早期胃癌に対する内視鏡治療の適応と限界について

抄録

Early gastric cancers (97 lesions with 86 cases) of high surgical risk were treated under endoscopy in 1981 to 1989 in our institute.
Indication of endoscopic treatment for ealrly gastric cancer was divided into three groups. The first group belongs to the lesion of radical cure, what we call absolute indication. The second group is relative indication-carried out to over 75 aged patients or to patients with no wish for operation. The last one is a case of high surgical risk or rejection for operation.
We think we should first choose mucosal resection method in the treatment of early gastric cancer, followed by various kinds of tumor destructive modalities (laser, microwave, ethanol local injection etc) if the case is in difficulty in delineation of the cancer lesion or wide spread or invasion into submucosa or accompanied with ulcerative change.
But we have to investigate in many aspects furthermore to achieve complete irradication of early gastric cancers.
