Sumario: | OBJECTIVE: The aim of this study was to evaluate the biochemical recurrence (BCR) in patients with high-risk prostate cancer (PCa) treated with radical prostatectomy (RP) or radiotherapy (RT) plus androgen deprivation therapy (ADT). METHODS: Subjects were patients with National Comprehensive Cancer Network-defined high-risk PCa treated with either RP or RT plus ADT. We calculated BCR-free survival in patients with those treatments and evaluated risk factor against BCR. RESULTS: A total of 114 patients, 71 RP and 43 RT plus ADT, were evaluated. A total of 59 and 20.9% of patients experienced BCR in the RP and RT treatment groups, respectively. The 5-year BCR-free survival probabilities improved significantly for patients who received RT compared to those who received RP (81.3 vs 37.3%, P<0.001). According to the number of risk factors, 59.2% of patients in the RP and 51.2% of patients in the RT treatment groups were classified with one risk factor (P<0.014). The 5-year BCR-free survival probabilities for patients treated with RP were 46.6 and 21.7% for one and multiple risk factors, respectively (P=0.008). On univariate analysis, only the number of risk factors had a significant impact on the risk of BCR. Meanwhile, there were no significant differences in the 5-year BCR-free survival probabilities between one and multiple risk factors in patients treated with RT. CONCLUSION: Among patients treated with RP, a marked heterogeneity existed in the oncological outcomes. Based on these findings, the number of risk factors should be emphasized to decide the optimal treatments for patients with high-risk PCa. |
