A 55-year-old postmenopausal woman has a 9 cm right ovarian complex cyst with solid components, bilateral involvement, ascites, and CA-125 of 680 U/mL. Surgery reveals a papillary serous adenocarcinoma with omental cake but no extra-abdominal spread. Histology confirms high-grade serous carcinoma. What is the FIGO 2014 staging?
- A Stage IIIA2
- B Stage IIIC ✓
- C Stage IIIB
- D Stage IVB
Correct answer: B. Stage IIIC
Explanation
FIGO 2014 stage IIIC denotes peritoneal metastasis beyond the pelvis measuring >2 cm in greatest dimension, including the omentum, and/or retroperitoneal lymph node metastasis. An omental cake (>2 cm peritoneal deposit) without extra-abdominal spread = stage IIIC. Stage IIIA2 has microscopic peritoneal implants; IIIB has macroscopic implants ≤2 cm; Stage IV requires pleural effusion with cytology, liver/spleen parenchymal metastases, or extra-abdominal spread.
