Disparities in pediatric parotid cancer treatment and presentation: A National study

Objectives: Although parotid gland malignancies are uncommon, they nevertheless represent a cause of morbidity and mortality in the pediatric population. Few studies have sought to identify disparities related to their presentation, treatment, and survival. There is a need to understand these variations to improve care for historically underrepresented groups. Study design: Retrospective Cohort Study. Setting: Surveillance, Epidemiology, and End Results (SEER) Program Database. Methods: Analysis of pediatric patients with parotid gland malignancies between 2000 and 2019. Race and ethnicity were classified as Non-Hispanic White, Non-Hispanic Black, Asian, and Hispanic for multivariable analysis. Outcomes included tumor size and stage at diagnosis, survival, and need for facial nerve sacrifice. Kaplan-Meier analysis was used to analyze survival. Multivariable logistic regression was conducted to identify predictors of outcomes. Results: 149 patients met the criteria for inclusion. Stratified by race/ethnicity, Non-Hispanic Black (Median 23 mm, IQR 15-33), Asian (30 mm, 14-32), and Hispanic (23 mm, 20-28) patients had larger tumors at presentation than Non-Hispanic White patients (18 mm, 12-25, p = 0.017). Disease-specific survival differed by timeto-treatment (log-rank, p = 0.01) and overall survival differed by income (p < 0.001). On multivariable analysis, Hispanic patients were more likely to experience facial nerve sacrifice (OR 3.71, 95%CI 1.25-11.6, p = 0.020), and Non-Hispanic Black (OR 3.37, 0.95-11.6, = 0.053) and Asian (OR 5.67, 1.46-22.2, p = 0.011) patients presented with larger tumors compared to Non-Hispanic White patients. Conclusions: Variations in presentation and treatment exist across race and ethnicity in pediatric parotid cancer. Identifying these disparities may help improve access and outcomes for underserved patient populations. Level of evidence: III.
