Antidepressant medication use and nasopharyngeal cancer risk: a nationwide population-based study.

Background: The association between antidepressant exposure and nasopharyngeal cancer (NPC) has not been previously explored. The purpose of this study was to investigate the association between antidepressant prescription, including novel antidepressants, and the risk of NPC in a population-based study. Materials and methods: Data for the analysis were derived from National Health Insurance Research Database. We identified 16,957 cases with a diagnosis of NPC and 83,231 matched controls by using a nested case-control design. A conditional logistic regression model was used, with adjustments for potentially confounding variables (eg, comorbid physical diseases, comorbid psychiatric diseases, and other medications). Results: We report no association between NPC incidence and antidepressant prescription. For all classes of antidepressants, antidepressant exposure, regardless of cumulative dose, had no significant effect on NPC incidence (adjusted odds ratio of cumulative selective serotonin reuptake inhibitor exposure >= 336 defined daily dose was 1.18 [95% CI: 0.90-1.53]; tricyclic antidepressant exposure >= 336 defined daily dose was 1.18 [95% CI: 0.80-1.74]). Conclusion: There was no association between antidepressant prescription and incident NPC.
