[Clinical outcome of radical prostatectomy for stage C prostate cancer: comparison with other treatment modalities].
Of the 69 patients with clinical stage C prostate cancer under 75 years old and with good performance status between 1986 and 1995, 29 underwent radical prostatectomy combined with endocrine therapy, 21 underwent radiation therapy combined with endocrine therapy and remaining 19 patients were treated by endocrine therapy alone. The median followup was 44 months (range 4 to 122). Radical prostatectomy resulted in progression-free rates of 79% and 61% at 5 and 10 years, respectively. Progression-free rates were lower in patients with lymph node metastasis or positive surgical margins. In patients with clinical stage T3a-c and well or moderately differentiated tumor, radical prostatectomy resulted in a progression-free rate of 100% at 5 years. However, in patients with clinical stage T4a or poorly differentiated tumor, radiation therapy resulted in a better progression-free rate than radical prostatectomy. These findings suggest that patients with clinical stage T3a-c and well or moderately differentiated tumor will benefit from radical prostatectomy combined with endocrine therapy and that radiation therapy well be effective for advanced diseases.
