Purpose: Depression is a debilitating illness with symptoms that overlap those of cancer and radiotherapy. We sought to measure the frequency of depression in adult radiation oncology patients.
Methods and materials: The Beck Depression Inventory-II (BDI-II) was incorporated into routine clinical evaluation of patients. Results were analyzed by univariate analysis and multivariate analysis of variance (MANOVA).
Results: One hundred twenty-four patients were screened and 19 (15%) endorsed significant depressive symptoms. Of these, levels of depression were: 58% mild, 32% moderate, and 10% severe. Twenty-six percent of the depressed group had a history of previous psychiatric diagnoses and 32% previously had been placed on psychotropic medications. The most frequent somatic symptoms for the entire group were loss of energy (73%) and tiredness or fatigue (69%). All depressed patients endorsed some somatic symptoms, but these alone were insufficient to score in the range of depression.
Conclusions: A simple tool can be administered in the clinic by radiation oncologists to screen for depression. The frequency of depression in our patients was 15%. Somatic symptoms alone were insufficient to score as depressed.
