Survivin c.-31G>C (rs9904341) gene transversion and urinary system cancers risk: a systematic review and a meta-analysis.

To investigate the possible association between survivin c.-31G>C (rs9904341) gene polymorphism and urinary system cancers by a meta-analysis approach. Standard electronic literature databases were searched to find eligible studies. The odds ratios (ORs) with 95% CIs were estimated to find the associations possibility. Overall meta-analysis revealed significant associations between c.-31G>C transversion and risk of urinary tract cancers in dominant (OR: 1.34; 95% CI: 1.02-1.75; p = 0.035), recessive (OR: 1.52; 95% CI: 1.33-1.74; p < 0.001) and homozygote codominant (OR: 1.90; 95% Cl: 1.37-2.62; p < 0.001) genetic models. The c.-31G>C transversion might be a risk factor for urinary system cancers. However, more articles with different ethnicities will help to obtain a more accurate conclusion.
