Explanation

Post-operative radiotherapy for endometrial cancer is indicated for high-risk features: deep myometrial invasion (>50%), pelvic lymph node involvement, and poor tumor differentiation (grade 3). Enlarged uterine cavity alone is a structural finding, not a risk factor for recurrence, so it is not an indication for radiotherapy.
