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.
