子宮体癌に対する腹腔鏡下手術のoncologic outcomeに関する後方視的検討

抄録

Objective: Although there are many reports from foreign countries that laparoscopic surgery for endometrial cancer has a similar prognosis to open surgery, there are few reports from Japanese institutions. The aim of this study is to assess the oncologic outcome of laparoscopic surgery for endometrial cancer in a Japanese hospital.

Materials and Methods: Patients who had undergone laparoscopic surgery for endometrial cancer between August 2012 and February 2016 in our hospital were retrospectively investigated with medical records. The patients whose post-operative follow-up period was less than 3 years were excluded. The over-all and disease-free survival rate of the patients were calculated, and the recurrent pattern of recurred patients were analyzed.

Results: Seventy-four cases were included in this study. Their median age was 55 years-old, and median follow-up period was 49 months. Lymphadenectomy was performed in 26 cases (35.1%), and adjuvant chemotherapy was given for 17 cases (23.0%). In the follow-up period, seven cases had recurrence. Lung was the most common site as the first recurrence of the patients. Estimated 5 years over-all and diseases-free survival of the 74 patients were 97.2% and 90.5%, respectively. Our survival rates were not inferior to those of previous reports.

Conclusion: The laparoscopic surgery for endometrial cancer has been performed with good prognosis in our hospital same as that in other institutions. It should be more widely spread for endometrial cancer patients also in Japan.
