胃癌是一常见的胃肠道肿瘤,其中治疗方案及其效果是临床关注的问题,这是不仅涉及肿瘤切除的彻底性和辅助治疗的合理应用,还与肿瘤的类型、分化程度、病理分期、浸润深度和范围以及转移等因素有关。近期的胃癌分子生物学研究已提示不少胃癌基因、粘附分子、肿瘤相关蛋白酶及其抑制剂等与胃癌的预后有关,在考虑一个理想的综合 Gastric cancer is a common gastrointestinal cancer, and the treatment plan and its effect are clinical concerns. This is not only the rational application of thoroughness and adjuvant treatment of tumor resection, but also the type of tumor, differentiation degree, pathological stage, Infiltration depth and range and transfer and other factors. Recent studies on molecular biology of gastric cancer have suggested that many gastric cancer genes, adhesion molecules, tumor-associated proteases, and their inhibitors are involved in the prognosis of gastric cancer, considering an ideal synthesis
