Anxiety Disorders Among Cancer Patients: An Observational Study

Abstract

Anxiety disorders represent a significant yet often underrecognized psychological
comorbidity among cancer patients. This review summarizes recent data on the
epidemiology, etiology, presentation and treatment of ADs in patients with cancer. Based on
analyses of observational studies and literature from current patients, this review shows that
anxiety disorders affect 20-50% of patients with cancer at different stages and types. The
multidimensional order of cancer-related anxiety includes diagnosis, treatment regimen,
prognosis and individual psychological variables leading to thorough assessment and
specific intervention approach. Both cognitive-behavioral therapy, pharmacological
treatments, and comprehensive interventions are found to be effective in reducing SAD
symptoms. This article suggests that routine screening and early intervention of anxiety
disorders should be part of standard cancer care which could lead to improved quality of life,
as well as increased compliance with treatment and success in the outcome.
