Hypermethylation of BRCA1 was demonstrated to be considerably more frequent in individuals with lymph node metastasis (P=0.025). Hypermethylation of P16 INK4A was considerably associated with age (P= 0.015), menopausal status (P= 0.003) and P53 expression (P= 0.011). Hypermethylation of PTEN was considerably connected with menopausal status (P=0.027).RAR 2 hypermethylation was considerably more prevalent in ER-negative (P= 0.002), PR-negative (P0.001) and P53-positive tumors (P=0.020). Association bet ween gene methylation and protein expression. Immunohistochemical analysis was performed to assess the expression of BRCA1 and GSTP1. With all the raise of methylation frequency, protein expression decreased significantly (P0.05; Table VII). Immunohistochemical staining benefits together together with the promoter methylation status of BRCA1 and GSTP1 are shown in Fig. 3.Table VI.
