When examined at different cut off values, only EGFR staining at >50% of tumour cells (HR = 3.57, CI = 1.07–11.85, p = 0.038) was associated with a poorer overall survival in univariate analysis and EGFR expression at >5% of tumour cells (HR = 2.83, p = 0.019) and its co-expression with HER-2 (HR = 2.83, p = 0.019), HER-3 (HR = 2.48, p = 0.023), and HER-2/HER-3 (HR = 2.60, p = 0.016), were all associated with poorer disease-free survival (Table 4, Figure 2). The gene discussed is ERBB3; the disease is neoplasm.
