A range of cancers is associated with the rs6983267 marker on chromosome 8.

Several genome-wide searches for common cancers have lead to the identification of a small number of loci that harbor low-risk cancer susceptibility markers. One marker, rs6983267 on chromosome 8q24, has been linked to both colon and prostate cancer, and is therefore a good candidate for a multicancer susceptibility marker. To determine the range of cancer sites associated with rs6983267, we genotyped 7,665 cases of cancer, representing 11 common cancer sites, and 1,910 controls.

Lung cancer susceptibility locus at 5p15.33.

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.

Genetic contribution to all cancers: the first demonstration using the model of breast cancers from Poland stratified by age at diagnosis and tumour pathology.

The aim of the study is to verify the hypothesis that genetic polymorphisms are associated with the predisposition to all malignancies. Using as a model breast cancers from the homogenous Polish population (West Pomeranian region) after stratification of 977 patients by age at diagnosis (under 51 years and above 50 years) and by tumour pathology (ductal cancers--low and high grade, lobular cancers, ER-positive/negative) we tested this hypothesis. Altogether 20 different groups of breast cancer cases have been analyzed.

CHEK2 germline mutations correlate with recurrence rate in patients with superficial bladder cancer.

Background: Some bladder cancers can be the result of genetic predisposition or chromosomal abnormalities, but no clinical useful molecular marker exists to identify patients with higher risk ofrecurrence. We analyzed the recurrence rate in patients with three variants of tumor suppressor gene mutation, checkpoint kinase 2 (CHEK2). The endpoint of the study was to evaluate the rate, risk of recurrence and free-recurrence survival during 24-months observation time in CHEK2 positive (CHEK2+) and control group.
