Hiv Aids Associated Viral Oncogenesis

One of the most important aspects of AIDS is the loss of protective immune function in the infected host which leads to increased prevalence of opportunistic infections and cancers. This book specifically addresses viral-induced human cancers associated with AIDS and observed in the AIDS population. It addresses the specific treatment required in this special population and the molecular biology of the causative viral agents.

The association between AIDS and cancer was recognized from the beginning of the AIDS epidemic, when the appearance of Kaposi sarcoma in a cluster of young men was one of the first signs of this new disease. It was soon recognized that AIDS was caused by infection with a novel virus (HIV) and that AIDS patients are prone to develop a number of “AIDS-defining” cancers: Kaposi sarcoma, lymphoma, and cervical cancer. The development of effective combination anti-HIV therapy starting around 1996 converted AIDS from a death sentence to a manageable disease and led to dramatic shifts in the epidemic. As this therapy was able to improve immune function in patients, the incidence of most “AIDS-defining” cancers decreased. There is a misconception, however, that AIDS has gone away. In fact, as AIDS patients are living longer, the number of AIDS patients has more than doubled in the United States since 1996, and the AIDS population overall has increased in age. Also, as AIDS patients are less likely to die of other complications, cancer is coming to the forefront as one of the most common causes of death in regions where AIDS drugs are widely available. Moreover, the three “AIDS-defining” cancers are now taking a back seat to a number of other HIV-associated cancers, such as Hodgkin lymphoma, lung cancer, and anal cancer. In the developing world, AIDS-associated cancers are a major public health problem, and in some regions of sub-Saharan Africa, Kaposi sarcoma is the most common tumor in men. In recent years, there has been a vast increase in our understanding of HIV-associated cancers. We now know, for example, that most are caused by other viruses and that the main role of HIV and immunodeficiency is to provide a supportive environment for the viruses to multiply and for the cancers to develop. But there remain a number of unanswered questions and a need for improved prevention and therapy. In the 28 chapters of this book, written by some of the most renowned experts in this field, we present up-to-date information on the cancers associated with HIV infection. The chapters cover the epidemiology of these cancers, their pathogenesis, their clinical presentation, and their treatment. The book will be of value to physicians, other medical professionals, students, and researchers with an interest in AIDS, viral-associated cancers, or HIV-associated malignancies.

Cancer incidences increase in people living with HIV/AIDS. Over 2 million people currently live with HIV/AIDS in the US. This number will increase as HAART prolongs the average lifespan and as (at least in some states) the number of new HIV infections increase again. As this population ages their incidence rates for cancer will increase, as well. Recently, new rational targets for cancer therapy have emerged. But their application to the care of HIV+ patients is slow, because of concerns about the weakened immune status of the patients, because of possible drug interactions with HAART and because some of the AIDS defining cancer are rare.

This comprehensive account of the human herpesviruses provides an encyclopedic overview of their basic virology and clinical manifestations. This group of viruses includes human simplex type 1 and 2, Epstein–Barr virus, Kaposi's Sarcoma-associated herpesvirus, cytomegalovirus, HHV6A, 6B and 7, and varicella-zoster virus. The viral diseases and cancers they cause are significant and often recurrent. Their prevalence in the developed world accounts for a major burden of disease, and as a result there is a great deal of research into the pathophysiology of infection and immunobiology. Another important area covered within this volume concerns antiviral therapy and the development of vaccines. All these aspects are covered in depth, both scientifically and in terms of clinical guidelines for patient care. The text is illustrated generously throughout and is fully referenced to the latest research and developments.

Viruses are the causes of approximately 25% of human cancers. Due to their importance in carcinogenesis, there is a desperate need for a book that discusses these viruses. This book is therefore timely, providing a comprehensive review of the molecular biology of oncogenic viruses and the cancers they cause. Viruses that are discussed in the individual chapters include hepatitis B virus, hepatitis C virus, human papilloma viruses, EpsteinOCoBarr virus, Kaposi's sarcoma virus and human T-cell leukemia virus type 1. This book provides up-to-date information for graduate students, postdoctoral fellows, medical students, physicians and non-experts who are interested in learning more about the oncogenic viruses and how they cause human cancers.

Clinical oncologists and researchers now have a comprehensive single source of current information on cancer viruses obtained from bench and bedside. This important refernce allows further development of translational approaches for the effective treatment of patients with virus-associated malignancies. The book contains 25 chapters covering basic and clinical aspects of viruses, including HPV, HBV, HCV, polyomaviruses, Kaposi’s associated viruses, retroviruses (including HIV-1 associated malignancies), and EBV. Several chapters are devoted to basic science of oncogenic viruses for the study of their pathogenesis, drug development, and employment of viral vectors for vaccine and gene therapy. Clinical materials are embedded within chapters, and there are also complementary, clinically based chapters describing natural courses and treatments.
