This volume contains the majority of the invited keynote lectures presented by experts at the Third International Conference on Controversies in Tumor Prevention and Genetics on 12-14 February 2004 in St.Gallen, Switzerland. Together, they reveal the latest findings in oncogenetics and its relations to recent and future developments in primary and secondary tumor prevention, especially in breast, colon and lung cancer. All contributions are written and have been critically reviewed by internationally recognised leaders in the field.
It has been recognized for almost 200 years that certain families seem to inherit cancer. It is only in the past decade, however, that molecular genetics and epidemiology have combined to define the role of inheritance in cancer more clearly, and to identify some of the genes involved. The causative genes can be tracked through cancer-prone families via genetic linkage and positional cloning. Several of the genes discovered have subsequently been proved to play critical roles in normal growth and development. There are also implications for the families themselves in terms of genetic testing with its attendant dilemmas, if it is not clear that useful action will result. The chapters in The Genetics of Cancer illustrate what has already been achieved and take a critical look at the future directions of this research and its potential clinical applications.
Hans-Jorg Senn H.-J. Senn (~) Center for Tumor Detection and Prevention, Rorschacherstr. 150, CH-9006 St. Gallen, Switzerland Clinical oncology has centered mainly on developing new strategies and a multitude of new drugs for fighting relapsing and progressive cancer during the last two decades. Furthermore, it has done this with respectable success in quite a number of neoplastic diseases such as acute leukemias and sarcomas in pediatric patients and certain types of aggressive lymphomas, as well as se lected solid tumors such as testicular cancer and choriocarcinoma in adult age. Curatively intended adjuvant chemo-and endocrine-therapies of several "main killers" among prevalent cancer types, especially breast and colon can cer, have also become successful and health-politically meaningful therapeutic targets [1, 2]. However, the net gain in "cure" of these (mostly pharmacologic) therapeu tic approaches has to be realistically judged as having a moderate impact on the cancer problem as a whole, and the mortality rate of the most frequent tu mor types, which are prevalent in adult life, has with very few exceptions not been substantially decreased over the past two to three decades. Increasingly, health politicians, epidemiologists, and medical journal editors are asking for alternative strategies of lowering cancer incidence and increasing survival, ventilating new and hitherto mostly neglected areas of research such as pri mary and secondary cancer prevention.
The book discusses cancer and the potential use of phytochemicals as cancer therapeutics. It begins with the basics of cancer, including the definition, types, etiology and molecular mechanisms involved, before discussing the fundamentals of diagnosis, treatment and associated problems as well as remedial measures. Since cancer is not a single disease, and the mechanisms of carcinogenesis are different for different cancers, it examines the genes and proteins involved in carcinogenesis, and signal transduction pathways for each individual cancer type. Further, the book reviews the latest research on phytochemicals for cancer treatment, highlighting their anti-cancer properties, sources, structure, active biomolecules and probable mechanisms of action, and describing their biochemical properties in the context of cancer prevention and treatment.
This book presents the latest research on advances in genetics, molecular medicine, biotechnologies, and behavioural sciences that have an impact on primary, secondary and tertiary cancer prevention including: (a) Basic mechanisms of neoplastic diseases leading to the identification of molecular pathways that can be employed as targets for cancer prevention; (b) Descriptive, analytical, and molecular epidemiology with emphasis on developing biomarkers of cancer risk assessment and response to cancer prevention; (c) Laboratory and clinical procedures for prognostic evaluation of malignant tumour transformation, progression and response to treatment with cancer preventive agents; (d) Discoveries of natural substances and synthetic agents that have promising cancer preventive potential and elucidating their mechanistic action; (e) Development and assessment of cancer preventive approaches that have potential for being translated into the clinic; (f) Cancer prevention pre-clinical studies and clinical trials; (g) Patient management and education, management of curable lesions, education and lifestyle modification and the role of behavioural factors in cancer etiology and prevention.
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.
Uniquely designed for oncologists and general practitioners, this book offers clinicians comprehensive guidelines when dealing with women at high risk for breast cancer. Written by experts in the field on the cutting edge of this research, the following questions will be answered for the reader by the end of the book: · Who is at elevated risk for breast cancer? · Who should be genetically screened? · When and how often should we obtain imaging? · What type of imaging is adequate? · What medications are available for prevention? · When is surgical intervention appropriate? · What lifestyle changes should be implemented to prevent this disaster? With one in eight women likely to contract breast cancer in her lifetime, the significance of identifying and managing the high-risk patient is evident. Breakthroughs in the identification of genes associated with breast carcinoma, particularly BRCA1 and 2, as well as other risk factors, influence not only how patients are screened, but also how they are treated. Breast Cancer Prevention and Treatment provides a guided approach to prevention of breast cancer in women at elevated risk for this malignancy.
Health & Sickness -- Consumer Health This book by a scientist whose background is in cellular and molecular biology examines the fearsome disease that strikes one in eight women in the United States. Although women are more likely to die of heart disease or of lung cancer, a diagnosis of breast cancer is the medical pronouncement that a woman is most likely to fear. It kills more than 40,000 Americans annually. Why are some women more vulnerable than others? The interplay between genetics and environment is suspected. Thus this book for general readers will help them understand the genetic bases of both sporadic and inherited breast cancers. Although only five to ten percent of breast cancer patients have inherited mutations in these genes, all women need to understand the genetic implications of the disease. In clear, concise language Barbara T. Zimmerman guides the reader through the complexities, discussing in detail the genes that are known to increase susceptibility and the ways they are passed on. Examining the general biology of breast cancer, Zimmerman describes how sporadic and inherited forms of the disease arise and how the location of the tumors can affect the body. She discusses genetic mutations and their roles in the development of tumors and tells how these potentially cancer-inducing genes were discovered. Covered too are the issues of risk, prevention, screening, diagnosis, therapy, and genetic testing and counseling. Zimmerman concludes with a comprehensive analysis of current research and with an emphasis on how a woman's understanding of inherited breast cancer can help doctors seeking to design better methods for prevention and therapy. A useful list of resources for further information about the genetic causes of breast cancer is included. Barbara T. Zimmerman did her graduate work in experimental pathology and her post-doctoral research in the cellular and molecular processes of disease. Widely published, she is the manager of the Denver-based firm Biomedical Communication and Consulting.

Genetic susceptibility refers to how variations in a person’s genes increase or decrease his or her susceptibility to environmental factors, such as chemicals, radiation and lifestyle (diet and smoking). This volume will explore the latest findings in the area of genetic susceptibility to gastrointestinal cancers, focusing on molecular epidemiology, DNA repair, and gene-environment interactions to identify factors that affect the incidence of GI cancers. Topics will include germline susceptibility, including Mendelian patterns of inheritance and gene-environment interactions that lead to cancer etiology.
