Methods:The study population consisted of 57 advanced ESCC patients.

方法：本研究包含了57例晚期ESCC患者。

Objective: To study the LOH of microsatellite markers' in precancerous lesions of ESCC.

目的：研究ESCC癌前病变微卫星位点的LOH情况。

While in ESCC and dysplasia of esophagus, a whole-cytoplasmic expression of NGAL could be observed.

而在食管癌及食管上皮不典型增生中可见NGAL强阳性着色分布于整个细胞浆。

Conclusion: The mRNA overexpression of MET proto-oncogene is correlated with tumor differentiation in ESCC.

结论：MET原癌基因表达水平与食管鳞癌细胞分化相关。

Combination analysis of methylation status in SFRP genes may has definite value on estimating prognosis of ESCC.

联合检测SFRP基因家族甲基化状态对于食管癌的预后判断有一定指导意义。
