贲门癌在我国属常见之肿瘤,根据阜外医院病例统计,贲门癌与食管癌的比例约为1:3。但此病由于其部位特点,过去有的作者将其归入胃癌的范畴,有的又将其和食管癌混在一起分析,而较少单独加以讨论。我们同意吴英恺氏等的意见,贲门癌既不同于一般胃癌,又不完全同于食管癌,而应当单独列为一类疾病进行研究。 Cardiac cancer is a common tumor in China. According to the statistics of Fuwai Hospital, the ratio of cardiac cancer to esophageal cancer is approximately 1:3. However, due to its site characteristics, some of the past authors classified it as a category of gastric cancer, and some of them were mixed with esophageal cancer analysis, but were not discussed separately. We agree with Wu Yingwei’s opinion that cardia cancer is different from normal gastric cancer and is not exactly the same as esophageal cancer. It should be classified as a single disease for research.
