 Background: HIV-induced immunodeficiency has been implicated as a key factor for risk of cancer. Neoplasia is considered to result from accumulation of damage to the genome. Polymorphisms in repair genes, such as the XRCC1 and WRN, have been associated with susceptibility to development of cancer in patients with HIV/AIDS. The aim of this study was to analyze the frequency of polymorphisms in XRCC1 (Arg399Gln) and WRN (Cys1367Arg) in patients with HIV/AIDS with or without cancer. Materials and Methods: Genotyping for analysis of polymorphisms was carried out by PCR (Polymerase Chain Reaction) and RFLP (Restriction Fragment Length Polymorphism). Results: In the genotypic and allelic analysis, no increased risk of cancer was observed with any genotype or allele of XRCC1 (Arg399Gln) singly (prevalence ratio 2.82; p-value= 0.24). However, with the WRN (Cys1367Arg) gene, the heterozygous genotype and arginine allele were associated with increased risk (prevalence ratio= 25.62; p-value= 0.0001). Correlation analysis showed no association between gender and the risk (male p-value= 0.639 and women p-value> 1); however, a positive association for the increased risk of cancer was shown with  1); however, a positive association for the increased risk of cancer was shown with XRCC1 (Arg399Arg) wild-type homozygous and WRN (Cys1367Arg) heterozygous (p-valueXRCC1 (Arg399Gln) and WRN (Cys1367Arg) (p-valueXRCC1 (Gln399Gln) and heterozygous WRN (Cys1367Arg) (p-valuecarriers of the XRCC1 (Arg399Gln) gene singly. However, there is a high risk in patients with HIV/AIDS who have the heterozygous genotype and the arginine allele in the WRN (Cys1367Arg) gene singly. Those with WRN (Cys1367Arg) heterozygote genotype showed a high risk of cancer with all genotypes of the XRCC1 (Arg399Gln) gene.
