Female breast cancer management and survival: The experience of major public hospitals in South Australia over 3 decades-trends by age and in the elderly.

Breast-cancer survival increases applied to all ages, including 80+ years, but poorer outcomes persisted in this older group and the gap did not reduce. A key question is whether the best trade-off now exists between optimally therapeutic cancer treatment and accommodations for frailty and co-morbidity in the aged, or whether opportunities exist for better trade-offs and better survival. Local registry data are important for describing local service activity and outcomes by age for local service providers, health administrations and consumer groups; monitoring disparities; and indicating effects of local initiatives.
