Nature last spoke in-depth with Harold Varmus in July, 2011, one year after he became director of the $5 billion National Cancer Institute (NCI), the largest of the 27 institutes and centres at the National Institutes of Health. (NIH).
Today, in a rare press conference, Varmus, who directed the entire NIH from 1993 to 1999, spoke to a crowd of 75 at the National Press Club in downtown Washington, DC. His advertised theme was the obstacles — biological, economic, institutional, cultural — to making bigger strides against cancer.
Varmus, who in 1989 shared a Nobel Prize for his studies on the genetic basis of cancer, applauded what he called the “extraordinary” recent advances in our understanding of cancer biology, and in the scientific and computational toolkits we can now deploy against it. Still, he noted, cancer mortality rates have been stubbornly slow to decline and some of the most enticing targets for therapies have not yet yielded breakthroughs. He pointed, by way of example, to KRAS, a gene known for nearly thirty years to be mutated in roughly one-third of all cancers — knowledge that so far has not led to an effective, targeted therapy.
“I remain an optimist,” he said, but “we have to temper expectations.”
Varmus also reported on the bleak success rate for scientists seeking funding from the NCI: it is at a historic low of 14%. The picture is not much rosier for the whole of NIH: the average success across all institutes and centers is only 17%.
Varmus took a wide range of questions after his prepared remarks. Here, edited for brevity, are his responses to a few of them.
