Are we missing PTSD in our patients with cancer? Part I

摘要

Posttraumatic Stress Disorder (PTSD) can be defined by the inability to recover from a traumatic event. A common misconception is that PTSD can only develop in circumstances of war or acute physical trauma. However, the diagnostic criteria of PTSD were adjusted in the Diagnostic Statistical Manual of Mental Disorders Fourth Edition (DSM-IV) to include the diagnosis and treatment of a life-threatening illness, such as cancer, as a traumatic stressor that can result in PTSD. The word ‘cancer’ is so strongly linked to fear, stigma, and mortality, that some patients are fearful to even say ‘the C word’. Therefore, it is not surprising that patients may experience a diagnosis of cancer as sudden, catastrophic, and/or life-threatening. Cancer-related PTSD (CR-PTSD) can negatively affect a patient’s psychosocial and physical well-being during treatment and into survivorship. Unfortunately, CR-PTSD often goes undiagnosed and, consequentially, untreated. This article provides a general overview of PTSD with cancer as the traumatic event in order to define CR-PTSD, and reviews the growing pool of literature on this topic, including prevalence, risk factors, characterization, and treatment of CR-PTSD. The purpose of this article is to spread awareness of this relatively newly defined and commonly missed disorder among patients with cancer to clinicians and patients alike.
