Paclitaxel and Carboplatin With or Without Bevacizumab in Treating Patients With Stage II, Stage III, or Stage IV Ovarian Epithelial Cancer, Primary Peritoneal Cancer, or Fallopian Tube Cancer

This phase III clinical trial studies two different dose schedules of paclitaxel to see how well they work in combination with carboplatin with or without bevacizumab in treating patients with stage II, III or IV ovarian epithelial cancer, primary peritoneal cancer, or fallopian tube cancer. Drugs used in chemotherapy, such as paclitaxel and carboplatin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Bevacizumab is a type of drug called a monoclonal antibody and blocks tumor growth by stopping the growth of blood vessels that tumors need to grow. It is not yet known whether giving paclitaxel with combination chemotherapy once every three weeks is more effective than giving paclitaxel once a week in treating patients with ovarian, primary peritoneal, or fallopian tube cancer.
