title: The utility and management of vaginal cytology after treatment for endometrial cancer.
abstract: OBJECTIVE
  To estimate the accuracy of vaginal cytology in postoperative surveillance for detecting recurrent endometrial cancer and to estimate the optimal management of squamous abnormalities detected in this setting.
  
  
  METHODS
  This review included women who underwent hysterectomy for endometrial cancer between January 1, 2006, and December 31, 2010, and had at least one postoperative Pap test. Clinical and demographic data were collected and outcomes including abnormal vaginal cytology, results of colposcopic examination, and endometrial cancer recurrence were assessed. A Cox regression model to estimate the risk of abnormal cytology was created. Sensitivity, specificity, and negative and positive predictive values of detecting vaginal recurrences were calculated.
  
  
  RESULTS
  Four hundred thirty-three women contributed 2,378 Pap tests. At least one abnormal cytology result was found during follow-up of 55 (13%) women, representing 3% of all Pap tests. No recurrent endometrial cancers were diagnosed on the basis of isolated abnormal cytology. No cases of recurrent cancer were diagnosed in women with atypical squamous cells of undetermined significance or low-grade squamous intraepithelial lesion (LSIL) Pap test results. In multivariable analysis, abnormal cytology was highly associated with prior postoperative radiation therapy (P<.001). The sensitivity, specificity, and positive and negative predictive values of an abnormal Pap test result in detecting a local recurrence are 40%, 87.9%, 7.3%, and 98.4%, respectively.
  
  
  CONCLUSIONS
  Colposcopy is not needed after a Pap test result read as atypical squamous cells of undetermined significance or LSIL.
