Abstract

Objective: Evaluation of outcomes with Docetaxel in patients with metastatic castration-resistant prostate cancer after first-line failure of Abiraterone acetate. Patients and methods: A cross-sectional descriptive study on 40 patients with metastatic castration-resistant prostate cancer after first-line failure of Abiraterone acetate in Vietnam National Cancer Hospital from January 2014 through May 2023. Kaplan-Meier curves were used to estimate the time to treatment failure Results: The mean age of the patients was 71,5 (± 7,6), median PSA pretreatment was 88,9 ng/ml (IQR: 14,4-137,8). The median number of Docetaxel cycles was 5 cycles (1-10). The rate of patients achieving PSA decline ≥ 30% was 50% and PSA response was 27,5%. The median time to treatment failure with Docetaxel was 4,9 months (95% CI: 1,2-8,6). Time to treatment failure with Abiraterone <12 months, Docetaxel cycles < 6, and PSA decline < 30% are factors that have a significantly lower time to treatment failure with Docetaxel (p < 0,001). Conclusion: The rate of patients who achieved PSA response was 27,5%, and the median time to treatment failure with Docetaxel was 4,9 months (95% CI: 1,2-8,6).
