NCI: The tumor is found in one or both ovaries and has spread to other parts of the abdomen. Stage III is divided into stage IIIA, stage IIIB, and stage IIIC. In stage IIIA, the tumor is found only in the pelvis, but tumor cells have spread to the surface of the peritoneum (tissue that lines the abdominal wall and covers most of the organs in the abdomen). In stage IIIB, the tumor has spread to the peritoneum but is 2 centimeters or smaller in diameter. In stage IIIC, the tumor has spread to the peritoneum and is larger than 2 centimeters in diameter and/or has spread to lymph nodes in the abdomen. The spread of tumor cells to the surface of the liver is considered stage III disease.,NCI: Stage III includes: T3, N0, M0. T3: Tumor involves one or both both ovaries with microscopically confirmed peritoneal metastasis outside pelvis. N0: No regional lymph node metastasis. M0: No distant metastasis.
