BackgroundAfter experiencing a distant recurrence, breast cancer patients have a poor prognosis; fewer than 5% survive for ten or more years. However, the time to death is highly variable, ranging from a few months to many years. The purpose of this study is to identify, in a large hospital-based series of patients with early-stage breast cancer, factors which predict survival after distant recurrence.MethodsWe studied a cohort of 2312 women diagnosed with invasive breast cancer at Women's College Hospital between 1987 and 2000 (stages I-III). For each patient, we abstracted information on age at diagnosis, the initial presentation of the cancer (tumour size, lymph node status, tumour grade, ER status, PR status, HER2 status), treatment (surgery, radiotherapy, chemotherapy, hormone therapy), the dates of all tumour recurrences (local, regional, distant) and the dates and causes of death. The Cox proportional hazards model was used to estimate the univariate and multivariate hazard ratios for death from breast cancer following distant recurrence associated with the various tumour features.ResultsAfter a mean follow-up of 12.8years from diagnosis, 523 distant recurrences were recorded among women in the cohort (23% of 2312) and 604 women (26%) died of breast cancer. For the 484 women who had a distant recurrence on record and died of breast cancer, the mean time from distant recurrence to death was 2.0years (range 0-11.9years). In a multivariate analysis, only two factors were significantly associated with time to death after distant recurrence: ER status (positive vs. negative, HR 0.56; 95% CI 0.43-0.71; p
