Randomized Controlled Trial Multicenter Study
Efficacy and safety of onabotulinumtoxinA in patients with urinary incontinence due to neurogenic detrusor overactivity: a randomised, double-blind, placebo-controlled trial.
Neurogenic detrusor overactivity (NDO) frequently results in urinary incontinence (UI) which impairs quality of life (QOL) and puts the upper urinary tract at risk. ⋯ OnabotulinumtoxinA significantly reduced UI and improved urodynamics and QOL in MS and SCI patients with NDO. Both doses were well tolerated with no clinically relevant differences in efficacy or duration of effect between the two doses (http://www.clinicaltrials.gov; NCT00461292).

Long-term results with salvage radiotherapy (SRT) for a biochemical recurrence after radical prostatectomy (RP) are poor. It has been suggested that radiotherapy doses >70 Gy might result in improved outcome. ⋯ IMRT allows for safe dose escalation to 76Gy with good bRFS.

Although benign prostate hyperplasia (BPH) and prostate cancer (PCa) share features such as hormone-dependent growth and response to treatment with antiandrogen therapy, BPH is generally not considered a premalignant lesion. ⋯ In Danish men followed for up to 27 yr, clinical BPH was associated with a two- to three-fold increased risk of PCa incidence and with a two- to eight-fold increased risk of PCa mortality. These data should not be used to infer causality.

Minimally invasive radical cystectomy (MIRC) techniques for the treatment of muscle-invasive bladder cancer (BCa) are being increasingly applied. MIRC offers the potential benefits of a minimally invasive approach in terms of reduced blood loss and analgesic requirements whilst striving to provide similar oncologic efficacy to open radical cystectomy (ORC). Whether quicker recovery, shorter hospital stay, and a reduction in complications are routinely achieved with MIRC remains to be proved in prospective comparisons. ⋯ Robotic and laparoscopic cystectomy has a growing role in the management of muscle-invasive BCa. Long-term oncologic results are awaited, and there are concerns over the ability of MIRC to treat bulky and locally advanced disease, making careful patient selection vital. Forthcoming randomised trials in this area will more fully address these issues.

Prostate cancer (PCa) is one of the most common human malignancies and arises through genetic and epigenetic alterations. Epigenetic modifications include DNA methylation, histone modifications, and microRNAs (miRNA) and produce heritable changes in gene expression without altering the DNA coding sequence. ⋯ Altered epigenetic gene regulation is involved in the genesis and progression of PCa. Epigenetic alterations may provide valuable tools for the management of PCa patients and be targeted by pharmacologic compounds that reverse their nature. The potential for epigenetic changes in PCa requires further exploration and validation to enable translation to the clinic.
