 One hundred and eighty five patients was included in this study. They underwent endoscopic mucosal resection (EMR) for treatment of superficial esophageal cancer more than one year before at our hospital. Synchronous multiple esophageal cancer was identified in 31 patients (22 patients had two lesions, 7 three lesions and 2 four lesions). Type 0-Ⅱc lesion (superficial and slightly depressed type) was frequent and occupied of all primary lesions (47.6%). At the same time, type 0-Ⅱb lesion was most frequent among second esophageal cancers (61.9%). The size of lesions was less than 10 mm in 57% of all secondary lesions. Multiple primary cancers in other organs were frequent among patients with multiple esophageal cancer than patients who had only one cancer in the esophagus. Metachronous multiple esophageal cancer was identified in 23 patients (12.5% of all cases with EMR). Type 0-Ⅱc lesions occupied 59.3% of all lesions. 92.6% of all metachronous multiple esophageal cancer was less than 20 mm in size. 73.9% of all cases was detected within three years after EMR and 55.6% of all cases was existed at distal side to the primary lesions EMR was carried out on 92.6% of all metachronous multiple esophageal cancer lesions and confirmed as mucosal cancer. Malignant lesions in other organs were frequent among patients with metachronous multiple esophageal cancer (34.8%). Metachronous esophageal cancer was significantly frequent among patients with multiple cancer lesion in the esophagus and who had many unstained areas in the esophagus. They were noted at proximal side of the primary lesion (40.5%). All syn-chronous multiple cancer lesion was treated by EMR and they remained within the mucosa.
