4034 Background: Colorectal cancer screening must be repeated on a regular basis. Understanding patient perceptions and willingness to be rescreened will help to determine future compliance rates. The purpose of this study was to compare National CT Colonography Trial (NCTCT) screening participant experiences with CT colonography (CTC) and optical colonoscopy (OC), willingness to return for each procedure, and procedure preference. Methods: NCTCT participants underwent a single bowel preparation (BP). Participants were scheduled to receive CTC, followed by sedation and OC. Participants were asked to complete a questionnaire two weeks post-exam on physical discomfort and embarrassment during BP, CTC and OC and willingness to repeat CTC and OC (with or without BP) at different time intervals. McNemar's Test and logistic regression were used for statistical analysis. Results: 2310 of 2600 patients (89%) responded (1224 women, 1086 men). Mean age was 58.39 years (range 50–86). The participant population was 85% Caucasian, 11% African American and 4% other. Severe discomfort was reported by 7.1% participants with BP, 6.3% with CTC, and 2.2% with OC. Severe embarrassment was reported by 1.6% participants with BP, 1.3% with CTC, and 0.7% with OC. Forty-six percent of participants preferred CTC, 27.4% reported no preference, and 24.9% preferred OC (p<0.001). Repeat screening with CTC is currently recommended every 5 years and with OC every 10 years. 80.5% of the participants were willing to be screened again with CTC in 5 years and 97.5 % were willing to be screened again with OC in 10 years (p<0.001). If the screening interval for CTC were extended to ten years, 93.7% of participants were willing to return for screening (p<0.001). If BP were unnecessary, 91.0% were willing to be rescreened with CTC in 5 years and 97.5% were willing to be rescreened with OC in 10 years (p<0.001). Conclusions: NCTCT participants preferred CTC to OC, but their willingness to undergo repeat CTC was limited by the shorter interval between screenings currently recommended for CTC as opposed to OC. Improvements in technology that would eliminate the need for bowel preparation or extend the recommended screening interval would likely improve adherence to recommended repeat screening.
