Radiomics In Gastric Cancer

Gastric cancer (GC) is one of the most common malignancies worldwide. It is particularly challenging due to common detection at the advanced stages of the diseases preventing potential therapeutic and treatment strategies for patients. Common forms of treatment include chemotherapy which has been found to improve the survival rate and overall quality of life for patients with unresectable, locally advanced or at the metastatic stages of the disease. However, chemotherapy has also proven to cause significant side effects in some patients. Lymphatic metastasis has been found to be common in gastric cancer patients. Lymph vascular invasion (LVI) has been identified to be associated to the infiltration of tumor cells in the arteries, veins or lymphatic vessels. This has been identified to prompt local recurrence and the distant metastasis of various tumors. This has led to the LVI status as an independent prognostic factor and studies have found the occurrence of pathological LVI is associated with gastric cancer progression and linked to poor clinical prognosis and low survival rate.

Gastric cancer is still the most common cause of cancer death in the world, although in most countries, with the notable exception of the United States, its incidence is slowly declining. In statistical terms, gastric cancer is therefore the most formidable of cancer types, and its control is a pressing issue. Recent evidence indicates that the conversion of normal cells to so-called "clinical cancer" is the prerequisite for a multistage process which is intimately associated with an accumulation of multiple gene alterations including both oncogenes and tumor-suppressor genes. Gastric cancer is no exception, in that it reveals multiple gene changes whose scenario differs, depending on their occurrence in intestinal-type or diffuse-type gastric cancers. This book was planned for publication by the Japanese Research Society for Gastric Cancer in order to shed light on basic research and clinical practice in gastric cancer. The individual chapters, written by a variety of experts, contain numerous new topics related to all aspects of the disease, including epidemiology, experimental carcinogenesis, pathology, biology, diagnosis, and treatment. It is hoped that this book will be of use in basic research, pathological diagnosis, early detection, and therapy of gastric cancer. We would like to thank the staff of Springer-Verlag Tokyo for the excellent technical production.

Gastric cancer is one of the most common and potentially lethal gastrointestinal malignancy, but it is now at the forefront of modern oncology due to new discoveries. In recent years, the field of gastric cancer has been transformed by many notable developments in both the diagnostic area and the therapeutic strategies. The main aim of the text is to propose a comprehensive, state-of-the art review of this field, and will serve as a valuable resource for oncologists, pathologists, surgeons and researchers with an interest in gastric cancer. The first chapters will review the interplay between pathogens and especially H. pylori, inflammation, genomic instability, and tumorigenesis. Secondly, an exhaustive overview of the diagnosis of gastric cancer from a clinical/endoscopic and pathologic perspectives will be illustrated. Two specific chapters will deal with tissue and serum biomarkers with an important role in diagnosis as well as prognostic and predictive markers of response to specific therapy. A central section of the book will focus on treatment options available today for patients. Surgery is the cornerstone of treatment for gastric cancer; however, the prognosis of patients with locally advanced disease is still poor even after curative resection. Therefore, in order to improve the prognosis of patients, especially with advanced stage, a multimodal strategy is advisable and is thoroughly addressed in the appropriate section. With the advent of next-generation sequencing and new preclinical model technologies, the genomic landscape of gastric cancer has been delineated and molecular characterizations finalized to novel therapeutic targets of each molecular subtype have been identified. These advances are making it feasible to integrate clinical and phenotype-based diagnostic and therapeutic methods and are described in a dedicated section. The text will conclude with chapters focusing on the future direction of gastric cancer research in the precision medicine era: an in-depth analysis of non-coding RNAs and their role in gastric cancer, the impact of immunomodulation/immunotherapy and the perspectives of nano-medicine will be finally proposed to the audience. A brief review of the existing literature addressing the above mentioned topics will be present in each chapter. This text will serve as a useful resource for physicians and researchers dealing with, and interested in, this challenging malignancy. It will provide a concise yet comprehensive summary of the current status of the field that will help guide patient management and stimulate investigative efforts. All chapters will be written by experts in their fields and will include the most up to date scientific and clinical information.

The twenty-first century has seen a breathtaking expansion of statistical methodology, both in scope and in influence. 'Big data', 'data science', and 'machine learning' have become familiar terms in the news, as statistical methods are brought to bear upon the enormous data sets of modern science and commerce. How did we get here? And where are we going? This book takes us on an exhilarating journey through the revolution in data analysis following the introduction of electronic computation in the 1950s. Beginning with classical inferential theories - Bayesian, frequentist, Fisherian - individual chapters take up a series of influential topics: survival analysis, logistic regression, empirical Bayes, the jackknife and bootstrap, random forests, neural networks, Markov chain Monte Carlo, inference after model selection, and dozens more. The distinctly modern approach integrates methodology and algorithms with statistical inference. The book ends with speculation on the future direction of statistics and data science.

Stomach cancer (also called gastric cancer) is the growth of cancer cells in the lining and wall of the stomach. Stomach cancer represents roughly 2 percent (25,500) cases of all new cancer cases yearly in the United States, but it is much more common in Japan, Great Britain, South America, and Iceland. It is associated with high salt in the diet, smoking, and low intake of fruits and vegetables.Infection with H. pylori is the main risk factor in about 80 percent or more of gastric cancers. It is more common in men. A very small percentage of diffuse-type gastric cancers are thought to be genetic. Hereditary Diffuse Gastric Cancer (HDGC) has only recently been identified and research is ongoing, but genetic testing and treatment options are available for families at risk. Metastasis occurs in 80-90 percent of individuals with stomach cancer, with a five year survival rate of 75 percent in those diagnosed in early stages and less than 30 percent of those diagnosed in late stages. This book presents new and important research from around the world.
