COVID-19; COLORECTAL CANCER SCREENING
The study assessed the impact of delayed invitation on screen-detected and interval colorectal cancers (CRC) in a FIT-based CRC screening program. Individual-level data from individuals who participated in 2017 and 2018 with a negative FIT and were eligible for screening in 2019 and 2020 were analyzed. The results showed that the first COVID-19 wave had a modest impact on screening yield, and a small proportion of FIT negatives had interval CRC, possibly due to an extended invitation interval.
ObjectiveTo assess the impact of delayed invitation on screen-detected and interval colorectal cancers (CRC) within a faecal immunochemical testing (FIT)-based CRC screening programme. DesignAll individuals that participated in 2017 and 2018 with a negative FIT and were eligible for CRC screening in 2019 and 2020 were included using individual-level data. Multivariable logistic regression analyses were used to assess the association between either the different time periods (ie, 'before', 'during' and 'after' the first COVID-19 wave) or the invitation interval on screen-detected and interval CRCs. ResultsPositive predictive value for advanced neoplasia (AN) was slightly lower during (OR=0.83) and after (OR=0.92) the first COVID-19 wave, but no significant difference was observed for the different invitation intervals. Out of all individuals that previously tested negative, 84 (0.004%) had an interval CRC beyond the 24 months since their last invitation. The time period of invitation as well as the extended invitation interval was not associated with detection rates for AN and interval CRC rate. ConclusionThe impact of the first COVID-19 wave on screening yield was modest. A very small proportion of the FIT negatives had an interval CRC possibly due to an extended interval, which potentially could have been prevented if they had received the invitation earlier. Nonetheless, no increase in interval CRC rate was observed, indicating that an extended invitation interval up to 30 months had no negative impact on the performance of the CRC screening programme and a modest extension of the invitation interval seems an appropriate intervention.
