Stage Information for Ovarian Epithelial Cancer

    Table 1. Carcinoma of the Ovarya

    Stage
    a Adapted from FIGO Committee on Gynecologic Oncology.[8]
    b In order to evaluate the impact on prognosis of the different criteria for allotting cases to stage Ic or IIc, it would be of value to know if rupture of the capsule was spontaneous, or caused by the surgeon; and if the source of malignant cells detected was peritoneal washings, or ascites.
    IGrowth limited to the ovaries.
    IaGrowth limited to one ovary; no ascites present containing malignant cells. No tumor on the external surface; capsule intact.
    IbGrowth limited to both ovaries; no ascites present containing malignant cells. No tumor on the external surfaces; capsules intact.
    IcbTumor either stage Ia or Ib, but with tumor on surface of one or both ovaries, or with capsule ruptured, or with ascites present containing malignant cells, or with positive peritoneal washings.
    IIGrowth involving one or both ovaries with pelvic extension.
    IIaExtension and/or metastases to the uterus and/or tubes.
    IIbExtension to other pelvic tissues.
    IIcbTumor either stage IIa or IIb, but with tumor on surface of one or both ovaries, or with capsule(s) ruptured, or with ascites present containing malignant cells, or with positive peritoneal washings.
    IIITumor involving one or both ovaries with histologically confirmed peritoneal implants outside the pelvis and/or positive regional lymph nodes. Superficial liver metastases equals stage III. Tumor is limited to the true pelvis, but with histologically proven malignant extension to small bowel or omentum.
    IIIaTumor grossly limited to the true pelvis, with negative nodes, but with histologically confirmed microscopic seeding of abdominal peritoneal surfaces, or histologic proven extension to small bowel or mesentery.
    IIIbTumor of one or both ovaries with histologically confirmed implants, peritoneal metastasis of abdominal peritoneal surfaces, none exceeding 2 cm in diameter; nodes are negative.
    IIIcPeritoneal metastasis beyond the pelvis >2 cm in diameter and/or positive regional lymph nodes.
    IVGrowth involving one or both ovaries with distant metastases. If pleural effusion is present, there must be positive cytology to allot a case to stage IV. Parenchymal liver metastasis equals stage IV.
