Strategies for Overcoming Chemotherapy Resistance in Cervical Cancer: From Molecular Insights to Precision Solutions, Volume 21 highlights different strategies to reverse chemotherapy resistance in cervical cancer. The book puts a strong focus on strategies to reverse chemotherapy resistance as well as strategies for early detection of the resistance, enhancing precision oncology in terms of patient care and maximizing patient management. The book also looks at virally induced resistance to chemotherapy and recommends combination therapies that can maximize the reversal of this resistance.In 10 chapters, the book not only gives an overview of cervical cancer and chemotherapy as treatment, but also investigates resistance to chemotherapy and treatment for resistance. It defines treatment mechanisms, options, and limitations to beat chemotherapy resistance and the reversal of the resistance mechanisms. It gives insights into future directions of cervical cancer treatment using epigenetic silencing, chemotherapy splicing, the involvement of MicroRNAs to chemotherapy resistance, and the application of Artificial Intelligence. - Discusses strategies to reverse and detect resistance to chemotherapy at an early stage - Investigates the applications of Artificial Intelligence in the study of cervical chemotherapy resistance - Presents research and applications developed to overcome cancer resistance

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.

Leading experts summarize and synthesize the latest discoveries concerning the changes that occur in tumor cells as they develop resistance to anticancer drugs, and suggest new approaches to preventing and overcoming it. The authors review physiological resistance based upon tumor architecture, cellular resistance based on drug transport, epigenetic changes that neutralize or bypass drug cytotoxicity, and genetic changes that alter drug target molecules by decreasing or eliminating drug binding and efficacy. Highlights include new insights into resistance to antiangiogenic therapies, oncogenes and tumor suppressor genes in therapeutic resistance, cancer stem cells, and the development of more effective therapies. There are also new findings on tumor immune escape mechanisms, gene amplification in drug resistance, the molecular determinants of multidrug resistance, and resistance to taxanes and Herceptin.

Phytochemicals and derivatives have become promising alternatives to increase treatment potential in cancer patients with minimal side effects. Drug-delivery Systems of Phytochemicals as Therapeutic Strategies in Cancer Therapy elucidates the importance of various phytochemicals in cancer therapy and explains various routes/methods to deliver phytochemicals for overcoming the problems associated with delivery system in cancer treatment. Several nanotechnological methods are followed to enhance drug solubility, sustainability, bioavailability and gastrointestinal permeability of these phytochemicals. The advanced field of drug-delivery systems explains that combination therapy for cancer treatment has important benefits over mono-delivery therapeutics. Natural compounds, because of their biobased origin, have drawn higher attention than synthetic drugs. Synthesis of nano-phytomedicines has impacted the bioavailability of phytochemicals. Novel formulations have been synthesized loaded with phytochemicals and have revealed extraordinary results in treatment of various cancers.
