Analysis of survival after laparoscopy in women with endometrial carcinoma

BACKGROUND. The effect of the laparoscopic surgical approach on the survival of women with endometrial carcinoma remains unclear. The objectives of the current study were to assess the effect of laparoscopic surgery on the survival of women with early-stage endometrial carcinoma and to analyze the factors that affect such survival. METHODS. A retrospective review of women presenting with clinical stage I endometrial carcinoma (according to the 1988 International Federation of Gynecology and Obstetrics Staging System) was performed. Women treated with laparoscopy were compared with those treated with laparotomy with regard to their characteristics, surgical procedure, treatment, surgical stage, histology, tumor grade, and recurrence-free and overall survival. Factors affecting survival (surgical approach, histology, grade, and surgical stage) were evaluated using multivariate analysis and survival curves were constructed using Kaplan-Meier analyses. RESULTS. One hundred women underwent laparoscopy and 86 underwent laparotomy. Both groups were similar with regard to age, parity, menopausal status, lymphadenectomy, surgical stage, tumor grade, histology, and postoperative radiation therapy. Women who underwent laparoscopy and those who underwent laparotomy had similar 2-year and 5-year estimated recurrence-free survival rates (93% vs. 94% and 90% vs. 92%, respectively), as well as similar 2-year and 5-year overall survival rates (98% vs. 96% and 92% vs. 92% respectively). There was no apparent difference with regard to the sites of recurrence between both groups. In univariate and multivariate analyses, surgical stage, tumor grade, and histology (but not the surgical approach) were found to have a significant effect on survival. CONCLUSIONS. Although longer follow-up is needed, the survival of women with early-stage endometrial carcinoma does not appear to be worsened by laparoscopy. Surgical stage, tumor histology, and tumor grade were found to significantly affect survival regardless of the surgical approach used.
