Assuming a pretest probability of 0.8% for CRC and 10.2% for AN (median prevalence in 7 and 12 studies included in the present meta-analysis, respectively), a positive result increases the probability of CRC to 8.0% and probability of AN to 42.0%. Drafting of the manuscript: Katsoula, Paschos, Tsapas. Critical revision of the manuscript for important intellectual content: All authors. I, Cubiella The pooled test characteristics for CRC were sensitivity, 97% (95% CI, 31%-100%); specificity, 91% (95% CI, 89%-93%); LR+, 10.80 (95% CI, 8.00-14.60); and LR, 0.04 (95% CI, 0.00-2.02). Nearly all of the people who had a follow-up colonoscopy did so within a year of the positive FIT result. Study Selection The average sensitivity of FIT for AN was 48% (95% CI, 39%-57%); and the average specificity was 93% (95% CI, 91%-94%), yielding an LR+ of 6.55 (95% CI, 5.0-8.5) and an LR of 0.57 (95% CI, 0.48-0.67) (GRADE: very low). and P.P.) [This] raises the importance of being able to get the individual steps correct and completed as best you can because every step where you lose some people in follow-up can have a big impact., Study Adds to Debate about Screening for Melanoma, Ivosidenib with Chemotherapy New Option for Some People with AML, If you would like to reproduce some or all of this content, see Reuse of NCI Information for guidance about copyright and permissions. JL, Akl For studies using multiple-sample FIT, positivity was rated based on the highest amount of fecal Hb measured in patient samples. CM, Gatsonis Wong de Wijkerslooth Also, please keep in mind the percentage of positive tests that lead to cancer, I think it's somewhere around 3%. A sample of the stool is placed in a tube or on a card and sent away to the doctor or laboratory for testing. LG, van Rijn G, Huang B, Less than 1 percent of these (601 cases) were advanced cancers. We also searched trial registries and abstracts from relevant scientific meetings, as well as scanned websites of companies manufacturing FITs.

On subsequent colonoscopy, 40% of those with positive tests had either advanced adenomas or cancer. Seven studies were deemed at high or unclear risk of bias.
