[Enzalutamide and Abiraterone in the Treatment of Metastatic Castration-resistant Prostate Cancer after Chemotherapy]
Aim:
Enzalutamide and abiraterone represent new therapeutical options in the treatment of metastatic castration-resistant prostate cancer (mCRPC). The aim of the presented study was retrospective analysis of clinical experience and efficacy of enzalutamide or abiraterone in the postchemo indication in patients with mCRPC.
Patients And Methods:
A total of 32 mCRPC patients were evaluated. All patients received one or more lines of chemotherapy. Twenty-three patients were treated by enzalutamide, nine patients were treated by abiraterone. We defined two parameters: over all survival and progression-free survival.
Results:
The median follow-up was 6.5 months. A total of 10 patients treated by enzalutamide progressed (43.47%) and eight patients died (34.78%). A total of five patients treated by abiraterone progressed (55.56%) and one patient died (11.11%). We did not observe any statistical difference in over all survival (HR 0.2362, 95% CI 0.0295- 1.8942; p = 0.102) and in progression-free survival (HR 0.9853, 95% CI 0.2934- 3.308; p = 0.939) between enzalutamide and abirateron.
Conclusion:
Our retrospective study demonstrated similar efficacy of enzalutamide and abiraterone in mCRPC patients previously treated by chemotherapy.
