Disease-specific quality of life among patients with localized prostate cancer: an Australian perspective.
OBJECTIVE
To examine differences in sexual, urinary and bowel function, and bother, in patients with prostate cancer after treatment with radical prostatectomy (RP) or external beam radiation (EBRT), compared to a convenience sample of men with no diagnosis of prostate cancer, as little is known about the disease-specific health-related quality of life (HRQoL) of men in Australia after treatment for clinically localized prostate cancer.


METHODS
The study was a retrospective cross-sectional survey of 95 controls, 82 men with localized prostate cancer treated with RP and 39 with EBRT at > or = 2 years before data were collected. Disease-specific HRQoL was assessed using the University of California Los Angeles Prostate Cancer Index, a validated measure that includes six subscales addressing sexual, urinary and bowel symptoms, and level of bother associated with the symptoms. Univariate analyses were conducted to ascertain differences in disease-specific HRQoL among the three groups. To minimize the influence of other factors, age and comorbid medical conditions were included as covariates.


RESULTS
Men treated with RP had more sexual and urinary symptoms (both P < 0.001) than those treated with EBRT, and more sexual bother (P < 0.001). Men treated with EBRT reported significantly worse bowel function (P = 0.02) and more bother (P < 0.001) with these symptoms than those who had RP.


CONCLUSIONS
Except for bowel dysfunction and the bother associated with these symptoms, disease-specific HRQoL was generally worse after RP than EBRT.
