The clinical course and problem in laser treatment for inoperable case with early gastric cancer were studied. The reason why they were considered to be inoperable were severe heart failure (4cases), severe renal failure (4cases), liver cirrhosis with easy bleeding (3cases), case more than 85 years old (2cases), and pthers (3cases). Six cases had early gastric cancer with absolute indication for endoscopic therapy, that is IIa type and IIc type without ulcer less than 2 cm in size of differentiated adenocarcinoma. Nine cases had early gastric cancer with relative indication. Follow-up study by endoscopic biopsy for more than 6 months was performed in 12 cases out of 15 cases and showed recurrense or remnant in 2 cases. One was absolute indicative case and the other was relative indicative caseit seems that laser therapy is effective for relative indicative cases with early gastric cancer.
