2011年St.Gallen共识提出,用雌激素受体 (ER)、孕激素受体(PR)、人表皮生长因子受体2 (HER2)和细胞增殖标志Ki-67这4种分子将乳腺 癌分为++

A(20例,71.4%)或三阴型(16例,69.6%)的趋势,但差异无统计学意义(P=0.009>0.008,
P=0.019>0.008),HER2型组织学Ⅲ级的比例(8例,53.3%)有大于Luminal A型(23例,82.1%) 的趋势,差异无统计学意义(P=0.039>0.008)。三阴型的无淋巴结转移的比例(7例,30.4%)有小 于HER2型(7例,46.7%)或Luminal B型(17例,47.2%)的趋势,差异无统计学意义(P=0.019> 0.008,P=0.016>0.008)。不同亚型患者的发病年龄、是否绝经、手术方式、肿瘤家族史、复发转移危 险度之间差异均无统计学意义(P>0.05)。Luminal A型第3年总生存率为100%,第1、2、3年无事 件生存率均为92.9%,Luminal B型总生存率为100%,第1、2、3年无事件生存率均为97.2%,HER2 型总生存率为100%,第1、2、3年无事件生存率分别为100%、100%、93.3%,三阴型第1、2、3年总生 存率分别为100%、95.7%、95.7%,第1、2、3年无事件生存率分别为95.7%、91.3%、90.O%。是否三 阴型、复发转移危险度、年龄、是否绝经、肿瘤大小、组织学分级、淋巴结转移数目的各组之间3年无事 件生存率差异均无统计学意义(P>0.05)。结论乳腺癌中以Luminal型最多,预后较好。HER2型 的肿瘤>2 cm和组织学分级Ⅲ级的比例较大,3年无事件生存率较低;三阴型易淋巴结转移,3年无 事件生存率最低。肿瘤大小、组织学分级及淋巴结是否转移可能是影响乳腺癌预后的重要因素。
