Immunotherapy: How the Immune System Fights Cancer

The National Cancer Institute (NCI), the largest institute of the National Institutes of Health (NIH), recently posted a short (3-4 minute) but very illustrative video showing and describing three ways how our immune system fights cancer. These methods include: a) non-specific immune stimulation, as illustrated in bladder cancer; b) T-cell transfer therapy, somewhat similar to how Provenge works against prostate cancer; and, c) immune checkpoint inhibitors, such as Keytruda and Opdivo, currently the subject of many combinatorial clinical trials against several types of cancer including prostate cancer. This video appeared in the July 11th, 2018 e mail edition of Cancer Information Highlights from the National Cancer Institute, to which one can subscribe at
