Abstract

This study explores variation in stage-specific survival in women diagnosed with breast cancer in transitioning countries. We obtained data of women diagnosed between 2008 and 2012 from 11 population-based cancer registries (PBCRs) in 10 countries, with follow-up until December 2014. Following stage data standardization and multiple imputation for missing data, we estimated age-standardized 1-, 3-, and 5-year net survival (ASNS) by stage and age group. Stage distribution varied significantly across jurisdictions. Puerto Rico had over 4 in 5 patients diagnosed with early stage (stage I/II), while India, Trivandrum, and Thailand, Khon Kaen had
