Long non-coding RNA ELDR enhances oral cancer growth by promoting ILF3-cyclin E1 signaling

Oral squamous cell carcinoma (OSCC) is the sixth most common cancer with a 5-year overall survival rate of 50%. Thus, there is a critical need to understand the disease process, and to identify improved therapeutic strategies. Previously, we found the long non-coding RNA (lncRNA) EGFR long non-coding downstream RNA (ELDR) induced in a mouse tongue cancer model; however, its functional role in human oral cancer remained unknown. Here, we show that ELDR is highly expressed in OSCC patient samples and in cell lines. Overexpression of ELDR in normal non-tumorigenic oral keratinocytes induces cell proliferation, colony formation, and PCNA expression. We also show that ELDR depletion reduces OSCC cell proliferation and PCNA expression. Proteomics data identifies the RNA binding protein ILF3 as an interacting partner of ELDR. We further show that the ELDR-ILF3 axis regulates Cyclin E1 expression and phosphorylation of the retinoblastoma (RB) protein. Intratumoral injection of ELDR-specific siRNA reduces OSCC and PDX tumor growth in mice. These findings provide molecular insight into the role of ELDR in oral cancer and demonstrate that targeting ELDR has promising therapeutic potential.

Opioid Usage and Prescribing Predictors Following Transoral Robotic Surgery for Oropharyngeal Cancer

OBJECTIVE/HYPOTHESIS

Pain management following transoral robotic surgery (TORS) varies widely. We aim to quantify opioid usage following TORS for oropharyngeal squamous cell carcinoma (OPSCC) and identify prescribing predictors.

STUDY DESIGN

Retrospective cohort study.

METHODS

A consecutive series of 138 patients undergoing TORS for OPSCC were reviewed from 2016 to 2019. Opioid usage (standardized to morphine milligram equivalents [MME]) was gathered for 12 months post-surgery via prescribing record cross-check with the Massachusetts Prescription Awareness Tool.

RESULTS

Of 138 OPSCC TORS patients, 92.8% were human papillomavirus (HPV) positive. Adjuvant therapy included radiation (XRT;67.4%) and chemoradiation (cXRT;6.5%). Total MME usage from start of treatment averaged 1395.7 MMEs with 76.4% receiving three prescriptions or less. Categorical analysis showed age <65, male sex, overweight BMI, lower frailty, former smokers, HPV+, higher T stage, and BOT subsite to be associated with increased MMEs. Adjuvant therapy significantly increased MMEs (TORS+XRT:1646.2; TORS+cXRT:2385.0; TORS alone:554.7 [P < .001]) and 12-month opioid prescription totals (TORS+XRT:3.2; TORS+cXRT:5.5; TORS alone:1.6 [P < .001]). Adjuvant therapy increased time to taper (total MME in TORS alone versus TORS+XRT/cXRT: 0 to 3 months:428.2 versus 845.5, 4 to 6 months:46.8 versus 541.8, 7 to 9 months:12.4 versus 178.6, 10 to 12 months:11.0 versus 4.4,[P < .001]). Positive predictors of opioid prescribing at the 4- to 6-month and 4- to 12-month intervals included adjuvant therapy (odds ratio [OR]:5.56 and 4.51) and mFI-5 score ≥3 (OR:36.67 and 31.94). Following TORS at 6-, 9-, and 12-month, 15.7%, 6.6%, and 4.1% were still using opioids.

CONCLUSIONS

In OPSCC treated with TORS, opioid use tapers faster for surgery alone versus with adjuvant therapy. Opioid prescribing risks include adjuvant therapy and higher frailty index.

Hospitalization rates and 30-day all-cause mortality among head and neck cancer patients and survivors with COVID-19

•

We note high 30-day all-cause mortality for HNC patients admitted with COVID-19.

•

ICU admission and residing in a LTC facility predicted poor outcomes.

•

Most deaths were in HNC survivors and not in those on active cancer therapy.

Background

The impact of COVID-19 on patients with cancer is emerging, but data are urgently needed for head and neck cancer (HNC) patients or survivors who are inherently high-risk for severe illness and mortality with SARS-CoV-2 infection.

Methods

This multi-institution, academic cohort study collected comprehensive data on clinical risk factors, COVID-19 symptoms and viral testing patterns, information about hospitalization rates, and predictors of survival among HNC patients with active disease or in remission. The primary endpoint was 30-day all-cause mortality from the date of confirmed COVID-19. We performed multivariate analysis to understand the prognostic value of clinical and laboratory parameters on outcomes.

Results

Thirty-two patients with COVID-19 and HNC were included. Median age was 70 (range: 38–91) with 38% aged 75+, and 34% resided in long-term care facilities (LTCF). Thirteen (41%) had active cancer, with 6 (19%) on cancer therapy within 4 weeks of COVID-19 diagnosis. New or worsening cough and fatigue were the most commonly reported presenting symptoms. More than 30% required >1 SARS-CoV-2 test before confirming a positive result. Twenty (63%) required hospitalization. At data cutoff, 7 (22%) had died (1 on active cancer treatment), with a 30-day all-cause mortality of 18.9% (95%CI: 11.4–33.6) among all patients, and 71.5% (95%CI: 38.2–92.3) among those requiring intensive care unit (ICU) admission. ICU admission and residing in a LTCF predicted worse outcomes (p < 0.01), while age, gender, and recent treatment did not.

Conclusions

We observed high 30-day all-cause mortality among HNC patients with COVID-19, but most were not on active cancer therapy.

In-Practice Endocrine Surgery Fellowship: A Novel Training Model

OBJECTIVE

Endocrine surgery is an expanding field within otolaryngology. We hypothesized that a novel endocrine surgery fellowship model for in-practice otolaryngologists could result in expert-level training.

STUDY DESIGN

Qualitative clinical study with chart review.

SETTING

Urban community practice and academic medical center.

METHODS

Two board-certified general otolaryngologists collaborated with a senior endocrine surgeon to increase their endocrine surgery expertise between March 2015 and December 2017. The senior surgeon provided intensive surgical training to both surgeons for all of their endocrine surgeries. Both parties collaborated with endocrinology to coordinate medical care and receive referrals. All patients undergoing endocrine surgery during this time frame were reviewed retrospectively.

RESULTS

A total of 235 endocrine surgeries were performed. Of these, 198 thyroid surgeries were performed, including 98 total thyroidectomies (48%), 90 lobectomies (45%), and 10 completion thyroidectomies (5%). Sixty cases demonstrated papillary thyroid carcinoma, 11 follicular thyroid carcinoma, and 4 medullary thyroid carcinoma. Neck dissections were performed in 14 of the cases. Thirty-seven parathyroid explorations were performed. There were no reports of permanent hypoparathyroidism. Thirteen patients (5.5%) developed temporary hypoparathyroidism. Six patients (2.5%) developed postoperative seroma. Three patients (1.3%) developed postoperative hematomas requiring reoperation. One patient (0.4%) developed permanent vocal fold paralysis, and 3 patients (1.3%) had temporary dysphonia. Thirty-five of 37 (94.5%) parathyroid explorations resulted in biochemical resolution of the patient's primary hyperparathyroidism.

CONCLUSION

This is the first description of a new fellowship paradigm where a senior surgeon provides fellowship training to attending surgeons already in practice.

Role of physician density in predicting stage and survival for head and neck squamous cell carcinoma

BACKGROUND

Identifying and linking barriers to access to head and neck cancer care, specifically provider density, to stage of diagnosis and survival outcomes is important to serve as a foundation for policy interventions.

METHODS

Retrospective cohort study using patients with head and neck squamous cell (HNSCC) in the Surveillance, Epidemiology, and End Results (SEER) database from 2007 to 2016 and Area Resource File. Primary outcomes included stage of presentation and cancer-specific 5-year survival and relation to provider density.

RESULTS

The initial cohort consisted of 18 342 patients with oral cavity, 21 809 oropharyngeal, 15 860 laryngeal, and 2887 patients with hypopharyngeal malignancy. Non-Hispanic Black race and being uninsured increased the odds of presenting with advanced stage HNSCC and increased hazard of death. There was no significant and consistent association identified between Health Service Areas provider density and advanced stage at diagnosis or cancer-specific 5-year mortality.

CONCLUSIONS

Provider density of otolaryngologists and primary care physicians and dentists was not significantly associated with stage of presentation or cancer-specific survival for HNSCC while race and insurance status remained independent predictors for worse outcomes.

Margin Practices in Oral Cavity Cancer Resections: Survey of American Head and Neck Society Members

OBJECTIVES/HYPOTHESIS

To investigate the definition of a clear margin and the use of frozen section (FS) among practicing head and neck surgeons in oral cancer management.

STUDY DESIGN

Cross-sectional survey.

METHODS

We designed a survey that was sent to American Head and Neck Society (AHNS) members via an email link.

RESULTS

A total of 185 (13% of 1,392) AHNS members completed our survey. Most surgeons surveyed (96.8%) use FS to supplement oral cavity squamous cell carcinoma resections. Fifty-five percent prefer a specimen-based approach. The majority of respondents believe FS is efficacious in guiding re-resection of positive margins, with 81% considering the new margin to be negative. More than half of respondents defined a distance of >5 mm on microscopic examination as a negative margin.

CONCLUSIONS

To avoid oral cancer resections that result in positive margins on final analysis, and thus the need for additional therapy, most surgeons surveyed use FS. A majority of surveyed surgeons now prefer a specimen-based approach to margin assessment. Although there is a debate on what constitutes a negative margin, most surgeons surveyed believe it to be >5 mm on microscopic examination.

Risk Factors for Laryngectomy for Dysfunctional Larynx After Organ Preservation Protocols: A Case-Control Analysis

Objective

(1) To identify factors associated with severe dysfunctional larynx leading to total laryngectomy after curative treatment of head and neck squamous cell carcinoma and (2) to describe swallowing and voice outcomes.

Study Design

Retrospective single-institution case-control study.

Setting

Tertiary care referral center.

Methods

A 10-year chart review was performed for patients who had previously undergone radiation or chemoradiation for head and neck mucosal squamous cell carcinoma and planned to undergo total laryngectomy for dysfunctional larynx, as well as a control group of matched patients. Controls were patients who had undergone radiation or chemoradiation for mucosal squamous cell carcinoma but did not have severe dysfunction warranting laryngectomy; these were matched to cases by tumor subsite, T stage, and time from last treatment to video swallow study. Main outcomes assessed were postoperative diet, alaryngeal voice, pharyngeal dilations, and complications.

Results

Twenty-six patients were scheduled for laryngectomy for dysfunctional larynx, of which 23 underwent surgery. Originally treated tumor subsites included the larynx, oropharynx, hypopharynx, oral cavity, and a tumor of unknown origin. The median time from end of cancer treatment to laryngectomy was 11.5 years. All cases were feeding tube or tracheostomy dependent or both prior to laryngectomy. As compared with matched controls, cases were significantly less likely to have undergone IMRT (intensity-modified radiotherapy) and more likely to have pulmonary comorbidities. Eighty-nine percent of cases with follow-up achieved functional alaryngeal voice, and all were able to have oral intake.

Conclusion

Non-IMRT approaches and pulmonary comorbidities are associated with laryngectomy for dysfunction after radiation or chemoradiation.

National Database Research in Head and Neck Reconstructive Surgery: A Call for Increased Transparency and Reproducibility

OBJECTIVE

To reproduce a published study comparing outcomes of patients who underwent microvascular reconstruction by plastic surgeons and otolaryngologists and to examine how case selection and methodology using the National Surgical Quality Improvement Program (NSQIP) data set can affect results and conclusions.

STUDY DESIGN

Cross-sectional analysis of US national database.

SETTING

American College of Surgeons National Surgical Quality Improvement Program (NSQIP) from 2005 to 2017.

SUBJECTS AND METHODS

A recently published study that used the NSQIP database to compare outcomes after head and neck free tissue transfer between plastic surgeons and otolaryngologists was reproduced. Different approaches to case selection and statistical analysis were evaluated and their effects on statistical significance and study conclusions were compared.

RESULTS

When all cases of free tissue transfer, captured in NSQIP between 2005 and 2017, were compared between plastic surgery and otolaryngology, plastic surgery patients appeared to have lower rates of complications and length of stay. However, a more in-depth analysis demonstrated that these results were confounded by older and sicker otolaryngology patients. A second analysis of the same NSQIP data, limited to only head and neck oncologic reconstructions, demonstrated that otolaryngology patients had fewer complications on univariate and multivariable analysis.

CONCLUSION

We demonstrated how case selection and analysis can significantly affect results. It is incumbent upon researchers who use NSQIP and other publicly available data sets to fully detail their methodology to allow other researchers to reproduce and evaluate their work and for the journal editorial process to carefully evaluate the methodology and conclusions of their contributing authors.

State Medicaid expansion status, insurance coverage and stage at diagnosis in head and neck cancer patients

OBJECTIVES

Only one in three head and neck cancer (HNC) patients present with early-stage disease. We aimed to quantify associations between state Medicaid expansions and changes in insurance coverage rates and stage at diagnosis of HNC.

METHODS

Using a quasi-experimental difference-in-differences (DID) approach and data from 26,330 cases included in the Surveillance, Epidemiology, and End Results program (2011-2015), we retrospectively examined changes in insurance coverage and stage at diagnosis of adult HNC in states that expanded Medicaid (EXP) versus those that did not (NEXP).

RESULTS

There was a significant increase in Medicaid coverage in EXP (+1.6 percentage point (PP) versus) vs. NEXP (-1.8 PP) states (3.36 PP, 95% CI = 1.32, 5.41; p = 0.001), and this increase was mostly among residents of low income and education counties. We also observed a reduction in uninsured rates among HNC patients in low income counties (-4.17 PP, 95% CI = -6.84, -1.51; p = 0.002). Overall, early stage diagnosis rates were 28.3% (EXP) vs. 26.7% (NEXP), with significant increases in early stage diagnosis post-Medicaid expansion among young adults, 18-34 years (17.2 PP, 95% CI - 1.34 to 33.1, p = 0.034), females (7.54 PP, 95% CI = 2.00 to 13.10, p = 0.008), unmarried patients (3.83 PP, 95% CI = 0.30-7.35, p = 0.033), and patients with lip cancer (13.5 PP, 95% CI = 2.67-24.3, p = 0.015).

CONCLUSIONS

Medicaid expansion is associated with improved insurance coverage rates for HNC patients, particularly those with low income, and increases in early stage diagnoses for young adults and women.

Change in stage of presentation of head and neck cancer in the United States before and after the affordable care act

OBJECTIVE/HYPOTHESIS

Early diagnosis and stage at presentation, two prognostic factors for survival among patients with head and neck cancer (HNC), are significantly impacted by a patient's health insurance status. We aimed to assess the impact of the Patient Protection and Affordable Care Act (ACA) on stage at presentation across socioeconomic and demographic subpopulations of HNC patients in the United States.

STUDY DESIGN

Retrospective data analysis.

METHODS

The National Cancer Database, a hospital-based cancer database (2011-2015), was queried for adults aged 18-64 years and diagnosed with a malignant primary HNC. The outcome of interest was change in early-stage diagnoses between 2011-2013 (pre-ACA) and 2014-2015 (post-ACA) using logistic regression models.

RESULTS

A total of 91,137 HNC cases were identified in the pre-ACA (n = 53,726) and post-ACA (n = 37,411) years. Overall, the odds of early-stage diagnoses did not change significantly post-ACA (aOR = 0.97, 95 % CI 0.94, 1.00; p = 0.081). However, based on health insurance status, HNC patients with Medicaid were significantly more likely to present with early-stage disease post-ACA (aOR = 1.12, 95 % CI 1.03, 1.21; p = 0.007). We did not observe increased odds of early-stage presentation for other insurance types. Males were less likely to present with early-stage disease, pre- or post-ACA.

CONCLUSIONS

We demonstrate a significant association between ACA implementation and increased early-stage presentation among Medicaid-enrolled HNC patients. This suggests that coverage expansions through the ACA may be associated with increased access to care and may yield greater benefits among low-income HNC patients.

Comparison of Intraoperative Sonography and Histopathologic Evaluation of Tumor Thickness and Depth of Invasion in Oral Tongue Cancer: A Pilot Study

BACKGROUND AND PURPOSE

For primary squamous cell carcinoma of the oral tongue, accurate assessment of tumor thickness and depth of invasion is critical for staging and operative management. Currently, typical imaging modalities used for preoperative staging are CT and MR imaging. Intraoperatively, CT or MR imaging cannot provide real-time guidance, and assessment by manual palpation is limited in precision. We investigated whether intraoperative sonography is a feasible technique for assessment of tumor thickness and depth of invasion and validated its accuracy by comparing it with histopathologic evaluation of the resected specimen.

MATERIALS AND METHODS

Twenty-six patients with squamous cell carcinoma of the oral tongue who underwent tumor resection by a single surgeon between March 31, 2016, and April 26, 2019, were prospectively identified. Intraoperative sonography was obtained in planes longitudinal and transverse to the long axis of the tumor. Twenty-two patients had archived images that allowed measurements of tumor thickness and depth of invasion sonographically. Two patients had dysplasia and were excluded. The remaining 20 patients had histologic tumor thickness and histologic depth of invasion measured by a single pathologist.

RESULTS

The mean sonographic tumor thickness was 7.5  ± 3.5 mm, and the mean histologic tumor thickness was 7.0  ± 4.2 mm. Mean sonographic depth of invasion and histologic depth of invasion were 6.6  ± 3.4  and 6.4 ± 4.4 mm, respectively. There was excellent correlation between sonographic and histologic measurements for both tumor thickness and depth of invasion with Pearson correlation coefficients of 0.95 (95% CI, 0.87-0.98) and 0.95 (95% CI, 0.87-0.98), respectively.

CONCLUSIONS

Intraoperative sonography can provide reliable, real-time assessment of the extent of tongue tumors.

Sociodemographic correlates of head and neck cancer survival among patients with metastatic disease

BACKGROUND

To describe sociodemographic factors associated with head and neck cancer (HNC) survival among patients with distant metastatic disease.

METHODS

We retrospectively analyzed national data for 2889 adult patients with metastatic HNC (2007-2015). We used Fine and Gray competing risks proportional hazard models, stratified by oropharyngeal cancer status, controlled for sociodemographic factors (age, sex, race/ethnicity, marital status, and insurance status), and accounted for multiple testing.

RESULTS

Median survival time was 11 months (15 months for patients married/partnered; 13 months for patients with non-Medicaid insurance; P < .01). Among patients with oropharyngeal cancer, being married/partnered was associated with lower mortality hazard (sdHR_{divorced/separated} = 1.37, 97.5% confidence interval [CI] = 1.07, 1.75; and sdHR_{never married} = 1.43, 97.5% CI = 1.14, 1.80), as was having non-Medicaid insurance (sdHR_uninsured = 1.44, 97.5% CI = 1.02, 2.04).

CONCLUSIONS

Health insurance and marital status are sociodemographic factors associated with survival among HNC patients with distant metastatic disease, especially in oropharyngeal cases.

Revaluation of Otolaryngologic Procedures With 10- and 90-Day Global Periods in the Medicare Physician Fee Schedule

A recent investigation by the Centers for Medicare and Medicaid Services (CMS) suggests that physicians provide fewer postoperative visits (POVs) than expected for procedures with 10- and 90-day global periods. CMS is now contemplating revaluation of these procedures, which could result in lower Medicare payments to otolaryngologists. To estimate the impact of such reform on otolaryngologic procedures, we conducted a secondary subgroup analysis of CMS-contracted research, which used claims-based estimates of POVs to revalue procedures with 10- and 90-day global periods. Among the top 10 highest volume procedures performed in 2018, the proportion of median physician-reported to CMS-expected POVs ranged between 0.0% (myringotomy ± ventilation tube insertion, mouth biopsy, and complex wound repair) and 40.0% (total thyroidectomy). The top 5 procedures accounted for nearly three-quarters ($6.2 million and $8.6 million; 72.6%) of the estimated Medicare payment reduction. Further study is necessary to guide the development of equitable and effective payment reform.

Abstract D128: Oropharyngeal cancer incidence-based mortality trends in the United States, 1985-2016

Objective: The last three decades in the United States have seen oropharyngeal cancer emerge as an important human papillomavirus (HPV)-associated cancer, with about three-quarters of cases thought to be positive for HPV. It has dramatically increased in incidence and recently surpassed cervical cancer as the leading HPV-associated cancer. While positive HPV tumor status generally portends better survival probability compared with non-HPV related head and neck cancer, there is a paucity of data describing mortality trends. This study aimed to describe trends in oropharyngeal cancer incidence-based mortality in the United States in the last three decades. Methods: We estimated age-adjusted incidence-based mortality rates (AAMR) from first primary oropharyngeal squamous cell carcinoma (OPSCC), using the Surveillance, Epidemiology, and End Results (SEER) 9 database from 1985-2016. To prevent later years from having a cumulatively larger set of patients diagnosed in the past, we only included OPSCC patients who died within 10 years of diagnosis. AAMRs were stratified by race, sex, and age at death and were presented per 100,000 person-years. Rate ratios (RRs) determined which groups had significantly different AAMRs, and Joinpoint regression calculated which groups had significant increases/decreases in annual AAMRs over time through annual percentage changes (APCs) and average APCs (AAPCs). We used 95% confidence intervals (CIs) to determine significant RRs, APCs, and AAPCs. Results: This study included 12,102 patients who died from first primary OPSCC from 1985-2016 with an AAMR of 1.16 per 100,000 person-years. AAMRs among males were 3.58 times higher than for females (RR = 3.58, 95% CI 3.43, 3.73). AAMRs among blacks were about 2 times higher than for whites (RR = 2.06, 95% CI 1.96, 2.16) but were about 60% lower for other race than whites (RR = 0.37, 95% CI 0.34, 0.42). From 1985-2009, AAMRs for first primary OPSCC decreased approximately 1.92% annually (APC = -1.92, 95% CI -2.27, -1.56) but remained stable from 2009-2016, which resulted in an average annual decrease of -1.31% from 1985-2016 (AAPC = -1.31, 95% CI -1.84, -0.78). When stratified by race or sex, all groups exhibited significant mortality rates decrease, however decrease was significantly greater among whites than blacks (white AAPC1985-2016 = -0.76; 95% CI -1.33, -0.17 vs black AAPC1985-2016 = -3.36; 95% CI -3.85, -2.87). AAMRs significantly decreased among 65+ year olds (AAPC = -0.88, 95% CI -1.63, -0.13), while AAMRs for 15-39 and 40-64-year olds exhibited non-significant decreases. Conclusions: While there has been significant decrease in oropharyngeal cancer mortality in the last three decades in the United States across age groups, races/ethnicity, and gender, there remained a significant mortality gap between blacks and whites, highlighting the persistent cancer-related disparity in the United States.

Abstract B088: Health insurance status, stage at presentation and survival among female patients with head and neck cancer

Introduction: Head and neck cancer epidemiology has historically focused on the burden of disease among males. Despite a concerning increase in the incidence of certain types of head and neck cancer among females, females with head and neck cancer continue to represent an understudied and overlooked patient population. While previous studies have established that health insurance status is associated with mortality and stage at presentation among patients with head and neck cancer, the impact of health insurance on female patients with head and neck cancer is not well understood. This study describes incidence trends in stage at presentation and investigates the association between health insurance status, stage at presentation and survival among female patients with head and neck cancer.

Methods: This retrospective cohort study included 18,923 female patients from the Surveillance, Epidemiology, and End Results (SEER) database (2007 - 2014), aged ≥ 18 years, and diagnosed with a malignant primary head and neck cancer. Incidence trends for stage at presentation was estimated using Joinpoint regression analysis. Binary logistic regression estimated odds of presenting with late-stage disease. The association between health insurance status (private insurance, uninsured and Medicaid), and stage of presentation (AJCC stages I-IV) on the outcomes of interest (overall and disease-specific survival) was estimated using Fine and Gray proportional hazards models, while adjusting for covariates, including age at diagnosis, race/ethnicity, marital status, and tumor site.

Results: The incidence of stage IV head and neck cancer in this subpopulation rose by 1.24% from 2007-2014 (APC=1.24, 95% CI 0.30, 2.20). Patients with Medicaid (aOR=1.59, 95% CI 1.45, 1.74) and who were uninsured (aOR=1.73, 95% CI 1.47, 2.04) were more likely to be diagnosed with advanced-stage (stages III/IV) head and neck cancer. Cancers of the hypopharynx (81%) and oropharynx (83%) were most likely to be diagnosed at an advanced stage. Female patients with Medicaid (aHR=1.47, 95% CI 1.38, 1.56) and who were uninsured (aHR=1.45, 95% CI 1.29, 1.63) were more likely to die from any cause compared to privately insured patients. Medicaid (aHR=1.34, 95% CI 1.24, 1.44) and uninsured (aHR=1.41, 95% CI 1.24, 1.60) patients also had a greater hazard of death from head and neck cancer compared to privately insured patients.

Conclusions: There has been a significant increase in the incidence of advanced-stage presentation for female head and neck cancer patients in the United States since 2007. Patients who are either uninsured or are on Medicaid are more likely to present with late-stage disease and die earlier than those with private insurance. This study illustrates the need to evaluate and address the unique burden of head and neck cancer among females. It is critical that physicians are aware of the trends in head and neck cancer among females and the need for further evaluation or referral of their high-risk patients when concerned.

Abstract A115: Socioeconomic disparities associated with 90-day mortality among patients with head and neck cancer in the United States

Background: There are previous studies on the impact of socioeconomic status on head and neck cancer outcomes, but it is not clear whether these factors are associated with short-term mortality as most studies on risk factors for mortality have focused on long-term mortality and clinical factors. This study aimed to quantify 90-day mortality rates and identify socioeconomic factors associated with 90-day mortality among patients with head and neck cancer.

Methods: This retrospective cohort study included 260,011 patients from the National Cancer Database (2004 to 2014) ≥ 18 years with a diagnosis of head and neck cancer and treated with curative intent with a combination of either surgery, radiation, and/or chemotherapy. Our outcome of interest was any-cause mortality within 90 days of first treatment. The effects of socioeconomic factors on 90-day mortality were estimated using the Cox proportional hazards model with the following adjustments: Heaviside function for time-varying effects and Šidák correction for familywise error (multiple comparisons). A multinomial cumulative logit model estimated the likelihood of higher comorbidity scores in variables of interest.

Results: There were 9,771 deaths within 90 days of treatment, yielding a 90-day mortality rate of 3.8%. Several socioeconomic factors were associated with 90-day mortality. Blacks (aHR = 1.10, 95% CI 1.00, 1.21) and males (aHR = 1.07; 95% CI 1.00, 1.15) were marginally more likely to die within 90 days of treatment. Hazard of 90-day mortality was significantly greater among patients who were uninsured (aHR = 1.71; 95% CI 1.48, 1.99) or insured by Medicaid (aHR = 1.72; 95% CI 1.53, 1.93) or Medicare (aHR = 1.40; 95% CI 1.27, 1.53), compared to those with private insurance. Residence in a zip-code with lower median income was associated with greater hazard of 90-day mortality [(aHR &lt;$30,000 = 1.30; 95% CI 1.18, 1.44); (aHR $30,000 - $34,999 = 1.24; 95% CI 1.13, 1.36); (aHR $35,000 - $45,999 = 1.18; 95% CI 1.08, 1.27)], while farther travel distance for treatment was associated with decreased hazard of 90-day mortality [(aHR 50 - 249.9 miles = 0.86; 95% CI 0.77, 0.97); (aHR &gt;250 miles = 0.70; 95% CI 50, 0.99)]. In addition, farther travel distance for treatment was associated with lower comorbidity scores [(aOR 50 - 249.9 miles = 0.91; 99% CI 0.86, 0.97); (aOR &gt;250 miles = 0.78; 99% CI 0.67, 0.92)].

Conclusions: While the 90-day mortality rate was low among this national cohort of patients with head and neck cancer, there were significant sociodemographic disparities observed. Males, blacks, those uninsured, those with Medicaid or Medicare, and those living in poorer zip codes were more likely to die within 90 days of treatment, highlighting issues associated with access to care. To improve short-term head and neck cancer outcomes, these socioeconomic disparities associated with differing mortality rates among this cancer patient population need to be addressed.

Abstract A121: Effect of state Medicaid expansion status on insurance coverage and stage at diagnosis in head and neck cancer patients

Objective: Access to care is an important issue for head and neck cancer (HNC) patients as HNC is one of the most expensive cancers, particularly for late stage disease. While some data show increased insurance coverage with Medicaid expansion, evidence is limited for impacts on socioeconomic disparities in insurance or on stage at diagnoses. This study aimed to quantify the impact of state Medicaid expansion status on insurance status and stage at diagnosis in HNC patients. Methods: Using a quasi-experimental design, the 2011-2015 Surveillance, Epidemiology, and End Results database was queried for adults with HNC in the United States. Changes in insurance coverage and stage at diagnosis after 2014 in states that expanded Medicaid (EXP) were compared to changes in states that did not expand Medicaid (NEXP). Difference-in-differences analyses were used to assess changes in the percentage of Medicaid coverage, uninsured, and early stage diagnoses in EXP relative to NEXP states. Results: A total of 26,330 HNC cases were identified. In difference-in-difference analyses, we observed an increase in Medicaid insurance in expansion relative to non-expansion states (3.36 percentage points (PP), 95% CI = 1.32, 5.41, p=.001), especially for residents of low income and education counties. We also observed a reduction in uninsured status among HNC patients in low income counties (-4.17 PP, 95% CI = -6.84, -1.51; p=.002). Additionally, we found significant increases among young adults age 18-34 years (17.2 PP, 95% CI – 1.34, 33.10, p=0.034), females (7.54 PP, 95% CI = 2.00, 13.10, p=0.008), unmarried patients (3.83 PP, 95% CI = 0.30, 7.35, p=0.033), and patients with cancer of the lip (13.5 PP, 95% CI = 2.67, 24.30, p=0.015). There was some evidence for greater expansion-associated increases in early stage diagnoses for non-Hispanic blacks (8.53 PP) and other races (20.4 PP) relative to white HNC patients (p=.025). Conclusions: Medicaid expansion is associated with improved insurance coverage for HNC patients, particularly those with low income, and increased early stage diagnoses for young adults and for racial/ethnic minorities. Thus, Medicaid expansion may improve access to care for patients with HNC. Our findings are particularly relevant at a time when there is debate in the United States about healthcare financing, Medicaid, and the Affordable Care Act.

Airborne Aerosol Generation During Endonasal Procedures in the Era of COVID-19: Risks and Recommendations

OBJECTIVE

In the era of SARS-CoV-2, the risk of infectious airborne aerosol generation during otolaryngologic procedures has been an area of increasing concern. The objective of this investigation was to quantify airborne aerosol production under clinical and surgical conditions and examine efficacy of mask mitigation strategies.

STUDY DESIGN

Prospective quantification of airborne aerosol generation during surgical and clinical simulation.

SETTING

Cadaver laboratory and clinical examination room.

SUBJECTS AND METHODS

Airborne aerosol quantification with an optical particle sizer was performed in real time during cadaveric simulated endoscopic surgical conditions, including hand instrumentation, microdebrider use, high-speed drilling, and cautery. Aerosol sampling was additionally performed in simulated clinical and diagnostic settings. All clinical and surgical procedures were evaluated for propensity for significant airborne aerosol generation.

RESULTS

Hand instrumentation and microdebridement did not produce detectable airborne aerosols in the range of 1 to 10 μm. Suction drilling at 12,000 rpm, high-speed drilling (4-mm diamond or cutting burs) at 70,000 rpm, and transnasal cautery generated significant airborne aerosols (P < .001). In clinical simulations, nasal endoscopy (P < .05), speech (P < .01), and sneezing (P < .01) generated 1- to 10-μm airborne aerosols. Significant aerosol escape was seen even with utilization of a standard surgical mask (P < .05). Intact and VENT-modified (valved endoscopy of the nose and throat) N95 respirator use prevented significant airborne aerosol spread.

CONCLUSION

Transnasal drill and cautery use is associated with significant airborne particulate matter production in the range of 1 to 10 μm under surgical conditions. During simulated clinical activity, airborne aerosol generation was seen during nasal endoscopy, speech, and sneezing. Intact or VENT-modified N95 respirators mitigated airborne aerosol transmission, while standard surgical masks did not.

Marital status and suicide as a competing cause of mortality among cancer survivors

e19113

Background: The risk of suicide among cancer survivors more than double that of the general population, highlighting the need to mitigating risk factors for suicide. While several studies have described marital status, a surrogate for social support, as associated with cancer mortality, it is inconclusive whether marital status impacts suicide as a competing cause of cancer mortality. We tested this hypothesis by describing the association of marital status and suicide among survivors of four cancer sites with the highest suicide mortality rates in the United States. Methods: Adult cancer patients were identified from the Surveillance, Epidemiology and End Results database from 2004 to 2016 for four index cancer sites previously identified with highest suicide mortality rates: pancreas, head and neck, lung/bronchus and stomach ( n = 800,798). Cumulative incidence curves stratified by marital status (divorced/separated, widowed, never unmarried, and married/partnered) estimated unadjusted probability of suicide (outcome of interest). A multivariable competing risk proportional hazards model yielded sub-distribution hazard ratios (sdHRs) and 95% confidence intervals (CI) to estimate the association of marital status with suicide for each cancer site, while controlling for clinical and nonclinical factors. Results: Half (50.7%) of the cohort were married/partnered, males (56.8%), and non-Hispanic whites (71.0%). Mean age at diagnosis was 67.3 years. Most patients (60.9%) had cancer in the lung/bronchus, 17.9% head and neck, 13.8% pancreas, and 8.3% stomach. Unadjusted probability of suicide was highest among head and neck cancer survivors (0.3%). In the fully adjusted model, mortality by suicide was more likely among divorced/separated patients vs. married/partnered patients across cancer sites (sdHRhead and neck = 1.81; 95% CI 1.38, 2.37; sdHRlung/bronchus = 1.68; 95% CI 1.28, 2.19; sdHRpancreas = 2.19; 95% CI 1.27, 3.78; and sdHRstomach = 2.38; 95% CI 1.17, 4.58). Additionally, for lung/bronchus cancer, patients who were never married patients were more likely to die by suicide than those married/partnered (sdHRlung/bronchus = 1.47; 95% CI 1.09, 1.98). Conclusions: Marital status is associated with suicide mortality among cancer survivors, and divorced/separated survivors may have greater suicide mortality risks, independent of cancer site. As overall probability of suicide remains low, these findings might help identify cancer survivors who may be candidates for ongoing surveillance and psychosocial support to mitigate suicide mortality risks.
