 We conducted this study for the purpose of clarifying the characteristics of cancer residue after endoscopic mucosal resection (EMR) of early gastric cancer. EMR was performed and endoscopically followed up for more than 12 months for 156 lesions in 141 patients. The results were as follows :

 1) Cancer residue was seen in 20 lesions (13%) . It was observed more frequently with incompletely resected lesions, partitively resected lesions, those not indicated for resection, and those more than 10 mm in diameter. Therefore, we should be even more cautious with regard to extending indications.

 2) Eight of twenty lesions (40%) recurred more than 12 months after EMR and some of those were difficult to detect macroscopically. Therefore, frequent follow-up is important not only during the first postoperative year but also in the subsequent years. Furthermore, biopsy of the ulcer scar after EMR should be performed in the subsequent endoscopic examination.

 3) Surgical resection should be chosen if possible for patients with cancer residue because the effectiveness of additional endoscopic treatment has not been sufficiently established yet.
