Docetaxel and Capecitabine in Treating Patients With Recurrent or Persistent Ovarian Epithelial Cancer, Fallopian Tube Cancer, or Peritoneal Cavity Cancer

RATIONALE: Drugs used in chemotherapy, such as docetaxel and capecitabine, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving docetaxel together with carboplatin may kill more tumor cells. PURPOSE: This phase II trial is studying how well giving docetaxel together with capecitabine works in treating patients with recurrent or persistent ovarian epithelial cancer, fallopian tube cancer, or peritoneal cavity cancer.
