ABSTRACT OBJECTIVE To investigate biochemical recurrence (BCR) rates and data on postoperative incontinence in a large laparoscopic radical prostatectomy (LRP) cohort with extended follow-up. MATERIALS AND METHODS BCR and independent predictors of BCR were identified using Kaplan-Meier and Cox regression analysis of 1845 patients who underwent LRP from 1999 to 2007. Urinary incontinence was evaluated by pads per day and stratified as follows: 0-1 pad: no incontinence; 2-3 pads: mild incontinence; and >= 3 pads: severe incontinence. RESULTS Organ-confined disease, extraprostatic extension, seminal vesicle invasion and lymph node metastasis were present in 71.3%, 20.5%, 6.7% and 3.2% of patients, respectively. The positive surgical margin rate was 29.2%. Postoperatively, 74.9% of the patients were continent, while 9.2% had mild and 15.9% severe incontinence. The mean follow-up was 5 years with a maximum follow-up of 11.3 years. There were 51 overall deaths and six deaths from prostate cancer. The 5-year, 8-year and 10-year BCR-free survival rates were 83.9%, 78.6% and 75.6%, respectively. On univariate analyses preoperative D'Amico risk classification, pathological tumour stage, postoperative Gleason sum and surgical margin status were predictors of BCR (P < 0.001). On multivariable analysis, D'Amico classifi cation, Gleason sum (P < 0.001), postoperative tumour stage (P < 0.001), nodal status (P < 0.001) and surgical margin status (P = 0.002) were independent predictors of BCR. CONCLUSIONS LRP offers excellent long-term functional and oncological results with a low incidence of BCR for patients with localized disease. These results could be used for patient counselling before robot-assisted laparascopic prostatectomy (RALP) until long-term follow-up data for RALP is available.

    ABSTRACT: Background and purpose: Laparoscopic radical prostatectomy (LRP) is an established treatment option for patients with prostate cancer in selected centres with appropriate expertise. The goal of LRP is to achieve excellent cancer control whilst attempting to preserve normal urinary continence and erectile function. We studied our single-centre experience evaluating the oncological outcomes in patients undergoing LRP.

    ABSTRACT: To determine the 5-year oncological outcomes of endoscopic extraperitoneal radical prostatectomy (EERPE) from a medium-volume centre, thereby providing much needed data on outcomes from the UK. From January 2006 to January 2012, 575 patients underwent EERPE for localized prostate cancer, performed by a single surgeon who had completed a modular training programme. Follow-up was as per local hospital policy and data were collected in our prospective database. A retrospective review of patient demographics, prostate-specific antigen (PSA) levels, pathological T stages, Gleason scores, surgical margin status and biochemical recurrence (BCR) data was performed. BCR was defined as PSA >0.2 μg/L. The mean (range) patient age was 62 (40.3-76.5) years and the mean (range) follow-up was 30 (12-72) months. The median (interquartile range [IQR]) operating time was 135 (120-170) min and the median (IQR) blood loss was 200 (100-250) mL. Of the 575 patients, 135 (23.5%) had positive surgical margins (PSMs). The PSM rate for pT2 disease was 66/406 patients (16.3%) and for pT3 disease it was 68/168 patients (40.5%). Overall BCR-free survival at 5-years was 81.5%. Multivariate Cox analysis showed that PSMs, Gleason score, D'Amico risk category and pT stage were independent predictors of BCR-free survival. This assessment of the oncological results of EERPE, which included the surgical learning curve, shows that the adoption of EERPE after mentored fellowship training translates into mid-term oncological outcomes in line with those of retropubic/transperitoneal laparoscopic approaches and with large-volume centres worldwide which have pioneered laparoscopic radical prostatectomy. The study shows that EERPE in a medium-volume second generation laparoscopic centre (that introduced EERPE after adequate training in pioneering centres) produces results with good 5-year oncological outcomes, similar to those of other major series, for patients in the UK.

    ABSTRACT: PURPOSE: The purpose of the study is to characterise the clinicopathological characteristics of anterior prostate cancer (APC) compared to posterior prostate cancer (PPC)s and to determine the midterm oncological outcomes of patients with APCs undergoing endoscopic extraperitoneal radical prostatectomy (EERPE). METHODS: A retrospective review was carried out on all EERPEs performed in 2009. Pathology reports (transrectal ultrasound biopsy and surgical specimen), specimen photographs, demographic details and oncological outcome data from a prospectively maintained database were reviewed. Unpaired t test, chi-squared test and Kaplan-Meier curves were used for the analysis. RESULTS: Of 139 patients identified, 53 were APCs (38 %) and 86 were PPCs (62 %). Significantly, greater number of repeat biopsies were required to diagnose APCs (p = 0.02) and they had significantly fewer positive biopsy cores (p = 0.0005). The APC group had a significantly higher PSA density (PSAd) with (<5 and 5-25 %) tumour involvement in positive cores compared to PPCs (p = 0.036 and 0.024, respectively). APCs had higher positive surgical margin (PSM) rates (p = ns), the apical margin more likely positive than PPCs (p = 0.0006). Biochemical recurrence-free survival (BRFS) for APCs at 1, 2 and 3 years was lower than PPCs, although not statistically significant (p = 0.16). CONCLUSION: In our study, APCs proved more difficult to diagnose and stage, had a higher PSM rate and a trend towards a worse bRFS than PPCs. Additionally, the use of PSAd low core involvement biopsies might aide clinicians to investigate this cohort of patients more thoroughly before advising active surveillance.
