Prostatectomy with or without post-operative radiotherapy: long-term adverse effects and quality of life.

BACKGROUND

Few longitudinal studies have compared patient-reported long-term adverse effects after radical prostatectomy (RP) alone and RP followed by radiotherapy (RAD), also analyzing the effect of the development of post-treatment dysfunctions/problems (Symptom Burden) on Health-Related Quality of Life (HRQoL).

MATERIAL AND METHODS

After median seven years since RP and six years since post-RP RAD, development of EPIC-26 Domain Summary Scores (DSS Changes) and HRQoL scores (SF-12) since the pre-RP situation were evaluated in respectively 317 prostatectomized men without and in 63 patients with additional post-RP RAD. Post-treatment inter-group differences of the prevalent Symptom Burden and of the DSS Changes were calculated. Multivariable logistic regressions evaluated the associations between DSS Changes and post-treatment impaired HRQoL.

RESULTS

Compared to RP alone, post-RP RAD increased the post-treatment Symptom Burden, with least inter-group differences within the urinary irritative/obstructive and bowel domain. No significant inter-group difference emerged for the proportions of men with impaired HRQoL. The odds of impaired HRQoL increased significantly with rising DSS Changes (worsening) within the vitality/hormonal domain. Worsening within urinary incontinence and bowel domains significantly increased the odds of impaired physical QoL. High HRQoL scores before RP reduced the odds of post-treatment impaired HRQoL. Living without a partner and use of androgen deprivation therapy increased this odds.

CONSLUSIONS

Post-RP radiotherapy increases post-treatment Symptom Burden with negative, though limited impact on the patient's HRQoL. Counceling before post-RP radiotherapy should cover this possible development, taking into account the patient's social situation.
