摘要
目的研究浸润性导管癌中三阴乳腺癌的临床病理特征及其预后。方法回顾性分析我院既有临床资料又有随访结果和蜡块的226例病例,对这226例石蜡标本切片行雌激素受体(ER)、孕激素受体(PR)、人类表皮生长因子受体(HER2)3种抗体的免疫组化染色,并通过电话或信件问卷随访。结果利用ER、PR、HER2 3种抗体的免疫组化结果,可将浸润性导管癌分为luminal A、luminal B、HER2过度表达、三阴和未分型5种类型。其中三阴乳腺癌46例(21.4%),组织学分级以Ⅲ级为多。三阴乳腺癌的肺、胸膜转移率高于luminal A型、luminal B型、HER2过度表达型和未分型(P均<0.05);腋窝淋巴结,锁骨上、下淋巴结转移率低于luminal A、luminal B和HER2过度表达型(P均<0.05)。三阴乳腺癌的疾病缓解率低于ER、PR均阳性的lu-minal A型(P<0.05),生存率低于ER、PR均阳性的luminalA型(P<0.05)和luminal B型(P<0.05)。结论三阴乳腺癌有其不同于其它类型乳腺癌的临床病理特征及转移途径,其预后明显低于ER、PR均阳性的乳腺癌。
Objective To explore the clinicopathological features and the clinical outcome of triple negative breast cancer. Methods A retrospective analysis was performed for 226 women diagnosed and treated for breast cancer in our hospital from 2001 to 2005 with all their clinicopathological features, blocks and follow-up data available. 226 slides were immunohistochemical stained by ER, PR, HER2 three antibodies. Results Invasive ductal breast cancer could be divided into 5 phenotypes (luminal A, luminal B, HER2 overexpression, triple-negative, and null) by using immunohistoehemieal staining with ER, PR, HER2 three antibodies. Triple-negative breast cancer account for 46 cases (21.4%), its histological grade was prone to be grade Ⅲ. The rate of lung and pleural metastases in the triple-negative group was higher than that in luminal A, luminal B, HER2 overexpression and null groups (P 〈 0.05) ; The rates of axillary, supraclavicular and infraelavicular lymph nodes metastases in the triple-negative group were lower than that in luminal A, luminal B and HER2 overexpression groups. Triple-negative tumours were associated with shorter disease free-interval(DFI) than luminal A phenotype(both ER + and PR + )(P 〈0. 05), were associated with shorter overall survival(OS) than both luminal A phenotype( ER + and PR + ) (P 〈0. 05) and luminal B phenotypes ( ER + and PR + ) (P 〈 0. 05 ). Conclusion Triple negative breast cancer is an unique phenotype with its own clinicopathological features and metastases, the clinical outcome is much poorer than the other phenotypes with both ER, PR receptor positive.
