5 HDR - Brachytherapy bned dependent on risk group classification (D Amico) Deger S et al, Eur Urol 2005; 47: 441

6 Definition of Relapse PSA in 3 consecutive measures 2 weeks apart PSA of 2 ng/ml above Nadir after radiation therapy BUT not every PSA-relapse is a clinical relapse

7 PSA Progression after Radiation Locoregional relapse versus systemic relapse

8 Diagnosis of Local Relapse Pre-Radiation Parameters ct - stage < T3b, N0 PSA <10 ng/ml Gleason Score < 3+4 Posttherapeutic Parameters late PSA - relapse (>1-2 years after radiation) slow PSA (PSADT >10-12 months) Grossfeld et al. Urology 2002; 60 (suppl 3A); 57

9 Verification of Local Relapse Histological verification is mandatory for treatment PCA detection and Ki-67 positivity Biopsy only after PSA Bounce!!

11 PET/CT & Local Relapse n = 45 with histologically confirmed local relapse n = 45 with preoperative 11 C-PET/CT local detection rate Correlation Biopsy and 11 C-PET/CT 100% Correlation RPE and 11 C-PET/CT 90% Cancer Foci Total Histology PET/CT Heidenreich A et al., AUA/EAU 2007

13 Treatment of Local Relapse no EBM level 1 or 2 trials all recommendations are based on case studies 90% of treatments after radiation are secondary hormonal treatments (SEER data) Grossfeld et al. Urology 2002; 60(suppl 3A): 57

14 Androgendeprivation n = 124 with local relapse after EBRT immediate versus delayed ADT with LHRH cancer-specific survival 70 and 87 months palliative TUR-P 60% percutaneous nephrostomy 30% suprapubic catheter 40% Schellhammer PF et al., 1993

15 Treatment of Local Relapse Salvage - Prostatectomy Salvage Cystoprostatectomy Bladder neck infiltration, compliance, bladder fibrosis Cryotherapy Seeds MRI guided focal therapy

16 Natural History of PSA Relapse PSA, PSADT > 12 months and histologically verified relapse 5-years metastases-free survival of 92% Pinover et al. Cancer 2003; 97: 1127 Routine Biopsy 2 years after Radiatio 16% Progression after 5 years if Bx - 40% Progression after 5 years if Bx + Pollack et al. Int J Radiat Oncol Biol Phys 2002; 54: 677

17 Radical Salvage Prostatectomy DOGMA Dogma 1: Dogma 2: radical prostatectomy after radiation therapy is not possible if radical prostatectomy will be performed after radiation therapy, significant complications will occur

18 Radical Salvage Prostatectomy Indication (n = 98, ) histologically verified prostate cancer negative CT scan and skeletal scintigraphy PSADT > 12 months PSA 15ng/ml bladder capacity 300ml, competent sphincter, no bladder neck invasion Heidenreich A et al., Eur Urol 2009
