Uterine preservation in low-grade endometrial stromal sarcoma

Abstract

Data on uterine preservation in the management of low grade endometrial stromal sarcoma (LGESS) is scarce due to rarity of this tumor type. Standard management of LGESS involves extrafascial hysterectomy with bilateral salpingo-oophorectomy with debulking of any extrauterine metastatic disease. High estrogen and progesterone receptor expression facilitates adjuvant hormone therapy post-surgery. LGESS frequently affects young women, thus fertility preservation is an important issue in management. Here we describe uterine preservation in two young women diagnosed with LGESS followed by GnRH analogue therapy with favorable outcome. The first case was diagnosed with recurrent endometrial polyp invading myometrium requiring wedge resection of uterus with free margins. Second case presented with a vaginal mass arising from cervix and excision was done through vaginal route. Both patients were prescribed GnRH analogue therapy for six months post-surgery and are currently on follow-up. These case reports add to literature on feasibility of uterine preservation in the management of LGESS.
