METHODS: Nineteen patients underwent RP after biopsy-proven PCa post-focal VTP. We reported: operation time, blood loss, transfusion, complications, urethral catheterization time, functional outcomes, and short-term oncologic outcomes.
RESULTS: Median age was 64 years (58-70). Median PSA before VTP was 6.30 ng/ml (3.20-9.80). Median delay between VTP and RP was 17 months (8-48). Median blood loss was 400 ml (100-1,000). Median operation time was 150 min (90-210), median urethral catheterization time was 7 days (5-18), and median hospital stay was 7 days (4-21). There was no perioperative mortality. Three patients had related per-operative complications: one pelvic hematoma (150 cc) (Clavien IIIa), one per-operative transfusion (900 cc hemorrhage) (Clavien II), and one superficial wound infection (Clavien I). After a median follow-up of 10 months (1-46), 13 were completely continent (68 %), five needed ≤ 1 pad/day, and one needed 3 pads/day (Clavien I). Severe erectile dysfunction was observed before and after RP (respectively 8 and 18). Ten patients regained potency with appropriate treatment. Median postoperative PSA was 0.02 ng/ml (< 0.01-0.38) and remained undetectable for 16 patients (84 %). Nine patients had positive margins and six underwent complementary radiotherapy. Positive margins were significantly associated with bilateral VTP [risk ratio = 4.3, 95 % confidence interval (1.6-11.7), p = 0.003].
CONCLUSION: Salvage RP after VTP treatment was feasible, safe, and efficient to treat most of the locally recurrent PCa. Short-term oncologic and functional outcomes were promising, but further studies are required.
