Purpose: Clear and accurate information about health related quality of life outcomes for men diagnosed with prostate cancer is essential for men and their physicians to make appropriate care decisions. To determine the completeness and quality of available health related quality of life information we performed a review of health related quality of life studies, assessing what information was and was not reported.
Materials and methods: A structured literature search identified 184 relevant health related quality of life studies representing 40,931 subjects.
Results: More than 95% of health related quality of life studies did not provide key information about factors known to influence outcomes. The most common omissions included information about treatments received, followup, socioeconomic status or demographic characteristics. Most data were obtained from well educated, high income socioeconomic groups, who are generally quite healthy. More than 60% of subjects were college graduates, 85% were currently married and 43% were currently employed. While black Americans comprised 15% of men studied in the 80% of studies reporting race, little information is available on Hispanic or Asian men.
Conclusions: Most of the available prostate cancer health related quality of life literature does not describe or does not account for factors known to influence health outcomes. These omissions limit their interpretability for patients trying to make decisions about treatment. More attention should be given to fully characterizing all dimensions of care that may influence quality of life outcomes and evaluating health related quality of life in Asian and Hispanic populations. Men and physicians should exercise caution when interpreting results that do not fully account for multiple factors that influence health related quality of life.
