Vaginal hysterectomy versus abdominal hysterectomy for the treatment of stage I endometrial adenocarcinoma.
OBJECTIVE: The aims of the current study were to (1) determine the effectiveness of vaginal hysterectomy for the treatment of stage I endometrial cancer and (2) analyze which clinical pathologic parameters were independent predictors of clinical outcome.
STUDY DESIGN: In a retrospective analysis, 5- and 10-year results of vaginal hysterectomy were compared with those of abdominal hysterectomy in 327 cases of stage I adenocarcinoma. No preoperative irradiation was given. Overall, 180 patients underwent vaginal hysterectomy, whereas 147 patients had abdominal hysterectomy (106 cases with lymphadenectomy). The log-rank test was used for evaluation of survival differences.
RESULTS: The 5- and 10-year survival rates (Kaplan-Meier method) were, respectively, 90% and 87% in the vaginal hysterectomy group and 91% and 90% in the abdominal hysterectomy group (difference not significant). The grade of differentiation, depth of myometrial invasion, and age were significantly correlated with survival, whereas histologic type, mode of surgery, lymphadenectomy, and adjuvant radiotherapy were not. In a multivariate analysis (Cox proportional hazards), grade of differentiation and age were independent predictors of clinical outcome, whereas depth of myometrial invasion lost significance.
CONCLUSIONS: Vaginal hysterectomy showed a high rate of cure in stage I endometrial cancer. Therefore it can be used as an alternative to the abdominal operation in obese and poor surgical risk patients and, possibly, in selected low-risk cases.
