A 62-year-old woman undergoes staging laparotomy for ovarian carcinoma. Intraoperative findings: bilateral ovarian masses with surface excrescences, peritoneal deposits in the pelvis only, and omental biopsy negative for tumour. According to FIGO 2014 staging, what stage is this?

• A FIGO Stage IC2
• B FIGO Stage IIB ✓
• C FIGO Stage IIIA1
• D FIGO Stage IIC

Explanation

FIGO 2014 ovarian cancer staging: Stage II = tumour involving one or both ovaries with pelvic extension. Stage IIB = extension to other pelvic peritoneal tissues (pelvic peritoneal deposits beyond the ovary). Stage IC involves capsule rupture or surface involvement of the primary tumour only, not peritoneal extension. Stage IIIA1 requires positive retroperitoneal nodes or microscopic extrapelvic peritoneal metastasis. IIC no longer exists in the 2014 revision.
