Registry For Children, Adolescents And Adults With Osteosarcoma And Biologically Related Bone Sarcomas

The Registry For Children, Adolescents And Adults With Osteosarcoma And Biologically Related Bone Sarcomas (COSS-Registry) is a non-interventional, multicentric, international, clinical and epidemiologic patient registry. The COSS-Registry collects key data on osteosarcomas or biologically related bone sarcomas. With that data collection we want to gain new scientific insights and results about this tumor disease, prognosis, surveillance and long-term effects.

Besides the data collection we would also like to foster the collection of biomaterial (tumor specimen and blood samples) for scientific research.

The stored material will be used to perform cell and molecular biological analyses to identify the causes of osteosarcoma, the prognosis and possible new treatment options.

As a starting point the donated biomaterial of registered patients will be analyzed firstly for the presence of a tumor predisposition by germline mutations.

In case of detected genetic variations that are related to the tumor disease and which may affect the patient's health and follow-up care (because of the potentially increased risk of developing other malignant tumors), affected patients will be informed and referred to genetic counseling.

Registry patients will be asked at the time of diagnosis if they wish to be informed about germline variants detected as part of the study procedures.
