ABSTRACT
Background: Ovarian cancer is the leading cause of cancer related death amongst women in India. Identification of histological types helps to predict tumor behaviour and further appropriate management. Aims and objectives is to study the histopathological parameters of ovarian tumor.Methods: This retrospective study was done on patients who presented ovarian mass and subsequently underwent surgery in a Regional Cancer Centre, Odisha, over a period of three years from January 2016 to December 2018. All datas such as age, site, gross findings and histological tumor types were retrieved from pathology and analyzed using MS Excel worksheet.Results: A total 612 cases of ovarian tumor were included for study. Non-neoplastic to neoplastic tumor ratio was 1:7.74. Surface epithelial tumors comprised the majority of tumors, accounting for 452 cases (83.39%). Malignant lesions were predominant in this series 416 cases (76%). Majority of borderline tumors were of mucinous subtype 20 (76.92%). The Mean±SD ages of all benign comprising, borderline and malignant tumors were 47.4±11.9, 44.9±14.3 and 46.9±13, respectively. On the basis of two tired grading system, high grade malignant serous tumors were maximum, 226 (74.34%). Ovarian surface involvement, omental invasion, uterine invasion, LVSI, capsular invasion and pelvic lymph node involvement was observed in 146 (35.26%), 106 (25.6%), 12 (2.89%), 70 (16.9%), 6 (1.44%) and 12 (2.89%) respectively. According to the FIGO staging system, among primary malignant tumor, 58% patients were presented in late stage (III and IV).Conclusions: The high incidence of malignant ovarian tumor with late presentation was observed in our study. So, further study is warranted to elucidate the major factors in our population.
