PURPOSE Lynch syndrome is a cancer predisposition syndrome which includes colon cancer. It is caused by inherited defects in DNA mismatch repair genes. Sporadic colon cancers are influenced by exogenous hormones (e.g., postmenopausal hormones); we hypothesized that polymorphisms which influence endogenous hormones would therefore modify age at colon cancer onset among Lynch syndrome mutation ca...
Background A patient's medical history and familial cancer history are important information for assessing the risk of hereditary cancer. We have generated a self-administered questionnaire for patients with gynecologic cancer. This pilot study analyzed the usefulness of this questionnaire and the rates of patients that meet the Society of Gynecologic Oncology criteria in ovarian cancer and end...
Lynch syndrome is a hereditary cancer syndrome caused by a constitutional mutation in one of the mismatch repair genes. The implementation of predictive testing and targeted preventative surveillance is hindered by the frequent finding of sequence variants of uncertain significance in these genes. We aimed to determine the pathogenicity of previously reported variants (c.-28A>G and c.-7C>T) wit...
Lynch syndrome (clinically referred to as HNPCC - Hereditary Non-Polyposis Colorectal Cancer) is a frequent, autosomal, dominantly-inherited cancer predisposition syndrome caused by various germline alterations that affect DNA mismatch repair genes, mainly MLH1 and MSH2. Patients inheriting this predisposition are susceptible to colorectal, endometrial and other extracolonic tumors. It has rece...
Assessing and addressing ongoing information and support needs among individuals with Lynch syndrome
Background In 2008, Lynch syndrome patients requested referrals to a support organization, prompting the authors to assess available resources. While general information about Lynch syndrome was readily available from multiple sources including the internet, updated, detailed information and psychosocial support was largely unavailable. Based on patient responses to a subsequent needs assessmen...
BACKGROUND Patients with Lynch Syndrome, the most common hereditary colorectal cancer syndrome, benefit from genetic education and family counseling regarding diagnostic testing and cancer surveillance/prevention recommendations. Although genetic counseling is currently the most common venue where such education and counseling takes place, little is known about the level of disease knowledge an...
BACKGROUND/AIMS Early-onset colorectal cancers are relatively rare. About 20% of colorectal cancers are familial or hereditary. Two autosomal dominantly inherited cancer syndromes are more studied: Lynch syndrome accounts for 2-5% of colorectal cancers and familial adenomatous polyposis represents 1% of total colorectal cancers. Unlike the familial adenomatous polyposis syndrome, there are no c...
Background It is known that metachronous colorectal cancer risk for Lynch syndrome patients with primary colon cancer is high and total colectomy is the preferred option [1]. However if the index primary cancer is in the rectum, management advice is complicated by considerations of worsening bowel function or stoma formation. To aid surgical decision-making, we estimated the risk of metachronou...
Mortality from colorectal cancer can be reduced by early diagnosis and by cancer prevention through polypectomy. These NCCN Guidelines for Colorectal Cancer Screening describe various colorectal screening modalities and recommended screening schedules for patients at average or increased risk of developing colorectal cancer. In addition, the guidelines provide recommendations for the management...
