    Abstract: It is well known that certain cancers have shown clustering in socioeconomic groups, but limited data are available on recent results and time trends in such clustering. We determined standardized incidence ratios (SIR) for cancer, adjusted for age, period, region, parity and age at first childbirth among men and women in 6 socioeconomic groups based on the Swedish Family-Cancer Database. Persons had to be identified with the same socioeconomic status in the census of years 1960 and 1970, or of years 1960, 1970 and 1980; the comparison group was all people according to the same censuses. Cancers were followed from years 1970 to 1998 or from 1980 to 1998. Both increased and decreased SIRs were found, and a consistent pattern emerged, although the overall SIRs for cancer did not differ much, the lowest being for farmers (0.8S) and the highest for professional men (1.07) and women (1.11). At individual sites, manual workers were at risk of tobacco-, alcohol- and occupation- and human papilloma virus-related cancers and at a decreased risk at most other cancers. Manual workers and farmers showed an excess of stomach cancer; professionals had an excess of melanoma and squamous cell skin cancer. Male and female SIRs correlated highly for manual and blue-collar workers and for professionals. The overall population- attributable fraction for selected sites was 16.7% for men and 10.9% for women and it was highest, over 50%, for lung cancer in both genders

    Abstract: Familial risks for cancer are important for clinical counseling and understanding cancer etiology. Medically verified data on familial risks have not been available for all types of cancer. The nationwide Swedish Family-Cancer Database includes all Swedes born in 1932 and later (0-to 68-year-old offspring) with their parents, totaling over 10.2 million individuals. Cancer cases were retrieved from the Swedish Cancer Registry up to year 2000. Standardized incidence ratios (SIR) and 95% confidence limits (Cl) were calculated for age-specific familial risk in offspring by an exact proband status. The familial risks for offspring cancer were increased at 24/25 sites from concordant cancer in only the parent, at 20/21 sites from a sibling proband and at 12/12 sites from a parent and sibling proband. The highest SIRs by parent were for Hodgkin's disease (4.88) and testicular (4.26), non-medullary thyroid (3.26), ovarian (3.15) and esophageal (3.14) cancer and for multiple myeloma (3.33). When a sibling was affected, even prostate, renal, squamous cell skin, endocrine, gastric and lung cancer and leukemia showed SIRs in excess of 3.00. The highest cumulative risks were found for familial breast (5.5%) and prostate (4.2%) cancers. We identified reliable familial risks for 24 common neoplasms, most of which lack guidelines for clinical counseling or action level. If, for example, a familial SIR of 2.2 would be use as an action level, counseling would be needed for most cancers at some diagnostic age groups. The present data provide the basis for clinical counseling. (C) 2003 Wiley-Liss, Inc

    Abstract: Several studies have reported associations between multiple cancer types and single-nucleotide polymorphisms (SNPs) on chromosome 5p15, which harbours TERT and CLPTM1L, but no such association has been reported with endometrial cancer. To evaluate the role of genetic variants at the TERT-CLPTM1L region in endometrial cancer risk, we carried out comprehensive fine-mapping analyses of genotyped and imputed SNPs using a custom Illumina iSelect array which includes dense SNP coverage of this region. We examined 396 SNPs (113 genotyped, 283 imputed) in 4,401 endometrial cancer cases and 28,758 controls. Single-SNP and forward/backward logistic regression models suggested evidence for three variants independently associated with endometrial cancer risk (P = 4.9 x 10(-6) to P = 7.7 x 10(-5)). Only one falls into a haplotype previously associated with other cancer types (rs7705526, in TERT intron 1), and this SNP has been shown to alter TERT promoter activity. One of the novel associations (rs13174814) maps to a second region in the TERT promoter and the other (rs62329728) is in the promoter region of CLPTM1L; neither are correlated with previously reported cancer-associated SNPs. Using TCGA RNASeq data, we found significantly increased expression of both TERT and CLPTM1L in endometrial cancer tissue compared with normal tissue (TERT P = 1.5 x 10(-18), CLPTM1L P = 1.5 x 10(-19)). Our study thus reports a novel endometrial cancer risk locus and expands the spectrum of cancer types associated with genetic variation at 5p15, further highlighting the importance of this region for cancer susceptibility.

    Abstract: Purpose: The RAS-RAF-mitogen-activated protein kinase pathways mediate the cellular response to growth signals. In melanocytes, BRAF is involved in cAMP-dependent growth signals. Recently, activating mutations in the BRAF gene, were reported in a large proportion of melanomas. We have studied mutations in the BRAF gene and their association with clinical parameters. Experimental Design: We analyzed exons 1, 11, and 15 of the BRAF gene and exons 1 and 2 of the N-ras gene for mutations in 38 metastatic melanomas by PCR-single-strand conformation polymorphism and direct sequencing. Kaplan-Meier survival and multivariate analyses were used to correlate mutations with various clinical parameters. Results: Mutations in exon 15 of the BRAF gene were detected in 26 (68%) melanomas. In 25 cases, mutation involved the "hot spot" codon 600(2) of the BRAF gene. Three melanomas without a BRAF mutation carried amino acid substituting base changes at codon 61 of the N-ras gene. In a multivariate proportional hazard (Cox) model, BRAF mutation, along with the stage of metastatic melanomas, showed a statistically significant hazard ratio of 2.16 (95% confidence interval 1.02-4.59; chi(2) for the model 6.94, degrees of freedom 2, P = 0.03) for diminished duration of response to the treatment. In a Kaplan-Meier survival model, cases with BRAF mutation showed longer disease-free survival (median of 12 months) than cases without mutation (median of 5 months), although this association was not statistically significant (Log-rank test P = 0.13). Conclusions: Our results, besides confirming the high frequency of BRAF mutations in metastatic melanomas, also underline the potential importance of these mutations in disease outcome

    Abstract: Familial risks for cancer are important for clinical counseling and understanding cancer etiology. The nationwide Swedish Family-Cancer Database includes all Swedes born in 1932 and later (0 to 68-year-old offspring) with their parents, totaling over 10.2 million individuals. Urological cancer cases were retrieved from the Swedish Cancer Registry up to year 2000. Standardized incidence ratios (SIR) and 95% confidence limits (CI) were calculated for age-specific familial risk in offspring by an exact proband status. The familial risks for offspring cancer were increased at all urological sites from concordant cancer in the parent and in a sibling proband. The highest SIRs by parent were for testicular and prostate cancer (4.26 and 2.45). When a sibling was affected, even kidney cancer (4.74) showed a high SIR. For kidney cancers, and also for prostate and testicular cancers, the SIRs were higher among siblings than among offspring and parents, which may indicate the involvement of recessive effects. Family members of patients with prostate cancer or von Hippel Lindau disease can expect organized clinical counseling, but family members of patients with other urological cancers are probably not counseled. Guidelines for clinical counseling or action level should be developed for all urological cancers because of the established familial risks. Urological cancers also offer a challenge to molecular geneticists attempting to identify the susceptibility genes underlying the familial clustering

    Abstract: Genome-wide association studies (GWAS) have identified seven breast cancer susceptibility loci, but these explain only a small fraction of the familial risk of the disease. Five of these loci were identified through a two-stage GWAS involving 390 familial cases and 364 controls in the first stage, and 3,990 cases and 3,916 controls in the second stage(1). To identify additional loci, we tested over 800 promising associations from this GWAS in a further two stages involving 37,012 cases and 40,069 controls from 33 studies in the CGEMS collaboration and Breast Cancer Association Consortium. We found strong evidence for additional susceptibility loci on 3p (rs4973768: per-allele OR 1.11, 95% CI = 1.08-1.13, P = 4.1 x 10(-23)) and 17q (rs6504950: per-allele OR 0.95, 95% CI = 0.92-0.97, P = 1.4 x 10(-8)). Potential causative genes include SLC4A7 and NEK10 on 3p and COX11 on 17q

    Abstract: PURPOSE We tested the hypotheses that CHEK2*1100delC heterozygosity is associated with increased risk of early death, breast cancer-specific death, and risk of a second breast cancer in women with a first breast cancer. PATIENTS AND METHODS From 22 studies participating in the Breast Cancer Association Consortium, 25,571 white women with invasive breast cancer were genotyped for CHEK2*1100delC and observed for up to 20 years (median, 6.6 years). We examined risk of early death and breast cancer-specific death by estrogen receptor status and risk of a second breast cancer after a first breast cancer in prospective studies. Results CHEK2*1100delC heterozygosity was found in 459 patients (1.8%). In women with estrogen receptor-positive breast cancer, multifactorially adjusted hazard ratios for heterozygotes versus noncarriers were 1.43 (95% CI, 1.12 to 1.82; log-rank P = .004) for early death and 1.63 (95% CI, 1.24 to 2.15; log-rank P 〈 .001) for breast cancer-specific death. In all women, hazard ratio for a second breast cancer was 2.77 (95% CI, 2.00 to 3.83; log-rank P 〈 .001) increasing to 3.52 (95% CI, 2.35 to 5.27; log-rank P 〈 .001) in women with estrogen receptor-positive first breast cancer only. CONCLUSION Among women with estrogen receptor-positive breast cancer, CHEK2*1100delC heterozygosity was associated with a 1.4-fold risk of early death, a 1.6-fold risk of breast cancer-specific death, and a 3.5-fold risk of a second breast cancer. This is one of the few examples of a genetic factor that influences long-term prognosis being documented in an extensive series of women with breast cancer.

    Abstract: Breast cancer is the most common cancer among women. Common variants at 27 loci have been identified as associated with susceptibility to breast cancer, and these account for similar to 9% of the familial risk of the disease. We report here a meta-analysis of 9 genome-wide association studies, including 10,052 breast cancer cases and 12,575 controls of European ancestry, from which we selected 29,807 SNPs for further genotyping. These SNPs were genotyped in 45,290 cases and 41,880 controls of European ancestry from 41 studies in the Breast Cancer Association Consortium (BCAC). The SNPs were genotyped as part of a collaborative genotyping experiment involving four consortia (Collaborative Oncological Gene-environment Study, COGS) and used a custom Illumina iSelect genotyping array, iCOGS, comprising more than 200,000 SNPs. We identified SNPs at 41 new breast cancer susceptibility loci at genome-wide significance (P 〈 5 x 10(-8)). Further analyses suggest that more than 1,000 additional loci are involved in breast cancer susceptibility.
