My genes donโt define me. I am AliveAndKickn. Pretty bold statement. AliveAndKickn is more than just a name. Itโs a way of life. I joke that Lynch Syndrome is the genetic predisposition to colon cancer, endometrial cancer, other cancersโฆand soccer. But thatโs just me. Besides half a dozen surgeries since 1997, I have and still play and coach the game I love. …

The GREM1 gene leads to hereditary mixed polyposis syndrome, characterized by multiple polyps of mixed pathology and high risks for colorectal cancer. A specific duplication in the 5′ regulatory region of the GREM1 gene has been found in a subset of Ashkenazi Jewish individuals with hereditary mixed polyposis syndrome; therefore, GREM1 genetic testing is …

A recent study focused on how polygenic risk scores (PRS) may be related to colorectal cancers. Of note, PRS are calculated using genetic differences throughout someoneโs DNA, in combination with their clinical and family history of cancer. PRS, alongside environmental and lifestyle risk factors, may help to identify people who may benefit from screening at …

On June 29, 2020, the FDA approved the use of Keytruda (pembrolizumab), as first-line treatment in unresectable or metastatic, microsatellite instability-high (MSI-H) or mismatch repair-deficient (dMMR) colorectal cancer. Among people with Lynch syndrome, the risk for colorectal cancer (which often has microsatellite instability and/or mismatch-repair deficiency) is raised. Keytruda (pembrolizumab) showed to double the progression-free …

A Polygenic Risk Score (PRS) is calculated using genetic differences throughout someoneโs DNA, in combination with clinical and family history of cancer. This score, alongside environmental and lifestyle risk factors, may help to identify people who might benefit from screening at an earlier age. Important facts about PRS: – It does NOT look for changes …

New colon cancer and polyposis genes recently identified include NTHL1, POLE, POLD1, MSH3, and RNF43. Previous studies suggest these genes raise the risk for colon cancer and polyposis; however, recent data suggest that environmental factors may also play an important role in risk. Ultimately, these genes account for a very small fraction of polyposis cases. …

A worldwide study reporting on cancer risks among individuals with mutations in Lynch syndrome genes showed that there are substantial differences in cancer risks across the various genes.1 Specifically, the risk for colorectal cancer in those with MLH1, MSH2, and MSH6 mutations was substantially higher than what was seen for those with PMS2 mutations. Additionally, …

Individuals with Lynch syndrome have an increased risk of colorectal cancer (CRC) and other cancers. The level of CRC risk is different based on which gene they have a mutation in. Of note, MLH1 and MSH2 carriers have the highest risk of colorectal cancer, generally in the range of 43%-52% by age 70. A recent …

A worldwide study suggests that risks for cancers for the various Lynch syndrome genes have some differences. The risk of colorectal cancer for those with a mutation in the MLH1, MSH2 and MSH6 genes is higher than what is seen for carriers of a PMS2 mutation.

A gene called GALNT12 may be yet another inherited colorectal cancer gene,1 as originally suggested by prior studies.2 The current study screened almost 500 colorectal cancer patients and identified 8 rare variants that may be disease causing. The frequency of variants among colorectal cancer patients was much higher than that observed among population-matched healthy controls, …

Through a randomized trial, patients with FAP were treated with sulindac and erlotinib versus placebo for 6 months. Results of the study showed that those treated with sulindac and erlotinib had 70% fewer polyps than those in the placebo group. The lower number of polyps was seen in both those with an intact colorectum and …

In a study of 51 individuals with multiple colon polyps drawn from 48 families, genetic testing through whole-exome sequencing identified 7 individuals (from 3 unrelated families) to have a mutation in both copies of their NTHL1 gene, and pedigree structure was consistent with autosomal recessive inheritance.1 All these individuals had colorectal cancer and a large …

A recently published phase II clinical trial investigated the use of a new class of drugs (called PD-1 Inhibitors) in DNA mismatch repair-deficient/ microsatellite instability-high colorectal tumors (which are features seen in the majority of colorectal tumors from individuals with Lynch Syndrome) among patients with metastatic disease.1 Investigators found patients who received two PD-1 Inhibitors …

Over the last few years, immunotherapy has emerged as an exciting new class of drugs. As early as 2015, immunotherapy through PD-1 Inhibitors among patients with MSI-H colorectal cancers was shown to be of potential benefit.1 As many individuals with Lynch Syndrome have cancers that are MSI-H and mismatch repair deficient, this class of drugs …
