Temporal trends in the incidence and relative survival of XXXX in Canada: A population-based study.

@entity1 @entity1149 @entity2
OBJECTIVES: The objective of this study was to estimate trends in incidence and relative survival ratio in @entity1 diagnosed with @entity2 in Canada over the period of 1992-2007. MATERIALS AND METHODS: We identified @entity1 with primary invasive @entity1149 in the Canadian Cancer Registry (CCR) dataset. @entity1 younger than 18 years of age were excluded in this analysis. A flexible parametric model was used to estimate one- and five-year relative survival ratios and excess mortality rate. RESULTS: In total 182,417, @entity1 from CCR dataset with @entity2 were identified of which 57.2% (n=106,197) were male and the mean age at diagnosis was 68.8 (SD=11.0) years. The incidence rate of @entity2 decreased in @entity1 and increased in @entity1 . Although one-year relative survival ratio slightly improved over time for both genders and most age groups, five-year relative survival decreased for most of the groups. CONCLUSIONS: Although the incidence rate of @entity2 continued to decrease in @entity1 , it is increasing in @entity1 and the gap in incidence between @entity1 and @entity1 is narrowing. The one-year relative survival ratio gradually increased for most age groups over the study period, particularly for the younger age groups. Additionally, excess mortality rate is at its peak shortly after diagnosis and for the first 6 months and thereafter gradually decreases.
