Prostate cancer (PCa) is among the most diagnosed cancers in men worldwide as well as one of the most common causes of cancer-related deaths. Despite the advances in treatment, the disease remains associated with poor survival and resistance to cytotoxic and targeted therapies. Therapy Resistance in Prostate Cancer: Mechanisms and Insights highlights the main mechanisms that are responsible for therapy resistance in PCa allowing researchers and clinicians to have a synopsis of current options and new therapies that can be proposed to overcome this resistance. Understanding the mechanisms responsible for chemotherapy resistance helps researchers all over the world to delve deeper into the pathways behind this resistance and potentially discover new therapeutic targets for PCa. Tackles the topic of resistance from a broader perspective, including, but not limited to, the role of the extracellular matrix and cancer stem cells in therapy resistance Creates understanding on how to develop novel therapies that specifically target CSCs to eliminate the regenerating capacity of the tumor and overcome therapy resistance Helps in identifying novel molecular biomarkers and potential therapeutic targets pertaining to the tumor microenvironment to overcome therapy resistance Provides a general view of the main pathways involved in PCa progression that will aid in understanding the mechanisms responsible for chemotherapy resistance

This comprehensive reference expounds the current state of hormone therapy and castration resistance of prostate cancer (PCa). Previously, the incidence of PCa in Asian countries was relatively low, but it has been increasing dramatically in recent years. Although most of the new cases are diagnosed in early stages, a significant proportion of patients receive hormone therapy for metastatic disease or for relapse after local treatment. Thus the situation has gradually changed toward earlier and longer use of hormone therapy. The malignancy finally forms castration-resistant prostate cancer (CRPC) despite the lack of testicular androgen. With advances in understanding of the molecular basis of hormone dependence and CRPC, many new androgen receptor-targeted agents have emerged. During the last decade, much evidence on hormone therapy has been accumulated in Japan. Interestingly, some of these findings are different from those reported from Western countries, suggesting ethnic variation in the outcome of hormone therapy. In the chapters of this book, expert authors provide exhaustive interpretations of the evidence recently reported from Japan and provide important Asian perspectives on hormone therapy for PCa. This work benefits not only Asian urologists but also their Western counterparts and all physicians and medical personnel who are involved in the treatment of PCa.

Nanostructures for Cancer Therapy discusses the available preclinical and clinical nanoparticle technology platforms and their impact on cancer therapy, including current trends and developments in the use of nanostructured materials in chemotherapy and chemotherapeutics. In particular, coverage is given to the applications of gold nanoparticles and quantum dots in cancer therapies. In addition to the multifunctional nanomaterials involved in the treatment of cancer, other topics covered include nanocomposites that can target tumoral cells and the release of antitumoral therapeutic agents. The book is an up-to-date overview that covers the inorganic and organic nanostructures involved in the diagnostics and treatment of cancer. Provides an examination of nanoparticle delivery systems for cancer treatment, illustrating how the use of nanotechnology can help provide more effective chemotherapeutic treatments Examines, in detail, the different types of nanomaterials used in cancer therapy, also explaining the effect of each Provides a cogent overview of recent developments in the use of nanostructured materials in chemotherapeutics, allowing readers to quickly familiarize themselves with this area

Carcinoma of the prostate increasingly dominates the attention of urologists for both scientific and clinical reasons. The search for an explanation and the prediction of the variable behaviour of the malignant prostatic cell continues unabated. The search for more precise tumour staging and more effective treatment is equally vigorous. Editors Andrew Bruce and John Trachtenberg have assembled acknowledged leaders in prostate cancer to present those areas of direct interest to the clinician. There are a number of other topics that might have been considered but most of these, such as experimental tumour models or biochemical factors affecting cell growth, still lack immediate application for the clinician. Carcinoma of the prostate continues to have its highest incidence in the western world, and the difference in comparison with the incidence in the Far East appears to be real and not masked by diagnostic or other factors. A number of other epidemiological aspects need careful analysis: Is the incidence increasing? Is the survival improving? Is the prognosis worse in the younger patient? Epidemiological data are easily misused and misinterpreted so that a precise analysis of the known facts makes an important opening chapter to this book.

In order to better understand the molecular basis for the development of therapeutic resistance by prostate cancer, we have undertaken experimentation in which we genetically compared therapy resistant prostate cancer cells to therapy sensitive prostate cancer cells. As a result of this comparison, we have identified a novel gene product, previously referred to as T6 (now referred to as Protocadherin-PC) that is highly upregulated when prostate cancer cells are selected for resistance to apoptotic agents in vitro and when these cells are selected for hormonal resistance in vivo. This progress report describes our success in characterizing the human Protocadherin-PC gene and gene product and in describing the probable mechanism through which this protein increases therapeutic resistance of prostate cancer cells. As a result of these studies, we believe that prostate cancer progresses to the state of therapeutic resistance in a mechanistically similar manner to that of human colon cancer and melanoma.

Prostate cancer is the most common noncutaneous prostate cancer. Research has revealed several distinct malignancy and the second leading cause of cancer mechanisms of castration-resistant disease that may deaths among men in the United States. It is a critical converge in patients with disease progression on public health problem and remains incurable in the ADT. Many approaches are currently being evaluated metastatic setting with mortality that usually occurs as to improve the treatment of this condition and these a result of castration-resistant disease. fndings have identifed several potential targets for Since Huggins and Hodges’ report of the dra- therapeutic intervention. These include drugs that are matic clinical effects of suppressing serum testos- more active or less toxic chemotherapy agents; drugs terone levels in men with advanced prostate cancer that induce androgen deprivation; drugs that target in 1941, hormone therapy (also called androgen the androgen receptor and/or androgen synthesis; deprivation therapy [ADT]) has become widely drugs that target specifc pathways, including ang- accepted as the mainstay of therapy for the treat- genesis and tyrosine kinase inhibitors, endothelin ment of advanced prostate cancer.

Many of these agents treatment of men with locally advanced prostate seem promising and the rationale and effcacy of cancer on the basis of evidence that shows improved these emerging therapies remain to be validated in survival.
