This book will prove essential reading for all who are involved in the care of children with liver tumors. All aspects of an impressive success story are covered, disclosing how the outcome of a previously devastating disease has been so dramatically improved. Their principal goal in Hepatic Tumors in Children is to provide the reader with a complete update on this complex and rapidly evolving field. International controlled trials have played a key role in these advances, and many leading figures in the trials are among the editors and authors of this book. This has been achieved through a much better understanding of the biology of disease, improved diagnostic procedures, refined methods of pretreatment tumor staging, the implementation of highly efficient chemotherapy and surgery, detailed monitoring of toxicity, and careful follow-up strategies. The field of liver tumors in children, and in particular hepatoblastoma in infants and young children, has seen tremendous therapeutic advances over recent years.
