Hereditary ovarian cancer accounts for at least 5% of the estimated 22,000 new cases of this disease during 2009. During this same time, over 15,000 will die from malignancy ascribed to ovarian origin. The bulk of these hereditary cases fits the hereditary breast-ovarian cancer syndrome, while virtually all of the remainder will be consonant with the Lynch syndrome, disorders which are autosoma...

About 6% of colorectal cancers are caused by genetic mutations associated with hereditary colorectal cancer syndromes. The most common hereditary cancer syndromes nurses are likely to encounter include hereditary nonpolyposis colon cancer or Lynch syndrome, familial adenomatous polyposis, attenuated familial adenomatous polyposis, and MYH polyposis. Current colorectal cancer recommendations for...

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...

Research in genetics has facilitated the identification of highly penetrant genes responsible for a large number of diseases. In the oncology field, genetic counselling and gene testing are focused on the two most common syndromes in familial cancer: hereditary breast and ovarian cancer syndrome (HBOC) and hereditary non-polyposis colorectal cancer or Lynch syndrome (LS). The objective of this ...

BACKGROUND Approximately 5-10% of breast cancers are hereditary. Among hereditary syndromes, Hereditary Breast and Ovarian Cancer Syndrome (HBOC) and Li-Fraumeni Syndrome (LFS) have received the most attention. HBOC is due to mutations in the BRCA1 and BRCA2 genes and is characterized by breast adenocarcinoma and/or epithelial ovarian carcinoma. LFS is associated with germline mutations in TP53...

INTRODUCTION The SCAN cancer genetics workgroup aimed to develop Singapore Cancer Network (SCAN) clinical practice guidelines for referral for genetic evaluation of common hereditary cancer syndromes. MATERIALS AND METHODS The workgroup utilised a modified ADAPTE process to calibrate high quality international evidence-based clinical practice guidelines to our local setting. RESULTS To form...
