目的 分析KRAS基因突变在左半结肠、右半结肠癌分布几率的差异性。方法 回顾性分析我院病理科分子实验室2015年到2017年间接收的537例结肠癌手术标本,用ARMS-PCR法进行了KRAS基因的检测,并对左右半结肠腺癌KRAS基因突变比例进行χ2检验,P<0.05为差异有统计学意义。结果 537例中有187(34.82%)例为右半结肠腺癌,左半结肠腺癌有350(65.18%)例。KRAS基因突变检测阳性例数为240例,阳性率为44.69%;右半结肠腺癌KRAS基因突变阳性数为114例,阳性率为60.96%;左半结肠癌KRAS基因突变阳性数为126例,阳性率为36.00%。双侧结肠腺癌KRAS基因突变差异有统计学意义。结论 右半结肠癌的患病例数低于左半结肠癌,右半结肠癌KRAS基因突变阳性率较左半结肠癌高,本研究为区分左右半结肠癌的分子靶向治疗提供了数据支持。
Objective To analyze the differences distribution of KRAS gene mutations in the left hemi colon cancer and right hemi colon cancer. Methods Retrospectively to analyse the 537 colorectal cancer patients who were received by our molecular laboratory of pathology from 2015 to 2017, ARMS-PCR method was used to detect the KRAS gene. The ratio of KRAS gene mutation in left and right hemi colon cancer was tested by χ2 test, P<0.05 was considered statistically significant. Results There were 187(34.82%) patients with right hemi colon cancer; and there were 350 (65.18%)patients with left half hemi colon cancer. The KRAS positive patients were 240 cases, which were 44.69% in total. The positive patients with right hemi colon cancer were 114 cases which had a higher rate of 60.96%, the left hemi colon cancer patients were 126 cases with a lower rate of 36.00%. Conclusion The number of right hemi colon cancer was lower than the number of left hemi colon cancer. And the KRAS gene mutation in right hemi colon cancer had more positive than left hemi colon cancer. This study provides a number aid for treating right and left colon cancer in the subsequent molecular targeted drug therapy.
