There is general agreement that when positron emission tomography (PET) incidentally lights up the colon, there is a substantial positive predictive value for cancer and large adenomas. <\/p>\n\n\n\n
The current study is significant primarily for its large size. In the retrospective study from the North Denmark Region, 19,987 patients underwent 18F-fluorodeoxyglucose-PET\/CT from 2006 through 2015, of whom 1,652 had a colonoscopy within 12 months. Incidental colorectal uptake was noted in 623 patients, of whom 74 were excluded, mostly for prior or current known colon cancer (n=68). <\/p>\n\n\n\n
Of the remaining patients, cancer was present in 13.8% and adenoma in 40.3%. The overall positive predictive value for neoplasia was 72%, and the sensitivity for any neoplasia was 57%. <\/p>\n\n\n\n
Ninety-two patients with a PET-avid lesion had a negative colonoscopy; none of these patients developed colorectal cancer during a median follow-up of 7.2 years.<\/p>\n","protected":false},"excerpt":{"rendered":"
