Multicenter StudyIs there a role for a brachytherapy vaginal cuff boost in the adjuvant management of patients with uterine-confined endometrial cancer?
Many patients who have uterine-confined endometrial cancer with prognostic factors predictive of recurrence are treated with adjuvant pelvic radiation. The addition of a brachytherapy vaginal cuff boost is controversial. ⋯ There is no suggestion that the addition of a vaginal cuff brachytherapy boost to pelvic radiation is beneficial for pelvic control or disease-free survival for patients with Stage I or II endometrial cancer. Prospective randomized trials designed to study external irradiation alone versus external beam treatment plus vaginal brachytherapy are unlikely to show a positive result. Because EBRT provides excellent pelvic control, protocol development for uterine-confined corpus cancer should focus on identifying patients at risk for recurrence as well as other means of augmenting EBRT (e.g. addition of chemotherapy) in order to improve disease free survival in those subgroups.
