COSS-Register

Osteosarcomas and other bone cancers are very rare in childhood and adolescence.
Previous treatment trials have enabled a great deal of experience to be gained with the treatment of these cancers and the chances of a cure for patients to be increased. Many hospitals in Germany, Austria and Switzerland have been collaborating in the Cooperative Osteosarcoma Study Group COSS for over 20 years in an attempt to further improve the treatment of osteosarcoma and other rare bone cancers.

The COSS registry enables a national and international exchange of data to take place about the course of disease in patients with bone cancers. This is the only way to acquire as much knowledge as possible about the causes, frequency, diagnosis, treatment and tumour-related characteristics of these rare cancers. In special treatment situations, the patients’ doctors are also able to obtain an opinion from experienced specialists at the COSS study office or other institutions and reference establishments, enabling patients to benefit from expert opinions and second opinions.
