培美曲塞联合顺铂治疗晚期乳腺癌的疗效观察

目的：观察培美曲塞联合顺铂治疗晚期乳腺癌的临床疗效和不良反应。方法：培美曲塞500 mg/m2,第1天;顺铂75 mg/m2,第1天,21 d为1个周期。所有病例均接受至少2个周期的化疗。结果：30例患者入组均可评价疗效,CR为0,PR为20.0%（6/30）,SD为46.7%（14/30）,PD为33.3%（10/30）,有效率为20.0%（6/30）,临床获益率为46.7%（14/30）。中位随访期10个月,中位TTP 7个月,中位OS 8.5个月,1年生存率为63.3%。主要不良反应为骨髓毒性,有6例（20.0%,6/30）发生了Ⅲ～Ⅳ度白细胞减少;有4例（13.3%,4/30）发生了Ⅲ度血小板减少。结论：培美曲塞联合顺铂方案治疗蒽环类和紫杉类化疗失败的转移性乳腺癌有较好的疗效,患者耐受性好,值得临床进一步研究。
