摘　　要：[目的]探讨胃癌患者腹腔冲洗液中CEAmRNA、DDCmRNA及PSPHmRNA表达情况与腹膜微转移关系。[方法]采用RT-PCR技术检测80例胃癌患者及16例胃良性肿瘤患者的腹腔冲洗液中的CEAmRNA、DDCmRNA及PSPHmRNA表达水平,并与传统的腹腔冲洗细胞学(PLC)对比分析,寻找与胃癌腹膜微转移有关的肿瘤标志物。[结果]胃癌组分别与胃良性瘤组患者比较,腹腔冲洗液中CEAmRNA、DDCmRNA、PSPHmRNA表达阳性率明显增高(P﹤0.05),其中CEAmRNA最高,其次为DDCmRNA,PSPHmRNA的阳性率较低(P﹤0.05);CEAmRNA、DDCmRNA、PSPHmRNA这3种指标在临床分期、组织学类型、pTNM、淋巴结转移及肝转移间阳性率比较,统计分析显示均有统计学意义(P﹤0.05),而在肿瘤部位方面,差异无统计学意义,随着临床分期的增加,这些肿瘤标志物的表达率也明显升高,有淋巴结及远处转移的患者较未转移的患者阳性率也明显升高;随着肿瘤浸润深度的增加,CEAmRNA、DDCmR-NA、PSPHmRNA及PLC阳性率也明显增加,统计分析显示差异有统计学意义(P﹤0.01)。[结论]采用RT-PCR技术检测胃癌患者腹腔冲洗液中的CEAmRNA及DDCmRNA表达,可以用于预测胃癌患者腹膜微转移。[Objective]To evaluate the relationship of the expression of CEAmRNA,DDCmRNA and PSPHmRNA in the peritoneal lavage fluid and peritoneal metastasis in patients with gastric cancer.[Methods]RT-PCR was used to detect the expression levels of CEAmRNA,DDCmRNA and PSPHmRNA in the peritoneal fluid of 80 cases with gastric cancer and 16 patients with benign tumors,which were compared with the traditional peritoneal washing cytology（PLC）to search tumor markers that were related to gastric cancer peritoneal micro-metastasis.[Results]Compared with benign gastric tumors group,the CEAmRNA,DDCmRNA and PSPHmRNA expression levels in the abdominal fluid of the gastric cancer group were significantly higher（P﹤0.05）,among which CEAmRNA was the highest,followed by DDCmRNA,and PSPHmRNA was with the lowest positive rate（P﹤0.05）;the positive rates of these three indicators in the clinical stage,histological type,pTNM,lymph node metastasis and liver metastasis had statistical significances（P﹤0.05）,while in positions of tumor,the difference was not statistically significant,the expression levels of these tumor markers significantly increased with increasing clinical stage,the positive rates of these markers in patients with lymph node and distant metastases were significantly higher than that in patients without metastasis;with the increasing depth of tumor invasion,positive rates of CEAmRNA,DDCmRNA and PSPHmRNA and PLC also increased significantly,which showed statistical significances（P﹤0.01）.[Conclusion]RT-PCR detection on the expression of CEAmRN and DDCmRNA in peritoneal lavage fluid in patients with gastric cancer can be used to predict the peritoneal micrometastases in patients.
