Surgical treatment of endometrioid endometrial carcinoma - laparotomy versus laparoscopy

Abstract

Objective: Recent publications have raised doubts about the oncological safety of a laparoscopic approach in the treatment of endometrial cancer. The aim of this study was to investigate the beneficial aspects of laparoscopy versus laparotomy in patients with endometrial cancer, and present oncological outcomes.

Material and methods: A retrospective study of patients who underwent surgery for the treatment of endometrioid endometrial cancer was performed. Surgical outcomes and complications in patients who were treated by laparoscopy or open surgery were compared. The patients were followed for 5-years. Patients’ characteristics, tumor stage, complications rate and oncologic outcome were analyzed.

Results: A total of 151 patients were included. The laparoscopy (n=80) and laparotomy (n=71) groups were homogeneous in regards of demographic data and tumor stage. Median average blood loss (1.31 vs. 1.92 g/dL), the mean duration of hospitalization (5.73 vs. 12.25 days), intraoperative (0 vs. 6%), and severe postoperative complications (5.1 vs. 14.3%) were significantly lower in the laparoscopy group. The numbers of pelvic or para-aortic lymph nodes removed during systematic lymphadenectomy were similar in both groups. Women who underwent laparoscopy and those who underwent laparotomy had similar five-year recurrence-free survival rates (88.7% vs. 91.5%, p=0.864), as well as similar overall five-year survival rates (91.2% vs. 97.2%, p=0.094).

Conclusion: The oncological outcome of laparoscopy was similar to that of laparotomy in the treatment of patients with endometrial cancer. However, surgical outcomes and morbidity rates were significantly better in patients treated by laparoscopy. Clinical trials are essential to evaluate the oncological efficacy of laparoscopy in patients with endometrial cancer.
