According to the revised FIGO 2023 endometrial cancer staging, a patient with endometrioid endometrial carcinoma invading <50% myometrium, no cervical glandular involvement, and a positive pelvic lymph node 0.4 cm is staged as:
- A Stage IA
- B Stage IIIC1 ✓
- C Stage IB
- D Stage II
Correct answer: B. Stage IIIC1
Explanation
Under FIGO 2023 endometrial cancer staging, any regional lymph node involvement (pelvic) regardless of the primary tumour stage upgrades disease to Stage IIIC. IIIC1 = pelvic lymph node involvement; IIIC2 = para-aortic lymph node involvement. The primary tumour (superficial invasion <50% = Stage IA by myometrial extent) is overshadowed by the positive pelvic node. This follows the same principle as the 2018 cervical cancer revision.
