要旨 strip biopsyの臨床応用初期の症例が,治療後7年ほどを経過した現時点において,5年以上経過した症例について,その成績を検討した.長径2cm以下の潰瘍を有さない深達度mの高分化型腺癌を対象とした.strip biopsyによる治療の後,5年以上を経過した症例のうち,筆者らの定義による局所完全切除が得られた34例では,他病死1例,連絡不能3例を除く30例は,生存が確認されている.また,部分切除となり,その後にレーザー照射などを追加していた10例では,3例の他病死をみるものの,7例は生存している.本検討の結果より,早期胃癌に対するstrip biopsyによる治療は,慎重に限定した適応内で施行し確実な効果判定を行えば,良好な長期予後を期待しうる方法であった.
Seven years have passed since our first therapeutic experience of strip biopsy for early gastric cancer. We present here the results of follow-up studies on patients with early gastric cancer treated by strip biopsy. Subjects were those patients followed-up for five years or longer after complete resection by strip biopsy (34cases) or after an additional endoscopic therapy after partial resection by strip biopsy (10cases).
Thirty-seven of those 44patients are currently alive.
Four died of malignancies of other organs and 3 others dropped out from the follow-up because of change of address. Thus, endoscopic follow-up was completed for 33patients. No residual lesion was demonstrated.
In conclusion, strip biopsy is considered to be an effective treatment, when applied appropriately, for early gastric cancer.
