Gemzar is a chemotherapy drug that is given as a treatment for some types of cancer. It is most commonly used to treat non-small cell lung cancer, pancreatic, bladder and breast cancer. The goal of chemotherapy with Gemzar is to kill as many cancer cells as possible or to stop them from dividing and making more cancer cells. Gemzar works by interfering with the process by which cells divide and repair themselves, thus preventing the further growth of cancer cells and leading to cell death. In a clinical study of Gemzar in patients with pancreatic cancer, nearly one in five patients was alive one year after diagnosis as compared with one in 50 patients given the comparison chemotherapy with drugs formerly given to cancer patients before GEMZAR was available.
