ERBB2 and breast cancer: The 5-year DFS rate was 67% (CI95, 62–73; N = 343) in the CL subtype (Figure 3B), intermediate between that observed in ERBB2-enriched BC patients (55% 5-year DFS, p = 2.3 E-03, log-rank test; N = 426) and luminal A BC patients (79% 5-year DFS, p = 6.7 E-07, log-rank test; N = 982) and normal-like BC patients (79% 5-year DFS, p = 4.7 E-04, log-rank test; N = 299).
