Abstract

PURPOSE:

The aims of the present study were to assess the prevalence of depressive symptoms at diagnosis, test the association between depressive symptoms and survival, and preliminarily test a mediational model of depression, immunity, and survival in patients with hepatobiliary carcinoma (HBC).

PATIENTS AND METHODS:

One hundred one patients diagnosed with HBC were prospectively studied. Depressive symptoms were measured at diagnosis using the Center for Epidemiological Studies Depression Scale (CES-D). Sociodemographic and disease-specific data were gathered from the patients' charts. In a subsample of patients, stress; alcohol, tobacco, and drug use; sleep quality; physical activity; social support; natural killer (NK) cell number and cytotoxicity; and plasma levels of interleukin (IL) -4, IL-5, tumor necrosis factor alpha, and interferon gamma were measured. Survival was measured from date of diagnosis to death.

RESULTS:

At diagnosis, 37% of patients reported a CES-D score of > or = 16 (clinical range). Using Cox regression analysis, sociodemographic and disease-specific variables and CES-D score significantly predicted survival (Breslow chi2 = 32.4, P = .006). Only vascular invasion (P = .001) and CES-D score > or = 16 (P = .03) were significant predictors. In a subsample of 23 patients, patients who reported a CES-D score of > or = 16 were found to have significantly lower NK cell numbers than patients who reported a CES-D score of less than 16 (F1,21 = 9.39, P = .003). A robust trend was found in which NK cell number was associated with survival. A mediational model linking depressive symptoms and survival, with NK cell number as a mediator, was preliminarily supported.

CONCLUSION:

Secondary to the high prevalence of depressive symptoms and impact on survival, psychological and pharmacologic interventions should be designed and implemented in patients diagnosed with HBC.
