Cabazitaxel in Metastatic Castration-Resistant Prostate Cancer Patients Progressing after Docetaxel: A Prospective Single-Center Study

subject

description

<b><i>Purpose:</i></b> 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. <b><i>Methods:</i></b> 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/m<sup>2</sup> every 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. <b><i>Results:</i></b> 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 (β = 0.377, <i>p</i> < 0.01). <b><i>Conclusions:</i></b> 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.
