title: Cancer treatment: what's ahead?
abstract: Surgery, chemotherapy, and radiation therapy are standard modalities for cancer treatment. Biological therapy (immunotherapy, biotherapy, or biological response modifier therapy) is a comparatively novel addition to this armamentarium. Biological therapies use the body's immune system, either directly or indirectly, to fight cancer or to lessen the side effects that may be caused by some cancer treatments. Biological therapeutic agents include interferons, interleukins, colony-stimulating factors, monoclonal antibodies, vaccines, gene therapy, and nonspecific immunomodulating agents. A promising form of cancer treatment is immunotherapy. Immunotherapy for cancer is essentially the stimulation of the immune system through a variety of reagents such as vaccines, infusion of T-cells, or cytokines. These reagents act through one of several mechanisms including stimulating the anti-tumor response, decreasing suppressor mechanisms, altering tumor cells to increase their immunogenicity and making them more susceptible to immunologic defenses, and improving tolerance to cytotoxic agents or radiotherapy. This review describes some novel approaches in the immunotherapy in cancer.
