BACKGROUND Male breast cancer patients have a higher risk of developing a second primary cancer, but whether this risk differs according to the family history of breast or ovarian cancers remains to be elucidated. We aimed to determine the effect of a positive family history among men diagnosed with breast cancer on tumour characteristics, treatment, second cancer occurrence and overall surviva...
The overall objectives of this thesis were to increase our understanding of the risk and prognosis of breast cancer using the high risk groups of women with bilateral and familial breast cancer. Data from the Swedish Cancer Register, the Multi-Generation Register and the Cause of Death register was used in Paper I-III to identify women with bilateral cancer and study risk and prognosis of the d...
Population attributable faction (PAF) shows the proportion of the disease that could be prevented if the cause could be removed. PAFs for most types of familial cancer have not been determined. We used the Swedish Family-Cancer Database on 10.2 million individuals and 688,537 parental and 116,741 offspring cancers to calculate familial risks, proportions of affected individuals, and familial PA...
Germline mutations in identified breast cancer susceptibility genes account for less than 20% of Chinese familial breast cancers. Dicer is an essential component of the microRNA-producing machinery; germline mutations of DICER1 have been confirmed in familial pleuropulmonary blastoma, ovarian sex cord-stromal tumors, and other cancers. Low expression of DICER1 is frequently detected in breast c...
Breast cancer is very common worldwide, with 800,000 new cases diagnosed each year [Parkin et al,1999]. Among Taiwanese women, breast cancer is the second most common form of cancer (Cancer Registry Annual Report in Taiwan, 1998-2002) and the fourth leading cause of cancer-related death (Public Health Annual Report in Taiwan, 2002). The risk factors for development of breast cancer in Taiwan, a...
background: breast cancer is the most common malignancy in women. breast cancer type 1 susceptibility gene (brca1) is a tumor suppressor gene, involved in dna damage repair and in 81% of the breast-ovarian cancer families were due to brca1. in some clinically investigated genes, the intragenic marker polymorphism is important and the screening of such mutations is faster by using short tandem r...
BACKGROUND A higher frequency of skewed X chromosome inactivation has been reported in a consecutive series of young patients with breast cancer compared with controls of a similar age. OBJECTIVE To investigate the X inactivation pattern in patients with familial non-BRCA1/BRCA2 breast cancer (n = 272), BRCA1/BRCA2 germline mutations (n = 35), and sporadic breast cancer (n = 292). METHODS X...

Chapter 5 Whole exome sequencing of germline DNA from familial non-BRCA1/2 breast cancer cases with a homogeneous tumour profile 110 Abstract Introduction A large proportion of familial breast cancer susceptibility is still unexplained. Inherited germline mutations in the high-risk BRCA1, BRCA2, and PALB2 genes account for approximately 10 to 20 percent of familial breast cancer risk. The failu...
The BRCA2 gene is mutated in familial breast and ovarian cancer, and its product is implicated in DNA repair and transcriptional regulation. Here we identify a protein, EMSY, which binds BRCA2 within a region (exon 3) deleted in cancer. EMSY is capable of silencing the activation potential of BRCA2 exon 3, associates with chromatin regulators HP1beta and BS69, and localizes to sites of repair f...
