[Behavioral group-based therapy improves quality of life in men recovering from radical prostatectomy].
BACKGROUND
This study evaluated the efficacy of 24-week, group-based, behavioral therapy in improving quality of life (QoL) among men treated for localized prostate carcinoma (PC) by means of radical prostatectomy (RP) who presented treatment-related dysfunctions: urinary incontinence (UI) and erectile dysfunction (ED).


METHODS
Thirty men were assigned to 24-week behavioral group therapy. The intervention was designed to improve QoL by helping participants to identify and effectively manage stressful experiences. It focused on treatment-related sequelae from PC. Differences in variables were compared between the beginning and end of the study by means of Student's t test for paired samples. Multiple analysis was carried out by stepwise multiple linear regression following bivariate Pearson's correlation analysis. This was achieved for all predictors (i.e. general health perception, ED and UI impact) and relevant covariates (i.e. age, work/retirement status, alcohol addiction, attitude towards cancer and surgery, sexual satisfaction, and future plans).


RESULTS
In all patients the time elapsed from surgery to attending the behavioral group therapy exceeded 24 months. There was no significant correlation between this time and the predictor variables. General health perception scores decreased by the end of the study (p = 0.000), as did the UI impact score (p = 0.023), thus denoting improvement in both factors. The difference in UI impact scores correlated negatively and significantly with both age (p = 0.04) and work/retirement (p = 0.05). Multiple stepwise regression showed that age was the most important variable (r2 = 26.0%). Considering age and work/retirement simultaneously, there was an increase of 10.3% (r2 = 36.3%). ED increased by the end of the study (p = 0.000), and the difference between the ED scores correlated positively and significantly with sexual satisfaction alone (p = 0.029), which signifies that previous sexual satisfaction had a positive influence over erectile dysfunction (r2 = 15.8%).


CONCLUSIONS
24-week behavioral group therapy was effective in improving the perceived QoL among men treated for PC. There were changes associated with the therapy, particularly the improvement in UI and ED.
