BACKGROUND
Patients with cancer are particularly vulnerable to depressive experiences, ranging from severe emotional reactions to proper depressive syndromes, including major depression. These experiences may deeply affect the course and outcome of the disease. The aim of this study was to assess the efficacy acceptability of antidepressants on the continuum of depressive experiences in patients suffering from cancer.
METHODS
MEDLINE, EMBASE, PsycINFO, CENTRAL, as well as websites of regulatory agencies, clinical trial repositories and pharmaceutical companies, were systematically searched for published and unpublished randomised trials assessing the efficacy of antidepressants versus placebo in patients with cancer. Efficacy of antidepressants at the end of the study was the primary outcome. The review protocol was registered with PROSPERO (CRD42014013440).
RESULTS
A total of 19 studies contributed to the analysis. Antidepressants (particularly the selective serotonin-reuptake inhibitors and mianserin) were more effective than placebo in relieving depressive experiences in both patients with major depression or depressive symptoms (standardised mean difference -0.596, 95% confidence interval -1.041 to -0.150), as well as in patients with other cancer-related distressing symptoms (standardised mean difference -0.229, 95% confidence interval -0.419 to -0.039). We found evidence that efficacy was positively associated with length of treatment. No differences between antidepressants and placebo were found in terms of overall acceptability.
CONCLUSIONS
Antidepressants should be considered as one treatment option for relieving the burden of depressive experiences in patients with cancer.
