RESUMO
BACKGROUND: Radiotherapy, along with laser surgery, is considered a standard treatment option for patients with early glottic squamous cell cancer (SCC). Historically, patients have received complete larynx radiotherapy (CL-RT) due to fear of swallowing and respiratory laryngeal motion and this remains the standard approach in many academic institutions. Local control (LC) rates with CL-RT have been excellent, however this treatment can carry significant toxicities include adverse voice and swallowing outcomes, along with increased long-term risk of cerebrovascular morbidity. A recent retrospective study reported improved voice quality and similar local control outcomes with focused vocal cord radiotherapy (VC-RT) compared to CL-RT. There is currently no prospective evidence on the safety of VC-RT. The primary objective of this Bayesian Phase II trial is to compare the LC of VC-RT to that of CL-RT in patients with T1N0 glottic SCC. METHODS: One hundred and fifty-five patients with T1a-b N0 SCC of the true vocal cords that are n ot candidate or declined laser surgery, will be randomized in a 1:3 ratio the control arm (CL-RT) and the experimental arm (VC-RT). Randomisation will be stratified by tumor stage (T1a/T1b) and by site (each site will be allowed to select one preferred radiation dose regimen, to be used in both arms). CL-RT volumes will correspond to the conventional RT volumes, with the planning target volume extending from the top of thyroid cartilage lamina superiorly to the bottom of the cricoid inferiorly. VC-RT volumes will include the involved vocal cord(s) and a margin accounting for respiration and set-up uncertainty. The primary endpoint will be LC at 2-years, while secondary endpoints will include patient-reported outcomes (voice impairment, dysphagia and symptom burden), acute and late toxicity radiation-induced toxicity, overall survival, progression free survival, as well as an optional component of acoustic and objective measures of voice analysis using the Consensus Auditory-Perceptual Evaluation of Voice. DISCUSSION: This study would constitute the first prospective evidence on the efficacy and safety of VC-RT in early glottic cancer. If positive, this study would result in the adoption of VC-RT as standard approach in early glottic cancer.

BACKGROUND: To the authors' knowledge, the question of whether human papillomavirus (HPV) infection is associated with outcomes in patients with sinonasal squamous cell carcinoma (SNSCC) is not well studied at this time. In the current study, the authors investigated patterns of HPV testing and its association with survival in patients with SNSCC using the National Cancer Data Base. METHODS: The authors selected all SNSCC cases diagnosed between 2010 and 2016. HPV testing practices, clinicodemographic factors, treatments, and survival were analyzed. Multivariable Cox regression and propensity score-matched survival analyses were performed. RESULTS: A total of 6458 SNSCC cases were identified. Of these, only 1523 cases (23.6%) were tested for HPV and included in the current study. The median patient age was 64 years and the majority had advanced stage tumors (overall AJCC stage III-IV, 721 patients; 62.1%). HPV-positive SNSCC comprised 31.5% (447 of 1418 cases) of the final study cohort. Among 15 hospitals that routinely tested nonoropharyngeal SCCs for HPV, the percentage of HPV-positive SNSCCs was smaller (24.6%; P = .04). Patients with HPV-positive SNSCC were younger (aged 60 years vs 65 years; P < .001), with tumors that were more likely to be high grade (55.3% vs 41.7%; P < .001), and attributed to the nasal cavity (62.2% vs 44.0%; P < .001). HPV-positive SNSCC was associated with significantly improved overall survival in multivariable regression analysis (hazard ratio, 0.45; 95% CI, 0.28-0.72 [P = .001]) and propensity score-matched (hazard ratio, 0.61; 95% CI, 0.38-0.96 [P = .03]) analyses controlling for clinicodemographic and treatment factors. CONCLUSIONS: Currently, only a minority of patients with SNSCC are tested for HPV. However, a sizable percentage of SNSCC cases may be HPV related; furthermore, HPV-positive SNSCC is associated with improved overall survival. Routine HPV testing may be warranted in patients with SNSCC.

We report an evidence-based management algorithm for benign lymphoepithelial cysts (BLEC) of the parotid glands in HIV patients based on long-term outcomes after radiation therapy. From 1987 to 2013, 72 HIV-positive patients with BLEC of the parotid glands treated at our institutions were identified and their medical records were reviewed and analyzed. The primary endpoint of our study was to determine a dose response in HIV patients with BLEC. In group A (≤18 Gy), which received a median dose of 10 Gy (8-18), overall response (OvR), complete response (CR), partial response (PR), and local failure (LF) was experienced by 7, 7, 0, and 93 %, respectively. In group B (≥22.5 Gy), which received a median dose of 24 Gy (22.5-30), OvR, CR, PR, and LF was experienced by 88, 65, 23, and 12 %. Logistic regression revealed that higher dose (≥22.5 Gy) predicted for cosmetic control (p = 0.0003). Multiple regression analysis revealed higher dose predicted for cosmetic control (p = 0.0001) after adjusting for confounding variables (age, gender, race, HAART use, BLEC duration, and fractionation size). No patients in either group experienced RTOG grade ≥3 toxicities. A radiation dose of 24 Gy delivered in 12-16 fractions of 1.5-2 Gy per fraction provides long-term cosmetic control in HIV-positive patients with BLEC of the parotid glands.

Surveillance for survivors of head and neck cancer (HNC) is focused on early detection of recurrent or second primary malignancies. After initial restaging confirms disease-free status, the use of surveillance imaging for asymptomatic patients with HNC is controversial. Our objective was to comprehensively review literature pertaining to imaging and biomarker surveillance of asymptomatic patients treated for head and neck squamous cell carcinoma and to convene a multidisciplinary expert panel to provide appropriate use criteria for surveillance in representative clinical scenarios. The evidence base for the appropriate use criteria was gathered through a librarian-mediated search of literature published from 1990 to 2022 focused on surveillance imaging and circulating tumor-specific DNA for nonmetastatic head and neck squamous cell carcinoma using MEDLINE (Ovid), Embase, Web of Science Core Collection, and the Cochrane Central Register of Controlled Trials. The systematic review was reported according to PRISMA guidelines. Using the modified Delphi process, the expert panel voted on appropriate use criteria, providing recommendations for appropriate use of surveillance imaging and human papillomavirus (HPV) circulating tumor DNA. Of 5178 studies identified, 80 met inclusion criteria (5 meta-analyses/systematic reviews, 1 randomized control trial, 1 post hoc analysis, 25 prospective, and 48 retrospective cohort studies [with ≥50 patients]), reporting on 27,525 patients. No large, randomized, prospective trials examined whether asymptomatic patients who receive surveillance imaging or HPV circulating tumor DNA monitoring benefit from earlier detection of recurrence or second primary tumors in terms of disease-specific or quality-of-life outcomes. In the absence of prospective data, surveillance imaging for HNC survivors should rely on individualized recurrence-risk assessment accounting for initial disease staging, HPV disease status, and tobacco use history. There is an emerging surveillance role for circulating tumor biomarkers.

Background: Patients with head and neck cancer (HNC) often experience high symptom burden leading to lower quality of life (QoL). Objective: This study aims to conceptually model optimal cutpoint by examining where total number of patient-reported symptoms exceeds patients' coping capacity, leading to a decline in QoL in patients with HNC. Methods: Secondary data analysis of 105 individuals with HNC enrolled in a clinical usefulness study of the NYU Electronic Patient Visit Assessment (ePVA)©, a digital patient-reported symptom measure. Patients completed ePVA and European Organization for Research and Treatment of Cancer (EORTC©) QLQ-C30 v3.0. The total number of patient-reported symptoms was the sum of symptoms as identified by the ePVA questionnaire. Analysis of variance (ANOVA) was used to define optimal cutpoint. Results: Study participants had a mean age of 61.5, were primarily male (67.6%), and had Stage IV HNC (53.3%). The cutpoint of 10 symptoms was associated with significant decline of QoL (F= 44.8, P<.0001), dividing the population into categories of low symptom burden (< 10 symptoms) and high symptom burden (≥ 10 symptoms). Analyses of EORTC© function subscales supported the validity of 10 symptoms as the optimal cutpoint (Physical: F=28.3, P<.0001; Role: F=21.6, P<.0001; Emotional: F=9.5, P=.003; Social: F=33.1, P<.0001). Conclusions: In HNC, defining optimal cutpoints in the total number of patient-reported symptoms is feasible. Implications for Practice: Cutpoints in the total number of patient-reported symptoms may identify patients experiencing a high symptom burden from HNC. Foundational: Using optimal cutpoints of the total number of patient-reported symptoms may help effectively align clinical resources with patients' symptom burden.
RESUMO
BACKGROUND: Oral mucositis (OM) is a significant toxicity of induction chemotherapy for locally advanced head and neck cancer (LAHNC). The safety and tolerability of AG013, an oral rinse containing recombinant Lactococcus lactis secreting mucosal protectant human trefoil factor 1 (hTFF1), was evaluated in a phase 1b study in LAHNC subjects who received induction with cisplatin, 5-fluorouracil, with or without docetaxel. Preliminary efficacy data were also obtained. METHODS: A total of 25 of 52 LAHNC subjects who were followed during induction cycle 1 developed ulcerative oral mucositis (UOM; World Health Organization grade > 2) and were randomized to AG013:placebo (5:2 ratio) for cycle 2. Dosing schedules of 1, 3, or 6 times daily were evaluated (2 × 10(11) , 6 × 10(11) , and 1.2 × 10(12) colony forming units per day, respectively). OM was evaluated daily from cycle 2, day 1 through 14, using World Health Organization criteria. Pharmacokinetic assessment was also conducted. RESULTS: AG013 bacteria were not detected in blood. Oral live AG013 bacterial and hTFF1 levels in saliva and oral mucosa were equivalent among treatment groups. The most frequently occurring adverse events were nausea, oral pain, fatigue, diarrhea, and mucosal inflammation. Only 12% (3 of 25 adverse events), mainly nausea, were attributed to the investigational medicinal product: AG013 or placebo. Efficacy analysis showed a 35% reduction in percentage of days with UOM in AG013-subjects versus placebo. All placebo subjects experienced ≥ 2 days of UOM, whereas 29% of AG013 subjects had UOM for 0 or 1 day. AG013 use resulted in fewer unscheduled office and emergency room visits. No differences were noted in mouth and throat soreness, opioid use, or gastrostomy tube placement. CONCLUSIONS: AG013 was safe and well tolerated. Preliminary efficacy data support further study.

BACKGROUND: The aim of this study was to compare intensity-modulated radiation therapy (IMRT) vs. 2D and 3D radiotherapy (RT) in the treatment of T1 glottic squamous cell carcinoma in an effort to highlight the advantages of IMRT in this particular clinical situation. CASE REPORT: We present the case of an 82-year-old female patient with T1 left true vocal cord squamous cell carcinoma and complete occlusion of the left carotid artery resulting in multiple strokes. The patient underwent definitive RT with 63 Gy (28 × 2.25 Gy). 3 plans were generated: 2D RT, 3D RT, and IMRT. The right carotid artery (Rt.CA) mean dose was 865, 2,065, and 4,268 cGy for IMRT, 3D RT, and 2D RT, respectively. The inferior pharyngeal constrictor (IPC) mean dose was 5,341, 6,456, and 6,451 cGy for IMRT, 3D RT, and 2D RT, respectively. IMRT provided the best homogeneity but at a higher cost and with prolonged treatment time. CONCLUSION: IMRT provided the finest planning target volume coverage with minimal Rt.CA and IPC doses. IMRT is recommended in certain clinical scenarios which are not manageable with other techniques.

PURPOSE: Aim of this study was to evaluate the impact of computed tomography (CT)-based simulation and planning on early glottic cancer outcomes and toxicity. METHODS: This is a single-institution retrospective study of 253 patients with T1-2 glottic cancer who underwent radiation therapy (RT) from January 1998-2010. Group A (80%) underwent 2-dimensional RT (2DRT) and group B (20%) 3-dimensional RT (3DRT). 76% of patients in group A and 84% in group B had T1 cancer. The median dose and fraction size were 63 Gy and 2.25 Gy, respectively. RESULTS: With a median follow-up of 83, 93, and 30 months for the whole cohort, group A and B, respectively, the loco-regional control (LRC) was 97.6%. The rate of LRC for T1 disease was 99.5% and for T2 disease 91%. According to the RT modality, rates of LRC were 99.4 and 100% in groups A and B for T1, and 89.8 and 100% for T2. Long-term toxicity was negligible in both groups. Kaplan-Meier Curve showed the 5-year cause-specific survival to be 100%. Chi-square and multivariate analysis tests showed a significant relationship between CT simulation (3DRT) and LRC (p < 0.0001). CONCLUSION: CT-based simulation and planning provided better LRC and less acute side effects compared to 2DRT.

BACKGROUND: The present study characterizes national trends in the utilization of adjuvant chemotherapy to treat salivary gland malignancies. METHODS: The National Cancer Database was queried for salivary gland malignancies treated by surgery with radiation in 2004-2019. Proportions of patients receiving adjuvant chemotherapy over the study period were analyzed by linear regression. The impact of chemotherapy on overall survival was assessed using Kaplan-Meier and Cox proportional hazards analyses. RESULTS: Among 15 965 patients meeting inclusion criteria, 2355 (14.8%) received adjuvant chemotherapy. Chemotherapy utilization significantly increased from 4.9% to 16.5% over the study period (p < 0.001). No survival benefit was observed with adjuvant chemotherapy on propensity score-matched Kaplan-Meier analysis (HR: 0.98; 95% CI: 0.86-1.11; p = 0.72) or multivariable Cox regression (HR: 0.92; 95% CI: 0.78-1.09; p = 0.34). CONCLUSIONS: Adjuvant chemotherapy has been increasingly utilized to treat salivary gland malignancies in recent years. Our findings highlight the importance of obtaining high-quality prospective data regarding the benefit of chemotherapy.

PURPOSE: Locoregionally recurrent head and neck cancer is a complex clinical scenario that often requires multimodality treatment. These patients have often previously received definitive treatment with a combination of surgery, radiation therapy, and systemic therapy, which can make further management difficult. A second isolated locoregional failure is rare and clinicians are faced with a challenge to optimize disease control while minimizing treatment-related toxicity. METHODS AND MATERIALS: In this report, we present the diagnosis, management, and outcomes of a patient with an isolated locoregional recurrence who was previously treated with two courses of radiation. The patient was treated with a second course of reirradiation using interstitial brachytherapy as well as a discussion regarding patient selection and optimal management for recurrent head and neck cancer. RESULTS: Repeat reirradiation using interstitial HDR-brachytherapy with the use of an alloderm spacer was successfully delivered to the patient for an in-field right neck nodal recurrence. He received a total EQD2/BED dose of 127.70/153.24 Gy. At 1-year followup, the patient was without evidence of recurrent disease or new significant side effects. CONCLUSION: Recurrent head and neck cancer should be managed with a multidisciplinary approach given the complex clinical scenario. Reirradiation is a commonly used salvage measure for recurrent head and neck cancer that requires careful planning and patient selection due to prior treatment-related effects and dose constraints. We reported a case of a second course of reirradiation using interstitial HDR-brachytherapy for locoregionally recurrent head and neck cancer and showed no recurrence of disease or worsening long term side effects at 1 year.

OBJECTIVES/HYPOTHESIS: Non-squamous cell carcinoma (SCC) malignancies are rare, but well described laryngeal pathologies. However, the epidemiology and clinical behavior of these tumors is not well studied. STUDY DESIGN: Retrospective cohort study. METHODS: Patients diagnosed with non-squamous cell larynx cancer from 2004 to 2017 in the National Cancer Database were selected. Demographic, clinicopathologic factors, treatments, and survival were analyzed. Univariable and multivariable cox regression were performed. Survival was compared with a propensity score-matched (PSM) population of laryngeal SCC patients. RESULTS: A total of 136,235 cases of larynx cancer were identified. After excluding SCC variants, 2,172 (1.6%) patients met inclusion criteria. The most common histology was chondrosarcoma (374, 17.2%), followed by small cell (345, 15.9%), and spindle cell carcinoma (268, 12.3%). The most common treatment was surgery (683, 31.4%) followed by chemoradiation (409, 18.8%) and surgery and adjuvant radiation (288, 13.3%). Overall, 3- and 5-year survival was 67.9% and 59.4%, respectively. In multivariate analysis controlling for age, stage, comorbidity, histology, and treatment modality; chondrosarcoma had the best survival (hazard ratio [HR] 0.11, confidence interval [CI] 0.07-0.19, P < .001). In a PSM population, matched for age, stage, comorbidity, and treatments; non-SCC patients had significantly lower survival (51.5% vs. 59.9%, P < .001). CONCLUSION: A diverse range of non-squamous cell malignancies occur in the larynx. In general, these tumors have poor survival, with few exceptions such as chondrosarcoma. While the majority of these histologies undergo surgical-based treatments in other sites, only 53% of patients underwent surgical-based treatment in the larynx. These data could guide clinicians in determining the outcome of treatment in these patients. LEVEL OF EVIDENCE: 4 Laryngoscope, 132:1771-1777, 2022.

BACKGROUND: Computerized surgical planning (CSP) in osseous reconstruction of head and neck cancer defects has become a mainstay of treatment. However, the consequences of CSP-designed titanium plating systems on planning adjuvant radiation remains unclear. METHODS: Two patients underwent head and neck cancer resection and maxillomandibular free fibula flap reconstruction with CSP-designed plates and immediate placement of osseointegrated dental implants. Surgical treatment was followed by adjuvant intensity modulated radiation therapy (IMRT). RESULTS: Both patients developed osteoradionecrosis (ORN), and one patient had local recurrence. The locations of disease occurred at the areas of highest titanium plate burden, possibly attributed to IMRT dosing inaccuracy caused by the CSP-designed plating system. CONCLUSION: Despite proven benefits of CSP-designed plates in osseous free flap reconstruction, there may be an underreported risk to adjuvant IMRT treatment planning leading to ORN and/or local recurrence. Future study should investigate alternative plating methods and materials to mitigate this debilitating outcome.

OBJECTIVE: Sinonasal cancer often presents as locoregionally advanced disease. National guidelines recommend management of stage T4b tumors with systemic therapy and radiotherapy, but recent studies suggest that including surgical resection in the multimodal treatment of these tumors may improve local control and survival. We queried the National Cancer Database to examine patterns of care and outcomes in T4b sinonasal squamous cell carcinoma (SCC). STUDY DESIGN: Prospectively gathered data. SETTING: National Cancer Database. METHODS: Patients with T4b N0-3 M0 sinonasal squamous cell carcinoma diagnosed in 2004 to 2016 were stratified between those who received chemoradiotherapy and those who underwent surgical resection with neoadjuvant or adjuvant treatment. The overall survival of each cohort was assessed via Kaplan-Meier analysis and Cox proportional hazard models, with repeat analysis after reweighting of data via inverse probability of treatment weighting. RESULTS: Among 805 patients included in analysis, 2-year overall survival for patients undergoing surgical resection was 60.8% (95% CI, 56.1%-65.9%), while for patients undergoing chemoradiotherapy it was 46.7% (95% CI, 41.9%-52.0%). On Cox regression analysis, the inclusion of surgery in management was associated with improved survival in univariate analysis (hazard ratio [HR], 0.723 [95% CI, 0.606-0.862]; P < .001) and multivariate analysis (HR, 0.739 [95% CI, 0.618-0.885]; P = .001). Results with reweighted data were consistent in univariate analysis (HR, 0.765 [95% CI, 0.636-0.920]; P = .004]). CONCLUSION: Surgical treatment with neoadjuvant or adjuvant treatment for stage T4b sinonasal SCC was associated with promising survival outcomes, suggesting a role for incorporating surgery in treatment of select T4b SCC, particularly when removal of all macroscopic disease is feasible.

OBJECTIVE: Acinic cell carcinoma (AciCC) is a rare, usually low-grade salivary malignancy. Evidence on rates of lymph node metastases (LNMs) is limited in pediatric patients and varies significantly (4%-45%) in adults. We set out to determine and compare rates of LNMs in pediatric and adult AciCC and to analyze their impact on survival, using the National Cancer Database. STUDY DESIGN: Historical cohort study. SETTING: National Cancer Database. METHODS: All AciCCs of the major salivary glands with complete clinical and pathologic nodal staging were selected between 2010 and 2016. Patient demographics, tumor characteristics, treatment, and survival were analyzed. Univariable and multivariable regression were performed to determine factors associated with LNMs and survival. RESULTS: We identified 57 (4.6%) pediatric patients (<18 years) and 1192 (95.4%) adults with AciCC. Clinical LNMs were rare in pediatric patients (n < 10) and adults (n = 88, 7.4%). Occult LNMs were uncommon in pediatric patients (n < 5) and adults (n = 41, 4.6%). Three-year overall survival for pediatric patients was 97.8%. Adults with LNM had worse 3-year overall survival than those without (66.0% vs 96.3%, P < .001). In multivariable regression, high-grade disease (hazard ratio, 10.15 [95% CI, 5.60-18.80]; P < .001) and T3-T4 tumors (hazard ratio, 2.80 [95% CI, 1.56-4.97]; P < .001) were associated with LNM in adult patients. CONCLUSION: LNMs in AciCC of the major salivary glands are rare in children and adults. However, high-grade and T3-T4 tumors are associated with an increased risk of LNM. LNM is associated with worse survival.

OBJECTIVE: Assess the testing rates and prognostic significance of human papilloma virus (HPV) status in hypopharynx malignancies. STUDY DESIGN: Historical cohort study. SETTING: National Cancer Database. METHODS: Review of the National Cancer Database was conducted between 2010 and 2017 for squamous cell carcinomas (SCCs) of the hypopharynx. We investigated how often the tumors were tested for HPV and whether it was associated with survival outcomes. RESULTS: A total of 13,269 patients with hypopharynx malignancies were identified. Most cases were not tested for HPV status (n = 8702, 65.6%). Of those tested, 872 (19.1%) were positive for HPV and 3695 (80.9%) were negative. The proportion of nonoropharyngeal SCCs tested for HPV increased nearly every year during the study, with roughly one-third of cases (31.9%) being tested in 2017. In the facilities classified as high-testing centers of nonoropharyngeal SCCs of the head and neck, 18.7% of hypopharyngeal tumors were HPV positive. HPV-negative status was associated with worse survival on multivariable analysis. In propensity score-matched analysis controlling for all factors significant in multivariable regression, 2-year survival remained higher in the HPV-positive cohort (77.7% vs 63.1%, P < .001). CONCLUSIONS: HPV-positive tumors constitute a sizable minority of hypopharynx tumors and are associated with improved survival. Expansion of HPV testing to hypopharynx malignancies may be warranted.

OBJECTIVES: To describe patterns of primary surgical treatments in patients with T4b oral cavity squamous cell carcinoma (OCSCC). STUDY DESIGN: Historical cohort study. SETTING: National Cancer Database. METHODS: Review of the National Cancer Database between 2004 and 2017 for all T4b OCSCCs. Only patients with curative treatment methods were included in the survival analysis. Surgical and nonsurgical outcomes were compared by multivariable and propensity score matching analysis. RESULTS: A total of 1515 cases of T4b OCSCC were identified. A minority of patients (n = 363, 24.0%) underwent curative treatment; among these, 206 (56.7%) underwent primary surgery. Median length of follow-up was 24 months. The 90-day mortality of patients who underwent surgical treatment was 1.0%. The 2-year survival was higher for patients who underwent surgery + chemoradiotherapy (CRT) as compared with CRT (64.6% vs 45.2%, P < .001). On multivariable analysis, surgery + CRT was associated with longer survival. In a propensity score-matched cohort of 312 patients, 2-year survival remained higher in the surgical group versus the nonsurgical group (59.4% vs 45.5%, P = .02). Among patients who underwent surgery + CRT, there was no difference in 2-year survival between clinical T4a and T4b (59% vs 64.6%, P = .20). CONCLUSIONS: A minority of patients with T4b OCSCC undergo treatments with curative intent. A subset of patients underwent primary surgical treatment, which was associated with longer survival. The T4b classification might entail a heterogenous group, and further studies in revision of this classification might be justified.

OBJECTIVES: The role of locoregional radiotherapy for metastatic oropharyngeal squamous cell cancer (OPSCC) is unclear. We investigated the impact of head and neck radiotherapy on survival in de novo metastatic OPSCC patients who received systemic therapy. METHODS: We queried the NCDB from 2004-2015 for metastatic OPSCC patients at diagnosis with known HPV-status who received systemic therapy. The association of head and neck radiotherapy with overall survival was analyzed using the Kaplan-Meier method, Cox proportional hazards model, and propensity score-matched analysis adjusting for demographic and disease-specific prognostic factors. RESULTS: Of the 2,139 patients with metastatic OPSCC who presented with metastases and received systemic treatment, we identified 556 patients with known HPV-status. Among these 556 patients, 49% were HPV-positive and 56% received head and neck radiotherapy. With a median follow-up of 17.5 months (IQR 6.0-163.4 months), radiotherapy was associated with significantly improved 1-year OS (67% vs 58%, log-rank P < .001) which remained significant on MVA (HR 0.78 95% CI 0.62-0.97 P = .029). In HPV-status subgroup analysis, a survival benefit was identified in HPV-positive patients (1-year OS 77% vs 67%, log-rank P < .001) but not in HPV-negative patients. Results were consistent on a propensity score-matched analysis of 212 HPV-positive matched patients (HR 0.66, 95% CI 0.49-0.83, P < .001). CONCLUSION: The survival of metastatic OPSCC remains limited. In this large series of patients with known HPV-status, head and neck radiotherapy was associated with longer survival in those with HPV-associated disease. These data could guide management of this challenging group of patients for head and neck cancer practitioners. LEVEL OF EVIDENCE: 3 Laryngoscope, 131:E1847-E1853, 2021.

OBJECTIVE: To investigate differences in epidemiology of oropharyngeal squamous cell carcinoma (OPSCC) with regards to human papillomavirus (HPV), race, and socioeconomic status (SES) using the National Cancer Database (NCDB). STUDY DESIGN: Population-based cohort study. SETTING: Racial and socioeconomic disparities in survival of OPSCC have been previously acknowledged. However, the distribution of HPV-related cancers and its influence on survival in conjunction with race and SES remain unclear. SUBJECTS AND METHODS: All patients with OPSCC in the NCDB with known HPV status from 2010 to 2016 were included. Differences in presentation, HPV status, treatment, and outcomes were compared along racial and socioeconomic lines. Univariable and multivariable Cox regression survival analyses were performed. RESULTS: In total, 45,940 patients met criteria. Most were male (38,038, 82.8%), older than 60 years (23,456, 51.5%), and white (40,156, 87.4%), and lived in higher median income areas (>$48,000, 28,587, 62.2%). Two-thirds were HPV positive (31,007, 67.5%). HPV-negative disease was significantly more common in lower SES (<$38,000, 2937, 41.5%, P < .001) and among blacks (1784, 55.3%, P < .001). Median follow-up was 33 months. Five-year overall survival was 81.3% (95% CI, 80.5%-82.1%) and 59.6% (95% CI, 58.2%-61.0%) in HPV-positive and HPV-negative groups, respectively. In univariable and multivariable analyses controlling for HPV status, age, stage, and treatment, black race (hazard ratio [HR], 1.22; 95% CI, 1.11-1.34; P < .001) and low SES (HR, 1.58; 95% CI, 1.45-1.72; P < .001) were associated with worse survival. CONCLUSION: Significant differences in HPV status exist between socioeconomic and racial groups, with HPV-negative disease more common among blacks and lower SES. When controlling for HPV status, race and SES still influence outcomes in oropharyngeal cancers.

OBJECTIVE: To investigate the patterns of care and outcomes of treatment of early stage tonsil cancers, controlling for human papillomavirus (HPV) status. STUDY DESIGN: Historical cohort study. SETTING: National Cancer Database (NCDB). METHODS: Review of the NCDB between 2010 and 2017 for all T1-2N0M0 tonsillar squamous cell carcinoma (SCC). Demographics, clinical characteristics, HPV status, treatment regimens, and survival were analyzed. RESULTS: A total of 4720 patients were identified with early stage SCC of the tonsil. Most were tested for HPV (2759 [58.5%]). Among tested patients, 1758 (63.7%) were positive for HPV and 1001 (36.3%) were negative for HPV. HPV-positive patients had higher 3-year survival compared to HPV-negative patients (93.2% vs 77.8%, P < .001). Among HPV-positive patients, there was no significant difference in survival between treatment cohorts. However, in the HPV-negative cohort, 3-year survival was higher in both bimodality surgical-based settings (tonsillectomy + neck dissection + radiotherapy, 86.0% vs chemoradiotherapy, 69.6%, P = .01) and for all surgical-based treatments when compared to nonsurgical management (84.6% vs 69.3%, P < .001). This difference was maintained in multivariable regression controlling for age, sex, comorbidities, clinical T stage, and treatments. In a subpopulation of HPV-negative patients propensity score matched by all factors significant in multivariable analysis, 3-year survival remained higher in the surgically treated group compared to the nonsurgically treated cohort (84.9% vs 67.1%, P < .001). CONCLUSIONS: Surgical- or radiation-based treatment resulted in similar survival in early stage HPV-positive tonsil cancer. Surgical-based treatments were associated with longer survival in HPV-negative cancers. These findings should be further investigated in a randomized prospective trial.
