The estrogen signal is mediated by the estrogen receptor (ER). The specific role of ER-beta, a second ER, in breast carcinogenesis is not known. A number of association studies have been carried out to investigate the relationship between polymorphic sites in the ESR2 gene and breast cancer risk, however, the results are inconsistent. We searched PubMed, Medline, and Web of Science database (updated to 10 January 2010) and identified 13 relevant case-control studies, and approximately 28 single-nucleotide polymorphisms (SNPs) and one micro-satellite marker were reported in the literature. The median number of study subjects was 776 (range 158-13,550). Three genetic variants [(CA)n, rs2987983, and rs4986938] showed significant overall associations with breast cancer, and rs4986938 was reported twice. Because rs4986938 and rs1256049 were the most extensively studied polymorphisms, we subsequently conducted a meta-analysis to evaluate their relationship with breast cancer risk (9 studies of 10,837 cases and 16,021 controls for rs4986938; 8 studies of 11,652 cases and 15,726 controls for rs1256049). For rs4986938, the women harboring variant allele seemed to be associated with a decreased risk either in the dominant model [pooled OR = 0.944, 95% confidence interval (95% CI) 0.897-0.993, fixed-effects] or in the co-dominant model (AG vs. GG) (OR = 0.944, 95% CI 0.895-0.997, fixed-effects). rs1256049 was not associated with breast cancer risk in any model. Five studies had investigated the effect of haplotypes in the ESR2 gene on breast cancer risk, and four of them had positive outcomes. In summary, the present systematic review suggests that SNP rs4986938 as well as haplotypes in the ESR2 gene might be associated with breast cancer. The need for additional studies examining these issues seems of vital importance.

Multiple lines of evidence suggest that genetic factors modify the cancer risks in carriers of mutations in Mendelian cancer syndromes. We review the latest evidence for genetic modifiers of risk for four Mendelian cancer syndromes. In general, candidate gene studies have not been very successful at identifying modifier genes and most studies have been underpowered, but recently polymorphisms identified through genome wide association studies of unselected cancer patients and controls have been shown to modify cancer risk in studies of large numbers of mutation carriers. This approach has identified two genetic variants that are associated with colorectal cancer risk in Lynch Syndrome, and five polymorphisms that are associated with the risk of breast cancer for BRCA1 and/or BRCA2 mutation carriers. As predicted from the association between these five polymorphisms and risk of estrogen-positive or estrogen-negative breast cancer in the general population, differential associations of these polymorphisms with breast cancer risk were found for BRCA1 and BRCA2 mutation carriers presumably because BRCA1 breast cancer tumors are predominantly ER-negative and are biologically distinct from BRCA2 breast cancers. These findings suggest that studies of mutation carriers may be useful for identifying genetic variants associated with different disease subtypes. The current literature underlies the need for increased international collaboration between individual studies, and the continued recruitment of mutation carriers, in order to reliably estimate and identify the genetic modifiers of risk in Mendelian cancer syndromes.

Knowledge of cancer genetics is advancing our biological understanding of breast, colon, prostate and lung cancers. A family history of any one of these four types of cancer can increase an individual's personal risk to also develop a malignancy. For some families, genetic testing, in combination with genetic counseling, can be a helpful way to identify a hereditary cancer predisposition gene or establish a cancer risk management plan. In this paper, we will review the current state of knowledge surrounding genetic factors influencing breast, colon, prostate and lung cancer.

Proto-oncogene HER2 (also known as erbB-2 or neu) plays an important role in the carcinogenesis and the prognosis of breast cancer. Many epidemiological studies have been conducted to explore the association between the HER2 Ile655Val polymorphism and breast cancer risk. However, inconsistency existed in the results. Therefore, we performed a meta-analysis of 27 published case-control studies including 11,504 cases and 12,538 controls. We assessed the strength of the association by crude odds ratios (ORs) with 95% confidence intervals (CIs) and reached a result that HER2 Ile655Val polymorphism was associated with an increased breast cancer risk in overall populations (for Ile/Val vs. Ile/Ile: OR = 1.05, 95% CI = 1.00-1.12, P = 0.07 for heterogeneity; for the dominant model Ile/Val + Val/Val vs. Ile/Ile: OR = 1.10, 95% CI = 1.01-1.20, P = 0.01 for heterogeneity). In subgroup analysis by ethnicity, we found a significant association among Africans (for Val/Val vs. Ile/Ile: OR = 8.78, 95% CI = 1.94-39.72, P = 0.35 for heterogeneity; for the recessive model Val/Val vs. Ile/Val +Ile/Ile: OR = 8.60, 95% CI = 1.92-38.48, P = 0.31 for heterogeneity) and Asians (for Ile/Val vs. Ile/Ile: OR = 1.18, 95% CI = 1.01-1.39, P = 0.41 for heterogeneity; for the dominant model Val/Val + Ile/Val vs. Ile/Ile: OR = 1.18, 95% CI = 1.01-1.38, P = 0.27 for heterogeneity). In conclusion, our meta-analysis suggests that HER2 Ile 655Val polymorphism may contribute to breast cancer risk.

The International Cancer Genome Consortium (ICGC) was launched to coordinate large-scale cancer genome studies in tumours from 50 different cancer types and/or subtypes that are of clinical and societal importance across the globe. Systematic studies of more than 25,000 cancer genomes at the genomic, epigenomic and transcriptomic levels will reveal the repertoire of oncogenic mutations, uncover traces of the mutagenic influences, define clinically relevant subtypes for prognosis and therapeutic management, and enable the development of new cancer therapies.
