Late radiation-associated dysphagia in head and neck cancer patients: evidence, research and management
In head and neck cancer (HNC) scenario, newer radiotherapy (RT) techniques, such as intensity modulated RT (IMRT), aim to reduce acute and late toxicity without impair tumor response and loco-regional control rates. However, late radiation-associated dysphagia (RAD) remains a major clinical problem and has gained a growing importance in the last few years, especially due to human papilloma virus (HPV)-related HNC favorable prognosis. The aim of this review was to provide clinical information about late RAD.
