The previously published data on the association between CYP1A2*1C (rs2069514) and CYP1A2*1F (rs762551) polymorphisms and cancer risk have remained controversial.
The results showed that no significant associations with the risk of cancer were found in any model (allele contrast, codominant, dominant, or recessive model) in terms of rs2069514 and rs3569413 when all studies were pooled into a meta-analysis.
