Abstract

Objective To report the long-term outcome of high-grade prostate cancer treated with radical prostatectomy (RP) as initial monotherapy, analyse the effect of clinical and pathological variables on survival, and report cancer-related symptoms. Patients and Methods A retrospective chart review was conducted to identify patients with Gleason 8-10 prostate cancer found on pathological review in men undergoing RP as initial therapy for clinically localized disease between 1988 and 2005. Kaplan-Meier analysis was used to calculate event-free survival. Univariable and multivariable analyses were used to assess the effects of clinical and pathological variables on prostate-specific antigen (PSA) recurrence. Results After excluding 20 patients, 119 were identified with pathologically confirmed high-grade cancers at the time of RP. The overall median (interquartile range) follow-up was 73 (41-113) months. Twenty-four (20%) patients had organ-confined cancer, 60 (50%) had specimen-confined cancer, and 14 (12%) had nodal metastasis. Kaplan-Meier analysis showed overall survival rates at 5 and 10 years, respectively, of 90% and 75%, cancer-specific survival of 92% and 82%, and a PSA recurrence-free follow-up at 5 years of 31%. Using univariable analysis, preoperative PSA level, pathological Gleason score, pathological stage, surgical margin status and tumour volume were found to significantly affect the PSA recurrence-free follow-up. No variables were significant on multivariable analysis. Cancer-related symptoms were reported by only 14 patients, with a median time from surgery to first symptom of 43 months. Conclusion High-grade prostate cancer can be treated with RP as initial monotherapy with an acceptable 10-year cancer-specific survival (82%). The PSA recurrence-free follow-up is poor (31% at 5 years). However, few patients progress to symptomatic recurrence after PSA relapse within the first 5 years.
