Recently, a functional polymorphism (rs2295080 T>G) in the promoter of MTOR has been shown to influence its expression and confer susceptibility to cancer.
Our meta-analysis results showed that the wild genotype TT of rs2295080 polymorphism was associated with increased cancer risk under dominant model (OR = 1.24, 95%CI: 1.12-1.36, p<0.0005) in Chinese but not with clinical outcome parameters, while the TT genotype of rs11121704 was associated with poor clinical outcome parameters (OR = 1.53, 95%CI: 1.01-2.32, p = 0.044), such as death, metastasis and resistance to chemotherapy.
When estimated these two SNPs together, the combined genotypes with 2-4 risk alleles (rs2295080 T and rs7254617 A alleles) were associated with an increased risk of PCa compared with 0-1 risk alleles, which was more pronounced among subgroups of age >71 years, smokers, drinkers and no family history of cancer.
