                cancer is one of the most common causes of cancer-related deaths, 
                despite its decreasing incidence. Rapid progress has been achieved 
                in recent years in elucidating tumorigenesis and a multifactorial 
                model of human gastric carcinogenesis is currently accepted. It 
                is now evident that the critical genetic alterations are different 
                in diffuse and intestinal type gastric cancer. Moreover, the role 
                of E-cadherin gene alterations is elucidated in sporadic as well 
                as in hereditary diffuse gastric cancer. In the present review 
                recent advances in molecular Pathology of gastric cancer are discussed..
