Ovarian Low Malignant Potential Tumors Treatment (PDQ®): Treatment - Patient Information [NCI] - Stages of Ovarian Low Malignant Potential Tumors


Stage III

Pea, peanut, walnut, and lime show tumor sizes.

In stage III, the tumor is found in one or both ovaries and has spread outside the pelvis to other parts of the abdomen and/or nearby lymph nodes. Stage III is divided into stage IIIA, stage IIIB, and stage IIIC.

  • Stage IIIA: The tumor is found in the pelvis only, but tumor cells that can be seen only with a microscope have spread to the surface of the peritoneum (tissue that lines the abdominal wall and covers most of the organs in the abdomen), the small intestines, or the tissue that connects the small intestines to the wall of the abdomen.
  • Stage IIIB: The tumor has spread to the peritoneum and the tumor in the peritoneum is 2 centimeters or smaller.
  • Stage IIIC: The tumor has spread to the peritoneum and the tumor in the peritoneum is larger than 2 centimeters and/or has spread to lymph nodes in the abdomen.

The spread of tumor cells to the surface of the liver is also considered stage III disease.

Stage IV

In stage IV, tumor cells have spread beyond the abdomen to other parts of the body, such as the lungs or tissue inside the liver.

Tumor cells in the fluid around the lungs is also considered stage IV disease.

Ovarian low malignant potential tumors almost never reach stage IV.
