While social media and news outlets were reacting, or in some cases overreacting, to a new rodent-based medical study on the unlikely link between cell phone use and brain cancer last month, two studies and an accompanying commentary were quietly published in Pediatrics that raised similar concerns. Rather than cell phone use, the proposed potential cause of pediatric cancer in these newly published papers was phototherapy, a common treatment for newborn jaundice that I use regularly and have written about before. My previous post has a full review of jaundice in the newborn, how it can potentially cause permanent brain damage, and why phototherapy is a safe and effective treatment in most cases.
But is phototherapy truly safe? Can exposure to a narrow spectrum of blue light increase the risk of cancer in young children? And if so, what type or types of cancer? This is exactly what the study authors set out to investigate using the power of “Big Data.” Time will eventually tell us if the authors’ conclusions are justified or if they will end up only serving as excellent future examples of the Texas Sharpshooter Fallacy.

I was contemplating writing a post along the same lines as Harriet’s post about evolutionary medicine last week, but then on Sunday morning I saw an article that piqued my interest. Sorry, Harriet, my response, if I get to it, might have to wait until next week, although we could always discuss the usefulness (versus the lack thereof) of evolutionary medicine over a beer or two at The Amazing Meeting in a few days. In the meantime, this week’s topic will revisit a topic near and dear to my heart, a topic that I tend to view (sort of) in a similar way as Harriet views evolutionary medicine, namely personalized medicine or the “individualization” of treatments. It’s a topic I’ve written about at least twice before and that Brennen McKenzie wrote about just last week. In essence, we both pointed out that when it comes to “complementary and alternative medicine” (CAM) or “integrative medicine” treatments for various conditions and diseases, what CAM practitioners claim to be able to do with respect to “individualized care” is nonsense based on fantasy. Science-based medicine already provides individualized care, but it’s individualized care based on science and clinical trials, not tooth fairy science.
Serendipitously, this point was driven home over the weekend in an article by Gina Kolata in the New York Times entitled In Treatment for Leukemia, Glimpses of the Future. While the story is basically one long anecdote that shows what can be done when new genomic technologies are applied to cancer, it also shows why we are a very long way from the true “individualization” of cancer care. It also turns out that I’ve discussed the same basic story before, but here I’ll try to discuss it in a bit more detail.
