Post‐Traumatic Stress Symptoms in Head and Neck Cancer Patients: The Impact of the COVID ‐19 Pandemic and Gene–Environment Interaction

BACKGROUND: This study aimed to assess the occurrence of post-traumatic stress symptoms (PTSS) in head and neck cancer (HNC) patients. The goal also was to explore potential associations between PTSS, demographic factors, psychological variables, and specific genetic variants. METHODS: This study included a total of 155 HNC patients, divided into pre-pandemic (n = 76) and COVID-19 pandemic (n = 79) groups. PTSS assessments were conducted using a standardized questionnaire. The assessment of adverse childhood experiences (ACEs) involved specific questionnaire items. Genetic variants were identified via RT-PCR. Statistical analysis employed linear multivariate regression, while mediation analysis examined gene-environment interactions. RESULTS: In the pre-pandemic, higher PTSS scores were found to be associated with younger age (p = 0.02) and a history of cumulative ACEs (p = 0.001). Mediation analysis revealed that ACEs had a direct impact on PTSS scores, with the FKBP5 CC genotype (rs1360780, C>T) mediating this association by 29%. In the pandemic, elevated PTSS scores were correlated with a history of depression (p = 0.001), the negative impact of the pandemic (p = 0.007), and undergoing palliative treatment (p = 0.02). CONCLUSIONS: Our findings provide insights into the psychosocial and genetic factors contributing to PTSS in HNC patients, considering the additional stressors introduced by the COVID-19 pandemic.
