The guidance of intraoperative frozen section for staging surgery in endometrial carcinoma: frozen section in endometrial carcinoma.

Abstract

The objective of this study was to evaluate the reliability of an intraoperative frozen section during the endometrial carcinoma staging surgery procedure. The paraffin section reports of 291 cases with endometrial carcinoma were compared with intraoperative frozen section reports, which were diagnosed in the Pathology Department of Cukurova University, Medical Faculty between June 2006 and December 2012. The reports were reviewed for diagnostic accuracy of the frozen section in terms of histological subtype, grade, and myometrial invasion. Concordance values between frozen and paraffin section reports were 86, 84.3, and 91.6% for histological subtype, grade, and myometrial invasion, respectively. When collectively evaluated, two (0.7%) of 291 patients were inappropriately operated on due to frozen section reports. Intraoperative frozen section is a reliable guide for surgeons to evaluate the risk group of patients with endometrial cancer and prevent an unnecessary staging surgery operation.
