Özet
OBJECTIVE: We present our data comparing retrospectively the efficacy of abiraterone and cabazitaxel in patients who progress after docetaxel treatment. PATIENTS AND METHODS: The study included 56 patients diagnosed with hormone-refractory metastatic prostate cancer who were previously treated with abiraterone therapy at four oncology centers in Turkey. RESULTS: With abiraterone, the patients had a median progression-free survival (PFS) of 5.9 months (95% confidence interval (CI) for hazard ratio (HR) (4.4-7.4)) and an overall survival of 13.4 months (95% CI for HR (5.5-21.3)). When we compared the disease-free survival (DFS) of reference patients treated with cabazitaxel as a second-line treatment with those receiving second-line abiraterone therapy, there was no significant difference. (PFS = 5.9 months with cabazitaxel vs. 6.7 months with abiraterone, P = 0.213). CONCLUSION: This study has shown that in our experience abiraterone acetate is an effective agent in metastatic castration-resistant prostate cancer (mCRPC) regardless of the line of treatment.
