Gastric adenocarcinoma is the second most common cancer worldwide. It is usually diagnosed at a late stage and prognosis is poor; even with modern diagnostic and treatment methods the 5-year survival is only 10%. Improvements in overall patient survival can only be achieved by earlier diagnosis and by tailored therapeutic strategies based on tumor type, location and stage at presentation. This volume provides a state-of-the-art, integrated diagnostic and therapeutic approach to patient management. The role of the upper GI series, endoscopy, endoscopic ultrasound, MDCT, MRI, and PET/CT in the diagnosis, staging and follow-up of patients with gastric cancer is emphasized. The relative strengths and limitations of these diagnostic examinations will be presented in context with the most recent epidemiologic, pathologic, and therapeutic concepts regarding this tumor. With expert contributions from members of an international multidisciplinary team, this is an invaluable guide to the diagnosis and management of gastric malignancies.
