 A retrospective evaluation was made concerning 274 patients with esophageal cancer who underwent esophagectomy between 1994 and 1998. Among them, multiple primary esophageal cancers were detected in 59 patients (21.5%), but, in patients with superficial esophageal cancer who underwent endoscopic mucosal resection, the incidence of multiple primary esophageal cancer was 18.7%. This percentage was considerably less than that of surgically resected cases. The accessory lesions tended to occur near the main lesions, and almost all accessory lesions were mucosal cancer. The incidence of head and neck cancers among the multiple esophageal cancer cases was significantly higher than that of single esophageal cancer cases. In the diagnosis of esophageal cancer, it is necessary to observe the entire esophagus with iodine staining.
