Phase I Study of Intravenous Triapine (IND # 68338) in Combination With Pelvic Radiation Therapy With or Without Weekly Intravenous Cisplatin Chemotherapy for Locally Advanced Cervical, Vaginal, or Pelvic Gynecologic Malignancies

Drugs used in chemotherapy, such as 3-AP and cisplatin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. 3-AP may also stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Radiation therapy uses high-energy x-rays to kill tumor cells. 3-AP and cisplatin may make tumor cells more sensitive to radiation therapy. Giving 3-AP and external-beam radiation therapy together with cisplatin may kill more tumor cells. This phase I trial is studying the side effects and best dose of 3-AP when given together with external-beam radiation therapy with or without cisplatin in treating patients with gynecologic cancer
