Summary

For many patients with cancer, becoming depressed is frequently associated with both the cancer and its treatments. In a recent state-of-the-science conference, depression was highlighted as one of the most important symptoms facing patients with cancer, along with fatigue and pain. Only a small proportion of patients with cancer present with major depression as defined by the revised fourth version of the Diagnostic and Statistical Manual of Mental Disorders (DSM-IVR), but depression-like symptoms, including reduced interest in previously pleasurable activities, lack of motivation, and sadness are frequently reported by patients with cancer in various stages of the disease.

It is easy to attribute these changes in affect to the patient learning that they have a potentially fatal disease. However, the degree of disturbance reported by patients is typically only modestly correlated with the severity of their disease or their prognosis. Only recently has there been interest in the association between the biological insults caused by cancer and its treatment, and the changes in affect and the other symptoms that patients report. Having a greater understanding of the biology contributing to cancer-related changes in affect should lead to better control or prevention of this source of distress.

Animal models of depressed affect related to disease burden or treatment toxicities may be important for developing a mechanistic understanding of why these changes occur. Currently, animal models of depressed affect related to cancer are relatively unexplored (but see below).
