This study aims to investigate the molecular characteristics of Chinese gastric cancer patients. In our study, the , , and mutation status of 485 GC patients were analyzed by Sanger sequencing. Kaplan-Meier analysis was used to plot survival curves according to different genotypes. The results show that the frequency of , and mutations were 4.1%, 1.2% and 3.5%, respectively. mutations were significantly concentrated in stage III and IV gastric cancer (=0.009). G12V mutation carriers have much shorter OS than other mutation carriers and wild-type group patients (=0.013). In conclusion, only the G12V mutation has an adverse effect on patient survival.
本研究旨在调查中国胃癌患者的分子特征。在我们的研究中，通过桑格测序分析了485例胃癌患者的 、 和 突变状态。采用Kaplan-Meier分析根据不同基因型绘制生存曲线。结果显示， 、 和 突变的频率分别为4.1%、1.2%和3.5%。 突变显著集中在III期和IV期胃癌（=0.009）。G12V突变携带者的总生存期比其他突变携带者和野生型组患者短得多（=0.013）。总之，只有 G12V突变对患者生存有不利影响。
