Psychobiological screening among patients affected by prostate cancer: Identification of potential psychobiological markers

Abstract

Prostate cancer is a common oncological disease of old age with the highest rates of incidence among males older than 65 years old. Diagnosis and treatment may be associated with the onset of adjustment, depressive, and anxiety disorders. The comorbidity with depression and anxiety may lead to a higher risk of suicide, and mortality as well as lower adherence to medical treatments and adverse functional outcomes in patients affected by urologic cancers. The role of genetic vulnerability and pre-morbid personality in predicting the development of mental disorders during cancer disease is debated. For instance, some genetic polymorphisms of the serotonin transporter-related promoter region (5-HTTLPR polymorphism) are associated with higher vulnerability for mental disorders as well as personality traits of neuroticism; both factors are potentially useful for identifying risk of depressive and anxious symptoms among cancer patients. This communication proposes the development of individualized psychobiological approaches to identify possible ‘psychobiological’ markers associated with the risk of mental disorders in prostate cancer patients.
