Abstract
Standard treatments for patients with stage I-III breast cancers include 1) breast conserving surgery (BCS) plus adjuvant radiotherapy; 2) mastectomy; and 3) BCS alone (e.g. age > 70 in stage I for ER/PR+ status and received hormone therapy). Currently, there is a lack of information regarding frequency and variation in utilization of these treatments in Alberta and information regarding the survival outcomes achieved in the general population by treatment type and stage. In this study, we found that rural patients were less likely to receive BCS. Stage I-III patients who received BCS plus adjuvant radiotherapy had a lower hazard of overall death and stage II or III patients had a lower hazard of breast-cancer-specific death than those who received mastectomy; additionally, stage I and II patients who received BCS alone had a higher hazard of overall and breast-cancer-specific death. These suggested an inequity of care among Alberta breast cancer patients.
