Book Description
Gastrointestinal (GI) malignancies account for a large portion of cancers worldwide. Although incidence of esophageal, gastric, and colorectal cancers has decreased in recent years, pancreatic and liver cancer have increased. The mainstay of GI cancer therapy is chemoradiation and surgery. Despite significant medical advancements, diagnosis and therapy for GI cancers remain challenging due to tumor cell resistance to chemoradiotherapy. The tumor’s increased cell signalling due to excessive transcription factor activation and increased stellate cell activity leads to collagen deposition formation of a dense stroma around the tumor, which prevents drugs from reaching the malignant cells. This leads to tumor chemoresistance. To circumvent these difficulties, drug therapy targeting the tumor’s specific microenvironment and the additive anticancer effect of phytochemicals can allow for more effective treatment. This volume will be the first on the market on the topic of phytochemicals and their effect on the tumor microenvironment (TME). TME is an emerging area of research and the book will be a welcome introductory addition to the field.

Book Description
This Research Topic is part of a series with: Herbal Medicines for Gastrointestinal and Hepatic Diseases - Novel Pharmacological and Toxicological approaches, Volume II Ethnopharmacology deals with the exchange of knowledge about people's use of herbal medicines and their pharmacological effects. The information related to therapeutic agents of plant origin and their toxic effects was preserved by oral tradition as well as recorded in materia medica. Many drugs that are now available on the market have been developed from this valuable information. Today, scientists that specialize in medicinal chemistry use these existing herbal drugs to develop and produce more therapeutically active agents with less toxic side effects. The gastrointestinal tract (GIT) is a multi-organ system, consisting of bacteria, and digestive enzymes that have the capacity of degrading food and other molecules. Diseases associated with this organ system include peptic ulcer, inflammatory bowel disease, gastric cancer to name a few. The liver receives seventy percent of its blood supply from the GIT via the hepatic portal vein. The disruption in the gut–liver axis is associated with liver diseases including alcohol-associated liver disease (ALD), non-alcoholic fatty liver disease (NAFLD), and autoimmune liver disease (AILD). NAFLD can cause non-alcoholic steatohepatitis, which can develop into liver cirrhosis through inflammation and fibrosis. Liver cirrhosis is categorized as an end-stage of chronic liver disease, which impairs innate immunity-related genes. Growing evidence from preclinical studies proposes that the gut–liver axis leads to targeted therapeutic modalities for various liver injuries. Therefore, therapeutic treatment of these conditions is essential to prevent progression to these more harmful late-stage diseases.

Book Description
In this book we provide insights into liver – cancer and immunology. Experts in the field provide an overview over fundamental immunological questions in liver cancer and tumorimmunology, which form the base for immune based approaches in HCC, which gain increasing interest in the community due to first promising results obtained in early clinical trials. Hepatocellular carcinoma (HCC) is the third most common cause of cancer related death in the United States. Treatment options are limited. Viral hepatitis is one of the major risk factors for HCC, which represents a typical “inflammation-induced” cancer. Immune-based treatment approaches have revolutionized oncology in recent years. Various treatment strategies have received FDA approval including dendritic cell vaccination, for prostate cancer as well as immune checkpoint inhibition targeting the CTLA4 or the PD1/PDL1 axis in melanoma, lung, and kidney cancer. Additionally, cell based therapies (adoptive T cell therapy, CAR T cells and TCR transduced T cells) have demonstrated significant efficacy in patients with B cell malignancies and melanoma. Immune checkpoint inhibitors in particular have generated enormous excitement across the entire field of oncology, providing a significant benefit to a minority of patients.

Book Description
The medicinal uses of Curcumin (also called turmeric) have been known and described for more than 5000 years. A large body of recent research suggests that curcumin is potentially useful in the treatment of inflammatory diseases, through modulation of numerous molecular targets. This is the first monograph to focus on the potential use of curcumin in the treatment of cancer, diabetes, cardiovascular diseases, arthritis, Alzheimer’s, psoriasis and more.

Book Description
Gastrointestinal (GI) cancers, including gastric cancer, colon cancer, liver cancer, esophageal cancer, and pancreatic cancer, seriously threaten the health of human beings worldwide with a high rate of morbidity and mortality. The clinical successes achieved with immune checkpoint inhibitors (ICIs) targeting PD-1/PD-L1 and CTLA-4 have opened a new cancer therapy era and brought new hope to cancer patients. However, the overall response rate (ORR) of ICI monotherapy in the non-selective population is only about 20%, in which some patients subsequently develop immunotherapy resistance. Moreover, the remaining 70-80% of patients displayed primary resistance to ICIs, and a few patients even experienced hyper progression disease (HPD). Although PD-L1 expression, mismatch repair deficient (MMRd), high tumor mutational burden (TMB-H) , high homologous recombination deficiency (HRD), and tumor infiltrated immune cells (TILs) are known as effective biomarkers for immunotherapy, growing studies have reported that ICIs could not improve the OS of all patients with PD-L1 expression higher than 50%, and the ORR of MSI-H patients was only about 60%, whereas some patients with low PD-L1 expression or MSS could still benefit from immunotherapy, indicating the complexity of ICI resistance. Therefore, it is of great importance and significance to explore the prediction biomarkers for primary or acquired immunotherapy resistance and elucidate their underlying molecular mechanisms and develop reversal strategies. Due to the multiple steps of the cancer immune cycle and complex immune microenvironment, any disorders of immune cell infiltration or T cell activation, such as lack of antigens and/or their presentation, lack of response to antigen presentation, and T cell priming, could contribute to ICI resistance. The combination with anti-angiogenesis therapy, radiotherapy, chemotherapy, and other ICIs has improved the efficacy of ICI therapy to some extent in the clinic. Although numerous studies related to ICI resistance were reported in GI cancers, due to the strong spatial/temporal heterogeneity and the complex immune microenvironment in different kinds of GI cancers and different individuals, many questions about ICI resistance and reversal strategies remain unsolved. The aim of this Research Topic is to provide a forum to exhibit the latest research achievement related to the exploration of biomarkers for immunotherapy resistance including HPD and the underlying molecular mechanisms, as well as the development of reversal strategies in GI cancers. We hope this Research Topic will lead to a better understanding of precision cancer immunotherapy and provide useful clues for clinical application to benefit more GI cancer patients with immunotherapy.
