After completing 4 treatments of chemotherapy, participants will have blood and urine tests, a chest x-ray to learn the response of the tumor to the chemotherapy. They will also have a CT scan of the abdomen and pelvis. Participants who have a response to the chemotherapy, or show no sign of new spread of the cancer to other parts of the body, will then have surgery. Surgery will be done to remove the tumor. The lymph nodes in the groin will be removed. The pelvic lymph nodes may also need to be removed. How much tissue is removed depends on how far the tumor has spread. The surgeons will explain the specifics of the surgery in a separate consent form.
