X-ray cross-complementing groups 1 (XRCC1) rs1799782 C>T polymorphisms and colorectal cancer susceptibility were not clear. The purpose of this study was to evaluate the association between XRCC1 rs1799782 C>T polymorphisms and colorectal cancer susceptibility by meta-analysis. ⋯ Chinese Han people with rs1799782 TT/CT genotype of XRCC1 gene may have increased risk of developing colorectal.

To assess whether the Helicobacter pylori (HP) infection can increase the risk of developing pancreatic cancer or not by meta-analysis. ⋯ Based on present open published data, HP infection can significantly increase the risk of developing pancreatic cancer. However, for small number of studies included in this meta-analysis and publication bias, more case-control or cohort studies are needed to further confirm this conclusion.
