Abstract
Purpose
To evaluate the long-term outcomes of patients with prostate cancer who have pathological pT3b N0–Nx, with postoperative PSA < 0.1 ng/ml and no systematic adjuvant treatment.
Materials and methods
Using a monocentric prospectively maintained database, we identified among 2,142 men who underwent minimally invasive radical prostatectomy, 104 pT3b N0–Nx patients, with postoperative PSA < 0.1 ng/ml and at least 5 years of follow-up. Patients were considered for salvage treatment at biochemical recurrence (PSA ≥ 0.2 ng/ml).
Results
The median time of follow-up was 83.5 months (interquartile range [IQR]: 69–99). Overall, 102 patients (98 %) had T2 clinical stage or less. Specimen Gleason score was 7 in 71 patients (68 %) and <7 in 15 (14 %). Thirty-eight patients (37 %) were upgraded for Gleason score after radical prostatectomy. The overall 5-year probability of freedom from biochemical recurrence for the entire cohort was 55.8 % (95 % CI 45.8–65.8) and 73.3 % for patients who had specimen Gleason score <7 (p = 0.005). In univariate analysis, specimen Gleason score and surgical margin status were significant predictors for biochemical failure after radical prostatectomy (p = 0.05 and 0.007, respectively). In multivariate analysis, only specimen Gleason score >7 was significantly associated with biochemical failure (p = 0.009).
Conclusion
SVI is an adverse prognostic factor, but it is not associated with a uniformly poor prognosis. Specimen Gleason score and surgical margin status are significant predictors of recurrence after radical prostatectomy in patients with prostate cancer and SVI.
