Résumé

We compared disease characteristics, therapies offered and received, and outcomes between older (>75 years) and younger (60-75 years) women with breast cancer (BC) from a regional database in Ontario, Canada. BC surgical cases from 12 hospitals were included. Younger (60-75 years) and older (>75 years) groups were compared. Cox proportional hazards regression with competing risk analyses assessed the relationship between predictor variables, 10-year recurrence and BC-specific mortality. Our sample comprised 774 women; 33.5% were older. Older women had larger tumours, were more likely to have positive nodes, had more comorbidities, were more likely to undergo mastectomy, had less nodal surgery, were less likely to receive adjuvant therapies, and experienced more recurrences and BC-specific deaths (p < 0.05). Significant predictors of recurrence were older age, higher grade and disease stage, and omission of nodal surgery. Older age, higher grade, and stage were predictors of BC-specific mortality. Older BC patients (>75 years) received less treatment and experienced increased recurrence and BC-specific mortality.

BACKGROUND BACKGROUND
We compared disease characteristics, therapies offered and received, and outcomes between older (>75 years) and younger (60-75 years) women with breast cancer (BC) from a regional database in Ontario, Canada.
METHODS METHODS
BC surgical cases from 12 hospitals were included. Younger (60-75 years) and older (>75 years) groups were compared. Cox proportional hazards regression with competing risk analyses assessed the relationship between predictor variables, 10-year recurrence and BC-specific mortality.
RESULTS RESULTS
Our sample comprised 774 women; 33.5% were older. Older women had larger tumours, were more likely to have positive nodes, had more comorbidities, were more likely to undergo mastectomy, had less nodal surgery, were less likely to receive adjuvant therapies, and experienced more recurrences and BC-specific deaths (p < 0.05). Significant predictors of recurrence were older age, higher grade and disease stage, and omission of nodal surgery. Older age, higher grade, and stage were predictors of BC-specific mortality.
CONCLUSION CONCLUSIONS
Older BC patients (>75 years) received less treatment and experienced increased recurrence and BC-specific mortality.
