Pediatric Robotic Laryngeal Cleft Repair.

OBJECTIVE: Compare surgical and swallow outcomes in robotic versus traditional laryngeal cleft (LC) repairs. STUDY DESIGN: Retrospective cohort study. SETTING: Tertiary care pediatric hospital. METHODS: Pediatric patients who underwent robotic or traditional (open or endoscopic) LC repair between 2010 and 2021 were identified. Patient characteristics, operative times, adverse events, hospital length of stay (LOS), and modified barium swallow study (MBSS) results were compared. RESULTS: Eighteen robotic and thirty traditional LC repairs were identified. Mean surgical (149 vs 111 min, P < .05) and OR times (207 vs 139 min, P < .002) were increased for robotic type I LC repairs, but were similar for type II and III LC. Mean hospital LOS was increased for robotic type I LC repairs (2.6 vs 1.2 days, P < .006), but was decreased for type II (4 vs 12.2 days) and type III (4.3 vs 94.5 days) LC. Postoperative MBSS results were improved for robotic type I LC repairs at 12 months (82% vs 43%, P = .05), and trended toward improvement at 6 months for type II (75% vs 22%), and type III (67% vs 50%) LC repairs, although significance was limited for type II and III LC due to the number of subjects. A robotic approach was used successfully to revise all recurrent LC that failed traditional repairs. CONCLUSION: Robotic type 1 LC repairs demonstrated increased operative times and hospital LOS but improved postoperative swallow outcomes compared to traditional approaches may be particularly useful in cases of recurrent clefts.

The Toxicological Effects of e-Cigarette Use in the Upper Airway: A Scoping Review.

OBJECTIVE: While evidence continues to emerge on the negative health effects of electronic cigarettes (e-cigarettes) on the lungs, little is known regarding their deleterious effects on the upper airway. The purpose of this review is to summarize the toxicological effects of e-cigarettes, and their components, on the upper airway. DATA SOURCES: PubMed, SCOPUS, EMBASE databases. REVIEW METHODS: Systematic searches were performed in accordance with Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines from 2003 to 2023. Studies were included if they investigated the toxicological effects of e-cigarette exposure on human or animal upper airway tissue. Two authors independently screened, reviewed, and appraised all included articles. RESULTS: A total of 822 unique articles were identified, of which 53 met inclusion criteria and spanned subsites including the oral cavity (22/53 studies), nasal cavity/nasopharynx (13/53), multiple sites (10/53), larynx (5/53), trachea (2/53), and oropharynx (1/53). The most commonly observed consequences of e-cigarette use on the upper airway included: proinflammatory (15/53 studies), histological (13/53), cytotoxicity (11/53), genotoxicity (11/53), and procarcinogenic (6/53). E-cigarette humectants independently induced toxicity at multiple upper airway subsites, however, effects were generally amplified when flavoring(s) and/or nicotine were added. Across almost all studies, exposure to cigarette smoke exhibited increased toxicity in the upper airway compared with exposure to e-cigarette vapor. CONCLUSION: Current data suggest that while e-cigarettes are generally less harmful than traditional cigarettes, they possess a distinct toxicological profile that is enhanced upon the addition of flavoring(s) and/or nicotine. Future investigations into underexamined subsites, such as the oropharynx and hypopharynx, are needed to comprehensively understand the effects of e-cigarettes on the upper airway.

Poor oral health influences head and neck cancer patient survival: an International Head and Neck Cancer Epidemiology Consortium pooled analysis.

BACKGROUND: Poor oral health has been identified as a prognostic factor potentially affecting the survival of patients with head and neck squamous cell carcinoma. However, evidence to date supporting this association has emanated from studies based on single cohorts with small-to-modest sample sizes. METHODS: Pooled analysis of 2449 head and neck squamous cell carcinoma participants from 4 studies of the International Head and Neck Cancer Epidemiology Consortium included data on periodontal disease, tooth brushing frequency, mouthwash use, numbers of natural teeth, and dental visits over the 10 years prior to diagnosis. Multivariable generalized linear regression models were used and adjusted for age, sex, race, geographic region, tumor site, tumor-node-metastasis stage, treatment modality, education, and smoking to estimate risk ratios (RR) of associations between measures of oral health and overall survival. RESULTS: Remaining natural teeth (10-19 teeth: RR = 0.81, 95% confidence interval [CI] = 0.69 to 0.95; ≥20 teeth: RR = 0.88, 95% CI = 0.78 to 0.99) and frequent dental visits (>5 visits: RR = 0.77, 95% CI = 0.66 to 0.91) were associated with better overall survival. The inverse association with natural teeth was most pronounced among patients with hypopharyngeal and/or laryngeal, and not otherwise specified head and neck squamous cell carcinoma. The association with dental visits was most pronounced among patients with oropharyngeal head and neck squamous cell carcinoma. Patient-reported gingival bleeding, tooth brushing, and report of ever use of mouthwash were not associated with overall survival. CONCLUSIONS: Good oral health as defined by maintenance of the natural dentition and frequent dental visits appears to be associated with improved overall survival among head and neck squamous cell carcinoma patients.

Effect of distance of treatment center on survival for HPV-negative head and neck cancer patients.

BACKGROUND: In rural states, travel burden for complex cancer care required for head and neck squamous cell carcinoma (HNSCC) may affect patient survival, but its impact is unknown. METHODS: Patients with HPV-negative HNSCC were retrospectively identified from a statewide, population-based study. Euclidian distance from the home address to the treatment center was calculated for radiation therapy, surgery, and chemotherapy. Multivariable Cox proportional hazards models were used to examine the risk of 5-year mortality with increasing travel quartiles. RESULTS: There were 936 patients with HPV-negative HNSCC with a mean age of 60. Patients traveled a median distance of 10.2, 11.1, and 10.9 miles to receive radiation therapy, surgery, and chemotherapy, respectively. Patients in the fourth distance quartile were more likely to live in a rural location (p < 0.001) and receive treatment at an academic hospital (p < 0.001). Adjusted overall survival (OS) improved proportionally to distance traveled, with improved OS remaining significant for patients who traveled the furthest for care (third and fourth quartile by distance). Relative to patients in the first quartile, patients in the fourth had a reduced risk of mortality with radiation (HR 0.59, 95% CI 0.42-0.83; p = 0.002), surgery (HR 0.47, 95% CI 0.30-0.75; p = 0.001), and chemotherapy (HR 0.56, 95% CI 0.35-0.91; p = 0.020). CONCLUSION: For patients in this population-based cohort, those traveling greater distances for treatment of HPV-negative HNSCC had improved OS. This analysis suggests that the benefits of coordinated, multidisciplinary care may outweigh the barriers of travel burden for these patients.

Time to treatment patterns of head and neck cancer patients before and during the Covid-19 pandemic.

OBJECTIVES: The delivery of healthcare has changed significantly over the past decades. This study analyzes the clinicodemographic factors and treatment patterns of head and neck squamous cell carcinoma (HNSCC) patients between 2004 and 2020. MATERIALS AND METHODS: Retrospective cohort analysis of HNSCC patients from the National Cancer Data Base from 2004 to 2020. RESULTS: A total of 164,290 patients were included. Increased times from diagnosis to definitive surgery (TTS) were seen across all facility types (academic centers, AC; non-academic centers, NAC) between 2004 and 2019, with NAC affected more. TTS < 15 days (RR = 1.05, 95%CI:1.05-1.09) and > 75 days (1.07, 95%CI:1.05-1.09) were associated with increased mortality risk. This association was more prominent among HPV + HNSCC (RR = 1.45; 95%CI:1.18-1.78). Treatment in AC was associated with a decreased mortality risk (RR = 0.94, 95%CI:0.93-0.95). Despite the universal increase in wait times from 2004 to 2019, short-term mortality was significantly decreased from 2016 to 2019, relative to 2004-2007 (3-month mortality: RR = 0.77, 95%CI:0.70-0.85; 12-month mortality: RR = 0.80, 95%CI:0.77-0.84). Wait times decreased in 2020. CONCLUSIONS: TTS increased between 2004 and 2019, with NAC affected more. However, despite longer wait times, short-term survival increased significantly. Very short (<15 days) and very long (>75 days) TTS were associated with increased mortality risk. Patients with HPV + HNSCC have the highest increase among those treated > 75 days from diagnosis. Treatment at AC was associated with improved survival, which could be explained by the presence of multidisciplinary teams and subspecialists that may be less available at NAC. The 2021 NCDB data are required for a comprehensive analysis of wait times in 2020.

A phase 2 study of neoadjuvant chemotherapy plus durvalumab in resectable locally advanced head and neck squamous cell carcinoma.

BACKGROUND: Patients with locally advanced head and neck squamous cell cancer (HNSCC) are treated with surgery followed by adjuvant (chemo) radiotherapy or definitive chemoradiation, but recurrence rates are high. Immune checkpoint blockade improves survival in patients with recurrent/metastatic HNSCC; however, the role of chemo-immunotherapy in the curative setting is not established. METHODS: This phase 2, single-arm, multicenter study evaluated neoadjuvant chemo-immunotherapy with carboplatin, nab-paclitaxel, and durvalumab in patients with resectable locally advanced HNSCC. The primary end point was a hypothesized pathologic complete response rate of 50%. After chemo-immunotherapy and surgical resection, patients received study-defined, pathologic risk adapted adjuvant therapy consisting of either durvalumab alone (low risk), involved field radiation plus weekly cisplatin and durvalumab (intermediate risk), or standard chemoradiation plus durvalumab (high risk). RESULTS: Between December 2017 and November 2021, 39 subjects were enrolled at three centers. Oral cavity was the most common primary site (69%). A total of 35 of 39 subjects underwent planned surgical resection; one subject had a delay in surgery due to treatment-related toxicity. The most common treatment-related adverse events were cytopenias, fatigue, and nausea. Post treatment imaging demonstrated an objective response rate of 57%. Pathologic complete response and major pathologic response were achieved in 29% and 49% of subjects who underwent planned surgery, respectively. The 1-year progression-free survival was 83.8% (95% confidence interval, 67.4%-92.4%). CONCLUSIONS: Neoadjuvant carboplatin, nab-paclitaxel, and durvalumab before surgical resection of HNSCC were safe and feasible. Although the primary end point was not met, encouraging rates of pathologic complete response and clinical to pathologic downstaging were observed.

Noncanonical HPV carcinogenesis drives radiosensitization of head and neck tumors.

We analyzed transcriptional data from 104 HPV+ (Human papillomavirus) HNSCC (head and neck squamous cell carcinoma) tumors together with two publicly available sources to identify highly robust transcriptional programs (modules) which could be detected consistently despite heterogeneous sequencing and quantification methodologies. Among 22 modules identified, we found a single module that naturally subclassifies HPV+ HNSCC tumors based on a bimodal pattern of gene expression, clusters all atypical features of HPV+ HNSCC biology into a single subclass, and predicts patient outcome in four independent cohorts. The subclass-defining gene set was strongly correlated with Nuclear factor kappa B (NF-κB) target expression. Tumors with high expression of this NF-κB module were rarely associated with activating PIK3CA alterations or viral integration, and also expressed higher levels of HPHPV E2 and had decreased APOBEC mutagenesis. Alternatively, they harbored inactivating alterations of key regulators of NF-κB, TNF receptor associated factor 3 (TRAF3), and cylindromatosis (CYLD), as well as retinoblastoma protein (RB1). HPV+ HNSCC cells in culture with experimental depletion of TRAF3 or CYLD displayed increased expression of the subclass-defining genes, as well as robust radio-sensitization, thus recapitulating both the tumor transcriptional state and improved treatment response observed in patient data. Across all gene sets investigated, methylation to expression correlations were the strongest for the subclass-defining, NF-κB-related genes. Increased tumor-infiltrating CD4+ T cells and increased Estrogen receptors alpha (ERα) expression were identified in NF-κB active tumors. Based on the relatively high rates of cure in HPV+ HNSCC, deintensification of therapy to reduce treatment-related morbidity is being studied at many institutions. Tumor subclassification based on oncogenic subtypes may help guide the selection of therapeutic intensity or modality for patients with HPV+ HNSCC.

Human Immunodeficiency Virus Is Associated With Poor Overall Survival Among Patients With Head and Neck Cancer.

BACKGROUND: Head and neck squamous cell cancer (HNSCC) occurs at higher rates among persons with HIV (PWH). This study compares the impact of sociodemographic and clinicopathologic characteristics on outcomes among PWH-HNSCC compared with HNSCC patients without HIV. METHODS: Patient data from HNSCC individuals were collected at a single academic hospital center between 2002 and 2018. Forty-eight patients with HIV (HIV-HNSCC) and 2894 HNSCC patients without HIV were included. Multivariate analysis determined predictors of survival using Cox proportional hazards regression model. HIV-positive and -negative tumors were analyzed by quantitative immunofluorescence for expression of CD4, CD8, CD20 and PD-L1. RESULTS: HIV-HNSCC patients had a lower median overall survival than HNSCC patients without HIV (34 [18-84] vs 94 [86-103] months; P < .001). In multivariate analysis that included age, sex, race/ethnicity, stage, site, tobacco use, time to treatment initiation, and insurance status, HIV was an independent predictor of poorer survival, with a hazard ratio of 1.98 (95% CI: 1.32-2.97; P < .001). PWH with human papillomavirus (HPV)-positive oropharyngeal tumors also had worse prognosis than HPV-positive oropharyngeal tumors in the population without HIV (P < .001). The tumor microenvironment among HIV-HNSCC patients revealed lower intratumoral CD8 infiltration among HIV+ HPV+ tumors compared with HIV- HPV+ tumors (P = .04). CONCLUSIONS: HIV-HNSCC patients had worse prognosis than the non-HIV population, with HIV being an independent predictor of poor clinical outcomes when accounting for important sociodemographic and clinicopathologic factors. Our findings highlight differences in tumor biology that require further detailed characterization in large cohorts and increased inclusion of PWH in immunotherapy trials.

Diagnostic accuracy of FNA to determine HPV status in HPV-associated oropharyngeal squamous cell carcinoma.

PURPOSE/OBJECTIVE(S): Accurate diagnosis of human papillomavirus (HPV) status in oropharyngeal squamous cell carcinoma (OPSCC) affects prognosis and can alter the treatment plan. We evaluated the diagnostic accuracy of FNA biopsies to determine malignancy and HPV status in OPSCC at our institution. METHODS: Pathology samples from consecutive patients with pathologically confirmed HPV-associated OPSCC who underwent FNA of a cervical lymph node during initial diagnostic work-up were retrospectively analyzed between November 2015 and August 2021. RESULTS: Initial FNA was diagnostic for malignancy in 109/148 (73.6%) patients and non-diagnostic in 39/148 (26.4%). P16 staining of FNAs positive for malignancy showed: 54/109 (49.5%) p16 positive, 6/109 (5.5%) p16 negative, 49/109 (45.0%) p16 indeterminate. In patients with an initial non-diagnostic sampling or p16 indeterminate, repeat FNA was performed in 30/88 (34.1%) patients. Of the 30 repeat FNAs: 23/30 (76.7%) were diagnostic of malignancy and 7/30 (23.3%) remained non-diagnostic for malignancy. Of the 23 repeat FNAs diagnostic of malignancy: 16/23 (69.6%) were p16 positive and 7/23 (30.4%) were p16 indeterminate. In summary, 88/148 (59.5%) initial FNAs and 14/30 (46.7%) of repeat FNAs were non-diagnostic of malignancy or p16 indeterminate. Final yield of FNA biopsies (initial and first repeat FNA) to diagnose malignancy and p16 status was 70/148 (47.3%). CONCLUSIONS: Fine needle aspirations of lymph nodes in patients with HPV-associated OPSCC are frequently non-diagnostic for malignancy or indeterminate for p16 status, requiring repeat FNA or biopsy of the primary site. This can potentially cause treatment delay and increase morbidity and cost to the patient.

Direct Comparison of HPV16 Viral Genomic Integration, Copy Loss, and Structural Variants in Oropharyngeal and Uterine Cervical Cancers Reveal Distinct Relationships to E2 Disruption and Somatic Alteration.

Squamous cell carcinoma of the oropharynx caused by HPV type 16 (HPV16+ OPSCC) is the most common HPV-associated malignancy in the USA and has many molecular differences from uterine cervical squamous cell carcinoma (UCSCC). Our understanding of HPV oncogenesis relied on studies of UCSCC revealing a consensus model reliant on HPV integration with a loss of E2. Here, we compare patterns of HPV integration in UCSCC and OPSCC by analysis of affinity capture sequencing of the HPV16 genome in 104 OPSCC and 44 UCSCC tumors. These cohorts were contemporaneously sequenced using an identical strategy. Integration was identified using discordant read pair clustering and assembly-based approaches. Viral integration sites, structural variants, and copy losses were examined. While large-scale deep losses of HPV16 genes were common in UCSCC and were associated with E2 loss, deep copy losses of the HPV16 genome were infrequent in HPV16+ OPSCC. Similarly, structural variants within HPV16 favored E2 loss in UCSCC but not OPSCC. HPV16 integration sites were non-random, with recurrent integration hot-spots identified. OPSCC tumors had many more integration sites per tumor when compared to UCSCC and had more integration sites in genomic regions with high gene density. These data show that viral integration and E2 disruption are distinct in UCSCC and OPSCC. Our findings also add to growing literature suggesting that HPV tumorigenesis in OPSCC does not follow the model developed based on UCSCC.

Development of a Novel Molecular Test for Determining HPV Integration Status in HPV-Positive Oropharynx Cancers.

This diagnostic study describes the development of an assay for human papillomavirus­driven cancers of the oropharynx and the role viral integration could play in the process.

Tumor Cell Extrinsic Synaptogyrin 3 Expression as a Diagnostic and Prognostic Biomarker in Head and Neck Cancer.

Over 70% of oropharyngeal head and neck squamous cell carcinoma (HNSC) cases in the United States are positive for human papillomavirus (HPV) yet biomarkers for stratifying oropharyngeal head and neck squamous cell carcinoma (HNSC) patient risk are limited. We used immunogenomics to identify differentially expressed genes in immune cells of HPV(+) and HPV(-) squamous carcinomas. Candidate genes were tested in clinical specimens using both quantitative RT-PCR and IHC and validated by IHC using the Carolina Head and Neck Cancer Study (CHANCE) tissue microarray of HNSC cases. We performed multiplex immunofluorescent staining to confirm expression within the immune cells of HPV(+) tumors, receiver operating characteristic (ROC) curve analyses, and assessed survival outcomes. The neuronal gene Synaptogyrin-3 (SYNGR3) is robustly expressed in immune cells of HPV(+) squamous cancers. Multiplex immunostaining and single cell RNA-seq analyses confirmed SYNGR3 expression in T cells, but also unexpectedly in B cells of HPV(+) tumors. ROC curve analyses revealed that combining SYNGR3 and p16 provides more sensitivity and specificity for HPV detection compared to p16 IHC alone. SYNGR3-high HNSC patients have significantly better prognosis with five-year OS and DSS rates of 60% and 71%, respectively. Moreover, combining p16 localization and SYNGR3 expression can further risk stratify HPV(+) patients such that high cytoplasmic, low nuclear p16 do significantly worse (Hazard Ratio, 8.6; P = 0.032) compared to patients with high cytoplasmic, high nuclear p16. SYNGR3 expression in T and B cells is associated with HPV status and enhanced survival outcomes of HNSC patients.

Exploring ABOBEC3A and APOBEC3B substrate specificity and their role in HPV positive head and neck cancer.

APOBEC3 family members are cytidine deaminases catalyzing conversion of cytidine to uracil. Many studies have established a link between APOBEC3 expression and cancer development and progression, especially APOBEC3A (A3A) and APOBEC3B (A3B). Preclinical studies with human papillomavirus positive (HPV+) head and neck squamous cell carcinoma (HNSCC) and clinical trial specimens revealed induction of A3B, but not A3A expression after demethylation. We examined the kinetic features of the cytidine deaminase activity for full length A3B and found that longer substrates and a purine at -2 position favored by A3B, whereas A3A prefers shorter substrates and an adenine or thymine at -2 position. The importance and biological significance of A3B catalytic activity rather than A3A and a preference for purine at the -2 position was also established in HPV+ HNSCCs. Our study explored factors influencing formation of A3A and A3B-related cancer mutations that are essential for understanding APOBEC3-related carcinogenesis and facilitating drug discovery.

Comprehensive Viral Genotyping Reveals Prognostic Viral Phylogenetic Groups in HPV16-Associated Squamous Cell Carcinoma of the Oropharynx.

Human papillomavirus-positive (HPV+) squamous cell carcinoma of the oropharynx (OPSCC) is the most prevalent HPV-associated malignancy in the United States and is primarily caused by HPV subtype 16 (HPV16). Favorable treatment outcomes have led to increasing interest in treatment deescalation to reduce treatment-related morbidity. Prognostic biomarkers are needed to identify appropriately low-risk patients for reduced treatment intensity. Targeted DNA sequencing including all HPV16 open reading frames was performed on tumors from 104 patients with HPV16+ OPSCC treated at a single center. Genotypes closely related to the HPV16-A1 reference were associated with increased numbers of somatic copy-number variants in the human genome and poor recurrence-free survival (RFS). Genotypes divergent from HPV16-A1 were associated with favorable RFS. These findings were independent of tobacco smoke exposure. Total RNA sequencing was performed on a second independent cohort of 89 HPV16+ OPSCC cases. HPV16 genotypes divergent from HPV16-A1 were again validated in this independent cohort, to be prognostic of improved RFS in patients with moderate (less than 30 pack-years) or low (no more than 10 pack-years) of tobacco smoke exposure. In summary, we show in two independent cohorts that viral sequence divergence from the HPV16-A1 reference is correlated with improved RFS in patients with moderate or low tobacco smoke exposure. IMPLICATIONS: HPV16 genotype is a potential biomarker that could be easily adopted to guide therapeutic decision-making related to deescalation therapy.

Activation of the CREB Coactivator CRTC2 by Aberrant Mitogen Signaling promotes oncogenic functions in HPV16 positive head and neck cancer.

Head and neck squamous cell carcinoma (HNSCC) is the 6th most common cancer worldwide and incidence rates are continuing to rise globally. Patients often present with locally advanced disease and a staggering 50% chance of relapse following treatment. Aberrant activation of adaptive response signaling pathways, such as the cAMP/PKA pathway, induce an array of genes associated with known cancer pathways that promote tumorigenesis and drug resistance. We identified the cAMP Regulated Transcription Coactivator 2 (CRTC2) to be overexpressed and constitutively activated in HNSCCs and this confers poor prognosis. CRTCs are regulated through their subcellular localization and we show that CRTC2 is exclusively nuclear in HPV(+) HNSCC, thus constitutively active, due to non-canonical Mitogen-Activated Kinase Kinase 1 (MEKK1)-mediated activation via a MEKK1-p38 signaling axis. Loss-of-function and pharmacologic inhibition experiments decreased CRTC2/CREB transcriptional activity by reducing nuclear CRTC2 via nuclear import inhibition and/or by eviction of CRTC2 from the nucleus. This shift in localization was associated with decreased proliferation, migration, and invasion. Our results suggest that small molecules that inhibit nuclear CRTC2 and p38 activity may provide therapeutic benefit to patients with HPV(+) HNSCC.

NF-κB over-activation portends improved outcomes in HPV-associated head and neck cancer.

Evolving understanding of head and neck squamous cell carcinoma (HNSCC) is leading to more specific diagnostic disease classifications. Among HNSCC caused by the human papilloma virus (HPV), tumors harboring defects in TRAF3 or CYLD are associated with improved clinical outcomes and maintenance of episomal HPV. TRAF3 and CYLD are negative regulators of NF-κB and inactivating mutations of either leads to NF-κB overactivity. Here, we developed and validated a gene expression classifier separating HPV+ HNSCCs based on NF-κB activity. As expected, the novel classifier is strongly enriched in NF-κB targets leading us to name it the NF-κB Activity Classifier (NAC). High NF-κB activity correlated with improved survival in two independent cohorts. Using NAC, tumors with high NF-κB activity but lacking defects in TRAF3 or CYLD were identified; thus, while TRAF3 or CYLD gene defects identify the majority of tumors with NF-κB activation, unknown mechanisms leading to NF-kB activity also exist. The NAC correctly classified the functional consequences of two novel CYLD missense mutations. Using a reporter assay, we tested these CYLD mutations revealing that their activity to inhibit NF-kB was equivalent to the wild-type protein. Future applications of the NF-κB Activity Classifier may be to identify HPV+ HNSCC patients with better or worse survival with implications for treatment strategies.

Characteristics and outcomes associated with anxiety and depression in a head and neck cancer survivorship cohort.

PURPOSE: To assess the prevalence and predictors of mental health disorders (MDHs) among head and neck squamous cell carcinoma (HNSCC) survivors, and the association with health-related quality of life (HRQOL), pain, and survival outcomes. MATERIALS AND METHODS: This was a retrospective, cross-sectional study of HNSCC survivors surveyed at an outpatient oncology clinic from May 2012 through July 2016. RESULTS: Among 198 HNSCC survivors, 21% reported a MHD. Female sex (OR 6.60, 95% CI 2.08 to 20.98; p = 0.001) and Medicare insurance status (OR 4.95, 95% CI 1.52 to 16.11; p = 0.008) were significant predictors of reporting a MHD in the fully adjusted model. Patients reporting a MHD reported significantly worse pain (p < 0001) and worse HRQOL on the PROMIS Physical (p < 0.001), PROMIS Mental (p < 0.001), and FACT-GP (p < 0.026) questionnaires. Diagnosis of a MHD was not correlated with 5-year OS (74% vs. 84%; p = 0.087). CONCLUSION: Initiatives for early identification and intervention of MHDs as part of survivorship initiatives may engender clinically meaningful outcomes in head and neck cancer.

Socioeconomic status, access to care, risk factor patterns, and stage at diagnosis for head and neck cancer among black and white patients.

BACKGROUND: Little is known about how factors combine to influence progression of squamous cell carcinoma of the head and neck (HNSCC). We aimed to evaluate multidimensional influences of factors associated with HNSCC stage by race. METHODS: Using retrospective data, patients with similar socioeconomic status (SES), access to care (travel time/distance), and behavioral risk factors (tobacco/alcohol use and dental care) were grouped by latent class analysis. Relative frequency differences (RFD) were calculated to evaluate latent classes by stage, race, and p16 status. RESULTS: We identified three latent classes. Advanced T-stage was higher for black (RFD = +20.2%; 95% CI: -4.6 to 44.9) than white patients (RFD = +10.7%; 95% CI: 2.1-19.3) in the low-SES/high-access/high-behavioral risk class and higher for both black (RFD = +29.6%; 95% CI: 4.7-54.5) and white patients (RFD = +23.9%; 95% CI: 15.2-32.6) in the low-SES/low-access/high-behavioral risk class. CONCLUSION: Results suggest that SES, access to care, and behavioral risk factors combine to underly the association with advanced T-stage. Additionally, differences by race warrant further investigation.
