Lung cancer is the most common cause of cancer death worldwide, with over one million cases annually. To identify genetic factors that modify disease risk, we conducted a genome-wide association study by analysing 317,139 single-nucleotide polymorphisms in 1,989 lung cancer cases and 2,625 controls from six central European countries. We identified a locus(More)
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 × 10−7 and P = 4 × 10−6) and replicated by the independent study series (P = 7 × 10−5 and P(More)
BACKGROUND Base excision repair (BER) is a highly conserved essential mechanism for maintaining genome integrity. We examined associations among four well-characterized polymorphisms of BER genes (OGG1 Ser326Cys, XRCC1 Arg194Trp, XRCC1 Arg280His, and XRCC1 Arg399Gln) and lung cancer risk. METHODS A total of 2188 patients with lung cancer and 2198 control(More)
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(More)
An investigation into fine-scale European population structure was carried out using high-density genetic variation on nearly 6000 individuals originating from across Europe. The individuals were collected as control samples and were genotyped with more than 300 000 SNPs in genome-wide association studies using the Illumina Infinium platform. A major(More)
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(More)
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(More)
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(More)
BACKGROUND Recent studies support an important role for human papillomavirus (HPV) in a subgroup of head and neck squamous cell carcinomas (HNSCC). We have evaluated the HPV deoxyribonucleic acid (DNA) prevalence as well as the association between serological response to HPV infection and HNSCC in two distinct populations from Central Europe (CE) and Latin(More)
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(More)
