Clinical and pathological features of 123 invasive breast tumor specimens.

P-values listed as NS (not significant) >0.05.aOther included histological types including tubular, medullary, apocrine, and mucinous carcinomas.bIHC markers were used as surrogates to define subtype as follows: luminal A = ER and/or PR+/HER2−; luminal B = ER and/or PR+/HER2+; HER2-enriched = ER and PR−/HER2+ and triple negative = ER, PR and HER2−.

P值标注为NS（无统计学意义，not significant）且P>0.05。
a. 其余纳入的组织学类型包括管状癌、髓样癌、大汗腺癌及黏液腺癌。
b. 免疫组化（Immunohistochemistry，IHC）标志物被用作亚型分类的替代指标，具体如下：管腔A型（luminal A）：雌激素受体（Estrogen Receptor，ER）和/或孕激素受体（Progesterone Receptor，PR）阳性且人表皮生长因子受体2（Human Epidermal Growth Factor Receptor 2，HER2）阴性；管腔B型（luminal B）：ER和/或PR阳性且HER2阳性；HER2富集型（HER2-enriched）：ER与PR阴性且HER2阳性；三阴性亚型（triple negative）：ER、PR及HER2均阴性。
