Abstract
Cancer is recognized as a genetic disease resulting from alterations of genes or other genetic elements involved in cellular activities including proliferation, differentiation, apoptosis, maintenance of genetic stability, and cellular metabolism and intercellular interactions. The structural organization of genetic material into chromosomes, the major types of genes, and genetic regulatory processes related to cancer development are reviewed in this introductory chapter in the viewpoint of molecular oncology, focusing on the important genes and alterations related to the diagnosis, classification, disease monitoring, and targeted therapy of cancer. Frequent types of genetic abnormalities related to cancer development are explained from a molecular pathologist’s perspective and in relation to the methods used in the clinical diagnostic laboratories for the detection of cancer-related mutations and other genetic alterations. The concept of noncoding RNA and its potential role in tumorigenesis are discussed. The general principles of classifying genetic abnormalities and standardized nomenclature of mutations are introduced based on the national guidelines and consensus. Selected cases are presented to illustrate how the molecular test results are interpreted to help understand the pathobiology of cancer, and how these results can facilitate the final diagnosis and provide critical information for clinical management.
