Abstract

Purpose

We determine the progression and survival rates in patients with locally advanced prostate cancer treated with radical prostatectomy without adjuvant treatment, and investigate subgroups of patients who may not benefit from this treatment.

Materials and Methods

Radical prostatectomy was performed in 83 patients with T3 prostate cancer. The patients were divided in subgroups with T3G1 to 2 and T3G3 tumors, which were evaluated for clinical progression, local recurrence, distant metastases, biochemical progression, and overall and cancer specific survival at 5 and 10 years by Kaplan-Meier curves. The results were compared to those of 190 patients with locally confined tumors.

Results

At 5 and 10 years overall survival was 75 and 60%, and cancer specific survival was 85 and 72%, respectively. At 5 and 10 years clinical progression was 41 and 69%, local recurrence 18 and 44%, and distant metastases 31 and 50%, respectively. Biochemical progression at 5 years was 71%. Patients with poorly differentiated tumors showed significantly lower survival and higher progression rates compared to those with well or moderately differentiated tumors. Progression and survival in patients with T3G1-2 tumor were not significantly different from those for patients with locally confined tumors.

Conclusions

Radical prostatectomy as monotherapy in patients with locally advanced non-metastatic prostate cancer (T3) produces acceptable results in those with well or moderately differentiated tumors. The results of progression and survival are not significantly different from those in patients with locally confined prostate cancer. However, patients with poorly differentiated tumors (T3G3) have early progression and need adjuvant treatment following surgery.
