Comparative Evaluation of Preoperative Imaging and Postoperative Histopathology in 108 Patients Who Underwent Laparoscopic- or Robot-Assisted Surgery for Endometrial Cancer

OBJECTIVES: The aim of this study was to compare preoperative imaging evaluation results and postoperative histopathology examinations of patients who underwent laparoscopic- or robot-assisted surgery for suspected Stage IA endometrial carcinoma. MATERIALS AND METHODS: There were 298 patients diagnosed with endometrial cancer at our institution between April 2014 and March 2019. Preoperative imaging evaluation based on magnetic resonance imaging (MRI) and computed tomography (CT) revealed 180 patients suspected of having Stage IA disease. Of these, 72 underwent open surgery, 12 underwent robot-assisted surgery, and 96 underwent laparoscopic surgery. In this study, preoperative imaging evaluation results and postoperative histopathology examinations of 108 patients who underwent laparoscopic- or robot-assisted surgery were retrospectively compared. RESULTS: Of the 108 patients, who underwent laparoscopic- or robot-assisted surgery for suspected Stage IA disease, 98 had Stage IA, two had Stage IB, and four had Stages II and III disease. The sensitivity of imaging evaluations based on preoperative MRI and CT was 90.7%. CONCLUSION: Utilizing preoperative MRI and CT imaging resulted in a high rate of successful diagnosis of Stage IA endometrial carcinoma.
