Relevance: Researchers interest in the HRAS gene has grown due to the discovery of this genes increased expression in breast cancer. Activated forms of Ras increase in breast cancer cell lines and EGFR or HER2 expression. Consequently, Ras can be activated in breast tumors in the absence of direct mutational activity and reach 20-50% of cases. Inhibiting expression by interrupting signaling pathways from H-Ras to the nucleus may be a promising therapeutic approach. The study aimed to study the clinical and morphological criteria of locally progressive breast cancer and the expression of the HRAS cancer protein in patients receiving various treatment regimens with a farnesyltransferase inhibitor to improve early diagnosis. Materials and Methods: We were adopted between January 2016 and February 2019 by a group of 100 patients diagnosed with local breast cancer. Their age ranged from 29 to 78 years old, and the average age was 59±. Determination of immunohistochemical expression of oncohistochemical preparations of HRAS. Results: In breast cancer patients, there was an association between HRAS expression and Her2/neu expression (P=0.001) and the ki-67 tumor proliferation index (P=0.001). Analysis of the relationship between H-Ras expression showed a relatively strong association with progression-free survival before treatment (V=0.47; p=0.001) and after treatment (V=0.45; p=0.001). Conclusion: These results may indicate the clinical use of HRAS as a prognostic factor or therapeutic target for breast cancer.
