In multivariate Cox regression analysis the following factors were included in the analysis: patient age, tumour size, tumour stage, tumour grade, NPI, ER, PgR and Her-2 status, LVI, and LN status (all were significant with regard to survival analysis with P values < 0.001 for all markers in terms of BCSS (except for age, P = 0.03), and P < 0.001 for all markers in terms of DFS [except for age and ER status where P values were 0.002 and 0.004, respectively)]. Here, ERBB2 is linked to neoplasm.
