摘要: Abstract Objective We described the role of patient-related and clinical factors on age disparities in colon cancer survival among patients aged 50-99 using New Zealand population-based registry data linked to hospitalization data. Design included new cases diagnosed between 1 January 2006 31 July 2017, followed up December 2019. these hospitalisation for five years before diagnosis. modelled effect at diagnosis, sex, deprivation, comorbidity, route diagnosis by stage (localized, regional, distant, missing). Results Net decreased as increased, notably advanced stages missing stage. The excess mortality older was minimal localised cancers, maximal during first six months regional 18 distant over three stages. pattern hazard varied according sex comorbidity with Conclusion present study shows that reflecting timeliness most affected difference middle-aged patients, probably impacting treatment strategy. Because high risk poor outcomes related efforts made improve earlier are likely help reduce Zealand.
