Evolution of the Molecular Biology of Brain Tumors and the Therapeutic Implications


Book Description

A dramatic increase in knowledge regarding the molecular biology of brain tumors has been established over the past few years. In particular recent new avenues regarding the role of stem cells and microRNAs along with further understanding of the importance of angiogenesis, immunotherapy and explanations for the resistance of the tumors to chemotherapeutic agents and radiation therapy has been developed. It is hopeful that this new information will lead to efficacious treatment strategies for these tumors which remain a challenge. In this book a review of the latest information on these topics along with a variety of new therapeutic treatment strategies with an emphasis on molecular targeted therapies is provided.




Genomics and Models of Nerve Sheath Tumors


Book Description

Nerve sheath tumors can be a significant cause of morbidity for many patients. These include benign tumors such as schwannomas, diffuse and plexiform neurofibromas, and atypical neurofibromas, as well as the aggressive soft tissue sarcoma known as the malignant peripheral nerve sheath tumor (MPNST). Nerve sheath tumors occur sporadically and in the context of the clinical neuro-genetic tumor predisposition syndromes neurofibromatosis type 1 (NF1) and type 2 (NF2). Historically, the mainstay of treatment for nerve sheath tumors has been surgery. However, for both benign and malignant nerve sheath tumors, there is a high recurrence rate, highlighting the pressing need for novel therapies. As we have entered the genomic era, the hope is that an improved understanding of the genetics, and therefore the biology, of these tumors will ultimately lead to therapies that result in better outcomes. In this Special Issue, we include both review articles and original research related to the genomic understanding and modeling of schwannomas, plexiform and diffuse neurofibromas, atypical neurofibromas, and malignant peripheral nerve sheath tumors as well as genomic methods being developed and applied to advance our understanding of these tumors.

A collection of relevant papers in the rapidly expanding field of brain tumor molecular genetics broadens our knowledge about the biology of brain tumors, and inspires further studies that will improve the diagnosis and clinical management of brain tumors. Due to the great heterogeneity of brain tumors it is important to research and understand every aspect of their initiation, progression and metastasis in order to design better diagnostic and therapeutic approaches for their clinical management and patient benefit.




Neurofibromatosis Type 1


Book Description

Neurofibromatosis type 1 (NF1), caused by mutational inactivation of the NF1 tumour suppressor gene, is one of the most common dominantly inherited human disorders, affecting 1 in 3000 individuals worldwide. This book presents in concise fashion, but as comprehensively as possible, our current state of knowledge on the molecular genetics, molecular biology and cellular biology of this tumour predisposition syndrome. Written by internationally recognized experts in the field, the 44 chapters that constitute this edited volume provide the reader with a broad overview of the clinical features of the disease, the structure and expression of the NF1 gene, its germ line and somatic mutational spectra and genotype-phenotype relationships, the structure and function of its protein product (neurofibromin), NF1 modifying loci, the molecular pathology of NF1-associated tumours, animal models of the disease, psycho-social aspects and future prospects for therapeutic treatment.







Evolution by Tumor Neofunctionalization


Book Description

Evolution by Tumor Neofunctionalization explores the possibility of the positive role of tumors in evolution of multicellular organisms. This unique perspective goes beyond recent publications on how evolution may influence tumors, to consider the possible role of tumors in evolution. Widespread in nature tumors represent a much broader category than malignant tumors only. The majority of tumors in humans and other animals may never undergo malignant transformation. Tumors may differentiate with the loss of malignancy, and malignant tumors may spontaneously regress. Cellular oncogenes and tumor suppressor genes play roles in normal development. Many features of tumors could be used in evolution, and there are examples of tumors that have played a role in evolution. This book will stimulate thinking on this topic by specialists in the fields of evolutionary biology, oncology, molecular biology, molecular evolution, embryology, evo-devo, tumor immunology, pathology and clinical oncology. - Covers the role that tumors might play in evolution. - Provides multidisciplinary approach that will appeal to a wide circle of professionals in the fields of evolutionary biology, oncology, molecular biology, and more




Brain Tumor Invasion


Book Description

Brain Tumor Invasion Biological, Clinical, and Therapeutic Considerations Edited by Tom Mikkelsen Rolf Bjerkvig Ole Didrik Laerum Mark L. Rosenblum Recent advances in molecular biology have given us profound new insights into the behavior of primary brain tumors. Not only are such tumors more diffuse in their infiltration of brain tissue and therefore less amenable to surgery than brain tumors originating elsewhere in the body—it now appears that the central nervous system and the normal brain itself constitute a biological environment conducive to the uncontrolled spread of primary tumors. Brain Tumor Invasion is the first comprehensive reference devoted to the invasive behavior of primary brain tumors. It examines the biological mechanisms responsible for the increased ability of gliomas to metastasize in the central nervous system, and discusses the role of chemical carcinogens, growth factors, oncogenes, and tumor suppressors in the progression of such metastases. This book surveys the latest research in the field, reviews present and future prospects of anti-invasive brain tumor therapy, and even translates preclinical trials and other research results into potential new therapies. The material is divided into five main categories: Developmental biology and molecular neuro-oncology Pathological and clinical features of malignant brain tumors Models for the study of brain tumor invasion in vivo and in vitro Mechanisms of invasion New therapeutic strategies Brain Tumor Invasion offers dozens of maps and photographs that illustrate topics under discussion. This in-depth introduction to one of the most difficult problems in the management of brain tumors is indispensable to neuro-oncologists involved in brain tumor research and therapy. It is also useful to researchers in cancer biology, neuroscience, cell biology, and molecular genetics.







Fast Facts: Glioblastoma


Book Description

Glioblastoma (also known as glioblastoma multiforme) is a malignant intrinsic tumor thought to arise from populations of stem/progenitor cells in the brain. It is the most common aggressive intrinsic brain tumor in adults, with the potential to spread rapidly within the brain. Patients with glioblastoma face a poor prognosis, with median overall survival of approximately 15 months. However, our growing understanding of the molecular biology of gliomas means that this outlook may be improving. The identification of clinically relevant subgroups defined by specific genetic mutations is challenging the traditional delineation between low- and high-grade gliomas that has been based on histological appearance and imaging. Indeed, it is becoming clear that, as a molecular entity, a glioblastoma, which by traditional classification is a grade IV glioma, may present with a lower grade initially and then become more aggressive – an important addition to the established concept. The care of a patient with a glioblastoma requires a coordinated approach delivered by a multidisciplinary team, with the aim of maintaining quality of life for as long as possible. Here, we provide a concise overview of the diagnosis and management of glioblastoma, as well as discussion of our emerging understanding of the molecular drivers that are helping us to delineate different patient subgroups. These subgroups will, hopefully, allow more targeted treatments in the future. This resource will be of interest to all those involved in caring for patients with this aggressive brain tumor, including neurologists, neurosurgeons, neuro-oncologists, radiation oncologists, palliative care specialists, specialist nurses and medical students. Contents: • Epidemiology, pathophysiology and classification • Clinical presentation • Diagnosis • Management • Treatment of associated conditions • Emerging research and treatment
