AIM: This paper presents a 14-year retrospective study evaluating the survival rates and prognostic factors of breast carcinoma patients treated in private treatment center in the west coast of Turkey. MATERIALS AND METHODS: The survival rates of breast cancer patients (n = 1746) who have been treated from 1995 until 2008 were analyzed. The clinical data include age, menopausal stage, oestrogen (ER) and progesterone (PR) receptor status, and C-erbB-2 status as well as histopathological evaluation. AJCC (2002) was used for clinical tumor staging. Survival rates were computed using standard Kaplan-Meier methods, and the difference in survival curves was analyzed with the log-rank test. RESULTS: The 14-year overall survival, disease-free survival, local failure-free survival, and distant failure-free survival rates were 77%, 95%, 77%, and 94%, respectively. Early-stage patients had higher overall survival rates compared to advanced-stage patients (stage IIIb and IIIc, AJCC 2002), and early-stage patients had higher survival rates than advanced-stage patients for disease-free survival, local failure-free survival, and distant failure-free survival. The risk for cancer development increases significantly for advanced-stage patients with positive ER and PR receptor as well as C-erbB-2 receptor. CONCLUSIONS: The incidence of breast cancer in Turkey is smaller compared to other European countries. Low advanced-stage patient numbers compared to high early-stage patient numbers; and very high median survival times could possibly be the result of the improvement of detection and treatment of breast cancer over the years.
