Prostate cancer (PCa) patients with lymph node recurrence after radical prostatectomy (RP) are usually managed with androgen-deprivation therapy. Despite the absence of prospective randomized studies, salvage lymph node dissection (LND) has been proposed as an alternative treatment option. To examine long-term outcomes of salvage LND in patients with nodal recurrent PCa documented by 11C-choline positron emission tomography/computed tomography (PET/CT) scan. Overall, 59 patients affected by biochemical recurrence (BCR) with 11C-choline PET/CT scan with pathologic activity treated between 2002 and 2008 were included. Pelvic and/or retroperitoneal salvage LND. Biochemical response (BR) was defined as prostate-specific antigen (PSA) 0.2 ng/ml. Clinical recurrence (CR) was defined as a positive PET/CT scan after salvage LND in the presence of a rising PSA. Kaplan-Meier curves assessed time to BCR, CR, and cancer-specific mortality (CSM). Cox regression analyses were fitted to assess predictors of CR. Median follow-up after salvage LND was 81.1 mo. Overall, 35 patients (59.3%) achieved BR. The 8-yr BCR-free survival rate in patients with complete BR was 23%. Overall, the 8-yr CR- and CSM-free survival rates were 38% and 81%, respectively. In multivariable analyses evaluating preoperative variables, PSA at salvage LND represented the only predictor of CR (p=0.03). When postoperative variables were considered, BR and the presence of retroperitoneal lymph node metastases were significantly associated with the risk of CR (all p ≤ 0.04). Our study is limited by the lack of a control group. Salvage LND may represent a therapeutic option for patients with BCR after RP and nodal pathologic uptake at 11C-choline PET/CT scan. Although most patients progressed to BCR after salvage LND, roughly 40% of them experienced CR-free survival. Salvage lymph node dissection may represent a therapeutic option for selected patients with nodal recurrence after radical prostatectomy. Roughly 40% of men did not show any further clinical recurrence at long-term follow-up after surgery.

Purpose: Candidates for definitive therapy for localized prostate cancer (PCa) should have life expectancy (LE) in excess of 10 years. However, LE estimation is difficult. To circumvent this problem, we developed a nomogram predicting 10-year LE for patients treated with either radical prostatectomy (RP) or external-beam radiation therapy (EBRT) and compared it with an existing tool. Patients and Methods: Between 1989 and 2000, 9,131 men were treated with either RP (n = 5,955) or EBRT (n = 3,176), without any secondary therapy and all deaths were considered unrelated to PCa. Age and Charlson comorbidity index (CCI) predicted 10-year LE in Cox regression models. We used 200 bootstrap resamples to internally validate the nomogram. Results: Median age was 66 years, median CCI was 1, median follow-up was 5.9 years and median actuarial survival was 13.8 years. Advanced age (P < .001), elevated CCI score (P < .001) and treatment type (EBRT v RP, P < .001) were independent predictors of poor 10 year LE. The nomogram predicting 10 year LE after either RP or EBRT was 84.3% accurate in split sample validation and was 2.9% (P = .007) more accurate than the existing tool. A cutoff of 70% or less was 84% accurate in identifying men who did not survive beyond 10 years. Conclusion: Our nomogram can accurately identify those individuals who do not have sufficient LE to warrant definitive PCa treatment and can help optimizing therapy decision-making.
