A screening algorithm for early detection of major depressive disorder in head and neck cancer patients post-treatment: Longitudinal study

Abstract

Objective: The primary purpose of this study was to identify predictors of Major Depressive Disorder in head and neck cancer (HNC) patients in the immediate post-treatment period (ie, at 3 months post-diagnosis), with a focus on previously unexamined historical and contextual factors.

Methods: Prospective longitudinal study of 223 consecutive adults (72% participation) newly diagnosed with a first occurrence of primary HNC, including validated psychometric measures, Structured Clinical Interviews for DSM Disorders, and medical chart reviews.

Results: The 3-month period prevalence of Major Depressive Disorder was 20.4%; with point prevalences of 6.8% upon HNC diagnosis, 14.2% at 3 months, and 22.6% lifetime. Patients most susceptible to developing Major Depressive Disorder in the immediate post-treatment period: were diagnosed with advanced-stage cancer rather than early-stage cancer (O.R. = 4.94, P = 0.04), received surgery only (O.R. = 8.73, P = 0.04), presented a lifetime history of Anxiety Disorder on SCID-I (O.R. = 6.62; P = 0.01), and indicated higher pre-treatment levels of anxiety on the HADS (O.R. = 0.45, P = 0.05).

Conclusions: Our results outline the predominant role of anxiety upon diagnosis as a precursor to post-treatment Major Depressive Disorder, suggesting the need for identification and prophylactic treatment of anxiety upon diagnosis in head and neck cancer patients. Further investigation into pathways by which pre-treatment anxiety predisposes to post-treatment Major Depressive Disorder in this population is warranted.
