 Unfortunately, Avastin can cause some dangerous side effects in women with advanced cancer. For instance, it can cause a hole in the intestines, and can increase the risk of blood clots and strokes. Avastin has not been given at the same time as IP therapy, so it is not known if this is a safe or effective combination. In this study, IV Avastin will be given in addition to IP cisplatin, IP Taxol, and IV Taxol, to patients like you who have not had any chemotherapy before. This study aims to find out what effects, good andor bad, that this combination of drugs has on your body and on your type of cancer.
