We followed a prespecified search protocol (PROSPERO identifier CRD42014009173) to identify studies that evaluated patient preferences for prostate cancer management options for localized prostate cancer. We queried PubMed, the Cochrane Database of Systematic Reviews, Embase, Cumulative Index to Nursing & Allied Health Literature (CINAHL) Plus, and Econ-Lit databases. Two separate reviewers completed the article selection process and review, including coding of study characteristics. Study quality was scored according to the PREFS checklist, which consists of five criteria: Purpose, Respondents, Explanation, Findings, and Significance. Reviewers summarized the primary findings of each article included in the analysis.
Of the 606 citations identified in the literature search, there were a total of 21 articles that met all selection criteria, reporting results for a total of 4,131 subjects. Themes identified in the studies included: the importance of patient perceptions of treatment efficacy and side effects; the influence of physician recommendations on patient decision-making; and the prioritization of concerns regarding treatment side effects among those men who prefer radiation therapy or active surveillance. The articles had an average PREFS score of 3.4 (standard deviation [SD] 1.0), which is similar to a recent study for breast cancer treatment preferences.
This systematic review of factors that influence patient preferences for prostate cancer management options identified a small, but high quality, group of articles that satisfied the selection criteria. The available evidence suggests that interventions aimed at informing patients regarding the comparative effectiveness of prostate cancer management alternatives should include the influence of physician recommendations and family members' desires on patient decision-making.
