摘要: 目的:检测SERPINE1 mRNA在食管鳞癌中的表达并评价其临床意义。方法:采用组织微阵列和RNAscope原位杂交技术检测236例食管鳞癌组织及其配对手术切缘正常组织中SERPINE1 mRNA的表达水平,分析其表达与临床病理指标及预后的相关性。结果:在23.7%(56/236)的食管鳞癌组织中有SERPINE1 mRNA的高表达,而在癌旁正常组织中无表达。SERPINE1 mRNA表达水平与性别、肿瘤分级、浸润深度及临床分期均显著正相关(r分别为7.939、6.618、10.939、6.671,均为P<0.05)。Kaplan-Meier生存曲线显示SERPINE1 mRNA高表达患者的生存时间显著短于低表达患者(P<0.05)。多因素Cox回归分析表明,SERPINE1 mRNA高表达是食管鳞癌患者不良预后的独立预测因素。结论:SERPINE1 mRNA在食管鳞癌组织中表达升高,其高表达与食管鳞癌患者预后不良相关,有可能作为食管鳞癌预后评估的分子标志。

Abstract: OBJECTIVE: To investigate expression status and clinical relevance of SERPINE1 mRNA in esophageal squamous cell carcinoma (ESCC) tissues. METHODS: Expressions of SERPINE1 mRNA were determined using tissue microarrays and RNAscope in situ hybridizations in surgically-resected tumor tissues and adjacent normal epithelia from 236 ESCC patients. Relationships between the mRNA expression and clinicopathological characteristics as well as prognosis were analyzed. RESULTS: Increased expression of SERPINE1 mRNA was observed in 23.7% (56/236) of the tumor tissues. However,there was no expression of SERPINE1 mRNA in normal tissues which were adjacent to the carcinomas. The increased expressions were positively correlated with genders,histological grades,T stages and clinical stages (r=7.939,6.618,10.939,6.671,respectively;each P<0.05). Kaplan-Meier survival curves show that patients with high expressions of SERPINE1 mRNA had shorter survival times than those with low expressions (P<0.05). Cox multiple regression analyses indicate that SERPINE1 mRNA expression was an independent prognosis factor in ESCC. CONCLUSION: SERPINE1 mRNA was expressed highly in ESCC tissues. Our data indicate that the expression may serve as a molecular biomarker for predicting poor prognosis of ESCC patients.
