Among these, 16.7, 19.4, 9.9 and 15.1% were stage III–IV, respectively (p = 0.34). The cancers detected more than 2.5 years after the last colonoscopy were not more advanced than those diagnosed earlier (p = 0.14). Conclusions: The CRC stage and interval since last colonoscopy were not correlated, which is in conflict with the accelerated adenoma-carcinoma paradigm. We have previously reported that more frequent colonoscopy is not associated with lower incidence of CRC in path_MMR carriers as was expected. In contrast, point estimates showed a higher incidence with shorter intervals between examinations, a situation that may parallel to over-diagnosis in breast cancer screening. Our findings raise the possibility that some CRCs in path_MMR carriers may spontaneously disappear: the host immune response may not only remove CRC precursor lesions in path_MMR carriers, but may remove infiltrating cancers as well. If confirmed, our suggested interpretation will have a bearing on surveillance policy for path_MMR carriers.]]> Wed 26 Oct 2022 14:12:41 AEDT ]]> The "unnatural" history of colorectal cancer in Lynch syndrome: lessons from colonoscopy surveillance https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:42759 Wed 19 Apr 2023 09:40:07 AEST ]]> Colorectal cancer incidences in Lynch syndrome: a comparison of results from the prospective lynch syndrome database and the international mismatch repair consortium https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:51614 Tue 12 Sep 2023 13:49:19 AEST ]]> Leiden Open Variation Database of the MUTYH gene https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:10084 G/p.Tyr179Cys and c.1187G>A/p.Gly396Asp (previously c.494A>G/p.Tyr165Cys and c.1145G>A/p.Gly382Asp). However, for a substantial fraction of the detected variants, the clinical significance remains uncertain, compromising molecular diagnostics and thereby genetic counseling. We have established an interactive MUTYH gene sequence variant database (www.lovd.nl/MUTYH) with the aim of collecting and sharing MUTYH genotype and phenotype data worldwide. To support standard variant description, we chose NM_001128425.1 as the reference sequence. The database includes records with variants per individual, linked to available phenotype and geographic origin data as well as records with in vitro functional and in silico test data. As of April 2010, the database contains 1968 published and 423 unpublished submitted entries, and 230 and 61 unique variants, respectively. This open-access repository allows all involved to quickly share all variants encountered and communicate potential consequences, which will be especially useful to classify variants of uncertain significance.]]> Sat 24 Mar 2018 08:12:40 AEDT ]]> Application of a 5-tiered scheme for standardized classification of 2,360 unique mismatch repair gene variants in the InSiGHT locus-specific database https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:20652 Mon 14 Dec 2020 14:04:44 AEDT ]]>
