Bar Harbor, Me—The National Cancer Institute (NCI) is launching a major effort aimed at revolutionizing how tumors are classified, a venture that has far-reaching implications for how physicians will diagnose and treat cancer in the future.

A refined classification scheme that will reflect important differences in the molecular makeup of tumors—differences that are mostly unknown to today's pathologists—will help researchers find better ways to prevent and treat various forms of cancer, said NCI Director Richard Klausner, MD. He described the initiative at a press briefing held here in connection with a conference on "The Genetics Revolution in the New Millennium," sponsored by the Jackson Laboratory and Johns Hopkins University.

What makes this pioneering effort possible is the torrent of genetic information pouring out of the Human Genome Project, along with the development of DNA microarrays (or "DNA chips"), a powerful new technology that provides a window . . . [Full Text of this Article]
