Patients suffering from head and neck cancer (HNC) have or will develop a second esophageal squamous cell cancer (ESCC) in 5 - 14 %. When a second esophageal neoplasm occurs in a HNC patient, the prognosis is generally determined by the ESCC, and unfortunately it is poor. Prospective clinical studies in Japan, Brazil, Taiwan, France and Germany have shown that screening or surveillance using Lugol chromoesophagoscopy enables early detection of second esophageal neoplasias. Such a surveillance results in a survival benefit for HNC patients. Vice versa, ESCC patients also have a risk of 9.3 - 11.4 % for a head and neck cancer. Periodic otolaryngeal examination and pharyngoscopy is recommended…
