Book Description
Cancer cell biology research in general, and anti-cancer drug development specifically, still relies on standard cell culture techniques that place the cells in an unnatural environment. As a consequence, growing tumor cells in plastic dishes places a selective pressure that substantially alters their original molecular and phenotypic properties.The emerging field of regenerative medicine has developed bioengineered tissue platforms that can better mimic the structure and cellular heterogeneity of in vivo tissue, and are suitable for tumor bioengineering research. Microengineering technologies have resulted in advanced methods for creating and culturing 3-D human tissue. By encapsulating the respective cell type or combining several cell types to form tissues, these model organs can be viable for longer periods of time and are cultured to develop functional properties similar to native tissues. This approach recapitulates the dynamic role of cell–cell, cell–ECM, and mechanical interactions inside the tumor. Further incorporation of cells representative of the tumor stroma, such as endothelial cells (EC) and tumor fibroblasts, can mimic the in vivo tumor microenvironment. Collectively, bioengineered tumors create an important resource for the in vitro study of tumor growth in 3D including tumor biomechanics and the effects of anti-cancer drugs on 3D tumor tissue. These technologies have the potential to overcome current limitations to genetic and histological tumor classification and development of personalized therapies.

Book Description
This book provides a wealth of images and extensive information on circulating tumor cells (CTCs) and other cells usually observed in blood from patients with cancer, such as giant macrophages, and circulating tumor microemboli (CTM). The field of “liquid biopsy” began with the analysis of CTCs in the early 2000s. In the beginning, molecular techniques were developed to detect these cells in the blood. However, it has since become clear that CTCs initially require a cytopathological analysis to be detected without false positive and negative results. After detection, molecular analysis can be subsequently performed. Cancer is an important cause of mortality, especially when detected in late stages. Even with all the advances that have been made in its treatment, cancer is still challenging, as many patients do not respond to any therapy. Many health agencies have considered early diagnosis as a feasible tool. In this context, it is of the utmost importance to know the morphology and characteristics of CTCs to determine a correct diagnosis. Currently much of the scientific community is committed to expanding our knowledge of CTCs, and this work makes a valuable contribution, presenting hundreds of cell images from patients with various types of cancer, in many different stages of disease, and after receiving various treatments. The Atlas of Liquid Biopsy: Circulating Tumor Cells and Other Rare Cells in Cancer Patients’ Blood is an essential reference guide for all physicians, biologists, biomedics, and professionals working at clinical and research laboratories, hospitals and research centers.

Book Description
Expert laboratory and clinical researchers from around the world review how to design and evaluate studies of tumor markers and examine their use in breast cancer patients. The authors cover both the major advances in sophisticated molecular methods and the state-of-the-art in conventional prognostic and predictive indicators. Among the topics discussed are the relevance of rigorous study design and guidelines for the validation studies of new biomarkers, gene expression profiling by tissue microarrays, adjuvant systemic therapy, and the use of estrogen, progesterone, and epidermal growth factor receptors as both prognostic and predictive indicators. Highlights include the evaluation of HER2 and EGFR family members, of p53, and of UPA/PAI-1; the detection of rare cells in blood and marrow; and the detection and analysis of soluble, circulating markers.

Book Description
Drug Resistance in Colorectal Cancer: Molecular Mechanisms and Therapeutic Strategies, Volume Eight, summarizes the molecular mechanisms of drug resistance in colorectal cancer, along with the most up-to-date therapeutic strategies available. The book discusses reasons why colorectal tumors become refractory during the progression of the disease, but also explains how drug resistance occurs during chemotherapy. In addition, users will find the current therapeutic strategies used by clinicians in their practice in treating colorectal cancer. The combination of conventional anticancer drugs with chemotherapy-sensitizing agents plays a pivotal role in improving the outcome of colorectal cancer patients, in particular those with drug-resistant cancer cells. From a clinical point-of-view, the content of this book provides clinicians with updated therapeutic strategies for a better choice of drugs for drug-resistant colorectal cancer patients. It will be a valuable source for cancer researchers, oncologists and several members of biomedical field who are dedicated to better treat patients with colorectal cancer.

Book Description
This volume will outline how to recreate the tumor microenvironment, to culture primary tumors without the need for developmental priming factors, and to deliver targeted therapeutics in a manner that recapitulates pharmacokinetics in vivo. Much of what may be learned from this volume will aid in understanding many aspects of the enhanced study of tumor cell biology in a physiologic context, open new avenues for drug screening and biomarker development, and accelerate the preclinical evaluation of novel personalized medicine strategies for patients in real time.

Book Description
​This book incorporates a multi-disciplinary approach to present how research results can be translated into clinical trials. The first part begins with a chapter on variants of pancreatic cancer, precursor lesions and groups of people at risk to developing the disease. There is a particular focus on intraductal papillary mucinous neoplasia as a large-scale clinical challenge in pancreatology. The next two parts focus on diagnosis, biomarkers and stratification that emphasize how various approaches to biomarker development are important as both prognostic and predictive tools. The final part consists of personalized treatment approaches that include preclinical models of pancreatic cancer and stromal, epigenetic and metabolism targeting as promising approaches to be translated into early phase clinical trials. Chapters within this part also deal with approaches that are close to being implemented in clinical practice or are already being tested in (early) clinical trials, such as those that targeting the immune systems and strategies to overcome immunotherapy resistance; phase 1 clinical trials and translational approaches in surgical treatment. Written by experts in their fields, Translational Pancreatic Cancer Research provides an outlook towards future directions by integrating information both from basic and clinical research and though demonstrating pathways to better understanding pancreatic cancer and current approaches to translating these into clinical practice.

Book Description
The results of randomized trials evaluating the use of early or adjuvant systemic treatment for patients with resectable breast cancer provide an eloquent rebuttal to those who would argue that we have made no progress in the treatment of cancer. Many of the tumors that we have been most successful in curing with chemotherapy and other newer forms of treatment are relatively uncommon. In contrast, breast cancer continues to be the single most common malignancy among women in the western world, is increasingly a cause of death throughout Asia and Third-World countries, and remains one of the most substantial causes of cancer mortality world wide. The use of mammography as a means of early detection has been shown to reduce breast cancer mortality by 25-35% among those popu lations in which it is utilized. The use of adjuvant systemic treatment in appropriate patients provides a similar (and additional) reduction in breast cancer mortality. Few subjects have been so systematically studied in the history of medicine, and it seems fair to conclude that the value to adjuvant systemic therapy in prolonging the lives of women with breast cancer is more firmly supported by empirical evidence than even the more conventional or primary treatments using various combinations ofsurgery and radiotherapy.
