    Stages cancer of the ovary, fallopian tube, and peritoneum.

    When to Use
    Pearls/Pitfalls

    Use postoperatively in patients with histologically-proven ovarian cancer (surgical pathology is needed in order to stage).

    • Stage IB (bilateral involvement) is uncommon and only occurs in 1-5% of stage I cases (Heintz 2006). Large stage IB ovarian tumors associated with a contralateral normal‐size ovary with small superficial tumor foci suggest the latter are metastatic (⅓ of stage I tumors with bilateral involvement look like this) (Prat 2013).

    • Controversy exists around whether positive lymph nodes (macroscopic) above the renal vessels should be considered stage III or IV, and are not addressed by the current guidelines.

    Tumor confined to ovaries
    Tumor involves 1 or both ovaries with pelvic extension (below the pelvic brim) or primary peritoneal cancer
    Tumor involves 1 or both ovaries with cytologically or histologically confirmed spread to the peritoneum outside the pelvis and/or metastasis to the retroperitoneal lymph nodes
    Distant metastasis excluding peritoneal metastasis
