Compatibility of intraoperative frozen sections for ovarian masses in less than 35 years of age with final histopathological examination

Abstract

Thirty percentage of all cancers of female genital tract are ovarian cancer. Ovarian neoplasms are a heterogeneous group of tumours including sex cord stromal tumours, surface epithelial tumours, germ cell tumours, and secondary malignancies. The accuracy of intraoperative frozen section diagnosis of benign and malignant ovarian tumours is very good. This study is designed to assess compatibility of intraoperative frozen sections for ovarian masses in less than 35 years of age with final histopathological examination. A descriptive, prospective, observational study was conducted in Onco – gynaecology department, tertiary care teaching hospital. The study was conducted between July 2015 to May 2017. All the patients under 35 years of age who had ovarian masses and performed intraoperative frozen section were included during the study period. Unmatched frozen section and histopathological findings were seen in two cases. Accuracy of frozen section in diagnosis of benign tumour was 95.65%, borderline tumour was 100% and for malignant tumour was 95.65%. The accuracy of intraoperative frozen section is high, so it is reliable diagnostic tool to assess ovarian mass intraoperatively. It is very important to determine the type and extent of surgery particularly in young women when fertility is concern.
