Abstract: Ovarian cancer is the second most common malignancy of the female genital tract and the seventh most common cancer in women. Ovarian cancer is 4% of all women cancers. Total 90% of ovarian cancers are epithelial type. The aim of this study was to evaluate FIGO stage, tumor histology and grade in patients with ovarian cancer. We performed a retrospective chart review of all patients with ovarian carcinoma who received their primary treatment at our institution between 2004 and 2006. A total of 42 patients were identified. Of these, 50% was in stage III, 59.6% had grade 2 and 54.8% had parity 5 and more. The most common histologic type was epithelial (85.7%). Significantly correlation was not found between histology and grade of tumor (p = 0.586) but histology of tumor had significantly correlation with stage of tumor (p = 0.017). Histology of tumor had not significantly correlation with age group of patients (p = 0.111). With increasing of tumor grade the stage of tumor was increased. Significantly correlation was found between ascites and presence of malignant cells in ascitis fluid. With increase of grade and stage of disease, frequency of ascites was high and with increase of patients age, stage of tumor significantly increased. With increase of tumor grade, frequency of omentum involvement and ascites were high. With attentive that in present study on 42 patients, stage and grade of disease were high, establishing the programs for improving of women`s attitude about ovarian cancer are necessary.
