Molecules of sugar sitting on the surface of cancer cells are keys to the development of a new vaccine aimed at both treating and stopping the spread of certain types of cancers called carcinomas, which include prostate, breast, ovarian and lung, among others. Armed with a new two-year grant for $600,000 from the Gateway for Cancer Research, an Illinois-based philanthropic foundation, immunologist Alessandra Franco, M.D., Ph.D., and her co-workers at the Moores Cancer Center at the University of California, San Diego are hoping to develop a low-cost immunotherapy for prostate carcinoma that may also have use against a variety of other carcinomas as well.
