The purpose of Diagnostic and Therapeutic Advances in Pediatric Oncology for the Cancer Treatment and Research Series is to provide an up-to-date summary of how recent advances in cancer research are being applied to the care of children with solid tumors. The interface of cancer research with clinical practice in pediatric oncology has never been more intimate than today. While researchers are identifying oncogenes and tumor suppressor genes and are studying their specific functions, clinicians are using knowledge of oncogenes and tumor suppressor genes for diagnosing cancer in children, for therapeutic decision-making purposes, and for prognostic purposes. The first three chapters in this book describe models for understanding the causes of childhood cancer that were perhaps initially identified by clinicians and that are now being studied and understood by researchers. These chapters will describe research evidence that supports roles for the involvement of normal developmental regulatory genes in childhood oncogenesis, of abnormal immune regulation in childhood oncogenesis, and of heredity in childhood oncogenesis. The next eight chapters are devoted to descriptions of the appli cation of new research developments to clinical practice with reference to the most common forms of solid tumors of childhood outside the central nervous system. The final chapter will describe late effects of childhood cancer and its therapy and the impact research is having on understanding and perhaps preventing these late effects.
