After Bonferroni correction for 2 comparisons, P < 0.025 were considered significant, the mutation rate was significantly higher in the IHC-positive group than in the IHC-negative group (p = 0.008), the FISH-positive rate was higher in the IHC-positive group than in the IHC-negative group (approached significance, p = 0.027) (Table 3 ).
