Prospective longitudinal comparative study of health-related quality of life and treatment satisfaction in patients treated with hormone therapy, radical retropubic prostatectomy, and high or low dose rate brachytherapy for prostate cancer.
OBJECTIVE
To evaluate the effects of four different prostate cancer treatments on quality of life (QoL) and patient satisfaction.


METHODS
Ninety-six prostate cancer patients were treated with hormone therapy, radical retropubic prostatectomy, high dose rate brachytherapy, or low dose rate brachytherapy. We assessed general, cancer-specific, and prostate disease-specific QoL. More than one year since commencement of treatment, the patients were asked the following questions: 1) How do you feel about your treatment? 2) Would you undergo the same treatment again?


RESULTS
The comparison of baseline and 12-month results showed that general and cancer-specific QoL had changed little in all groups. At baseline, the general and cancer-specific QoL tended to be lower in the hormone therapy patients. In the radical the retropubic prostatectomy patients, all scores on the Medical Outcomes Study 36-Item Short Form were worse than the baseline scores at three months. Scores for the International Index of Erectile Function-5 had also worsened, with no recovery. In the low-dose rate brachytherapy patients, the prostate disease-specific QoL at baseline tended to improve. However, the satisfaction levels for each treatment were reasonably good, and most patients would choose the same treatment again.


CONCLUSIONS
The results of each of the four treatments differed in assessments of QoL. In the radical retropubic prostatectomy patients, the decrease in the International Index of Erectile Function-5 scores was especially remarkable and did not show recovery. In contrast, both brachy therapy groups had attained superior sexual function. However, regardless of the quality of life evaluations, most patients surveyed were satisfied with their treatments and would choose the same treatment again.
