In Kurume University Hospital, follow-up study more than 1 year in the endoscopic Laser therapy for early gastric cancer (34 leseions, 26 cases) was analysed on the size and endoscopic features of lesions.
Disappearance rate of cancer cells seemed higher in the protruded type and/or small lesions than the depressed and/or large ones after initial Laser irradiation. Cancer cells was detected in none of protruded lesions less than 10mm in diameter.
These findings suggested that the endoscopic Laser therapy would be a curative therapy in these cases. Moreover, additional Laser irradiation was effective in the case of recidual cancer cells.
