Is There a Difference in the Incidence of Depression between Radiation and Surgical Treatments in Patients with Prostate Cancer?

초록

Purpose: Patients with cancer have a high risk of depression. However, a few studies have assessed differences in the inci-dence of depression among patients with prostate cancer (PC) based on whether they received radiotherapy (RTx) or surgical treatment.Materials and Methods: We analyzed data from the National Health Insurance Sharing Service database regarding the entire Korean adult population with PC (n=210,924) between 2007 and 2017. The adjusted hazard ratios (HRs) of depression as-sociated with treatment were estimated using propensity score-matched Cox proportional hazards models and Kaplan-Meier survival analyses.Results: Our final cohort comprised 9,456 patients with PC; of which, 8,050 men underwent surgery. During a mean follow-up duration of 7.1 years, 503 (5.3%) patients were newly diagnosed with depression. A significant difference in the incidence of depression was noted between the RTx and surgery groups (RTx vs. surgery: 5.55% vs. 5.28%; p=0.011) in the unmatched cohort. In the matched cohort, older age (>= 70 years, HR: 1.596, p<0.001) and poor Charlson comorbidity index scores (HR: 1.232, p=0.039) were correlated with the risk of depression. In addition, the adjusted HR for depression in the surgery group was 0.843 (p=0.221) compared with that in the RTx group. Kaplan-Meier analyses revealed that no significant difference in the cumulative probability of persistent depression was detected between the RTx and surgery groups in matched cohort (p=0.3386).Conclusions: In this nationwide population-based study, no significant differences in the risk of depression were observed between the surgical and RTx groups.
