目的

探讨胃癌组织中Her-2的基因扩增比例与胃癌临床病理及预后的相关关系。

方法

采用荧光原位杂交技术(FISH)法检测62例胃癌组织中Her-2基因扩增状态,结合临床病理及总生存率,分析Her-2基因与临床病理参数、预后的相关性。

结果

62例胃癌组织中Her-2阳性10例(16.1%),阴性52例(83.9%)。Her-2在胃癌组织中基因扩增与患者病理T分期、N分期、分化程度、远处转移有关(P < 0.05);而与性别、临床发病年龄、部位、CEA增高(> 5 μg/L)、脉管受侵无关;Kaplan-Meier分析显示Her-2基因扩增阳性组患者生存时间较阴性组短,差异有统计学意义(P < 0.05)。

结论

胃癌原癌基因Her-2与患者的临床及病理特征、5年生存率有关。

Objective

To detect the amplification proportion of the Her-2 gene, explore the association of the Her-2 gene amplification with the clinical and pathological meaning and the prognosis in gastric cancer.

Methods

Sixty-two cases of gastric cancer were detected by fluorescence in situ hybridization(FISH), analyzed the correlation of the Her-2 gene amplification and clinicopathologic parameters and the prognosis in gastric cancer.

Results

The amplification of Her-2 gene existed in 10 cases (16.1%) while 52 cases had no Her-2 gene amplification (83.9%). Her-2 gene amplification was associated with histologic T grade, regional lymph node and stage, and distant metastasis (P < 0.05). No association was found with sex,age,site of tumor, vessel infiltrating and CEA > 5 μg/L. By Kaplan-Meier analysis, the survival time was shorter in the patients with positive Her-2 amplification than in those with negative Her-2 amplification.

Conclusion

The amplification of Her-2 gene is significantly related with the clinical and pathological characters and overall 5-year survival rate in gastric cancer.
