Seven-year survival analysis in women with unsuspected uterine malignancy after laparotomic versus laparoscopic hysterectomy: A national claim data retrospective cohort study.

In women with UUM diagnosed after hysterectomy for benign diseases, overall survival up to 7 years favors laparoscopy over laparotomy, especially in UUMOEC and the incidence of UUM is relatively low. However, considering the devastating effect of intraperitoneal dissemination of UUM, surgeons should fully explain this issue to patients preoperatively and try to avoid intraperitoneal spread of tumor cells intraoperatively.
