Brief Summary
The study is a prospective randomised clinical phase III trial. Proton therapy is the gold standard in the treatment of low and intermediate grad chondrosarcomas of the skull base. However, high-LET beams such as carbon ions theoretically offer biologic advantages by enhanced biologic effectiveness in slow-growing tumors. Up until now it was impossible to compare two different particle therapies, i.e. proton and carbon ion therapy directly with each other. The aim of this study is to find out, whether the biological advantages of carbon ion therapy mentioned above can also be clinically confirmed.

Outcome Measures
Primary Outcomes (1)
Local-Progression Free Survival (LPFS)
The primary objective of this study is to evaluate, if the innovative carbon ion therapy in chondrosarcomas is not relevantly inferior to the standard proton treatment with respect to the 5 year LPFS rate defined as time from the randomisation to observed local reccurrence. It is assumed that the LPFS rate for the proton therapy is 90%.
