Prognostic significance of lactate dehydrogenase in cabazitaxel chemotherapy for castration-resistant prostate cancer: a multi-institutional study

Prognostic significance of lactate dehydrogenase in cabazitaxel chemotherapy for castration-resistant prostate cancer: a multi-institutional study: Objective

This multi-institutional study aimed to identify prognostic factors for cabazitaxel treatment of castration-resistant prostate cancer (CRPC).

Methods

This study included 74 Japanese patients with CRPC who were treated with cabazitaxel between 2014 and 2017. Associations between clinicopathological factors including serum markers and progression-free survival (PFS) and overall survival (OS) were investigated.

Results

On multivariate analysis, high Gleason score [≥9 vs. ≤7; hazard ratio (HR), 95% confidence interval (CI): 2.00 (1.01–4.34); P = 0.047], presence of pain [HR, 95% CI: 2.02 (1.14–3.58); P = 0.016], and lactate dehydrogenase (LDH) level [HR, 95% CI: 47.31 (3.79–577.49); P = 0.0019] were significantly associated with PFS. Similarly, number of docetaxel cycles [HR, 95% CI: 0.050 (0.0037–0.45); P = 0.0057], performance status [≥2 vs. 0; HR, 95% CI: 5.07 (1.57–16.24); P
