(Skip to the next section if you want to miss the self-referential blather about TAM.)
As I write this, I’m winging my way home from TAM, crammed uncomfortably—very uncomfortably—in a window seat in steerage—I mean, coach). I had been thinking of just rerunning a post and having done with it, sleeping the flight away, to arrive tanned, rested, and ready to continue the battle against pseudoscience and quackery at home, but this seat is just too damned uncomfortable. So I might as well use the three and a half hours or so left on this flight to write something. If this post ends abruptly, it will be because I’ve run out of time and a flight attendant is telling me to shut down my computer in those cloyingly polite but simultaneously imperious voices that they all seem to have.
I had thought of simply recounting the adventures of the SBM crew who did make it out to TAM to give talks at workshops and the main stage and to be on panels, but that seems too easy. Even easier, I could simply post my slides online. But, no, how on earth can I reasonably expect Mark Crislip to post while he’s at TAM if I’m too frikkin’ lazy to follow suit? I’m supposed to lead by example, right, even if what comes out is nearly as riddled with spelling and grammar errors (not to mention the occasional incoherent sentence) as a Mark Crislip post? Example or not, lazy or not, I would be remiss if, before delving into the topic of today’s post, I didn’t praise my fellow SBM bloggers who were with me, namely Steve Novella, Harriet Hall, and Mark Crislip, for their excellent talks and insightful analysis. Ditto Bob Blaskiewicz, with whom I tag-teamed a talk on everybody’s favorite cancer “researcher” and doctor, Stanislaw Burzynski. It’ll be fun to see the reaction of Eric Merola and all the other Burzynski sycophants, toadies, and lackeys when Bob’s and my talks finally hit YouTube. Sadly, we’ll have to wait several weeks for that. (Hmmm. Maybe I will post those slides later this week.) (more…)
TAM is fast approaching, and I’ve been frantically trying to get my talks together. The theme this year is “Fighting the Fakers,” and one of my talks will be for the Science-Based Medicine Workshop on Thursday, in which I will attempt in a mere 15 minutes to explain what Science-Based Medicine is and how it can be used to combat the infiltration of quackademic medicine into medical academia. Then, the second talk will be a tag-team spectacular with Bob Blaskiewicz about Stanislaw Burzynski as an example of how some cranks skirt the edges of science-based medicine. That doesn’t make them any less dangerous (if anything, it makes them more dangerous), but it does make them not as easy to identify as someone like, say, Hulda Clark.
Unfortunately, between working on these talks, revising some papers, and having an unusually busy weekend on call, I wasn’t sure what I was going to come up with for the edification of you, our readers. Fortunately, right on the 4th of July holiday, there was an article that gave me my idea, particularly given that I had noticed a couple of studies on the very subject of the article in the week leading up to the long holiday in the US (at least for people not on call). As a result, I’m half tempted to refer to this article as a trilogy of acupuncture terror.
Well, the latest round of grant applications and pre-applications is finally over, which gave me time this weekend to peruse the stack of journals that’s been accumulating on my desk. Oddly enough, despite my being about as plugged in as you can be at my age, I’m still old-fashioned enough to enjoy the physical sensation and the overall experience of picking up the most recent issue of a journal and randomly flipping through it. There’s something about the feel of the paper, the smell of the coating and print, as well as the sheer undirectedness of it all. It’s how I find articles that I probably would never find if I relied just on perusing the table of contents of an electronic edition.
Sadly, that’s not how I found this week’s topic. The study that I’m going to discuss this week is an E-pub ahead of print that I became aware of through a Reuters story, late last week when I still didn’t have time to deal with it. As is my usual practice, I saved the link for later in Safari’s Reading List, and this time I actually managed to come back to it. The story is entitled “Many cancer patients expect palliative care to cure“, and it’s about a recent publication out of the Dana-Farber Cancer Institute published online in the Journal of Clinical Oncology (JCO) entitled “Expectations About the Effectiveness of Radiation Therapy Among Patients With Incurable Lung Cancer“. It caught my eye, even a week ago, because managing expectations in patients with advanced cancer. It then led me to do a search for related articles, which brought me to a similar study from last fall in the New England Journal of Medicine, entitled “Patients’ Expectations about Effects of Chemotherapy for Advanced Cancer“, also from the same group at the Dana-Farber. This latter study looked at patients’ expectations regarding chemotherapy, and I even remember having encountered it when it was first published and wanted to blog about it then. I don’t recall why I didn’t, but here’s my chance to revisit it. (more…)
Every so often, the reality of trying to maintain a career in science-based medicine interferes with the fun that is writing for this blog. Basically, what happened is that I spent the entire weekend working on three different grant applications and, by the time Sunday night rolled around, I was too exhausted to write what I had originally planned on writing. Fortunately, one advantage of having been blogging so long and also having blogged under a pseudonym over at my not-so-super-secret other blog is that there’s a lot of material which is pretty damned good, if I do say so myself, that I can draw on for just these situations. Even better, it’s old enough that it’s unlikely that most of you have actually come across it before, which makes it new to you (well, at least most of you). As a special bonus, the jumping off point was a post by an occasional contributor to this blog, Peter Lipson. Actually, I wish Peter would contribute more regularly, but he’s too busy moving on to bigger things at Forbes.
This time around, I’m half-recycling, half-revising a post that was a bit more navel-gazing than usual. However, as the only surgeon on SBM I think it’s actually useful every now and then to discuss the trials and tribulations of practicing science-based surgery. It began when Peter wrote an excellent meditation on a topic that’s always been a difficult issue for me to face as a surgeon, namely how one balances confidence in one’s ability with humility in the face of disease and uncertain science. He started with a spot-on observation:
The practice of medicine requires a careful mix of humility and confidence. Finding this balance is very tricky, as humility can become halting indecision and confidence can become reckless arrogance. Teaching these traits is a combination of drawing out a young doctor’s natural strengths, tamping down their weaknesses, and tossing in some didactic knowledge.
Sometimes, between blogging, a demanding day (and night) job doing surgery and science, and everything else, I embarrass myself. Sure, sometimes I embarrass myself by saying something that, in retrospect, I wish I hadn’t. More often, I embarrass myself by letting things slide that I shouldn’t. For instance, when friends send me a prepublication copy of their books, I should damned well read them, don’t you think? So it was that Paul Offit sent me a copy of his latest book, which just hit the bookstores and online outlets this week, Do You Believe in Magic? The Sense and Nonsense of Alternative Medicine, and I haven’t finished it. Oh, I’ve read a good chunk of it, but it’s not a huge book (around 335 pages); so I should have finished it by now, particularly since it’s quite good. My failure to properly read and plug the book aside, I’m glad to see that the book’s getting attention in a large media outlet, namely USA Today, in an article by Liz Szabo Book raises alarms about alternative medicine. There’s also a companion piece How to guard against a quack. I figure that the least I can do is to plug Dr. Offit’s book and the USA Today story in which he is featured, just as Harriet plugged his recent speaking appearance.
It’s also nice that Steve Novella and I were both interviewed. Now, excuse me while I get back to doing what I really should have had finished a month or two ago: Reading Dr. Offit’s excellent book.
I never used to write much about genetically modified organisms (GMOs) before. I still don’t do it that often. For whatever reason, it just hasn’t been on my radar very much. That seems to be changing, however. It’s not because I went seeking this issue out (although I must admit that I first became interested in genetic engineering when I was in junior high and read a TIME Magazine cover article about it back in the 1970s), but rather because in my reading I keep seeing it more and more in the context of anti-GMO activists using bad science and bad reasoning to justify a campaign to demonize GMOs. Now, I don’t have a dog in this hunt, (Forgive me, I have no idea why I like that expression, given that I don’t hunt.) I really don’t. I was, not too long ago, fairly agnostic on the issue of GMOs and their safety, although, truth be told, because I have PhD in a biomedical science and because my lab work has involved molecular biology and genetics since I was a graduate student in the early 1990s, I found the claims of horrific harm attributable to GMOs not particularly convincing, but hadn’t bothered to take that deep a look into them. It was not unlike my attitude towards the the claims that cell phones cause cancer a few years ago, before I looked into them and noted the utter lack of a remotely-plausible mechanism and uniformly negative studies except for a group in Sweden with a definite ax to grind on the issue. Back then, I realized that there wasn’t really a plausible mechanism by which radio waves from cell phones could cause cancer in that the classic mechanisms by which ionizing radiation can break DNA molecular bonds and cause mutations don’t apply, but I didn’t rule out a tiny possibility that there might be an as-yet unappreciated mechanism by which long term exposure to radio waves might contribute to cancer. I still don’t, by the way, which has gotten me into the odd kerfuffle with some skeptics and one physicist, but I still view the likelihood that cell phone radiation can cause cancer as being just a bit more plausible than homeopathy.
As was the case for the nonexistent cell phone-cancer link, there has now been a steady drip-drip-drip of bad studies touted by anti-GMO activists as “evidence” that GMOs are the work of Satan that will corrupt or kill us all (and make us fat, to boot). Not too long ago, I came across one such study, a truly execrable excuse for science by Gilles-Eric Séralini at the University of Caen purporting to demonstrate that Roundup-resistant genetically modified maize can cause horrific tumors in rats. I looked at the methods and conclusions and what I found was some of the worst science I had ever seen, every bit as bad as the quack “science” used by the antivaccine movement. It wasn’t for nothing that I made the comparison, because the anti-GMO movement is very much like the antivaccine movement and the cranks who claim that cell phone radiation causes cancer. As if to demonstrate that very point, last week I came across an article by the all-purpose crank to rule all cranks, Mike Adams, at NaturalNews.com entitled GMO feed turns pig stomachs to mush! Shocking photos reveal severe damage caused by GM soy and corn: (more…)
Editor’s note:This is an extra “bonus” post. Basically, it’s a revised version of a post I did at my not-so-super-secret-other-blog last week. The issue, however, has disturbed me so much that I felt it appropriate to post it to SBM as well. Fear not. There will be a new post by yours truly on Monday.
Sometimes, in the course of blogging, I come across a story that I don’t know what to make of. Sometimes, it’s a quack or a crank taking a seemingly science-based position. Sometimes it’s something out of the ordinary. Other times, it’s a story that’s just weird, such that I strongly suspect that something else is going on but can’t prove it. So it was a few months ago when I came across the story of Alex Spourdalakis, a 14-year-old autistic boy who became a cause célèbre of the antivaccine crank blog Age of Autism.
I first noticed the story in early March when perusing AoA and came across a post by Lisa Goes entitled Day 19: Chicago Hospital Locks Down Autistic Patient. In the post was a shocking picture of a large 14-year-old boy in a a hospital bed in four-point restraints. He was naked, except for a sheet covering his genitals. A huge gash was torn in the bedsheet, revealing the black vinyl of the hospital bed beneath. The boy’s name, we were informed, was Alex Spourdalakis. Further down in the post was another, equally shocking, picture of Alex that, according to Goes, showed severe dermatitis on Alex’s back due to the hospital sheets. The photos shocked me for two reasons. First, if the story was as advertised (something always to be doubted about any story posted at AoA), for once I thought that I might be agreeing with Goes and thinking that AoA was actually doing a good thing, as disconcerting as that possibility was to me. Second, however, I was extremely disturbed by the publication of such revealing photos of the boy. Undoubtedly, Alex’s mother must have given permission. What kind of mother posts pictures like that of her son for all the world to see? Then there appeared a Facebook page, Help Support Alex Spourdalakis, which pled for readers to help the Spourdalakis family.
As I said, something just didn’t seem right at the time. (more…)
Last week, I reviewed a long-expected (and, to some extent, long-dreaded) documentary by Eric Merola, a filmmaker whose talent is inversely proportional to his yen for conspiracy, pseudoscience, and quackery. Through a quirk of fate that couldn’t have worked out better if I had planned it myself, a long-expected investigation of the Burzynski Clinic by the BBC aired on its venerable news program Panorama last Monday. It was entitled, appropriately enough, Cancer: Hope for Sale? Ever since learning that the BBC was working on this back in January or February, skeptics have been looking forward to it with a mixture of anticipation and dread, anticipation because we expected that the Panorama crew would “get it” (in the interests of full disclosure, I will mention that I was interviewed over the phone by a Panorama producer and exchanged e-mails to answer questions and suggestions), but a bit of dread because we feared the bane of all news reporting on issues of science and medicine: false balance.
So now that the report was finally aired, how was it? You can either watch it on iPlayer (if you’re in the UK) or on YouTube (if you’re not, assuming it’s still there):
Well, I’ve finally seen it, and it was even worse than I had feared.
After having heard of Eric Merola’s plan to make a sequel to his 2010 propaganda “documentary” about Stanislaw Burzynski, Burzynski The Movie: Cancer Is Serious Business, which I labeled a bad movie, bad medicine, and bad PR, I’ve finally actually seen the finished product, such as it is. Of course, during the months between when Eric Merola first offered me an “opportunity” to appear in the sequel based on my intense criticism of Burzynski’s science, abuse of the clinical trials process, and human subjects research ethics during the last 18 months or so, there has been intense speculation about what this movie would contain, particularly given how Merola’s publicity campaign involved demonizing skeptics, now rechristened by Merola as “The Skeptics,” a shadowy cabal of people apparently dedicated (according to Merola) to protecting big pharma and making sure that patients with deadly cancers don’t have access to Burzynski’s magic peptides, presumably cackling all the way to the bank to cash those big pharma checks.

I am taking the Memorial Day holiday off. I will return next week (or even earlier if something comes up that I can’t resist blogging about). In the meantime, here’s a general principle that needs to be remembered in cancer research:
I would also add to that list: So does bleach. So does acid. So does alkali. So does pouring the media out of the dish and letting the cells dry out. So do a variety of lethal poisons. So does heat. So does cold. The list goes on.
The point, of course, is that it’s very easy to kill cells in a cancer dish. What is difficult is selectively killing cancer cells in the human body while not harming normal cells.
