中文摘要: |
目的:观察胃癌组织中Fascin 表达和K-ras 突变情况,并分析其与临床病理特征的关系,研究Fascin表达和K-ras突变之间
的相关性,探讨两者在胃癌浸润转移过程中的作用。方法:在108 例胃癌组织中采用免疫组织化学法检测Fascin 表达,采用DNA
测序法检测K-ras突变。结果:108 例胃癌组织中Fascin 表达率为25.00 %,K-ras突变率为11.11 %;胃癌组织中Fascin 阳性表达,
发生淋巴结转移组多于未发生淋巴结转移组(P<0.05),发生远处转移组多于未发生远处转移组(P<0.01);K-ras 突变,发生远处
转移组多于未发生远处转移组(P<0.01);胃癌组织中K-ras 突变和Fascin 表达之间存在相关性,Fascin阳性比Fascin阴性的胃癌
组织更倾向于发生K-ras突变(rp=0.378,P<0.01)。结论:在胃癌组织中K-ras 基因突变和Fascin蛋白阳性表达存在相关性,且与
肿瘤的转移有关。 |

Objective:To observe mutation of K-ras and expression of Fascin in gastric tissues and their relationship with clinical
pathological features, then to analyze the correlation between mutation of K-ras and expression of Fascin.Methods:In 108 cases of
gastric cancer tissues K-ras mutation was detected by DNA sequencing,Fascin expression was detected by immunohistochemical
method.Results:In gastric tissues the mutation rate of K-ras was 11.11 %, the expression rate of Fascin was 25.00 %; The mutation rate
of K-ras in distant metastasis group was higher than without distant metastasis group(P<0.01); The expression rate of Fascin in lymph
node metastasis group was higher than without lymph node metastasis group (P<0.05), and the expression rate of Fascin in distant
metastasis group was higher than without distant metastasis group(P<0.01); There was a correlation between the mutation of K-ras and
the expression of Fascin in gastric tissues, Fascin positive gastric cancer tissue are more inclined to K-ras mutation than Fascin negative
gastric cancer tissue (rp = 0.378, P<0.01).Conclusion:In gastric tissues there is a correlation between the mutation of K-ras and the
expression of Fascin. Both of themplay an important role in the process of invasion and metastasis. |
