吉非替尼与多西他赛单药治疗老年晚期肺腺癌的疗效及对心肌损伤的初步分析

目的 回顾性分析吉非替尼和多西他赛单药治疗老年晚期非小细胞肺癌的临床疗效及治疗过程中对患者心肌酶肌酸激酶同工酶(CK-MB)和射血分数的影响;比较两组对患者心肌损伤的差异.方法 2008年1月至2009年12月就诊我院的老年(年龄＞65岁)确诊晚期肺腺癌患者32例.多西他赛组(n=18):多西他赛65 mg/m2,第1天,21天1个周期,连续3个周期;吉非替尼组(n=14):吉非替尼250 mg/d,早餐后2小时口服,连续服用3个月.记录患者临床疗效、心肌酶CK-MB和射血分数变化.结果 吉非替尼组:完全缓解(CR)1例,部分缓解(PR)3例,稳定(SD)3例,疾病进展(PD)7例;多西他赛组:完全缓解(CR)0例,部分缓解(PR)4例,稳定(SD)6例,疾病进展(PD)8例,吉非替尼组与多西他赛组临床有效率分别为28.6%和22.2%,两组比较差异无统计学意义(P＞0.05);吉非替尼组治疗前后心肌酶肌酸激酶CK-MB均值(17.72±9.12)U/L vs(24.03±7.01) U/L,治疗前后比较差异有统计学意义(P＜0.05),多西他赛组治疗前后心肌酶肌酸激酶CK-MB均值(16.62±10.21)U/L vs(29.94±8.03)U/L,治疗前后比较差异亦有统计学意义(P＜0.05);吉非替尼和多西他赛组间治疗前比较差异无统计学意义(P＞0.05),但治疗后两组比较差异有统计学意义(P＜0.05).射血分数变化:吉非替尼组治疗前后射血分数均值(59.43±8.75)%vs(59.01±7.67)%;多西他赛组治疗前后射血分数均值(60.21±8.97)%vs(59.31±9.21)%,射血分数在治疗前后并未出现明显变化(P＞0.05).结论 吉非替尼与多西他赛在治疗老年晚期肺腺癌有一定疗效;吉非替尼和多西他赛均对心肌一定的损伤;单药化疗将成为老年晚期肺腺癌有效的治疗手段之一.
