Post-surgery anxiety and depression in prostate cancer patients: prevalence, longitudinal progression, and their correlations with survival profiles during a 3-year follow-up

Abstract

Abstract Background Anxiety and depression are more frequent in cancer patients than general population and may be correlated with cancer prognosis; however, their value in prostate cancer patients is largely unknown. We aimed to evaluate prevalence of anxiety and depression in prostate cancer survivors post the surgeries, and their correlations with patients’ disease-free survival (DFS) and overall survival (OS). Methods A hundred and ninety-four patients with prostate cancer who underwent radical prostatectomy were enrolled. After discharged from hospital, patients were assessed for post-surgery anxiety and depression every 3 months using Zung Self-rating Anxiety/Depression Scale (SAS/SDS) for a total of 36 months. In addition, disease conditions, DFS, and OS were also documented. Results SAS score (P < 0.001), anxiety rate (P = 0.004), SDS score (P < 0.001), and depression rate (P < 0.001) gradually elevated from baseline to month 36 in prostate cancer patients. Anxiety at baseline (P = 0.009) and anxiety at 3 years (P = 0.017) were correlated with worse DFS, and anxiety at baseline (P = 0.009) was also correlated with shorter OS in prostate cancer patients. Furthermore, depression at baseline (P = 0.005) and depression at 2 years (P = 0.008) were associated with unfavorable DFS, and depression at baseline (P = 0.001), 1 year (P = 0.025), and 2 years (P = 0.008) were associated with worse OS in prostate cancer patients. Moreover, multivariate Cox’s proportional hazards regression analysis elucidated that depression at baseline (P = 0.027) was an independent predictive factor for shorter DFS in prostate cancer patients. Conclusion Anxiety and depression both gradually deteriorate, and they correlate with unfavorable survival profile in prostate cancer patients after radical prostatectomy.
