 We conducted this study to clarify 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 193 lesions in 178 patients. The results were as follows: 1) Cancer residue was seen in 21 lesions (11%). 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. 2) One third of the lesions 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) Mucosal cancer whose lateral cut margin was positive recurred in the mucosa. 4) It was suggested that EUS was effective in diagnosing small submucosal invasion of reccurent cancer.
