Gastric cancer is one of the most common cancers and most frequent causes of cancer-related deaths in the world. The overall survival rate is 15-20%. Although the incidence is declining, its prognosis remains poor. The etiological factors and pathogenesis of gastric cancer are not yet fully understood. The integrated research in molecular pathology clarified the details of genetic and epigenetic abnormalities of cancer-related genes in the course of development and progression of gastric cancer. Although epidemiological evidences indicate that environmental factors play a major role in the carcinogenesis, the role of immunological, genetic and immunogenetic factors are thought to contribute to etiopathogenesis of gastric carcinoma. In addition to better understanding of pathogenesis of gastric cancer, the incidence, diagnostic studies and the therapeutic options have also undergone important changes in the last decade. There is ongoing debate regarding the role of adjuvant treatment. In advanced disease, palliation of symptoms, rather than cure, is the primary goal of patient management. Several combination therapies have been developed and have been examined in phase III trials; however, in most cases, they have failed to demonstrate a survival advantage over the reference arm. This review summarizes the newer concepts of molecular biology on gastric carcinogenesis and the new important recommendations for the management of patient with gastric carcinoma.
