Currently, there is limited number of reports of health-related quality of life after prostate cancer treatment comparing IGTPB with 3D-CRT.21'22 In one cross-sectional survey study, Davis et al. studied patients treated at a single community medical center between 1995 and 1999.22 Totals of 269, 142 and 222 men who underwent radical prostatectomy, Pd103 implants and conventional external beam radiation therapy were studied using validated quality of life survey instruments. In this study, men who received conventional external beam radiation therapy reported lower bowel function and more bother with their bowels. All treatment groups reported decreased sexual function. Urinary bother scores were unaffected in all three groups. Irritative urinary symptoms were significant in men who received Pd103 brachytherapy and who were surveyed less than 1 year after treatment. In addition, satisfaction with treatment was equivalent among the treatment groups.
Unfortunately, global prospective longitudinal QOL study to assess the changes in QOL for patients treated with IGTPB and 3D-CRT is lacking. Important information from QOL assessments will allow patients and physicians to select optimal treatment that best suits their needs and lifestyle.
