Health related quality of life before and after laparoscopic radical prostatectomy.J Urol. 2005 Jan; 173(1):175-9; discussion 179.JU
The viability of laparoscopic radical prostatectomy (LRP) as a surgical treatment for prostate cancer depends on oncological and health related quality of life (HRQOL) outcomes. We present a prospective assessment of HRQOL in 122 patients before and after LRP using the validated Expanded Prostate Cancer Index Composite (EPIC) questionnaire.
MATERIALS AND METHODS
EPIC data were collected preoperatively, and at 3, 6 and 12 months after LRP, and all were normalized to patient preoperative baseline responses.
Using traditional single question responses, 93.4% of patients were continent (0 to 1 pads) at postoperative month 12. Of previously potent men who underwent bilateral nerve sparing 78.9% reported engaging in sexual intercourse within postoperative year 1. However, EPIC domain scores provided a more comprehensive assessment of functional outcomes. For the urinary incontinence subdomain, the majority of functional recovery was achieved by postoperative month 6, reaching a 74% return to baseline on average. In contrast, recovery of the sexual function subdomain continued throughout postoperative year 1 (to a mean of 64%). Recovery of sexual function was not significantly affected by age or preoperative potency status, although the extent of nerve sparing was a significant predictor of outcome (mean recovery to 75% of baseline for bilateral vs 36% for no nerve sparing at 12 months, p = 0.005).
Nerve sparing LRP provides satisfactory first year HRQOL outcomes when assessed with a validated instrument. The time course and extent of functional recovery documented in this prospective study may prove useful for patient counseling before LRP.
