Predictors of prostate cancer-specific anxiety following stereotactic body radiation therapy (SBRT) for clinically localized prostate cancer.

64Background: Prostate Cancer (PCa) related anxiety varies widely based on management option. SBRT offers a safe and effective treatment for localized PCa. However, there is a paucity of data regarding PCa specific anxiety following SBRT and its relationship with PSA kinetics. In this report we present the results of a mail-in survey conducted amongst the participants of our prospective institutional quality of life (QOL) trial and identify sociodemographic and disease specific predictors of anxiety. Methods: Patients with localized PCa treated with SBRT at a single institution from 2007-2018 were eligible for inclusion in this study. The Memorial Anxiety Scale for PCa (MAX-PC) survey, was mailed to 450 patients on July of 2018. Patient’s total MAX-PC score (scale 0-54) was recorded. A score of ≥ 27 was defined as significant anxiety. Disease specific as well as demographic features were analyzed for possible correlation with self-reported anxiety. Results: By August 31, 2018, 227 patients had responded t...
