OBJECTIVE: To examine the associations between pharmaceutically treated anxiety and depression and incident cardiovascular disease (CVD) among 1-year prostate cancer survivors. PATIENTS AND METHODS: A registry-based cohort study design was used toescribe the risk of incident CVD in adult 1-year prostate cancer survivors without a history of CVD. Prostate cancer patients diagnosed between 1999 and 2011 were selected from the Netherlands Cancer Registry. Drug dispenses were retrieved from the PHARMO Database Network and were used as proxy for CVD, anxiety, and depression. Data was analyzed using Cox regression analysis to examine the risk associations between pharmaceutically treated anxiety and depression entered as a time-varying predictor withincident CVD in 1-year prostate cancer survivors, while controlling for age, traditional CVD risk factors, and clinical characteristics. RESULTS: Of the 5262 prostate cancer survivors, 327 (6%) developed CVD during the 13-year follow-up period. Prostatecancer survivors who were pharmaceutically treated for depression had an increased risk of incident CVD after full adjustment compared to prostate cancer survivors who were not pharmaceutically treated for depression (HR=1.51;95%CI=1.06-2.15). The increased risk of incident CVD among those pharmaceutically treated for depression compared to those who were not pharmaceutically treated for depression, was only valid among: prostate cancer survivors who were 65 years or younger (HR=2.91;95%CI=1.52-5.55); those who were not treated with radiotherapy (HR=1.63;95%CI=1.01-2.65); those who were treated with hormones (HR=1.76;95%CI=1.09-2.85); those who were not operated upon (HR=1.55;95%CI=1.07-2.25); and those with tumor stage III (HR=2.21;95%CI=1.03-4.74) and stage IV (HR=2.47;95%CI=1.03-5.89). CONCLUSION: Prostate cancer patients who were pharmaceutically treated for depression had a 51% increased risk of incident CVD after adjustment for anxiety, age, traditional CVD risk factors, and clinical characteristics. The results emphasize the need to pay attention to (pharmaceutically treated) depressed prostate cancer patients prior to deciding on prostate cancer treatment and for a timely detection and treatment of CVD.
