Abstract
This systematic review and meta-analysis were conducted to investigate the association between methylenetetrahydrofolate reductase (MTHFR) C677T and A1298C polymorphisms with breast cancer (BC) in Asians. Systematic searches were conducted in PubMed, EMBASE, Web of Science, and Scopus by May 2020. Inter-study heterogeneity was also assessed with a Q test, along with I2 statistics. Random-effects models were applied to pooled crude ORs with corresponding 95% CIs for the genetic models. A total of 1097 identified results, along with 36 qualified studies were included: for MTHFR C677T polymorphism, a total of 36 studies was comprised of 11,261 cases and 13,318 controls and for MTHFR A1298C polymorphism, a number of 19 studies contained 7424 cases and 8204 controls. Likewise, for C677T polymorphism, an increased risk of BC was seen for the allelic (OR 1.21, 95% CI 1.09-1.33, P < 0.01, I2 = 78.9%), dominant (OR 1.17, 95% CI 1.05-1.30, P < 0.01, I2 = 71.8%), recessive (OR 1.43, 95% CI 1.23-1.67, P < 0.01, I2 = 55.8%), and homozygous models (OR 1.48, 95% CI 1.25-1.75, P < 0.01, I2 59.9%) among BC patients compared to controls. Also, in terms of A1298C polymorphism, an association was found between the allelic (OR 1.15, 95% CI 1.04-1.28, P < 0.01, I2 70.4%) and homozygous models (OR 1.38, 95% CI 1.15-1.66, P < 0.01, I2 44.2%) with the risk of BC. In conclusion, findings revealed that MTHFR C677T variant might be a factor that predisposes BC in Asians. Furthermore, it was found that A1298C variant acts as a BC risk factor, particularly in a Western Asia population.

Abstract
Breast cancer is one of the most common malignancies in women worldwide and is associated with a variety of risk factors. Folate and vitamin B12 are key elements of the one-carbon metabolism pathway where methylenetetrahydrofolate reductase (MTHFR) plays a significant role. Though many molecular and epidemiological studies have been performed to explore the relationship between intake folate, vitamin B12, MTHFR gene polymorphism and breast cancer risk, there is no consensus to date. By reviewing the relevant literatures and summarizing the potential effect of dietary folate intake on MTHFR genes polymorphism and breast cancer risk, we conclude that MTHFR C677T gene polymorphism is associated with breast cancer risk among Asian, but not Caucasians, and the MTHFR A1298C gene polymorphism is not a susceptibility factor of breast cancers. Concomitant low activity of MTHFR enzyme resulted from C677T gene polymorphism and low dietary folate intake is associated with increased breast cancer risk.

C677T and A1298C methylenetetrahydrofolate reductase polymorphisms and breast cancer susceptibility among Latinos: a meta-analysis. Breast Cancer 2019; 26:602-611. [PMID: 30877449 DOI: 10.1007/s12282-019-00961-8] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/10/2018] [Accepted: 03/11/2019] [Indexed: 02/07/2023]
Abstract
BACKGROUND Previous meta-analyses have shown an ethnic dependency of the C677T and the A1298C methylenetetrahydrofolate reductase (MTHFR) polymorphisms, with no focus on the Latino population. For Latinos, many studies have examined these polymorphisms and breast cancer susceptibility, yielding no concise result. Therefore, we undertook this meta-analysis to determine the effect these polymorphisms have on breast cancer risk for Latinos. METHODS PubMed, EBSCO, LILACS, Scopus, and Latin American-specific databases were searched for studies exploring the association between the MTHFR polymorphisms and breast cancer susceptibility in Latinos until January 2019. Genotype distributions were extracted and, depending on the level heterogeneity determined by the ψ2-based Q test and the I2 test, fixed-effects or random-effects models were used to calculate pooled odds ratios (ORs) with 95% confidence intervals (95% CIs) for the heterozygous, homozygous, dominant, recessive, and allelic genetic models. No publication bias was detected by the Begg-Mazumdar's test and Egger's test. RESULTS Of the 280 retrieved publications, 9 studies were included: 9 for the C677T polymorphism and 5 for the A1298C polymorphism. For the C677T polymorphism, there was an elevated risk for the homozygous (OR 1.42, 95% CI 1.05-1.92), the dominant (OR 1.16, 95% CI 1.02-1.31), the recessive (OR 1.33, 95% CI 1.01-1.75), and the allelic model (OR 1.17, 95% CI 1.03-1.33, p < 0.01). No association between the A1298C polymorphism and the risk to develop breast cancer was determined. CONCLUSION The results indicated that, for Latinos, the C677T polymorphism is associated with a significant risk for developing breast cancer, whereas the A1289C polymorphism does not.

Abstract
Background: The rs1800871 and rs1800872 polymorphisms of interleukin 10 (IL-10) gene has been indicated to be associated with breast cancer (BC) risk, but study results are still debatable. To derive a more precise evaluation, we performed a comprehensive meta-analysis. Methods: Multiple electronic databases were searched to identify studies assessing the IL-10 rs1800871 and rs1800872 polymorphisms with BC risk. Results: A total of 21 case-control studies with 6054 cases and 6355 controls were included in this met-analysis. There was a significant association between the rs1800871 polymorphism and BC risk (CT vs. TT: OR= 1.17, 95% CI 1.01-1.35, p=0.02; and CC+CT vs. TT: OR= 1.29, 95% CI 1.00-1.66, p=0.04). Moreover, increased BC risks were also associated with the rs1800872 polymorphism (C vs. A: OR= 1.29, 95% CI 1.04-1.60, p=0.01; CC vs. AA: OR= 1.54, 95% CI 1.03-2.30, p=0.03; CC+CA vs. AA: OR= 1.43, 95% CI 1.01-2.01, p=0.03; and CC vs. CA+AA: OR= 1.23, 95% CI 1.01-1.51, p=0.04). A pooling of the studies was also conducted by ethnicity, but failed to show an association of IL-10 rs1800871 and rs1800872 polymorphism with BC risk in Asians and Caucasians. Conclusions: Our results are inconsistent with previous meta-analysis suggests that IL-10 rs1800871 and rs1800872 polymorphisms might contribute to BC susceptibility in overall population, but not by ethnicity.
