Evaluation of HER2/neu gene amplification (duplications) frequency in patients with breast cancer using MLPA method

Her2/neu is a biomarker which is overexpressed in a subset of breast cancer patients who are eligible to receive treatment. Her-2 gene amplification analyzed by MLPA that is a new method to detect Her-2 status in clinical practice. 60 patients, who were operated in Afzalipour Hospital of Kerman, were enrolled in this cross-sectional study. The pathologic specimens were evaluated by MLPA method for detecting HER2 overexpression. The data were analyzed by SPSS21 software and CHI SQUARE test. Correlation between HER2 overexpression and lymph node involvement was remarkable (P value=0.0). HER2 over overexpression and size of tumor had obvious relation (P value=0.036). All the patients with HER2 overexpression were stage3 of malignancy (P value=0.0). According to the results of this study it can be concluded MLPA method is a suitable method for detecting overexpression of HER2 in patients with breast cancer.
