Preventing radiation induced xerostomia

Summary ion induced xerostomia is a frequent consequence of radiotherapy (RT) for head–neck cancer (HNC) patients, when parotid glands are included in the radiation fields. Although early appearing xerostomia may be alleviated with the use of pilocarpine, persistent chronic xerostomia affects more than 70% of HNC patients treated with post-operative or radical radiotherapy and significantly impairs the quality of life potentially cured patients. The present manuscript reviews and discusses the current technological (conformal and intensity modulated RT) and pharmacological (amifostine) developments aiming to prevent the severity and reduce incidence of both acute and late radiation xerostomia in patients with HNC.
