Gastric cancer represents one of the most frequent and lethal tumors worldwide today, finding itself in the fifth place in incidence and the third in mortality. Surgery remains the only curative treatment for localized tumors, but only 20% of patients are suitable for surgery due to the lack of specific symptoms and the late diagnosis, especially in Western countries. Additionally, even in patients who receive curative treatment, rates of locoregional relapse and distant metastasis remain high. Palliative chemotherapy is the principal treatment in cases of metastatic disease even if the prognosis of patients receiving chemotherapy is still poor. Therefore, a multidisciplinary evaluation is important in order to improve the efficacy of active treatments. In this context, there is an unmet need for a better understanding of genetic alterations and prognostic and predictive factors in order to choose the best tailored therapy for each patient. The aim of this Special Issue is to focus on the results and problems of multimodality treatment in metastatic gastric cancer, the search for prognostic and predictive factors, and the evaluation of novel strategies for individualized treatment. We are inviting relevant original research, systematic reviews, meta-analyses, and short communications covering the above-mentioned topics.

This book highlights the importance of understanding gastric and colon cancer metabolism in guiding diagnosis and drug discovery. It summarizes the correlation between adiponectin and matrix metalloproteinase with colorectal cancer. The book also evaluates the divergent role of hypoxia-inducible factor 1 in colorectal cancer growth and metastasis. After discussing the role of genetic polymorphisms in alcohol metabolizing enzymes and EPHX1 with the onset of colorectal cancer, it reviews the molecular mechanisms of chemoresistance in gastric cancer and novel therapeutic strategies to reverse the chemoresistance of tumors. In addition, the book explores the theranostic role of nanoparticles and therapeutic potential of phytochemicals with regard to colorectal cancer. Given its scope, the book offers a valuable guide for oncologists, academic researchers, pharmaceuticals practitioners, and students who are involved in research and treatment of cancer.

Gastrointestinal (GI) cancer is a major cause of morbidity and mortality in the world. Since early diagnosis and optimal treatment selection are crucial to improving the prognosis of these diseases, the discovery of useful biomarkers has the potential to greatly reduce their burden. Recent technical and mechanical developments have allowed for the detection of tiny differences in various factors modified in physical conditions, which could contribute to the discovery of novel biomarkers for some diseases.In this Special Issue, we aim to focus on novel biomarkers for GI cancers, including esophageal cancer, gastric cancer, colorectal cancer, liver cancer, pancreatic cancer and biliary cancer. In addition, any samples (tissue, blood, urine and feces) are useful as biomarker sources, although body-fluid-based biomarkers are promising as diagnostic biomarkers due to their noninvasiveness. This Special Issue aims to collect novel insights clarifying the current situation and future perspective in this field.

Biogenic amines have been known for some time. These compounds are found in varying concentrations in a wide range of foods (fish, cheese, meat, wine, beer, vegetables, etc.) and their formations are influenced by different factors associated to those foods (composition, additives, ingredients, storage, microorganism, packaging, handing, conservation, etc.). The intake of foods containing high concentrations of biogenic amines can present a health hazard. Additionally, they have been used to establish indexes in various foods in order to signal the degree of freshness and/or deterioration of food. Nowadays, there has been an increase in the number of food poisoning episodes in consumers associated with the presence of these biogenic amines, mainly associated with histamines. Food safety is one of the main concerns of the consumer and safety agencies of different countries (EFSA, FDA, FSCJ, etc.), which have, as one of their main objectives, to control these biogenic amines, principally histamine, to assure a high level of food safety.Therefore, it is necessary to deepen our understanding of the formation, monitoring and reduction of biogenic amines during the development, processing and storage of food, even the effect of biogenic amines in consumers after digestion of foods with different levels of these compounds.With this aim, we are preparing a Special Issue on the topic of ""Biogenic Amines in Food Safety"", and we invite researchers to contribute original and unpublished research articles and reviews articles that involve studies of biogenic amines in food, which can provide an update to our knowledge of these compounds and their impacts on food quality and food safety.
