Abstract
Cancer is the leading cause of death in economically developed countries and the second leading cause of death in developing countries. The relationship between genetic polymorphisms and the risk of cancers has been widely researched. Excision repair cross-complementing group 2 (ERCC2) gene plays important roles in the nucleotide excision repair pathway. There is contrasting evidence on the association between the ERCC2 Asp312Asn polymorphism and the risk of cancer. We conducted a comprehensive meta-analysis in order to assess the correlation between these factors. We searched the PubMed, EMBASE, Science Direct, Web of Science, and CNKI databases for studies published from January 1, 2005 to January 1, 2016. Finally, 86 articles with 38,848 cases and 48,928 controls were included in the analysis. The overall analysis suggested a significant association between the ERCC2 Asp312Asn polymorphism and cancer risk. Furthermore, control source, ethnicity, genotyping method, and cancer type were used for subgroup analysis. The result of a trial sequential analysis indicated that the cumulative evidence is adequate; hence, further trials were unnecessary in the overall analysis for homozygote comparison. In summary, our results suggested that ERCC2 Asp312Asn polymorphism is associated with increased cancer risk. A significantly increased cancer risk was observed in Asian populations, but not in Caucasian populations. Furthermore, the ERCC2 Asp312Asn polymorphism is associated with bladder, esophageal, and gastric cancers, but not with breast, head and neck, lung, prostate, and skin cancers, and non-Hodgkin lymphoma. Further multi-center, well-designed studies are required to validate our results.

Abstract
Polymorphisms in DNA repair genes may alter DNA repair capacity and, consequently, lead to genetic instability and carcinogenesis. Several studies have investigated the association of the Asp312Asn and Lys751Gln polymorphisms in the xeroderma pigmentosum complementation group D (XPD) gene with the risk of non-Hodgkin's lymphoma (NHL), but the conclusions have been inconsistent. Therefore, we performed this meta-analysis to more precisely estimate these relationships. A systematic literature search was performed using the PubMed, Embase, and Chinese Biomedical (CBM) databases. Ultimately, 6 studies of Asp312Asn, comprising 3,095 cases and 3,306 controls, and 7 studies of Lys751Gln, consisting of 3,249 cases and 3,676 controls, were included. Pooled odds ratios (ORs) and 95% confidence intervals (CIs) were calculated to assess the strength of each association. Overall, no association was observed between the Asp312Asn polymorphism and NHL risk (homozygous: OR = 1.11, 95% CI = 0.94-1.32; heterozygous: OR = 1.00, 95% CI = 0.89-1.11; recessive: OR = 1.12, 95% CI = 0.95-1.31; dominant: OR = 1.02, 95% CI = 0.92-1.13; and allele comparison: OR = 1.04, 95% CI = 0.96-1.12) or between the Lys751Gln polymorphism and NHL risk (homozygous: OR = 0.97, 95% CI = 0.83-1.15; heterozygous: OR = 0.96, 95% CI = 0.86-1.06; recessive: OR = 1.00, 95% CI = 0.86-1.16; dominant: OR = 0.96, 95% CI = 0.87-1.06; and allele comparison: OR = 0.98, 95% CI = 0.91-1.05). Furthermore, subgroup analyses did not reveal any association between these polymorphisms and ethnicity, the source of the controls, or the NHL subtype. These results indicated that neither the Asp312Asn nor Lys751Gln XPD polymorphism was related to NHL risk. Large and well-designed prospective studies are required to confirm this finding.

Abstract
The Arg194Trp polymorphism in the X-ray cross-complementing group 1 (XRCC1) had been implicated in cancer susceptibility. The previous published data on the association between XRCC1 Arg194Trp polymorphism and cancer risk remained controversial. Hence, we performed a meta-analysis to investigate the association between cancer susceptibility and XRCC1 Arg194Trp (59,227 cases and 81,587 controls from 201 studies) polymorphism in different inheritance models. We used odds ratios with 95 % confidence intervals to assess the strength of the association. Overall, significantly increased cancer risk was found (recessive model: (odds ration [OR] = 1.18, 95% confidence interval [CI] = 1.09-1.27; homozygous model: OR = 1.21, 95% CI = 1.10-1.33; additive model: OR = 1.05, 95% CI = 1.01-1.09) when all eligible studies were pooled into the meta-analysis. In further stratified and sensitivity analyses, significantly increased glioma risk was found among Asians, significantly decreased lung cancer risk was found among Caucasians, and significant increased breast cancer risk was found among hospital-based studies. In summary, this meta-analysis suggests that Arg194Trp polymorphism may be associated with increased breast cancer risk, Arg194Trp polymorphism is associated with increased glioma risk among Asians, and Arg194Trp polymorphism is associated with decreased lung cancer risk among Caucasians. In addition, our work also points out the importance of new studies for Arg194Trp association in some cancer types, such as gastric, pancreatic, prostate, and nasopharyngeal cancers, where at least some of the covariates responsible for heterogeneity could be controlled, to obtain a more conclusive understanding about the function of the XRCC1 Arg194Trp polymorphism in cancer development (I (2) > 75%).

Abstract
Molecular and genetic evidence suggests that DNA repair pathways may contribute to lymphoma susceptibility. Several studies have examined the association of DNA repair genes with lymphoma risk, but the findings from these reports have been inconsistent. Here we provide the results of a focused analysis of genetic variation in DNA repair genes and their association with the risk of non-Hodgkin's lymphoma (NHL). With a population of 1,297 NHL cases and 1,946 controls, we have performed a two-stage case/control association analysis of 446 single nucleotide polymorphisms (SNPs) tagging the genetic variation in 81 DNA repair genes. We found the most significant association with NHL risk in the ATM locus for rs227060 (OR = 1.27, 95% CI: 1.13-1.43, p = 6.77×10(-5)), which remained significant after adjustment for multiple testing. In a subtype-specific analysis, associations were also observed for the ATM locus among both diffuse large B-cell lymphomas (DLBCL) and small lymphocytic lymphomas (SLL), however there was no association observed among follicular lymphomas (FL). In addition, our study provides suggestive evidence of an interaction between SNPs in MRE11A and NBS1 associated with NHL risk (OR = 0.51, 95% CI: 0.34-0.77, p = 0.0002). Finally, an imputation analysis using the 1,000 Genomes Project data combined with a functional prediction analysis revealed the presence of biologically relevant variants that correlate with the observed association signals. While the findings generated here warrant independent validation, the results of our large study suggest that ATM may be a novel locus associated with the risk of multiple subtypes of NHL.

Abstract
The genetic polymorphisms of X-ray repair cross complementing group 1 (XRCC1), X-ray repair cross complementing group 3 (XRCC3), and xeroderma pigmentosum complementation group D (XPD) repair genes may lead to genetic instability and leukemogenesis. The purpose of the study was to evaluate the association between XRCC1 Arg399Gln, Arg280His and Arg194Trp, XRCC3 Thr241Met, and XPD Lys751Gln polymorphisms and the risk of developing CML in Romanian patients. A total of 156 patients diagnosed with CML and 180 healthy controls were included in this study. We found no association between CML and XRCC1 or XRCC3 variant genotypes in any of the investigated cases. A significant difference was observed in the variant genotype frequencies of the XPD Lys751Gln polymorphism between the patients with CML and control group (for variant homozygous genotypes, OR = 2.37; 95% CI = 1.20–4.67; P value = 0.016 and for combined heterozygous and variant homozygous genotypes, OR = 1.72; 95% CI = 1.10–2.69; P value = 0.019). This was also observed when analyzing the variant 751Gln allele (OR = 1.54; 95% CI = 1.13–2.11; P value = 0.008). Our results suggest that the XPD Lys751Gln variant genotype increases the risk of CML.

Abstract
The damage caused by oxidative stress and exposure to cigarette smoke and alcohol necessitate DNA damage repair and transport by multidrug resistance-1 (MDR1). To explore the association between polymorphisms in these genes and non-Hodgkin lymphoma risk, we analyzed 15 polymorphisms of 12 genes in a population-based study in Korea (694 cases and 1700 controls). Four genotypes of DNA repair pathway genes (XRCC1 399 GA, OGG1 326 GG, BRCA1 871 TT, and WRN 787 TT) were associated with a decreased risk for NHL [odds ratio (OR)XRCC1 GA=0.80, p=0.02; OROGG1 GG=0.70, p=0.008; ORBRCA1 TT=0.71, p=0.048; ORWRN TT=0.68, p=0.01]. Conversely, the MGMT 115 CT genotype was associated with an increased risk for NHL (OR=1.25, p=0.04). In the MDR1 gene, the 1236 CC genotype was associated with a decreased risk for NHL (OR=0.74, p=0.04), and the 3435 CT and TT genotypes were associated with an increased risk (OR3435CT=1.50, p<0.0001; OR3435TT=1.43, p=0.02). These results suggest that polymorphisms in the DNA repair genes XRCC1, OGG1, BRCA1, WRN1, and MGMT and in the MDR1 gene may affect the risk for NHL in Korean patients.

Abstract
Diffuse large B-cell lymphoma (DLBCL) is a genetically heterogeneous neoplasm. Although several genetic and environmental factors have been postulated, no obvious risk factors have been emerged for DLBCL in the general population. DNA repair systems are responsible for maintaining the integrity of the genome and protecting it against genetic alterations that can lead to malignant transformation. The current study aimed at investigating the possible role of ERCC2/XPD Arg156Arg, Asp312Asn and Lys751Gln genetic polymorphisms as risk factors for DLBCL in Egypt. The study included 81 DLBCL patients and 100 healthy controls. Genotyping of the studied genetic polymorphisms was performed by polymerase chain reaction-restriction fragment length polymorphism technique. Our results revealed that there was no statistical difference encountered in the distribution of -Asp312Asn and -Lys751Gln polymorphic genotypes between DLBCL cases and controls, thus it could not considered as molecular risk factors for DLBCL in Egyptians. However, Arg156Arg polymorphism at exon-6 conferred twofold increased risk of DLBCL (OR 2.034, 95 %CI 1.015-4.35, p = 0.43), and the risk increased when co-inherited with Lys751Gln at exon-23 (OR 3.304, 95 %CI 1.113-9.812, p = 0.038). In conclusion, ERCC2/XPD Arg156Arg polymorphism might be considered as a genetic risk factor for DLBCL in Egyptians, whether alone or conjoined with Lys751Gln.

Abstract
The T241M polymorphism in the X-ray cross-complementing group 3 (XRCC3) had been implicated in cancer susceptibility. The previous published data on the association between XRCC3 T241M polymorphism and cancer risk remained controversial. Hence, we performed a meta-analysis to investigate the association between cancer susceptibility and XRCC3 T241M (61,861 cases and 84,584 controls from 157 studies) polymorphism in different inheritance models. We used odds ratios with 95% confidence intervals to assess the strength of the association. Overall, significantly increased cancer risk was observed in any genetic model (dominant model: odds ration [OR]=1.07, 95% confidence interval [CI]=1.00-1.13; recessive model: OR=1.15, 95% CI=1.08-1.23; additive model: OR=1.17, 95% CI=1.08-1.28) when all eligible studies were pooled into the meta-analysis. In further stratified and sensitivity analyses, the elevated risk remained for subgroups of bladder cancer and breast cancer, especially in Caucasians. In addition, significantly decreased lung cancer risk was also observed. In summary, this meta-analysis suggests the participation of XRCC3 T241M in the susceptibility for bladder cancer and breast cancer, especially in Caucasians, and XRCC3 T241M polymorphism is associated with decreased lung cancer risk. Moreover, our work also points out the importance of new studies for T241M association in some cancer types, such as gastric cancer, colorectal cancer, and melanoma skin cancer, where at least some of the covariates responsible for heterogeneity could be controlled, to obtain a more conclusive understanding about the function of the XRCC3 polymorphism in cancer development.

Abstract
The main objective of this study was to test the hypothesis that genetic variations in DNA repair genes may modify the association between occupational exposure to solvents and the risk of non-Hodgkin's lymphoma (NHL). A population-based case-control study was conducted on Connecticut women including 518 histologically confirmed incident NHL cases and 597 controls. Unconditional logistic regression models were used to estimate the odds ratios and effect modification from the 30 single nucleotide polymorphisms in 16 DNA repair genes of the association between solvent exposure and the risk of NHL overall and subtypes. Single nucleotide polymorphisms in MGMT (rs12917) and NBS1 (rs1805794) significantly modified the association between exposure to chlorinated solvents and the risk of NHL (Pfor interaction=0.0003 and 0.0048, respectively). After stratification by major NHL histological subtypes, MGMT (rs12917) modified the association between chlorinated solvents and the risk of diffuse large B-cell lymphoma (Pfor interaction=0.0027) and follicular lymphoma (Pfor interaction=0.0024). A significant interaction was also observed between occupational exposure to benzene and BRCA2 (rs144848) for NHL overall (Pfor interaction=0.0042). Our study results suggest that genetic variations in DNA repair genes modify the association between occupational exposure to solvents and the risk of NHL.

Abstract
The purpose of the study was to investigate the possible association between ERCC2 rs28365048, ERCC5 rs17655, XRCC3 rs861539 and NOS2A rs2297518 polymorphisms with B-cell lymphoma. The study was conducted on 189 patients with CD20+ B-cell lymphoma and 193 controls. The genotype frequencies were compared in the patient and control groups using quantitative polymerase chain reaction, based on allelic discrimination analysis. Our results indicated that variation in NOS2A may be significant in B-cell lymphoma in a population ≥50 years old (OR=2.15; 95% CI, 1.17-3.92; P=0.013). No association was observed between variations in ERCC2, ERCC5, XRCC3 and B-cell lymphoma in the studied population. Our finding of an association between age and NOS2A polymorphisms in lymphoma is unique and requires additional studies. The results concerning ERCC2, ERCC5 and XRCC3 variations add additional data to studies on genetic polymorphisms in the DNA repair pathway.

Abstract
Follicular lymphoma (FL) is an indolent malignancy of germinal center B cells with varied incidence across racial groups and geographic regions. Improvements in the classification of non-Hodgkin lymphoma subtypes provide an opportunity to explore associations between environmental exposures and FL incidence. Our paper found that aspects of Western lifestyle including sedentary lifestyle, obesity, and diets high in meat and milk are associated with an increased risk of FL. Diets rich in fruits and vegetables, polyunsaturated fatty acids, vitamin D, and certain antioxidants are inversely associated with FL risk. A medical history of Sjogren's syndrome, influenza vaccination, and heart disease may be associated with FL incidence. Associations between FL and exposure to pesticides, industrial solvents, hair dyes, and alcohol/tobacco were inconsistent. Genetic risk factors include variants at the 6p21.32 region of the MHC II locus, polymorphisms of the DNA repair gene XRCC3, and UV exposure in individuals with certain polymorphisms of the vitamin D receptor. Increasing our understanding of risk factors for FL must involve integrating epidemiological studies of genetics and exposures to allow for the examination of risk factors and interactions between genes and environment.

Abstract
OBJECTIVE This study aims to investigate the association between the polymorphisms in DNA repair genes (XPD, XRCC1, and XRCC4) and clinical parameters in patients with multiple myeloma (MM), their effects on prognosis and their roles in susceptibility to MM. PATIENTS AND METHODS Sixty patients, diagnosed with MM and 70 individuals as the healthy control group were included in the study. Gene polymorphisms were detected with the polymerase chain reaction and/or polymerase chain reaction-restriction fragment length polymorphism method. When the genotype frequencies of XPD (Llys751Gln) and XRCC1 (Arg399Gln) genes were examined in the patient and control groups, no significant difference was detected, while a significant association was found in XRCC4 (VNTR in intron 3 and G-1394T) polymorphisms. A significant association was found in the MM patients group for AA genotype and event-free survival (EFS) in terms of XPD (751) gene polymorphism (P = 0.047). When VNTR intron 3 polymorphism was compared for genotype frequency, DD genotype was found to be significantly low (P = 0.012) in the patient group, whereas GG and TT genotypes were found to be significantly lower in the patient group for the genotype frequency XRCC4 (G-1394T) polymorphism when compared to the control group (P = 0.015, P = 0.010, respectively). RESULTS These data provide support for the hypothesis that a common variation in the genes encoding XRCC4 DNA repair proteins may contribute to susceptibility to myeloma. These findings require further validation in independent populations.

Abstract
The role of inherited (host) genetic susceptibility in the pathogenesis of follicular lymphoma (FL) is reviewed. First degree relatives of FL patients are at an increased risk of FL, suggesting a role for inherited factors. While there have been no linkage studies in FL families, candidate gene and genome-wide association studies have identified several risk loci which have been confirmed in independent studies. These include regions on 6p21.32-33 and TNF family members. Host genetics has also been hypothesized to influence treatment response, disease progression and overall survival. Early leads in FL prognosis include pathways that regulate immune function, antibody-dependent cellular cytotoxicity, chemotaxis, and one-carbon metabolism, although few of these associations have been independently confirmed. While the use of host genetics to identify individuals at high risk of FL or to predict FL treatment response and prognosis appears to be very promising, it is not yet ready for the clinic.

Abstract
Follicular lymphoma (FL) is one of the most common Non-Hodgkin lymphoma (NHL) subtype. Only small number of studies concerning NHL and DNA reparation gene polymorphisms has been performed so far. Hence, we have assessed the effect of 4 selected polymorphisms with possible influence on risk of FL development in a case-control study in Slovak population. We have genotyped polymorphisms in the RAG1 (K820R), LIG4 (T9I), BRCA2 (N372H), and WRN (V114I) genes in 108 patients with histologically proven FL diagnosis and 127 healthy controls. For discrimination between the allelic variants, we have established the genotyping by real-time melting analysis of an unlabeled probe. The most notable finding was related to polymorphism N372H in the BRCA2 gene. Compared with the wild-type genotype (NN), the homozygous variant genotype (HH) was associated with an increased FL risk (OR = 2.91, 95% CI: 0.96-8.81), although on the borderline of statistical significance (P = 0.050). However, after stratification by gender and age, the FL risk was significantly increased in men with variant-containing genotypes (OR = 2.79, 95% CI: 1.20-6.45) and even severalfold significantly increased among men with homozygous variant BRCA2 genotype (OR = 21.18, 95% CI: 2.46-182.2). No significant associations with FL risk were identified for other polymorphisms.

Abstract
OBJECTIVE The impact of single-nucleotide polymorphisms (SNPs) on tumour susceptibility and pathogenesis has gained enormous attention. Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS)-based genotyping facilitates the analysis of short DNA amplicons and is, therefore, a promising tool for the investigation of formalin-fixed paraffin-embedded (FFPE) tissue samples, particularly in targeted genotyping analysis. METHODS To examine the applicability of genotyping FFPE DNA with MALDI-TOF MS in multiplex reactions, we investigated five DNA samples extracted from FFPE tumour specimens from follicular lymphoma patients using different extraction methods (phenol-chloroform, commercial kit). Thirty-one SNPs from 25 genes, integrated in different-sized multiplex assays (7-plex, 10-plex, 14-plex, 24-plex), were analyzed. To investigate the reliability of genotyping tumour-derived DNA extracted from FFPE tissue, we examined 64 FFPE tumour specimens in comparison with matched germline DNA samples. RESULTS Call rates of 99.6 (274/275) and 93.5% (257/275) were observed for the DNA extracted with the phenol-chloroform approach or the commercial extraction kit, respectively. Increasing the number of SNPs per assay resulted in reduced genotyping call rates and genotyping quality, especially in the DNA samples isolated with the commercial extraction kit. When comparing the genotypes of DNA derived from germline and tumour (FFPE) specimens, a perfect concordance rate of 100% was detected. CONCLUSION Our data delineate that MALDI-TOF-based genotyping of FFPE DNA is reliable and reproducible even in multiplex reactions, enabling the retrospective investigation of FFPE study cohorts in future experiments.

Abstract
BACKGROUND When the case-only study design is used to estimate statistical interaction between genetic (G) and environmental (E) exposures, G and E must be independent in the underlying population, or the case-only estimate of interaction (COR) will be biased. Few studies have examined the occurrence of G-E association in published control group data. METHODS To examine the assumption of G-E independence in empirical data, we conducted a systematic review and meta-analysis of G-E associations in controls for frequently investigated DNA repair genes (XRCC1 Arg399Gln, Arg194Trp, or Arg280His, XPD Lys751Gln, and Asp312Asn, and XRCC3 Thr241Met), and smoking (ever/never smoking, current/not current smoker, smoking duration, smoking intensity, and pack-years). RESULTS Across the 55 included studies, single nucleotide polymorphisms SNP-smoking associations in controls (OR(z)) were not reliably at the null value of 1.0 for any SNP-smoking combinations. Two G-E combinations were too heterogeneous for summary estimates: XRCC1 399 and ever-never smoking (N = 21), and XPD 751 and pack-years (N = 12). OR(z) ranges for these combinations were: [OR(z) (95% confidence interval (CI)] 0.7 (0.4, 1.2)-1.9 (1.2, 2.8) and 0.8 (0.5, 1.3)-2.3 (0.8, 6.1), respectively). Estimates for studies considered homogeneous (Cochran's Q P-value <0.10) varied 2- to 5-fold. No study characteristics were identified that could explain heterogeneity. CONCLUSIONS We recommend the independence assumption be evaluated in the population underlying any potential case-only study, rather than in a proxy control group(s) or pooled controls. IMPACT These results suggest that G-E association in controls may be population-specific. Increased access to control data would improve evaluation of the independence assumption.

A new method to detect loss of heterozygosity using cohort heterozygosity comparisons. BMC Cancer 2010; 10:195.

Abstract
BACKGROUND Loss of heterozygosity (LOH) is an important marker for one of the 'two-hits' required for tumor suppressor gene inactivation. Traditional methods for mapping LOH regions require the comparison of both tumor and patient-matched normal DNA samples. However, for many archival samples, patient-matched normal DNA is not available leading to the under-utilization of this important resource in LOH studies. Here we describe a new method for LOH analysis that relies on the genome-wide comparison of heterozygosity of single nucleotide polymorphisms (SNPs) between cohorts of cases and un-matched healthy control samples. Regions of LOH are defined by consistent decreases in heterozygosity across a genetic region in the case cohort compared to the control cohort. METHODS DNA was collected from 20 Follicular Lymphoma (FL) tumor samples, 20 Diffuse Large B-cell Lymphoma (DLBCL) tumor samples, neoplastic B-cells of 10 B-cell Chronic Lymphocytic Leukemia (B-CLL) patients and Buccal cell samples matched to 4 of these B-CLL patients. The cohort heterozygosity comparison method was developed and validated using LOH derived in a small cohort of B-CLL by traditional comparisons of tumor and normal DNA samples, and compared to the only alternative method for LOH analysis without patient matched controls. LOH candidate regions were then generated for enlarged cohorts of B-CLL, FL and DLBCL samples using our cohort heterozygosity comparison method in order to evaluate potential LOH candidate regions in these non-Hodgkin's lymphoma tumor subtypes. RESULTS Using a small cohort of B-CLL samples with patient-matched normal DNA we have validated the utility of this method and shown that it displays more accuracy and sensitivity in detecting LOH candidate regions compared to the only alternative method, the Hidden Markov Model (HMM) method. Subsequently, using B-CLL, FL and DLBCL tumor samples we have utilised cohort heterozygosity comparisons to localise LOH candidate regions in these subtypes of non-Hodgkin's lymphoma. Detected LOH regions included both previously described regions of LOH as well as novel genomic candidate regions. CONCLUSIONS We have proven the efficacy of the use of cohort heterozygosity comparisons for genome-wide mapping of LOH and shown it to be in many ways superior to the HMM method. Additionally, the use of this method to analyse SNP microarray data from 3 common forms of non-Hodgkin's lymphoma yielded interesting tumor suppressor gene candidates, including the ETV3 gene that was highlighted in both B-CLL and FL.

Abstract
Non-Hodgkin lymphoma (NHL) represents a complex group of B- and T-cell malignancies characterised by chromosomal translocations. Since defects in DNA repair result in an increased frequency of chromosomal aberrations it has been hypothesised that genetic variation in DNA repair may be associated with risk of NHL. To investigate the relationship between DNA repair and NHL we analysed polymorphisms in XPD (R156R, D312N, K751Q) using DNA collected in a UK population-based case-control study of lymphoma. We observed no association between genetic variation in XPD and risk of NHL. However, the XPD 751 Gln allele was associated with a two-fold decreased risk of diffuse large B-cell lymphoma (OR 0.56, 95% CI 0.34-0.92, p=0.02), the major subtype of NHL. Overall, our study identifies that XPD polymorphisms may be important in the aetiology of NHL although analysis of additional polymorphisms and extended haplotype studies are required to clarify their role.

Abstract
OBJECTIVES The authors evaluated the possible effect of DNA repair genes, XPD (Xeroderma pigmentosum group D) codon (312 and 751) and XRCC1 (X-ray repair cross-complementing group 1) codon (194 and 399) SNPs (single-nucleotide polymorphisms) on the risk of childhood B-cell lymphoma. METHODS The polymorphisms were analyzed in 33 patients with BL cases and in 52 healthy, age-matched controls using PCR-RFLP method. RESULTS The authors observed no association between variation in the XPD codon Asp312Asn, Lys751Gln, and XRCC1 codon Arg399Gln polymorphisms and B-cell lymphoma for any parameter. In contrast, tryptophan allele frequency in control and patient groups was 0.10 and 0.03 respectively (p = .04). The frequency of XRCC1 194Arg/Trp genotype in B-cell lymphoma was significantly lower than that in controls (p = .005). No significant relationship was found between genotypes and stage, lactate dehydrogenase, or bone marrow involvement. CONCLUSIONS XRCC1 194Trp allele may be associated with a protective effect against development of childhood B-cell lymphoma. However, these results were based on a small number of case and further studies should be done.

Abstract
Genetic polymorphism in DNA repair genes may influence individual variation in DNA repair capacity, which may be associated with cancer risks. This hospital-based case-control study examined whether polymorphism in the DNA repair gene x-ray repair cross-complementing groups 1 (XRCC1 Arg194Trp [C-->T], Arg280His [G-->A], and Arg399Gln [G-->A]) played a role in susceptibility to non-Hodgkin's lymphoma (NHL) in the Chinese population. We genotyped these polymorphisms for 221 histopathologically confirmed NHL cases and 254 age- and sex-matched healthy control cases in China. No studied polymorphism alone was shown to be related to the risk of NHL or each histologic subtype of NHL. When stratified by smoking status, however, the XRCC1Arg399Gln variant genotypes (homozygotes and heterozygotes) were associated with a 3.0-fold risk of follicular lymphoma among heavy smokers (95% confidence interval: 1.16-7.82; P = 0.02). Further large-scale studies would confirm this association and clarify marginally significant trends in XRCC1 polymorphism combinations for an increased risk for NHL.

Abstract
BACKGROUND Although the pathogenesis of Hodgkin disease (HD) remains unknown, the results of epidemiologic studies suggest that heritable factors are important in terms of susceptibility. Polymorphisms in DNA repair genes may contribute to individual susceptibility for development of different cancers. However, to the authors' knowledge, few studies to date have investigated the role of such polymorphisms as risk factors for development of HD. METHODS The authors evaluated the relation between polymorphisms in 3 nucleotide excision repair pathway genes (XPD [Lys751Gln], XPC [Lys939Gln], and XPG [Asp1104His]), the base excision repair XRCC1 (Arg399Gln), and double-strand break repair XRCC3 (Thr241Met) in a population of 200 HD cases and 220 matched controls. Variants were investigated independently and in combination; odd ratios (OR) were calculated. RESULTS A positive association was found for XRCC1 gene polymorphism Arg399Gln (OR, 1.77; 95% confidence interval [95% CI], 1.16-2.71) and risk of HD. The combined analysis demonstrated that XRCC1/XRCC3 and XRCC1/XPC polymorphisms were associated with a significant increase in HD risk. XRCC1 Arg/Arg and XRCC3 Thr/Met genotypes combined were associated with an OR of 2.38 (95% CI, 1.24-4.55). The XRCC1 Arg/Gln and XRCC3 Thr/Thr, Thr/Met, and Met/Met genotypes had ORs of 1.88 (95% CI, 1.02-4.10), 1.97 (95% CI, 1.05-3.73), and 4.13 (95% CI, 1.50-11.33), respectively. XRCC1 Gln/Gln and XRCC3 Thr/Thr variant led to a significant increase in risk, with ORs of 3.00 (95% CI, 1.15-7.80). Similarly, XRCC1 Arg/Gln together with XPC Lys/Lys was found to significantly increase the risk of HD (OR, 2.14; 95% CI, 1.09-4.23). CONCLUSIONS These data suggest that genetic polymorphisms in DNA repair genes may modify the risk of HD, especially when interactions between the pathways are considered.

Abstract
Many studies have suggested that adenosine diphosphate ribosyl transferase (ADPRT), X-ray repair cross-complementing 1 (XRCC1), and xeroderma pigmentosum complementary group D (XPD) are three major DNA base excision repair (BER) genes and that they act interactively in stimulating and executing BER processes. Polymorphisms of these genes may influence the rate of gene transcription, the stability of the messenger RNA, or the quantity and activity of the resulting protein. Thus, the susceptibility or severity of several disorders is influenced by possession of specific alleles of polymorphic genes. So, it is plausible that variations and mutations in these genes affect DNA repair capacity in normal populations, and thus facilitate cancer development in normal or exposed individuals. To promote translation of scientific findings for potential clinical application of DNA repair function, we have searched publications relevant to molecular epidemiology studies of associations between single-nucleotide polymorphisms (SNPs) in the genes, and several frequent human cancer. We have focused on five particular polymorphisms as our starting point: the T-->C polymorphism (Val762Ala) in exon 17 of ADPRT, the novel transition at the promoter region (-77T-->C) of XRCC1, two common nonsynonymous polymorphisms (Arg194Trp and Arg399Gln), and the C-->A silent polymorphism (Arg156Arg) in exon 6 of XPD. We review here the case-control studies examining whether these polymorphisms are correlated with reduced DNA repair efficiency, their influence on the development of different solid tumors, and their possible interactions with other genetic factors and environmental exposures.

Abstract
The objective of this study was to determine whether an association exists between certain single nucleotide polymorphisms (SNPs), which have previously been linked with adverse normal tissue effects resulting from radiotherapy, and the development of radiation injury resulting from radiotherapy for prostate cancer. A total of 135 consecutive patients with clinically localized prostate cancer and a minimum of 1 year of follow-up who had been treated with radiation therapy, either brachytherapy alone or in combination with external-beam radiotherapy, with or without hormone therapy, were genotyped for SNPs in SOD2, XRCC1 and XRCC3. Three common late tissue toxicities were investigated: late rectal bleeding, urinary morbidity, and erectile dysfunction. Patients with the XRCC1 rs25489 G/A (Arg280His) genotype were more likely to develop erectile dysfunction after irradiation than patients who had the G/G genotype (67% compared to 24%; P=0.048). In addition, patients who had the SOD2 rs4880 T/C (Val16Ala) genotype exhibited a significant increase in grade 2 late rectal bleeding compared to patients who had either the C/C or T/T genotype for this SNP (8% compared to 0%; P=0.02). Finally, patients with the combination of the SOD2 rs4880 C/T genotype and XRCC3 rs861539 T/C (Thr241Met) genotype experienced a significant increase in grade 2 late rectal bleeding compared to patients without this particular genotypic arrangement (14% compared to 1%; P=0.002). These results suggest that SNPs in the SOD2, XRCC1 and XRCC3 genes are associated with the development of late radiation injury in patients treated with radiation therapy for prostate adenocarcinoma.

Abstract
Genetic susceptibility to DNA oxidation, carcinogen metabolism, and altered DNA repair may increase non-Hodgkin lymphoma (NHL) risk, whereas vegetables- and antioxidant-related nutrients may decrease risk. We evaluated the interaction of a priori-defined dietary factors with 28 polymorphisms in these metabolic pathways. Incident cases (n = 1,141) were identified during 1998-2000 from four cancer registries and frequency-matched to population-based controls (n = 949). We estimated diet-gene joint effects using two-phase semi-parametric maximum-likelihood methods, which utilized genotype data from all subjects as well as 371 cases and 311 controls with available diet information. Adjusted odds ratios (95% confidence intervals) were lower among common allele carriers with higher dietary intakes. For the GSTM3 3-base insertion and higher total vegetable intake, the risk was 0.56 (0.35-0.92, p interaction = 0.03); for GSTP1 A114V and higher cruciferous vegetable intake, the risk was 0.52 (0.34-0.81, p interaction = 0.02); for OGG1 S326C and higher daily zinc intake, the risk was 0.71 (0.47-1.08, p interaction = 0.04) and for XRCC3 T241M and higher green leafy vegetable intake, the risk was 0.63 (0.41-0.97, p interaction = 0.03). Calculation of the false positive report probability determined a high likelihood of falsely positive associations. Although most associations have not been examined previously with NHL, our results suggest the examined polymorphisms are not modifiers of the association between vegetable and zinc intakes and NHL risk.

Abstract
Genetic susceptibility studies of lymphoma may serve to identify at risk populations and clarify important disease mechanisms. This review considered all studies published through October 2006 on the contribution of genetic polymorphisms in the risk of lymphoma. Numerous studies implicate the role of genetic variants that promote B-cell survival and growth with increased risk of lymphoma. Several reports including a large pooled study by InterLymph, an international consortium of non-Hodgkin lymphoma (NHL) case-control studies, found positive associations between variant alleles in TNF -308G>A and IL10 -3575T>A genes and risk of diffuse large B-cell lymphoma. Four studies reported positive associations between a GSTT1 deletion and risk of Hodgkin and non-Hodgkin lymphoma. Genetic studies of folate-metabolizing genes implicate folate in NHL risk, but further studies that include folate and alcohol intakes are needed. Links between NHL and genes involved in energy regulation and hormone production and metabolism may provide insights into novel mechanisms implicating neuro- and endocrine-immune cross-talk with lymphomagenesis. However, this links will need replication in larger populations. Numerous studies suggest that common genetic variants with low penetrance influence lymphoma risk, though replication studies will be needed to eliminate false positive associations.

Abstract
To evaluate the effect of DNA repair gene XRCC1 polymorphisms on the risk of lung cancer in a northeastern Chinese population, we studied five cSNPs in the XRCC1 gene, three that lead to non-synonymous changes: Arg194Trp, Arg280 His and Arg399Gln and two that lead to synonymous changes: Pro206Pro and Gln632Gln. A hospital-based case-control study consisted of 247 lung cancer cases and 253 cancer-free controls matched on age, gender and ethnicity. PCR-RFLP was used for genotyping. Carriers of the minor G-allele of Pro206Pro were at significantly increased risk of lung cancer (adjusted OR=1.96, 95% CI=1.26-3.06, P=0.003). Stratified analyses revealed a significantly decreased risk of lung cancer associated with the AG/AA genotype of Arg280His (AG+AA versus GG, OR=0.38, 95% CI=0.19-0.75, P=0.005) among never smokers, although there was no interaction between Arg280His and smoking. In a haplotype analysis, a haplotype defined by Arg194Trp(C)-Pro206Pro(G)-Arg280His(G)-Arg399Gln(G)-Gln632Gln(G) was associated with increased risk of lung cancer (OR=28.60, 95% CI=2.49-331.31, P=4.45x10(-5)). No associations were observed for the other polymorphisms or haplotypes. Our results suggest that the XRCC1 Pro206Pro polymorphism or the haplotype encompassing the minor allele may contribute to genetic susceptibility for lung cancer in this northeastern Chinese population. To our knowledge, this is first report that XRCC1 Pro206Pro influences cancer risk.

Abstract
Chromosomal translocations, insertions, and deletions are common early events in non-Hodgkin lymphoma (NHL) carcinogenesis, and implicated in their formation are endogenous processes involved in antigen-receptor diversification, such as V(D)J recombination. DNA repair genes respond to the double- and single-strand breaks induced by these processes and may influence NHL etiology. We examined 34 genetic variants in 19 genes within or related to 5 DNA repair pathways among 1172 cases and 982 matched controls who participated in a population-based NHL study in Los Angeles, Seattle, Detroit, and Iowa from 1998 to 2000. Cases were more likely than controls to have the RAG1 820 R/R (odds ratio [OR] = 2.7; 95% confidence interval [CI] = 1.4 to 5.0) than Lys/Lys genotypes, with evidence of a gene dosage effect (P trend < .001), and less likely to have the LIG4 (DNA ligase IV) 9 Ile/Ile (OR = 0.5; 95% CI = 0.3 to 0.9) than T/T genotype (P trend = .03) in the nonhomologous end joining (NHEJ)/V(D)J pathway. These NHEJ/V(D)J-related gene variants represent promising candidates for further studies of NHL etiology and require replication in other studies.

Abstract
The X-ray repair cross-complementing group 3 (XRCC3) is a highly suspected candidate gene for cancer susceptibility. However, association studies on the XRCC3 polymorphisms (4541A>G, Thr(241)Met, 17893A>G) in cancer have shown conflicting results. Therefore, we performed a meta-analysis to better assess the purported associations. Forty eight eligible case-control studies including 24,975 cancer patients and 34, 209 controls were selected for our meta-analysis. Overall, individuals carrying the XRCC3 Met/Met genotype showed a small cancer risk under a recessive genetic model. The subgroup and meta-regression analysis demonstrated different scenarios concerning the XRCC3 Met/Met genotype's role in cancer susceptibility for different subgroups. Specially, there was a significantly increased risk of breast cancer (OR, 1.14; P=0.0004; 95% CI, 1.06-1.23; P=0.37 for heterogeneity), elevated but not significant risk of cancer for head and neck, bladder, surprisingly, a significantly decreased risk of non-melanoma skin cancer (OR, 0.76; P=0.007; 95% CI, 0.62-0.93; P=0.61 for heterogeneity). A significantly elevated risk of cancer was observed in population-based case-control studies but not in nested or hospital based studies. Similarly, we found a significantly increased risk of cancer for A4541G and a decreased risk for A17893G under dominant genetic models. Our meta-analysis results support that the XRCC3 might represent a low-penetrance susceptible gene especially for cancer of breast, bladder, head and neck, and non-melanoma skin cancer. A single larger study should be required to further evaluate gene-gene and gene-environment interactions on XRCC3 polymorphisms and tissue-specific cancer risk in an ethnicity specific population.
