Abstract
Lipid peroxidation is considered a unifying mechanistic pathway through which known risk factors induce renal cell carcinoma (RCC). We hypothesized that genes selected a priori for their role in lipid peroxidation would modify cancer risk. We genotyped 635 single nucleotide polymorphisms (SNP) in 38candidate genes in 777 Caucasian RCC cases and 1,035 controls enrolled in a large European case-control study. Top candidate SNPs were confirmed among 718 Caucasian cases and 615 controls in a second study in the United States. Two of the three SNPs (rs8106822 and rs405509) that replicated in the U.S. study were within a regulatory region of the APOE promoter. The OR for rs8106822 A>G variant was 1.22(AG) and 1.41(GG) (P(trend) = 0.01) in the European study, 1.05(AG) and 1.51(GG) (P(trend) = 0.03) in the U.S. study, and 1.15(AG) and 1.44(GG) (P(trend) = 0.001) among 1,485 cases and 1,639 controls combined. The rs405509 G>T variant was associated with risk in the European (OR, 0.87(TG); OR, 0.71(TT); P(trend) = 0.02), the U.S. (OR, 0.68(TG); OR, 0.71(TT); P(trend) = 0.02), and both studies combined (OR(TG), 0.79; OR(TT), 0.71; P(trend) = 0.001), as was the G-G haplotype (r(2) = 0.64; P= 4.7 x 10(-4)). This association is biologically plausible as SNP rs405509 was shown to modify protein binding and transcriptional activity of the APOE protein in vitro and is in linkage disequilibrium with key known variants defining the e2, e3, and e4 alleles that modify risk of atherosclerosis, Alzheimer's disease risk, and progression to AIDS. In two large case-control studies, our findings further define a functional region of interest at the APOE locus that increases RCC susceptibility.

Abstract
BACKGROUND Genetic variants in 15q25 have been identified as potential risk markers for lung cancer (LC), but controversy exists as to whether this is a direct association, or whether the 15q variant is simply a proxy for increased exposure to tobacco carcinogens. METHODS We performed a detailed analysis of one 15q single nucleotide polymorphism (SNP) (rs16969968) with smoking behaviour and cancer risk in a total of 17 300 subjects from five LC studies and four upper aerodigestive tract (UADT) cancer studies. RESULTS Subjects with one minor allele smoked on average 0.3 cigarettes per day (CPD) more, whereas subjects with the homozygous minor AA genotype smoked on average 1.2 CPD more than subjects with a GG genotype (P < 0.001). The variant was associated with heavy smoking (>20 CPD) [odds ratio (OR) = 1.13, 95% confidence interval (CI) 0.96-1.34, P = 0.13 for heterozygotes and 1.81, 95% CI 1.39-2.35 for homozygotes, P < 0.0001]. The strong association between the variant and LC risk (OR = 1.30, 95% CI 1.23-1.38, P = 1 x 10(-18)), was virtually unchanged after adjusting for this smoking association (smoking adjusted OR = 1.27, 95% CI 1.19-1.35, P = 5 x 10(-13)). Furthermore, we found an association between the variant allele and an earlier age of LC onset (P = 0.02). The association was also noted in UADT cancers (OR = 1.08, 95% CI 1.01-1.15, P = 0.02). Genome wide association (GWA) analysis of over 300 000 SNPs on 11 219 subjects did not identify any additional variants related to smoking behaviour. CONCLUSIONS This study confirms the strong association between 15q gene variants and LC and shows an independent association with smoking quantity, as well as an association with UADT cancers.

Abstract
In the kidney vitamin D is converted to its active form. Since vitamin D exerts its activity through binding to the nuclear vitamin D receptor (VDR), most genetic studies have primarily focused on variation within this gene. Therefore, analysis of genetic variation in VDR and other vitamin D pathway genes may provide insight into the role of vitamin D in renal cell carcinoma (RCC) etiology. RCC cases (N = 777) and controls (N = 1,035) were genotyped to investigate the relationship between RCC risk and variation in eight target genes. Minimum-p-value permutation (Min-P) tests were used to identify genes associated with risk. A three single nucleotide polymorphism (SNP) sliding window was used to identify chromosomal regions with a False Discovery Rate of <10%, where subsequently, haplotype relative risks were computed in Haplostats. Min-P values showed that VDR (p-value = 0.02) and retinoid-X-receptor-alpha (RXRA) (p-value = 0.10) were associated with RCC risk. Within VDR, three haplotypes across two chromosomal regions of interest were identified. The first region, located within intron 2, contained two haplotypes that increased RCC risk by approximately 25%. The second region included a haplotype (rs2239179, rs12717991) across intron 4 that increased risk among participants with the TC (OR = 1.31, 95% CI = 1.09–1.57) haplotype compared to participants with the common haplotype, TT. Across RXRA, one haplotype located 3′ of the coding sequence (rs748964, rs3118523), increased RCC risk 35% among individuals with the variant haplotype compared to those with the most common haplotype. This study comprehensively evaluated genetic variation across eight vitamin D pathway genes in relation to RCC risk. We found increased risk associated with VDR and RXRA. Replication studies are warranted to confirm these findings.

Abstract
BACKGROUND Alcohol is an important determinant of the high and fluctuating adult mortality rates in Russia, but cause-specific detail is lacking. Our case-control study investigated the effects of alcohol consumption on male and female cause-specific mortality. METHODS In three Russian industrial cities with typical 1990s mortality patterns (Tomsk, Barnaul, Biysk), the addresses of 60,416 residents who had died at ages 15-74 years in 1990-2001 were visited in 2001-05. Family members were present for 50,066 decedents; for 48,557 (97%), the family gave proxy information on the decedents' past alcohol use and on potentially confounding factors. Cases (n=43,082) were those certified as dying from causes we judged beforehand might be substantially affected by alcohol or tobacco; controls were the other 5475 decedents. Case versus control relative risks (RRs; calculated as odds ratios by confounder-adjusted logistic regression) were calculated in ever-drinkers, defining the reference category by two criteria: usual weekly consumption always less than 0.5 half-litre bottles of vodka (or equivalent in total alcohol content) and maximum consumption of spirits in 1 day always less than 0.5 half-litre bottles. Other ever-drinkers were classified by usual weekly consumption into three categories: less than one, one to less than three, and three or more (mean 5.4 [SD 1.4]) bottles of vodka or equivalent. FINDINGS In men, the three causes accounting for the most alcohol-associated deaths were accidents and violence (RR 5.94, 95% CI 5.35-6.59, in the highest consumption category), alcohol poisoning (21.68, 17.94-26.20), and acute ischaemic heart disease other than myocardial infarction (3.04, 2.73-3.39), which includes some misclassified alcohol poisoning. There were significant excesses of upper aerodigestive tract cancer (3.48, 2.84-4.27) and liver cancer (2.11, 1.64-2.70). Another five disease groups had RRs of more than 3.00 in the highest alcohol category: tuberculosis (4.14, 3.44-4.98), pneumonia (3.29, 2.83-3.83), liver disease (6.21, 5.16-7.47), pancreatic disease (6.69, 4.98-9.00), and ill-specified conditions (7.74, 6.48-9.25). Although drinking was less common in women, the RRs associated with it were generally more extreme. After correction for reporting errors, alcohol-associated excesses accounted for 52% of all study deaths at ages 15-54 years (men 8182 [59%] of 13968, women 1565 [33%] of 4751) and 18% of those at 55-74 years (men 3944 [22%] of 17,536, women 1493 [12%] of 12 302). Allowance for under-representation of extreme drinkers would further increase alcohol-associated proportions. Large fluctuations in mortality from these ten strongly alcohol-associated causes were the main determinants of recent fluctuations in overall mortality in the study region and in Russia as a whole. INTERPRETATION Alcohol-attributable mortality varies by year; in several recent years, alcohol was a cause of more than half of all Russian deaths at ages 15-54 years. Alcohol accounts for most of the large fluctuations in Russian mortality, and alcohol and tobacco account for the large difference in adult mortality between Russia and western Europe.

Abstract
BACKGROUND Obesity is a risk factor for several cancers although appears to have an inverse association with cancers strongly related to tobacco. Studying obesity is difficult due to numerous biases and confounding. METHODS To avoid these biases we used a Mendelian randomization approach incorporating an analysis of variants in the FTO gene that are strongly associated with BMI levels among 7000 subjects from a study of lung, kidney and upper-aerodigestive cancer. RESULTS The FTO A allele which is linked with increased BMI was associated with a decreased risk of lung cancer (allelic odds ratio (OR) = 0.92, 95% confidence interval (CI) 0.84-1.00). It was also associated with a weak increased risk of kidney cancer, which was more apparent before the age of 50 (OR = 1.44, CI 1.09-1.90). CONCLUSION Our results highlight the potential for genetic variation to act as an unconfounded marker of environmentally modifiable factors, and offer the potential to obtain estimates of the causal effect of obesity. However, far larger sample sizes than studied here will be required to undertake this with precision.

Abstract
We conducted a case-control study of renal cancer (987 cases and 1298 controls) in Central and Eastern Europe and analyzed genomic DNA for 319 tagging single-nucleotide polymorphisms (SNPs) in 21 genes involved in cellular growth, differentiation and apoptosis using an Illumina Oligo Pool All (OPA). A haplotype-based method (sliding window analysis of consecutive SNPs) was used to identify chromosome regions of interest that remained significant at a false discovery rate of 10%. Subsequently, risk estimates were generated for regions with a high level of signal and individual SNPs by unconditional logistic regression adjusting for age, gender and study center. Three regions containing genes associated with renal cancer were identified: caspase 1/5/4/12(CASP 1/5/4/12), epidermal growth factor receptor (EGFR), and insulin-like growth factor binding protein-3 (IGFBP3). We observed that individuals with CASP1/5/4/12 haplotype (spanning area upstream of CASP1 through exon 2 of CASP5) GGGCTCAGT were at higher risk of renal cancer compared to individuals with the most common haplotype (OR:1.40, 95% CI:1.10–1.78, p-value = 0.007). Analysis of EGFR revealed three strong signals within intron 1, particularly a region centered around rs759158 with a global p = 0.006 (GGG: OR:1.26, 95% CI:1.04–1.53 and ATG: OR:1.55, 95% CI:1.14–2.11). A region in IGFBP3 was also associated with increased risk (global p = 0.04). In addition, the number of statistically significant (p-value<0.05) SNP associations observed within these three genes was higher than would be expected by chance on a gene level. To our knowledge, this is the first study to evaluate these genes in relation to renal cancer and there is need to replicate and extend our findings. The specific regions associated with risk may have particular relevance for gene function and/or carcinogenesis. In conclusion, our evaluation has identified common genetic variants in CASP1, CASP5, EGFR, and IGFBP3 that could be associated with renal cancer risk.

Abstract
BACKGROUND The International Lung Cancer Consortium was established in 2004. To clarify the role of DNA repair genes in lung cancer susceptibility, we conducted a pooled analysis of genetic variants in DNA repair pathways, whose associations have been investigated by at least 3 individual studies. METHODS Data from 14 studies were pooled for 18 sequence variants in 12 DNA repair genes, including APEX1, OGG1, XRCC1, XRCC2, XRCC3, ERCC1, XPD, XPF, XPG, XPA, MGMT, and TP53. The total number of subjects included in the analysis for each variant ranged from 2,073 to 13,955 subjects. RESULTS Four of the variants were found to be weakly associated with lung cancer risk with borderline significance: these were XRCC3 T241M [heterozygote odds ratio (OR), 0.89; 95% confidence interval (95% CI), 0.79-0.99 and homozygote OR, 0.84; 95% CI, 0.71-1.00] based on 3,467 cases and 5,021 controls from 8 studies, XPD K751Q (heterozygote OR, 0.99; 95% CI, 0.89-1.10 and homozygote OR, 1.19; 95% CI, 1.02-1.39) based on 6,463 cases and 6,603 controls from 9 studies, and TP53 R72P (heterozygote OR, 1.14; 95% CI, 1.00-1.29 and homozygote OR, 1.20; 95% CI, 1.02-1.42) based on 3,610 cases and 5,293 controls from 6 studies. OGG1 S326C homozygote was suggested to be associated with lung cancer risk in Caucasians (homozygote OR, 1.34; 95% CI, 1.01-1.79) based on 2,569 cases and 4,178 controls from 4 studies but not in Asians. The other 14 variants did not exhibit main effects on lung cancer risk. DISCUSSION In addition to data pooling, future priorities of International Lung Cancer Consortium include coordinated genotyping and multistage validation for ongoing genome-wide association studies.

Abstract
The global increase in lung cancer burden, together with its poor survival and resistance to classical chemotherapy, underscores the need for identification of critical molecular events involved in lung carcinogenesis. Here, we have applied quantitative profiling of DNA methylation states in a panel of five cancer-associated genes (CDH1, CDKN2A, GSTP1, MTHFR, and RASSF1A) to a large case-control study of lung cancer. Our analyses revealed a high frequency of aberrant hypermethylation of MTHFR, RASSF1A, and CDKN2A in lung tumors as compared with control blood samples, whereas no significant increase in methylation levels of GSTP1 and CDH1 was observed, consistent with the notion that aberrant DNA methylation occurs in a tumor-specific and gene-specific manner. Importantly, we found that tobacco smoking, sex, and alcohol intake had a strong influence on the methylation levels of distinct genes (RASSF1A and MTHFR), whereas folate intake, age, and histologic subtype had no significant influence on methylation states. We observed a strong association between MTHFR hypermethylation in lung cancer and tobacco smoking, whereas methylation levels of CDH1, CDKN2A, GSTP1, and RASSF1A were not associated with smoking, indicating that tobacco smoke targets specific genes for hypermethylation. We also found that methylation levels in RASSF1A, but not the other genes under study, were influenced by sex, with males showing higher levels of methylation. Together, this study identifies aberrant DNA methylation patterns in lung cancer and thus exemplifies the mechanism by which environmental factors may interact with key genes involved in tumor suppression and contribute to lung cancer.

Abstract
Alcohol and tobacco consumption are well-recognized risk factors for head and neck cancer (HNC). Evidence suggests that genetic predisposition may also play a role. Only a few epidemiologic studies, however, have considered the relation between HNC risk and family history of HNC and other cancers. We pooled individual-level data across 12 case-control studies including 8,967 HNC cases and 13,627 controls. We obtained pooled odds ratios (OR) using fixed and random effect models and adjusting for potential confounding factors. All statistical tests were two-sided. A family history of HNC in first-degree relatives increased the risk of HNC (OR=1.7, 95% confidence interval, CI, 1.2-2.3). The risk was higher when the affected relative was a sibling (OR=2.2, 95% CI 1.6-3.1) rather than a parent (OR=1.5, 95% CI 1.1-1.8) and for more distal HNC anatomic sites (hypopharynx and larynx). The risk was also higher, or limited to, in subjects exposed to tobacco. The OR rose to 7.2 (95% CI 5.5-9.5) among subjects with family history, who were alcohol and tobacco users. A weak but significant association (OR=1.1, 95% CI 1.0-1.2) emerged for family history of other tobacco-related neoplasms, particularly with laryngeal cancer (OR=1.3, 95% CI 1.1-1.5). No association was observed for family history of nontobacco-related neoplasms and the risk of HNC (OR=1.0, 95% CI 0.9-1.1). Familial factors play a role in the etiology of HNC. In both subjects with and without family history of HNC, avoidance of tobacco and alcohol exposure may be the best way to avoid HNC.

Abstract
The authors pooled data from 15 case-control studies of head and neck cancer (9,107 cases, 14,219 controls) to investigate the independent associations with consumption of beer, wine, and liquor. In particular, they calculated associations with different measures of beverage consumption separately for subjects who drank beer only (858 cases, 986 controls), for liquor-only drinkers (499 cases, 527 controls), and for wine-only drinkers (1,021 cases, 2,460 controls), with alcohol never drinkers (1,124 cases, 3,487 controls) used as a common reference group. The authors observed similar associations with ethanol-standardized consumption frequency for beer-only drinkers (odds ratios (ORs) = 1.6, 1.9, 2.2, and 5.4 for < or =5, 6-15, 16-30, and >30 drinks per week, respectively; P(trend) < 0.0001) and liquor-only drinkers (ORs = 1.6, 1.5, 2.3, and 3.6; P < 0.0001). Among wine-only drinkers, the odds ratios for moderate levels of consumption frequency approached the null, whereas those for higher consumption levels were comparable to those of drinkers of other beverage types (ORs = 1.1, 1.2, 1.9, and 6.3; P < 0.0001). Study findings suggest that the relative risks of head and neck cancer for beer and liquor are comparable. The authors observed weaker associations with moderate wine consumption, although they cannot rule out confounding from diet and other lifestyle factors as an explanation for this finding. Given the presence of heterogeneity in study-specific results, their findings should be interpreted with caution.

Abstract
Although active tobacco smoking has been identified as a major risk factor for head and neck cancer, involuntary smoking has not been adequately evaluated because of the relatively low statistical power in previous studies. We took advantage of data pooled in the International Head and Neck Cancer Epidemiology Consortium to evaluate the role of involuntary smoking in head and neck carcinogenesis. Involuntary smoking exposure data were pooled across six case-control studies in Central Europe, Latin America, and the United States. Adjusted odds ratios (OR) and 95% confidence interval (95% CI) were estimated for 542 cases and 2,197 controls who reported never using tobacco, and the heterogeneity among the study-specific ORs was assessed. In addition, stratified analyses were done by subsite. No effect of ever involuntary smoking exposure either at home or at work was observed for head and neck cancer overall. However, long duration of involuntary smoking exposure at home and at work was associated with an increased risk (OR for >15 years at home, 1.60; 95% CI, 1.12-2.28; P(trend) < 0.01; OR for >15 years at work, 1.55; 95% CI, 1.04-2.30; P(trend) = 0.13). The effect of duration of involuntary smoking exposure at home was stronger for pharyngeal and laryngeal cancers than for other subsites. An association between involuntary smoking exposure and the risk of head and neck cancer, particularly pharyngeal and laryngeal cancers, was observed for long duration of exposure. These results are consistent with those for active smoking and suggest that elimination of involuntary smoking exposure might reduce head and neck cancer risk among never smokers.

Abstract
We carried out a genome-wide association study of lung cancer (3,259 cases and 4,159 controls), followed by replication in 2,899 cases and 5,573 controls. Two uncorrelated disease markers at 5p15.33, rs402710 and rs2736100 were detected by the genome-wide data (P = 2 x 10(-7) and P = 4 x 10(-6)) and replicated by the independent study series (P = 7 x 10(-5) and P = 0.016). The susceptibility region contains two genes, TERT and CLPTM1L, suggesting that one or both may have a role in lung cancer etiology.

Abstract
PR-6
The conversion of vitamin D to its main biologically active form, 1,25-dihydroxy vitamin D, occurs in the kidney. Since the most biologically active form of vitamin D exerts its activity through binding to the intracellular vitamin D receptor (VDR), most studies of genetic susceptibility have primarily focused on variation within the VDR gene. But, the concert of genes that interact with VDR are vast; therefore, an analysis of genetic variation in VDR and other genes in its pathway may provide insight into the role of vitamin D in renal cell carcinoma (RCC) etiology. In this case-control study, we investigated the relationship between RCC risk and 139 single nucleotide polymorphisms (SNPs) in 8 target genes (VDR, RXRA, RXRB, CYP24A1, GC, STAT1, THRAP4 and TRAP5) of the expanded vitamin D pathway from subjects residing in Central and Eastern Europe. 1,097 RCC cases and 1,476 controls were recruited for this study where genomic DNA was analyzed using an Illumina Oligo Pool-All (OPA) assay. First, the minimum-p-value permutation (Min-P) test was used to identify genes that were associated with RCC risk and that remained significant at a cut off level of 10%. Next, a haplotype-based sliding window analysis of three consecutive SNPs was used to identify chromosome regions of interest that remained significant at a False Discovery Rate (FDR) of 10%. For these regions, haplotype relative risks were computed using the HaploStats package in R. Significant Min-P values were observed for two genes, which were selected for in-depth analysis: VDR (P-value: 0.024) and RXRA (P-value: 0.100). Two chromosomal regions of interest within the VDR gene were identified using the haplotype-based sliding window technique. The first region identified two haplotypes within intron 2, centered around rs4760648, that significantly increased RCC risk (haplotype 1: OR= 1.25; 95% CI= 1.04-1.50 and hapotype 2: OR= 1.26; 95% CI= 1.02-1.54) when compared to patients with the most common referent haplotype. The second signal identified a haplotype (rs886441 and rs12717991) located within intron 4 of the VDR gene that was associated with increased risk among participants with the TG (OR= 1.29; 95%CI= 1.08-1.54) haplotype compared to participants with most common referent haplotype, CA. The global p-values in R for these haplotypes were 0.025 and 0.028, respectively. Across the RXRA gene, a single haplotype located downstream, 3’ of the coding sequence, centered around rs3118523 was shown to increase RCC risk (OR= 1.41; 95% CI= 1.10-1.82) among individuals with the variant haplotype compared to those with the most common haplotype. This is the first study to our knowledge to comprehensively evaluate genetic variation in VDR and other pathway genes in relation to RCC risk. While replication and fine mapping studies will be required to confirm these findings, this study suggests that genes in the vitamin D pathway may modify RCC risk.

Abstract
A89
Recent descriptive studies have reported increases in kidney cancer incidence since the 1970s in the United States and globally. Lipid peroxidation has been suggested as a unifying mechanistic pathway by which several known risk factors including obesity, hypertension, and chemicals directly damage cells of the proximal renal tubules and induce renal carcinogenesis. This study investigated the association between renal cell cancer (RCC) risk and variation in genes that modify the effects of lipid peroxidation, inflammation, and oxidative stress. We conducted a case-control study of RCC (987 cases and 1298 controls) from Central and Eastern Europe and analyzed genomic DNA for 635 single nucleotide polymorphisms (SNPs) thirty-eight candidate genes using an Illumina Oligo Pool-All (OPA). First, the minimum p-value permutation test (MINP) was used to identify genes that remained significant with an FDR<5%. Subsequently, a haplotype-based sliding window analysis of three consecutive SNPs was used to identify chromosome regions of interest that remained significant at a FDR<5%. Six genes were selected for in-depth analysis after multiple testing correction of the single marker associations: APOE, GPX4, NOS2A and PTGS2. The overall gene-level p-values for these genes were 0.017, 0.020, 0.055 and 0.069 using the MINP test, respectively. The minimum FDR-adjusted p-values in a sliding window haplotype analysis were 0.0005, 0.0007, 0.0002 and 1.09x10-5, respectively. For these regions, age-, sex- and center-adjusted haplotype relative risks were computed using the HaploStats package in R. After adjustment, a strong signal centered around the promoter region of APOE gene (rs405509) remained significantly associated with decreased risk of RCC compared to persons homozygous for the referent haplotype (OR=0.73 95% CI:0.59-0.91); global p=0.001). A second haplotype window spanning from IVS7+11 to IVS12-52 of the NOS2A gene that was significantly associated with increased risk (OR=1.36 (95% CI:1.05-1.78); p-global p-0.006). Additional haplotype windows spanning the trans-membrane and tyrosine kinase domains of INSR (rs28601) and intron 2 of LEPR (rs970467) genes also were investigated further (FDR-adjusted p <0.05). After adjustment in Haplostats, two additional high risk haplotypes were identified that were significantly associated with risk. To our knowledge this is the first and largest study of RCC conducted to evaluate these genes in relation to RCC. Although replication and fine mapping studies will be required to confirm these findings, this study supports the hypothesis variation in genes influencing lipid metabolism/peroxidation may increase susceptibility to sporadic kidney cancer.

Abstract
In a case–control study of kidney cancer in four central European countries, with 1097 incident cases and 1476 controls, we found an increased risk for self-reported hypertension and for obesity. Additional unknown risk factors are likely to be responsible for the high rates of kidney cancer in this region.

Abstract
PURPOSE To provide a comprehensive, thorough analysis of somatic mutation and promoter hypermethylation of the von Hippel-Lindau (VHL) gene in the cancer genome, unique to clear cell renal cancer (ccRCC). Identify relationships between the prevalence of VHL gene alterations and alteration subtypes with patient and tumor characteristics. EXPERIMENTAL DESIGN As part of a large kidney cancer case-control study conducted in Central Europe, we analyzed VHL mutations and promoter methylation in 205 well-characterized, histologically confirmed patient tumor biopsies using a combination of sensitive, high-throughput methods (endonuclease scanning and Sanger sequencing) and analysis of 11 CpG sites in the VHL promoter. RESULTS We identified mutations in 82.4% of cases, the highest VHL gene mutation prevalence reported to date. Analysis of 11 VHL promoter CpG sites revealed that 8.3% of tumors were hypermethylated and all were mutation negative. In total, 91% of ccRCCs exhibited alteration of the gene through genetic or epigenetic mechanisms. Analysis of patient and tumor characteristics revealed that certain mutation subtypes were significantly associated with Fuhrman nuclear grade, metastasis, node positivity, and self-reported family history of RCC. CONCLUSION Detection of VHL gene alterations using these accurate, sensitive, and practical methods provides evidence that the vast majority of histologically confirmed ccRCC tumors possess genetic or epigenetic alteration of the VHL gene and support the hypothesis that VHL alteration is an early event in ccRCC carcinogenesis. These findings also indicate that VHL molecular subtypes can provide a sensitive marker of tumor heterogeneity among histologically similar ccRCC cases for etiologic, prognostic, and translational studies.

Abstract
This study investigated associations between occupational pesticide exposure and renal cell carcinoma (RCC) risk. To follow-up on a previous report by Buzio et al., we also considered whether this association could be modified by glutathione S-transferase M1 and T1 (GSTM1 and GSTT1) genotypes. About 1097 RCC cases and 1476 controls from Central and Eastern Europe were interviewed to collect data on lifetime occupational histories. Occupational information for jobs held for at least 12 months duration was coded for pesticide exposures and assessed for frequency and intensity of exposure. GSTM1 and GSTT1 gene deletions were analyzed using TaqMan assays. A significant increase in RCC risk was observed among subjects ever exposed to pesticides [odds ratio (OR): 1.60; 95% confidence interval (CI): 1.00-2.55]. After stratification by genotypes, increased risk was observed among exposed subjects with at least one GSTM1 active allele (OR: 4.00; 95% CI: 1.55-10.33) but not among exposed subjects with two GSTM1 inactive alleles compared with unexposed subjects with two inactive alleles (P-interaction: 0.04). Risk was highest among exposed subjects with both GSTM1 and GSTT1 active genotypes (OR: 6.47; 95% CI: 1.82-23.00; P-interaction: 0.02) compared with unexposed subjects with at least one GSTM1 or T1 inactive genotype. In the largest RCC case-control study with genotype information conducted to date, we observed that risk associated with pesticide exposure was exclusive to individuals with active GSTM1/T1 genotypes. These findings further support the hypothesis that glutathione S-transferase polymorphisms can modify RCC risk associated with occupational pesticide exposure.

Abstract
Alcohol is an important risk factor for upper aerodigestive cancers and is principally metabolized by alcohol dehydrogenase (ADH) enzymes. We have investigated six ADH genetic variants in over 3,800 aerodigestive cancer cases and 5,200 controls from three individual studies. Gene variants rs1229984 (ADH1B) and rs1573496 (ADH7) were significantly protective against aerodigestive cancer in each individual study and overall (P = 10(-10) and 10(-9), respectively). These effects became more apparent with increasing alcohol consumption (P for trend = 0.0002 and 0.065, respectively). Both gene effects were independent of each other, implying that multiple ADH genes may be involved in upper aerodigestive cancer etiology.

Abstract
Tobacco smoke contains an extensive cocktail of highly carcinogenic chemicals. Individuals with a slower elimination rate of the chemicals in tobacco smoke may have increased exposure to their carcinogenic properties compared with those with a faster rate. Polymorphisms that alter the function of the genes involved in the activation or the detoxification of the chemical carcinogens in tobacco smoke can potentially influence an individual's risk of developing a tobacco-related cancer. To test this hypothesis, we have genotyped polymorphisms in 16 genes involved in metabolism of chemical carcinogens in a Central and Eastern European case-control study comprising 2,250 lung cases, 811 upper aerodigestive cancer (UADT) cases, and 2,704 controls. The N-acetyltransferase (NAT) genes were the most implicated in risk, with the NAT1*10 haplotype showing an inverse association in lung cancer, in both heterozygote carriers [odds ratio (OR), 0.81; 95% confidence interval (95% CI), 0.70-0.93] and homozygote carriers (OR, 0.70; 95% CI, 0.48-1.01), suggesting a genotype dose response (P < 0.001). In UADT cancer, a similar inverse association was noted in NAT1*10 although only in heterozygotes (OR, 0.78; 95%CI, 0.65-0.95). In NAT2, when considering the individuals inferred acetylator phenotypes based on their NAT2 diplotype, "slow" acetylators compared with intermediate or fast acetylators showed no association with risk. None of the other 14 genes provided robust evidence of an association for either lung or UADT cancer. We therefore conclude that, of the genetic variation studied, NAT1 gene was the most likely candidate to influence the risk of developing a tobacco-related cancer.

Abstract
The DNA repair systems maintain the integrity of the human genome and cell cycle checkpoints are a critical component of the cellular response to DNA damage. We hypothesized that genetic variants in DNA repair and cell cycle control pathways will influence the predisposition to lung cancer, and studied 27 variants in 17 DNA repair enzymes and 10 variants in eight cell cycle control genes in 1,604 lung cancer patients and 2,053 controls. To improve the estimation of risks for specific variants, we applied a Bayesian approach in which we allowed the prior knowledge regarding the evolutionary biology and physicochemical properties of the variant to be incorporated into the hierarchical model. Based on the estimation from the hierarchical modeling, subjects who carried OGG1 326C/326C homozygotes, MGMT 143V or 178R, and CHEK2 157I had an odds ratio of lung cancer equal to 1.45 [95% confidence interval (95% CI), 1.05-2.00], 1.18 (95% CI, 1.01-1.40), and 1.58 (95% CI, 1.14-2.17). The association of CHEK2 157I seems to be overestimated in the conventional analysis. Nevertheless, this association seems to be robust in the hierarchical modeling. None of the pathways seem to have a prominent effect. In general, our study supports the notion that sequence variation may explain at least some of the variation of inherited susceptibility. In particular, further investigation of OGG1, MGMT, and CHEK2 focusing on the genetic regions where the present markers are located or the haplotype blocks tightly linked with these markers might be warranted.

Abstract
Previous studies investigated the role of vitamin D intake and cancer risk. The kidney is a major organ for vitamin D metabolism, activity, and calcium homeostasis; therefore, it was hypothesized that dietary vitamin D intake and polymorphisms in the vitamin D receptor (VDR) gene may modify renal cell carcinoma (RCC) risk. Three common VDR gene polymorphisms (BsmI, FokI, TaqI) were evaluated among 925 RCC cases and 1192 controls enrolled in a hospital-based case-control study conducted in Central and Eastern Europe. Overall associations with RCC risk were not observed; however, subgroup analyses revealed associations after stratification by median age of diagnosis and family history of cancer. Among subjects over 60 yr, reduced risks were observed among carriers of the f alleles in the FokI single-nucleotide polymorphism (SNP) (odds ratio [OR] = 0.61 for Ff and OR = 0.74 for ff genotypes) compared to subjects with the FF genotype (P trend = 0.04; P interaction = 0.004). Subjects with the BB BsmI genotype and a positive family history of cancer had lower risk compared to subjects with the bb allele (OR = 0.60; 95% CI: 0.33-1.1; P trend = 0.05). Genotype associations with these subgroups were not modified when dietary sources of vitamin D or calcium were considered. Additional studies of genetic variation in the VDR gene are warranted.

Abstract
Poor oral health has been reported as a risk factor in the etiology of head and neck cancer. Data on oral health were ascertained as part of two multicenter case-control studies comprising 924 cases and 928 controls in central Europe and 2,286 cases and 1,824 controls in Latin America. Incident cases of squamous cell carcinoma of the head and neck (oral cavity, pharynx, larynx) and esophagus, as well as age (in quinquennia)- and sex frequency-matched controls, were enrolled from 1998 to 2003. Poor condition of the mouth (central Europe: odds ratio (OR) = 2.89, 95% confidence interval (CI): 1.74, 4.81; Latin America: OR = 1.89, 95% CI: 1.47, 2.42), lack of toothbrush use (Latin America: OR = 2.36, 95% CI: 1.28, 4.36), and daily mouthwash use (Latin America: OR = 3.40, 95% CI: 1.96, 5.89) emerged as risk factors for head and neck cancer, independent of tobacco use and alcohol consumption. Missing between six and 15 teeth was an independent risk factor for esophageal cancer (central Europe: OR = 2.84, 95% CI: 1.26, 6.41; Latin America: OR = 2.18, 95% CI: 1.04, 4.59). These results indicate that periodontal disease (as indicated by poor condition of the mouth and missing teeth) and daily mouthwash use may be independent causes of cancers of the head, neck, and esophagus.

Abstract
Exposure to ionizing radiation (IR) results in various types of DNA damage and is a suspected cause of lung cancer. An essential cellular machinery against DNA damage is cell cycle control, which is regulated by several genes, including TP53, CCND1, and CDKN2A. Therefore, we hypothesized that the genetic variants in these three genes influence the predisposition of lung cancer (i.e., CCND1 G870A, CDKN2A Ala(148)Thr, TP53 Arg(72)Pro, and 16-bp repeat in intron 3) and that the effect of X-ray on lung cancer risk can be modified by the presence of these genetic variations. The study was conducted in 15 centers in 6 countries of Central Europe between 1998 and 2002. A total of 2,238 cases and 2,289 controls were recruited and provided DNA samples. Cases with positive family history were analyzed separately. The joint effect of X-ray and previous risk genotypes was assessed, and modification by sequence variants on X-ray dose-response relationship with lung cancer risk was evaluated. We found an overall effect of TP53 intron 3 16-bp repeats [odds ratio (OR), 1.99; 95% confidence interval (95% CI), 1.27-3.13], which was stronger among cases with family history of lung cancer (OR, 2.98; 95% CI, 1.29-6.87). In addition, our results suggested an interaction that was greater than multiplicativity between TP53 intron 3 16-bp repeats and multiple X-ray exposures (interaction OR, 5.69; 95% CI, 1.33-24.3). We did not observe a main effect of CCND1 G870A polymorphism; however, the dose-response relationship between lung cancer risk and X-ray exposures was modified by CCND1 genotype with no risk from X-ray exposures among subjects who carried G/G genotype, intermediate risk [trend OR for X-ray, 1.16; 95% CI, 1.05-1.27) among subjects with G/A genotype, and highest risk [trend OR for X-ray, 1.29; 95% CI, 1.12-1.49) among subjects with A/A genotype. Sequence variants in cell cycle control pathway may increase the risk of lung cancer and modify the risk conferred by multiple X-ray exposures. However, a definite conclusion can only be drawn on replication by different studies among individuals who are highly exposed to IR.

Abstract
An elevated familial relative risk may indicate either an important genetic component in etiology or shared environmental exposures within the family. Incidence rates of kidney cancer are particularly high in Central Europe, although no data were available on the familial aggregation or genetic background of kidney cancer in this region. We have, therefore, investigated the role of family history in first-degree relatives in a large multicenter case-control study in Central Europe. A total number of 1,097 cases of kidney cancer and 1,555 controls were recruited from 2000 to 2003 from seven centers in Czech Republic, Poland, Romania, and Russia. The risk of kidney cancer increased with the increasing number of relatives with history of any cancer [odds ratio (OR), 1.15; 95% confidence interval (95% CI), 1.00-1.31 per affected relative], and this association seemed to be more prominent among subjects with young onset (OR, 1.55; 95% CI, 1.09-2.20 per affected relative). Overall, the OR was 1.40 (95% CI, 0.71- 2.76) for the subjects who had at least one first-degree relative with kidney cancer after adjusting for tobacco smoking, body mass index, and medical history of hypertension, and this association was most apparent among subjects with affected siblings (OR, 4.09; 95% CI, 1.09-15.4). Based on the relative risk to siblings in our study population, we estimated that 80% of the kidney cancer cases are likely to occur in 20% of the population with the highest genetic risk, which indicate the importance of further investigation of genetic factors in cancer prevention for kidney cancer.

Abstract
Mutations in the tyrosine kinase domain of the epidermal growth factor receptor EGFR are common in non-small cell lung cancer (NSCLC) of never smokers, whereas HER2 mutations are rare. We have analyzed EGFR and HER2 mutations and the expression of the two products of the CDKN2A gene (p14(arf) and p16(INK4a)) in 116 NSCLC that have been previously analyzed for TP53 and KRAS mutations in relation to smoking history of patients. EGFR mutations were detected in 20 of 116 (17%) tumors, whereas five (4.3%) tumors contained HER2 mutations. No tumor contained both mutations. Of tumors with EGFR or HER2 mutation, 72% were adenocarcinomas, 68% were from never smokers, and 32% were from former smokers. EGFR but not HER2 mutations were mutually exclusive with KRAS mutation. Among never smokers, 11 of 16 tumors with EGFR mutation also had TP53 mutation, in contrast with two of 17 tumors without EGFR mutation (P = 0.0008). Expression of p14(arf), but not p16(ink4a), was more frequently down-regulated in never smokers (62.5%) than ever smokers (35%; P = 0.008). All tumors with EGFR or HER2 mutations and wild-type TP53 showed down-regulation of p14(arf) expression. These observations suggest that functional inactivation of the p14(arf)/p53 connection is required in tumors with EGFR or HER2 mutations, consistent with the notion that these proteins are part of a fail-safe mechanism protecting cells against untimely or excessive mitotic signals.

Abstract
OBJECTIVES To investigate the contribution of occupational exposure to asbestos and man-made vitreous fibres (MMVF) to lung cancer in high-risk populations in Europe. METHODS A multicentre case-control study was conducted in six Central and Eastern European countries and the UK, during the period 1998-2002. Comprehensive occupational and sociodemographic information was collected from 2205 newly diagnosed male lung cancer cases and 2305 frequency matched controls. Odds ratios (OR) of lung cancer were calculated after adjusting for other relevant occupational exposures and tobacco smoking. RESULTS The OR for asbestos exposure was 0.92 (95% CI 0.73 to 1.15) in Central and Eastern Europe and 1.85 (95% CI 1.07 to 3.21) in the UK. Similar ORs were found for exposure to amphibole asbestos. The OR for MMVF exposure was 1.23 (95% CI 0.88 to 1.71) with no evidence of heterogeneity by country. No synergistic effect either between asbestos and MMVF or between any of them and smoking was found. CONCLUSION In this large community-based study occupational exposure to asbestos and MMVF does not appear to contribute to the lung cancer burden in men in Central and Eastern Europe. In contrast, in the UK the authors found an increased risk of lung cancer following exposure to asbestos. Differences in fibre type and circumstances of exposure may explain these results.

Abstract
BACKGROUND At least 75% of head and neck cancers are attributable to a combination of cigarette smoking and alcohol drinking. A precise understanding of the independent association of each of these factors in the absence of the other with the risk of head and neck cancer is needed to elucidate mechanisms of head and neck carcinogenesis and to assess the efficacy of interventions aimed at controlling either risk factor. METHODS We examined the extent to which head and neck cancer is associated with cigarette smoking among never drinkers and with alcohol drinking among never users of tobacco. We pooled individual-level data from 15 case-control studies that included 10,244 head and neck cancer case subjects and 15,227 control subjects, of whom 1072 case subjects and 5775 control subjects were never users of tobacco and 1598 case subjects and 4051 control subjects were never drinkers of alcohol. Odds ratios (ORs) and 95% confidence intervals (CIs) were estimated using unconditional logistic regression models. All statistical tests were two-sided. RESULTS Among never drinkers, cigarette smoking was associated with an increased risk of head and neck cancer (OR for ever versus never smoking = 2.13, 95% CI = 1.52 to 2.98), and there were clear dose-response relationships for the frequency, duration, and number of pack-years of cigarette smoking. Approximately 24% (95% CI = 16% to 31%) of head and neck cancer cases among nondrinkers in this study would have been prevented if these individuals had not smoked cigarettes. Among never users of tobacco, alcohol consumption was associated with an increased risk of head and neck cancer only when alcohol was consumed at high frequency (OR for three or more drinks per day versus never drinking = 2.04, 95% CI = 1.29 to 3.21). The association with high-frequency alcohol intake was limited to cancers of the oropharynx/hypopharynx and larynx. CONCLUSIONS Our results represent the most precise estimates available of the independent association of each of the two main risk factors of head and neck cancer, and they exemplify the strengths of large-scale consortia in cancer epidemiology.

Abstract
High consumption of cruciferous vegetables has been associated with reduced kidney cancer risk in many studies. Isothiocyanates, thought to be responsible for the chemopreventive properties of this food group, are conjugated to glutathione by glutathione S-transferases (GSTs) before urinary excretion. Modification of this relationship by host genetic factors is unknown. We investigated cruciferous vegetable intake in 1097 cases and 1555 controls enrolled in a multicentric case-control study from the Czech Republic, Poland, Romania and Russia. To assess possible gene-diet interactions, genotyped cases (N = 925) and controls (N = 1247) for selected functional or non-synonymous polymorphisms including the GSTM1 deletion, GSTM3 3 bp deletion (IVS6 + 22-AGG) and V224I G>A substitution, GSTT1 deletion and the GSTP1 I105V A>G substitution. The odds ratio (OR) for low (less than once per month) versus high (at least once per week) intake of cruciferous vegetables was 1.29 [95% confidence interval (CI): 1.02-1.62; P-trend = 0.03]. When low intake of cruciferous vegetables (less than once per month) was stratified by GST genotype, higher kidney cancer risks were observed among individuals with the GSTT1 null (OR = 1.86; 95% CI: 1.07-3.23; P-interaction = 0.05) or with both GSTM1/T1 null genotypes (OR = 2.49; 95% CI: 1.08-5.77; P-interaction = 0.05). These data provide additional evidence for the role of cruciferous vegetables in cancer prevention among individuals with common, functional genetic polymorphisms.

Abstract
The authors examined the role of diet in the high-risk population of Central Europe among 1,065 incident kidney cancer cases and 1,509 controls in Russia, Romania, Poland, and the Czech Republic. They observed an increased association with kidney cancer for consumption of milk (odds ratio (OR) = 1.46, 95% confidence interval (CI): 1.15, 1.84) and yogurt (OR = 1.34, 95% CI: 1.07, 1.67), as well as all meat (OR = 1.27, 95% CI: 1.06, 1.51 compared with the lowest tertile). High consumption of all vegetables (OR = 0.64, 95% CI: 0.51, 0.80) and cruciferous vegetables (OR = 0.68, 95% CI: 0.55, 0.84) was inversely associated with kidney cancer. In addition, high consumption of preserved vegetables increased the risk of kidney cancer (OR = 1.66, 95% CI: 1.24, 2.21). Alcohol consumption did not appear to be associated with kidney cancer. This 1999-2003 study provides further evidence that diet may play a role in the development of kidney cancer, with a particularly strong protective association for high vegetable intake. The increased risk associated with dairy products, preserved vegetables, and red meat provides clues to the high rates of kidney cancer in this population.

Abstract
Folate has been hypothesized to protect against aero-digestive cancers although the evidence is not yet conclusive due to possible confounding by other dietary factors. Sequence variants in folate pathway were suggested to be associated with plasma folate levels and are unlikely to be confounded by other lifestyle factors. We therefore investigated the effects of key folate genetic variants on the risk of aero-digestive cancers and their potential effect modification by folate intake in a multicenter study in Central Europe. A total of 2250 lung cases, 811 upper aero-digestive tract cases and 2899 controls were recruited with blood samples. The methylenetetrahydrofolate reductase (MTHFR) C677T variant was associated with an increased risk of lung cancer with an odds ratio (OR) for homozygote variant of 1.37 [95% confidence interval (CI) = 1.10-1.71]. The two MTHFR variants were in strong linkage disequilibrium, and 677T-1298A appeared to be the primary haplotype associated with cancer risk. The risk estimates for MTHFR 677T/677T genotype was more prominent among lung cancer patients with young onset (OR = 1.92, 95% CI = 1.12-3.29). When stratified by dietary intake of folate, the effect of the MTHFR 677T variant was more prominent among subjects with low intake of folate: the ORs for 677T/677T genotype among subjects with the lowest decile were 2.60 (95% CI = 1.39-4.88) and 4.14 (95% CI = 1.47-11.7) for lung and upper aero-digestive tract cancer, respectively. In conclusion, we identified a moderate effect of MTHFR C677T on lung cancer risk and a possible effect modification by folate intake that is consistent with the functional data. These results support an important role of folate in protecting against tobacco-related cancers.

Abstract
OBJECTIVE We sought to evaluate the role of occupation and industry in lung carcinogenesis in six countries in Central and Eastern Europe. METHODS This multi-center case-control study included 2,056 male and 576 female lung cancer incidence cases diagnosed from 1998 to 2001 and 2,144 male and 727 female controls frequency-matched for sex and age. Unconditional regression models were applied to calculate the odds ratios after controlling for potential confounders including age (5-year groups), study center (15 centers), and tobacco pack-years. RESULTS Elevated odds ratios (ORs) were found for men employed as production workers (OR 1.45, 95% CI 1.22-1.72), bookkeepers and cashiers (1.81, 1.03-3.24), general farmers (1.67, 1.08-2.60), livestock workers (2.54, 1.09-5.88), miners (2.17, 1.47-3.23), toolmakers and metal patternmakers (2.56, 1.34-4.94), glass formers (2.55, 1.18-5.50), dockworkers, and freight handlers (1.49, 1.04-2.12). Industries with elevated risk among men included mining (1.75, 1.20-2.57), manufacture of cement, lime, or plaster (3.62, 1.11-12.00), casting of metals (2.00, 1.17-3.45), manufacture of electric motors (2.18, 1.24-3.86). For women, elevated ORs were found for medical, dental, veterinary doctors (2.54, 1.01-6.31), librarians and curators (7.03, 1.80-27.80), sewers 3.63 (1.12-10.23). CONCLUSIONS This study identifies new areas for further, explanatory analyses, especially in production work, and indicates new possible sources of exposure to cancer risk for women.

Abstract
CHEK2 is a key cell cycle control gene encoding a pluripotent kinase that can cause arrest or apoptosis in response to unrepaired DNA damage. We report a large case-control study of a non-functional variant that had previously been expected to increase cancer rates. Four thousand and fifteen cancer patients (2250 lung, 811 squamous upper aero-digestive and 954 kidney) and 3052 controls in central Europe were genotyped for the mis-sense variant rs17879961 (replacement of T by C), which changes an amino acid (I157T) in an active site of the gene product. The heterozygous (T/C) genotype was associated with a highly significantly lower incidence of lung cancer than the common T/T genotype [relative risk (RR), T/C versus T/T, 0.44, with 95% confidence interval (CI) 0.31-0.63, P < 0.00001] and with a significantly lower incidence of upper aero-digestive cancer (RR 0.44, CI 0.26-0.73, P = 0.001; P = 0.000001 for lung or upper aero-digestive cancer). Protection was significantly greater for squamous than adenomatous lung cancer (P = 0.001). There was an increase of borderline significance in kidney cancer (RR 1.44, CI 0.99-2.00, P = 0.06). This unexpected halving of tobacco-related cancer (since replicated independently) implies much greater absolute risk reduction in smokers than in non-smokers. The mechanism is unknown: perhaps squamous stem cell apoptosis following smoke exposure causes net harm (e.g. by forcing nearby stem cells to divide before they have repaired their own DNA damage from tobacco smoke). If so, reducing the rate of apoptosis by reducing CHEK2 activity could be protective-although not smoking would be far more so.

Abstract
Incidence rates for laryngeal cancer in Central Europe are among the highest in the world. The authors recruited cases and controls between 2000 and 2002 for the Central and Eastern Europe Multicenter Study to investigate the role of tobacco and alcohol as causes of laryngeal cancer in this region. A total of 384 incident squamous cell cases were included, comprising 254 glottic and 108 supraglottic cancers. Hospital controls were chosen from within the same catchment area, from diseases unrelated to tobacco or alcohol (n = 918). Significant dose-response trends for frequency and duration of tobacco use were observed for both supraglottic and glottic cancers, with potentially a more important effect for supraglottic cancer. Quitting smoking was protective against laryngeal cancers after 5 years. Any increases in risk for alcohol drinking were generally moderate and nonsignificant. A greater than multiplicative interaction was observed between tobacco and alcohol on the risk of laryngeal cancer (p = 0.04). Approximately 87% of laryngeal cancer cases in Central Europe are attributable to tobacco use, of which 75% and 12% are due to current and past smoking, respectively. Approximately 39% are attributable to the interaction between alcohol and tobacco. Preventive efforts to encourage current smokers to quit are likely to be the most effective way to reduce the incidence of laryngeal cancer in this region.

Abstract
OBJECTIVES The purpose of this study was to investigate the role of polymorphisms of genes involved in inflammation in the risk of cancers of the upper aerodigestive tract (UADT). METHODS We have evaluated the role of polymorphisms in key genes related to inflammation, namely IL1B (rs1143627), COX2/PTGS2 (rs5275), and IL8 (rs4073) in a large case-control study comprising 811 UADT cancer cases and 1,083 controls. RESULTS An association was observed for squamous cell carcinoma of the pharynx for a polymorphism in the promoter of the IL1B gene, with an OR of 2.39 (95% CI = 1.19-4.81) for the homozygotes for the minor allele A promoter polymorphism of IL8 was associated with decreased risk of laryngeal cancer, with an OR of 0.70 (95% CI = 0.50-0.98) for carriers of the minor allele. CONCLUSIONS To our knowledge, this is the first report on the role of these polymorphisms with respect to UADT carcinogenesis. Our results suggest that inflammation-related polymorphisms play a role, albeit minor, in the risk of developing cancers of the upper aerodigestive tract.

Abstract
BACKGROUND The role of crystalline silica dust as a possible cause of lung cancer has been controversial. Relatively few large community-based studies have been conducted to investigate the lung cancer risk from exposure to silica at low levels, taking into account potential confounding factors. METHODS Detailed lifestyle and occupational information were collected from 2852 newly diagnosed cases of lung cancer and 3104 controls between 1998 and 2002 in 7 European countries. For each job held, local experts assessed the probability, intensity, and duration of silica exposure. RESULTS Occupational exposure to crystalline silica was associated with an increased risk of lung cancer (odds ratio = 1.37; 95% confidence interval = 1.14-1.65). This risk was most apparent for the upper tertile of cumulative exposure (OR = 2.08; 95% CI = 1.49-2.90; P for trend <0.0001), duration of exposure (1.73; 1.26-2.39; P for trend = 0.0001) and weighted duration of exposure (1.88; 1.35-2.61; P for trend <0.0001). We did not observe any interaction beyond a multiplicative model between tobacco smoking and silica exposure. CONCLUSIONS Our results support the hypothesis that silica is an important risk factor for lung cancer. This risk could not be explained by exposure to other occupational carcinogens or smoking, and it was present for the main histologic types of lung cancer, different sources of silica exposure, and different industrial settings.

Abstract
The role of genes coding for xenobiotic metabolizing enzymes (XMEs) and the risk of lung cancer is unclear. Under the assumption that these genes may be more important among people having a diagnosis of lung cancer at younger ages, we have investigated the role of single-nucleotide polymorphisms (SNPs) within phase I and phase II XME genes, and also genes involved in the metabolism of nucleic acids in a series of young onset patients and matched controls. We genotyped 299 lung cancer cases diagnosed before the age of 50 and 317 controls, from six countries of Central and Eastern Europe, by use of an oligonucleotide microarray and arrayed primer extension technique for 45 SNPs in 15 phase I XME genes, 46 SNPs in 17 phase II genes and 9 SNPs in 4 genes related to metabolism of nucleic acids. Heterozygote carriers of SNPs in CYP1A2 1545T>C, -164C>A and -740T>G; CYP2A6 -47A>C; MDR1 3435T>C; NAT1 1088T>A and 1095A>C; GSTA2 S112T; GSTM3 V224I and MTHFR A222V had altered risk of developing lung cancer. Phenotypes reconstructed after haplotype analyses showed that the carriers of the combined NAT1 fast+ NAT2 fast phenotypes were at lower risk when compared with those with the combined NAT1 slow + NAT2 slow acetylator phenotypes. Finally, extensive EPHX1 metabolizers showed an increased risk as compared with the poor metabolizers.

Abstract
BACKGROUND Tobacco smoking is the main cause for lung cancer worldwide, making it difficult to examine the carcinogenic role of other risk factors because of possible confounding by smoking. Therefore, the present study aimed to investigate the association between lung cancer and occupation independent of smoking. METHODS A case-control study of lung cancer was carried out between March 1998 and January 2002 in 16 centers from 7 European countries, including 223 never-smoking cases and 1039 controls. Information on lifestyle and occupation was obtained through detailed questionnaires. Job and industries were classified as entailing exposure to known or suspected carcinogens; in addition, expert assessment provided exposure estimates to specific agents. RESULTS The odds ratio of lung cancer among women employed for more than 12 years in suspected high-risk occupations was 1.75 (95% confidence interval = 0.63-4.85). A comparable increase in risk was not detected for employment in established high-risk occupations or among men. Increased risk of lung cancer was suggested among individuals exposed to nonferrous metal dust and fumes, crystalline silica, and organic solvents. CONCLUSION Occupations were found to play a limited role in lung cancer risk among never-smokers. Jobs entailing exposure to suspected lung carcinogens should receive priority in future studies among women. Nonferrous metal dust and fumes and silica may exert a carcinogenic effect independently from smoking.

Abstract
Esophageal cancer mortality rates in Central and Eastern Europe have been increasing steadily and are expected to increase further in the future. To evaluate the role of risk factors for esophageal cancer in this population, a multicenter study was conducted, with investigation of tobacco and alcohol as one of the principal aims. We have included 192 squamous cell carcinoma (SCC) and 35 adenocarcinoma cases of the esophagus diagnosed at designated hospitals in 5 centers from Romania, Russia, the Czech Republic and Poland. Controls were frequency matched from patients in the same hospital as the cases (n=1,114). Our results showed that the risk of esophageal SCC may be increased by approximately 7-fold for current smokers (OR=7.41, 95% CI 3.98-13.79) and by 3-fold for ever alcohol drinkers (OR=2.86, 95% CI 1.06-7.74). Dose-response relations were evident for both the frequency and duration of tobacco and of alcohol on the risk of esophageal SCC. Risk estimates for tobacco smoking were highest for lower esophageal SCCs, while risk estimates for alcohol drinking were highest for upper esophageal SCCs; though differences were not statistically significant. For adenocarcinoma of the esophagus, our results suggested a more modest increase in risk because of tobacco smoking than that for SCC of the esophagus and no association with alcohol consumption, although our sample size was small. A synergistic interaction between tobacco and alcohol was observed for the risk of esophageal SCC, highlighting the importance of both factors for esophageal cancers in Central and Eastern Europe.

Abstract
The authors have calculated cumulative risks of lung cancer from a case-control study conducted between 1998 and 2002 involving 2,633 lung cancer cases and 2,884 controls in Hungary, Poland, the Czech Republic, Slovakia, Romania, and Russia. The odds ratios for smoking history were combined with national lung cancer mortality rates to obtain the cumulative risk of lung cancer. The cumulative risk of death from lung cancer by the age of 75 years among current male smokers was 14.6% in Romania and Russia and 15.8% in Poland, similar to levels reported in Western Europe, although higher risks were found in the Czech Republic (19.8%), Hungary (21.9%), and Slovakia (28.2%). Cumulative risks of lung cancer death among never smokers of over 1% were observed in Hungary among both men and women and among men in Poland. The effect of quitting smoking on the lifetime cumulative risk was substantial, with between 67% and 83% of lung cancer risk among men being avoided by quitting before the age of 50 years. This substantial reduction in risk among former smokers confirms that lung cancer mortality in Central Europe over the next three decades will be determined by the extent to which current smokers can successfully quit smoking.

Abstract
Exposure to tobacco smoke and to mutagenic xenobiotics can cause various types of DNA damage in lung cells, which, if not corrected by DNA repair systems, may lead to deregulation of the cell cycle and, ultimately, to cancer. Genetic variation could thus be an important factor in determining susceptibility to tobacco-induced lung cancer with genetic susceptibility playing a larger role in young-onset cases compared with that in the general population. We have therefore studied 102 single-nucleotide polymorphisms (SNP) in 34 key DNA repair and cell cycle control genes in 299 lung cancer cases diagnosed before the age of 50 years and 317 controls from six countries of Central and Eastern Europe. We have found no association of lung cancer risk with polymorphisms in genes related to cell cycle control, single-strand/double-strand break repair, or base excision repair. Significant associations (P < 0.05) were found with polymorphisms in genes involved in DNA damage sensing (ATM) and, interestingly, in four genes encoding proteins involved in mismatch repair (LIG1, LIG3, MLH1, and MSH6). The strongest associations were observed with heterozygote carriers of LIG1 -7C>T [odds ratio (OR), 1.73; 95% confidence interval (95% CI), 1.13-2.64] and homozygote carriers of LIG3 rs1052536 (OR, 2.05; 95% CI, 1.25-3.38). Consideration of the relatively large number of markers assessed diminishes the significance of these findings; thus, these SNPs should be considered promising candidates for further investigation in other independent populations.

Abstract
Cancers of the upper aerodigestive tract (UADT), comprising the oral cavity, pharynx, larynx and oesophagus, account for 5.2% of all cancers cases worldwide. The major risk factors, tobacco and alcohol can directly or indirectly generate DNA damage, which if unrepaired can give rise to mutations, unregulated cell growth and apoptosis induction. To clarify the role of DNA repair and cell cycle control proteins in UADT cancer susceptibility, we studied the risk in relation to 28 SNPs in 18 DNA repair enzymes and 9 SNPs in 7 cell cycle control genes. A case-control study was conducted from 2000 to 2002 in six centers from Romania, Poland, Russia, Slovakia and the Czech Republic. Patients diagnosed with squamous cell carcinoma of the UADT (n=811) and controls with a recent diagnosis of diseases unrelated to tobacco and alcohol (n=1083) were recruited. For UADT cancer risk, associations were observed for the homozygous carriers of the variant alleles of MGMT L84F [odds ratio (OR) 2.35, 95% confidence interval (CI) 1.32-4.20], MGMT 171C > T (OR 2.24, 95% CI 1.20-4.17) and OGG1 S326C (OR 2.07, 95% CI 1.15-3.73) whilst three variants were associated with a protective effect (XPA 23G > A, P for trend 0.022, APEX Q51H, P for trend 0.036, CHEK2 intron 9-200T > C, P for trend 0.009). Several other sequence variants showed associations with specific cancers without an overall association with UADT cancer. While some of these associations are consistent with previous studies, we cannot rule out the possibility of false-positive associations. The positive findings should be explored in another large-scale study on UADT cancers.

Abstract
A multicenter case-control study was conducted during 1999-2002 in four European countries (Poland, Romania, Russia, and Slovakia) to evaluate the role of occupational exposures in risk of laryngeal/hypopharyngeal cancer. Male cancer cases (34 hypopharyngeal, 316 laryngeal) with full data on occupational history and nonoccupational factors were compared with 728 hospital controls for occupational exposure to 73 suspected carcinogens. Occupational history was evaluated by industrial hygienists blinded to case/control status. Elevated risks for ever exposure to coal dust were found for both hypopharyngeal (odds ratio (OR) = 4.19, 95% confidence interval (CI): 1.18, 14.89) and laryngeal (OR = 1.81, 95% CI: 0.94, 3.47) cancer, with clear dose-response patterns. Inclusion of a 20-year lag in the analysis strengthened these associations. Hypopharyngeal cancer risk was also significantly associated with exposure to mild steel dust (OR = 3.04, 95% CI: 1.39, 6.64) and iron compounds and fumes (OR = 2.74, 95% CI: 1.29, 5.84), without clear dose-response relations. Laryngeal cancer was significantly associated with exposure to hard-alloys dust (OR = 2.23, 95% CI: 1.08, 4.57) and chlorinated solvents (OR = 2.18, 95% CI: 1.03, 4.61), without dose-response relations. A possible link between high formaldehyde exposure and laryngeal cancer was suggested. No association was found for exposure to asbestos or inorganic acid mists. These data indicate that occupational exposure to coal dust may play a role in laryngeal and hypopharyngeal cancer. Other possible relations need further evaluation.
