Patient's own infection-fighting T cells put late-stage melanoma into long-term remission

Case is first to show safety and effectiveness of using cloned cells alone to kill tumors
Researchers describe the first successful use of a human patient's cloned infection-fighting T cells as the sole therapy to put an advanced solid-tumor cancer into long-term remission. A team led by Cassian Yee, M.D., an associate member of the Clinical Research Division at Fred Hutchinson Cancer Research Center, reports these findings in the June 19 issue of the New England Journal of Medicine.
