I just found this website. my mom was diagnoised 2 years ago with pertoneal carcinoma. she is in her 2nd year of chemo treatments. 1st year was conventional chemo and the last year she is on research treatments. Her # has fluxuated from 91 to 1700 in the last 2 years. She was told there is nothing to do surgury on, because all of her cancer is in the fluid and not in the lining or in the wall. Is there hope?
