Lancet Oncol:“顺铂联姻化疗”可延长复发转移乳腺癌患者生命

2015-04-09 佚名 中国科学报

由复旦大学附属肿瘤医院联合全国12家研究中心完成的一项原创性临床研究——吉西他滨联合顺铂的化疗方案,可显著延长转移性三阴性乳腺癌患者的生存期。相关研究成果日前发表于《柳叶刀—肿瘤学》。 该院胡夕春教授、张剑医生等自2011年起,将240名年龄分布在18岁~70岁、病程处于复发转移阶段且未行化疗的三阴性乳腺癌患者,随机分成“吉西他滨联合顺铂”(以下简称顺铂组)和“吉西他滨联合紫杉醇”(以下简称紫杉

由复旦大学附属肿瘤医院联合全国12家研究中心完成的一项原创性临床研究——吉西他滨联合顺铂的化疗方案,可显著延长转移性三阴性乳腺癌患者的生存期。相关研究成果日前发表于《柳叶刀—肿瘤学》。

该院胡夕春教授、张剑医生等自2011年起,将240名年龄分布在18岁~70岁、病程处于复发转移阶段且未行化疗的三阴性乳腺癌患者,随机分成“吉西他滨联合顺铂”(以下简称顺铂组)和“吉西他滨联合紫杉醇”(以下简称紫杉醇组)两组,进行了为期8个周期的治疗。16.3个月和15.9个月之后的随访结果证明:顺铂组的中位无进展生存期达到7.73个月,较紫杉醇组显著延长了1.3个月。

此次历时4年的临床研究,还有一个被胡夕春称为“具有里程碑意义”的发现是:绝大多数早期三阴性乳腺癌患者,都经过紫杉醇类药物的治疗,一旦发生复发转移,就会陷入“无标准治疗方案”的窘境。目前通常的治疗手段,患者的中位无进展生存期仅为3~4个月;而进入顺铂组进行治疗者,其中位无进展生存期将能再延长3~4个月。两者比较,生存期增加了一倍。

在所有乳腺癌患者中,约有20%的人缺乏ER、PR、HER2等3种常见的存在于乳腺癌细胞的受体。这类“三阴性”乳腺癌患者,因其病理分子分型恶性程度高、易发生远处转移,一直是临床上关注的焦点。此次中国团队终于在世界范围内首次发现了一个不但有效、而且安全性良好的治疗方案。“我们可以负责任地说,为转移性三阴性乳腺癌患者制定含有顺铂药物的化疗方案,可以视为一种当下更加凸显疗效和生存质量的最优选择。”复旦大学附属肿瘤医院乳腺外科主任邵志敏教授表示。
