A 55-year-old postmenopausal woman undergoes total abdominal hysterectomy and bilateral salpingo-oophorectomy for a uterine mass. Histopathology reveals endometrioid adenocarcinoma confined to the inner half of the myometrium with no lymphovascular space invasion and no cervical involvement. According to FIGO 2023 staging, this tumour is classified as:
- A Stage IB
- B Stage II
- C Stage IA ✓
- D Stage IIIA
Correct answer: C. Stage IA
Explanation
FIGO stage IA endometrial carcinoma is defined as tumour confined to the uterus with invasion of less than 50% of the myometrial thickness (inner half). Stage IB involves ≥50% myometrial invasion. Stage II requires cervical stromal invasion. Stage IIIA involves uterine serosa or adnexa. Low-grade (Grade 1 or 2) Stage IA endometrioid carcinoma generally has an excellent prognosis with surgery alone.
