RETROSPECTIVE STUDY OF OVARIAN TUMORS AND TUMOR LIKE LESIONS

Objective: To find frequency of various Neoplastic and non-neoplastic lesion of the ovaries and to analyzeits clinical presentation.Method: This study was conducted from first July 2007 to 30lh June 2010 in Gynae unit B of DHQ Mardan.All the cases of ovarian Tumours which were initially recruited after ultrasonography and were laterconfirmed by open surgery were included in the study Patients record files were used for collection ofrelevant data including detailed history, examination, investigations and operative findings. All thespecimens were sent for histopathology diagnosis to histopathology section lady reading hospital and a copyof report was attached in patients record files.Result: Out of 7574 Gynanocological admission 191 cases (2.5%) of ovarian Tumours were detected. Nonneo-plastic lesion were more common 98 (51.31%) than neoplastic lesion 93 (48.69%). Among theneoplastic lesion 69.89% were benign while 30% were malignant, serous cystadenoma were the commonestbenign Tumours (35.48%) followed by mucinous cystadenoma (21.50%). Serous cyst adenocarcinoma(10.75%) was the commonest malignant Tumour followed by mucinous cystadenomcarcinoma (8.6%).Average age at presentation was 57 years for malignant ephithelial Tumours, 40 years for gonadal stromalTumours and 22.5 % for germ cell Tumours. There was significant difference in the mean age for benign andmalignant ovarian tumours(34 versus52 p =0.0001)Conclusion:Epithelial ovarian Tumours are the commonest Tumours followed by Germ cell Tumours. Agehas strong correlation with the histological type of the Tumour. Grade, histological type and age of thepatient are important prognostic factors. Ultrasound assessment of risk of malignancy favours better patientmanagement. Menstrual irregularities ,mass and pain abdomen were the commonest clinical presentations.Keywords: Ovarian Tumours, Ovarian neoplasm, Ovarian non-neoplastic lesion.
