  • OBJECTIVE: Professional societies have recently urged gynaecologists to counsel patients about the risks of encountering uterine sarcoma at fibroid surgery especially when morcellation is used. Our objective was to learn the preoperative and postoperative characteristics of patients with uterine sarcoma to better counsel patients undergoing surgery for presumably benign fibroids. METHODS: This is a multicentre, retrospective cohort study. Three academic tertiary cancer centres in Southern Ontario over a 13-year period (2001-2014). Patients diagnosed with leiomyosarcoma or endometrial stromal sarcoma were included after identification using pathology databases. A retrospective chart review was conducted to determine clinical characteristics and survival data. RESULTS: The study included 302 patients with uterine sarcomas (221¬†leiomyosarcomas, 81 endometrial stromal sarcomas). Mean age at diagnosis was 55 years, and 59% were postmenopausal. Sarcoma diagnosis was made following endometrial sampling (25%), hysterectomy (69% laparotomy, 2.7% laparoscopic/vaginal), and myomectomy (3.3%). Of all the patients who underwent endometrial sampling, 65% were diagnosed with a uterine sarcoma in this manner. A general gynaecologist performed the primary surgical procedure in 166 of 302 patients (55%). Tumour disruption at the time of primary surgery occurred in 57 of 295 patients (19%): subtotal hysterectomy (21), myomectomy (10), dissection of adherent tumour (17), and morcellation (9). Morcellation, to facilitate a minimally invasive approach, was performed with scalpel (2 at laparotomy, 5 vaginally) and with a laparoscopic electro-mechanical morcellator (2). At a median follow-up of 2.9 years, there was no significant difference in survival for stage I and II patients with tumour disruption (n = 32) compared with those without tumour disruption (n = 143), regardless of sarcoma type (P = 0.6). CONCLUSION: The majority of patients with uterine sarcomas were postmenopausal. Many can be diagnosed preoperatively with endometrial sampling. Forty-one percent of patients with uterine sarcomas had a high preoperative index of suspicion, resulting in intervention by an oncologist. Morcellation with laparoscopic electro-mechanical morcellator was rare.
