AI Summary
This article discusses the validity and timeliness of cancer diagnosis data collected during a prospective cohort study and reported by the English and Welsh cancer registries. The study found similar completeness of data fields, concordance, and timeliness between on-site and centrally collected cancer outcomes data. The findings indicate that central registry data can aid in alleviating the resource burden in clinical trials and improving cancer research. However, additional resources may be necessary for cancer registries to provide data for registry-based trials on a larger scale.
We report similar completeness of data fields, concordance, and timeliness between on-site and centrally collected cancer outcomes data. Our findings suggest that central registry data can help alleviate the resource burden in clinical trials and improve cancer research. Cancer registries might need additional resources to provide data for registry-based trials at scale.
