Phase I Trial From GRID 18F-FDG-PET Biological Imaging-guided Intensitymodulated Radiotherapy (BG-IMRT) With Patients With Recurrent or New Head or Neck Tumor in Previously Radiated Area

Phase I Trial From GRID 18F-FDG-PET Biological Imaging-guided Intensitymodulated Radiotherapy (BG-IMRT) With Patients With Recurrent or New Head or Neck Tumor in Previously Radiated Area

This trials examines the feasibility of GRID-therapy combined with biologically imaging based IMRT (BG-IMRT). Within this trial, the strict toxicity parameters of primary treatment of head and neck tumors are used. The GRID and BG-IMRT technique might be possible to reduce the total radiation dose 2 to 3 times.

Inclusion Criteria:

• Recurrent or new head or neck tumor
• 18 years or older
