PURPOSE Because of increasing uptake of cancer genetic testing and the improving survival of young patients with cancer, health care practitioners including oncologists will increasingly be asked about options for assisted reproduction by members of families affected by hereditary cancer syndromes. Among these reproductive options, preimplantation genetic(More)
Invasive lobular breast cancer (ILC) accounts for 10-15% of all invasive breast carcinomas. It is generally ER positive (ER+) and often associated with lobular carcinoma in situ (LCIS). Genome-wide association studies have identified more than 70 common polymorphisms that predispose to breast cancer, but these studies included predominantly ductal (IDC)(More)
At present cancer genetics referrals are reactive to individuals asking for a referral and providing a family history thereafter. A previous pilot study in a single General Practice (GP) catchment area in North London showed a 1.5-fold increase in breast cancer risk in the Ashkenazi Jewish population compared with the non-Ashkenazi mixed population. The(More)
BACKGROUND As genetic testing becomes more common and increasingly intertwined with medical care, the issues of genetic privacy and doctor-patient confidentiality are being examined. Hereditary non-polyposis colorectal cancer (HNPCC) is a genetic predisposition to colorectal and certain other cancers. Effective screening that can prevent colorectal cancer(More)
Ductal carcinoma in situ (DCIS) is a non-invasive form of breast cancer. It is often associated with invasive ductal carcinoma (IDC), and is considered to be a non-obligate precursor of IDC. It is not clear to what extent these two forms of cancer share low-risk susceptibility loci, or whether there are differences in the strength of association for shared(More)
Technological advances in DNA sequencing have made gene testing fast and more affordable. Evidence of effectiveness and cost-effectiveness of genetic service models is essential for the successful translation of sequencing improvements for patient benefit, but remain sparse in the genetics literature. In particular, there is a lack of detailed cost data(More)
A perilymphatic fistula of a labyrinthine window may initially present with various cochlear or vestibular symptoms. Vestibular perilymph leaks can occur spontaneously with or without hearing loss and are most readily diagnosed by a positive Hennebert's sign. Surgical correction is indicated and should initially consist of grafting of the perilymph leak. A(More)
