To Determine the Accuracy of Frozen Section in the Management of Ovarian Tumours

BACKGROUND Frozen section done during surgery provides a valuable tool in the diagnosis and classification of tumours into benign, borderline and malignant. In this study, we evaluated the intraoperative findings and the accuracy of the frozen section and compared it with the final histopathology report. METHODS A retrospective study was done in the Department of Obstetrics and Gynecology in Sri Ramachandra University and Research Centre from January 2017 to January 2020, for a period of 3 years and data was taken from the patients who underwent surgery-staging laparotomy for ovarian masses along with frozen section in the diagnosis of their tumor. The final histopathology report is the gold standard for detection of ovarian tumours. The accuracy of the frozen section was compared with the final histopathological report on paraffin section. RESULTS There was a total of 109 cases during the study period of 3 years. Out of the total, frozen section showed 55 malignancy cases, 7 cases were borderline, and 47 cases were benign tumors; whereas the final histopathology report showed 51 malignant cases, 9 borderline cases, and 49 cases were benign tumors. This shows that frozen section has almost 97 % accuracy. CONCLUSIONS Frozen section is a very good tool in the diagnosis of tumour whether benign, borderline or malignant and when compared with the final histopathological report gives good accuracy. The diagnosis given during surgery is helpful in the further management of patients according to the stage of the tumour.
