Objectives. The aim of this study was to determine the attitudes of the members of the Society of Gynecologic Oncologists with respect to the use of adjuvant radiation therapy in women with endometrial cancer. Methods. An anonymous survey concerning the use of adjuvant radiation therapy in endometrial cancer was mailed to all members of the Society of Gynecologic Oncologists listed in the 1998 directory. Results. Of the 767 listed members, 325 (42%) returned completed surveys. Less than 20% of respondents recommended adjuvant radiation therapy in stage IA grade 1 or 2 and stage IB grade 1 endometrial cancer. Adjuvant radiation is recommended by 40 to 50% of respondents in women with stage IA grade 3 and IB grade 2 tumors. Most recommend adjuvant radiation for all women with >50% myometrial invasion or grade 3 tumors with any myometrial invasion. Lymph node sampling is attempted in all cases by 48% of respondents. For those familiar with Gynecologic Oncology Group (GOG) Study No. 99, 20% stated that they were more likely to recommend adjuvant radiation and 27% stated that they were less likely to recommend adjuvant radiation based on the preliminary results. Except in stage IA grade 1 tumors, the chance of recommending further therapy in women with all stages and grades was significantly less if a complete staging procedure including lymph node dissection had been performed. Conclusions. Complete staging appears to decrease the chance that postoperative therapy will be recommended. The use of adjuvant radiation therapy seem to have declined slightly as a result of GOG Study No. 99. Future studies in women with endometrial cancer that do not require lymph node sampling should evaluate the frequency of adjuvant therapy in the absence of complete staging.
