Gastric cancer in Mexico is the most frequent gastrointestinal malignant neoplasm. Several precursor conditions, such as chronic gastritis, have been associated with the development of gastric cancer. The gelatinases MMP-2 and MMP-9, members of the metalloproteinase family, are fundamental enzymes in extracellular matrix remodelling.
