The epidemiology of hypopharyngeal SCC is essentially the same as that of other squamous cell carcinomas of the aerodigestive tract of the head and neck, and is typically encountered in patients with a long history of smoking tobacco and alcohol consumption 1-2. As such they are more common in males, with perhaps the exception of posterior cricoid tumors which may be more common in women (especially of northern Europe) with Plummer-Vinson syndrome.
===Region===
Human papilloma virus may also play a role, although it is isolated in far fewer patients with hypopharyngeal SCC (16%) compared to oropharyngeal SCC 1-2. See squamous cell carcinomas of the aerodigestive tract of the head and neck for a general discussion.

Overview

The prevalence of hypopharyngeal cancer is estimated to be 2,500 new cases in the U.S annually and hypopharyngeal cancer is a very rare type of cancer. Hypopharyngeal cancer commonly affects patients in 55 to 65 years of age. Males are commonly affected with a hypopharyngeal cancer compared to women. Hypopharyngeal cancer comprises about 7% of all cancers of the head and neck.
