Chondrosarcoma is a rare neoplasm, as only 130 people per year are affected in germany. The aim of this disseration was to analyse the oncological outcome of 155 patients, treated for a chondrosarcoma in the Robert-Rössle-Klinik from 1970 to 2003. Furthermore prognostic parameters were explored. The overall-survival was 68,8% after 5 years and 64,4% after 10 years. The event-free-survival was 58,6% after 5 years and 48,3% after 10 years. Local recurrence and the occurrence of metastases lead to a reduced overall-survival. Grading, the age at the time of diagnosis and the achievement of a wide resection were proofed to be indepentend risk-fators for overall-survival. Concerning the event-free-survival the tumor volume, the grading as well as an intralesional resection were identified as independing risk-factors. The site of the tumor had no influence on neither the overall-survival nor the event-free-survival. The inclusion of the prognostic factors can lead to a differenciated treatment of this rare tumor entity.
