摘要:

背景与目的:胃癌术后复发转移严重影响患者生存情况,SOX基因是经典Wnt信号通路的调控因子,其在胃癌术后复发及转移过程中可能发挥重要作用。本研究旨在探讨胃癌术后复发、远处转移患者肿瘤组织中SOX-2β-catenin表达情况,探讨两者在胃癌术后复发及转移的作用。方法:采用免疫组化方法检测71例经手术切除胃癌患者的肿瘤组织中SOX-2β-catenin蛋白表达情况,并分析其与临床病理特征和无病生存时间(disease free survivalDFS)的关系。结果:SOX-2在胃癌中的表达与胃癌复发转移、淋巴结浸润及分化程度有关(P=0.011P=0.036P=0.034),与患者性别、年龄及T分期无关。β-catenin在胃癌中的表达与胃癌复发转移、淋巴结浸润及T分期有关(P=0.025P=0.014P=0.026),与分化程度、患者性别及年龄无关。且二者均呈阳性表达者其术后复发转移率高于任意单阳性者,复发转移率分别为84%(21/25)66.7%(24/36),二者均阴性表达者其复发转移率为30%(3/10)。生存分析显示SOX-2和β-catenin的表达与患者DFS相关。结论:SOX-2β-catenin表达可能是胃癌术后复发转移有效的预测因子,两者联合检测有利于预测胃癌患者术后复发转移。

Abstract:

Background and purpose: The recurrence and metastasis of gastric cancer seriously affect survival in patients. SOX gene as a regulatory factor of the classical Wnt pathway, may play an important role in the process. This study was to explore the expression of stem cell marker SOX-2 and β-catenin in gastric cancer and to analyze the relationship with recurrence and metastasis after operation. Methods: Immunohistochemistry was used to detect the expression of SOX-2 and β-catenin in 71 tumor samples from 71 cases after surgery for gastric cancer. The correlation between SOX-2 and β-catenin expression and the clinicopathological characteristics of gastric cancer and disease-free survival was analyzed. Results: The SOX-2 protein expression was associated with metastasis, lymph node infiltration or differentiation (P=0.011, P=0.036, P=0.034) in the 71 gastric cancer, but not with gender, age or T stage.β-catenin expression was correlated with metastasis, lymph node invasion or T stage (P=0.025, P=0.014, P=0.026), but was not related to differentiation, gender or age. The survival analysis showed that SOX-2 and β-catenin expression was closely associated with prognosis of patients, and metastatic rate in positive expression was higher than that in negative expression. Conclusion: The expression of SOX-2 and β-catenin is associated with the development, recurrence, metastasis of gastric cancer and may be used as a useful prognostic parameter to predict overall survival.
