要旨●過去15年間に当科および関連施設にて診断された原発性空・回腸癌19例を対象とし,臨床像,小腸X線造影所見を検討した.平均腫瘍径は43.4mmで,病変部位は空腸12例,回腸7例であった.肉眼型は潰瘍型が14例と最多で,すべて輪状狭窄型であった.TNM分類Stage IVの割合が高く(32%),5年後のOS(overall survival)は58%,TNM分類Stage IVはOS,EFS(event-free survival)の,空腸,潰瘍型はEFSの予後不良因子であった.小腸X線造影所見では輪状狭窄型の全例,および全周性の隆起型病変でnapkin-ring sign,口側腸管の拡張像を,輪状狭窄型はさらに全例でoverhanging edgeを認めた.以上より,原発性空・回腸癌の予後不良因子はTNM分類Stage IVであり,輪状狭窄型および全周性の隆起型病変は特徴的な小腸X線造影検査所見を有していた.
