Retrospectiveに観察しえた食道進行癌の2例

Advanced Esophageal Cancer in Which Two Different Patterns of Progression were Retrospectively Observed on X-ray Images, Report of Two Cases

要旨　〔症例1〕は55歳，男性．初診時胃体部多発潰瘍の診断で経過観察となり，7か月後のX線検査でIuに食道進行癌が発見されたが，retrospectiveな検討でも初診時のX線像に所見を見出すことは困難であった．〔症例2〕は64歳，男性．胃潰瘍の診断を受け経過観察となり，その後Im，Iuに進行癌が発見されるまで10か月を要したが，その間の病変部のX線上の所見，殊に伸展不良の程度はほとんど変わらなかった．X線上〔症例1〕は急速な，〔症例2〕は比較的緩徐な経過を呈したと思われ，食道癌の発育・進展という問題に対し，何らかの示唆を与えると思われたので報告した．

　We observed two different patterns of esophageal cancer progression in two patients.

　(Case 1) A 55 year-old man. He visited our department and was diagnosed as having multiple stomach ulcers. In the follow up over a period of seven months, an advanced esophageal carcinoma was found incidentally. The series of x-ray images taken at the initial visit were reviewed. However, it was difficult to spot the lesion concerned.

　(Case 2) A 64 year-old man. A stomach ulcer was pointed out during his initial visit to our department. During the course of his treatment over a period of ten months, an esophageal cancer was suspected. Poor distensibility at the lesion site was still present to the same degree as it was in the previous examinations.

　X-ray images taken during the course of treatment suggested that, compared to growth rate in Case 2, the carcinoma in Case 1 followed a pattern of rapid growth.

　Therefore, there might exist two different patterns of esophageal cancer progression, rapid growth and slow growth.
