GASTRIC CANCER: MOLECULAR AND GENETIC DATA (LITERATURE REVIEW)

Abstract

In the review a data about molecular and genetic aspects of different morphological variants of gastric cancer in population and family studies are generalized. Data about multiple genetic and epigenetic damages in oncogenes, tumor suppressor genes, cell cycle regulators, adhesion molecules, DNA repair genes as well as genetic instability and telomerase activation involved in the multistep process of carcinogenesis and making a contribution to uncontrolled growth and ability to form metastases are included in the review. In article possibilities of use of specific molecular markers for early GC diagnostics are discussed.
