Malignant Mixed Mesodermal Tumor (MMMT) - Early Stage With Postoperative XRT/Chemotherapy

Study Overview
=================
Brief Summary
-----------------
Primary Objectives: To test whether the addition of chemotherapy to radiotherapy improves the progression-free survival for patients with stage I, II and IIIa malignant mixed mesodermal tumor (MMMT) of the uterus. To determine the acute and late toxicity profiles associated with this treatment regimen. To describe the effect of this treatment regimen on the patient's quality of life.

Detailed Description
-----------------
Patients in this study will have an operation to remove their uterus, tubes, and ovaries with biopsies of the omentum and lymph nodes before entering this study. Before treatment starts, patients will have a chest x-ray, computed tomography (CT) scan, blood tests, and a physical exam. Patients who have a history of hearing loss will have a hearing test. Within 8 weeks after surgery, patients will receive 5 weeks of combination radiation therapy and cisplatin chemotherapy. Radiation and cisplatin will be given on Day 1 or day 2 of each week followed by 4 days of radiation alone. An additional dose of radiation, directed at the surface of the vagina, will be given either during the last week (Week 5) of treatment or after the radiation and cisplatin chemotherapy is finished. Three to five weeks after radiation therapy and cisplatin chemotherapy is finished, patients will receive additional chemotherapy. Carboplatin and paclitaxel will be given every 28 days for 4 cycles. All chemotherapy is given into the vein through a catheter (tube). Patients will be taken off study if their disease gets worse or intolerable side effects occur. Patients will be seen one month after the last cycle of chemotherapy, then every 3-4 months from then on for 2 years. At each visit, patients will have blood tests and a physical exam. Computed tomography (CT) scans will be ordered only if it is suspected that the disease has come back. All patients will be followed for a maximum of 2 years after their therapy is completed. This is an investigational study. Cisplatin, Carboplatin and Paclitaxel are FDA approved and commercially available. A total of 49 patients will take part in this study. Up to 25 patients may be enrolled at M. D. Anderson Cancer Center in Houston, up to 12 patients will be enrolled at MD Anderson Cancer Center, Orlando, and up to 12 patients will be enrolled at the University of Texas Medical Branch in Galveston.
