Regarding the FIGO 2014 staging of ovarian cancer, which of the following correctly distinguishes Stage IC1 from IC2?
- A IC1: surgical spill; IC2: capsule ruptured before surgery or on surface ✓
- B IC1: capsule ruptured before surgery; IC2: intraoperative surgical spill
- C IC1: positive washings; IC2: surgical spill
- D IC1: capsule ruptured before surgery; IC2: positive peritoneal washings
Correct answer: A. IC1: surgical spill; IC2: capsule ruptured before surgery or on surface
Explanation
FIGO 2014 Stage IC is subdivided: IC1 = surgical spill (iatrogenic rupture during surgery); IC2 = capsule ruptured before surgery OR tumour on ovarian/tubal surface; IC3 = positive peritoneal cytology/washings. This distinction matters prognostically because IC1 (surgical spill) has a better prognosis than IC2 (pre-operative rupture), though both upstage from IA/IB. The previous single category IC lacked this prognostic granularity.
