胃癌组织中nm23-H1、c-Met和survivin蛋白表达及临床意义

目的 探讨胃癌组织中nm23-H1、c-Met、survivin蛋白表达及其临床意义.方法 对50例胃癌蜡快标本,运用S-P免疫组化技术检测nm23-H1、c-Met、survivin蛋白表达情况.并分析各基因表达与胃癌组织的分化程度、浸润深度、淋巴结转移、TNM分期及转移和复发之间的关系.结果 nm23-H1、Cmet、survivin蛋白表达率分别为46%、72%、80%,胃癌TNM分期、淋巴结转移与nm23-H1蛋白低表达有密切关系,c-Met蛋白的高表达与胃癌TNM分期、淋巴结转移有密切关系,survivin蛋白的高表达与胃癌分化程度、TNM分期、淋巴结转移有密切关系,nm23-H1蛋白表达与survivin表达呈负相关,c-Met蛋白的表达与survivin表达旱正相关.结论 nm23-H1蛋白低表达和c-Met、survivin高表达对于早期诊断和预后分析有重要指导意义,据其表达开展有选择性地基因治疗应有一个良好的应用前景.

Expression and clinical significance of nm23-H1,c-Met and survivin protein in gastric carcinoma tissue

Objective To Study the expression and clinical meaning of nm23-H1,c-Met and survivin protein in gastric carcinoma tissue.Methods Expression of nm23-H1,c-Met and survivin protein in 50 paraffin block samples of gastric carcinoma were detected by S-P immunohistochemistry technology.The relationship of expression to tumor differentiation degree,infiltration depth,lymph node metastasis,TNM stage,tumor metastasis and reeidivation were analyzed.Results The positive expression rates of nm23-H1,c-Met and survivin protein were 46%,72% and 80%,low nm23-H1 protein expression and high c-Met protein expression correlated tightly with TNM stage and lymph node metastasis of gastric carcinoma,high survivin protein expression correlated tightly with differentiation degree,TNM stage and lymph node metastasis of gastric carcinoma,there was a inverse correlation between nm23-H1 protein expression and survivin,but a direct correlation between c-Met and survivin.Conclusions Low nm23-H1 protein expression and high c-Met and survivin expression has important guidance significance of making a early diagnosis and judging prognosis.Selective gene therapy guided by these may be helpful.
