Although tobacco and alcohol consumption are two common risk factors of head and neck cancer (HNC), other specific etiologic causes, such as viral infection and genetic susceptibility factors, remain to be understood. Hu- man DNA is often damaged by numerous endogenous and exogenous mutagens or carcinogens, and genetic vari- ants in interaction with environmental exposure to these agents may explain interindividual differences in HNC risk. Single nucleotide polymorphisms (SNPs) in genes involved in the DNA damage-repair response are reported to be risk factors for various cancer types, including HNC. Here, we reviewed epidemiological studies that have assessed the associations between HNC risk and SNPs in DNA repair genes involved in base-excision repair, nucleotide-excision repair, mismatch repair, double-strand break repair and direct reversion repair pathways. We found, however, that only a few SNPs in DNA repair genes were found to be associated with significantly in- creased or decreased risk of HNC, and, in most cases, the effects were moderate, depending upon locus-locus in- teractions among the risk SNPs in the pathways. We believe that, in the presence of exposure, additional pathway- based analyses of DNA repair genes derived from genome-wide association studies (GWASs) in HNC are needed.
