Book Description
Currently, the treatment options for gastrointestinal malignancies mainly include surgery, chemotherapy, radiotherapy, and molecular targeted therapy, etc. Drug therapy is one of the main treatments for patients with advanced stages, but the efficacy of chemotherapy seems to have reached a plateau, and the progress of traditional molecular targeted therapy is relatively slow. In addition, the benefits of the current chemotherapy combined with targeted therapy for patients with advanced stages of gastrointestinal malignancies are still not satisfactory. Tumor immunotherapy is an emerging therapeutic approach and is a current research hotspot, and there are hopes that immunotherapy can help further improve the prognosis and quality of life for patients with gastrointestinal malignancies. At the same time, potential targets of immunotherapeutic drugs and prognostic biomarkers for gastrointestinal malignancies have been less studied than other common cancers, such as lung cancer. Prognostic biomarker studies are the beginning of exploring new drug targets and revealing potential mechanisms of tumor progression. Immunotherapies, particularly PD1 or PD-L1 antagonists, have demonstrated effective therapeutic efficacy against various types of cancer. To date, many PD1 drugs are available for cancer treatment, and more than 100 PD1 drugs are in clinical trials. However, the question of how to screen sensitive patients and predict the efficacy of immunotherapy remains unresolved. In addition, predictive biomarkers and treatment guidelines for immunotherapy of gastrointestinal malignancies have hardly been studied.

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.

Book Description
This book provides an overview of the available evidence surrounding immunotherapy in gastrointestinal cancers, and discusses its future place in clinical practice. Immunotherapy has celebrated some astonishing therapeutic successes in a variety of cancer types and is becoming increasingly relevant in daily clinical practice. Currently, the predominant class of immunotherapeutic drugs is the so-called checkpoint inhibitors, which disengage the physiological brakes on the immune system, enabling a more effective anti-cancer immune response. Malignancies of the gastrointestinal tract, which account for the majority of cancer cases worldwide, are a major cause of morbidity and mortality, creating an urgent need for more effective therapies. A large number of clinical trials have evaluated the efficacy of cancer immunotherapy in gastrointestinal malignancies and demonstrated its potential in certain subsets of patients. This book will appeal to a wide readership, including oncologists, health care professionals in general and biomedical scientists.

Book Description
This book is about the manipulation of the immune system as a therapeutic approach to gastrointestinal cancer and its clinical applications, exploring therapeutic approaches which might be taken under the broad banner of immunotherapy. Starting by introducing concepts of modern immunology, the clinical applications of immunotherapy are then discussed. The reader will learn about the three broad classes of immune therapeutic agents: cell-based treatment; antibody therapy; cytokine application and the key effector cells and mechanisms which might cause tumour rejection. The reverse side of this equation, the genetic and molecular mechanisms which the tumour can use to escape immune control and regulation, is also discussed. Through reviewing the most up-to-date evidence, this volume provides an overview of the important scientific lessons learned from past failure of immunotherapeutics in the clinic and highlights more positive recent data, coupled to practical guidelines for clinical usage. Written by a team of worldwide experts, this is an indispensable guide for medical oncologists, surgical oncologists, radiation therapists, pharmacists, oncology nurse specialists.

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
Cancer is the second leading cause of death among adults in the United States after heart disease. However, improvements in cancer treatment and earlier detection are leading to growing numbers of cancer survivors. As the number of cancer survivors grows, there is increased interest in how cancer and its treatments may affect a person's ability to work, whether the person has maintained employment throughout the treatment or is returning to work at a previous, current, or new place of employment. Cancer-related impairments and resulting functional limitations may or may not lead to disability as defined by the U.S. Social Security Administration (SSA), however, adults surviving cancer who are unable to work because of cancer-related impairments and functional limitations may apply for disability benefits from SSA. At the request of SSA, Diagnosing and Treating Adult Cancers and Associated Impairments provides background information on breast cancer, lung cancer, and selected other cancers to assist SSA in its review of the listing of impairments for disability assessments. This report addresses several specific topics, including determining the latest standards of care as well as new technologies for understanding disease processes, treatment modalities, and the effect of cancer on a person's health and functioning, in order to inform SSA's evaluation of disability claims for adults with cancer.

Book Description
The field of immuno-oncology continues to rapidly evolve as new insights to fight and treat cancer emerge. The fourth edition of Immunotherapy provides the most current overview of immuno-oncology in different cancer types and toxicities associated with immunotherapy. While immunotherapy has revolutionized the treatment landscape of several solid malignancies, several challenges still exist. Only a subset of patients derive clinical benefits; some do not respond at all, and others respond initially, only for their disease to progress later. Because these drugs can activate a broad range of immune cells, patients suffer from a unique set of side effects known as immune-related adverse events. As more immunotherapeutic agents are used in the clinic, it is important to provide updates about current and ongoing developments in the field to further research efforts and inform treatment decisions. The fourth edition will have a new focus on strategies to overcome the challenges associated with immunotherapy. Chapters will discuss topics such as biomarkers of response, resistance mechanisms, role of imaging in predicting immune-related adverse events, and management of immune-related adverse events. Written by leading experts conducting cutting-edge research, readers will gain up-to-date knowledge on the current state and future of immunotherapy.
