The transformation of a normal cell into a cancer cell is not a sudden but a slow continuous process which may take years. A systematic study of the morphological and structural changes that take place during this cellular transformation has only become possible since methods were developed to induce a high incidence of tumors in experimental animals. The growth of such tumors can be followed during all stages of their development. For several reasons, rat liver has proved to be particularly suitable. For more than thirty years it has been known that one can induce tumors in rat liver experimentally with many different substances. The azo dyes which were used originally (YOSHIDA, 1932; KINOSITA, 1937) have since been replaced by more potent carcinogens. The recently discovered nitrosamines, dimethylnitrosamine (MAGEE and BARNES, 1956), diethylnitrosamine (SCHMAHL et aI. , 1960) and N-nitrosomorpholine (DRUCKREY et aI. , 1961) should be mentioned in this context. Used in the proper dose, these carcinogens lead within a few months to the formation of multicentric hepatomas in practically 100 Ufo of the experimental animals, and are therefore a very useful tool for studies of the cytogenesis of cancer (see BUCHNER, 1961; GRUND MANN, 1961; GRUNDMANN and SIEBURG, 1962; OEHLERT and HARTJE, 1963; BAN NASCH and MULLER, 1964). The liver parenchyma as such offers a very big technical advantage because it consists of a rather homogenous cell population.

The book addresses controversies related to the origins of cancer and provides solutions to cancer management and prevention. It expands upon Otto Warburg's well-known theory that all cancer is a disease of energy metabolism. However, Warburg did not link his theory to the "hallmarks of cancer" and thus his theory was discredited. This book aims to provide evidence, through case studies, that cancer is primarily a metabolic disease requring metabolic solutions for its management and prevention. Support for this position is derived from critical assessment of current cancer theories. Brain cancer case studies are presented as a proof of principle for metabolic solutions to disease management, but similarities are drawn to other types of cancer, including breast and colon, due to the same cellular mutations that they demonstrate.

This book covers all liver tumors and lesions that clinically and radiologically mimic liver tumors. It provides readers with a comprehensive overview of this complex and rapidly evolving field. All aspects of surgical pathology are addressed, supplemented by detailed presentations of the lesions’ cell-biologic and molecular features. In addition, the methods employed for diagnosis and diagnostic algorithms are discussed. It appeals to pathologists and hepatologists and serves as an invaluable aid to diagnosis.The field of liver tumors and tumor-like lesions in adults and children has experienced tremendous advances in recent years. Specifically, the recognition of novel entities, deepened insights into known tumors, and refinement of classifications have necessitated continual updates and reappraisals. In addition, previous understanding of hepatic carcinogenesis and tumor progression has been transformed by the very rapid evolution of our understanding of cell biology, genomics, signaling pathways, cell interactions, and mechanisms of invasion and spread of hepatic tumor cells. These general pathology issues must be combined with surgical pathology if a comprehensive understanding of liver tumor pathology is to be achieved.

This book covers all of the diagnostic areas where FNAC is used today. This includes palpable lesions and lesions sampled using various radiological methods, and correlations with ancillary examinations detailed on an entity-by-entity basis. As well as being a complete atlas of the facts and findings important to FNAC, this atlas is a guide to diagnostic methods that optimize health care. The interaction of the cytologist or cytopathologist with other specialists (radiologists, oncologists and surgeons) involved in the diagnosis and treatment of patients with suspicious mass lesions is emphasized and illustrated throughout. With contributions from experts in the field internationally and abundant colour images Atlas of Fine Needle Aspiration Cytology provides a comprehensive and up-to-date guide to FNAC for pathologists, cytopathologists, radiologists, oncologists, surgeons and others involved in the diagnosis and treatment of patients with suspicious mass lesions.

The Role of Cell Types in Hepatocarcinogenesis provides the first comprehensive, review and analysis of cell precursor relationships believed to be important in the development of hepatocellular carcinoma and other types of nonmesenchymal liver tumors. The book focuses on cell lineages in liver development and neoplastic formation in both experimental animal models and humans. It also critically reviews current information supporting the existence of a "facultative liver stem cell" and its potential role as an alternative cell of origin in the genesis of various hepatic neoplasms, including hepatocellular carcinoma. Other significant topics covered include cellular and viral oncogenes, p53 gene and growth factors in hepatocarcinogenesis, and the use of newly developed transgenic animal and cell culture models designed for investigating the pathogenesis of hepatocellular carcinoma. Numerous figures and tables illustrate difficult concepts, and an extensive listing of references is included. The Role of Cell Types in Hepatocarcinogenesis is a practical reference volume that basic and clinical researchers in liver carcinogenesis, development, and differentiation will find useful in their day-to-day work.

"chemical carcinogenesis" is the general title of the series of international meetings which are held, biannually, in sardinia (Italy) since 1981. Despite the generality of the title, the main effort of the scientific Committee has been to pursue a coherent line around one of the most distinguishing features of carcinogenesis: the "multifasic" development of the process. Given that many chemical compounds are known to cause "experimental cancer", many questions still remain unresolved or are given too simplistic answers. The very first question concerning the interaction between the chemical carcinogen and the molecular target in the cell is a debatable one despite the overwhelming literature in this field. It is certain that chemical carcinogens are toxic to cells and cause DNA damage: however it is still an open question as to how to relate these changes to the different stages of carcinogenesis including initiation. We have not to forget that 1/3 to 2/3 of the average life time of a given species elapses between the experimental administration of the carcinogen and the appearance of "cancer". The experimental manipulation of carcinogenesis through the use of "adequate biological models" has not simplified the problems about cancer, but it has led us to face the complexity of otherwise elementary biological properties, cell proliferation and differentiation. The understanding of this biological complexity is not just theoretical, but it may give us those adequate conceptual tools to approach "cancer" also from a medical point of view.
