Low-grade endometrial stromal sarcoma (EES) is a rare tumour with a high recurrence rate but a very good prognosis. Responses to hormonal treatment of these recurrences have been published in case reports. The aim of this study was to determine the objective response rate and response duration of hormonal treatment for recurrent or residual low-grade ESS in a consecutive series of patients.Thirteen consecutive patients with residual or recurrent disease were retrieved from the files. Eleven patients with measurable disease were treated with hormones and form the basis of this study. The following data were collected: age, date of primary diagnosis, type of primary treatment, the presence and localization of residual or recurrent disease, type of treatment, response, duration of response and survival.After hormonal treatment 9 (82%) patients showed an objective response (4 complete response; 5 partial response), one showed stable disease (26+ months) and one progressive disease. Response duration was from 4+ to 252+ months (median 48+ months).Hormonal treatment for measurable residual or recurrent low-grade ESS has a high response rate and should be considered as the treatment of choice for patients in which recurrent disease cannot easily be resected.
