[Part One of “Genetic Gamble: New Approaches to Fighting Cancer.”] After a Leukemia doctor and researcher develops the disease himself, he finds an effective treatment when his colleagues sequence his cancer genome:

“Dr. Wartman’s doctors realized then that their last best hope for saving him was to use all the genetic know-how and technology at their disposal.

“After their month of frantic work to beat cancer’s relentless clock, the group, led by Richard Wilson and Elaine Mardis, directors of the university’s genome institute, had the data. It was Aug. 31.

“The cancer’s DNA had, as expected, many mutations, but there was nothing to be done about them. There were no drugs to attack them.

“But the other analysis, of the cancer’s RNA, was different. There was something there, something unexpected.”
