 * Stage IIIA: tumor invades serosa or adnexa, or malignant peritoneal cytology
 * Stage IIIB: vaginal metastasis
 * Stage IIIC: metastasis to pelvic or para-aortic lymph nodes
 * Stage IVA: invasion of the bladder or bowel
 * Stage IVB: distant metastasis, including intraabdominal or inguinal lymph nodes
