Abstract
Background and aims: Patients with screen-detected colorectal cancer (CRC) have a better stage-specific overall survival than non-screen-detected CRC. Currently, it is unknown if recurrence rates differ between screen-detected and non-screen-detected CRCs, and whether this could explain the observed difference in overall survival. Therefore, we aimed to assess the disease-free survival (DFS) rates in screen-detected and non-screen-detected CRCs and if recurrence affects overall survival.
Methods: Dutch CRC (stage I-III) patients, diagnosed by screening or not in the first 6 months of 2015, were included from the Netherlands Cancer Registry. DFS and survival data were retrieved and analyzed by Kaplan-Meier method. The association between mode of detection and recurrence and overall survival was evaluated with a Cox regression model.
Results: A total of 3725 CRC patients were included, 2073 (55.7%) non-screen detected and 1652 (44.3%) screen detected. Three-year DFS was significantly higher in screen-detected CRC compared with non-screen-detected CRC (87.8% vs 77.2%; P < .001). Stage-specific DFS rates for screen-detected vs non-screen-detected CRC were 94.7% vs 92.3% for stage I (P = .45), 84.3% vs 81.4% for stage II (P = .17), and 77.9% vs 66.7% for stage III (P < .001), respectively. Detection by screening was independently associated with a lower risk of recurrence (hazard ratio, 0.67; 95% confidence interval, 0.55-0.81; P < .001) when adjusted for age, sex, tumor location, stage and treatment. Recurrence independently predicted overall survival (hazard ratio, 15.90; 95% confidence interval, 13.28-19.04; P < .001).
Conclusion: DFS was significantly better in screen-detected compared with non-screen-detected CRCs independent of age, sex, tumor location, stage and treatment, and was associated with an overall survival benefit.
