ERBB2 and neoplasm: The significant factors associated with OS or RFS in univariate analysis were age (OS, p < 0.001; RFS, p = 0.032), tumor stage (OS, p = 0.021; RFS, p = 0.097), T category of stage (OS, p = 0.038; RFS, p = 0.197), lymph node metastasis (OS, p = 0.049; RFS, p = 0.159), histologic grade (OS, p = 0.008; RFS, p = 0.151), mitotic count (OS, p = 0.014; RFS, p = 0.270), and the expression of HER2 (OS, p = 0.009; RFS, p = 0.025), PR (OS, p = 0.093; RFS, p = 0.005), FAM83H-Nu (OS, p < 0.001; RFS, p < 0.001), FAM83H-Cy (OS, p < 0.001; RFS, p < 0.001), and PD1 (OS, p < 0.001; RFS, p < 0.001) (Table 1).
