A 58-year-old postmenopausal woman presents with postmenopausal bleeding. Transvaginal ultrasound shows endometrial thickness of 12 mm. Endometrial biopsy is performed and reveals endometrioid adenocarcinoma. MRI shows tumor confined to the inner half of the myometrium with no cervical extension. Lymph nodes appear normal. What is the FIGO 2023 stage?
- A Stage IB
- B Stage II
- C Stage IA ✓
- D Stage IIIA
Correct answer: C. Stage IA
Explanation
In FIGO 2023 staging for endometrial carcinoma, Stage IA is defined as tumor limited to the endometrium or invading less than half of the myometrium (inner 50%), with no lymphovascular space invasion (LVSI) and favorable histology. Stage IB involves outer half (≥50%) myometrial invasion. Stage II requires cervical stromal involvement. This patient has inner half invasion, no cervical extension, and no nodal disease, consistent with Stage IA.
