Abstract
Context: Gastric carcinoma (GC) is the most commonly diagnosed cancer that has been one of the main causes of cancer death worldwide. The matrix metalloproteinase-2 (MMP2) gene was expressed in the gastric cancer tissues compared to the matched normal tissues that are associated with the metastasis of gastric cancer cells. Objectives: This systematic review was performed to investigate the role of MMP-2 in gastric cancer among the different population. Evidence Acquisition: We searched on electronic databases such as PubMed, Scopus, Science Direct and Cochrane Library Database without any language restriction for relevant publications which were published until April 2019. Results: Thirty two original and relevant studies that evaluate the association between gastric cancer and MMP-2 were included. This systematic review indicated that increased MMP-2 expression has been seen in gastric cancer. MMP-2 over-expression may play a crucial role in degrading extracellular matrix as well as stimulate angiogenesis. Conclusions: MMP2 over-expression can play a critical role in tumor metastasis, tumor size, invasion, and lymph node invasion in GC.
