Ovarian Cancer Vaccine Made From Tumors Yields Responses, University of Pennsylvania Study

Scientists have crafted an experimental vaccine against advanced ovarian cancer that was safe and triggered an immune response using muscled-up blood cells primed by tumors that were taken from the patients. It took 7 days to make the injection individually for each woman, according to a report today at the American Association for Cancer Research meeting in Washington. The therapeutic vaccine was the first step in a two-part process that involved teaching the woman’s blood cells to recognize the cancer, then infusing an army of her own infection-fighting immune system cells to attack the tumor. The study was the first clinical trial of this new approach.
