A 60-year-old postmenopausal woman with postmenopausal bleeding has endometrial biopsy showing grade 1 endometrioid adenocarcinoma. Imaging shows no myometrial invasion and no lymph node involvement. This is FIGO stage:

• A Stage IB
• B Stage IC
• C Stage II
• D Stage IA ✓

Explanation

FIGO 2023 staging for endometrial carcinoma: Stage IA = tumor limited to the endometrium or invading less than half the myometrium (IA1: no myometrial invasion; IA2: invasion <50% myometrium for low-grade tumors OR nonaggressive histotype). Complete absence of myometrial invasion places this low-grade endometrioid tumor in Stage IA. Stage IB is myometrial invasion ≥50%. Stage II involves cervical stromal invasion. The updated FIGO 2023 classification also incorporates molecular classification.
