Effect of amifostine to prevent radiotherapy-induced acute and late toxicity in head and neck cancer patients who had normal or mild impaired salivary gland function

Abstract

Background: Amifostine has a potential role for salivary gland protection in head and neck cancer patients who had radiotherapy. Material and Method: Sixty-seven head and neck cancer patients were randomized to receive radiotherapy or radiotherapy plus Amifostine. The efficacy of the treatment was determined by a questionnaire evaluating dryness of mouth and the oral comfort, the RTOG/EORTC acute/late radiation morbidity scoring criteria, collection of the whole saliva and the 99mTc-pertecnetate scintigraphy of the salivary glands. Results: Amifostine significantly reduced the mean questionnaire scores from 6.49 to 3.73, the incidence of grade ≥ 2 mucositis from 75% to 36% and acute xerostomia from 82% to 39%. The salivary gland function returned to normal at a rate of 36.3% in the Amifostine group versus 9.1% in the control group. Conclusion: Amifostine is effective in reducing the incidence and severity of acute mucositis, acute and late xerostomia in head and neck cancer patients.
