Book Description
Significant changes in diet, environment, and population increase gastrointestinal cancer morbidity. A growing number of novel biomarkers and underlying mechanisms are being elucidated, some of which may even conflict with assumptions of past decades. Therefore, collecting recent findings on novel diagnostic/prognostic factors, biomarkers, and/or risk factors in gastrointestinal cancers is a prerequisite for a better understanding of the disease. Despite remarkable progressions in surgical treatments and chemotherapies, the prognosis of gastrointestinal cancer is far from satisfactory due to the high occurrence of drug resistance. Based on the identification of novel biomarkers as well as their underlying mechanisms, targeted drug development will provide significant complementary therapeutic effects to conventional chemoradiotherapies. High-throughput methods such as next-generation sequencing on RNA level and mass spectrometry on protein/lipid/metabolite level serve as efficient strategies for biomarker identification and drug development. This Research Topic aims at presenting recent advances on gastrointestinal cancer biomarkers and their underlying functional mechanisms, providing a better understanding of carcinogenesis, tumor progression, tumor relapse, as well as drug resistance. This will subsequently contribute to the development of novel therapeutic interventions targeting gastrointestinal cancers, thus improving patients' outcomes.

Book Description
This book describes various novel biomarkers for the early diagnosis of gastrointestinal (GI) cancers. It also highlights recent advances in understanding the role of molecular markers and biomarkers, such as volatile biomarkers, serum biomarkers, predictive and prognostic molecular markers for the early detection of GI cancers. Further, it discusses novel biomarkers, including circulating microRNAs, serum microRNA and plasma microRNA in GI cancer. The book presents breakthrough technologies like ultra-sensitive nano-chips, nanosensors, nanodevices, biosensors, electrochemical biosensors, optical biosensors, DNA biosensors, synthetic biology devices, and 'omics' technologies for the early diagnosis of gastrointestinal cancer. In addition it examines the potential of genome-wide association studies, big data analytics, computation biology, systems biology, and nanotechnology for early diagnostics and therapeutics for gastrointestinal cancer, with a focus on personalized cancer treatment. The book is a valuable source for researchers and clinicians engaged in detection and diagnosis of gastrointestinal cancers.

Book Description
A link between inflammation and cancer has been established many years ago, yet it is only recently that the potential significance of this connection has become apparent. Although several examples of chronic inflammatory conditions, often induced by persistent irritation and/or infection, developing into cancer have been known for some time, there has been a notable resistance to contemplate the possibility that this association may apply in a causative way to other cancers. Examples for such progression from chronic inflammation to cancer are colon carcinoma developing with increased frequency in patients with ulcerative colitis, and the increased incidence of bladder cancer in patients suffering from chronic Schistosoma infection. Inflammation and cancer have been recognized to be linked in another context for many years, i.e., with regards to pathologies resembling chronic lacerations or 'wounds that do not heal.' More recently, the immunology of wound healing has given us clues as to the mechanistic link between inflammation and cancer, in as much as wounds and chronic inflammation turn off local cell-mediated immune responses and switch on growth factor release as well the growth of new blood vessels - angiogenesis. Both of these are features of most types of tumours, which suggest that tumours may require an immunologically shielded milieu and a growth factor-rich environment.

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
Gastrointestinal malignancies encompass a large number of tumor types, and collectively are responsible for a significant portion of new cancer cases annually. According to the IARC database, colorectal cancer alone is responsible for approximately 10% of new cases of cancer worldwide annually. There is significant heterogeneity across the various tumor types, with different pathways and factors involved in oncogenesis, as well as varying degrees of prognosis depending on the tumor type. Non-coding RNAs (ncRNAs) contribute to a significant portion of the human transcriptome, and of particular interest are the micro-RNAs (miRNAs), long ncRNAs (lncRNAs), and circular ncRNAs (circRNAs). With the advent of next-generation sequencing and new technologies such a minimally invasive biopsy techniques, there is a growing body of evidence elucidating the role of ncRNAs in the progression of various form of gastrointestinal cancers. Furthermore, in addition to their relevance to cancer progression, these ncRNAs have important potential as biomarkers and prognostic markers for various GI cancers.
