摘　　要：目的:评估腹腔冲洗细胞学检查和CEAmRNA检测对胃癌预后的临床意义。方法:收集胃癌及对照(胃良性疾病)组患者的腹腔冲洗液标本,进行腹水细胞病理学和CEA巢式RT-PCR检测,并评价其与临床病理参数的关系。结果:腹水肿瘤细胞检测阳性率为30.3%,CEA巢式RT-PCR检测阳性率为48.5%,其结果与肿瘤分化程度、浸润深度、淋巴结转移和TNM分期有关(P<0.05),而与肿瘤的大小无关(P>0.05)。对照组腹水肿瘤细胞和CEA检测阳性率均为0。结论:胃癌患者腹腔冲洗液CEAmRNA检测可作为判断胃癌侵袭转移、术后复发情况及患者预后的参考指标之一。Objective： To evaluate the significance of peritoneal lavage cytology and CEA mRNA detection for clinical assessment of prognosis of gastric cancer. Methods： Peritoneal irrigating solution samples in 66 patients with gastric cancer and 12 innocent ones were collected, peritoneal lavage cytology and CEA mRNA nest-RT-PCR detection were used to exam the exfoliated cancer cells, meanwhile relationships between positive results and relative clinico-pathological parameters were evaluated. Results： The positive rate of HE was 30.3%, and that of nest-RT-PCR was 48.5% When the degree of histologic differentiation of gastric cancer became poorer, deeply invasion increased, stage of TNM upgraded and lymph node metastasis appeared, positive rate in peritoneal tavage increased significantly （P〈0.05）. But it was not related to the size of the tumor（P〉0.05）. Concluslon： The methods may act as the standard for judging the invasive and metastatic state of gastric cancer and forecasting the prognosis of patients with such disease.
