The TTP value was significantly different between luminal A and TNBC, between luminal B and TNBC, and between HER-2-enriched BC and TNBC (all P< 0.05), and those differences were confirmed in the univariate analysis (all P<0.05).The ADC value was significantly different between luminal A and TNBC, between luminal B and HER-2-enriched BC, and between HER-2-enriched BC and TNBC (all P<0.05), and those differences were confirmed in the univariate analysis (all P<0.05). This evidence concerns the gene ERBB2 and breast cancer.
