To scientists, oncology means research on the disease of cancer. The connection between basic research and clinical oncology, however, is not always very clear. Basic research sometimes appears to be an art that is practiced for its own sake and admired for its perfection. The clinician wishes to interpret the issues addressed by basic research, as he is eager to obtain answers to the questions that clinical oncology leaves open. These are, among others, questions as to the etiology and pathogenesis of neoplasma in human beings. In spite of all the technological advances during the past 10 years, the guidelines for new treatments of human leukemias and tumors are still unsatisfactory. The dialogue between researchers and clinicians must never cease, so that these questions can be formulated in such a way that science may be able to answer them. Both parties should cooperate whenever this is useful and possible. Prospectively planned clinical trials on the diagnosis and therapy of neoplasias offer a good opportunity for research involving patients. Tumor and/or blood tests run by reference laboratories on a great number of patients with the same diagnosis can lead to clinically relevant basic research. Using clinical studies in basic research programs permits us to trace missing pieces in the puzzle of cancer and put them into place.

Sex steroids, including androgens, estrogens, and progestogens, are known to have widespread physiological actions beyond the reproductive system via binding to the sex hormone receptors. Meanwhile, emerging evidence has indicated that sex hormone receptor signals are involved in the outgrowth of some malignancies, such as prostate and breast carcinomas, as well as others that have not traditionally been considered as endocrine-related neoplasms. This Special Issue “Sex Hormone Receptor Signals in Human Malignancies” covers various aspects of the potential role of sex hormone receptors and related signals in prostate cancer, breast cancer, and other neoplastic conditions by depicting promising findings derived from in vitro and in vivo experiments as well as the analyses of surgical specimens. The current observations described may thus provide a unique insight into novel or known functions of sex hormone receptors and related molecules.

The first edition of Oncogenes (1989) focused on several of the better known transforming mechanisms and surveyed a spectrum of solid tumors and hematologic malignancies. Several of the nearly 50 known oncogenes most relevant to human disease were examined. In contrast, this volume presents a very different profile and balance of subject material that reflects the rapidly changing field of molecular oncology and its newly emerging concepts. Among the most important discoveries of the past 4 years are the identification of nearly a dozen different tumor suppressor genes and the finding of an entirely new class of cancer-causing gene (bcl-2) that acts by inhibiting cell death rather than stimulating cell proliferation. This edition begins by reviewing selected malignancies in which our earlier search for clinically relevant oncogenes has led to more focused studies on gain-of-function and loss-of-function genetic abnormalities, as well as autocrine and paracrine growth factor loops known to regulate tumor physiology and malignant cell behavior. Curiously, many of these genetic and functional abnormalities are shared by several different tumor types and are not uniformly present in all tumors of the same type. This observation brings up molecular questions about the tissue-specific determinants that underlie individual cancers and also gives added impetus to the suggestion that molecular abnormalities (referred to as tumor markers) be included among the histopathologic features used for clinical diagnosis and manage ment.

Scientists and physicians share overlapping interests in fundamental cancer biology and in the potential clinical ramifications of specific mutations in cancer cells. In this volume, they present their ideas on the role of oncogenes and their protein products in human tumors, with emphasis on diagnostic applications. They also review the medical implications of discoveries concerning the genetic basis of neoplastic disease. Topics include nuclear oncogene proteins; growth factors and their receptors; activation of ras, src, and raf oncogenes; chromosomal rearrangements associated with oncogene activation; gene loss in human cancers; the identification and potential function of anti-oncogenes ; the genetic basis for the resistance of tumor cells to chemotherapeutic drugs; and DNA tumor virus oncogenes in some human cancers. Molecular Diagnosis of Human Cancer also includes technical advances, as well as data on the diagnostic and prognostic implications of particular oncogene alterations in a number of cancers, notably pediatric neuroblastoma, the myelogenous leukemias, and carcinomas of the colon, bladder, pancreas, and breast.

This book is about Nutraceuticals in cancer therapy, specifically targeted and Adjuvant therapy. It shows several approaches for possibly reducing systemic toxicity. This book illustrates the role of several dietary agents, collectively called nutraceuticals or natural agents in the prevention and/or treatment of human malignancies known to be mediated through alterations in multiple molecular targets. This book contains sixteen chapters which begin with historical perspective on the value of natural agents in the prevention of human malignancies followed by a series of current topics on multiple nutraceuticals targeting multiple cancers. This collection would likely be useful for bringing newer generations with broader perspectives in launching cutting-edge innovative molecular research, which would certainly help in designing targeted clinical trials in order to realize the dream of customize strategies for the prevention and/or treatment of human malignancies without causing any systemic toxicity. Moreover, the knowledge gained would allow novel utilization of nutraceuticals as adjunct to both conventional chemotherapy and radiation therapy in order to improve the overall quality of life and survival of patients diagnosed with cancers.

The immune system can deal effectively with the majority of viruses and bacteria, less effectively with parasites, and very poorly with cancer. Why is this so? Why are McFarlane Burnet's and Lewis Thomas' predictions that the immune system is in volved in ridding the body of cancer cells, encapsulated in the catchy phrase "immunologic surveillance," so difficult to experi mentally establish? Cancer differs from infectious agents in being derived from the host. Hence, it has been postulated that cancer cells lack anti gens that the immune system can recognize. They are not "im munogenic. " However, this argument is seriously weakened by the existence of numerous human autoimmune diseases, in which the immune system effectively recognizes and attacks a va riety of self tissues. Thus, the potential clearly exists for recogni tion of the surfaces of tumor cells. Professor Naor and his colleagues have written a book that explores another possible reason: cancer cells are recognized by the immune system-but is it possible that the consequence of recognition is inhibition of the immune system-by suppressor T cells or macrophages? The evolution of the malignant state may only occur in individuals who develop this suppression. This book reviews the evidence that suppressor cells, poorly characterized and difficult to study, may be of fundamental im portance in cancer. In fact, our incapacity to understand the na ture of suppressor cells and their mode of action is one of the ma jor problems in immunology research today.

Continuous cell lines derived from human cancers are the mostwidely used resource in laboratory-based cancer research. The first 3 volumes of this series on Human Cell Culture are devoted to these cancer cell lines. The chapters in these first 3 volumes have a common aim. Their purpose is to address 3 questions offundamental importance to the relevanceof human cancer cell lines as model systems of each type of cancer: 1. Do the cell lines available accurately represent the clinical presentation? 2. Do the cell lines accurately represent the histopathology of the original tumors? 3. Do the cell lines accurately represent the molecular genetics of this type of cancer? The cancer cell lines available are derived, in most cases, from the more aggressive and advanced cancers. There are few cell lines derived from low grade organ-confined cancers. This gap can be filled with conditionally immortalized human cancer cell lines. We do not know why the success rate for establishing cell lines is so low for some types of cancer and so high for others. The histopathology of the tumor of origin and the extent to which the derived cell line retains the differentiated features of that tumor are critical. The concept that a single cell line derived from a tumor at a particular site is representative oftumors at that site is naïve and misleading.

Historically, the study of infection has focused on acute illnesses and their treatment. Infection, however, is not simply an acute process; microbial agents thrive in the human body throughout life. The unrecognized, intimate relationship we share with microorganisms is a critical factor in longevity and health. In recent years, it has become apparent that some cancers may be attributable to underlying chronic infection. Fortunately, infectious diseases are often treatable or preventable. Also, the composition of infectious agents is far less complex than that of humans. Thus the link between infection and cancer may offer insight into the pathogenesis and prevention of all cancers. This book, authored by some of the world's leaders in microbiology, virology, biochemistry, and pathology, provides an overview of oncogenic mechanisms imputed to infection. Individual chapters examine the epidemiologic, clinical and molecular links between specific infectious agents and cancer, and address methods of disease prevention. Microbiologists, cancer biologists, pathologists, oncologists, and infectious disease specialists interested in the etiology of malignancy will find this book an indispensable addition to their libraries.

In this book, outstanding researchers from the US and Japan review recent progress in Epstein-Barr virus research. Most people carry EBV in memory B-cells in a latent stage. Many malignancies such as T/NK cell lymphoma, AIDS-associated B-cell lymphoma, gastric carcinoma and Hodgkin's disease have been causally linked to EBV. The development of molecular biology technique has allowed us to study the roles of individual EBV genes that act in the maintenance and disruption of EBV latency.
