Abstract

Abstract: Surgical treatment of low-grade endometrial stromal sarcoma consists of hysterectomy. The role of oophorectomy is yet to be established. We aimed to examine the effect of preserving the ovaries on the pattern of recurrences in patients with stage I disease. Thirty-four patients with stage I low-grade endometrial stromal sarcoma were retrospectively analysed. Based on ovarian preservation the whole cohort was divided into two groups. Recurrence (liver, lung, groin and bone) was detected in 4 (11.8%) cases. No significant differences in overall survival or disease-free survival (DFS) were observed between the ovarian preservation and bilateral salpingo-oophorectomy (BSO) groups. Subset analysis revealed no significant difference in DFS between the ovarian preservation and BSO groups in the premenopausal arm. And also, the performance of pelvic ( n = 2) or para-aortic lymphadenectomy ( n = 6) or adjuvant hormonal therapy did not alter DFS significantly. The 5-year DFS rate for the group which received adjuvant radiotherapy was 62.5 and 94.4% for those which did not ( p = .014). Preserving the ovaries had no adverse effect on the recurrence of stage I disease. IMPACT STATEMENT: What is already known on this subject? Due to the rarity of the disease and the common postoperative diagnosis, only retrospective studies have been reported on low-grade endometrial stromal sarcoma. This disease is commonly diagnosed in premenopausal patients during the early stage. There is no consensus on preserving the ovaries, particularly in young patients, due to the tumour's hormonal characteristics and the risk of late recurrences. What do the results of this study add? Ovarian preservation had no effect on the recurrence of stage I low-grade endometrial stromal sarcoma. Lymphadenectomy and adjuvant hormonal treatment had no effect on DFS, and adjuvant radiotherapy decreased DFS in the current study. What are the implications of these findings for clinical practice and/or further research? Ovarian preservation should be considered, to prevent the negative effects of surgical menopause, particularly in young patients.
