Objective  To investigate the correlation between RUNX3 expression and human gastric cancer, as well as its clinically pathologic features.
Methods  Such databases as PubMed, EMbase, VIP, WanFang Data and CBM were searched from their inception to February 28th, 2013 to collect case-control studies about the correlation between RUNX3 expression and human gastric cancer, as well as its clinically pathologic features, and the relevant references of the included literature were also retrieved. Two reviewers independently screened the literature according to the inclusion and exclusion criteria, extracted the data, and assessed the methodological quality. Then meta-analysis was conducted using RevMan 5.0 software.
Results  A total of 6 case-control studies were included, which included 405 cases in the gastric cancer group and 185 cases in the normal gastric mucosa group. The results of meta-analysis showed that, RUNX3 expression was lower in the gastric cancer group than the normal gastric mucosa group, with a significant difference (OR=0.07, 95%CI 0.04 to 0.12, P lt;0.000 01); it was also lower in the subgroup of gastric cancer accompanied with lymph node metastasis than that without lymph node metastasis (OR=0.37, 95%CI 0.23 to 0.61, P lt;0.000 1); but it was higher in the subgroup of gastric cancer that had infiltrated into serosa than that had not, with a significant difference (OR=3.92, 95%CI 2.29 to 6.71, P lt;0.000 01); and it was also higher in the subgroup of well differentiated gastric cancer that the moderately and poorly differentiated, with a significant difference (OR=0.36, 95%CI 0.22 to 0.58, P lt;0.000 1).
Conclusion  RUNX3 expression is notably correlated to gastric cancer and its clinically pathologic features. For the quantity and quality limitation of the included studies, this conclusion still needs to be further proved by performing more high quality studies.
