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.
Objective:The aim of this study was to investigate the clinical characteristics and radiographic findings of primary small-bowel adenocarcinoma(PSBA). Methods:We identified 19 PSBA cases diagnosed at our institutions from 2006 to 2021, and their clinical characteristics and radiographic findings were investigated retrospectively. Results:The mean tumor size was 43.4mm. Twelve lesions were located in the jejunum and seven lesions in the ileum. Macroscopically, 15 lesions appeared as ulcerating type, of which 14 were circular stenosis type. In terms of the tumor-node-metastasis(TNM)classification, six(32%)cases were in Stage IV. Stage IV of TNM classification was a poor prognostic factor for both overall survival and event-free survival. In small-bowel radiographic findings, all circular stenosis-type lesions had napkin-ring sign, intestinal expansion of the oral side of the tumor, and overhanging edge. Conclusions:The poor prognostic factor of the PSBA include Stage IV of TNM classification. The radiographic procedures were useful for the diagnosis of PSBA with circular stenosis type.
