We analyzed PSA progression free survival (PFS) after radical prostatectomy and or radiotherapy in accordance to the location of the recurrence and the performed salvage surgery. METHODS: We retrospectively analyzed 274 patients with salvage surgeries. 142, 18, and 114 patients underwent salvage radical prostatectomy (SPRE, Group1), locoregional recurrences mainly in seminal vesical remnants (SVR, Group2) or salvage lymph node dissection (SLND, Group3). All patients were diagnosed either by Choline- or more lately PSMA-PET CT. All surgeries had been done open. In Group1 radical prostatectomy and lymph node dissection, in Group 2 the seminal vesicals and in Group3 an ipsilateral pelvic lymph node dissection had been performed due to imaging results. RESULTS: Median age at time of surgery was 67(62-72)years. Median PSA was 3.1(1.45-5.45)ng/ml. Radiotherapy or hormone therapy before salvage surgery in Group 1,2,3 was done in 100%, 61,1%, 54,39% and 12,6%, 27,8%, 18,42% of the patients. Median progression free survival in Group 1, 2, 3 is 41(11.104), 29 (8-47) and 8 (2-21) months (p<0.001). PSA PFS in Group1/2 and Group 1/3 differed significantly with an HR of 1.85 (95%CI;1,0-3.44) and HR of 2.72 (95%CI; 1,84-4,04). Only age at time of surgery and interval from primary treatment to salvage procedure in months were significant predictors in an univariate Cox regression analysis. CONCLUSIONS: We demonstrate that the best biochemical control in salvage surgeries is achieved in patients with isolated recurrence in the prostate after radiotherapy. The effect of salvage surgery decreases with increasing distance of the site of recurrence to the prostate.
