Expression and clinical significance of nm23-H1,c-Met and survivin protein in gastric carcinoma tissue / 中华内分泌外科杂志

ABSTRACT

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.
