Brief Summary
The major clinical problem and predominant cause of death after radio-oncological treatment of H+N cancers are loco-regional relapses. This randomized trial tests the hypothesis that dose escalated Intensity Modulated Radiotherapy (IMRT) selectively applied to the macroscopic primary tumor and involved neck nodes - which both in 80% - are hypoxic improves loco-regional control by at least 15% at 2 years. IMRT is combined with concurrent Cis-Platin chemotherapy. Tumor volume which correlates with number of malignant cells as well as tumor hypoxia are important biological parameters which increase radio-resistance, failure of local control and tumor progression. Basing on data of experimental and clinical radiation oncology we consider hypoxia as a useful parameter for pre-therapeutic strati-fication in future randomized radio-chemotherapy trials. In addition, hypoxia imaging by PET can be used for testing the significance of selective dose escalation on hypoxic tumor sub-volumes ("Dose Painting"). As a prerequisite for such innovative studies addressing hypoxia the translational part investigates the following key issues: correlation between the size of total tumor volume (primary, lymph nodes) and hypoxic sub-volume, the spatial shift of the hypoxic sub-volume before start of treatment and the correlation of loco-regional control and hypoxia. Before starting the main study a pre-study to assess the occurrence of radiation induced toxicities is mandatory to be performed. In a step-wise dose-escalation in a cohort-design the safety of dose-escalation should be determined. Step one: 6 patients Step two: 14 patients. In the pre-study the 1st group (6 patients) should be treated with 2.2 Gy up to 77.0 Gy for DEVPT and DEVLK. After evaluation of the toxicity the next 14 patients should be treated by this scheme.
