Abstract
目的:评估腹腔热灌注化疗(hyperthermic intraperitoneal chemotherapy,HIPEC)对腹腔游离癌细胞的杀灭作用,探索腹膜癌细胞学根治的可行性.方法:收集45例腹膜转移癌患者HIPEC前、后的腹腔灌洗液(或腹水)样本,分别行腹腔灌洗液细胞学(peritoneal lavage cytology,PLC)检查;普通RT-PCR及实时定量RT-PCR检测CEA mRNA、CK20 mRNA;化学发光法检测HIPEC前、后患者血清肿瘤标志物CEA、CA125、CA19-9;分析各项指标HIPEC前、后的变化特点.结果:HIPEC前、后PLC检查阳性率分别为93.3%vs. 24.4%(P<0.001);CEA mRNA阳性率分别为97.8%vs. 84.4%(P=0.058);CK20 mRNA阳性率HIPEC前、后均为95.6%(P=1.000).分别有32.5%和30.0%的患者HIPEC后CEA mRNA表达量、CK20 mRNA表达量较HIPEC前显著下降(均P<0.001).HIPEC前、后CEA、CA125、CA19-9阳性率分别为50.0%vs. 23.6%(P=0.016)、52.6%vs. 47.4%(P=0.409)、36.8%vs. 26.3%(P=0.121).结论:HIPEC可有效杀灭腹腔游离癌细胞,为实现腹膜癌的细胞学根治提供了一个可行的方法.
