 Three thousand patients with head and neck cancer underwent endoscopic screening with iodine staining and esophageal cancer was detected in 8.7 % of these patients. The number of patients with double cancer was 317 cases, which consisted of 60.9 % synchronously, 28.1 % metachronously with detection of head and neck as the primary cancer, and 10.1 % with esophageal cancer as the primary one. The largest location of head and neck cancer was the hypopharynx. The rate of smoking was 77.6 % and the Brinkmann index was 1053.0. In addition, the rate of drinking was 83.0 % and the Sake index was 104.1. Regarding the type of macroscopic appearance, 0-IIc was found in 47.3 % and 0-IIb in 20.5 %. The largest diameter of tumor was 11~20 mm in 30.7 % and the depth of wall invasion of “m1 and m2” occupied 49.1 %. Regarding the number of unstained areas, the so-called “multiple small iodine unstained lesions” type was largest in 29.3 %, and multiple esophageal cancer was found in 32.8 %. For treatment, 58.7 % of patients with “m1 and m2” underwent EMR, but, 54.8 % with “m3 and sm1” and 76.6 % with “sm2 and sm3” underwent surgical operation. Finally, radiation and/or chemotherapy was performed in 12.0 % of all patients.
