Abstract

INTRODUCTION: Previous studies have shown that primary breast cancer patients with estrogen receptor (ER)-positive status have better outcomes in terms of both overall survival and disease-free intervals (DFI). However, 25.2 % of our ER-positive patients experienced recurrence. This study aimed to define factors potentially predicting survival after first recurrence in surgically treated patients with stage I-III breast cancer. METHODS: We retrospectively analyzed 252 females with recurrent breast cancer who had undergone surgery and been followed at Kyoto University Hospital in Japan. Age, clinical stage, pathological stage, axillary lymph node involvement, ER status at the time of diagnosis, progesterone receptor status, human epidermal growth factor receptor 2 status, operative method, adjuvant chemotherapy, adjuvant endocrine therapy, use of trastuzumab after recurrence, site of recurrence, DFI, and time of recurrence were examined for possible influences on survival after the first recurrence. RESULTS: Positive ER status and positive PR status at the time of diagnosis were significantly favorable factors of survival after first recurrence for patients with recurrence, p < 0.001 and p = 0.021, respectively. More than two sites of recurrence (p < 0.001) were associated with shorter survival time after the first recurrence on multivariate analysis. Survival of patients with recurrent breast cancer steadily improved from 1980-1994 to 1995-2008, significantly in ER-negative subgroups. CONCLUSIONS: Positive ER status at the time of diagnosis is a powerful predictor for favorable survival after first recurrence. Survival time after first recurrence of breast cancer has steadily increased in recent decades. Advances in treatments and attitudes about breast cancer have contributed to this improvement in survival after first recurrence.
