Gastric cancer (GC) is the fourth most common cancer and the second leading cause of cancer-related mortality in the world. Late diagnosis and classical therapeutic approaches such as surgery, chemotherapy and radiotherapy make this disease a still threatening tumor. Genetic asset, environmental stress, dietary habit and infections caused by Helicobacter pylori (H. pylori) are the major causes concurring to GC initiation. A common mechanism is induction of radicals resulting in gastric mucosal injury. A regular food intake of antioxidant and radical scavenging agents has been proposed to exert protection against tumorigenesis. Resveratrol belongs to the polyphenol flavonoids class of antioxidants produced by a restricted number of plants. Resveratrol exerts bactericidal activity against H. pylori and is a powerful antioxidant, thus acting as a tumor preventive agent. Resveratrol intracellular signaling results in growth arrest and apoptosis, so that it can be directed against tumor progression. Resveratrol therapeutic potential against GC initiation and progression are reviewed here.
