摘要:
目的探讨CT引导下 125 I放射性粒子植入治疗晚期胰腺癌前后血清肿瘤标志物的动态变化和疗效。方法对19例手术不能切除的晚期胰腺癌施行CT引导下经皮植入 125 I放射性粒子。采用治疗计划系统(TPS)重建胰腺肿瘤的三维立体图像,计算出 125 I粒子植入的数量和剂量分布率,在CT引导下将 125 I粒子植入胰腺肿瘤内。并用放射免疫方法测定 125 I放射性粒子植入治疗胰腺癌前后的血清肿瘤标志物CEA、CA19-9、CA50的浓度。结果治疗后平均2~5d疼痛开始缓解。治疗后1个月CT随访,总有效13例,有效率68.4%;术后3个月CT随访,总有效率为63.2%(12例)。125 I粒子植入1个月后,胰腺癌患者血清中CEA、CA19-9、CA50等肿瘤标志物水平与植入前比较明显降低(P<0.05)。在CA19-9检测中,植入前、CR、PR、SD、PD各组间差别有统计学意义(H=15.349,P<0.05)。结论CT引导下植入 125 I放射性粒子治疗胰腺癌,临床近期疗效确切,具有很好的姑息止痛疗效,是一种安全、有效、并发症少的介入治疗方法;且能有效降低多项肿瘤标志物水平,肿瘤标志物水平对临床疗效有一定的提示作用。
