Abstract

Purpose: This study aims to evaluate the number of cases of occult uterine malignancies in all LASH surgeries at the MIC clinic (Berlin) and to verify how the operative technique affects the prognosis of the disease.

Methods: Data of 10,731 patients who underwent a standardized LASH surgery with electric power morcellation between 1998 and April 30, 2014 were retrospectively analyzed. Main indication for LASH was symptomatic uterine myomas (81.3 %).

Results: No intra-operative complication was caused by use of a morcellator. In total, six sarcomas (0.06 %), including four endometrial stromal sarcomas (0.04 %) two leiomyosarcomas (0.02 %), and eight endometrial cancers (0.07 %) were documented. This amounts to a very low uterine malignancy rate of 0.13 %. Median follow-up period for all six patients with sarcoma and seven patients with endometrial cancer was 65.58 months (13-169). No recurrence was reported for the patients with endometrial cancer and five sarcoma patients in the comprehensible follow-up period. One patient died 13 months after LASH surgery due to the diagnosed leiomyosarcoma with peritoneal carcinomatosis and bone metastases.

Conclusion: In 10,731 morcellated uteri during LASH only 0.06 % sarcoma and 0.07 % endometrial carcinoma were detected. All patients should be informed about the rare possibility of a malignant disease during pre-operative counseling. With a timely follow-up surgery according to the oncologic guidelines, our data suggest a very good prognosis in terms of survival after LASH with morcellation of malignant tumors in the uterus.
