Background: Salivary gland cancers (SGC)‐social determinants of health (SDoH) investigations are limited by narrow scopes of SGC‐types and SDoH. This Social Vulnerability Index (SVI)‐study hypothesized that socioeconomic status (SES) most contributed to SDoH‐associated SGC‐disparities. Methods: Retrospective cohort of 24 775 SGCs assessed SES, minority‐language status (ML), household composition (HH), housing‐transportation (HT), and composite‐SDoH measured by the SVI via regressions with surveillance and survival length, late‐staging presentation, and treatment (surgery, radio‐, chemotherapy) receipt. Results: Increasing social vulnerability showed decreases in surveillance/survival; increased odds of advanced‐presenting‐stage (OR: 1.12, 95% CI: 1.07, 1.17), chemotherapy receipt (OR: 1.13, 95% CI: 1.03, 1.23); decreased odds of primary surgery (0.89, 0.84, 0.94), radiotherapy (0.91, 0.85, 0.97, p = 0.003) for SGCs. Trends were differentially correlated with SES, ML, HH, and HT‐vulnerabilities. Conclusions: Through quantifying SDoH‐derived SGC‐disparities, the SVI can guide targeted initiatives against SDoH that elicit the most detrimental associations for specific sociodemographics.

Key point: Social determinants of health interactively influence sinonasal cancer care and prognosis.Housing‐transportation and socioeconomic status showed the largest associations with disparities.The social vulnerability index can reveal the social determinants of sinonasal cancers.

Objective: To investigate the association of social determinants of health (SDoH) in squamous cell carcinoma of the tongue in the United States and to evaluate the real‐world contribution of specific disparities. Study Design: Retrospective cohort study. Setting: United States. Methods: The Centers for Disease Control and Prevention‐Social Vulnerability Index (SVI) and National Cancer Institute‐Surveillance, Epidemiology, and End Results Program database were used to study 62,103 adult tongue squamous cell carcinoma patients from 1975 to 2017. Regression analysis assessed trends in months of follow‐up and survival across social vulnerability and 4 subcategories of social vulnerability. Results: As overall SVI score increases (increased social vulnerability), there is a significant decrease in the average length of follow‐up (22.95% decrease from 63.99 to 49.31 months; P <.001) across patients from the lowest and highest social vulnerability groups. As overall SVI score increases, there is a significant decrease in the average months of survival (28.00% decrease from 49.20 to 35.43 months; P <.001). There is also a significantly greater odds ratio (OR = 1.05; P <.001) of advanced cancer staging upon presentation at higher SVI scores. Patients with higher SVI scores have a lower OR (0.93; P <.001) of receiving surgery as their primary treatment when compared to patients with lower SVI scores. Patients with higher SVI scores also have a significantly greater OR (OR = 1.05; P <.001) of receiving chemotherapy as their primary treatment when compared to patients with lower SVI scores. Conclusion: Increased social vulnerability is shown to have a detrimental impact on the treatment and prognosis of patients with squamous cell carcinoma of the tongue. [ABSTRACT FROM AUTHOR]

Objective: To compare head and neck squamous cell carcinoma stage at presentation and survival in Medicaid‐expanded states versus nonexpanded states. Study Design: Retrospective cohort. Setting: Northwestern University Feinberg School of Medicine. Methods: The Head and Neck with human papillomavirus Status Database within the Surveillance, Epidemiology, and End Results (SEER) Program was queried for cases of head and neck squamous cell carcinoma (HNSCC) diagnosed in the years 2010 to 2016. Cases were grouped according to their respective state Medicaid expansion status. Multivariable logistic regressions and multivariable Cox proportional hazards models were used to evaluate associations with stage IV disease and survival. Results: Compared to nonexpanded states, Medicaid‐expanded states had a significantly larger proportion of Medicaid patients (20.3% vs 16.7%, P =.0009) and a significantly smaller proportion of uninsured patients (1.7% vs 10.1%, P <.0001). The case selection process resulted in 2215 patients meeting inclusion criteria. In multivariable analysis, cases under Medicaid expansion were 31% less likely to present with stage IV disease compared to cases in nonexpanded states (odds ratio: 0.69, 95% confidence interval [CI]: 0.51‐0.93). In the multivariable Cox proportional hazards model, cases under Medicaid expansion had significantly better mortality outcomes and were 32% less likely to die compared to cases in nonexpanded states (hazard ratio: 0.68, 95% CI: 0.55‐0.84). Conclusion: Medicaid expansion is associated with fewer stage IV cases and improved survival of HNSCC cases. These findings support continued efforts to expand Medicaid coverage.

Introduction: Technology and internet access have become increasingly integrated into healthcare as the primary platform for health-related information and provider-patient communication. Disparities in access to digital resources exist in the United States and have been shown to impact health outcomes in various head and neck malignancies. Our objective is to evaluate the associations of digital inequity on health outcomes in patients with salivary gland cancer (SGC)., Methods: The Digital Inequity Index (DII) was developed using 17 census-tract level variables obtained from the American Community Survey and Federal Communications Commission. Variables were categorized as digital infrastructure or sociodemographic (e.g., non-digital) and scored based on relative rankings across all US counties. Scores were assigned to patients from the Surveillance-Epidemiology-End Results (SEER) database diagnosed with SGC between 2013 and 2017 based on county-of-residence. Regressions were performed between DII score and outcomes of surveillance time, survival time, tumor stage at time of diagnosis, and treatment modality., Results: Among 9306 SGC-patients, increased digital inequity was associated with advanced-staging at presentation (OR: 1.04, 95% CI: 1.01-1.07, p = 0.033), increased odds of chemotherapy receipt (OR: 1.05, CI: 1.01-1.10, p = 0.010), and decreased odds of surgical intervention (OR: 0.94, 95% CI: 0.91-0.98, p = 0.003) after accounting for traditional sociodemographic factors. Increased digital inequity was also associated with decreased surveillance time and survival periods., Conclusions: Digital inequity significantly and independently associates with negative health and treatment outcomes in SGC patients, highlighting the importance of directed efforts to address these seldom-investigated drivers of health disparities., (© 2024 The Author(s).
