Lynch syndrome, also called hereditary nonpolyposis colorectal cancer or HNPCC, is a genetic condition that increases the risk of colon and other cancers.

CONCLUSIONS: A simplified pedigree is acceptable for selecting candidates to screen for hereditary colorectal cancer, whereas an extended pedigree is still required for a more precise diagnosis of Lynch syndrome, especially in younger patients.

Introduction: Lynch syndrome or hereditary non-polyposis colon cancer (HNPCC) is inherited disorder in DNA mismatch repair genes which lead to microsatellite instability and increased risk of developing such cancers as colorectal, gastric, endometrial and others in relatively young adults under 50 years of age. Since genes who account for this syndrome have been identified and are transferred to next generations, many countries have launched a screening programme for selected patient groups to carry out prevention strategies.

CONCLUSIONS: The age of onset of sessile serrated adenomas/polyps varies, but the pattern is consistent with increasing methylation in the mucosa. Early negative colonoscopies predict a low risk of methylator cancers. See Video Abstract at http://links.lww.com/DCR/A736.

CONCLUSION: The combination of an increasing incidence of colorectal cancer in those under 50 years of age and the predominance of left-sided cancer suggests that screening by flexible sigmoidoscopy starting at age 40 in average-risk individuals may prevent cancer by finding asymptomatic lesions.

Familial Colorectal Cancer Type X (FCCTX) is a type of hereditary nonpolyposis colorectal cancer in accordance to Amsterdam criteria-1 for Lynch syndrome, with no related mutation in mismatch repair gene. FCCTX is microsatellite stable and is accounted for 40% of families with Amsterdam criteria-1 with a high age of onset. Thus, the carcinogenesis of FCCTX is different compared to Lynch syndrome. In addition to the microsatellite stability and the presence of less predominant tumors in proximal colon, various clinical features have also been associated with FCCTX in comparison with Lynch syndrome such as no increased risk ...

Authors: Abstract Ovarian cancer is the second most common type of female reproductive cancer, and more women die from ovarian cancer than from cervical cancer and uterine cancer combined. Currently, there is no strategy for early detection of ovarian cancer that reduces ovarian cancer mortality. Taking a detailed personal and family history for breast, gynecologic, and colon cancer facilitates categorizing women based on their risk (average risk or high risk) of developing epithelial ovarian cancer. Women with a strong family history of ovarian, breast, or colon cancer may have hereditary breast and ovarian canc...

In a recent note, I discused some theories about why the incidence of colonic cancer is increasing in younger patients (see:Why the Increased Incidence of Colonic Cancer Among Younger Americans?). Continuing in this same vein, a recent article I came across raised the issue of multigene panel testing to reveal genetic mutations in the roughly one-third of patents with early onset colonic cancer (see:Multigene Panel Testing Reveals Mutations in One-Third of Early Onset CRC Patients). Below is an excerpt from the article:Although the overall incidence of colorectal cancer (CRC) has been decreasing in the Unite...

Conclusions: The CCFR has shed light on many environmental factors, genetics and tumor characteristics that are related to both incidence and survival. Information gained from studies using this resource provides insight into the biology of this common cancer and importantly may help target messaging on prevention, inform the development of interventions, or tailor recommendations for CRC survivorship care. The greater scientific community has access to this rich resource.Citation Format: Polly A. Newcomb.

Conclusions We developed a high-throughput deep sequencing approach for concomitant MSI and mutational analyses in FFPE specimens. We provided novel insights into clinically relevant alterations in MSI CRC and a rationale for targeting ERBB2/HER2 mutations in Lynch and Lynch-like CRC.

By Stacy Simon Colon cancer is one of the more common cancers in the US. About 1 in 20 Americans will develop colon cancer at some point during their lifetime. But there are things you can do to help lower your colon cancer risk. Here are 6 ways to help protect your colon health. Get screened for colon cancer. Screenings are tests that look for cancer before signs and symptoms develop. Colon screenings can often find growths called polyps that can be removed before they turn into cancer. These tests also can find colon cancer earlier, when treatments are more likely to be successful. The American Cancer Society recommend...
