Received Sep 28; Accepted Nov There are a fair number of books, dealing with cancer biology; unfortunately, they arelimited to certain cancertypes and dated. Here, Pelengaris and Khan familiarize the reader with the cancer cell in Chapter one and selected human cancers in Chapter two. A capturing, comprehensive, clearly written and absolutely accurateintroduction into cancer biology, necessary to understand how tumors evolve, develop and progress is offered in Chapters three through fourteen. This book deserves great praise for the readable presentation of this complex field. Nothing is simplified for the sake of the flow of the text. A brief description of the content of Chapters three to fourteen is presented below. Chapter three focuses on 'nature and nurture in oncogenesis' with emphasis on the role of environmental carcinogens and the influence of environmental as well as individual risk factors on development and progression of cancers along with a brief introduction into the multi-stage-concept of cancers. DNA replication and cell cycle are discussed in Chapter four. In turn, the foundation to comprehend one of the hallmarks of cancer — uncontrolled progression through the cell cycle — is provided. Logically, interested readers find an introduction into the regulation of growth in Chapter five. For example, growth factors and cognate receptors, signaling pathways, cellular senescence, apoptosis and survival are elegantly introduced and woven into an appropriately simplified view with plenty of cited reference for further reading.

In sum, the philosophical approach to cancer biology and all related topics discussed in the book, along with well-chosen aphorisms, capture the attention of a reader and stimulate creative reading. Especially pleasing is the construction of chapters into introduction, classical experiments, conclusions and future directions.

Study questions and topical suggestions for further readinground the chapter into a rich source of information.

Introduction to Cancer Biology

Balancing the wealth of molecular and cellular information, it is re-iterated that caring for the cancer patient must be part of any successful attempt to manage or, in the best case, cure this devastating disease. In this context, the book covers aspects of diagnosis and treatment of cancer in order to provide a full view of efforts to understand cancers at the most detailed levels, yielding profound strategies to prevent and cure malignancies.

Diagnosis of cancer, its treatment options and the concept of patient care are presented in Chapters fifteen through seventeen. Here, the true synthesis of bench and bedside approaches is marvelously achieved by giving a thoughtful background in the role of molecular pathology in cancer diagnosis and staging, imaging techniques, radio- and chemotherapy, palliative care and the quality of a life at its end with numerous examples of recent developments and practical and ethical issues around cancer research.

The only weakness of the bookis the last chapter, dealing with genomic and proteomic approaches in cancer research and diagnostic. While the chapter in itself is superbly written and of outstanding merit, it could have been incorporated into the Chapters three through fourteen, thus, elevating this book to the status of a classical textbook.

Back to top Other genetic aspects of cancers Apart from the three major types of genes frequently altered in cancer, i. Back to top Genetic instability of tumour cells Genetic analysis of solid tumours revealed the presence of a high degree of genetic abnormalities, such as aneuploidy, chromosome translocations etc.

This is likely due to the lack of active p53 protein, and the ability of cancer cells to avoid cell death through apoptosis. Other mechanisms may also play a part here, e. Chromosomal instability CIN is widespread in cancer cells from epithelial origin, but much rarer in haematopoietic tumours.

Alteration of genetic mechanisms in cancer Three different alterations of genetic mechanisms often observed in cancer will be briefly explained below.

Loss of heterozygosity LOH : This describes a genetic phenomenon often seen with tumour suppressor genes in cancer.

Since the human karyotype is diploid, mutation of one allele of a tumour suppressor gene is not sufficient to cause cancer. In heterozygous individuals, the wildtype allele will provide for a functional phenotype. Genetic analyses of LOH helped to identify the chromosomal location of many tumour suppressor genes. Microsatellite instability MIN : This is a phenomenon often seen in colorectal cancer cells with defective DNA mismatch repair system, e.

Microsatellites are regions of repetitive DNA sequences in the genome that are prone to shortening or extension if the mismatch repair enzymes are defective.

Genetic analysis of these regions can be used to identify such defects. DNA hyper- or hypomethylation: DNA methylation of gene promoter regions on CpG cytosine-phosphate-guanine sequences is an important epigenetic control mechanism to silence specific genes. In cancer, DNA hypermethylation is often involved in the silencing of tumour suppressor genes. Conversely, DNA hypomethylation may contribute to the activation of oncogenes, although the former occurs much more commonly.

Inherited predisposition to cancer Whilst cancer as such is not inherited, there are a wide range of rare familial syndromes that predispose affected family members to cancer development. We mentioned above cancer predisposition syndromes that are based on mutations in DNA repair enzyme systems Table 4, in The importance of DNA repair systems.

A by far larger number of familial cancer syndromes is based on mutations of tumour suppressor genes, of which a selection is shown in Table 2. It is interesting to note that germ line mutations of activated oncogenes are normally not inherited. They may arise during gametogenesis, but the mutant alleles are typically dominant at the cellular level, which results in disturbance of normal embryonic development, and reduced viability of these embryos. Fortunately, the inherited cancer predisposition syndromes listed in Tables 2 and 4 are extremely rare diseases, but they represent powerful illustrations for the importance of DNA repair and tumour suppressor genes for maintaining body homeostasis.

Principal applications of genetic testing in cancer As an increasing number of cancer-related genes or gene mutations is characterised, the potential of DNA and RNA expression testing for cancer-related applications is being explored.

Principal applications include: Gene mutation screening in families with inherited cancer predisposition syndromes, which identifies at- risk individuals in such families and allows for decisions to be made about early disease monitoring, aggressive treatment regimens and prophylactic surgery e. Gene expression microarray analysis can be used for classification of cancer subtypes, e. Other applications include the diagnosis of benign vs. Tumour cells may be recognised by the immune system through the expression of tumour-associated antigens, but the antigenicity varies considerably between different types of antigens.

In order to avoid an attack by the immune system, tumour cells use a range of strategies, such as suppression of expression of tumour-associated antigens or of MHC class 1 molecules, or even counterattack against immune cells.

Research into immunotherapy of cancers aims to devise novel strategies to support the anti-cancer immune response; principal approaches include: Antigen-independent cytokine therapy e.
