Chromosome deletion predicts aggressive neuroblastoma

When genes are deleted on a particular section of chromosome 11, the result is an aggressive form of the childhood cancer neuroblastoma. A new study suggests that detecting this genetic deletion during the initial evaluation of children with neuroblastoma may indicate to physicians that they shou...
