Esophageal cancer has a poor prognosis because it is difficult to detect in its early stages and, even if an operation is possible, the postoperative quality of life is much impaired. An early diagnosis can lead to a good prognosis and enables treatment by endoscopic mucosal resection (EEMR), contributing to a postoperative good quality of life. As head and neck cancers are known to have a high risk of concomitant esophageal cancer, endoscopic screening with iodine staining was performed on 788 patients with head and neck cancers. Among them, 93 cases of esophageal cancers (11.8%) and 23 cases of gastric cancers (2.9%) were detected. Seventy-two cases (77.4%) of the 93 esophageal cancers were superficial cancers limited to the submucosal layer. Twenty cases, treated by EEMR, had a good postoperative course without local recurrence. We suggest that endoscopic screening for esophageal cancer should be performed on all patients with head and neck cancers, because it allows early detection and a good prognosis, and the treatment can be completed by endoscopic maneuver.
