TY - JOUR T1 - Colorectal cancer screening is cost-effective in the elderly who have had less intense prior screening, high baseline risk of colorectal cancer and less comorbidities JF - Evidence Based Medicine JO - Evid Based Med SP - 182 LP - 182 DO - 10.1136/ebmed-2015-110359 VL - 21 IS - 5 AU - Mark Jenkins Y1 - 2016/10/01 UR - http://ebm.bmj.com/content/21/5/182.abstract N2 - Commentary on: van Hees F, Saini SD, Lansdorp-Vogelaar I, et al. Personalizing colonoscopy screening for elderly individuals based on screening history, cancer risk, and comorbidity status could increase cost effectiveness. Gastroenterology 2015;149:1425–37OpenUrlCrossRefPubMed.Eligibility for colorectal cancer screening programmes is usually age-based from 50 to 74 years; the sector of the population in which most disease occurs and, on average, the sector standing to gain most from prevention/early detection. However, given colorectal cancer risk is affected by many factors, a wide spectrum of colorectal cancer risk exists meaning that many within this age range will be at low risk (therefore over screened) and many outside this age range will be at high risk (therefore under screened). What if precision public health approaches were possible where the age cut-offs were substituted by risk or cost-effectiveness thresholds and personalised colorectal cancer risk was calculated taking into account a range of … ER -
