In this study, we examined the expression of esophageal cancer-related gene 4 (ECRG4) mRNA and evaluated its clinical significance in esophageal squamous cell carcinoma (ESCC). ECRG4 mRNA expression was quantified by real-time RT-PCR in 63 ESCC and corresponding normal esophageal mucosal samples. ECRG4 mRNA expression levels were significantly lower in ESCC tissues compared with corresponding normal esophageal mucosa (P<0.0001), in patients with locally invasive T2-4 tumors compared with less invasive T1 tumors (P=0.0229) and in stage 4 tumors compared with stage 0-3 tumors (P=0.0120). Furthermore, low ECRG4 mRNA expression levels were associated with significantly shorter survival after surgery compared with high ECRG4 mRNA expression levels (P=0.0150) in ESCC patients. On the basis of multivariate analysis, we conclude that ECRG4 mRNA expression level could be a candidate for an independent prognostic factor for ESCC patients.
在本研究中，我们检测了食管癌相关基因4（ECRG4）mRNA的表达，并评估了其在食管鳞状细胞癌（ESCC）中的临床意义。通过实时逆转录聚合酶链反应（RT-PCR）对63例ESCC组织及相应的正常食管黏膜样本中ECRG4 mRNA的表达进行定量分析。与相应的正常食管黏膜相比，ESCC组织中ECRG4 mRNA的表达水平显著降低（P<0.0001）；与浸润性较小的T1期肿瘤患者相比，局部浸润性T2-4期肿瘤患者中ECRG4 mRNA的表达水平较低（P=0.0229）；与0-3期肿瘤相比，4期肿瘤中ECRG4 mRNA的表达水平较低（P=0.0120）。此外，与ECRG4 mRNA高表达水平的ESCC患者相比，低表达水平的患者术后生存期显著缩短（P=0.0150）。基于多因素分析，我们得出结论，ECRG4 mRNA表达水平可能是ESCC患者独立预后因素的一个候选指标。
