemotherapy-induced nausea and vomiting, as well as radiation-induced xerostomia.

Following several treatments by a licensed acupuncturist and continued conventional care, the boy’s seizures subsided and he was transitioned to the medical floor. Did the acupuncture contribute to bringing the seizures under control? “I can’t say that it was the acupuncture — it was probably a function of all the therapies working together,” says David P. Rakel, MD, assistant professor and director of UW’s Integrative Medicine Program.

The UW case illustrates both current trends and the constant conundrum that surrounds hospital-based complementary medicine: Complementary and alternative medicine’s use is increasing in some U.S. hospitals, yet the existing research evidence for the efficacy of its multiple modalities is decidedly mixed.

My jaw dropped in horror when I read this story. Acupuncture for status epilepticus? There’s no evidence that it works and no scientific plausibility suggesting that it might work. And what does the questionable research suggesting that acupuncture might ease chemotherapy-induced nausea and vomiting or radiation-induced xerostomia (which, if you look more closely at the studies, it almost certainly does not, but that’s a post for another time) have to do with this case, anyway? Nothing. Worse, Dr. Rakel fell for the classic post hoc ergo propter hoc fallacy; i.e., despite his disclaimer, he appears to be implying that, because the child recovered, acupuncture must have contributed to his recovery. He also repeats the classic fallacy that I’ve written about time and time again in the context of cancer therapy, namely that if a patient is using quackery as well as science-based medicine, then either it was the quackery that cured him or the quackery somehow made the conventional medical care work better.

I expect better from an academic medical center like the University of Wisconsin. Unfortunately, increasingly I’m not getting it. Quackademic medicine is infiltrating such medical centers like kudzu.

Chemotherapy doesn’t work? Not so fast…




I’ve lost count of how many times I’ve come across statements like the ones above, often in all caps, quite frequently with more than one exclamation point, on the websites of “natural healers,” purveyors of “alternative medicine.” In fact, if you Google “chemotherapy doesn’t work,” “chemotherapy is poison,” or “chemotherapy kills,” you’ll get thousands upon thousands of hits. In the case of “chemotherapy kills,” Google will even start autofilling it to read “chemotherapy kills more than it saves.” The vast majority of the hits from these searches usually come from websites hostile to science-based medicine. Examples include, the website of “alternative medicine entrepreneur” Dr. Joe Mercola and, the website of Mike Adams, where you will find cartoons like this one, which likens the administration of chemotherapy to a Nazi death camp:

Quoth the anti-vaccine group SANE Vax: Beware HPV DNA in Gardasil!

Every so often, there’s a bit of misinformation that starts spreading around the Internet that shows up in enough places that our readers take notice and e-mail us about it. What happens is that these in essence become “requests.” We at SBM are, of course, happy to consider all requests and sometimes will actually take them on, particularly when doing so will be educational about the mission of this blog, namely discussing science-based medicine and providing much needed critical analysis to the pseudoscience that is, alas, becoming more and more common in medicine. A frequent topic of this blog is, not surprisingly, the anti-vaccine movement, which is arguably the most dangerous (to public health, at least) pseudoscience movement currently in existence. The misinformation about vaccines that anti-vaccine activists spread through websites, podcasts, radio, TV, and other media is protean, and it’s difficult to keep up with it all.

Which is probably why I hadn’t heard this bit of misinformation about the HPV vaccine from an anti-vaccine group I hadn’t heard of before (or at least didn’t remember) called SANE Vax. (I include the “Inc.” because SAFE Vax, Inc. itself insists on using it frequently in all its press releases.) If you’ve been in the biz a while, as I have, you can tell right away from the very name of this website exactly where its creators are coming from. Here’s a hint. It’s not the mission that the website claims that it is, which is stated thusly:

Seven Deadly Medical Hypotheses revisited

Back in February, Mark Crislip and I both deconstructed an article written by Dr. Reynold Spector that appeared in the March/April issue of Skeptical Inquirer (SI), the flagship publication for the Committee for Skeptical Inquiry (CSI). The article was entitled Seven Deadly Medical Hypotheses, and, contrary to the usual standard of articles published in SI, it used a panoply of spin, bad arguments, and, yes, misinformation to paint a picture of seven horrifically deadly “medical hypotheses,” most of which, even if the reader accepted Dr. Spector’s arguments at face value in a worst case scenario, weren’t actually all that deadly at all, with the alleged deadliness of the others being in dispute. In addition, Dr. Spector painted a picture of medical science that is not nearly rigorous enough. While we at SBM would probably agree that much of medical science is insufficiently rigorous, given how so-called “complementary and alternative medicine” (CAM) or “integrative medicine” (IM) has found a prominent place in medical practice in all too many academic and private medical centers, Dr. Spector got it so wrong that he wasn’t even wrong when he conflated preliminary, hypothesis-generating studies with the big, randomized, phase III clinical trials necessary to achieve FDA approval for a new drug or device. This latest article by Dr. Spector seemed to be of a piece with his previous article in the January/February 2010 issue of SI entitled The War on Cancer A Progress Report for Skeptics, which was so negative in its assessment of scientific progress against cancer that for a moment I was wondering if I were reading or

Unfortunately, Seven Deadly Medical Hypotheses itself is not yet online on the CSI website; so readers without a subscription to SI cannot at the present time judge for themselves whether Mark and I were too harsh on Dr. Spector, but our criticisms, along with that of SBM partner-in-crime Harriet Hall, did have an impact. Seemingly genuinely stunned at the level of criticism leveled at an article published in SI, SI’s editor Kendrick Frazier, to his credit, invited several responses to Dr. Spector’s article, which Harriet Hall, Mark Crislip, Carol Tavris, Avrum Bluming, and I eagerly provided. These letters were originally scheduled to be published a couple of issues ago, along with Dr. Spector’s response. Unfortunately, publishing in dead tree media being what it is, Harriet Hall and I were disappointed to find that the latest issue of SI still didn’t contain our rebuttals. Fortunately, Mr. Frazier has posted this material online for your edification, although, again, I wish he had also published the original article as well.

The College of Physicians and Surgeons of Ontario’s muddled draft policy on “non-allopathic” medicine

Detroit is my hometown, and three and a half years ago, after nearly twenty years away wandering between residency, graduate school, fellowship, and my first academic job, I found myself back in Detroit minted as surgical faculty at Wayne State University and practicing and doing research at the Barbara Ann Karmanos Cancer Institute. One thing that I had forgotten about while I was away for so many years is just how intimately southeast Michigan interacts with Canada. This closeness is not surprising, given that Detroit and Windsor are separated by only about a half mile of Detroit River. Indeed, a there are a lot of Canadians who cross the border on a daily basis to work in the Detroit area, many of them in the medical center within which my cancer center is located. The reason I point this out is not to wax nostalgic for trips to Windsor or for the occasional trip to Stratford to see plays but to point out that Ontario is right next to us. What happens there is of concern to me because I know quite a few people who live there and because it can on occasion influence what goes on over here on the U.S. side of the border.

I recently learned that the College of Physicians and Surgeons of Ontario (CPSO) has been working on updating its policy on the use of nonconventional medical therapies. The wag in me can’t help but wonder why such a policy would need to say anything other than that, if it isn’t science- and evidence-based, the CPSO doesn’t support using it, but in a less sarcastic moment I realized that such a policy is probably not that bad an idea, as long as it doesn’t legitimize pseudoscience, which is, of course, the biggest pitfall to be avoided when writing such a policy. Not too long ago, the CPSO released its draft policy and has asked for public comments, with the deadline being September 1. I was happy to learn that I had not missed the deadline, because there is much to comment about regarding this policy, but it’s definitely true that time’s short. Unfortunately, I wasn’t so happy when I read the title of the draft policy, namely Non-Allopathic (Non-Conventional) Therapies in Medical Practice, with a subtitle of “Formerly named Complementary Medicine.” The full policy in PDF form can be found at this link.
