胃癌的分型是长期有争论的问题,所以分类命名比较混乱,描述性的组织学类型如腺癌、乳头状腺癌、实体癌、硬癌和胶样癌等和其生物行为及预后等其他特征很少有联系,Stout和AcKermann等早已否认胃癌组织学分类的意义。胃癌的预后较差,诊断胃癌的病人五年生存率只有10～15％。胃癌的治疗主要靠外科手术切除,术后五年生存率不过30％。总的来说胃癌的分型及预后都不理想,近年来提出不少新的分型方法,现着重讨论其与预后的关系。 Lauren将胃癌分为两个主要类型:
The classification of gastric cancer is a long-standing controversial issue, so the classification and naming are rather confusing, descriptive histological types such as adenocarcinoma, papillary adenocarcinoma, solid cancer, hard cancer, and colloid cancer, and their biological behavior and prognosis, among others. Features are rarely linked, and Stout and AcKermann have long denied the significance of histological classification of gastric cancer. The prognosis of gastric cancer is poor. The five-year survival rate of patients diagnosed with gastric cancer is only 10 to 15%. The treatment of gastric cancer relies on surgical resection, and the postoperative five-year survival rate is only 30%. In general, the classification and prognosis of gastric cancer are unsatisfactory. In recent years, a number of new classification methods have been proposed. The relationship between prognosis and prognosis is discussed. Lauren divides stomach cancer into two main types:
