Long-term outcomes after breast conservation therapy for early stage breast cancer in a community setting.

We, as a large community practice, retrospectively reviewed our experience in treating early stage breast cancer to determine rates of breast-conserving therapy (BCT), disease outcomes after such treatment, and risk factors for local recurrence. A hospital tumor registry was used to identify breast cancer cases diagnosed between 1987 and 2003. Rates of BCT and radiotherapy were examined using primary treatment data.
