RESUMO
OBJECTIVES: The present study aimed to investigate the impact of BRCA1 protein expression on the patients' outcome of ovarian serous carcinoma, and its correlation with different clinicopathologic features. METHODS: Immunohistochemistry with BRCA1 was done for 80 cases of ovarian serous carcinoma that had a positive family history. Correlation with clinico-pathologic variables and patients' outcomes was investigated. RESULTS: BRCA1 expression was detected in 61.2% of the studied cases. A significant relation with patients' age, tumor grade and tumor stage was found (P<0.05). Also, there was a significant decrease in disease free survival (DFS) & overall survival (OS) in the positive BRCA1 group. Metastasis, recurrence, residual disease, and mortality rate showed significantly higher figures in patient with BRCA1 expression (P<0.05). CONCLUSION: Positive BRCA1 expression had proven to be associated with advanced stage & grade of tumors, as well as worsened prognostic survival parameters (metastasis, recurrence, residual disease, and mortality) in patients with ovarian serous carcinoma.
