According to FIGO 2014 staging for ovarian cancer, Stage IC2 is defined as:
- A Tumour limited to one ovary with malignant cells in ascites
- B Tumour limited to one ovary with surgical spill during surgery
- C Tumour limited to one ovary with capsule ruptured before surgery ✓
- D Tumour involving both ovaries with ascites
Correct answer: C. Tumour limited to one ovary with capsule ruptured before surgery
Explanation
In the FIGO 2014 classification, Stage IC is subdivided: IC1 = surgical spill (capsule ruptured during surgery); IC2 = pre-operative rupture of the capsule or tumour on the surface of ovary/fallopian tube; IC3 = positive peritoneal cytology or malignant cells in ascites. IC2 specifically captures spontaneous or pre-operative capsule rupture, which carries a worse prognosis than surgical spill alone.
