Background: We prospectively assessed whether Psychological factors such as anxiety and depression can have a detrimental effect on long term overall survival of prostate cancer patients (pts). Methods: Prostate cancer pts participating in an ethics Committee approved, Prospective study evaluating an Andropause rating scale. All pts had radical radiotherapy with androgen deprivation therapy. Pts completed a baseline HADS questionnaire before any treatment was initiated & at 3mths & after completion of hormone therapy. Patient characteristics: Median age: 69 yrs (50 to 78 yrs). Charlson Comorbidity Index (CCI) prevalence at baseline as follows CCI-I 6.1%; CCI-II: 33.8%; CCI-III: 37.2%; CCI-IV: 14.2%; CCI-V: 6.1% and CCI-VI: 2.7%.; At the survival update in Feb 2023, 49.3% of patients have died [n = 148]; Gleeson grade was Low risk in 7.2%; Intermediate in 53.4% and high risk in 39.2%; Baseline PSA was < 10 ug/L in 45.3%; 10-20 ug/L in 33.1% and > 20 ug/L in 21.6% ; Tumour stage was T1 in 8.1% ; T2 in 63.5% and T3 in 28.4%. Baseline Median serum testosterone was 11.9 nmol/l (min 2.6 and max 26.7). Hormone duration was < 3 mths in 22.3%; 3-6mths in 35.8% ; 6 to < 36mths in 19.6% and > 36mths in 22.3%. Cox regression models estimated hazard ratios (HR) and 95% confidence intervals (CI) of overall mortality, while controlling for the following covariates (Age, T stage, Gleeson risk category, PSA Category, Baseline Serum Testosterone, ADT duration category and Charlson Comorbidity index). Results: Higher anxiety at time of diagnosis had a statistically significant adverse effect on overall survival (table); Higher depression symptoms at baseline did not affect survival but depressive symptoms after completing cancer treatment did affect all-cause mortality in this mature dataset with a median follow up of more than 11 years. Conclusions: Higher anxiety and depression symptoms in prostate cancer patients are associated with significantly higher long-term all-cause mortality.
