RESUMEN
T follicular helper (TFH) cells are crucial for B cell-mediated humoral immunity1. Although transcription factors such as BCL6 drive the differentiation of TFH cells2,3, it is unclear whether and how post-transcriptional and metabolic programs enforce TFH cell programming. Here we show that the cytidine diphosphate (CDP)-ethanolamine pathway co-ordinates the expression and localization of CXCR5 with the responses of TFH cells and humoral immunity. Using in vivo CRISPR-Cas9 screening and functional validation in mice, we identify ETNK1, PCYT2, and SELENOI-enzymes in the CDP-ethanolamine pathway for de novo synthesis of phosphatidylethanolamine (PE)-as selective post-transcriptional regulators of TFH cell differentiation that act by promoting the surface expression and functional effects of CXCR5. TFH cells exhibit unique lipid metabolic programs and PE is distributed to the outer layer of the plasma membrane, where it colocalizes with CXCR5. De novo synthesis of PE through the CDP-ethanolamine pathway co-ordinates these events to prevent the internalization and degradation of CXCR5. Genetic deletion of Pcyt2, but not of Pcyt1a (which mediates the CDP-choline pathway), in activated T cells impairs the differentiation of TFH cells, and this is associated with reduced humoral immune responses. Surface levels of PE and CXCR5 expression on B cells also depend on Pcyt2. Our results reveal that phospholipid metabolism orchestrates post-transcriptional mechanisms for TFH cell differentiation and humoral immunity, highlighting the metabolic control of context-dependent immune signalling and effector programs.

OBJECTIVES: This study aims to analyze the behavior and treatment of adenoid cystic carcinoma (AdCC) in the pediatric and young adult population and to identify factors affecting overall survival (OS). MATERIALS AND METHODS: The study analyzed salivary gland malignancies in patients aged 0-21 with AdCC histology using the National Cancer Database from 2004 to 2018. RESULTS: A total of 72 patients (59.7% parotid, 36.1% submandibular, 1.4% sublingual, 2.8% unspecified) met criteria. Median age was 18 years [range: 0-21]. High-grade dysplasia was present in 67% of cases. Therapy consisted of primary surgery for all cases, regional lymph node dissection (LND) (74%), radiotherapy (71%), chemotherapy (8%), and chemoradiation (7%). The 5-year OS rate was 93.2% [95% confidence interval (CI): 86.9%-99.9%], respectively. Patients who underwent associated LND had improved OS (p = .0083, log-rank test) with a 5-year OS at 82.4% [95% CI: 66.1%-100%] versus 97.6% [95% CI: 93.0%-100%]. A significant difference in OS was found with unfavorable outcomes after positive marginal status: 5-year OS 84.1% [95% CI: 71.0%-99.7%] versus 100% [95% CI: 100%]; p < .001. Adjuvant therapy did not seem to impact the outcome. CONCLUSION: This study confirms that AdCC in children and young adults has an overall good prognosis despite frequent high grade. It suggests that cervical LND may be of importance, but the value of systematic adjuvant therapy is not confirmed. These findings emphasize the importance and relevance of population-based studies in shaping clinical practice and informing the design of future prospective investigations.

OBJECTIVES: To develop and implement a novel, comprehensive tool, the Digital Inequity Index (DII), that quantifiably measures modern-technology access in the US to assess the impact of digital inequity on laryngeal cancer (LC) care nationwide. METHODS: DII was calculated based on 17 census-tract level variables derived from the American Community Survey and Federal Communications Commission. Variables were categorized as infrastructure-access (i.e., electronic device ownership, type of broadband, internet provider availability, income-broadband subscription ratio) or sociodemographic (i.e., education, income, disability status), ranked and then averaged into a composite score. 22,850 patients from 2008 to 2017 in SEER were assessed for regression trends in long-term follow-up, survival, prognosis, and treatment across increasing overall digital inequity, as measured by the DII. This methodology allows for us to assess the independent contribution of digital inequity adjusted for socioeconomic confounders. RESULTS: With increasing overall digital inequity, length of long-term follow-up (p < 0.001) and survival (p = 0.025) decreased. Compared to LC patients with low DII, high DII was associated with increased odds of advanced preliminary staging (OR 1.06; 95 % CI 1.03-1.08), treatment with chemotherapy (OR 1.06; 95 % CI 1.04-1.08), and radiation therapy (OR 1.02; 95 % CI 1.00-1.04), as well as decreased odds of surgical resection (OR 0.96; 95 % CI 0.94-97). CONCLUSIONS: Digital inequities are associated with detrimental trends in LC patient outcomes in the US, allowing discourse for targeted means of alleviating disparities while contextualizing national sociodemographic trends of the impact of online access on informed care.

BACKGROUND: High-intensity focused ultrasound (HIFU) is a less invasive option offered for the treatment of large, compressive, benign thyroid nodules. METHODS: Observational studies of more than five participants using HIFU in the management of benign thyroid nodules from 2000 to 2021 were identified using predefined inclusion criteria. The primary outcome was an estimate of the effectiveness of HIFU. RESULTS: Out of 158 studies reviewed, 8 articles were included with 297 patients and 300 nodules. HIFU significantly reduced nodule volume from 1 to 24 months following therapy (weighted mean difference [WMD], 47.68, 95 % confidence interval [CI], 34.13-59.66, p < 0.0001) and achieved favorable success rates (risk ratio [RR], 1.49, 95 % CI, 1.15-1.84, p < 0.001) for 50 % volume reduction. CONCLUSIONS: HIFU appears to be a feasible, safe, and effective treatment modality for patients with benign thyroid nodules. Future research, including randomized controlled trials, is needed to determine therapy optimization, and patient selection to identify the potential role of this new therapy.

BACKGROUND: Data on primary hypothyroidism and its long-term impact on the health, cognition, and quality of life (QOL) of childhood cancer survivors are limited. This study examined the prevalence of and risk factors for primary hypothyroidism and its associations with physical, neurocognitive, and psychosocial outcomes. METHODS: This was a retrospective study with a cross-sectional health outcome analysis of an established cohort comprising 2965 survivors of childhood cancer (52.8% male; median current age, 30.9 years, median time since cancer diagnosis, 22.3 years). Multivariable logistic regression estimated odds ratios (ORs) and 95% confidence intervals (CIs) for associations between primary hypothyroidism and cancer-related risk factors, cardiovascular disease risk factors, frailty, neurocognitive and QOL outcomes, social attainment, and subsequent thyroid carcinoma. Associations between serum free thyroxine and thyrotropin levels at assessment and health outcomes were explored. RESULTS: The prevalence of primary hypothyroidism was 14.7% (95% CI, 13.5%-16.0%). It was more likely in females (OR, 1.06; 95% CI, 1.03-1.08), was less likely in non-Whites (OR, 0.96; 95% CI, 0.93-0.99), was associated with thyroid radiotherapy (higher risk at higher doses), and was more common if cancer was diagnosed at an age ≥ 15.0 years versus an age < 5 years (OR, 1.05; 95% CI, 1.01-1.09). Primary hypothyroidism was associated with frailty (OR, 1.54; 95% CI, 1.05-2.26), dyslipidemia (OR, 1.52; 95% CI, 1.14-2.04), impaired physical QOL (OR, 1.66; 95% CI, 1.12-2.48), and having health care insurance (OR, 1.51; 95% CI, 1.07-2.12). CONCLUSIONS: Primary hypothyroidism is common in survivors and is associated with unfavorable physical health and QOL outcomes. The impact of thyroid hormone replacement practices on these outcomes should be investigated further.

The International Soft Tissue Sarcoma Database Consortium (INSTRuCT) consists of a collaboration between the Children's Oncology Group (COG) Soft Tissue Sarcoma Committee, the European pediatric Soft Tissue Sarcoma Study Group (EpSSG), and the Cooperative Weichteilsarkom Studiengruppe (CWS). As part of the larger initiative of INSTRuCT to provide consensus expert opinions for clinical treatment of pediatric soft tissue sarcoma, we sought to provide updated, evidenced-based consensus guidelines for local treatment of parameningeal rhabdomyosarcoma using both existing literature as well as recommendations from the relevant cooperative group clinical trials. Overall, parameningeal rhabdomyosarcoma represents a distinctly challenging disease to treat, given its location near many critical structures in the head and neck, frequently advanced local presentation, and predilection for local failure. Definitive chemoradiation remains the standard treatment approach for parameningeal rhabdomyosarcoma, with surgery often limited to biopsy or salvage therapy for recurrent disease. In this consensus paper, we specifically discuss consensus guidelines and evidence for definitive local management with radiotherapy, with a focus on imaging for radiotherapy planning, dose and timing of radiation, approach for nodal irradiation, various radiation techniques, including proton therapy, and the limited role of surgical resection.

ABSTRACT: Historically, the accuracy of imaging teeth by computed tomography (CT) has been suboptimal and deemed inadequate for surgical planning of orthognathic procedures. However, recent advances in CT hardware and software have significantly improved the accuracy of imaging occlusal anatomy. This technical note describes a quantitative means of evaluating the accuracy of CT-based modeling of teeth. Three-dimensional models of the dentition were created from a CT scan obtained of a craniomaxillofacial skeleton. Multiple reconstruction algorithms and modeling parameters were applied. The dentition of the same skeleton was scanned using a handheld optical scanning device to serve as the "gold standard." Semi-automated registrations of CT and optically acquired models were performed and deviation analysis was conducted. On average, the deviation of the CT model with the optical scan measured 0.19 to 0.25 mm across the various reconstruction and modeling parameters, with a mean of 0.22 mm. Computed tomography underestimated contours at cusp tips, while overestimating contours in occlusal groves. The use of bone reconstruction algorithms and decreased model smoothing resulted in more accurate models, though greater surface noise. Future studies evaluating the clinical effectiveness of CT-based occlusal splints should take this finding into account.

OBJECTIVE: To investigate the impact of neighborhood-level social vulnerability on pediatric tonsillectomy outcomes. METHODS: This single-center retrospective cohort study included tonsillectomies performed on children aged 1 to 18 between August 2019 and August 2020. Geographic information systems were used to geocode addresses, and spatial overlays were used to assign census-tract level social vulnerability index (SVI) scores to each patient. For categorical variables, two-sided Pearson chi-square tests were used, whereas for continuous variables, paired t-tests, means, and standard deviations were calculated. SVI and its four subthemes were investigated using binomial logistic regressions to determine their impact on post-T&A complications and readmissions. RESULTS: The study included 397 patients, with 52 having complications (13.1%) and 33 (8.3%) requiring readmissions due to their complications. Controlling for age, gender, race, insurance status, surgical indication, comorbidities, obesity, and obstructive sleep apnea, postoperative complications were associated with high overall SVI (odds ratio [OR] 5.086, 95% confidence interval [CI] 1.128-22.938), high socioeconomic vulnerability (SVI theme 1, OR 6.003, 95% CI 1.270-28.385), and high house composition vulnerability (SVI theme 2, OR 6.340, 95% CI 1.275-31.525). Readmissions were also associated with high overall SVI (10.149, 95% CI 1.293-79.647) and high housing/transportation vulnerability (SVI theme 4, OR 5.657, 95% CI 1.089-29.396). CONCLUSION: Social vulnerability at the neighborhood level is linked to poorer surgical outcomes in otherwise healthy children, suggesting a target for community-based interventions. Because of the increased risk, it may have implications for preoperative decision-making, treatment plans, and clinic follow-ups. LEVEL OF EVIDENCE: 3: Laryngoscope, 134:954-962, 2024.

OBJECTIVES: Studies addressing social determinants of health (SDH) in head-neck melanomas (HNM) have only assessed incidence with increasing socioeconomic status. None have investigated a wider scope of SDH or their summed influence on affecting HNM prognosis and follow-up care. METHODS: This retrospective cohort study analyzed 374,138 HNM in adults from 1975 to 2017 from the NCI-Surveillance, Epidemiology, and End Results Program (NCI-SEER) database. Utilizing the NCI-SEER database, Social Vulnerability Index (SVI) scores were matched to county of residence upon diagnosis. Univariate linear regressions were performed on length of care (months of follow-up/surveyed) and prognosis (months survival) across various SDH/SVI scores of socioeconomic status, minority and language status, household composition, housing and transportation, and their total composite. RESULTS: With increasing overall SVI score, which indicates increasing social vulnerability, months of follow-up showed significant decreases ranging from 0.04% to 27.63% compared with the lowest vulnerability groups, with the highest differences in nodular melanomas and the lowest with malignant melanomas in giant pigmented nevi. Similarly, months survival significant decreases ranged from 0.19% to 39.84% compared with the lowest SVI scores, with the highest difference in epithelioid cell melanomas and the lowest in amelanotic melanoma. Comprising this overall score trend, decreases with socioeconomic status, minority-language status, household composition, and housing-transportation contributed differentially per histology subtype. CONCLUSIONS: Our data highlight significant negative trends in HNM prognosis and care with higher total social vulnerability while showing which SDH-themes quantifiably contribute more to these differences. LEVEL OF EVIDENCE: 3 Laryngoscope, 134:185-190, 2024.

OBJECTIVE: To investigate the utility of answers generated by ChatGPT, a large language model, to common questions parents have for their children following tonsillectomy. METHODS: Twenty Otolaryngology residents anonymously submitted common questions asked by parents of pediatric patients following tonsillectomy. After identifying the 16 most common questions via consensus-based approach, we asked ChatGPT to generate responses to these queries. Satisfaction with the AI-generated answers was rated from 1 (Worst) to 5 (Best) by an expert panel of 3 pediatric Otolaryngologists. RESULTS: The distribution of questions across the five most common domains, their mean satisfaction scores, and their Krippendorf's interrater reliability coefficient were: Pain management [6, (3.67), (0.434)], Complications [4, (3.58), (-0.267)], Diet [3, (4.33), (-0.357)], Physical Activity [2, (4.33), (-0.318)], and Follow-up [1, (2.67), (-0.250)]. The panel noted that answers for diet, bleeding complications, and return to school were thorough. Pain management and follow-up recommendations were inaccurate, including a recommendation to prescribe codeine to children despite a black-box warning, and a suggested post-operative follow-up at 1 week, rather than the customary 2-4 weeks for our panel. CONCLUSION: Although ChatGPT can provide accurate answers for common patient questions following tonsillectomy, it sometimes provides eloquently written inaccurate information. This may lead to patients using AI-generated medical advice contrary to physician advice. The inaccuracy in pain management answers likely reflects regional practice variability. If trained appropriately, ChatGPT could be an excellent resource for Otolaryngologists and patients to answer questions in the postoperative period. Future research should investigate if Otolaryngologist-trained models can increase the accuracy of responses.

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.

Background: As thyroid cancer incidence rises, it is increasingly valuable to recognize disparities in treatment and diagnosis. Prior investigations into social determinants of health (SDoH) are limited to pediatric populations or studies looking at single factors such as race or environmental influences. Utilizing the CDC-social vulnerability index and SEER-patient database to assess the amalgamated, real-world influence of varied SDoH and their quantifiable impact on thyroid cancer disparities across the United States. Methods: In a retrospective cohort study, 199,340 adult thyroid cancer patients from 1975 to 2017 were assessed for significant regression trends in months of follow-up/surveillance, survival, late staging, and treatment receipt across thyroid cancer-subtypes with increasing overall social vulnerability, as well as in 15 SDoH variables regarding socioeconomic status, minority-language status, household composition, and housing-transportation across all the U.S. counties while accounting for sociodemographic regional differences. Results: With increasing overall social vulnerability, decreases in months of follow-up were observed with patients with papillary, follicular, medullary, oncocytic, and anaplastic thyroid cancer (p = 0.001). Comparing lowest with highest vulnerability cohorts, relative decreases in months of surveillance ranged from 55.6% (14.5-6.5 months) with anaplastic to 17% (108.6-90.2) with oncocytic. Socioeconomic status vulnerabilities, followed by vulnerabilities in household composition and housing-transportation type, contributed to these overall trends. Similar survival decreases occurred across all thyroid cancer patients, ranging from 55.9% (9.6-4.2) with anaplastic to 28.3% (97-69.5) with oncocytic. Minority-language status vulnerabilities and housing-transportation types largely contributed to these trends. Increasing overall vulnerability was associated with increased odds of advanced staging for papillary (odds ratio [OR] = 1.07 [confidence interval, CI 1.03-1.12]) and decreased odds of indicated treatment via surgery (lowest, medullary: 0.91 [CI 0.84-0.99]), radiation therapy (lowest, anaplastic: 0.88 [CI 0.82-0.93]), and chemotherapy (lowest, oncocytic: 0.81 [CI 0.67-0.98]) were observed. Vulnerabilities in minority-language status and housing-transportation, followed by socioeconomic status vulnerabilities, were differential contributors to these overall vulnerability trends. Conclusions: Our results show significant detriments in thyroid cancer care and prognosis in the United States with increasing overall social vulnerability while identifying which SDoH quantifiably contribute more to disparities in inter-relational, real-world-like contexts.

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.

INTRODUCTION: Developmental delay (DD) affects one in six children and has been shown to require more health care than the average child [1-2]. Certain recent studies have suggested an increased rate of complications/costs in children with DD [3-5]. Our objective was to perform a retrospective study comparing DD children to non-DD controls in patients presenting for tonsillectomy over a 1-year period to further define the relationship between DD and post-operative complications. METHODS: We conducted a retrospective chart review of children undergoing tonsillectomy over a one-year period. We collected demographic information, polysomnogram, comorbidities, complications, and length of stay. A diagnosis of developmental delay was considered if recorded prior to the tonsillectomy or workup was ongoing at the time of tonsillectomy. All data was analyzed using IBM SPSS Statistics 25. RESULTS: The final cohort included 400 patients. Our cohort had 56 patients with diagnosis of DD. We recorded 18 complications in the DD population (32.14%) compared to 30 complications in the control group (8.72%) (p < 0.00001). Children with DD had higher incidence of comorbidities (p < 0.00001), complication with comorbidities (p < 0.00001), and incidence of prematurity (p < 0.00001); whereas, they did not have increased length of stay (LOS) (p = 0.33) or complications if premature (p = 0.22). Pre-operative polysomnogram was associated with higher incidence of complication (p = 0.035) in the total population but children with DD did not have higher pre-operative obstructive apnea-hypopnea index (oAHI)compared to the control patients (p = 0.25). CONCLUSION: Children with DD were found to have a significantly higher complication rate compared to children without DD in our patient population. They did have higher incidence of additional comorbidities and prematurity. This elevated risk should at least be included in pre-operative counseling, but additionally has potential implications for pre-operative decision making and treatment plans in this high-risk population.

OBJECTIVE: To review otology-related studies using the US Food and Drug Administration's Manufacturer and User Facility Device Experience (MAUDE) database to identify the opportunities and limitations of using MAUDE. DATABASES REVIEWED: PubMed, Science Direct, Web of Science, SCOPUS, and EMBASE. METHODS: All studies reporting otology-related adverse events extracted from MAUDE were included from June 20, 2002, to 2022. Two reviewers independently screened abstracts, selected articles for exclusion, extracted data, and appraised studies. Critical appraisal was done according to the National Institutes of Health quality assessment tool for case series. RESULTS: The search yielded 5,645 studies, of which 8 studies met the inclusion criteria. All eight studies were case series; three evaluated cochlear implants, two evaluated osseointegrated hearing implants, and one evaluated illuminated operating microscope use. Quality assessment revealed all studies to be of poor quality. The most common domains contributing to these ratings included unclear study population, lack of consecutive participants, comparability of participants, clear and consistent outcome measures, and appropriate statistical analysis. CONCLUSION: Otology studies using the MAUDE database are of poor quality. This was primarily due to MAUDE's structural limitations as a passive surveillance system using nonstandardized free-text reports. The quality of studies also suffered from inappropriate analysis of MAUDE data, given its design. The utility of MAUDE could be improved by implementing case report best practices and converting the free fields to allow controlled and adaptive responses wherever possible to help standardize adverse event reporting.

OBJECTIVE: Head and neck cancers represent critical challenges due to the restricted anatomical space in children and the proximity of critical neurovascular structures which can compromise complete tumor resection. Applications of Indocyanine green (ICG) near infrared (NIR) fluorescent image-guided surgery (FGS) have recently expanded into the pediatric population, emphasizing its relevance for tumor delineation and evaluation of tissue perfusion. The objectives of the present study are twofold. First, we aim to assess the role of ICG NIR imagery in identifying neoplastic disease and second, to evaluate its role as an adjunct to identify metastatic deposits in cervical lymph node in children, adolescents, and young adults with head and neck cancers. METHODS: Eight patients with head and neck malignancies underwent ICG NIR FGS, between January 2019 and November 2021. ICG NIR findings were compared with preoperative cross-sectional imaging and results of operative tissue pathology analyses. RESULTS: All primary tumors were identified on preoperative imaging and intraoperatively with ICG NIR; however, for one case, extension of tumor was revealed with ICG NIR and confirmed by histopathological examination but was not otherwise visible on preoperative imaging or with naked eye visual and tactile assessment. ICG NIR assisted the decision process in a difficult case for which curative resection, without significant functional morbidity and potential mortality, was unrealistic. Although ICG NIR evaluation of the surgical bed did not display residual tumor, margins were found positive in two cases. ICG NIR evaluation for local metastases changed the surgical strategy in one patient by prompting conversion to bilateral neck dissections. The sensitivity of preoperative multimodality imaging to identify cervical levels of invasion was 75% with a specificity of 70%, a PPV of 33%, a NPV of 78% and an accuracy of 72%. The ICG NIR sensitivity was 83%, its specificity was 88% with a PPV of 91%, a NPV of 80% and an accuracy of 86%. The combination of preoperative multimodality imaging with ICG NIR findings led to a sensitivity of 83%, specificity of 88% and accuracy of 86%. CONCLUSION: This case series provides a proof of concept of the feasibility of ICG NIR, as an adjunct in tumor and local metastases identification in young patients with head and neck tumors. It revealed to be feasible and safe for intra-operative tumor identification, thus guiding and facilitating resection. However, it showed some limitations in precise tumor margin assessment. The combination of preoperative multimodality imaging with ICG NIR findings improved local metastases localization.

PURPOSE OF REVIEW: Prior investigations in social determinants of health (SDoH) and their impact on pediatric head and neck cancers are limited by the narrow scope of cancer types and SDoH being studied while lacking inquiry on the interrelational contribution of varied SDoH in real-world contexts. The purpose of this review is to discuss the current research tackling these shortcomings of SDoH-based studies in head and neck cancer and to discuss means of applying these findings in prospective initiatives and implementations. RECENT FINDINGS: Through leveraging contemporary, large-data analyses measuring diverse social vulnerabilities, several studies have identified comprehensive delineations of which social disparities contribute the largest quantifiable impact on the care of head and neck cancer patients. Progressing from prior SDoH-based research of the decade, these studies contextualize the effect of social vulnerabilities and have laid the foundations to begin addressing these issues in the complex, modern-day environment of interrelatedsocial factors. SUMMARY: Social determinants of health markedly affect pediatric head and neck cancer care and prognosis in complex and surprising ways. Modern-day tools and analyses derived from large-data techniques have unveiled the quantifiable underpinnings of how SDoH impact these pathologies.
