Core Tip

Core tip: Despite recent advances in our understanding of the molecular and cellular events involved in gastric cancer, little is known about how gastric premalignant lesions actually lead to this usually lethal disease (5 years survival about 20% in most Western countries). It is still not clear whether some or all of these lesions are directly involved in the process of gastric carcinogenesis or whether they are simply bystanders. In this review, we attempt to shed some light into how our current understanding of premalignant lesions may be used to improve patient stratification and lead to better overall patient survival rates.
