“…( Frank et al, 2013 ) PCP who practiced in rural areas, worked in Italian-speaking regions of Switzerland, were over 60, and were male were more likely to be screened with FOBT. ( Braun et al, 2019 , Schneider et al, 2022 ) Like other studies, we found colonoscopy was the preferred screening method for both patients and PCP. ( Hilsden et al, 2005 ).…”

“…42 Colorectal cancer screening (fecal occult blood testing or colonscopy) during the last 2 years in individuals aged 50-75 years increased in the German-speaking part from 34% in 2007 to 48% in 2017. 43 Regarding the potential influence of stage-shift, an earlier publication from the Cancer Registry Zurich has reported the changes in age-standardized incidence rates by stage. 3 There were some increases in lower-staged tumors, for example in prostate cancer, however, a simultaneous increase in stage IV tumors was observed for example in colorectal cancer.…”

BackgroundSurvival trends help to evaluate the progress made to reduce the burden of cancer. The aim was to estimate the trends in 5‐year relative survival of patients diagnosed with breast, prostate, lung, colorectal cancer and skin melanoma in the time periods 1980–1989, 1990–1999, 2000–2009 and 2010–2015 in the Canton of Zurich, Switzerland. Furthermore, we investigated relative survival differences by TNM stage and age group.MethodsData from the Cancer Registry of Zurich was used from 1980 to and including 2015, including incident cases of breast (N = 26,060), prostate (N= 23,858), colorectal (N= 19,305), lung cancer (N= 16,858) and skin melanoma (N= 9780) with follow‐up until 31 December 2020. The cohort approach was used to estimate 5‐year relative survival.ResultsThe 5‐year relative survival increased significantly between 1980 and 1989, and 2010 and2015: from 0.70 to 0.89 for breast, from 0.60 to 0.92 for prostate, from 0.09 to 0.23 (men) and from 0.10 to 0.27 (women) for lung, from 0.46 to 0.66 (men) and from 0.48 to 0.68 (women) for colorectal cancer, and from 0.74 to 0.94 (men) and from 0.86 to 0.96 (women) for skin melanoma. Survival for stage IV tumors was considerably lower compared to lower‐staged tumors for all cancer types. Furthermore, relative survival was similar for the age groups <80 years but lower for patients aged 80 years and older.ConclusionThe observed increasing trends in survival are encouraging and likely reflect raised awareness around cancer, improved diagnostic methods, and improved treatments. The fact that stage I tumor patients have generally high relative survival reflects the efforts made regarding early detection.

“…In Switzerland, the colorectal cancer screening prevalence before the implementation of organised programmes had increased from 33% in 2007 to 48% in 2017, mostly due to the growing use of opportunistic colonoscopy [9]. Colorectal cancer testing rates in Switzerland are higher among those with private insurance coverage and low-deductible health plans, suggesting that reimbursement of tests might increase colorectal cancer screening rates [6].…”

“…The impact of the Vaud programme on colonoscopy and faecal occult blood test testing rates is not known because Vaud does not have universal health records with the screening status of all individuals. In Vaud, as throughout Switzerland, high rates of opportunistic screening existed before the implementation of the screening programme, making isolating its effect more difficult [9].…”

AIMS OF THE STUDY: Canton Vaud, Switzerland, implemented an organised colorectal cancer screening programme with colonoscopy and faecal occult blood tests in 2015, 4 to 6 years ahead of neighbouring cantons. Before its implementation, nearly half of Swiss citizens were already up to date with screening, primarily from opportunistic colonoscopies. We hypothesised that earlier implementation of an organised programme would be associated with greater increases in colorectal cancer testing rates. METHODS: We analysed Swiss health insurance claim data from CSS, a Swiss health insurer covering 16% of the Swiss population and 10% of canton Vaud. We stratified 50–69-year-olds into groups from Vaud, its four neighbouring cantons (Fribourg, Geneva, Neuchâtel and Valais), and the rest of Switzerland. We analysed overall, faecal occult blood test and colonoscopy testing rates for each year between 2010 and 2018. RESULTS: The overall testing rate increased from 7.6% in 2010 to 11.6% in 2018 (+4.0%) in Vaud, from 6.1% to 9.3% (+3.2%) in neighbouring cantons and from 7.4% to 8.6% (+1.2%) in the rest of Switzerland. The faecal occult blood test rate increased between 2016 and 2018 from 2.9% to 4.1% (+1.2%) in Vaud and from 1.7% to 2.6% (+0.9%) in neighbouring cantons, but it decreased from 3.1% to 1.5% (–1.6%) in the rest of Switzerland. The colonoscopy rate increased in all cantons, from 4.7% to 7.5% in Vaud (+2.8%), from 4.4% to 6.7% in neighbouring cantons (+2.3%) and from 4.3% to 7.1% in the rest of Switzerland (+2.8%). By 2018, 40% of faecal occult blood tests and 26% of colonoscopies in Vaud occurred in the organised programme. Those who completed an faecal occult blood test within the Vaud programme were younger, had fewer comorbidities and were more likely to have a high-deductible health plan than those tested outside the programme. CONCLUSIONS: Colorectal cancer testing rates increased between 2010 and 2018, with greater absolute increases in Vaud than in neighbouring cantons or the rest of Switzerland. Faecal occult blood test use increased in both Vaud and neighbouring cantons, possibly reflecting changes in testing patterns by general practitioners. By 2018, 40% of colonoscopies and 26% of faecal occult blood tests occurred within the screening programme.
