Trends in the utilization of adjuvant vaginal brachytherapy in women with early-stage endometrial carcinoma: Results of an updated period analysis of SEER data.

Abstract：

PURPOSE:Adjuvant vaginal brachytherapy (VB) is a well-established and effective radiation treatment modality in women with early-stage endometrial carcinoma. We sought to evaluate and update published trends in the utilization of VB vs. other radiation therapy modalities (pelvic external beam radiation therapy (EBRT) or the combination of VB and pelvic EBRT using the National Cancer Institute's Surveillance, Epidemiology, and End Results database. METHODS AND MATERIALS:The Surveillance, Epidemiology, and End Results database was queried for adult females with histologically confirmed International Federation of Gynecology and Obstetrics 1988 Stage I-II endometrial carcinoma diagnosed from 1995 to 2012 and treated definitively with hysterectomy and adjuvant radiation therapy. Chi-square tests were used to assess differences by radiation type (VB, EBRT, and VB + EBRT) and various demographic and clinical variables. RESULTS:We identified 15,201 patients that met inclusion criteria. There was a significant overall increase in the use of VB was observed from 17.1% in 1995-2000 compared to 57.1% in 2007-2012 (p < 0.0001). Similarly, there was a proportional decrease in the use of EBRT from 54.0% to 25.5% (p < 0.0001) as well as in the use of VB + EBRT from 28.9% to 17.4% during the same period (p < 0.0001). The observed increase in utilization of VB was not limited to any variables (age, race, histological type, International Federation of Gynecology and Obstetrics stage, and the status of lymph node dissection [yes or no]) or the number of dissected lymph nodes. CONCLUSIONS:In this large national database set, there continues to be an increasing trend for the use of VB in the adjuvant setting in women with early-stage endometrial carcinoma.
