Background: Elderly patients with metastatic breast cancer have a prognosis and outcome that may be dependent on a host of factors.
Patients And Methods: We retrospectively analyzed 401 female breast cancer patients who developed metastatic disease after the age of 70 years in order to define potential prognostic factors for specific survival at the time of first recurrence.
Results: With a median follow-up of 60 months from the time of recurrence, the median specific survival was 21.
