Quality of Life Outcomes after Primary Treatment for Clinically Localised Prostate Cancer: A Systematic Review
Context: Current evidence-based management for clinically localised prostate cancer includes active surveillance, surgery, external beam radiotherapy (EBRT) and brachytherapy. The impact of these treatment modalities on quality of life (QoL) is uncertain. Objective: To systematically review comparative studies investigating disease-specific QoL outcomes as assessed by validated cancer-specific patient-reported outcome measures with at least 1 yr of follow-up after primary treatment for clinically localised prostate cancer. Evidence acquisition: MEDLINE, EMBASE, AMED, PsycINFO, and Cochrane Library were searched to identify relevant studies. Studies were critically appraised for the risk of bias. A narrative synthesis was undertaken. Evidence synthesis: Of 11. 486 articles identified, 18 studies were eligible for inclusion, including three randomised controlled trials (RCTs; follow-up range: 60-72 mo) and 15 nonrandomised comparative studies (follow-up range: 12-180 mo) recruiting a total of 13. 604 patients. Two RCTs recruited small cohorts and only one was judged to have a low risk of bias. The quality of evidence from observational studies was low to moderate. For a follow-up of up to 6 yr, active surveillance was found to have the lowest impact on cancer-specific QoL, surgery had a negative impact on urinary and sexual function when compared with active surveillance and EBRT, and EBRT had a negative impact on bowel function when compared with active surveillance and surgery. Data from one small RCT reported that brachytherapy has a negative impact on urinary function 1 yr post-treatment, but no significant urinary toxicity was reported at 5 yr. Conclusions: This is the first systematic review comparing the impact of different primary treatments on cancer-specific QoL for men with clinically localised prostate cancer, using validated cancer-specific patient-reported outcome measures only. There is robust evidence that choice of primary treatment for localised prostate cancer has distinct impacts on patients' QoL. This should be discussed in detail with patients during pretreatment counselling. Patient summary: Our review of the current evidence suggests that for a period of up to 6 yr after treatment, men with localised prostate cancer who were managed with active surveillance reported high levels of quality of life (QoL). Men treated with surgery reported mainly urinary and sexual problems, while those treated with external beam radiotherapy reported mainly bowel problems. Men eligible for brachytherapy reported urinary problems up to a year after therapy, but then their QoL returned gradually to as it was before treatment. This is the first systematic review comparing the impact on cancer-specific quality of life (QoL) of different primary treatments for clinically localised prostate cancer (PCa), using validated cancer-specific patient-reported outcome measures only. There is robust evidence that the choice of primary treatment for localised PCa has a distinct impact on patients' QoL. These aspects should be discussed in detail with patients during pretreatment counselling.
