Researchers develop successful test vaccine that prevents development of prostate cancer.
PHILADELPHIA - Researchers at the University of Southern California have developed a prostate cancer vaccine that prevented the development of cancer in 90 percent of young mice genetically predestined to develop the disease. In the February 1 issue of Cancer Research, they suggest the same strategy might work for men with rising levels of PSA (prostate specific antigen), a potential diagnostic indicator of prostate cancer.
Now, men with rising PSA levels but no other signs of cancer are advised "watchful waiting" - no treatment until signs of the cancer appear, Kast says. "But what if instead of a watchful wait, we vaccinate? That could change the course of the disease"
