A 55-year-old post-menopausal woman presents with a 10 cm right ovarian mass, omental caking on CT, and CA-125 of 650 U/mL. Intraoperative finding shows contiguous spread to the sigmoid colon requiring resection. According to FIGO 2014, this is staged as:
- A Stage IIIC ✓
- B Stage IIIA2
- C Stage IIIB
- D Stage IVB
Correct answer: A. Stage IIIC
Explanation
FIGO 2014 Stage IIIC ovarian cancer is defined by peritoneal metastases beyond the pelvis and/or metastasis to retroperitoneal lymph nodes greater than 2 cm, and includes macroscopic peritoneal metastases beyond the pelvis more than 2 cm with or without lymph node involvement. Omental caking and sigmoid colon involvement by direct spread represent Stage IIIC. Stage IVB would require distant organ metastases (parenchymal liver, lung, groin nodes).
