A 55-year-old postmenopausal woman undergoes staging laparotomy for a serous ovarian carcinoma. Histology shows tumour involving the left ovary only, with capsule intact, no ascites, and negative peritoneal washings. According to FIGO 2014 staging, her stage is:
- A Stage IB
- B Stage IC1
- C Stage IA ✓
- D Stage IC3
Correct answer: C. Stage IA
Explanation
FIGO 2014 Stage IA: tumour limited to one ovary, capsule intact, no tumour on ovarian surface, no malignant cells in ascites or peritoneal washings. Stage IC is subdivided into IC1 (surgical spill), IC2 (capsule rupture before surgery or tumour on surface), and IC3 (positive washings). With intact capsule and negative washings, Stage IA is correct.
