Treatment of Early-Stage Hypopharyngeal by Radiation Therapy
Cancers arising from the hypopharynx are more commonly seen in developing countries including India, compared to the western countries. Out of all head and neck cancers (HNC), the reported incidence rates are 2–5% in the developed versus 15–30% in the developing countries . In view of its anatomic location, the hypopharynx is a blind spot in the head and neck region of the human body. Unless the patient has serious compromise in the food swallowing activity, a gross change in voice or both, he/she does not report. Hence, more than 70% are diagnosed at an advanced stage, and the early stages I–II are reported in approximately 25% of all hypopharyngeal cancers . Majority of these cancers arise from the pyriform sinus (PFS), whereas post-cricoid cancer is common in an anaemic female. Squamous cell carcinoma is the commonest histologic type. In India, hypopharyngeal cancers constitute more than 10% of all HNC .
