A 65-year-old obese woman undergoes hysterectomy and bilateral salpingo-oophorectomy for endometrial carcinoma. Histology shows endometrioid adenocarcinoma, FIGO grade 2, myometrial invasion of 55% (outer half), no cervical stromal involvement, no lymphovascular space invasion (LVSI). What is the FIGO 2023 stage?
- A FIGO Stage IA
- B FIGO Stage IIA
- C FIGO Stage IB ✓
- D FIGO Stage IIIC1
Correct answer: C. FIGO Stage IB
Explanation
FIGO 2023 endometrial carcinoma staging: Stage IA = endometrioid Grade 1–2 confined to endometrium or <50% myometrial invasion without LVSI. Stage IB = Grade 1–2 with ≥50% myometrial invasion (or Grade 3 confined to endometrium/inner half). This patient has grade 2, ≥50% invasion (55%), no LVSI, no cervical involvement — FIGO Stage IB. Cervical stromal involvement would be Stage IIIA, and lymph node involvement Stage IIIC.
