The role of transperineal template prostate biopsies in restaging men with prostate cancer managed by active surveillance.

OBJECTIVE: To evaluate the role of transperineal template prostate biopsies in men on active surveillance. PATIENTS AND METHODS: In all, 101 men on active surveillance for prostate cancer underwent restaging transperineal template prostate biopsies at a single centre. Criteria for active surveillance were ≤75 years, Gleason ≤3+3, prostate-specific antigen (PSA) ≤15 ng/mL, clinical stage T1-2a and ≤50% ultrasound-guided transrectal biopsy cores positive for cancer with ≤10 mm of disease in a single core. The number of men with an increase in disease volume or Gleason grade on transperineal template biopsy and the number of men who later underwent radical treatment were assessed. The role of PSA and PSA kinetics were studied. RESULTS: In all, 34% of men had more significant prostate cancer on restaging transperineal template biopsies compared with their transrectal biopsies. Of these men, 44% had disease predominantly in the anterior part of the gland, an area often under-sampled by transrectal biopsies. In the group of men who had their restaging transperineal template biopsies within 6 months of commencing active surveillance 38% had more significant disease. There was no correlation with PSA velocity or PSA doubling time. In total, 33% of men stopped active surveillance and had radical treatment. CONCLUSIONS: Around one-third of men had more significant prostate cancer on transperineal template biopsies. This probably reflects under-sampling by initial transrectal biopsies rather than disease progression.

Are prostatic biopsies necessary in men aged > or =80 years?

OBJECTIVE: To examine whether prostatic biopsies are necessary in all men aged > or =80 years, as men found to have prostate cancer are frequently treated with a 'watch and wait' policy or with hormonal withdrawal alone, and biopsies are associated with a small but significant complication rate. PATIENTS AND METHODS: The findings on a digital rectal examination (DRE), the prostate-specific antigen (PSA) level, the biopsy and staging bone scan results for all men aged > or = 80 years who had prostatic biopsies over a 3-year period were reviewed, together with those in a group of men aged <80 years for comparison. All biopsy samples had been examined in one of three histopathology units, and 33 consultant urological surgeons contributed. RESULTS: In all, 210 biopsies from 205 men aged > or = 80 years were identified, of whom 163 (79%) had biopsy-confirmed prostate cancer. All 29 men with a PSA level of > or = 100 ng/mL, 98% of 47 with > or = 50 ng/mL, 97% of 76 with > or = 30 ng/mL and 92% of 101 with > or = 20 ng/mL had biopsy cores containing cancer; 63% of men with a PSA level of <20 ng/mL had cancer on biopsy. In men with cancer and a PSA level of > or = 30 ng/mL, 92% had Gleason grade > or = 7 and 93% were treated with hormonal withdrawal alone. In all men with cancer the DRE was abnormal in 91%, the mean number of positive cores was 59% and the bone scan was positive in 18%. The DRE was abnormal in 77% of men with benign biopsies. CONCLUSIONS: In men aged > or = 80 years with a PSA level of > or = 30 ng/mL, at least 97% had prostate cancer, >90% of whom had high-grade disease, and nearly all with cancer received active pharmacological treatment. In the vast majority of these men prostate biopsies did not alter their cancer management. The value of prostatic biopsy in this age group, with a PSA level of > or = 30 ng/mL, is questionable.

Extensive transperineal template biopsies of prostate: modified technique and results.

OBJECTIVES: To describe the modified technique and results of extensive transperineal template prostate biopsies in men with a high risk of prostate cancer in whom repeated transrectal biopsies are not diagnostic. METHODS: Men who had a rising prostate-specific antigen (PSA) level and had at least two sets of benign octant biopsies or two or more prior biopsies containing high-grade prostatic intraepithelial neoplasia or atypical small acinar proliferation were included. A biplanar transrectal ultrasound probe was attached to a brachytherapy stepping unit and a standard 0.5-cm brachytherapy template was positioned over the perineum. In the transverse image, the prostate was divided into right and left and anterior, middle, and posterior regions, and three to five transperineal biopsy cores were taken in each of the six regions through the template. RESULTS: Sixty men underwent extensive transperineal template biopsies. Their mean age was 64 years (SD 6.4), the median PSA level was 12.9 ng/mL (range 4.6 to 35.7), and the median prostate volume was 54 cm3 (range 34 to 199). Cancer was detected in 23 men (38%), of whom 17 (74%) had Gleason grade 6, 5 (21%) Gleason grade 7, and 1 (4%) Gleason grade 9 disease. Cancer was identified in the anterior region of the prostate alone in 12 men (60%). One man required overnight admission for hematuria and two developed urinary retention; no cases of sepsis developed. CONCLUSIONS: In men with a clinical suspicion of prostate cancer, but benign or equivocal prostate biopsies, extensive transperineal template biopsy of the prostate is a useful diagnostic tool. It allows sampling of the whole prostate in a systematic and safe fashion.

The surgical risk of suprapubic catheter insertion and long-term sequelae.

INTRODUCTION: Suprapubic catheter (SPC) insertion is a common urological procedure, which is often referred to as safe and simple even in inexperienced hands. There is, however, very little published evidence on the safety of this procedure. Our study aimed to provide evidence on the associated morbidity and mortality and provide guidance for practising clinicians. PATIENTS AND METHODS: A total of 219 patients who underwent SPC insertion under cystoscopic guidance at two urology institutions between 1994 and 2002 were identified and their case notes reviewed. RESULTS: The intra-operative complication rate was 10% and the 30-day complications rate was 19%. Mortality rate was 1.8%. Long-term complications included recurrent UTIs (21%), catheter blockage (25%) resulting in multiple accident and emergency attendance (43%). Despite this, the satisfaction rate was high (72%) and most patients (89%) prefer the SPC over the urethral catheter. CONCLUSIONS: SPC bladder drainage results in a high patient satisfaction rate. Patients and clinicians should be aware of the potential complications associated with SPC insertion.
