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.

Objective: Indications for adjuvant radiation in pediatric salivary gland carcinoma rely on high-risk criteria extrapolated from adult data. We sought to determine whether adult-derived high-risk criteria were prognostic in children aged ≤21 years or young adults aged 22 to 39 years. Study Design: Cross-sectional analysis of a hospital-based national registry. Setting: Patients were identified from the National Cancer Database between 2004 and 2015. Methods: High-risk criteria were defined as adenoid cystic histology, intermediate/high grade, T3/T4, positive margins, and/or lymph node involvement. Exact matching was used to adjust for differences in baseline characteristics between pediatric and young adult patients. Results: We identified 215 pediatric patients aged ≤21 years, 317 patients aged 22 to 30 years, and 466 patients aged 31 to 39 years. Within the pediatric cohort, there was no significant difference in overall survival (OS) between low- and high-risk groups (5-year OS, 100% vs 98.5%; P =.29). In contrast, within the young adult cohorts, there was a significant difference in OS between low- and high-risk groups in patients aged 22 to 30 years (5-year OS, 100% vs 96.1%; P =.01) and 31 to 39 years (5-year OS, 100% vs 88.5%; P <.001). When high-risk patients were matched 1:1 on high-risk criteria and race, pediatric patients were associated with better OS than those aged 22 to 30 years (P =.044) and those aged 31 to 39 years (P =.005). Conclusion: Children have excellent OS, irrespective of adult-derived high-risk status. These findings underscore the need to understand how age modifies clinicopathologic risk factors.

Objective: To evaluate factors associated with overall survival (OS) of patients with non-rhabdomyosarcoma soft tissue sarcomas of the head and neck.Study Design: Retrospective cohort study.Methods: The National Cancer Database was queried for cases of non-rhabdomyosarcoma soft tissue sarcomas of the head and neck between 2004 and 2014. Cases were categorized according to the World Health Organization classification of soft tissue tumors. A multivariable Cox proportional hazards model was used to evaluate associations with OS.Results: A total of 4,555 patients (63.6% male, 36.4% female, mean age 59.6 years) met inclusion criteria. The majority of tumors were classified as miscellaneous (35.9%), followed by vascular (20.1%), smooth muscle (13.5%), fibroblastic/myofibroblastic (12.1%), peripheral nerve (8.5%), adipocytic (7.4%), and undifferentiated (2.5%) sarcomas. The mean follow-up was 37.9 months, and overall mortality (MR) was 45.3%. The best prognosis was seen with fibroblastic/myofibroblastic sarcomas (MR = 20.6%, P < .001), whereas vascular sarcomas had the worst prognosis (MR = 67.6%, P < .001). Resection with clear margins had better OS than microscopically positive margins (hazard ratio [HR] = 1.43, P < .001) or grossly positive margins (HR = 2.97, P < .001). Radiation therapy was associated with better OS than no radiation (HR = 0.86, P = .001).Conclusion: Non-rhabdomyosarcoma soft tissue sarcomas of the head and neck are associated with significant mortality. OS differs based on histologic subcategorization. Resection of the primary tumor with clear margins demonstrates improved OS for all histologies, suggesting this modality remains the preferred primary treatment when feasible.Level Of Evidence: 3 Laryngoscope, 131:E500-E508, 2021.
