结直肠癌是消化道恶性肿瘤之一,近年在我国结直肠癌的发生率呈明显上升趋势。如何早期发现、早期诊断以及早期采取多种多样的、更有效的治疗手段,使结直肠癌患者获得更高的生存率和更长的生存期,一直是国内外学者重要的研究方向。因此对结直肠癌进行基因变异检测及相关蛋白研究成为该领域的焦点。国内外的研究显示,结直肠癌靶向治疗药物西妥昔单抗为表皮生长因子受体 Colorectal cancer is one of the digestive tract malignant tumors in recent years, the incidence of colorectal cancer showed a clear upward trend. How early detection, early diagnosis and early adoption of a variety of more effective treatment to make colorectal cancer patients have a higher survival rate and longer survival has been an important research direction of scholars at home and abroad. Therefore, colorectal cancer genetic mutation detection and related protein research become the focus of the field. Domestic and international research shows that colorectal cancer targeted drug cetuximab is epidermal growth factor receptor
