I found this website, when I searched for information about primary peritoneal cancer, a truely silent killer. My younger sister was diagnosed with PPC in May 2006. Her CA125 was 5000. She had one round of chemo as well as intraperitoneal chemo before her sugery, followed by 8 more rounds of chemo. Her CA125 was 8 after the last chemo in February. Three months ago, her CA125 was 15, still within the normal range. Three weeks ago her CA125 was 36.3 (normal = 35), but last week it elevated to 42. The doctor did not see any tumor from her abdominal ultrasound, so that her oncologist asked her to wait for one month before he could make his decision about chemo. Has anyone here have similar experience? I am terrified about her cancer's coming back. It's only been 6 months since her last chemo! I would like to know if there is any complementary treatment such as nutrition supplement/herbal therapy available for this cancer. I know that we still need to rely on the conventional treatment like surgery and chemo to treat the cancer, but I just wonder if there is any complementary therapy that can help to fight the cancer.
