Staging of GI Malignancies -- Endoscopic Techniques for GI Maligancies.-Esophagogastric.-��Hepatopancreaticobiliary -- Small Bowel -- Colorectal Cancer -- Neuroendocrine -- Circulating Tumor Cells in Gastrointestinal Malignancy -- Costs and Utilization of Treatments for Advanced Disease -- Survivorship -- Animal models of GI Malignancy -- Ras-Superfamily GTPases in GI Malignancy.

This book comprehensively summarizes the current state of knowledge on malignancies of the gastrointestinal tract. Dedicated organ-based chapters evaluate current treatments and management and provide information on incidence, etiology and biological characteristics. The state of the art in the radiologic and endoscopic staging of gastrointestinal malignancies is described, and guidance is offered on the role of interventional radiology and interventional gastroenterology in the treatment of these challenging tumors. In addition, the book explores novel and evolving treatments, including personalized systemic therapy and minimally invasive surgical and radiology techniques, and addresses patient-reported outcomes and survivorship challenges. It closes by discussing animal models of gastrointestinal malignancies and examining the significance of the Ras superfamily of GTPases. It will be of benefit to all surgeons, oncologists and other specialists who treat these malignancies, as well as to trainees looking to increase their understanding of the field.
