早期子宮体癌に対する腹腔鏡下手術および開腹手術の予後の検討

Objectives: Laparoscopic hysterectomy is currently performed in a large number of patients. We investigated the recurrence, disease-free survival (DFS), and overall survival rates of laparoscopic vs. abdominal hysterectomy for the treatment of early-stage endometrial cancer.

Methods: The study included 240 patients with stage IA endometrial cancer (endometrial adenocarcinoma, adenosquamous carcinoma, mucinous adenocarcinoma G1/G2) who underwent surgical treatment between 2007 and 2017. Laparoscopy was performed in 97 (laparoscopy group [L group]) and laparotomy in 143 patients (laparotomy group [O group]). We performed an intergroup comparison of recurrence, DFS, and overall survival rates.

Results: No intergroup differences were observed in recurrence (5.2% [L group] vs. 7.3% [O group]), DFS (90.3% [L group] vs. 94.1% [O group]), and overall survival rates (98.8% [L group] vs. 97.3% [O group]).

Conclusions: Long-term prognosis of laparoscopic surgery was not inferior to that of laparotomy for early-stage endometrial cancer.
