三阴乳腺癌受体表型转化情况对乳腺癌患者临床预后的影响
目的评价乳腺癌患者雌激素受体(ER)、孕激素受体(PR)和人表皮生长因子受体2(HER-2)的表达及复发前后受体表型的转化情况对解救治疗疗效及临床预后的影响。方法纳入解放军307医院1994年9月-2011年11月收治的乳腺癌患者211例,根据ER、PR和HER-2受体表型转化情况分为3组。A组(n=20):原发肿瘤灶为三阴乳腺癌(ER、PR和HER-2表达均为阴性,TNBC),复发转移后转化为非TNBC;B组(n=73):原发肿瘤灶为非TNBC,复发转移后转化为TNBC;C组(n=118):原发肿瘤及复发转移灶均为TNBC。对患者的一般资料进行总结,分析复发转移情况、解救治疗疗效及临床预后。...

Summary: | 目的评价乳腺癌患者雌激素受体(ER)、孕激素受体(PR)和人表皮生长因子受体2(HER-2)的表达及复发前后受体表型的转化情况对解救治疗疗效及临床预后的影响。方法纳入解放军307医院1994年9月-2011年11月收治的乳腺癌患者211例,根据ER、PR和HER-2受体表型转化情况分为3组。A组(n=20):原发肿瘤灶为三阴乳腺癌(ER、PR和HER-2表达均为阴性,TNBC),复发转移后转化为非TNBC;B组(n=73):原发肿瘤灶为非TNBC,复发转移后转化为TNBC;C组(n=118):原发肿瘤及复发转移灶均为TNBC。对患者的一般资料进行总结,分析复发转移情况、解救治疗疗效及临床预后。结果全组211例患者复发转移时中位年龄52(22~78)岁,以单发转移为主,首发转移最常见的部位依次为淋巴结、骨和皮肤。A、B、C三组患者的中位无病生存期分别为34.0、25.0、20.0个月。B、C组一、二、三线解救治疗的临床有效率显著高于A组(P=0.030、0.003、0.001),但A组在解救内分泌治疗中的临床获益率显著高于B、C组。211例患者的中位随访时间为68(20~127)个月。A、B、C三组复发后中位生存期分别为63.1、33.7、25.8个月(P=0.000),中位总生存期分别为156.7、67.8、47.4个月(P=0.000)。结论乳腺癌患者复发前后ER、PR和HER-2受体表型转化可影响临床预后,在制定解救治疗方案时应对ER、PR和HER-2受体的表达情况进行检测。 |
