ABSTRACT
In multivariate analysis, GS of the regular prostatectomy specimen was the only statistically significant parameter for pT2R1 prostate cancer.
ABSTRACT
PURPOSE: To predict biochemical recurrence respecting the natural course of pT2 prostate cancer with positive surgical margin (R1) and no adjuvant/neoadjuvant therapy. METHODS: A multicenter data analysis of 956 patients with pT2R1N0/Nx tumors was performed. Patients underwent radical prostatectomy between 1994 and 2009. No patients received neoadjuvant or adjuvant therapy. All prostate specimens were re-evaluated according to a well-defined protocol. The association of pathological and clinical features, in regard to BCR, was calculated using various statistical tests. RESULTS: With a mean follow-up of 48 months, BCR was found in 25.4 %. In univariate analysis, multiple parameters such as tumor volume, PSA, Gleason at positive margin were significantly associated with BCR. However, in multivariate analysis, Gleason score (GS) of the prostatectomy specimen was the only significant parameter for BCR. Median time to recurrence for GS ≤ 6 was not reached; 5-year BCR-free survival was 82 %; and they were 127 months and 72 % for GS 3+4, 56 months and 54 % for GS 4 + 3, and 27 months and 32 % for GS 8-10. The retrospective approach is a limitation of our study. CONCLUSIONS: Our study provides data on the BCR in pT2R1-PCa without adjuvant/neoadjuvant therapy and thus a rationale for an individual's risk stratification. The data support patients and physicians in estimating the individual risk and timing of BCR and thus serve to personalize the management in pT2R1-PCa.

BACKGROUND: Anastomotic strictures following radical prostatectomy for prostate cancer are reported in about 1-8% of all patients. Endourologic management usually does not result in very high cure rates but is associated with very high rates of recurrences. There is no standard management of these postoperative long-term complications and quite often the patient ends up having a transurethral or suprapubic catheter as a simple long-term solution. RESULTS: Twenty-four patients with recurrent anastomotic strictures and a mean of 3.5 (2-9) previous transurethral surgical interventions were operated between 2004 and 2011. All patients underwent perineal bladder neck closure and a continent vesicostomy with either an appendiceal or an ileal stoma implanted in the bladder. The mean OR time was 125 (100-195) min, and the mean time of hospitalisation was 12.5 (9-27) days. There were no significant intra- or perioperative complications. Three patients developed a significant urinary tract infection, two patients had to be treated for the development of a paralytic ileus and one patient needed to undergo revision surgery for a urethral fistula. After a mean follow-up of 37 (10-78) months, two patients developed a stomal stenosis which was corrected surgically. CONCLUSIONS: Based on our experience, bladder neck closure and continent vesicostomy represent a valuable therapeutic option in the management of recurrent anastomotic strictures following radical prostatectomy.
