Together in the fight
against childhood brain cancer

5C is a national research consortium whose purpose is to strengthen and coordinate research within childhood brain tumors in Denmark.

By integrating the interdisciplinary teams at Aarhus University Hospital and Rigshospitalet as well as our other scientific collaboration partners in Denmark and abroad, 5C seeks to create a strong clinical and scientific platform for the development of new strategies within diagnostics, treatment and follow-up of children with brain tumors.

Facts about childhood brain tumors

  • Tumors in the brain and spinal cord are one of the most frequent forms of cancer in children – and the one that costs the most children's lives.

  • Approx. 45 children under 18 are diagnosed with a brain tumor each year.

  • Four out of five children with a brain tumor in Denmark are alive five years after diagnosis. However, survival varies greatly for the more than 100 different sub-diagnoses, and so does the children's level of functioning.

  • Brain tumors are the main diagnosis within childhood cancer with the most late sequelae. Major neurological damage after surgery or radiotherapy is responsible for the most serious late consequences, e.g. learning difficulties, motor problems, visual and hearing difficulties and mental disabilities.

  • Tumors in the brain and spinal cord are usually treated with a combination of chemotherapy, surgery and radiotherapy. The tumors are most often removed in whole or in part by surgery, but there are also tumors that cannot be removed because they are located in places in the brain where the risk of life-threatening damage is too great.
