Predictors of multidomain decline in health‐related quality of life after stereotactic body radiation therapy (SBRT) for prostate cancer

BACKGROUND Stereotactic body radiation therapy (SBRT) for localized prostate cancer involves high‐dose‐per‐fraction radiation treatments. Its use is increasing, but concerns remain about treatment‐related toxicity. The authors assessed the incidence and predictors of a global decline in health‐related quality of life (HRQOL) after prostate SBRT. METHODS From 2008 to 2014, 713 consecutive men with localized prostate cancer received treatment with...
