胃溃疡是否能发生癌变,在世界范围内该问题迄今未得统一认识,争论不休。传统观念认为溃疡病是可以癌变的,早在1939年Grureilhier首先阐述了慢性溃疡和癌的临床与病理区别,并认为溃疡癌变是可能的,以后许多学者如Newcomb,小黑氏等也论述此观点,而近十余年来Palmer等认为:溃疡病是不能癌变的,胃癌不能发生在溃疡的基础上,而溃疡是胃癌被胃液消化的后果。Backus则认为胃溃疡与胃癌是互不相关的不同疾病。究竟胃溃疡是否 Whether or not gastric ulcers can become cancerous, the issue has so far been unrecognized and debated. The traditional concept is that canker can be cancerous. As early as 1939, Grureilhier first described the clinical and pathological differences between chronic ulcers and cancers, and considered that ulceration is possible. Many scholars such as Newcomb and Xiaohei also discussed this point later. In the past decade or so, Palmer et al. believe that ulcer disease cannot be cancerous, gastric cancer cannot occur on the basis of ulcers, and ulcers are the consequences of gastric cancer being digested by gastric juice. Backus believes that gastric ulcer and gastric cancer are different diseases that are not related to each other. What is the stomach ulcer?
