Background and objective

With the increase in the survival rate of patients undergoing prostate cancer surgery, management of the quality of life has become important. Particularly, since sex-related disabilities of patients immensely affect their quality of life, management of the same is of utmost necessity. This study aimed to investigate whether support from friends could play a mediating role in patients with prostate cancer, after radical prostatec-tomy, for the management of sex-related symptoms and improvement of the quality of life.

Material and methods 

This descriptive survey was conducted on 212 patients, aged 20 years or older, diagnosed with prostate can-cer, and subjected to radical prostatectomy, in two South Korean University Hospitals. Data were collected from June 20 to August 10, 2017, using self-report questionnaires. Data were analyzed using the t-test, Pearson’s correlation coefficient, and multiple regression analysis. A mediation analysis was performed according to Baron and Kenny, along with bootstrapping methods.


Patients’ quality of life was significantly correlated with the experience of sex-related symptoms (r = –0.65, P< 0.001) and support from friends (r = 0.47, P< 0.001); the latter had a significant negative correlation with the experience of sex-related symptoms (r = –0.35, P < 0.001). Support from friends showed a partial mediating effect in the correlation between the experience of sex-related symptoms and quality of life (95% CI, –0.65 to –0.06).


Our findings indicated the necessity of psychosocial nursing programs that could utilize the support from friends to improve the quality of life of patients with prostate cancer following radical prostatectomy.
