Abstract
Over the past decades, it is recognized that loss of DNA damage repair (DDR) pathways is an early and frequent event in tumorigenesis, occurring in 40-50% of many cancer types. The basis of synthetic lethality in cancer therapy is DDR deficient cancers dependent on backup DNA repair pathways. In cancer, the concept of synthetic lethality has been extended to pairs of genes, in which inactivation of one by deletion or mutation and pharmacological inhibition of the other leads to death of cancer cells whereas normal cells are spared the effect of the drug. The paradigm study is to induce cell death by inhibiting PARP in BRCA1/2 defective cells. Since the successful application of PARP inhibitor, a growing number of developed DDR inhibitors are ongoing in preclinical and clinical testing, including ATM, ATR, CHK1/2 and WEE1 inhibitors. Combination of PARP inhibitors and other DDR inhibitors, or combination of multiple components of the same pathway may have great potential synthetic lethality efficiency. As epigenetics joins Knudson’s two hit theory, silencing of DDR genes by aberrant epigenetic changes provide new opportunities for synthetic lethal therapy in cancer. Understanding the causative epigenetic changes of loss-of-function has led to the development of novel therapeutic agents in cancer. DDR and related genes were found frequently methylated in human cancers, including BRCA1/2, MGMT, WRN, MLH1, CHFR, P16 and APC. Both genetic and epigenetic alterations may serve as synthetic lethal therapeutic markers.

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.

Interaction of XRCC1 Arg399Gln Polymorphism and Alcohol Consumption Influences Susceptibility of Esophageal Cancer. Gastroenterol Res Pract 2016; 2016:9495417. [PMID: 26949387 PMCID: PMC4753333 DOI: 10.1155/2016/9495417] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/06/2015] [Revised: 12/16/2015] [Accepted: 12/28/2015] [Indexed: 12/31/2022] Open
Abstract
Background. To explore the correlation between the Arg399Gln polymorphism and susceptibility to esophageal cancer in Korean and Han Chinese individuals in Harbin, China, and its potential interaction with alcohol consumption. Methods. This prospective study included 203 patients with esophageal squamous cell carcinoma; 88 were of Korean descent and 115 were of Han Chinese descent. A group of healthy controls included 105 participants of Korean descent and 105 of Han Chinese descent. Genotyping of the Arg399Gln locus of XRCC1 was performed by PCR-RFLP. Results. The allelic and genotypic frequencies were not significantly different between individuals with esophageal cancer and controls or between individuals of Korean and Han Chinese descent (P > 0.05). However, when individuals with the wild-type Arg/Arg genotype also consumed alcohol, the risk of esophageal cancer was lower (OR = 3.539; 95% CI = 2.039-6.142; P < 0.05). Conclusions. The XRCC1 Arg399Gln polymorphism does not appear to be associated with esophageal cancer in individuals of Korean or Han Chinese descent in Harbin, China. However, alcohol consumption may decrease the risk of esophageal cancer in persons with the wild-type genotype.

Association of the XPD and XRCC3 gene polymorphisms with oral squamous cell carcinoma in a Northeastern Brazilian population: A pilot study. Arch Oral Biol 2015; 64:19-23. [PMID: 26742000 DOI: 10.1016/j.archoralbio.2015.12.004] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/13/2015] [Revised: 10/06/2015] [Accepted: 12/19/2015] [Indexed: 10/22/2022]
Abstract
OBJECTIVE to evaluate the association between XPD and XRCC3 polymorphisms and oral squamous cell carcinoma (OSCC). DESIGN the sample consisted of 54 cases of OSCC and 40 cases of inflammatory fibrous hyperplasia (IFH). Genotypes were determined by the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method. RESULTS XPD-Lys/Gln was more common in IFH (n=28; 70%) than in OSCC (n=24; 44.4%) (OR: 0.3; p<0.05). XPD-Gln was more frequent in high-grade lesions (0.48) than in low-grade lesions (0.21) (OR: 3.4; p<0.05). The Gln/Gln genotype was associated with III and IV clinical stages (OR: 0.07; p<0.05). XRCC3-Met was more frequent in OSCC (0.49) than in IFH (0.35) (OR: 2.6; p<0.05). The Met/Met genotype was associated with the presence of metastases (OR: 8.1; p<0.05) and with III and IV clinical stages (OR: 0.07; p<0.05). CONCLUSIONS in this sample, the frequency of XPD-Gln in IFH suggests that this variant may protect against OSCC. The presence of the XRCC3-Met allele seems to contribute to the development of OSCC, metastases and more advanced stages in these lesions.

Abstract
OBJECTIVES To investigate the association between three single nucleotide polymorphisms (SNPs) in the X-ray repair cross complementing 1 gene (XRCC1) and the risk of esophageal squamous cell carcinoma (ESCC) in Chinese population. METHODS A case-control study including 381 primary ESCC patients recruited from hospital and 432 normal controls matched with patients by age and gender from Chinese Han population was conducted. The genotypes of three XRCC1 polymorphisms at -77T>C (T-77C), codon 194 (Arg194Trp), and codon 399 (Arg399Gln) were studied by means of polymerase chain reaction-restriction fragment length polymorphism techniques (PCR-RFLP). Unconditional logistic regression model and haplotype analysis were used to estimate associations of these three SNPs in XRCC1 gene with ESCC risk. RESULTS Polymorphisms at these three sites in XRCC1 gene were not found to be associated with risk for developing ESCC; however the haplotype C(codon 194)G(codon 399)C(-77T>C) was significantly associated with reduced risk of ESCC (OR: 0.62, 95% CI: 0.40-0.96) upon haplotype analysis. CONCLUSION These results suggested that the gene-gene interactions might play vital roles in the progression on esophageal cancer in Chinese Han population and it would be necessary to confirm these findings in a large and multiethnic population.

Abstract
OBJECTIVE Published data regarding the association between xeroderma pigmentosum group D XPD Lys751Gln polymorphisms and esophageal cancer (EC) cancer remain controversial. The present meta-analysis aimed to obtain a more precise estimation of the relationship between XPD Lys751Gln polymorphisms and the risk of EC. METHODS All eligible case-control studies of Lys751Gln polymorphisms and susceptibility to EC were selected from PubMed, Web of Science and CNKI up to October 2013. The data were extracted, and pooled odds ratios (ORs) with 95% confidence intervals (CIs) were calculated. RESULTS A total of 21 case-control studies from 19 reports were assessed in this meta-analysis, including 6,581 cases and 8,251 controls. There was a significant association between the XPD Lys751Gln polymorphism and the risk of esophageal cancer in the overall population (Dominant model: OR=1.30, 95%CI: 1.07-1.57, p<0.05; Lys/Gln vs. Gln/Gln: OR=1.20, 95%CI: 1.05-137, p<0.05; Gln/Gln vs. Lys/Lys: OR=1.76, 95%CI: 1.08-2.85, p=0.02; Recessive model: OR=1.48, 95%CI: 1.06-2.07, p=0.02). Similar results were found when stratified according to the cancer type, ethnicity and control source. However, no associations were found among smokers or drinkers. CONCLUSION The results of this meta-analysis suggest that XPD Lys751Gln polymorphisms contribute to susceptibility to EC.

Abstract
Published data regarding the association between the excision repair cross-complimentary group 2 (ERCC2) Asp312Asn polymorphisms and esophageal cancer susceptibility remained controversial. This meta-analysis of literatures was performed to assess the strength of association between the ERCC2 and esophageal cancer susceptibility using random effects model. We systematically searched PubMed, Embase and Web of Science with a time limit of September 15, 2013. Summary odds ratios (ORs) with 95 % confidence intervals (CIs) were used to assess the strength of association between the ERCC2 Asp312Asn polymorphism and esophageal cancer susceptibility using random effects model. A total of seven case-control studies including 1,831 cases and 2,728 controls were included for analysis. Overall, a significant association was found between ERCC2 Asp312Asn polymorphism and esophageal cancer susceptibility for GA vs. GG (OR = 1.20, 95 % CI = 1.03-1.40) and for the dominant model GA/AA vs. GG (OR = 1.18, 95 % CI = 1.03-1.35). However, the ERCC2 Asp312Asn polymorphism was a protective factor for AA vs. GA/GG (OR = 0.63, 95 % CI = 1.15-2.65) in esophageal squamous cell carcinoma. Our meta-analysis suggested that the ERCC2 Asp312Asn polymorphism might be associated with increased risk of esophageal adenocarcinoma and a protective factor for esophageal squamous cell carcinoma.

Abstract
Background The Xeroderma pigmento-sum group D gene (XPD) plays a key role in nucleotide excision repair. Single nucleotide polymorphisms (SNP) located in its functional region may alter DNA repair capacity phenotype and cancer risk. Many studies have demonstrated that XPD polymorphisms are significantly associated with digestive tract cancers risk, but the results are inconsistent. We conducted a comprehensive meta-analysis to assess the association between XPD Lys751Gln polymorphism and digestive tract cancers risk. The digestive tract cancers that our study referred to, includes oral cancer, esophageal cancer, gastric cancer and colorectal cancer. Methods We searched PubMed and EmBase up to December 31, 2012 to identify eligible studies. A total of 37 case-control studies including 9027 cases and 16072 controls were involved in this meta-analysis. Statistical analyses were performed with Stata software (version 11.0, USA). Odds ratios (ORs) with 95% confidence intervals (CIs) were used to assess the strength of the association. Results The results showed that XPD Lys751Gln polymorphism was associated with the increased risk of digestive tract cancers (homozygote comparison (GlnGln vs. LysLys): OR = 1.12, 95% CI = 1.01–1.24, P = 0.029, Pheterogeneity = 0.133). We found no statistical evidence for a significantly increased digestive tract cancers risk in the other genetic models. In the subgroup analysis, we also found the homozygote comparison increased the susceptibility of Asian population (OR = 1.28, 95% CI = 1.01–1.63, P = 0.045, Pheterogeneity = 0.287). Stratified by cancer type and source of control, no significantly increased cancer risk was found in these subgroups. Additionally, risk estimates from hospital-based studies and esophageal studies were heterogeneous. Conclusions Our meta-analysis suggested that the XPD 751Gln/Gln genotype was a low-penetrate risk factor for developing digestive tract cancers, especially in Asian populations.

Abstract
Esophageal squamous cell carcinoma (ESCC), one of the leading causes of cancer death worldwide, occurs at a relatively high frequency in China. To investigate whether common excision repair cross-complementing rodent repair group 2 (ERCC2) variants (rs3916874 G>C, rs238415 C>G, rs1618536 G>A, rs1799793 G>A, and rsl3181 A>C) were associated with ESCC risk, a case-control study was conducted, including 405 cases with ESCC and 405 age and sex 1:1 matched cancer-free controls. The result showed that rsl3181 AC/CC genotypes was associated with an increased risk of ESCC (OR: 1.45, 95% CI: 1.05-2.00), and two ERCC2 haplotypes Grs3916874Crs238415Grs1618536Grs1799793Crsl3181 (Hap5) and Grs3916874Grs238415Ars1618536Grs1799793Crsl3181 (Hap7) were associated with increased risk of ESCC (OR: 2.16, 95 % CI: 1.27-3.57 for Hap5 and OR: 3.72; 95 % CI: 1.89-6.63 for Hap7, respectively), while Grs3916874Grs238415Grs1618536Grs1799793Arsl3181 (Hap4) was associated with decreased risk of ESCC (OR: 0.47, 95% CI: 0.35-0.71). Gene-environment interaction analysis by multifactor dimensionality reduction (MDR) software showed that there was an interaction among rs238415, rs1618536, and family history of cancer with a P value under 0.0001 (OR: 3.23: 95% CI: 2.37-4.40). These results suggested that genetic variations in the ERCC2 gene were associated with risk of ESCC, and there was a significant interaction between gene polymorphisms and family history of cancer in the etiology of ESCC.

Abstract
Esophageal cancer (EC) is a common malignancy worldwide. The X-ray repair cross-complementing 1 gene (XRCC1) is one of the most important candidate genes for influencing susceptibility to EC. This study aimed to investigate the effect of XRCC1 genetic variants on susceptibility to EC. A total of 383 EC patients (males: 239, females: 144, mean age: 56.62) and 387 cancer-free controls (males: 251, females: 136, mean age: 58.23) were enrolled in this study. The c.910A>G genetic variant of the XRCC1 gene was determined by polymerase chain reaction-restriction fragment length polymorphism and DNA sequencing methods. The allele and genotype frequencies indicated statistical differences between EC patients and cancer-free controls. The c.910A>G genetic variant was statistically associated with increased susceptibility to EC [GG vs AA: odds ratio (OR)=1.79, 95% confidence interval (CI)=1.12-2.86, P=0.014; GG vs AG/AA: OR=1.76, 95%CI=1.13-2.75, P=0.013; G vs A: OR=1.25, 95%CI=1.01-1.55, P=0.041]. The allele G and genotype GG could contribute to the increased susceptibility to EC. Our findings suggest that the c.910A>G genetic variant is associated with susceptibility to EC in the Chinese Han population, and might be used as a molecular marker for detecting susceptibility to EC.

Dig Dis Sci 2013; 58:1880-90. [PMID: 23543084 DOI: 10.1007/s10620-013-2569-1] [Citation(s) in RCA: 10] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/19/2012] [Accepted: 01/06/2013] [Indexed: 12/20/2022]
Abstract
BACKGROUND The X-ray repair cross-complementation group 1 (XRCC1) protein plays an important role in base excision repair. AIM To elucidate the role of XRCC1 Arg399Gln, Arg194Trp and Arg280His genotypes in esophageal cancer risk, all available studies were considered in the present meta-analysis. METHODS Eligible studies were identified by searching several electronic databases for relevant reports published before June 2012. RESULTS According to the inclusion criteria and exclusion criteria, a total of 21 eligible studies were included in the pooled analyses. Among the 21 studies, 18 focused on Arg399Gln polymorphism, 11 described the Arg194Trp, and 4 articles investigated on Arg280His. Our analysis suggested that there was no evidence of significant association between XRCC1 Arg399Gln polymorphism and esophageal cancer risk in any genetic model. In the stratified analysis by ethnicity for Arg399Gln polymorphism and esophageal cancer, the results showed that Arg399Gln polymorphism was not associated with esophageal cancer risk. Only 4 studies analyzed the relationship between XRCC1 Arg280His polymorphism and the risk of esophageal cancer. The Arg/His and His/His genotypes were not significantly associated with increased risk of EC. A similar negative association was maintained in dominant and recessive models. However, for XRCC1 Arg194Trp polymorphism, our study showed individuals carrying the variant genotype Trp/Trp had a significant increased risk of esophageal cancer (OR = 1.295, 95 % CI 1.053-1.591, P = 0.014). In addition, increased associations were found in recessive model (OR = 1.332, 95 % CI 1.093-1.624, P = 0.005). CONCLUSIONS Our meta-analysis suggested that Arg194Trp Trp allele might act as a risk allele in its association with esophageal cancer.

Abstract
OBJECTIVE To investigate the association between xeroderma pigmentosum group D (XPD) Asp312Asn polymorphism and esophageal cancer (EC) susceptibility by meta-analysis. METHODS We searched PubMed up to April 9th, 2012, to identify relevant papers, and 8 published case-control studies including 2165 EC patients and 3141 healthy controls were yielded. Odds ratios (ORs) with relevant 95% confidence intervals (CIs) were applied to assess the association between XPD Asp312Asn polymorphism and EC susceptibility with the Comprehensive Meta-Analysis software, version 2.2. RESULTS Overall, the meta-analysis results suggested the XPD Asp312Asn polymorphism to be significantly associated with EC susceptibility [(Asn/Asn+Asp/Asn) vs. Asp/Asp: OR=1.20, 95%CI=1.05-1.36, p=0.01; and Asp/Asn vs. Asp/Asp: OR=1.15, 95%CI=1.01-1.31, p=0.04]. In the subgroup analysis by ethnicity and cancer type, significantly associations were found for Caucasian populations [(Asn/Asn+Asp/Asn) vs. Asp/Asp: OR=1.26, 95%CI=1.08-1.47, p<0.001; Asp/Asn vs. Asp/Asp: OR=1.19, 95%CI=1.02- 1.40, p=0.03] and esophageal squamous cell carcinoma [(Asn/Asn+Asp/Asn) vs. Asp/Asp: OR=1.19, 95%CI=1.01-1.41, p=0.04]. There was no heterogeneity and no publication bias existed. CONCLUSIONS This meta-analysis shows that the XPD Asp312Asn polymorphism may be a risk factor for developing EC, especially for Caucasian populations and esophageal squamous cell carcinoma.

Abstract
The matrix metalloproteinase (MMP) family of proteins mediates various cellular pathways, including apoptosis and angiogenesis. Polymorphisms of MMP genes are associated with increased esophageal adenocarcinoma (EAC) risk. Gastroesophageal reflux disease (GERD) is an established EAC risk factor. We examined whether MMP polymorphism-EAC risk is modified by GERD. In total, 309 EAC patients and 279 frequency-matched healthy controls underwent MMP1 1G/2G, MMP3 6A/5A, MMP12 -82A/G and MMP12 1082A/G genotyping. Questionnaires collected GERD history. EAC risk was analyzed using logistic regression, adjusted for key covariates and stratified by GERD. Joint effects models explored GERD severity and duration, whereas additional models explored genotype-GERD interactions in EAC risk. We determined that each MMP1 and MMP3 minor (variant) allele was independently associated with increased EAC risk (adjusted odds ratio (AOR) 3.2, 95% confidence interval (CI) 2.0-5.1, p < 0.001 and AOR 1.8, 95% CI 1.1-2.7, p = 0.01, respectively) only among those with GERD but not in GERD-free individuals (all p = nonsignificant). There were significant interactions between the MMP1 variants and the presence of GERD (p = 0.002) and between MMP3 variants and GERD (p = 0.04). There was an equally strong interaction between cumulative GERD severity and MMP1 (p = 0.002). The AOR of each variant allele was 14.9 (95% CI 1.6-136) for individuals with severe GERD, 1.7 (95% CI 1.0-2.7) for mild-moderate GERD and 0.98 (95% CI 0.7-1.4) for those without GERD. This was further reflected in separate analyses of frequency and duration of GERD. In conclusion, MMP1 1G/2G (and possibly MMP3 6A/5A) polymorphisms alter EAC risk differentially for GERD and GERD-free individuals.

XPD Lys751Gln polymorphism and esophageal cancer susceptibility: a meta-analysis of case-control studies. Mol Biol Rep 2011; 39:2533-40.

Abstract
The published data on the association between xeroderma pigmentosum group D (XPD) Lys751Gln polymorphism and esophageal cancer (EC) remained controversial. The present meta-analysis of literatures was performed to derive a more precise estimation of the relationship. A comprehensive literature search was conducted to identify all case-control studies of Lys751Gln polymorphism and risk for two main types of EC: esophageal adenocarcinoma (EADC) and esophageal squamous cell carcinoma (ESCC). A total of 12 studies were identified to the meta-analysis, including 2,575 cases (1,294 ESCC and 1,281 EADC) and 4,951 controls (1,891 ESCC and 3,060 EADC). Random-effects or fix-effects model was used according to between-study heterogeneity. The odds ratio (OR) for the variant homozygous genotype Gln/Gln of the Lys751Gln polymorphism, compared with the wild type homozygote Lys/Lys, was 1.26, with 95% confidence interval (95% CI) 1.02-1.56, for EADC risk without between-study heterogeneity. When stratified by ethnicity, statistically significantly elevated risk was found among Chinese (Gln/Gln vs. Lys/Lys: OR 2.45, 95% CI = 1.10-5.44). However, no significant associations were found between XPD Lys751Gln polymorphism and EC risk when all studies pooled into the meta-analysis (Lys/Gln vs. Lys/Lys: OR 1.07, 95% CI = 0.88-1.28; Gln/Gln vs.us Lys/Lys: OR 1.25, 95% CI = 0.92-1.71; dominant model: OR 1.09, 95% CI = 0.90-1.33). In conclusion, this meta-analysis suggests that the Lys751Gln genetic polymorphism may be a potential biomarker of EC susceptibility in Chinese populations. And a study with the larger sample size is needed to further evaluate gene-environment interaction on XPD Lys751Gln polymorphism and EC risk.

Abstract
AIM: To evaluate the association between xeroderma pigmentosum group D (XPD), genetic polymorphism Lys751Gln and esophageal cancer risk.
METHODS: We searched PubMed up to September 1, 2010 to identify eligible studies. A total of 10 case-control studies including 2288 cases and 4096 controls were included in the meta-analysis. Statistical analysis was performed with Review Manage version 4.2. Odds ratios (ORs) with 95% confidence intervals (CIs) were used to assess the strength of the association.
RESULTS: The results suggested that there is no significant association between XPD Lys751Gln polymorphism and esophageal cancer susceptibility in the overall population. However, in subgroup analysis by histology type, a significant association was found between XPD Lys751Gln polymorphism and esophageal adenocarcinoma (for CC vs AA: OR = 1.25, 95% CI = 1.01-1.55, P = 0.05 for heterogeneity).
CONCLUSION: Our meta-analysis suggested that XPD Lys751Gln polymorphism may be associated with increased risk of esophageal adenocarcinoma.

Abstract
Multiple factors play a role in the pathogenesis of gastroesophageal reflux disease (GERD). Two landmark studies showing higher concordance of disease in monozygotic than dizygotic twin pairs suggested the role of host genetic factors in its pathogenesis. Recent studies have shown that genetic polymorphism in genes influencing host's inflammatory response, drug metabolism, cell cycle regulation, xenobiotic pathways, DNA repair, mutagenesis, esophageal sensory function and gene silencing are associated with risk of GERD and its sequelae-Barrett's esophagus and esophageal adenocarcinoma. However, more studies on larger sample size are needed before reaching a definite conclusion on the role of an individual gene.

Abstract
PURPOSE Germline genetic variations may partly explain the clinical observation that normal tissue tolerance to radiochemotherapy varies by individual. Our objective was to evaluate the association between single-nucleotide polymorphisms (SNPs) in radiation/platinum pathways and serious treatment-related toxicity in subjects with esophageal adenocarcinoma who received cisplatin-based preoperative radiochemotherapy. METHODS In a multicenter clinical trial (E1201), 81 eligible treatment-naïve subjects with resectable esophageal adenocarcinoma received cisplatin-based chemotherapy concurrent with radiotherapy, with planned subsequent surgical resection. Toxicity endpoints were defined as grade ≥3 radiation-related or myelosuppressive events probably or definitely related to therapy, occurring during or up to 6 weeks following the completion of radiochemotherapy. SNPs were analyzed in 60 subjects in pathways related to nucleotide/base excision- or double stranded break repair, or platinum influx, efflux, or detoxification. RESULTS Grade ≥3 radiation-related toxicity (mostly dysphagia) and myelosuppression occurred in 18 and 33% of subjects, respectively. The variant alleles of the XRCC2 5' flanking SNP (detected in 28% of subjects) and of GST-Pi Ile-105-Val (detected in 65% of subjects) were each associated with higher odds of serious radiation-related toxicity compared to the major allele homozygote (47% vs. 9%, and 31% vs. 0%, respectively; P = 0.005). No SNP was associated with myelosuppression. CONCLUSIONS This novel finding in a well-characterized cohort with robust endpoint data supports further investigation of XRCC2 and GST-Pi as potential predictors of radiation toxicity.

Abstract
Polymorphisms in DNA repair genes were thought to represent important determinants of platinum drug efficacy. This study tested whether XPD Lys751Gln and XRCC1 T-77C polymorphisms were associated with survival in platinum-treated patients with advanced non-small-cell lung cancer (NSCLC). In this study, 199 advanced NSCLC patients with platinum-based chemotherapy were recruited. During the median 26.5 months of follow-up, patients with the XPD 751Lys/Lys genotype had a median survival time of 17.0 months (95% CI, 14.5-19.6 months), not much longer than those carried Lys/Gln heterozygote (12.0 months; 95% CI, 3.4-20.6 months; log-rank test, P=0.542). In Cox proportional hazards model, no significant associations were found between XPD Lys751Gln polymorphism and survival. For XRCC1 T-77C polymorphism, the median survival of patients with TC+CC genotype (18 months; 95% CI, 13.5-22.5 months) was similar to those with the TT genotype (16.0 months; 95% CI, 13.3-18.7 months; log-rank test, P=0.399). XRCC1 T-77C polymorphism was not associated with survival in Cox proportional hazards model. Additionally, the analysis for combination of these two polymorphisms also showed no prognostic significance for NSCLC. Our findings indicated that neither XPD Lys751Gln nor XRCC1 T-77C could be genetic determinant for prognosis of advanced NSCLC patients treated with platinum-based chemotherapy.

Abstract
Relationship between Helicobacter pylori (H. pylori) and gastroesophageal reflux disease (GERD) is controversial. We aimed to review the possible relationship between H. pylori infection and GERD. Epidemiological data indicate an inverse relationship between frequency of H. pylori infection and prevalence of GERD and its complications like Barrett's esophagus and esophageal adenocarcinoma. H. pylori eradication in patients with peptic ulcer disease may be associated with increased risk of development of GERD compared with untreated patients. Infection with cagA bearing strains of H. pylori was associated with less severe GERD including endoscopic esophagitis, possibly due to pangastritis leading to hypochlorhydria. Recent studies on inflammatory markers (IL-1β and IL-1RN) suggest pro-inflammatory genotypes to be protective against development of severe GERD, especially in patients with H. pylori infection. Identification of candidate genes playing an important role in gastric acid secretion and visceral hypersensitivity to the esophageal epithelium might help in early detection of individuals susceptible to develop GERD. Interplay between H. pylori and host factors play an important role in the pathogenesis of GERD.

Abstract
In the present study we investigated the association between three polymorphisms of the MUTYH (Tyr165Cys, rs34612342), the OGG1 (Ser326Cys, rs1052133) and the XPD (Lys751Gln, rs13181) genes with head and neck cancer risk. Genotypes were determined in DNA from peripheral blood lymphocytes of 265 patients with head and neck squamous cell carcinoma (HNSCC) as well as 280 cancer-free controls by PCR-restriction fragment length polymorphisms. We found an association between HNSCC and the Ser326Cys (OR 1.69; 95% CI 1.19-2.45) as well as Cys326Cys (OR 4.56; 95% CI 2.07-10.05) variants of the OGG1 gene. The gene-gene interaction between MUTYH and OGG1 as well as OGG1 and XPD polymorphic variants may contribute to higher prevalence of HNSCC. We also found an association between Ser326Cys and Cys326Cys variants of OGG1 gene and smoking status in HNSCC patients (OR 1.97; 95% CI 1.25-3.11), (OR 3.54; 95% CI 1.39-9.04), respectively. Moreover, we also observed a protective association between Tyr165Cys variant of the MUTYH gene and non-smoking status in HNSCC (OR 0.34; 95% CI 0.17-0.66). We also found a link between gene-gene interaction (MUTYH and OGG1 or OGG1 and XPD) and smoking (ORs 2.17-4.20 and 2.18-5.23) or non-smoking status (ORs 0.11 and 7.61) in HNSCC patients, respectively. In conclusion our data showed that the Ser326Cys polymorphism of the OGG1 gene may modify the risk of HNSCC associated with smoking. Finally we suggested that this polymorphism might be used as predictive factor for head and neck cancer in Polish population.

Abstract
The base excision repair (BER) pathway is important in repairing DNA damage incurred from occupational exposure to 1,3-butadiene (BD). This study examines the relationship between inherited polymorphisms of the BER pathway (x-ray repair cross-complementing group 1 (XRCC1) Arg194Trp, Arg280His, Arg399Gln, T-77C, ADPRT Val762Ala, MGMT Leu84Phe and APE1 Asp148Glu) and chromosomal damage in BD-exposed workers, using the cytokinesis-blocked (CB) micronucleus (MN) assay in peripheral lymphocytes of 166 workers occupationally exposed to BD and 41 non-exposed healthy individuals. The MN frequency of exposed workers (3.39 +/- 2.42) per thousand was higher than that of the non-exposed groups (1.48 +/- 1.26) per thousand (P < 0.01). Workers receiving greater than median annual BD exposures had higher MN values than lower exposed workers: frequency ratio (FR) of 1.30, 95% confidence interval (CI) 1.14-1.53; P < 0.05. Workers who carried the following genotypes were associated with greater frequency of MN (P < 0.05 for each comparison, unless specified): XRCC1 -77 C/T genotype (FR = 1.28, 95% CI: 1.04-1.57; reference C/C), ADPRT 762 Ala/Ala (FR = 1.54, 95% CI: 1.17-2.03; P < 0.01), XRCC1 194 Arg/Trp (FR = 1.13, 95% CI: 0.87-1.27; reference, Arg/Arg), XRCC1 280 Arg/His (FR = 1.67, 95% CI: 1.10-2.42; reference, Arg/Arg), XRCC1 399 Arg/Gln and Gln/Gln genotypes (FR = 1.26, 95% CI: 1.03-1.53 and FR = 1.24, 95% CI 1.03-1.49; reference Arg/Arg, respectively). As XRCC1 polymorphisms were linked, workers carrying the XRCC1 (-77)-(194)-(280)-(399) diplotype, TCGA/TCGA, had a higher MN frequency compared with individuals carrying the wild-type CCGG/CCGG (FR = 1.57, 95% CI: 1.02-2.41; P < 0.05). In conclusion, CB-MN is a sensitive index of early damage among BD-exposed workers. In workers exposed to BD, multiple BER polymorphisms and a XRCC1 haplotype were associated with differential levels of chromosome damage.

Abstract
HIV/AIDS remains to be one of the killing diseases of mankind. Host genetic response is one of the factor which determine susceptibility to HIV and disease progression to AIDS. The aim of the present study was to evaluate the impact of ERCC2 Lyc ( 751 ) Gln (excision repair cross complementing rodent repair deficiency, complementation group 2) polymorphism on HIV-1 susceptibility and disease progression to AIDS, as this gene has been reported to intervene in degrading retroviral cDNA before it integrates with the host DNA. This case control study included 300 HIV seropositive cases and an equal number of HIV seronegative controls. DNA was isolated from the blood samples of study subjects and genotyping of ERCC2 was conducted by polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP) method. The Gln/Gln genotype showed a significant variation between cases and controls (P = 0.047, OR 1.71, 95% CI 1.00-2.93), indicating a possible role of susceptibility in reference to controls and disease progression when compared within cases.

Abstract
p53 Arg72Pro, MDM2 T309G, and CCND1 G870A are functional single-nucleotide polymorphisms (SNPs) in key genes that regulate apoptosis and cell cycle. Variant genotypes of these SNPs have been associated with increased risk and earlier age of onset in some cancers. We investigated the association of these SNPs with susceptibility to esophageal adenocarcinoma in a large, North American case-control study. Three hundred and twelve cases and 454 cancer-free controls recruited in Boston, USA were genotyped for each of the three SNPs, and demographic and clinical data were collected. Genotype frequencies for each of the three SNPs did not deviate from the Hardy-Weinberg equilibrium, and did not differ between cases and controls. Odds ratios (OR), adjusted for clinical risk factors, for the homozygous variant genotypes were 0.99 (95% confidence interval [CI] 0.57-1.72) for p53 Pro/Pro, 0.81 (95% CI 0.52-1.28) for MDM2 G/G, and 0.97 (95% CI 0.64-1.49) for CCND1 A/A. The analysis was adequately powered (80%) to detect ORs of 1.37, 1.35, and 1.34 for each SNP, respectively. In contrast to the results of smaller published studies, no association between p53 Arg72Pro, MDM2 T309G, and CCND1 G870A SNPs and susceptibility to esophageal adenocarcinoma, age of onset, or stage of disease at diagnosis was detected.

Abstract
OBJECTIVES Genetic variations or polymorphisms within genes of the nucleotide excision repair (NER) pathway alter DNA repair capacity. Reduced DNA repair (NER) capacity may result in tumors that are more susceptible to cisplatin chemotherapy, which functions by causing DNA damage. We investigated the potential predictive significance of functional NER single nucleotide polymorphisms in esophageal cancer patients treated with (n = 262) or without (n = 108) cisplatin. METHODS Four NER polymorphisms XPD Asp312Asn; XPD Lys751Gln, ERCC1 8092C/A, and ERCC1 codon 118C/T were each assessed in polymorphism-cisplatin treatment interactions for overall survival (OS), with progression-free survival (PFS) as a secondary endpoint. RESULTS No associations with ERCC1 118 were found. Polymorphism-cisplatin interactions were highly significant in both OS (P = 0.002, P = 0.0001, and P < 0.0001) and PFS (P = 0.006, P = 0.008, and P = 0.0007) for XPD 312, XPD 751, and ERCC1 8092, respectively. In cisplatin-treated patients, variant alleles of XPD 312, XPD 751, and ERCC1 8092 were each associated with significantly improved OS (and PFS): adjusted hazard ratios of homozygous variants versus wild-type ranged from 0.22 [95% confidence interval (CI): 0.1-0.5] to 0.31 (95% CI: 0.1-0.7). In contrast, in patients who did not receive cisplatin, variant alleles of XPD 751 and ERCC1 8092 had significantly worse survival, with adjusted hazard ratios of homozygous variants ranging from 2.47 (95% CI: 1.1-5.5) to 3.73 (95% CI: 1.6-8.7). Haplotype analyses affirmed these results. CONCLUSION DNA repair polymorphisms are associated with OS and PFS, and if validated may predict for benefit from cisplatin therapy in patients with esophageal cancer.

Abstract
Aging is associated with progressing genomic instability. The XPD gene encodes a DNA helicase involved in nucleotide excision repair and in transcription. We analyzed the common XPD polymorphisms that were previously shown to affect protein's DNA repair efficiency and to increase the risk of developing various cancers. Analysis was performed in 149 centenarians (mean age 101.1 years old) and in 413 young subjects (mean age 27.1 years old). We showed that the distribution of the Lys751Gln genotypes differed significantly between these groups (P = 0.017). In centenarians, the homozygous genotypes AA and CC were found less frequently than in young controls (29 vs. 36%, OR = 0.71, and 14 vs. 20%, OR = 0.652, respectively). The Arg156Arg and Asp312Asn were not significantly associated with extreme longevity. Analysis of the XPD mRNA level in blood mononuclear cells of people divided into three age groups (mean ages 28.7, 65.8 and 92.7 years old) showed that extreme longevity is associated with the decrease of the mean level of the specific mRNA; the differences between young or middle-aged vs. extremely old group were significant (P < 0.0001, P < 0.0001, respectively). In addition, the methylation pattern of the XPD promoter was analyzed in 30 people divided into three age groups (29.5, 65.9, and 101.4 years old). We showed that overall methylation of the XPD promoter is a rare event; however, aging is associated with the increase of methylation level upstream of the transcription start site. In summary, we showed for the first time that both the XPD polymorphic variants and the decreased level of its expression might be associated with aging.

Abstract
The matrix metalloproteinase (MMP) family degrade extracellular matrix and mediate pathways including apoptosis, angiogenesis and immunity. We studied the association between four MMP polymorphisms within three MMP genes and esophageal adenocarcinoma (EA) risk and prognosis. A total of 313 EA cases and 455 age and gender frequency-matched controls were genotyped for MMP1 1G/2G, MMP3 6A/5A, MMP12 -82A/G and MMP12 1082A/G. The association between individual MMP polymorphisms and EA risk was evaluated using regression models and adjusted for age, gender, adult body mass index and smoking status. Haplotype analysis was performed to investigate the combined effect of all four linked MMP polymorphisms and EA risk. The MMP1 and MMP3 polymorphisms were associated with increased EA risk: MMP1 1G/2G and 2G/2G had adjusted odds ratios of 1.46 [95% confidence interval 1.0-2.1; P = 0.04] and adjusted odds ratio 1.83 (1.2-2.8; P = 0.005), respectively, whereas MMP3 6A/5A had adjusted odds ratio 1.40 (95% confidence interval 1.0-2.1; P = 0.09) and MMP3 5A/5A had 1.61 (95% confidence interval 1.0-2.5; P = 0.03). Two MMP haplotypes [MMP1-MMP3-MMP12 (-82) 2G-5A-A (adjusted odds ratio 1.36, 95% confidence interval 1.0-1.8; P = 0.03) and 2G-5A-G (adjusted odds ratio 1.70, 95% confidence interval 1.1-2.6; P = 0.01)] were also associated with increased EA risk. The relationship between BE cases with the same set of controls was similar. No association was identified between the MMP polymorphisms and overall survival or progression free survival of patients with EA. MMP1, MMP3 and possibly MMP12 -82A/G polymorphisms and their haplotypes are associated with increased EA risk.

Abstract
In this case-control study with 387 White esophageal patients and 462 White controls matched to cases by age and sex, we evaluated the associations between 13 potential functional polymorphisms in eight major nucleotide excision repair (NER) genes and esophageal cancer risk. In individual single nucleotide polymorphism analysis, after adjustment for multiple comparisons, the heterozygous GT genotype of the ERCC1 3' untranslated region (UTR) was associated with an increased risk, whereas the homozygous variant genotype TT was associated with 60% reduction in risk with an odds ratio (OR) of 0.40 (95% confidence interval [CI] = 0.19-0.86). The heterozygous AG genotype of XPA 5' UTR was at 2.11-fold increased risk (95% CI = 1.33-3.35) and the risk reached 3.10-fold (95% CI = 1.94-4.95) for the homozygous variant GG genotype. These associations were also significant when restricted the analyses in patients with esophageal adenocarcinoma. Further, the CT genotype of the RAD23B Ala249Val was associated with increased esophageal cancer risk (OR = 1.44; 95% CI = 1.05-1.97), whereas the poly-AT-/+ genotype of the XPC intron 9 conferred a decreased risk (OR = 0.71, 95% CI = 0.51-0.97). In joint analysis, individuals carrying 1 (OR = 2.64, 95% CI = 1.57-4.52) and > or = 2 (OR = 2.74, 95% CI = 1.58-4.75) unfavorable genotypes exhibited significantly increased risk for esophageal cancer risk with significant dose-response trend (P for trend = 0.006). The pathway-based risk was more evident in ever smokers, overweight/obese individuals, men and ever drinkers. Our results support the hypothesis that increasing numbers of unfavorable genotypes in the NER predispose susceptible individuals to increased risk of esophageal cancer. These findings warrant further replications in different populations.

Abstract
Investigations into inherited genetic variations in the DNA code (known as polymorphisms) in the field of oncology have provided preliminary support for an association with cancer risks and outcomes. Early studies have highlighted several genes with this potential predictive and prognostic power. However, these studies have had methodological limitations and have produced inconsistent results, making impractical as yet the routine evaluation of such genetic polymorphisms in general clinical practice. Continued research in this area is essential if we are to be able to soon use genetic polymorphisms to better select patients for targeted anticancer interventions. This review discusses the role of genetic polymorphisms and their association with esophageal cancer risk and prognosis. The article also highlights future directions in this new, emerging field of molecular epidemiology.

Abstract
PURPOSE Functional variation in DNA repair capacity through single nucleotide polymorphisms (SNPs) of key repair genes is associated with a higher risk of developing various types of cancer. Studies have focused on the nucleotide excision repair (NER) and base excision repair (BER) pathways. We investigated whether variant alleles in seven SNPs within these pathways increased the risk of esophageal adenocarcinoma. METHODS DNA was extracted from prospectively collected blood specimens. The samples were genotyped for SNPs in NER genes (XPD Lys751Gln, XPD Asp312Asn, ERCC1 8092C/A, and ERCC1 118C/T), and BER genes (XRCC1 Arg399Gln, APE1 Asp148Glu, and hOGG1 Ser326Cys). The presence of variant alleles was correlated with risk of esophageal adenocarcinoma both individually and jointly. RESULTS Variant alleles in NER SNPs XPD Lys751Gln (AOR = 1.50, 95% CI 1.1-2.0), ERCC1 8092 C/A (AOR = 1.44, 95% CI 1.1-1.9), and ERCC1 118C/T (AOR = 1.42, 95% CI 1.0-1.9) were individually associated with esophageal adenocarcinoma risk. An increasing number of variant alleles in NER SNPs showed a significant trend with esophageal adenocarcinoma risk (p = 0.007). CONCLUSIONS The presence of variant alleles in NER genes increases risk of esophageal adenocarcinoma. There is evidence of an additive role for SNPs along a common DNA repair pathway. Future larger studies of esophageal adenocarcinoma etiology should evaluate entire biological pathways.

Abstract
Head and neck cancer (HNC) patients have variable prognoses even within the same clinical stage and while receiving similar treatments. The number of studies of genetic polymorphisms as prognostic factors of HNC outcomes is growing. Candidate polymorphisms have been evaluated in DNA repair, cell cycle, xenobiotic metabolism, and growth factor pathways. Polymorphisms of XRCC1, FGFR, and CCND1 have been consistently associated with HNC survival in at least two studies, whereas most of the other polymorphisms have either conflicting data or were from single studies. Heterogeneity and lack of description of patient populations and lack of accounting for multiple comparisons were common problems in a significant proportion of studies. Despite a large number of exploratory studies, large replication studies in well-characterized HNC populations are warranted.

Abstract
Genetic variations in the XPD gene may increase cancer susceptibility by affecting the capacity for DNA repair. Several studies have investigated this possibility; however, the conclusions remain controversial. Therefore, we did a systematic review and executed a meta-analysis to explore the association. From 56 studies, a total of 61 comparisons included 25,932 cases and 27,733 controls concerning the Lys 751Gln polymorphism; 35 comparisons included 16,781 cases and 18,879 controls in the case of Asp 312 Asn were reviewed. In this analysis, small associations of the XPD Lys 751 Gln polymorphism with cancer risk for esophageal cancer [for Lys/Gln versus Lys/Lys: odds ratio (OR), 1.34; 95% confidence interval (95% CI), 1.10-1.64; for Gln/Gln versus Lys/Lys: OR, 1.61; 95% CI, 1.16-2.25] and acute lymphoblastic leukemia (for Gln/Gln versus Lys/Lys: OR, 1.83; 95% CI, 1.21-2.75) are revealed. Overall, individuals with the Gln/Gln genotype have a small cancer risk compared with Lys/Lys genotype for the reviewed cancer in total (OR, 1.10; 95% CI, 1.03-1.16). Subtle but significant cancer risk was observed for the XPD Asp 312 Asn polymorphism in bladder cancer (for Asp/Asn versus Asp/Asp: OR, 1.24; 95% CI, 1.06-1.46). No significant associations were found for other cancers separately and all the reviewed cancer in total assessed for the Asp 312 Asn polymorphism. Our study suggests that XPD is a candidate gene for cancer susceptibility regardless of environmental factors.

Abstract
Reflux of gastric contents can lead to development of reflux esophagitis and Barrett's esophagus. Barrett's esophagus is a risk factor for esophageal adenocarcinoma. Damage to DNA may lead to carcinogenesis but is repaired through activation of pathways involving polymorphic enzymes, including human 8-oxoguanine glycosylase 1 (hOGG1), X-ray repair cross-complementing 1 (XRCC1), and xeroderma pigmentosum group D (XPD). Of the single nucleotide polymorphisms identified in these genes, hOGG1 Ser 326 Cys, XRCC1 Arg 399 Gln, and XPD Lys 751 Gln are particularly common in Caucasians and have been associated with lower DNA repair capacity. Small studies have reported associations with XPD Lys 751 Gln and esophageal adenocarcinoma. XRCC1 Arg 399 Gln has been linked to Barrett's esophagus and reflux esophagitis. In a population-based case-control study, we examined associations of the hOGG1 Ser 326 Cys, XRCC1 Arg 399 Gln, and XPD Lys 751 Gln polymorphisms with risk of esophageal adenocarcinoma, Barrett's esophagus, and reflux esophagitis. Genomic DNA was extracted from blood samples collected from cases of esophageal adenocarcinoma (n = 210), Barrett's esophagus (n = 212), reflux esophagitis (n = 230), and normal population controls frequency matched for age and sex (n = 248). Polymorphisms were genotyped using TaqMan allelic discrimination assays. Odds ratios and 95% confidence intervals were obtained from logistic regression models adjusted for potential confounding factors. There were no statistically significant associations between these polymorphisms and risk of esophageal adenocarcinoma, Barrett's esophagus, or reflux esophagitis.

Abstract
Rates of adenocarcinoma of the esophagus (EAC) and esophago-gastric junction (EGJAC) have increased rapidly in recent decades. The primary risk factors, gastro-esophageal acid reflux and smoking, are potentially genotoxic through the generation of N-nitroso compounds. The DNA repair protein O(6)-methylguanine-DNA methyltransferase (MGMT) is the major cellular defense against alkylating DNA damage. We compared patients with EAC (n = 263) or EGJAC (n = 303) with matched population controls (n = 1,337) for the frequency of 5 MGMT single nucleotide polymorphisms (SNPs) (rs12269324, rs12268840, L84F, I143V, K178R), as well as SNPs in DNA repair genes ERCC1 (N118N), XRCC1 (Q399R) and XPD (K751Q). Relative risks were estimated using multivariable logistic regression. Potential biological interaction was assessed through the synergy index S. Each MGMT SNP conferred increased risks of EAC but not EGJAC; strongest associations were found for the 2 variant MGMT alleles rs12268840 and I143V (p = 0.005 and p < 0.001, respectively). Homozygous carriers of MGMT rs12268840 with frequent acid reflux had significantly higher risks of EAC (OR 15.5, 95% CI 5.8-42) than expected under an additive model, consistent with biological interaction (S = 3.3, 95% CI 1.1-10). Modest, nonsignificant interactions with smoking were also observed. Homozygous variant ERCC1 genotype was associated with reduced risks of EAC (OR 0.6, 95% CI 0.4-1.1), while the homozygous variant XRCC1 genotype conferred higher risks of EGJAC (OR 1.6, 95% CI 1.1-2.4). No associations with EAC or EGJAC were observed with XPD (rs13181). In summary, MGMT SNPs are associated with increased risks of EAC. Exposure to acid reflux, and possibly smoking, confer markedly higher risks among homozygous variant genotype carriers.

Abstract
PURPOSE The epidermal growth factor (EGF) pathway is important in esophageal adenocarcinoma (EAC) tumorigenesis. We hypothesized that the EGF A61G homozygous variant genotype (GG) is (a) both a risk and poor prognostic factor for EAC and (b) associated with higher EGF serum levels in individuals with gastroesophageal reflux disease (GERD). EXPERIMENTAL DESIGN Using unconditional logistic regression, we compared EGF A61G in 312 EAC cases and 447 GERD-free controls, adjusting for age, gender, smoking history, and healthy adult body mass index. Using the method of Kaplan and Meier, log-rank tests, and Cox proportional hazard models, we correlated EGF A61G with overall and failure-free survival in the EAC cases. Serum EGF levels and EGF genotype (G/G versus others) were correlated in 144 GERD patients using Wilcoxon rank sum tests. RESULTS The EGF A61G G/G genotype conferred increased EAC risk, with an adjusted odds ratio of 1.81 (95% confidence interval, 1.2-2.7), and was even higher in the subgroup of EAC patients with concurrent Barrett's esophagus (adjusted odds ratio, 2.18; 95% confidence interval, 1.3-3.7). However, EGF A61G was not associated with a more aggressive phenotype or prognosis in EAC patients. Higher serum EGF levels were found in GERD patients carrying G/G compared with A/A or A/G (P = 0.03, Wilcoxon rank sum test). CONCLUSION The EGF A61G G/G genotype is associated with a near 2-fold greater risk of EAC. The G/G allele was also associated with higher EGF levels in tumor-free patients with GERD. EGF genotyping can potentially identify high-risk patients with GERD and Barrett's metaplasia who might benefit from increased surveillance.

Abstract
Helicobacter pylori (HP) infection appears protective against oesophageal adenocarcinoma (EA) risk. Matrix metalloproteinases (MMPs) are released in the presence of HP infection. In MMP2 wild-type individuals, HP was significantly protective of EA risk (adjusted odds ratio: 0.29; 95% confidence interval=0.1-0.7). Matrix metalloproteinases may modulate the EA-HP relationship.

Abstract
We studied polymorphisms of three genes, UDP-glucuronosyltransferase1A7 (UGT1A7), Glutathione-S-transferaseM1 (GSTM1) and X-Ray Cross Complementing group 1 (XRCC1), involved in detoxification of xenobiotics or DNA-repair in a population of 133 liver-transplanted patients, including 56 patients with hepatocellular carcinoma (HCC) and 77 without HCC, and in 89 healthy controls originating from the south of France. Multiple logistic regression analysis showed that, among liver-transplanted patients, interactions between XRCC1-G/G or -G/A and GSTM1-nul polymorphisms were independently associated with hepatocellular carcinoma (p interaction=0.027) concurrently with increasing age (p<0.001), male sex (p=0.037) and chronic hepatitis B or C virus infection (p=0.018 and p=0.001 respectively). On the contrary, no relationship was observed between UGT1A7 polymorphisms considered alone or in interaction with GSTM1 or XRCC1 polymorphisms and HCC. This suggests that concomitant impaired metabolism of carcinogenic compounds and impaired DNA-repair function play an important role in liver carcinogenesis in high-risk cirrhotic patients originating from the south of France.

Abstract
The association between oxidative or ultraviolet (UV) light induced DNA damage in the lens epithelium and the development of lens opacities, and the existence of DNA repair in lens epithelial cells have been reported. Polymorphisms of DNA repair enzymes may affect repair efficiency. In this study, we aimed to determine the frequency of polymorphisms in two DNA repair enzyme genes, xeroderma pigmentosum complementation group D (XPD) codon 751 and X-ray cross-complementing group 1 (XRCC1) codon 399, in a sample of Turkish patients with maturity onset cataract. By using polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP), we analysed XRCC1-Arg399Gln and XPD-Lys751Gln polymorphisms in 195 patients with cataract (75 patients with cortical, 53 with nuclear, 37 with posterior subcapsular, and 30 with mixed type) and in 194 otherwise healthy control group of similar age. There was a significant difference between frequencies for XPD-751 Gln/Gln genotype in cataract patients (12%) and healthy controls (20%) (P=0.008, OR=0.40, 95% CI=0.20-0.81). After stratification by the cataract subtypes, XPD-751 Gln/Gln genotype was found to be significantly different in patients with cortical (4%) type cataract in respect to control subjects (20%) (P=0.038, OR=0.16, 95% CI=0.04-0.64). In addition, the allele frequency of the C (Gln)-allele of XPD-Lys751Gln was found to be significantly different in mixed type cataract group (P=0.008, OR=0.48, 95% CI: 0.26-0.90). No statistically significant difference was found for the genotypic and allelic distributions of the polymorphisms in XRCC1 gene between the groups. These findings suggest that polymorphism in XPD codon 751 may be associated with the development of maturity onset cataract.
