OBJECTIVES: Our objective is to investigate the prevalence, pathology and prognosis of uterine sarcomas in laparoscopic hysterectomy/myomectomy with electric power morcellation for presumed leiomyomas.
STUDY DESIGN: We retrospectively reviewed patients with laparoscopic power morcellation (LPM) for presumed leiomyomas in a Chinese tertiary institution by chart review from September 1, 2013 to December 31, 2016.
RESULTS: Twenty-four in 4478 patients (0.54%) with LPM for presumed leiomyomas had unexpected cancers. The patients showed the highest frequency of occult cancers (10/375, 2.6%) at 51-60 years and lowest (0/255) before 30 years. The pathology included 14 endometrial stromal sarcomas (ESS) (low-grade 12 and high-grade 2), 9 leiomyosarcomas, and 1 malignant mixed mesodermal tumor. The patients underwent abdominal re-exploration including total hysterectomy with bilateral salpingo-oophorectomy and staging surgery. Three patients were at advanced FIGO stage (IIIb-IVb) and 21 at stage I. Seven patients recurred within 1-25 (mean 6.29) months including 5 leiomyosarcomas, 1 high-grade and 1 low-grade ESS. Four recurrent patients with leiomyosarcomas and one with high-grade ESS died of disease in 1-3 months. Seventeen patients had no relapse and were alive for 6-41 (mean 24) months.
CONCLUSIONS: Our study suggests that patients with LPM for presumed leiomyomas appear to have a considerable risk of unexpected cancers. Moreover, morcellation is potentially associated with adverse prognosis in patients with high-grade sarcomas. Informed consent on unexpected cancers that should be discussed before morcellation.
