Background: To assess the role of chemotherapy in metastatic, hormone-naïve prostate cancer, we presents the preliminary data of a pooled analysis comparing the outcome of patients with metastatic hormone-naïve prostate cancer. Methods: A pooled analysis of the outcome of randomized clinical trials approaching the role of docetaxel in metastatic hormone-naïve prostate cancer was performed using a random effect model. The final outcome of all the patients enrolled into the trials was the primary end point of our analysis. The pooled final result was reported as pooled Hazard Ratio and 95% Confidence Interval. The between-the trials heterogeneity was assessed using the I2 test. An α-error of 5% was identified as index of statistical significance. Overall survival of the entire population enrolled into the trials was the outcome of the preliminary analysis, while no subgroup analysis was performed in this preliminary phase of a multi-steps analysis. Results: Three trials (the CHAARTED, the STAMPEDE and the GETUG-AFU 15 trial) were considered eligible and included into the analysis. A pooled Hazard Ratio of 0.76 (95% Confidence Interval of 0.59-0.98, p = 0.037) was detected for overall survival, with an I2 of 67.8. The pooled datum was obtained observed the outcome of 951 patients treated with docetaxel plus androgen blockade and 1338 with androgen blockade alone. Conclusions: Although the between-the-trials heterogeneity seems to suggest caution in the final interpretation of the results, a significant reduction of the risk of death can be obtained with docetaxel in the treatment of metastatic hormone-naïve prostate cancer. Our preliminary analysis, including all the patients with metastatic hormone-naïve prostate cancer, seems to suggest a role of docetaxel in all the patients with metastatic disease; further data are probably needed to detect its role in some different subclasses of patients (patients with high burden of the disease, fit or unfit patients, elderly patients).
