The impact of distance to facility on treatment modality, short-term outcomes, and survival of patients with HPV-positive oropharyngeal squamous cell carcinoma.

PURPOSE: This study compared treatment and outcomes for patients with HPV-positive oropharyngeal squamous cell carcinoma (OPSCC) based on their travel distance to treatment facility. MATERIALS AND METHODS: Patients with cT1-4, N0-3, M0 HPV-positive OPSCC in the National Cancer Database from 2010 to 2019 were identified and split into four quartiles based on distance to facility, with quartile 4 representing patients with furthest travel distances. Multivariable-adjusted logistic regression and Cox proportional hazards modeling were used to analyze the primary outcome of treatment received, and secondary outcomes of clinical stage, overall survival, surgical approach (i.e., TORS versus other), and 30-day surgical readmissions. RESULTS: 17,207 patients with HPV-positive OPSCC were evenly distributed into four quartiles. Compared to patients in quartile 1, patients in quartile 4 were 40 % less likely to receive radiation versus surgery (OR = 0.60; 95 % CI = 0.54-0.66). Among the patients who received surgery, quartile 4 had a higher odds of receiving TORS treatment compared to quartile 1 (4v1: OR = 2.38; 95 % CI = 2.05-2.77), quartile 2 (4v2: OR = 2.31, 95 % CI = 2.00-2.66), and quartile 3 (4v3: OR = 1.75; 95 % CI = 1.54-1.99). Quartile 4 had a decreased odds of mortality compared to Quartile 1 (4v1: OR = 0.87; 95 % CI = 0.79-0.97). There were no differences among the quartiles in presenting stage and 30-day readmissions. CONCLUSIONS: This study found that patients with furthest travel distance to facility were more often treated surgically over non-surgical management, with TORS over open surgery, and had better overall survival. These findings highlight potential disparities in access to care for patients with HPV-positive OPSCC.

Evaluating human papillomavirus testing, prevalence, and association with prognosis in head and neck squamous cell carcinoma by subsite: A national cancer database study.

PURPOSE: To compare human papillomavirus (HPV) testing, prevalence, and association with prognosis between head and neck squamous cell carcinoma (HNSCC) subsites. MATERIALS AND METHODS: This study utilized the National Cancer Database (NCDB) to identify patients diagnosed with HNSCC between 2010 and 2017. Rates of HPV testing, HPV-positivity, and changes in these rates over time were measured by subsite. The impact of HPV-positivity on overall survival across six head and neck subsites was assessed using multivariable-adjusted Cox proportional hazards analysis. RESULTS: A total of 121,550 patients were included. Of this cohort, 87,575 (72.1%) were tested for HPV, with the oropharynx (55,049/64,158; 85.8%) displaying the highest rates of testing and the sinonasal tract (1519/2853; 53.2%) displaying the lowest testing rates. Of the 86,136 with a definitive result, 46,878 (54.4%) were HPV-positive, with the oropharynx (40,313/54,205; 74.4%) displaying the highest rates of HPV-positivity and the oral cavity (1818/11,505; 15.8%) displaying the lowest. HPV-positive malignancy was associated with significantly improved adjusted overall survival in the oropharynx (HR = 0.42 [95% CI: 0.43-0.47]), oral cavity (HR = 0.86 [95% CI: 0.79-0.95]), sinonasal tract (HR = 0.63 [95% CI: 0.48-0.83]), larynx (HR = 0.78 [95% CI: 0.71-0.87]), and hypopharynx (HR = 0.56 [95% CI: 0.48-0.66]), but not the nasopharynx (HR = 0.93 [95% CI: 0.77-1.14]). CONCLUSION: HPV testing rates were significantly lower in non-oropharyngeal subsites. This is relevant as HPV-associated disease displayed significantly improved overall survival in both the oropharynx and four of five non-oropharyngeal subsites. While validation with prospective studies is necessary, these findings may warrant HPV testing in all HNSCC subsites.

2-Octyl cyanoacrylate to prevent salivary fistula formation following oral cavity microvascular reconstruction: A prospective trial.

BACKGROUND: Salivary fistulas remain a significant problem in patients undergoing major head and neck reconstructive surgery. Surgical sealants have become increasingly used in cutaneous and non-cutaneous wound closure, providing a barrier to fluids/gases and promoting healing. The purpose of this study was to determine the efficacy of a common surgical sealant, 2-Octyl Cyanoacrylate (2-OCA, Dermabond®), in the prevention of salivary fistulas following free flap reconstruction of the oral cavity. METHODS: In this non-randomized, single arm prospective trial, patients undergoing free flap reconstruction of gravity-dependent oral cavity defects were recruited. Application of 2-OCA was performed along flap inset suture lines at the time of surgery. Prospectively collected trial data were propensity score matched to a control cohort to compare outcomes. Data collected include demographics, medical co-morbidities, previous treatments, primary tumor site, and subsites reconstructed. The primary outcome measure was rate of salivary fistula formation. Secondary outcomes were time to development of leak and percentage of patients tolerating oral feeding at one month post-operatively. RESULTS: In the 46 propensity score matched pairs, eight (17.4%) out of 46 patients in the 2-OCA prospective cohort and seven (15.2%) out of 46 patients in the control cohort developed postoperative salivary fistulas within the one-month study interval (p = 1.00). The average time to postoperative leak in the 2-OCA group was 12.5 days versus 7.1 days in the control cohort (p = 0.10). In the 2-OCA group, 30 (65.2%) patients were tolerating regular diet at one month post-operatively compared to 33 (71.7%) in the control cohort (p = 0.65). CONCLUSION: Salivary fistula rates after application of a 2-OCA surgical sealant were not improved compared to a control cohort in this single institutional trial. There are several surgical sealants available, each with varying elasticity and adhesiveness. Future studies are needed to identify surgical sealants that are able to provide sufficient strength and adhesion to seal closures and combat corrosive saliva, but elastic enough to handle motion related tension during swallowing and post-operative movements in the head and neck.

Circulating Tumor HPV DNA in Patients With Head and Neck Carcinoma: Correlation With HPV Genotyping.

Circulating tumor human papillomavirus DNA (ctHPVDNA) testing using digital-droplet polymerase chain reaction (PCR) detects fragments of tumor-modified human papillomavirus (HPV) in the plasma of patients with HPV-associated head and neck squamous cell carcinomas (HNSCCs). Its impact on tumor surveillance and primary diagnosis is limited by unresolved issues relating to sensitivity and specificity. The study population consisted of patients with HNSCC who had undergone ctHPVDNA testing. HPV status was determined by p16 immunohistochemistry and PCR-HPV genotyping on the tumor samples. For discrepant cases (HPV-positive/ctHPVDNA-negative), HPV status was confirmed by RNA in situ hybridization and, when possible, targeted single-nucleotide polymorphisms genotyping. A total of 167 patients had ctHPVDNA testing, and 141 tumors were HPV positive by p16 immunohistochemistry and PCR genotyping. Genotypes included types 16 (91.5%), 33 (4.3%), 35 (2.1%), and 18 (2.1%). ctHPVDNA was detected in 133 (94.3%) of HPV-positive HNSCCs but in none of the HPV-negative HNSCCs. Four of the 5 p16-positive cases that were negative by PCR and ctHPVDNA were positive by RNA in situ hybridization, and in 2 of these cases, rare high-risk genotypes were identified. ctHPVDNA had a sensitivity of 91.7%, specificity of 100%, positive predictive value of 100%, and negative predictive value of 63.6%. The likelihood that patients with HPV-positive HNSCC have detectable ctHPVDNA is high. Non-HPV16 genotypes contribute to discrepancies but only in a small subset of cases. This finding validates ongoing efforts to use ctHPVDNA as a surveillance tool, and even as a primary diagnostic assay in patients presenting with masses in the neck and/or oropharynx.

Treatment discordance in the utilization of neck dissection for stage I-II supraglottic tumors.

BACKGROUND: In 2018, the National Comprehensive Cancer Network treatment guidelines began recommending the use of neck dissection during surgical management of stage I-II supraglottic laryngeal squamous cell carcinoma (LSCC). METHODS: Trends and factors associated with the use of neck dissection during larynx-preserving surgery for patients with cT1-2, N0, M0 supraglottic LSCC in the National Cancer Database (2004-2020) were evaluated using multivariable-adjusted logistic regression. RESULTS: Of the 2080 patients who satisfied study eligibility criteria, 633 (30.4%) underwent neck dissection. Between 2018 and 2020, the rate of neck dissection was 39.0% (114/292). After multivariable adjustment, academic facility type, undergoing biopsy prior to surgery, and more radical surgery were significant predictors of receiving neck dissection. CONCLUSIONS: The results of this national analysis suggest that the utilization of guideline-concordant neck dissection for management of stage I-II supraglottic LSCC remains low and highlight the need to promote the practice of neck dissection for this patient population.

The Impact of Hospital Safety-Net Burden Status on Patients with HPV-Positive Oropharyngeal Cancer.

OBJECTIVES: The objective of this study was to compare treatment characteristics and outcomes between patients with HPV-positive oropharyngeal squamous cell carcinoma (OPSCC) treated at hospitals of varying safety-net burden status. METHODS: Patients with cT1-4, N0-3, M0 HPV-positive OPSCC who underwent definitive surgery or radiation were included. Patients were grouped based on their treating hospital safety-net burden status, defined as the percentage of uninsured and Medicaid-insured patients with OPSCC treated at the facility and stratified as low burden (LBH: 0-25th percentile), medium burden (MBH: 25th-75th percentile), or high burden (HBH: 75th-100th percentile). The primary outcome was primary treatment with surgery versus radiation, evaluated with multivariable-adjusted logistic regression. Secondary outcomes included TORS versus open surgical approach, and overall survival evaluated with Cox proportional hazards analysis. RESULTS: Of the 19,810 patients with cT1-4, N0-3, M0 HPV-positive OPSCC included in this study, 4921 (24.8%) were treated at LBH, 12,201 (61.6%) were treated at MBH, and 2688 (13.6%) were treated at HBH. In multivariable-adjusted analysis, compared with treatment at LBH, treatment at HBH was associated with more frequent radiation over surgical treatment (OR: 1.26, 95% CI: 1.12-1.40, p < 0.001). For patients undergoing surgery, patients at HBH had less frequent transoral robotic surgery (OR: 0.30, 95% CI 0.24-0.38, p < 0.001) compared with patients treated at LBH. Overall survival of patients treated at HBH was worse than that of patients treated at LBH (HR: 1.27, 95% CI 1.13-1.43, p < 0.001). CONCLUSION: These findings highlight underlying disparities at higher safety-net burden facilities that impact patterns of care and outcomes for patients with OPSCC.

5-Aminolevulinic Acid Fluorescence-Guided Surgery in Head and Neck Squamous Cell Carcinoma.

OBJECTIVES: To determine the utility of 5-aminolevulinic acid (5-ALA) fluorescence for resection of head and neck carcinoma. METHODS: In this prospective pilot trial, 5-ALA was administered as an oral suspension 3-5 h prior to induction of anesthesia for resection of head and neck squamous cell carcinoma (HNSCC). Following resection, 405 nm blue light was applied, and fluorescence of the tumor as well as the surgical bed was recorded. Specimen fluorescence intensity was graded categorically as none (score = 0), mild (1), moderate (2), or robust (3) by the operating surgeon intraoperatively and corroborated with final pathologic diagnosis. RESULTS: Seven patients underwent resection with 5-ALA. Five (83%) were male with an age range of 33-82 years (mean = 60). Sites included nasal cavity (n = 3), oral cavity (n = 3), and the larynx (n = 1). All specimens demonstrated robust fluorescence when 5-ALA was administered 3-5 h preoperatively. 5-ALA fluorescence predicted the presence of perineural invasion, a positive margin, and metastatic lymphadenopathy. Two patients had acute photosensitivity reactions, and one patient had a temporary elevation of hepatic enzymes. CONCLUSIONS: 5-ALA induces robust intraoperative fluorescence of HNSCC, capable of demonstrating a positive margin, perineural invasion, and metastatic nodal disease. Although no conclusions are there about the safety of this drug in the head and neck cancer population, our study parallels the extensive safety data in the neurosurgical literature. Future applications may include intraoperative assessment of margin status, diagnostic accuracy, and impacts on survival. LEVEL OF EVIDENCE: 4 Laryngoscope, 134:741-748, 2024.

Salvage surgery for recurrent or residual hypopharyngeal squamous cell carcinoma: A systematic review.

BACKGROUND: This systematic review aggregates the data of studies that include site-specific analyses of patients undergoing salvage surgery for residual or recurrent hypopharyngeal squamous cell carcinoma. METHODS: The primary outcomes are disease-free, disease-specific, and overall survival (DFS, DSS, and OS, respectively). Secondary outcomes include complications and postoperative feeding requirements. RESULTS: Fifteen studies met the inclusion criteria with a total of 442 patients. Two-year DFS is reported from 30.0 to 50.0% and 5-year DFS ranges from 15.0 to 57.1%. Five-year DSS ranges from 28.0 to 57.1%. Two-year OS ranges from 38.8 to 52.0% and 5-year OS ranges from 15.5 to 57.1%. Complications include pharyngocutaneous fistula (0.0-71.4%), carotid artery rupture (2.9-13.3%), and stomal stenosis (4.2-20.0%). Complete oral feeding achieved following surgery ranges from 61.9 to 100.0%, while complete gastrostomy tube dependence ranges from 0.0 to 28.6%. CONCLUSIONS: Salvage surgery for residual or recurrent hypopharyngeal squamous cell carcinoma has a relatively high complication rate and should be offered to patients with the understanding of a guarded prognosis.

Early feeding after free flap reconstruction of the oral cavity: A systematic review and meta-analysis.

BACKGROUND: Traditionally, patients undergoing free flap reconstruction for oral cavity defects have been given nothing by mouth for 6-14 days post-operatively due to concern for orocutaneous fistula development. METHODS: Multiple databases were screened for studies assessing the rate of orocutaneous fistula formation in early (≤5 days) versus late (>5 days) feeding groups following oral cavity free flap reconstruction. Fixed- and random-effects meta-analyses were used. RESULTS: One randomized controlled trial, one prospective cohort, and three retrospective cohort studies were included. The early feeding group displayed no significant increase in orocutaneous fistula formation (RD = -0.02, p = 0.06) or free flap failure (RD = -0.01, p = 0.39), with a significantly shorter hospital length of stay (mean difference [days] = -2.43, p < 0.01). CONCLUSIONS: While further prospective trials are necessary, initiation of oral intake before post-operative day 5 may be appropriate in properly selected patients following oral reconstruction.

Head and Neck Cancer Patient Population, Management, and Oncologic Outcomes from the COVID-19 Pandemic.

The COVID-19 pandemic precipitated drastic changes in cancer care. Its impact on the U.S. head and neck cancer population has yet to be fully understood. This study aims to understand the impact of pandemic-related changes on the head and neck cancer population. An observational study of head and neck cancer patients at a single institution during the spring of 2020 and 2019 was performed. Clinical characteristics and survival outcomes were analyzed. In 2020, 54 head and neck cancer patients were evaluated in the department of radiation oncology vs. 74 patients seen in 2019; 42% of the patients were female in 2019 versus 24% in 2020 (p = 0.036). The median follow-up time was 19.4 and 31 months for 2020 and 2019, respectively. After adjusting for stage, the relapse-free survival probability at 6 and 12 months was 79% and 69% in 2020 vs. 96% and 89% in 2019, respectively (p = 0.036). There was no significant difference in the overall survival, with 94% and 89% in 2020 and 2019, respectively (p = 0.61). Twenty-one percent of patients received induction chemotherapy in 2020 versus 5% in 2019 (p = 0.011); significantly more treatment incompletions occurred in 2020, 9% vs. 0% in 2019 (p = 0.012). Moreover, the stage-adjusted RFS differed between cohorts, suggesting head and neck cancer patients seen during the initial wave of COVID-19 may experience worse oncologic outcomes.

Adjuvant Reirradiation With Proton Therapy in Head and Neck Squamous Cell Carcinoma.

Purpose: For patients with head and neck squamous cell carcinoma (HNSCC), locoregional failure and second primary tumors are common indications for adjuvant reirradiation (re-RT). Given an absence of clear consensus on the role of adjuvant re-RT, we sought to assess histopathologic risk factors of patients with HNSCC and their resulting outcomes after adjuvant re-RT with proton therapy. Methods and Materials: We conducted a retrospective analysis of patients with HNSCC who underwent salvage surgery at our institution followed by adjuvant re-RT with proton therapy over 1.5 years. All included patients received prior radiation therapy. The Kaplan-Meier method was used to evaluate locoregional recurrence-free survival and overall survival. Results: The cohort included 22 patients, with disease subsites, including oropharynx, oral cavity, hypopharynx, larynx, and nasopharynx. Depending on adverse pathologic features, adjuvant re-RT to 66 Gy (32% of cohort) or 60 Gy (68%), with (59%) or without (41%) concurrent systemic therapy was administered. The majority (86%) completed re-RT with no reported treatment delay; 3 patients experienced grade ≥3 acute Common Terminology Criteria for Adverse Events toxicity and no patient required enteral feeding tube placement during re-RT. Median follow-up was 21.0 months (IQR, 11.7-25.2 months). Five patients had biopsy-proven disease recurrences a median of 5.9 months (IQR, 3.8-9.7 months) after re-RT. Locoregional recurrence-free survival was 95.2%, 70.2%, 64.8% at 6, 12, and 24 months, respectively. OS was 100%, 79.2%, and 79.2% at 6, 12, and 24 months, respectively. Four patients had osteoradionecrosis on imaging a median of 13.2 months (IQR, 8.7-17.4 months) after re-RT, with 2 requiring surgical intervention. Conclusions: Adjuvant re-RT for patients with HNSCC was well-tolerated and offered reasonable local control in this high-risk cohort but appears to be associated with a risk of osteoradionecrosis. Additional study and longer follow-up could help define optimal patient management in this patient population.

Utility of TTMV-HPV DNA in resolving indeterminate findings during oropharyngeal cancer surveillance.

OBJECTIVES: Clinical and imaging examinations frequently have indeterminate results during cancer surveillance, which can lead to overtreatment and cause psychological and financial harm to the patient. This study addresses the critical need to enhance diagnostic precision and decision-making in the management of HPV-associated oropharyngeal cancer. This study evaluated the utility of tumor tissue-modified viral (TTMV)-HPV DNA to resolve indeterminate disease status following definitive treatment for HPV-associated oropharyngeal cancer. MATERIALS AND METHODS: In this retrospective cohort, patients treated for HPV-associated oropharyngeal cancer at eight U.S. institutions and who received one or more TTMV-HPV DNA tests during post-treatment surveillance between February 2020 and January 2022 were included. RESULTS: Among 543 patients, 210 patients (38.7%; 210/543) experienced one or more clinically indeterminate findings (CIFs) during surveillance, with 503 CIFs recorded. Of those patients with an "indeterminate" disease status at a point during surveillance, 79 were associated with contemporaneous TTMV-HPV DNA testing. TTMV-HPV DNA testing demonstrated high accuracy (97.5%; 77/79) in correctly determining recurrence status. Patients whose disease status was "indeterminate" at the time of a positive TTMV-HPV DNA test were clinically confirmed to recur faster than those whose disease status was "no evidence of disease." Only 3% of patients (17/543) experienced indeterminate TTMV-HPV DNA tests during surveillance. Discordance between TTMV-HPV DNA tests and clinical results was minimal, with only 0.6% (3/543) of patients showing positive tests without recurrence. CONCLUSION: Our findings support the utility of circulating TTMV-HPV DNA in resolving indeterminate disease status and informing the subsequent clinical course.

Pulse granuloma presenting as a lateral neck mass: An unusual presentation of a fourth branchial cleft fistula.

BACKGROUND: The pulse granuloma (PG) is believed to represent a distinctive foreign body reaction to ingested particles of legumes. Its presentation in the neck is entirely unexpected. METHODS: A woman presented with a mass of the lower neck that recurred following incision and drainage. The recurrent mass was found to be associated with an open sinus tract at the apex of the left pyriform sinus. The opening of the sinus tract was closed and the cyst was removed. RESULTS: Histologic examination of the neck mass showed vegetable material with an associated granulomatous reaction known as PG. CONCLUSIONS: The documentation of a PG arising in the neck would seemingly discredit the legume theory, but it only further supports it. Its association with a fourth branchial cleft cyst provides evidence for the existence of the complete fourth branchial cleft fistula with seeding of ingested material through sinus tract opening.

The impact of undergoing surgical margin evaluation during endoscopic surgery for early-stage laryngeal squamous cell carcinoma.

BACKGROUND: The impact of evaluating versus not evaluating surgical margins for early-stage laryngeal squamous cell carcinoma (LSCC) has not been evaluated. METHODS: Overall survival was compared between patients who underwent endoscopic surgery for cT1-2, N0, M0 LSCC and had surgical margins evaluated versus not evaluated versus unevaluable in the National Cancer Database (2010-2019) using multivariable-adjusted Cox proportional hazards analyses. RESULTS: 7597 patients met study eligibility criteria. 4123 (54.3%) patients underwent margin evaluation, 1631 (21.5%) did not undergo margin evaluation, and 1843 (24.3%) had unevaluable margins. Patients undergoing margin evaluation had better overall survival than patients who did not undergo margin evaluation (HR: 0.88, 95% CI: 0.78-1.00, p = 0.044) and patients with unevaluable margins (HR: 0.88, 95% CI: 0.78-0.98, p = 0.021). Patients undergoing margin evaluation received significantly less adjuvant radiation. CONCLUSIONS: Surgical margin evaluation is an important prognostic factor for patients receiving endoscopic surgery for early-stage LSCC and should be conducted whenever possible.

Clinical and Therapeutic Considerations for Older Adults with Head and Neck Cancer.

Approximately 30% of patients with head and neck squamous cell carcinoma (HNSCC) are at least 70 years of age, and this percentage is expected to increase as the population increases and lives longer. Elderly patients are underrepresented in head and neck oncology clinical trials, and there is minimal evidence on the management of HNSCC for this population. Subsequently, despite their best intentions, physicians may unknowingly recommend an ill-suited course of therapy, which may result in suboptimal oncological or functional outcomes or adverse events. Surgical approaches have the potential to carry a higher risk of morbidity and mortality in older adults, especially in patients with multiple comorbidities. Definitive radiation therapy treatment in patients with HNSCC frequently involves 7 weeks of daily radiation, sometimes with concurrent chemotherapy, and this demanding treatment can be difficult for older adult patients, which may lead to treatment interruptions, potential removal of concurrent systemic therapy, compromised outcomes, and diminished quality of life. There are clinical trials currently underway investigating altered fractionation regimens and novel, less toxic systemic treatments in this population. This review provides an overview of how best to approach an older adult with HNSCC, from initial work-up to treatment selection.

Evaluating depth of invasion across oral cavity subsites as part of the AJCC 8th edition T staging criteria for oral cavity squamous cell carcinoma.

BACKGROUND: The prognostic impact of depth of invasion (DOI) in American Joint Committee on Cancer 8th edition TNM staging for oral cavity squamous cell carcinoma (OCSCCa) across oral cavity subsites is unknown. METHODS: Overall survival of patients with pT1-4a OCSCCa in the National Cancer Database (2010-2017), stratified by tumor size and DOI across eight oral cavity subsites, was evaluated using multivariable-adjusted Cox proportional hazards modeling. RESULTS: When stratified by tumor size ≤2 cm and >2 cm, DOI >5 mm and DOI >10 mm were only associated with worse overall survival, respectively, for tumors of the oral tongue (Tumor size ≤2 cm, DOI >5 mm v DOI ≤5 mm: HR: 1.31, 95% CI: 1.12-1.53, p < 0.001; Tumor size >2 cm, DOI >10 mm v DOI ≤10 mm: HR: 1.15, 95% CI: 1.01-1.30, p = 0.03). DOI >5 mm and DOI >10 mm was not prognostic for any other tumor location. CONCLUSIONS: These findings suggest that the current staging schema for DOI in OCSCCa may not be prognostic across all oral cavity subsites.

Free Tissue Transfer for Skull Base Osteoradionecrosis: A Novel Approach in the Endoscopic Era.

OBJECTIVES: Osteoradionecrosis (ORN) of the skull base and craniovertebral junction is a challenging complication of radiation therapy (RT). Severe cases often require surgical intervention through a multi-modal approach. With the evolution in endoscopic surgery and advances in skull base reconstruction, there is an increasing role for microvascular free tissue transfer (MFTT). We describe an endoscopic-assisted approach for the management of ORN of the skull base using fascia lata for MFTT. STUDY DESIGN: Retrospective case series. METHODS: Between 2017 and 2021, a review of all cases in which fascia lata MFTT was utilized for skull base ORN was performed. Patient demographics, preoperative characteristics, and postoperative outcomes with long-term follow-up were reviewed. RESULTS: Five patients were identified. Mean duration to onset of ORN was 17 months following RT. A trial of antibiotics, hyperbaric oxygen (HBO), and/or limited debridement was attempted without success. Refractory pain and progressive osteomyelitis were unifying symptoms. All patients underwent endoscopic debridement of the affected region of ORN prior to MFTT. Vascularized fascia lata was inset through a combined endonasal and transoral corridor. There was improvement in chronic pain in the postop setting with no patients requiring continued antibiotics or HBO therapy. Mean post-op follow-up was 23 months. CONCLUSIONS: With continued evolution in endoscopic, minimally invasive approaches, there is an expanding indication for early surgical management in refractory ORN. Fascia lata MFTT is a novel and effective strategy for the management of ORN of the skull base and upper cervical spine with excellent postoperative outcomes and limited patient morbidity.

Neutrophil-to-lymphocyte ratio as a predictor of surgical outcomes in head and neck cancer.

BACKGROUND: Neutrophil-to-lymphocyte ratio (NLR) is a biomarker of systemic inflammation that is associated with adverse oncologic and surgical outcomes. We investigated the use of NLR as a prognostic indicator of complications of head and neck cancer (HNC) surgeries. METHODS: We conducted a retrospective study of 11 187 Veterans who underwent HNC surgery between 2000 and 2020. We calculated preoperative NLR values and fit logistic regression models adjusting for potential confounding factors, comparing high-NLR patients to low-NLR patients. RESULTS: The cohort had a median age of 63 and was 98% men. High-NLR patients had increased odds of 30-day mortality (p < 0.001), having 1+ perioperative complications (p < 0.001), sepsis (p = 0.03), failure to wean from mechanical ventilation (p = 0.04), pneumonia (p < 0.001), and pulmonary embolism (p = 0.02) compared with low-NLR patients. CONCLUSION: NLR was a robust, independent predictor of 30-day mortality, having 1+ surgical complications, sepsis, failure to wean from mechanical ventilation, pneumonia, and pulmonary embolism.

High Failure Rates in Young Nonsmoker Nondrinkers With Squamous Cell Carcinoma of the Oral Tongue.

OBJECTIVE(S): There has been a disproportionate increase in the incidence of young patients with squamous cell carcinoma of the oral tongue (SCCOT). The purpose of this study was to compare young patients to older patients with SCCOT without prior drinking or smoking history as this population is poorly characterized in the literature. METHODS: A retrospective review of patients presenting to our institution with SCCOT was performed. The clinical and pathologic characteristics, as well as, outcomes were compared between younger patients (age ≤45) and older patients (age >45). Outcome analysis was performed using Kaplan Meier method. Multivariable Cox proportional hazard models were performed for age and stage. RESULTS: Eighty-two patients (38 young, 44 old) were included in this study. Median follow-up was 29.4 months. When compared to the older cohort (age >45), the younger cohort (age ≤45) demonstrated lower rates of 5-year locoregional control (LC) (79.6% vs. 52.5%, p = 0.043) and distant metastasis-free survival (88.1% vs. 61.8%, p = 0.006). Both cohorts demonstrated similar overall survival rates (55.5% vs. 58.1%) and disease-specific survival (66.2% vs. 58.1%). Of patients experiencing locoregional failure with available radiation therapy plans and PET scans in younger cohorts (n = 7), 100% demonstrated in-field failures. Multivariable Cox proportional hazards demonstrated age was an independent predictor of DMFS (p = 0.004) and the advanced stage was a predictor of DSS (p = 0.03). CONCLUSIONS: Young, nondrinker, nonsmokers with SCCOT demonstrate high rates of locoregional recurrence, distant metastasis, and in-field failures. Future studies are warranted to determine underlying mechanisms driving pathogenesis in this unique cohort. LEVEL OF EVIDENCE: 3 Laryngoscope, 133:1110-1121, 2023.
