Osteogenic sarcoma is a tumour, which starts in a bone.
Osteogenic means bone forming. No one knows what causes osteogenic
tumours, but we do know that they are not caused by injury. Most
often they arise around the knee but can involve any bone in the
body. Usually older children and adolescents, develop these
Pain in the bone is usually the only symptom that a child has
when this tumour develops. Sometimes an obvious swelling
If a child has pain in a bone an x-ray will probably be taken.
If this suggests there is a tumour, a biopsy will be carried out to
determine exactly what sort of tumour it is. Further x-rays and a
MRI scan of the limb may give an idea of the extent of the tumour
and may be done prior to the biopsy. Blood tests will be done and a
chest x-ray and a bone scan may be carried out to find if the
cancer has spread to other parts of the body. (Refer to section on
tests and procedures)
The exact treatment for Osteogenic sarcoma varies depending on
the age of the child and where the tumour is located. In general,
chemotherapy is given first to kill the main tumour and any
possible metastases. If possible, the tumour is removed later by
surgery. Surgical options for all patients will be
discussed on an individual basis.
After treatment has finished the child will be seen at regular
intervals to monitor growth and development. Treatment may affect
the growth of the limb. If children do have a prosthetic
replacement when they are younger then a new one can be inserted
when they are fully-grown.
