title: [Cabazitaxel for metastatic castration-resistant prostate cancer progressing after docetaxel treatment: the TROPIC study in France].
abstract: In 2010, results of the TROPIC study demonstrated that, when compared to mitxantrone, the novel taxane cabazitaxel improved median overall survival of patients with metastatic castration-resistant prostate cancer who progressed on or after docetaxel treatment. We report the data on efficacy and toxicity observed in the subgroup of patients included in the French centers. In this phase III randomized international trial, patients received prednisone and were treated with either 25 mg/m(2) cabazitaxel or 12 mg/m(2) mitoxantrone intravenously every three weeks. The primary endpoint was overall survival. The secondary endpoints included progression-free survival (PFS) and safety. Analyses were performed on the intention-to-treat population. Among the 90 patients enrolled in France, the median overall survival was 18 months for the cabazitaxel arm versus 14.3 months for the mitoxantrone arm. An improvement in PFS was also observed, with a median of 1.4 months for the mitoxatrone arm compared to a median of 2.5 months for the cabazitaxel arm. The most common grade ≥ 3 adverse events were hematologic with neutropenia, usually afebrile and digestive with 4 % of patients reporting diarrhea. These results are comparable to those reported for the overall population and the safety profile remains favorable without any toxic death related to cabazitaxel.
