Five-year cancer survival by stage at diagnosis in Canada

Cancer survival estimates provide insights into the effectiveness of early detection and treatment. The stage of cancer at diagnosis is an important determinant of survival, reflecting the extent and spread at the time of disease detection. The recent extension of the Canadian Cancer Registry death-linked analytic file from 2014 to 2017 now offers an opportunity to provide more up-to-date net survival (NS) figures and to profile, for the first time, five-year NS estimates for Canada (excluding Quebec). This study presents five-year stage-specific cancer and five-year NS estimates for the most commonly diagnosed cancers in Canada.
