摘要 目的观察右丙亚胺(Dexrazoxane,DEX)对早/中期女性乳腺癌患者术后表阿霉素(EPI)辅助化疗时的心脏保护作用。方法随机将来我院治疗的早/中期女性乳腺癌患者分为观察组和对照组,两组患者均采用EPI为主的术后辅助化疗方案,观察组在EPI为主的化疗方案基础上加用DEX(DEX∶EPI=10∶1),在第1次应用EPI时即给予DEX。采用心肌钙蛋白T(cTnt)和左心室射血分数(LVEF)监测治疗前、治疗第1和第3个周期、治疗完成时、完成后半年、1年和2年的心脏功能状态,同时观察治疗的非心脏毒性。结果两组患者在年龄、体重、ECOG评分和分期方面没有统计学差异(P>0.05)。EPI治疗第1个周期开始cTnt明显上升,到治疗结束时达到最高,直到治疗后2年仍然维持在较高水平;加用DEX组在治疗期间及治疗后cTnt水平都较低;而LVEF在两组的各个治疗阶段水平都没有统计学差异(P>0.05);两组的非心脏副反应没有差异。结论EPI从第1次应用时对心脏就产生了明显的毒性,加用DEX可以降低这种心脏毒性。
