This study investigated the association between HPV tumor status and suicide risk among patients with head and neck cancer. The results showed that HPV-positive cancers had a slightly higher risk of suicide compared to HPV-negative cancers, but this association was no longer significant in the fully adjusted model. However, the relationship between HPV status and suicide risk in oropharyngeal cancer patients remains uncertain due to the wide confidence interval.
Importance Human papillomavirus (HPV) is strongly associated with head and neck cancer, and HPV status is considered a prognostic factor. Being a sexually transmitted infection, HPV-related cancers may have greater risk of stigma and psychological distress; however, the potential association of HPV-positive status with psychosocial outcomes, such as suicide, is understudied in head and neck cancer.Objective To investigate the association between HPV tumor status and suicide risk among patients with head and neck cancer.Design, Setting, and ParticipantsThis population-based retrospective cohort study included adult patients with clinically confirmed cases of head and neck cancer based on HPV tumor status from the Surveillance, Epidemiology, and End Results database from January 1, 2000, to December 31, 2018. Data analysis was conducted from February 1 to July 22, 2022.Main Outcomes and Measures The outcome of interest was death by suicide. Primary measure was HPV status of tumor site, dichotomized as positive or negative. Covariates included age, race, ethnicity, marital status, cancer stage at presentation, treatment modality, and type of residence. Cumulative risk of suicide among patients with HPV-positive and HPV-negative head and neck cancer was assessed using Fine and Gray competing risk models.Results Of 60 361 participants, the mean (SD) age was 61.2 (13.65) years, and 17 036 (28.2%) were women; there were 347 (0.6%) American Indian, 4369 (7.2%) Asian, 5226 (8.7%) Black, 414 (0.7%) Native Hawaiian or Other Pacific Islander, and 49 187 (81.5%) White individuals. A competing risk analysis showed a significant difference in the cumulative incidence of suicide between HPV-positive cancers (5-year suicide-specific mortality, 0.43%; 95% CI, 0.33%-0.55%) and HPV-negative cancers (5-year suicide-specific mortality, 0.24%; 95% CI, 0.19%-0.29%). Tumor status that was HPV positive was associated with increased suicide risk in the unadjusted model (hazard ratio [HR], 1.76; 95% CI, 1.28-2.40), but not the fully adjusted model (adjusted HR, 1.18; 95% CI, 0.79-1.79). Among people with oropharyngeal cancer only, HPV status was associated with increased suicide risk, but the width of the confidence interval prevented definitive conclusion (adjusted HR, 1.61; 95% CI 0.88-2.94).Conclusions and Relevance The results of this cohort study suggest that patients with HPV-positive head and neck cancer have similar risk of suicide as patients with HPV-negative cancer, despite differences in overall prognosis. Early mental health interventions may be associated with reduced suicide risk in all patients with head and neck cancer and should be assessed in future work.
