Kaplan-Meier Survival Curve Modeled for Time to Death from Enrollment stratified by Primary Outcome of Moderate or Greater Depression.
Objective
To study the association between the development of moderate or greater depression during curative-intent therapy and overall survival (OS) in patients with stages II-IV head and neck cancer (HNC).
Methods
In this secondary analysis of a randomized double-blind placebo-controlled trial, of 148 eligible participants diagnosed with stages II-IV HNC but without baseline depression, 125 were evaluable and were randomly allocated to prophylactic escitalopram oxalate (n = 60) or placebo (n = 65). Participants were followed for development of moderate or greater depression, using Quick Inventory of Depressive Symptomatology-Self Report (QIDS-SR, range 0–27, score ≥11 indicated moderate or greater depression), and were stratified by demographics; cancer site and stage; and primary treatment modality (surgery with or without radiotherapy vs. radiotherapy with or without chemotherapy). Single variable and multivariable Cox proportional-hazard models were used to evaluate differences in OS.
Results
Clinically significant depression developed in 22 of 125 patients (17.6%) during HNC treatment. The mean follow-up was 5.0 years (SD 2.4). OS was similar for patient groups, when stratified by development of moderate or greater depression (HR 0.54 [CI, 0.21–1.43]) or use of prophylactic antidepressant (HR 0.64 [CI, 0.34–1.21]).
Conclusion
There was no significant association between OS and development of moderate or greater depression in patients being treated for stages II-IV HNC, or between OS and use of prophylactic antidepressant escitalopram. Prophylactic antidepressant may be considered in patients with HNC for prevention of clinically significant depression and may offer improved quality of life outcomes.
