Primary bone tumours are rare, accounting for < 0.2% of malignant neoplasms registered in the EUROCARE (European Cancer Registry based study on survival and care of cancer patients) database. Different bone tumour subtypes have distinct patterns of incidence, and each has no more than 0.3 incident cases per 100 000 per year. Osteosarcoma (OS) and Ewing sarcoma (ES) have a relatively high incidence in the second decade of life, whereas chondrosarcoma (CS) is more common in older age.
