Effectiveness of Pelvic Floor Muscle and Education-Based Therapies on Bladder, Bowel, Vaginal, Sexual, Psychological Function, Quality of Life, and Pelvic Floor Muscle Function in Females Treated for Gynecological Cancer: A Systematic Review.

Abstract

Purpose of review: Gynecological malignancies are prevalent in females, and this population is likely to experience symptoms of pelvic floor disorders and sexual dysfunction. Non-surgical, non-pharmaceutical conservative therapies, namely pelvic floor muscle (PFM) therapies and education-based interventions, could be beneficial for this population. The purpose of this systematic review was to examine the evidence regarding their effectiveness on bladder, bowel, vaginal, sexual, psychological function, quality of life, and PFM function in gynecological cancer populations.

Recent findings: Six databases were searched to identify studies employing any interventional study design, except case studies, to investigate the effect of PFM therapies, education-based interventions, or combined therapies on any outcome of interest. The search yielded 4467 results, from which 20 studies were included. Of these, 11 (55%) were RCTs, two (10%) were non-RCTs with two groups, and seven (35%) were non-RCTs with a single group. Findings suggest that combined (multimodal) therapies, specifically PFM (active > passive) + education therapies, appear more effective for vaginal, overall pelvic floor, sexual, and PFM function. PFM therapies (active and/or electrostimulation) may improve bladder outcomes. Limited evidence suggests PFM (active) + education therapies may improve bowel function. Conservative therapies may improve psychological function, although available data do not appear to favor a particular therapy. Given the conflicting findings regarding quality of life, no clear conclusions can be made. Interpretation of findings highlighted the importance of intervention dosage, adherence, and supervision for optimal effectiveness. Despite the limitations of the included studies, this review provides new and valuable insights for future research and clinical practice.
