Purpose: The present study aims to evaluate the efficacy of cabazitaxel in combination with prednisone treatment in Italian patients affected by hormone-refractory metastatic castration-resistant prostate cancer (mCRPC) previously treated with docetaxel plus prednisone. Methods: Thirty patients with mCRPC were enrolled between June 2013 and January 2016 (the last follow-up was in January 2016). Cabazitaxel was used according to the summary of product characteristics and administered at a dose of 25 mg/m2every 3 weeks plus oral prednisone at a dose of 5-mg tablets twice a day continuously. The reduction in serum prostate-specific antigen (PSA) was the primary endpoint while reducing pain, safety, progression-free survival, response rate and overall survival (OS) were secondary endpoints. Results: Cabazitaxel was well tolerated, showing a manageable toxicity profile, associated with a modest objective response rate and a good reduction in PSA levels. Only 12 patients (40%) had a partial response, 10 patients (33%) showed stabilization of disease and 8 (27%) experienced disease progression. The median OS was 14.8 months (95% CI: 11.6-19.8). The linear regression analysis revealed that PSA response was an important predictor of OS, showing a positive correlation with OS (Î² = 0.377, p < 0.01). Conclusions: Three-week treatment with cabazitaxel was found to be valid and was a well-tolerated treatment option for patients with mCRPC after a first-line docetaxel treatment.
