Objectives: In two large university affiliated healthcare systems, we examined trends in colorectal cancer (CRC) screening both prior to and during the COVID-19 pandemic to compare the trends in non-invasive screening tests and colonoscopy.
Materials And Methods: In this retrospective time-trend analysis, we obtained the numbers of colonoscopies and non-invasive tests performed monthly during the pandemic and the year prior to it. We obtained colonoscopy data from five endoscopy units with the indication determined by dual independent review.
Objective: To describe trends in the use of non-invasive tests (NIST) and the interval between a positive NIST and diagnostic colonoscopy.
Methods: Using a retrospective time-trend design, we examined medical records of patients within two large Indiana integrated healthcare systems who had a positive NIST between January 2019 and June 2021 and quantified the proportion of patients who had not completed colonoscopy within 60, 90, and 180 days to determine the interval between NIST result and diagnostic colonoscopy in days.
Results: Of 1379 patients with positive NISTs, 930 (68 %) underwent diagnostic colonoscopy during the 30-month study timeframe.
Background And Aims: The multitarget stool DNA (mt-sDNA) assay is a noninvasive average-risk colorectal cancer (CRC) screening test. A new biomarker panel was developed for a next-generation test to improve specificity while maintaining/increasing sensitivity. We aimed first to establish an algorithm and cutoff for the next-generation mt-sDNA test and then to validate it using archived samples from the pivotal DeeP-C study (NCT01397747) of the first-generation test.
