Background/Aim: Limited information is available to help physicians decide when to introduce cabazitaxel for metastatic castration-resistant prostate cancer (mCRPC) patients. The objective of this study was to assess the optimal timing of cabazitaxel introduction. Patients and Methods: The clinical outcomes of 66 mCRPC patients receiving cabazitaxel following failure of docetaxel were retrospectively analyzed. Results: Among the parameters possibly affecting the timing of cabazitaxel introduction, only an increased prostate-specific antigen (PSA) value from the diagnosis of CRPC had a significant impact on overall survival (OS) after the introduction of cabazitaxel. Furthermore, there was a significant correlation between the increased PSA value from the diagnosis of CRPC and the baseline PSA value at cabazitaxel introduction. Multivariate analysis showed that only the baseline PSA value at cabazitaxel introduction is an independent predictor of OS. Conclusion: A comparatively low PSA value could be an alternative index suggesting the optimal timing for cabazitaxel introduction.
