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 ]]> Improving adherence to colorectal cancer surveillance guidelines: results of a randomised controlled trial https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:30968 Wed 19 Jan 2022 15:15:50 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 ]]> Comparing theory and non-theory based implementation approaches to improving referral practices in cancer genetics: a cluster randomised trial protocol https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:36129 Wed 17 Nov 2021 16:30:50 AEDT ]]> Costs and cost-effectiveness of targeted, personalized risk information to increase appropriate screening by first-degree relatives of people with colorectal cancer https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:36186 Wed 17 Nov 2021 16:28:40 AEDT ]]> Improving adherence to surveillance and screening recommendations for people with colorectal cancer and their first degree relatives: A randomized controlled trial https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:14000 Wed 11 Apr 2018 15:52:05 AEST ]]> Effect of aspirin or resistant starch on colorectal neoplasia in the Lynch syndrome https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:4498 Wed 11 Apr 2018 15:42:17 AEST ]]> Can a print-based intervention increase screening for first degree relatives of people with colorectal cancer?

Methods: The Prospective Lynch Syndrome Database (PLSD) that records outcomes of surveillance was examined to determine survival after colon cancer in relation to the time since previous colonoscopy and pathological stage. Only path_MMR variants scored by the InSiGHT variant database as class 4 or 5 (clinically actionable) were included in the analysis. Results: Ninety-nine path_MMR carriers had no cancer prior to or at first colonoscopy, but subsequently developed colon cancer. Among these, 96 were 65 years of age or younger at diagnosis, and included 77 path_MLH1, 17 path_MSH2, and 2 path_MSH6 carriers. The number of cancers detected within < 1.5, 1.5–2.5, 2.5–3.5 and at > 3.5 years after previous colonoscopy were 9, 43, 31 and 13, respectively. Of these, 2, 8, 4 and 3 were stage III, respectively, and only one stage IV (interval 2.5–3.5 years) disease. Ten-year crude survival after colon cancer were 93, 94 and 82% for stage I, II and III disease, respectively (p < 0.001). Ten-year crude survival when the last colonoscopy had been < 1.5, 1.5–2.5, 2.5–3.5 or > 3.5 years before diagnosis, was 89, 90, 90 and 92%, respectively (p = 0.91). Conclusions: In path_MLH1 and path_MSH2 carriers, more advanced colon cancer stage was associated with poorer survival, whereas time since previous colonoscopy was not. Although the numbers are limited, together with our previously reported findings, these results may be in conflict with the view that follow-up of path_MMR variant carriers with colonoscopy intervals of less than 3 years provides significant benefit.]]> Thu 27 Oct 2022 09:15:48 AEDT ]]> Experiences of colorectal cancer patients in the 2-years post-diagnosis and patient factors predicting poor outcome https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:27926 Thu 09 Dec 2021 11:02:56 AEDT ]]> Cancer Prevention with Resistant Starch in Lynch Syndrome Patients in the CAPP2-Randomized Placebo Controlled Trial: Planned 10-Year Follow-up https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:51479 Thu 07 Sep 2023 10:53:30 AEST ]]> Long-term effect of aspirin on cancer risk in carriers of hereditary colorectal cancer: an analysis from the CAPP2 randomised controlled trial https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:13923 Sat 24 Mar 2018 08:24:50 AEDT ]]> Obesity, aspirin, and risk of colorectal cancer in carriers of hereditary colorectal cancer: a prospective investigation in the CAPP2 study https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:26262 Sat 24 Mar 2018 07:40:14 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 ]]>
