title: Risk factors for early and late postoperative complications of patients with endometrial cancer.
abstract: OBJECTIVE
  We have routinely performed staging with pelvic and/or paraaortic lymphadenectomy in patients with endometrial cancer having moderate to high risk for lymph node metastasis. The aim of this study was to investigate the risk factors for the occurrence of early and late postoperative complications in patients managed primarily by surgery in our institution.
  
  
  METHODS
  Two-hundred and fifty-nine consecutive cases of endometrial cancer were enrolled in the study. Past history, body mass index, type of surgery, intraoperative findings, and follow-up information were collected from patient charts. Of these, 200, 127, and 30 patients underwent systematic pelvic lymphadenectomy, systematic paraaortic lymphadenectomy, and radical hysterectomy, respectively. The median numbers of dissected pelvic and paraaortic lymph nodes were 32 and 14, respectively.
  
  
  RESULTS
  None of the complications resulted in death. Of the study population, 36 early complications and 34 late complications occurred. Overall 65 patients (25.1%) had at least one complication. Multivariate analysis revealed that a longer operative time and paraaortic lymphadenectomy were independent predictors for the occurrence of early and late postoperative complications, respectively.
  
  
  CONCLUSIONS
  Since the therapeutic value of lymphadenectomy is still under evaluation, the indications for systematic pelvic and paraaortic lymphadenectomy should be carefully considered.
