Concordance of National Cancer Registration with self-reported breast, bowel and lung cancer in England and Wales: a prospective cohort study within the UK Collaborative Trial of Ovarian Cancer Screening
Menée au Royaume-Uni dans le cadre d'un essai de dépistage du cancer de l'ovaire entre 1995 et 2007, cette étude de cohorte prospective analyse la concordance entre les données issues des registres anglais et gallois des cancers avec les données fournies par les patientes sur leur cancer du sein, de l'intestin ou du poumon
Background: It has been suggested that lower UK cancer survival may be due to incomplete case ascertainment by cancer registries.
Methods: We assessed concordance between self-reported breast, bowel and lung cancer and cancer registration (CR) for 1995–2007 in England and Wales in the UK Collaborative Trial of Ovarian Cancer Screening.
Results: Concordance of breast cancer CR was higher (94.7%:95% CI: 94.1–95.3%) than for bowel (85.1%:95% CI: 82.1–87.8%) and lung (85.4%:95% CI: 76.3–92.0%). CR concordance was lower in breast cancer (94.5% vs 98.8%) survivors compared with deceased but the difference was small. No difference was found for bowel (85.3% vs 94.6%) or lung (87.1% vs 90.5%) cancer.
Conclusion: Concordance of CR and self-reported cancer is high. Incomplete registration is unlikely to be a major cause of lower UK survival rates.
