Download or read book Betel quid and Areca nut Chewing and Some Areca nut derived Nitrosamines written by IARC Working Group on the Evaluation of Carcinogenic Risks to Humans and published by IARC. This book was released on 2004 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: A working group of sixteen experts from seven countries re-evaluated the evidence of the carcinogenicity of betel-quid and areca-nut chewing and some areca-nut related nitrosamines. Betel-quid and areca-nut chewing are widely practised in many parts of Asia and in Asian-migrant communities elsewhere in the world. There are hundreds of millions of users worldwide. They evaluated betel quid with tobacco as carcinogenic to humans (Group 1) on the basis of sufficient evidence of an increased risk of cancer of the oral cavity, pharynx and oesophagus. The working group reviewed epidemiological studies of human cancer, mainly studies from India, Pakistan and Taiwan (China). Studies on betel quid with tobacco and areca nut with tobacco in experimental animals now also provide sufficient evidence of carcinogenicity. The working group also evaluated betel quid without tobacco as carcinogenic to humans (Group 1), on the basis of sufficient evidence of an increased risk of oral cancer. Studies on betel quid without tobacco and areca nut without tobacco in experimental animals now also provide sufficient evidence of carcinogenicity. Areca nut, a common ingredient of betel quid and many different chewing preparations, including those available commercially, has been observed to cause oral submucous fibrosis

Download or read book Molecular Determinants of Head and Neck Cancer written by Barbara Burtness and published by Springer. This book was released on 2018-08-03 with total page 628 pages. Available in PDF, EPUB and Kindle. Book excerpt: Squamous cell cancers of the head and neck (SCCHN), also known as head and neck cancers (HNC) encompass malignancies of the oral cavity, larynx, nasopharynx and pharynx, and are diagnosed in over 500,000 patients worldwide each year, accounting for 5% of all malignancies. It is estimated that approximately 50,000 patients develop head and neck cancer annually in the United States, of whom approximately 50% succumb to this cancer. For most cases of SCCHN, treatment is multimodal, often combining surgery or irradiation with chemotherapy; even successfully treated patients frequently experience durable and severe side effects. Improving cure rates and reducing chronic morbidity are urgent clinical needs for head and neck cancer. However, in contrast to cancer types such as breast or prostate that have been much studied and have well-defined biology, until recently, relatively few researchers investigated the molecular basis of HNC, making it difficult to design targeted treatments with better efficacy and less debilitating side effects. This volume will provide an overview of the factors contributing to disease pathogenesis, including the recognition of discrete molecular subtypes with distinct etiology, prognosis, and treatment response. This volume will familiarize the reader with the critical signaling pathways and oncogenic drivers for HNC. It will outline the differences between HPV-positive and HPV-negative disease, and how these differences affect treatment choice and outcome. The book will emphasize developments in the past five years, including the growing understanding of the genomic and epigenomic features of the disease based on analysis of next generation sequencing (NGS) data, and timely topics such as the analysis of HNC stem cell populations, non-coding mRNAs, and inflammatory response. It will address exciting new therapeutic approaches such as the use of immunotherapies to treat HNC patients. Overall, the book will provide the reader with current understanding of the biology and treatment of the disease, and describe timely questions that will guide future research aimed at controlling and curing this disease.
Download or read book Current Research in Head and Neck Cancer written by Henning Bier and published by Karger Medical and Scientific Publishers. This book was released on 2005-01-01 with total page 215 pages. Available in PDF, EPUB and Kindle. Book excerpt: The development of head and neck cancer is a multistep process in which genetic as well as epigenetic alterations interfere with the regular functions of proto-oncogenes and tumor suppressor genes. In addition, carcinogenesis is promoted by the impairment of mechanisms responsible for the maintenance of genetic stability. The accumulation of crucial events such as evasion of apoptosis, lack of senescence, deregulated proliferation, invasion and metastasis, as well as neoangiogenesis eventually determines the malignant phenotype. The 16 articles of this volume span from advances in the understanding of underlying molecular pathways (conditional mouse model, folate activity, DNA repair, genomic heterogeneity, p53 family members, human papillomavirus), to preclinical and clinical studies investigating potential novel therapeutic targets (epidermal growth factor receptor, nuclear factor-kappaB, vascular endothelial growth factor, chemokine receptors, P53-based immunotherapy, virus-modified tumor vaccination), and biometric considerations on the evaluation of prognostic factors. This state-of-the-art publication is recommended reading not only for ENT specialists and oncologists, but also for molecular biologists and other subspecialists interested in head and neck cancer research.

Download or read book Histological Typing of Cancer and Precancer of the Oral Mucosa written by J.J. Pindborg and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 115 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book includes more clinical aspects and concentrates on cancer and precancer of the oral mucosa rather than attempting to cover all benign and malignant tumours of the oral and oropharyngeal tissue. One main emphasis is the significance of the clinical features of the various lesions discussed. Attention is also drawn to those conditions particular to the oral mucosa that may give rise to appearances which are important in differential diagnoses but can be misleading to those who do not have detailed knowledge of the tissue involved. The TNM-classification for malignant tumours of the lip and oral cavity is also included.
Download or read book The Molecular Characterization of Head and Neck Cancer in Young Patients written by Jerry Machado and published by . This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Head and neck squamous cell carcinomas (HNSCCs) most commonly develop in older patients (≥60 years of age) with a history of tobacco and alcohol use. However, young individuals (≤45 years of age) can also develop HNSCC, often without common risk factors. Increasing evidence shows that Human Papillomavirus (HPV) infection is associated with particular HNSCC sites (e.g. oropharynx). We assessed the Roche Linear Array HPV Genotyping Test in several lesions and then examined the prevalence of HPV in HNSCCs from young and older patients. HPV infection was most prevalent in oropharyngeal cancers (16/22, 73%), rarely found in oral cavity cancers (2/53, 4%), and other head and neck sites (1/17, 6%). HPV positive tumors were associated with patients that were >40 and 60 years old (p=0.02). The absence or shortened time of carcinogen exposure from common risk factors and the development of oral squamous cell carcinoma (OSCC) at an early age suggest aberrant genetic events that are different than those in OSSCs from older patients. We used Affymetrix SNP 6.0 arrays to genomically profile oral tumors from young and older patients. Tumors from young patients showed different regions/genes of copy number alterations than those from older patient tumors. An increase of regions of loss of heterozygosity (LOH) in tumors from older patients was observed, and there was a high prevalence of copy number neutral LOH on chromosome 9 in tumors from young and older patients. These data suggest different genetic mechanisms in these patient groups. We have previously shown that HNSCCs from younger patients exhibited a high incidence of microsatellite instability (MSI), a marker of defective mismatch repair (MMR). Deregulated mRNA levels of hPMS1, hPMS2 and hMLH1 were observed and absent/low expression of hPMS1, hPMS2 and hMLH1 protein levels were observed in 50% of OSCCs. No mutations were observed in hPMS1 and hPMS2 and no significant differences of MSI or LOH were observed across genomic loci between tumors of young and older patients. The role of these genetic mechanisms in oral cancer appears complex; studies such as ours should further improve our knowledge of the molecular mechanisms leading to early-onset oral carcinomas.

Download or read book Signaling Pathways in Squamous Cancer written by Adam B. Glick and published by Springer Science & Business Media. This book was released on 2010-11-25 with total page 471 pages. Available in PDF, EPUB and Kindle. Book excerpt: Squamous epithelia form the lining surface of tissues in contact with the environment: the skin, oral mucosa, esophagus and respiratory tract, the genital tract, and several other specialized tissues. These tissues are at highest risk for exposure to environmental carcinogens such as UV, tobacco smoke and infectious agents. Cancers that form in squamous epithelia are among the most common human solid tumors and have high morbidity and mortality. These cancers include squamous cell carcinoma of the skin, oral cancer, head and neck and esophageal cancer, certain lung cancers and cervical cancer. We propose to organize the book so that the early chapters will focus on individual pathways and more specific mechanisms in both normal function and cancer, while the later chapters will be more integrative and include overviews of biomarkers and therapeutic development. This should increase interest for clinically oriented researchers. All authors will be encouraged to provide a balanced review in addition to highlighting their own work.

Download or read book Non melanoma Skin Cancer of the Head and Neck written by Faruque Riffat and published by Springer. This book was released on 2015-09-30 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: Non-melanoma skin cancer is a global public health issue. With an ever-increasing, and ageing, world population coupled with increasing numbers of immunosuppressed individuals the number of patients continues to rise. The head and neck is overwhelmingly the most frequent location for the development of a non-melanoma skin cancer and as such challenges the clinician with its complex anatomy. The importance of maintaining the aesthetics of the face and the function of the anatomy cannot be overstated, yet ultimately it is always the aim of curing a patient with the minimum of morbidity that clinicians strive for. However, the spectrum of presentations and subsequent management varies widely, ranging from patients with the ubiquitous low-risk mid-face basal cell carcinoma to those diagnosed with relatively uncommon but potentially life-threatening high-risk squamous cell carcinomas (e.g. involving metastatic lymph nodes or with perineural invasion present) and Merkel cell carcinomas.
Download or read book Squamous cell Carcinoma written by Saman Warnakulasuriya and published by Springer. This book was released on 2017-03-27 with total page 285 pages. Available in PDF, EPUB and Kindle. Book excerpt: This edited volume is about novel targeted therapies for the treatment of advanced neoplasms of the head and neck (HNSCC) with particular reference to oral squamous cell carcinomas and covers specific fields of cancer genetics and genomics for personalized medicine. The landmark studies from the HNSCC Cancer Genome Anatomy (TCGA) and the cancer Genome Atlas 2015 have revealed the multiplicity and diversity of genetic alterations in HNSCC. This remarkable body of information has elucidated novel druggable targets (eg. EGFR, mTOR, p53, survivin and aberrant microRNA) for therapeutic interventions in head and neck cancer. Readers will discover the importance of the biology and pathology of squamous cell carcinomas, the role of cancer stem cells and other factors that contribute to resistance to curative therapies such as hypoxia. We present an in-depth analysis of the HNSCC oncogenome describing the distinct molecular alterations in squamous cell carcinomas, which participate in specific molecular pathways whose dysregulation may contribute to most HNSCC cases. Final chapters of the book elucidate how these important cancer-driving molecular events and molecular pathways could be targeted to treat head and neck cancers and their therapeutic applications for targeted therapies based on clinical trials reported worldwide. This book is aimed at a broad audience, including scientists, physicians, surgeons, and post graduate students engaged in oncology and provide the readers with an up-to-date, interdisciplinary knowledge and tools to better understand the evolving areas of targeted gene therapy and the key concept of personalized medicine in head and neck cancer.

Download or read book How Tobacco Smoke Causes Disease written by United States. Public Health Service. Office of the Surgeon General and published by . This book was released on 2010 with total page 728 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report considers the biological and behavioral mechanisms that may underlie the pathogenicity of tobacco smoke. Many Surgeon General's reports have considered research findings on mechanisms in assessing the biological plausibility of associations observed in epidemiologic studies. Mechanisms of disease are important because they may provide plausibility, which is one of the guideline criteria for assessing evidence on causation. This report specifically reviews the evidence on the potential mechanisms by which smoking causes diseases and considers whether a mechanism is likely to be operative in the production of human disease by tobacco smoke. This evidence is relevant to understanding how smoking causes disease, to identifying those who may be particularly susceptible, and to assessing the potential risks of tobacco products.
