摘要 目的探讨老年女性乳腺癌的临床病理特点及分子分型,为老年女性乳腺癌的治疗及判断预后提供依据。方法对60例病理确诊的老年女性(≥60岁)乳腺癌及55例年轻女性(≤40岁)乳腺癌的临床病理资料进行回顾性比较分析,并以免疫组化为基础,将乳腺癌分为4种分子分型:luminal A型l、uminal B型、HER-2过表达型、basal-like型,分析其分布情况。结果老年组病理组织学类型、淋巴结转移率与年轻组无统计学差异(P>0.05),老年组患者肿瘤大小、组织学分级均低于年轻组(P<0.05)。两组分子分型分布比例不同,老年组以luminal A型为主,占67.85%;luminal B型为17.86%,Basl-like型和HER-2过表达型分别为7.14%、7.14%;年轻组分别为35.29%,17.65%,23.91%,17.39%。结论老年女性乳腺癌较年轻女性乳腺癌侵袭性弱、恶性程度低;分子分型以预后较好的luminal A型为主。
