A 60-year-old postmenopausal woman undergoes surgery for a 10 cm ovarian mass. Histology shows bilateral serous adenocarcinoma confined to both ovaries with capsule intact and no surface involvement, negative washings. According to FIGO 2014 staging, the stage is:
- A Stage IC1
- B Stage IA
- C Stage IB ✓
- D Stage IIA
Correct answer: C. Stage IB
Explanation
FIGO 2014 stage IA is tumour limited to one ovary with capsule intact. Stage IB is tumour limited to both ovaries with intact capsules and no surface involvement, negative washings—exactly this scenario. IC substages require capsule rupture, surface involvement, or positive washings. Stage IIA would require extension to the uterus or fallopian tubes.
