Clinical features of molecular pathology of solid tumours in childhood.
The outlook for children with cancer has improved substantially over the past 20 years, with over three-quarters of children now surviving in the long term. Better use of existing cytotoxic drugs and supportive care have made large contributions, but some of the improvement in survival is due to a greater knowledge of childhood cancer at the cellular and molecular levels. As in leukaemias, several childhood solid tumours carry balanced chromosomal translocations, resulting in fusion genes that encode chimeric proteins with new oncogenic properties. Many of these fusion genes, and other genetic aberrations are tumour specific and are related to outcome. Tumour biology now plays an important part in identifying appropriate treatment through more accurate diagnoses and new risk stratifications based on molecular markers.
