A Quick List of Precision Oncology Skeptics

Just a few days after a major report of ten oncology initiatives was produced by the Cancer Moonshot advisors (here), Derek Lowe blogged at SCIENCE about a pair of skeptical articles on precision oncology, written this year by Vinay Prasad in Nature and Lancet.   A quick set of links for the curious.  Further below, a short roster of some other precision medicine skeptic articles.

Update:  This blog is from September 2016; for a one-time update in May 2018, here.

As an entry to earlier citations, see a blog on "hope and hype" in precision medicine, from August 2015 -  here.  See also Joyner's anti-Moonshot op ed in  the January 2015 NYT here, and blog follow ups here, here.

For a parallel idea that comes from outside the mainstream "precision medicine" space, in clinical genetics there is a growing literature on defining "missing heritability" - the gap between genetics and phenotype.  There are clearly crosswalks between this idea in the field of biology/clinical genetics and the concern that genomics alone will only get us so-far in curing cancers.   For an open access entry point, see Blanco-Gomez, Bioessays 2016, here; see also a search of Pubmed for the phrase "missing heritability" in article titles (79 hits as of 10/1/2016).  However, be aware that even the skeptical idea of "missing heritability" has its own skeptics (!), here.

For an example of a recent, highly positive news article in the San Diego Union, see here.  For a 16p state of the art precision medicine review article, in Nature Reviews Genetics by Stanford's Euan Ashley, see here (linked from the San Diego Union news article; Nature article 9/2016).
