HISTOPATHOLOGICAL SPECTRUM OF OVARIAN TUMORS : 5 YEARS RETROSPECTIVE STUDY IN A TERTIARY REFERRAL HOSPITAL IN ASSAM

Abstract

Introduction : Ovarian tumor accounts for 30% of female genital tract cancers and comprises of large variety of neoplastic entities. Mortality rate has due to ovarian tumor has gradually increased. The present study was undertaken to study the frequency of various histomorphological spectrum, histological subtypes and age distribution pattern of ovarian tumors. Methods: Retrospective study was carried during period of 1st January 2015 to 31st st December 2019, 455 cases of ovarian neoplastic lesions were taken from the records of the department. Classication was done according to WHO classication. Results: Of the 455 cases, 332 cases (73%) were benign, 16 cases (3.5%) cases were borderline and 107 cases (23.5%) cases were malignant. Among the histological subtypes surface epithelial tumors are common comprised of 76.9% followed by germ cell tumors (19.6%). Serous cystadenoma (42.8%) was the most common benign tumor followed by mature cystic teratoma (16.5%). Among the malignant tumors, the most common was Serous cyst adenocarcinoma (11.9%) Tumors were seen over age range of 11-81 years. Maximum number of cases were in the 4th to 6th decade. Benign tumors were primarily seen in Younger age group , whereas malignant tumors were common in elderly age group. Conclusions: In our study we analysed all the spectrum of ovarian tumors diagnosed on the basis of histomorphology. Surface epithelial tumors were the commonest ovarian tumor. Maximum numbers of ovarian tumors were in the age range 40-59years and malignant tumors were common in age >40 years
