BACKGROUND In the Czech Republic, around 6,500 women get breast cancer each year; out of this number, nearly 1,000 women are triple negative subtype. Triple negative breast cancer is characterized by lack of expression of α-estrogen, progesterone, and HER2 receptors. Vast majority of these cases are low-differentiated carcinomas, majority belonging to the basal-like subgroup defined originally ...

background: brca1 and brca2 genes have been recognized to be responsible for 20-30% of hereditary breast can­cers and approximately 50% of familial breast and ovarian cancers. therefore, the demand for brca1 and brca2 muta­tion screening is rapidly increasing as their identification will affect medical management of people at increased risk. because of high costs involved in analysis of brca1 a...

Drs. Levine and Gemignani have provided a comprehensive review of the literature regarding the management of patients with hereditary breast/ovarian cancer syndrome. As noted, over 200,000 new cases of breast cancer and 25,000 new cases of ovarian cancer are estimated for 2003.[1] Only a small portion of these cases will be hereditary; however, these are the cases that may benefit from preventi...

Alias: Familial pancreatic cancer Inheritance It has been estimated that as many as 10% of pancreatic cancers have a hereditary basis; five genetic syndromes have been identified that are associated with the familial aggregation of pancreatic cancer; these include: The second breast cancer syndrome (BRCA2), the familial atypical multiple mole melanoma (FAMMM), the Peutz-Jeghers Syndrome, the he...

PURPOSE The pathogenic CHEK2 1100delC variant is firmly established as a breast cancer susceptibility allele. Dutch CHEK2 1100delC breast cancer families frequently also include colorectal cancer cases, and the variant is particularly prevalent among breast cancer families with hereditary breast and colorectal cancer. Yet, it is still unclear whether CHEK2 1100delC also confers a colorectal can...

Hereditary cancers are thought to account for around 5% of cancers, particularly breast/ovarian and colorectal cancers. In India there is a paucity of data on hereditary cancers and the mutations in some of the common genes linked to hereditary cancers, such as BRCA1, BRCA2, hMSH2 and hMLH1. The country's first comprehensive hereditary cancer clinic was established in February 2002. The article...

641 O ncology is one of the first subspecialties to experience the full impact of the genomics revolution; oncology nurses regularly use genomic science in prevention, screening, diagnostics, prognostics, selection of treatment, and monitoring of treatment effectiveness in cancer care (Mahon, 2009). Genetic tests are now routinely ordered to determine risk for developing and appropriate managem...

BACKGROUND Germline mutations in PALB2 gene make a small contribution to heritable breast cancer susceptibility. A recent report has revealed that women with mutations in the PALB2 gene were more than nine times as likely to develop breast cancer compared to those without. The aim of this study is to understand the status of PALB2 mutations among Chinese high-risk breast cancer patients in a mu...

Breast cancer is the most common cancer in women in developed countries, and the contribution of genetic susceptibility to breast cancer development has been well-recognized. However, a great proportion of these hereditary predisposing factors still remain unidentified. To examine the contribution of rare copy number variants (CNVs) in breast cancer predisposition, high-resolution genome-wide s...
