The contents of this book will be organized into three sections. The first section defines the scope, impact and behaviour of cancer regimen-related toxicities and frames the issue of balancing treatment success and physiological cost. In the second segment of the book, the most current thinking around the pathobiology of specific, common, and representative toxicities is presented by leading researchers and translational scientists. The final portion of the book discusses the common biological relationships between toxicities, bioinformatical approaches to analysing key and common pathways, and strategies for the development of effective interventions.
