Fertility sparing surgery for ovarian sex cord stromal tumors: a nine case series

Ovarian Sex Cord Stromal Tumors (SCST) are a rare disease carrying a good prognosis. They generally affect young women; therefore fertility preservation is a critical issue. Fertility Sparing Surgery (FSS) showed promising results in both oncologic safety and fertility preservation. A retrospective case series involving 9 patients diagnosed with SCST and treated with fertility sparing surgery at our institution was conducted between January 2000 and May 2015. The median age was 24 years old (10 to 39). The main clinical manifestation was pelvic pain seen in seven patients. Five patients complained about menstrual cycle disorders. The nine patients went through fertility sparing surgery; seven had conservative staging and the other two had a unilateral salpingo-oophorectomy. Three patients out of nine had a pelvic unilateral lymphadenectomy. Two patients received adjuvant chemotherapy. Only two patients presented locoregional recurrence that occurred respectively after 7 and 192 months. The treatment combined chemotherapy and surgery based on mass resection. One patient achieved a natural pregnancy after the treatment. FSS seems to be a suitable approach for SCST. However, more case series and meta-analysis should be conducted.
