Stage II adenocarcinoma of the endometrium: Adjuvant radiotherapy and recurrence patterns

Purpose: Review patterns of recurrence for Stage II endometrial cancer in a community practice. Methods and Materials: A retrospective review of patients with endometrial cancer diagnosed between 1985-2002. Patients were excluded for Stages I, III , or IV or treatment with preoperative pelvic radiation (external beam radiation therapy [EBRT]). Results: Eighty-six patients with a mean follow-up of 70 months are reported. Higher risk patients were selected for adjuvant radiation with no apparent differences for those receiving only EBRT compared with EBRT with brachytherapy. Five-year actuarial vaginal, pelvic sidewall/nodal, and metastatic control rates were 100% and 100%, 96.9% and 100%, and 79% and 84.2% for patients receiving EBRT or EBRT with brachytherapy. Overall survival rates were 70.5% and 75.8%, and cause-specific survival rates were 78.8% and 82.9% for those receiving EBRT or EBRT with brachytherapy. A select group was observed and experienced one vaginal recurrence with overall and cause-specific survival rates of 100%. Conclusion: In higher risk patients with Stage II, adjuvant EBRT achieves excellent vaginal and pelvic sidewall/nodal control without apparent benefit from additional brachytherapy. Select patients may not require adjuvant treatment. (c) 2008 Elsevier Inc.
