With Cox univariate analysis, only tumour stage (HR=0.158 (CI 95%, 0.039–0.636), P=0.034) and pathological nodal status (HR=7.118 (CI 95%, 1.864–27.177), P=0.004) were significantly associated with OS, whereas the level of HER-2 amplification was not (HR=1.974 (CI 95%, 0.413-9.425), P=0.394). Here, ERBB2 is linked to neoplasm.
