New innovative therapies for benign prostatic hyperplasia: any advance?

Abstract:

PURPOSE OF REVIEW:Benign prostatic hyperplasia is the most common human neoplasm and it is the most frequent tumour requiring surgical treatment in men. Not surprisingly, interest centres on either understanding of prostatic growth during ageing or on various medical or interventional treatments. RECENT FINDINGS:Recent publications describe the interaction of various 5alpha-reductase inhibitors on the two 5alpha-reductase isoforms type 1 and 2, giving a potential new insight into the pathogenesis of benign prostatic hyperplasia. Likewise, chronic inflammation increases growth patterns of fibromuscular tissue in benign prostatic hyperplasia similar to wound healing, and a paracrine loop for chronic inflammation with overexpression of interleukin could be identified. This could be of particular importance in the further understanding of prostatic enlargement. Herbal drug treatment for lower urinary tract symptoms seems to be more effective than previously thought. According to recent publications the effectiveness is well beyond placebo effects. Likewise, alpha-blockers play an important role in treatment of lower urinary tract symptoms with alpha-1 adrenoreceptor antagonists preventing cell proliferation and apoptotic imbalances in prostatic tissue. The effect of alpha-blockers, however, may be limited by severe bladder outlet obstruction with patients at increased risk of treatment failure. Laser prostatectomy and microwave thermotherapy are under consideration as alternative treatments of benign prostatic hyperplasia. The efficacy of urodynamically proven de-obstruction as compared with transurethral resection of the prostate needs to be evaluated. Newer alternative treatments like ethanol installation or bipolar plasma kinetic vaporization have been described, but long-term results and larger patients cohort are still lacking. SUMMARY:New insights into prostatic growth and pathogenesis of benign prostatic hyperplasia are presented. Medical treatment and interventional therapies are evaluated for their safety and efficacy. Only a few new therapeutical options, however, have been published during this review period.
