Health-related quality of life measures in melanoma patients receiving pulsed high-dose intravenous interferon alpha 2b (IFN{alpha}2b)

8536 Background: Major problems of high-dose interferon (HDI) in patients with malignant melanoma (MM) result from side effects and impairment of quality of life (QoL). Up to now it is unclear whether intraveneous (iv), subcutaneous (sc), or both components of HDI treatment are necessary for the efficacy in adjuvant treatment of MM. The adjuvant phase III DeCOG MM-ADJ-5 trial evaluates efficacy, safety, and tolerability of pulsed high-dose intravenous IFNa2b. In this prospective, randomized trial, 3 courses of IFNa2b 20 Mio IU/m2 iv on 5 days a week for 4 weeks repeated every 4 months are compared to the standard HDI regimen. The higher iv dosage produces more toxicity, but for a shorter period of time, since patients in the pulsed treatment arm are 9 months off treatment as compared to the conventional sc treatment with 10 Mio IU/m2 three times a week given for 11 months after 4 weeks of iv therapy. Methods: With a planned recruitment of 600 patients, an interim analysis of QoL has been performed after h...
