Gastrointestinal (GI) cancers account for nearly 150,000 deaths each year, in the United States alone. Encouragingly, environmental risk factors, premalignant conditions, and high-risk familial kindreds are well described for many GI cancers. In this comprehensive volume on GI Neoplasia, all luminal cancers will be discussed, along with pancreas cancer, gastrointestinal stromal tumors (GISTs), carcinoid tumors, and neuroendocrine tumors. Hepatobiliary cancers are not addressed, as these tumors could form the basis of a separate volume. Articles are organized to address several key topics for each cancer type, such as: public health burden, molecular pathways, risk and protective factors, early detection, clinical evaluation, management, and survivorship.

In this issue of Diagnosis and Treatment of Gastrointestinal Cancers, guest editors Drs. Marta Davila and Raquel E. Davila bring their considerable expertise to the topic of Diagnosis and Treatment of Gastrointestinal Cancers. The early detection, diagnosis, and accurate staging of GI cancers, along with enhanced imaging techniques, new therapies, and a greater understanding of GI tumors at the molecular level, has revolutionized the approach to GI cancer patients in recent years. In this issue, distinguished authors recognized internationally as leading authorities in the field provide an exhaustive review of the latest topics in GI cancer. Contains 13 practice-oriented topics including management of Barrett’s esophagus and early esophageal adenocarcinoma; familial pancreatic cancer; colorectal cancer: screening and early detection; the microbiome in gastrointestinal cancers; and more. Provides in-depth clinical reviews on diagnosis and treatment of gastrointestinal cancers, offering actionable insights for clinical practice. Presents the latest information on this timely, focused topic under the leadership of experienced editors in the field. Authors synthesize and distill the latest research and practice guidelines to create clinically significant, topic-based reviews.

Gastric cancer is the second most common cause of cancer mortality worldwide. Although the incidence of gastric cancer has declined over the past century in the United States, it remains one of the most common gastrointestinal neoplasms, particularly in immigrants and the socio-economically deprived. Recent years have seen major advances in our understanding of the pathogenesis of gastric cancer (especially regarding the importance of Helicobacter pylori and its associated inflammatory response) and the emergence of adjuvant oncologic therapies of proven benefit for advanced cases, in addition to surgery. As for gastric adenocarcinoma, elucidation of the underlying biology and molecular pathogenesis has led to much progress in the management of two other malignant gastric neoplasms, gastrointestinal stromal tumors and marginal zone B-cell (“MALT ) lymphomas. This monograph highlights these developments, presenting an updated overview of gastric cancer that will be of interest to all practicing gastroenterologists.

In this issue of Gastroenterology Clinics, Guest Editors M. Nedim. N. Ince and David E. Elliott bring their considerable expertise to the topic of Gastrointestinal Infections. Top experts in the field cover key topics such as Candida esophagitis, Acute bacterial gastroenteritis, Clostridium difficile infection and antibiotic-associated diarrhea, and more. - Provides concise and comprehensive coverage of the issues physicians face every day. - Presents the latest information on a timely, focused topic under the leadership of experienced editors in the field. - Contains 14 relevant, practice-oriented topics including Helicobacter pylori infection; Viral gastroenteritis in special patient populations; Rare causes of hepatitis; Postinfectious irritable bowel syndrome; and more.

Dr Roy Soetikno and Dr Tonya Kaltenbach are the editors for this issue of Gastrointestinal Endoscopy Clinics of North America, which is devoted to the improved detection and management of early neoplasia in inflammatory bowel disease. An important aspect of Dr Soetikno’s outstanding career has been the bridging of endoscopic methods between Japan and the United States. Endoscopists in Japan have a better record of detecting subtle flat GI lesions. From the earliest days of endoscopy, it is fair to say that Japanese endoscopists have emphasized visual identification, analysis, and photo documentation of small GI lesions. The colon has been no exception. Dr Soetikno has incorporated these techniques, which have become increasingly feasible with steady improvement in modern digital endoscopes. Identifying small flat premalignant lesions and early cancers in patients with colitis can be lifesaving. Dr Soetikno and Dr Kaltenbach have edited an extraordinary issue of the Gastrointestinal Endoscopy Clinics of North America devoted to teaching and promulgating these methods, including an extensive photo atlas, which should be an invaluable resource for all academic specialists and practicing gastroenterologists.

With collaboration of Consulting Editor, Dr. Alan Buchman, Guest Editors Drs. Gerard Mullen and Berkeley Limketkai have created a practical and current issue covering the breadth of topics in nutrition and gastrointestinal disease. Articles are specifically devoted to the following topics: Nutrition in the Management of Inflammatory Bowel Diseases; Irritable Bowel Syndrome: Food as a Friend or Foe; Treatment of Obesity: Beyond the Diet; Nutritional Management of Acute Pancreatitis; Nutritional Care in Patients with Intestinal Failure; The Life-long Role of Nutrition on the Gut Microbiome and Gastrointestinal Disease; Nutritional Strategies for Esophageal Disorders; Precision Medicine in Obesity; Gastrointestinal Food Allergies and Intolerances; All Things Gluten; Fish Oil for Inflammatory Bowel Disease: Panacea or Placebo; Nutrition Tools for the Practicing Gastroenterologist; Colorectal Cancer and Diet: Is Diet an Intervention; Non-Alcoholic Fatty Liver Disease: Nutritional Considerations; and Nutritional Considerations in the Hospital Setting. Readers will come away with current clinical information that they can employ in the clinical setting to improve outcomes in patients with gastrointestinal diseases.

This issue of Hematology/Oncology Clinics will focus on Upper Gastrointestinal Malignancies; specifically, articles on the following: Epidemiology / Genetics, H. pylori and the gastric microbiome in gastric cancer carcinogenesis; Barrett’s esophagus and esophageal cancer; Tumor Staging; Localized disease; Metastatic Disease; Immunotherapy Antiangiogenic therapy; and many more!

In this issue of Gastroenterology Clinics, guest editor Dr. Robert Odze brings his considerable expertise to the topic of Pathology and Clinical Relevance of Neoplastic Precursor Lesions of the Tubal Gut, Liver, and Pancreaticobiliary System: A Contemporary Update. Top experts review all the basic advances in the biology of neoplastic precursor lesions and its molecular and clinical implications to provide a better and more uniform understanding of mechanisms of cancer development in the gastrointestinal system and related organs. - Contains 10 relevant, practice-oriented topics including Barrett's esophagus and associated dysplasia; hepatic precancerous lesions and early hepatocellular carcinoma; pathology and clinical significance of inflammatory bowel disease-associated colorectal dysplastic lesions; sporadic colorectal polyps of the colon; pathology of gastrointestinal polyposis disorders; and more. - Provides in-depth clinical reviews on neoplastic precursor lesions of the tubal gut, liver, and pancreaticobiliary system, offering actionable insights for clinical practice. - Presents the latest information on this timely, focused topic under the leadership of experienced editors in the field. Authors synthesize and distill the latest research and practice guidelines to create clinically significant, topic-based reviews.

These guest editors have assembled a high-profile group of international authors to present state-of-the-art information on advances in diagnostic modalities for gastrointestinal cancer. Special attention is given to magnification endoscopy and narrow band imaging, confocal endomicroscopy, PET scanning, and single fiber endoscopy. Clinical entities discussed include gastric cancer, biliary cancer, pancreatic cancer, esophageal cancer (Barrett's Esophagus), colorectal cancer, intraductal papillary mucinous neoplasms, as well as gastric tumors.
