title: Early-stage endometrial cancer: is intravaginal radiation therapy alone sufficient therapy?
abstract: For half a century, adjuvant radiation therapy has been an important component in the treatment of patients with early-stage endometrial cancer believed to be at significant risk of local or regional recurrence. The widespread adoption of up-front surgical treatment and staging, including nodal assessment, has raised new questions about the need for and extent of postoperative adjuvant treatment. Furthermore, in some institutions, even in the absence of complete surgical staging, the extent of postoperative adjuvant treatment is being reassessed. These developments have increased interest in the use of intravaginal brachytherapy (IVRT) alone in selected patients whose major risk of recurrence is at the vaginal cuff. The potential advantages of this approach include lower cost and decreased acute and late toxicity. The use of IVRT alone in select patients was examined through a review of the available literature. The authors conclude that there is a subset of patients in whom adjuvant treatment with IVRT alone is adequate. A clinical approach involving patient selection criteria is proposed which suggests separate selection criteria based on whether or not complete surgical staging information is available.
