Background Cancer patients are at increased risk for depression compared with individuals with no cancer diagnosis, yet few interventions target depressed cancer patients. Methods Efficacy of psychotherapeutic and pharmacologic interventions for depression in cancer patients who met an entry threshold for depressive symptoms was examined by meta-analysis. Five electronic databases were systematically reviewed to identify randomized controlled trials meeting the selection criteria. Effect sizes were calculated using Hedges' g and were pooled to compare pre-and postrandomization depressive symptoms with a random effects model. Subgroup analyses tested moderators of effect sizes, such as comparison of different intervention modalities, with a mixed effects model. All statistical tests were two-sided. Results Ten randomized controlled trials (six psychotherapeutic and four pharmacologic studies) met the selection criteria; 1362 participants with mixed cancer types and stages had been randomly assigned to treatment groups. One outlier trial was removed from analyses. The random effects model showed interventions to be superior to control conditions on reducing depressive symptoms postintervention (Hedges' g = 0.43, 95% confidence interval = 0.30 to 0.56, P <. 001). In the four psychotherapeutic trials with follow-up assessment, interventions were more effective than control conditions up to 1218 months after patients were randomly assigned to treatment groups (P <. 001). Although each approach was more effective than the control conditions in improving depressive symptoms (P <. 001), subgroup analyses showed that cognitive behavioral therapy appeared more effective than problem-solving therapy (P =. 01), but not more effective than pharmacologic intervention (P =. 07). Conclusions Our findings suggest that psychological and pharmacologic approaches can be targeted productively toward cancer patients with elevated depressive symptoms. Research is needed to maximize effectiveness, accessibility, and integration into clinical care of interventions for depressed cancer patients.
