This publication brings together leading experts in the fields of basic research and clinical management of gastric cancer, to share their expertise with the clinical community. State-of-the-art reviews discuss the pathogenesis of and the most important risk factors for the development of gastric cancer, potential benefits of chemoprevention and Helicobacter pylori eradication. Moreover, new diagnostic modalities and surgical therapy, including the potential benefits of neoadjuvant and adjuvant therapies, are presented.
