Prostate cancer topics abound in the latest Cancer News Review podcast. Dr. Bill Nelson, director of the Johns Hopkins Kimmel Cancer Center, discusses Hopkins-led research, published in the New England Journal of Medicine, looking at the genetic similarities of men with a family history of prostate cancer. By looking at their genes, investigators were able to find a genetic marker for prostate cancer risk. Nelson also comments on a study of prostate cancer screening methods that evaluated impact on lives saved and new statistics released by the National Cancer Institute.
Reacting to an opinion piece written about proton beam therapy, Nelson asks the same question of the the more costly therapy: is it better than conventional radiation? He says the answer is not clear. There is a lack of research comparing conventional and proton beam therapy, and still, the therapy is being used for many cancers. Nelson says the field is ready for more research on this topic.
