The differences of the mean cumulative risks between hMLH1 carriers and hMSH2 mutation carriers had all no statistically significance in developing all HNPCC-related tumors(p>0.05). 4. The rate of onset for tumors of the members with cancer is higher significantly than that of the members ...
The colon cancers caused by Lynch syndrome tend to be more common on the right side of colon and develop much more quickly than in the general population (1 to 2 years versus 10 years). In addition, patients who have a colorectal cancer have a significantly increased risk of developing a ...
In individuals with Lynch syndrome the following life time risks for cancer are seen: 52%-82% for colorectal cancer (mean age at diagnosis 44-61 years); 25%-60% for endometrial cancer in women (mean age at diagnosis 48-62 years); 6% to 13% for gastric cancer (mean age at diagnosis ...
Female non-carriers had very low lifetime risk for these two outcomes while male non-carriers had lifetime risks intermediate to the female carriers and non-carriers. Female carriers had a lifetime risk of developing EC of 82.4%. Relative risks for developing any HNPCC cancer (carriers relative...

Are there other colon risks associated with Lynch syndrome? Individuals with Lynch syndrome may develop a few colorectal polyps, called adenomas, in the colon or rectum. If these polyps are not detected and removed, they could develop into a cancer. Having regular screeningcolonscopiesis important...

The identification of germline MMR mutations has no major consequence on the cancer treatments, but influences markedly the long-term follow-up and the management of at-risk relatives. Gene carriers will enter a follow-up program regarding their colorectal and endometrial cancer risks, but other ...
