“…The flowchart of the literature search and study inclusion is presented in Additional file 3: Figure S1. A total of 39 studies were identified as eligible for inclusion, including 32 case-control studies [15–31], 3 nested case-control studies [32–34] and 4 cohort studies [35–38]. The detailed characteristics of the 39 studies as well the present study are summarized in Additional file 4: Table S3.…”

Background The association of ABO blood groups with gastric cancer risk was proposed decades ago, but the results have been inconsistent. Methods We used two single nucleotide polymorphisms to determine ABO genotype in 4932 gastric cancer cases and 6158 controls of Chinese descent, and evaluated the associations of ABO blood groups and genotypes with risk of gastric cancer using multivariable logistic regression models. We also systematically reviewed published literature and performed a meta-analysis of all relevant studies. Results In the case-control study, compared with blood group O, both blood group A and AB were associated with increased gastric cancer risk (for group A, odds ratio (OR) = 1.13, 95% confidence interval (CI): 1.02–1.24; for group AB, OR = 1.18, 95% CI: 1.02–1.36, respectively). Analyses of ABO genotypes revealed associations of AO and AB with risk of gastric cancer compared with OO genotype. Consistent with the case-control study, meta-analysis of 40 studies including 33,613 cases and 2,431,327 controls demonstrated that blood group A (OR = 1.19, 95% CI: 1.13–1.25) and AB (OR = 1.09, 95% CI: 1.03–1.16) were associated with increased risk of gastric cancer. Conclusions Our analyses validated the association of blood group A with risk of gastric cancer, and suggested that blood group AB was also associated with gastric cancer risk. Functional investigations are warranted to elucidate the exact mechanism of ABO blood groups in gastric carcinogenesis.

Background: For decades, studies have been performed to evaluate the association between ABO blood groups and risk of cancer. However, whether ABO blood groups are associated with overall cancer risk remains unclear. We therefore conducted a meta-analysis of observational studies to assess this association. Materials and Methods: A search of Pubmed, Embase, ScienceDirect, Wiley, and Web of Knowledge databases (to May 2013) was supplemented by manual searches of bibliographies of key retrieved articles and relevant reviews. We included case-control studies and cohort studies with more than 100 cancer cases. Results: The search yielded 89 eligible studies that reported 100,554 cases at 30 cancer sites. For overall cancer risk, the pooled OR was 1.12 (95%CI: between ABO blood groups and overall cancer risk still remains unclear. Therefore, we conducted a systematic review and meta-analysis to evaluate the association between ABO blood groups and overall cancer risk, as well as the risk of individual cancer sites.1 Materials and Methods Search strategyWe performed a systematic literature search (up to May 2013) of Pubmed, Embase, ScienceDirect, Wiley, and Web of Knowledge for studies reporting the association between ABO blood groups (self-reported or lab tested) and cancer risk. In addition, we searched the reference lists of relevant articles and reviews. Only articles published in English were considered. Two search themes were combined using the Boolean operator 'and'. The first theme, cancer, combined exploded versions of the Medical Subject Headings (MeSH) cancer, tumor, carcinoma, neoplasm or malignancy. The second theme, blood group, combined exploded versions of MeSH terms blood group, or blood type.
