Randomized Controlled Trial Multicenter Study
Bicalutamide 150 mg plus standard care vs standard care alone for early prostate cancer.
To evaluate, in the ongoing Early Prostate Cancer (EPC) trial programme, the efficacy and tolerability of bicalutamide 150 mg once daily in addition to standard care for localized or locally advanced, nonmetastatic prostate cancer. ⋯ This ongoing programme is clarifying the role of early or adjuvant antiandrogen therapy in prostate cancer. Patients with localized disease do not appear to derive clinical benefit from added bicalutamide. However, adding bicalutamide 150 mg to standard care provides significant clinical benefits in patients with locally advanced prostate cancer, irrespective of primary therapy.

To further investigate the rationale for using spinal nerve stimulation (SNS) for treating bladder overactivity associated with cystitis in a rat model of cyclophosphamide-induced cystitis, as several studies suggested that symptoms associated with chronic cystitis could be treated using stimulation of sacral spinal nerves, but the mechanisms by which it works are unknown. ⋯ SNS recruiting only Adelta-fibre produced fewer voiding contractions in cyclophosphamide-treated rats, to a level similar to that from the control rats. These results support the ability of SNS to decrease bladder overactivity in a pathophysiological model of chemical irritation of the bladder.

To determine if the International Prostate Symptom Score (IPSS) before seed implantation, stratified into mild (0-7), moderate (8-19) and severe (>20) categories, predicts brachytherapy-related morbidity in terms of IPSS resolution, catheter dependency and the need for surgical intervention after brachytherapy. ⋯ The IPSS before implantation predicted the resolution of IPSS after brachytherapy, but did not correlate with substantial urinary morbidity, including catheter dependency or the need for TURP. At 5 years after brachytherapy, 90.1% of patients at risk were assigned to the IPSS 0-7 category.

To evaluate the influence of preoperative serum prostate-specific antigen (PSA) level and other clinicopathological variables on the probability of biochemical failure and clinical recurrence after radical prostatectomy (RP) for localized prostate cancer. ⋯ In the present patients undergoing RP the preoperative serum PSA level was not associated with the clinical outcome, whereas it was significantly related to biochemical failure rate. The probability of skeletal metastases was significantly associated with the PSADT after biochemical failure.

Randomized Controlled Trial Comparative Study
Perianal and intrarectal anaesthesia for transrectal biopsy of the prostate: a prospective randomized study comparing lidocaine-prilocaine cream and placebo.
To assess the effectiveness of perianal and intrarectal lidocaine-prilocaine cream for prostate biopsy. ⋯ Topical anaesthesia with prilocaine-lidocaine cream significantly reduced pain at transrectal probe insertion and during the biopsy procedure.
