Pathology of breast cancer in women with constitutional CHEK2 mutations

Abstract: The power of association studies between polymorphic genetic variants and breast cancer may be enhanced if the cancer subjects are subclassified by histologic subgroup. In this study we classified 482 unselected breast cancers from Szczecin, Poland by histology (ductal, lobular, medullary, other). All women were genotyped for three founder mutations in the CHEK2 gene (1100delC, IVS2 + 1G > A and I157T). There was no significant overall association between CHEK2 and breast cancer (OR = 1.3; p = 0.30), but among… Show more

“…As far as the histological subtype is concerned, no correlation has been found with the germ line CHEK2 1100delC variant that is the most frequent in the North of Europe. However, it has been published that in Poland, where there are two other founder variants with higher prevalence than 1100delC, the I157T mutation is associated with the lobular carcinoma subtype (Huzarski et al, 2005). This is the first report demonstrating how different mutations of the same gene may be associated with specific histological subtypes of cancer.…”

“…4% of patients selected from families with at least three cases of breast cancer diagnosed before the age of 60 years (Oldenburg et al, 2003) and 2-8% (Vahteristo et al, 2002;de Bock et al, 2004;Huzarski et al, 2005;Kilpivaara et al, 2005) in unselected breast cancer patients from the North of Europe (Netherlands, Finland, Poland). However, in other countries, this frequency is much lower or null (Offit et al, 2003;Caligo et al, 2004;Osorio et al, 2004;Jekimovs et al, 2005;Kleibl et al, 2005;Rashid et al, 2005).…”

“…A protein-truncating mutation in the gene, 1100delC, was associated with a two-fold increase in breast cancer risk in the CHEK2 Breast Cancer Case -Control Consortium pooling project, which comprised 10 860 breast cancer cases and 9065 controls from 10 studies in five countries (The CHEK2 Breast Cancer Case -Control Consortium, 2004). The prevalence of the CHEK2*1100delC variant among women with and without breast cancer varies among countries (Meijers-Heijboer et al, 2002;Vahteristo et al, 2002;Osorio et al, 2004;Huzarski et al, 2005;Kilpivaara et al, 2005;Bernstein et al, 2006;Weischer et al, 2007).…”

“…Показано, что при раке молочной железы мутации в гене CHEK2 варьируют от 2% до 12% [69][70][71][72]. Кроме невысокого процента выявления этого маркера при раке молочной железы, необходимо отметить, что мутации в гене CHEK2 выявляются также при колоректальном раке [73].…”
