Introduction: High baseline YKL-40 serum levels are associated with drug resistance in several solid tumours. However, their role in predicting docetaxel (DOC) resistance in prostate cancer (PCa) is unknown. Methods: Pre-treatment serum levels of YKL-40 and prostate-specific antigen (PSA) were analyzed in 109 castration-resistant prostate cancer patients who underwent DOC-therapy. Responsive patients were retreated by repeated series of DOC. Results were compared with the clinical parameters as well as overall (OS) and disease-specific survival (DSS). Results: YKL-40 but not PSA serum levels were significantly higher in patients with baseline resistance to DOC (p = 0.035). Higher YKL-40 and PSA levels were detected in patients with bone metastasis (p = 0.032; p = 0.010) and in those who were not pre-treated with radical prostatectomy (p = 0.011, p = 0.008). High YKL-40 levels were associated with shorter OS (p = 0.037) and DSS (p = 0.017) in patients who received DOC in the first-line setting. In multivariable analysis, ECOG performance status (p = 0.009), presence of any metastases (p = 0.016) and high PSA levels (p = 0.005) remained independent predictors for DSS. Conclusions: YKL-40 may help to identify patients with baseline resistance to DOC and therefore may help to optimize treatment decisions. In accordance, high pre-treatment YKL-40 serum levels were associated with shorter OS and DSS in patients who received DOC as first-line therapy. (C) 2018 S. Karger AG, Basel
