Long-Term Breast Cancer Outcomes In Canada With Special Analyses Of Cancer Care Access And Mortality Reduction

1601 Background: The objective of this study is to compare main Breast Cancer outcomes in two regions of Canada with different access to Provincial Guideline-based cancer care [GCC]. Since the 1960u0027s, British Columbia has had a centralized provincially funded Cancer program, coordinating GCC care. Adjuvant therapies started in late 1970u0027s; and of screening mammography in late 1980u0027s. Both Programs were implemented province-wide, and at least a decade earlier than in Atlantic Provinces (Atl. Prov.). Both regions have had comparable BrCa registry since 1970. Methods: From 1970-2007 datawere obtained in collaboration with Public Health Agency of Canada and Canadian Cancer Registry database at Statistics Canada. Estimates for annual age standardized rates /100,000 [with Canada 1991 as population reference] were evaluated for BrCa in-situ [ASR-IS]; incidence of invasive BrCa [ASIRs]; and BrCa-specific mortality [ASMRs]. Results were averaged q 10 years. ASMRs were also expressed [in percent] relative to baseli...
