Abstract
OBJECTIVE/HYPOTHESIS To investigate the endovascular intervention or extracranial/intracranial (EC/IC) vascular bypass in the management of patients with head and neck cancer-related carotid blowout syndrome (CBS). STUDY DESIGN Retrospective case series. METHODS Retrospective analysis of clinical data of patients with head and neck cancer-related CBS treated by endovascular intervention and/or EC/IC vascular bypass, analysis of its bleeding control, neurological complications, and survival results. RESULTS Thrity-seven patients were included. Twenty-five were associated with external carotid artery (ECA); twelve were associated with internal or common carotid artery (ICA/CCA). All patients with ECA hemorrhage were treated with endovascular embolization. Of the 12 patients with ICA/CCA hemorrhage, 9 underwent EC/IC bypass, 1 underwent endovascular embolization, and 3 underwent endovascular stenting. For patients with ECA-related CBS, the median survival was 6 months, and the 90-day, 1-year, and 2-year survival rates were 67.1%, 44.7%, and 33.6%, respectively; the estimated rebleeding risk at 1-month, 6-month, and 2-year was 7.1%, 20.0%, and 31.6%, respectively. For patients with ICA/CCA-related CBS, the median survival was 22.5 months, and the 90-day, 1-year, and 2-year survival rates were 92.3%, 71.8%, and 41.0%, respectively; the estimated rebleeding risk at 1 month, 6 months, and 2 years is 7.7%,15.4%, and 15.4%, respectively. ICA/CCA-related CBS patients have significantly longer survival time and lower risk of rebleeding, which may be related to the more use of EC/IC vascular bypass as a definite treatment. CONCLUSIONS For patients with ICA/CCA-related CBS, if there is more stable hemodynamics, longer expected survival, EC/IC vascular bypass is preferred.

Abstract
INTRODUCTION Neuroendocrine tumors of the head and neck are rare and arise either from epithelial or neuronal origin. Debate continues over the classification systems and appropriate management of these pathologies. OBJECTIVE By investigating a small set of cases of high grade epithelial-derived neuroendocrine tumors of the head and neck (neuroendocrine carcinomas or NEC) from one institution, we compare survival rates of NEC of the head and neck to pulmonary NEC. METHODS We identified patients from pathology records with neuroendocrine carcinomas of the head and neck and retrospectively collected clinical data as well as immunohistochemical (IHC) staining data. RESULTS We identified 14 patients with NEC, arising from the parotid (n = 5), nasal cavity (n = 4), larynx (n = 2), and other regions (n = 2). One additional patient had NEC arising in two sites simultaneously (parotid and nasal). Staining patterns using IHC were relatively consistent across specimens, showing reactivity to chromogranin and synaptophysin in 73% and 100% of specimens, respectively. Treatment courses varied across patients and included combinations of surgery, chemotherapy, and/or radiation. The overall survival rate at 1, 2, and 5 years of these patients was 56%, 56%, and 43% with a mean follow-up time of 2.12 years. CONCLUSION Compared to NEC arising in the lung, this subset of patients had better survival rates, but worse survival rates than the more common squamous cell carcinoma of the head and neck.

Abstract
Perineural invasion (PNI) is frequently associated with aggressive clinical behaviour in head and neck cutaneous squamous cell carcinoma (HNcSCC) leading to local recurrence and treatment failure. This study evaluates the gene expression profiles of HNcSCC with PNI using a differential expression analysis approach and constructs a tailored gene panel for sensitivity and specificity analysis. 45 cases of HNcSCC were stratified into three groups (Extensive, Focal and Non PNI) based on predefined clinicopathological criteria. Here we show HNcSCC with extensive PNI demonstrates significant up- and down-regulation of 144 genes associated with extracellular matrix interactions, epithelial to mesenchymal transition, cell adhesion, cellular motility, angiogenesis, and cellular differentiation. Gene expression of focal and non PNI cohorts were indistinguishable and were combined for further analyses. There is clinicopathological correlation between gene expression analysis findings and disease behaviour and a tailored panel of 10 genes was able to identify extensive PNI with 96% sensitivity and 95% specificity.

Abstract
Desmosomes are intercellular adhesion complexes involved in various aspects of epithelial pathophysiology, including tissue homeostasis, morphogenesis, and disease development. Recent studies have reported that the abnormal expression of various desmosomal components correlates with tumor progression and poor survival. In addition, desmosomes have been shown to act as a signaling platform to regulate the proliferation, invasion, migration, morphogenesis, and apoptosis of cancer cells. The occurrence and progression of head and neck cancer (HNC) is accompanied by abnormal expression of desmosomal components and loss of desmosome structure. However, the role of desmosomal components in the progression of HNC remains controversial. This review aims to provide an overview of recent developments showing the paradoxical roles of desmosomal components in tumor suppression and promotion. It offers valuable insights for HNC diagnosis and therapeutics development.

Abstract
Cutaneous head and neck melanoma is a separate subgroup of cutaneous melanoma that has a worse prognosis than other primary sites. The aim of this article is to examine the significance of sex and site of primary lesion as additional risk factors. Primary localization distribution and metastatic disease in the neck in a retrospective cohort of 159 patients with cutaneous head and neck malignant melanoma were analyzed. Men develop primary melanoma more frequently than women in the left peripheral head and neck regions (P = .0364), as well as clinically visible and occult metastatic disease in the left side of the neck (P = .0138). Patients with clinically occult regional metastatic disease showed a significantly poorer survival rate than the rest of the group that underwent elective neck dissections (P = .0270). Left-sided disease in male patients may be an additional risk factor in cutaneous head and neck melanoma. Performing elective neck dissections in high-risk patients might identify patients with occult metastatic disease and worse prognosis but does not offer any significant therapeutic benefit.

Abstract
The association of immune markers and clinicopathologic features and patient outcome has not been extensively studied in Merkel cell carcinoma (MCC). We correlated tumoral PD-L1 and IDO1 expression, and intratumoral CD8+ and FoxP3+ lymphocytes count with clinicopathologic variables, Merkel cell polyomavirus (MCPyV) status, and patient outcomes in a series of 132 MCC. By univariate analyses, tumoral PD-L1 expression >1% and combined tumoral PD-L1 >1% and high intratumoral FoxP3+ lymphocyte count correlated with improved overall survival (OS) (p = 0.016, 0.0072), MCC-specific survival (MSS) (p = 0.019, 0.017), and progression-free survival (PFS) (p = 0.043, 0.004, respectively). High intratumoral CD8+ and FoxP3+ lymphocyte count correlated with longer MSS (p = 0.036) and improved PFS (p = 0.047), respectively. Ulceration correlated with worse OS and worse MSS. Age, male gender, and higher stage (3 and 4) significantly correlated with worse survival. MCPyV positivity correlated with immune response. By multivariate analyses, only ulceration and age remained as independent predictors of worse OS; gender and stage remained for shorter PFS. Tumoral PD-L1 expression and increased density of intratumoral CD8+ lymphocytes and FoxP+ lymphocytes may represent favorable prognosticators in a subset of MCCs. Tumoral PD-L1 expression correlated with intratumoral CD8+ and FoxP3+ lymphocytes, which is supportive of an adaptive immune response.

Abstract
Fibroblast growth factor receptor 1 (FGFR1) has recently been identified as a promising novel therapeutic target and prognostic marker in different types of cancer. In the present study, a meta-analysis was performed to clarify the correlation between FGFR1 and the survival outcomes of head and neck squamous cell carcinoma (HNSCC) patients. PubMed, Embase, and Web of Science were systematically searched for relevant studies in order to explore the prognostic significance of FGFR1 in HNSCC. Hazards ratios (HR) and 95% confidence intervals (CI) were collected to estimate the correlation between overexpression and amplification of FGFR1 and survival outcomes of HNSCC patients. Nine studies including 2708 patients with HNSCC were finally selected for the meta-analysis. The results indicated that FGFR1 predicted poor overall survival (OS) (HR, 1.97; 95% CI, 1.49–2.61, P<0.001) in HNSCC patients. Futhermore, FGFR1 was related to poor OS in human papillomavirus (HPV) negative HNSCC not in HPV positive HNSCC patients. Subgroup analysis stratified by molecular abnormalities, such as overexpression or amplification showed the similar results. The present study demonstrated that HNSCC patients with FGFR1 overexpression and amplification were more likely to exhibit poorer survival.

Abstract
Importance Nivolumab and pembrolizumab are approved for treating platinum-refractory recurrent or metastatic head and neck squamous cell carcinoma (R/M HNSCC). Physicians and patients are uncertain which drug is preferable, rendering a cost-effectiveness comparison between them necessary. Objective To evaluate the cost-effectiveness of nivolumab vs pembrolizumab in treating platinum-refractory R/M HNSCC. Design, Setting, and Participants Both the network meta-analysis and cost-effectiveness analysis included patients from the CheckMate 141 and the KEYNOTE 040 phase 3 randomized clinical trials. The Checkmate 141 trial started on May 1, 2014, with the present analysis based on a September 2017 data cutoff. The KEYNOTE 040 trial started on November 17, 2014, with the present analysis based on a May 15, 2017, data cutoff. A bayesian network meta-analysis that included 856 patients was carried out, and a cost-effectiveness analysis that included 487 patients was conducted by developing a partitioned survival model, both between February and November 2020. The robustness of the model was assessed via 1-way, 2-way, and probabilistic sensitivity analyses; subgroup analyses were included; and scenario analyses were conducted to investigate the associations of dosage adjustment of nivolumab with cost-effectiveness. Main Outcomes and Measures Life-years, quality-adjusted life-years (QALYs), overall costs, and incremental cost-effectiveness ratios (ICERs) were measured. Results In the cost-effectiveness analysis that included 487 patients, for US health care payers, when nivolumab was administered based on patient weight (3 mg/kg biweekly), at a willingness-to-pay (WTP) threshold of $100 000 per QALY, the probability of nivolumab being cost-effective compared with pembrolizumab was 56%; at a WTP threshold of $150 000 per QALY, the probability was 62%. When nivolumab was administered at a fixed dose of 240 mg biweekly or 480 mg monthly, at a WTP threshold of $100 000 per QALY, the probability of nivolumab being cost-effective was 42% to 45%; at a WTP threshold of $150 000 per QALY, the probability was 52% to 55%. Conclusions and Relevance Findings from this network meta-analysis and cost-effectiveness analysis suggest considering both WTP threshold and patient body weight when choosing between nivolumab and pembrolizumab for the treatment of patients with platinum-refractory R/M HNSCC. When the WTP threshold was $100 000 per QALY, for patients weighing less than 72 kg, nivolumab (3 mg/kg, biweekly) was considered cost-effective; otherwise, pembrolizumab was preferable. When the WTP threshold was $150 000 per QALY, nivolumab (3 mg/kg biweekly) was considered cost-effective for patients weighing less than 75 kg; otherwise, fixed-dose nivolumab (240 mg biweekly or 480 mg monthly) provided more cost savings.

Abstract
OBJECTIVES/HYPOTHESIS Head and neck cancer (HNC) is the fifth most common malignancy in sub-Saharan Africa, a region with hyperendemic human immunodeficiency virus (HIV)-infection. HIV patients have higher rates of HNC, yet the effect of HIV-infection on oncologic outcomes and treatment toxicity is poorly characterized. STUDY DESIGN Prospective observational cohort study. METHODS HNC patients attending a government-funded oncology clinic in Botswana were prospectively enrolled in an observational cohort registry from 2015 to 2019. Clinical characteristics were analyzed via Cox proportional hazards and logistic regression followed by secondary analysis by HIV-status. Overall survival (OS) was evaluated via Kaplan-Meier. RESULTS The study enrolled 149 patients with a median follow-up of 23 months. Patients presented with advanced disease (60% with T4-primaries), received limited treatment (19% chemotherapy, 8% surgery, 29% definitive radiation [RT]), and had delayed care (median time from diagnosis to RT of 2.5 months). Median OS was 36.2 months. Anemia was associated with worse survival (HR 2.74, P = .001). Grade ≥ 3 toxicity rate with RT was 30% and associated with mucosal subsite (OR 4.04, P = .03) and BMI < 20 kg/m2 (OR 6.04, P = .012). Forty percent of patients (n = 59) were HIV-infected; most (85%) were on antiretroviral therapy, had suppressed viral loads (90% with ≤400 copies/mL), and had immunocompetent CD4 counts (median 400 cells/mm3 ). HIV-status was not associated with decreased receipt or delays of definitive RT, worse survival, or increased toxicity. CONCLUSIONS Despite access to government-funded care, HNC patients in Botswana present late and have delays in care, which likely contributes to suboptimal survival outcomes. While a disproportionate number has comorbid HIV infection, HIV-status does not adversely affect outcomes. LEVEL OF EVIDENCE 2c Laryngoscope, 131:E1558-E1566, 2021.

Abstract
PURPOSE The rapid spread of the SARS-CoV-2 pandemic around the world caused most healthcare services to turn substantial attention to treatment of these patients and also to alter the structure of healthcare systems to address an infectious disease. As a result, many cancer patients had their treatment deferred during the pandemic, increasing the time-to-treatment initiation, the number of untreated patients (which will alter the dynamics of healthcare delivery in the post-pandemic era) and increasing their risk of death. Hence, we analyzed the impact on global cancer mortality considering the decline in oncology care during the COVID-19 outbreak using head and neck cancer, a known time-dependent disease, as a model. METHODS An online practical tool capable of predicting the risk of cancer patients dying due to the COVID-19 outbreak and also useful for mitigation strategies after the peak of the pandemic has been developed, based on a mathematical model. The scenarios were estimated by information of 15 oncological services worldwide, given a perspective from the five continents and also some simulations were conducted at world demographic data. RESULTS The model demonstrates that the more that cancer care was maintained during the outbreak and also the more it is increased during the mitigation period, the shorter will be the recovery, lessening the additional risk of dying due to time-to-treatment initiation. CONCLUSIONS This impact of COVID-19 pandemic on cancer patients is inevitable, but it is possible to minimize it with an effort measured by the proposed model.

Abstract
OBJECTIVE No surgical or radiotherapeutic treatment guidelines exist for oligometastatic head and neck squamous cell carcinoma (oHNSCC), and only recently have interventions with curative intent been studied. Herein, we sought to elucidate survival rates among patients with oHNSCC to determine if treatment with curative intent is warranted in this population. STUDY DESIGN Retrospective chart review. METHODS We retrospectively reviewed cases of oHNSCC treated between March 1998 and March 2018. Fisher's exact test was used to compare patients treated with radiotherapy (RT) to those who underwent surgical excision and to compare outcomes of patients with oligometastases at the time of initial presentation to those that developed oligometastatic disease after primary treatment. RESULTS Eighty one patients with metastases to the lungs, ribs, pelvis, vertebral column, liver, clavicle, and sternum were included. Overall, 32 patients (40%) were alive 5 years post-treatment. The site of metastasis, the modality of treatment, and the time of development of oligometastatic disease did not significantly affect 5-year survival. CONCLUSION Herein, we demonstrate that multi-modality treatment of oHNSCC is warranted for some patients with an estimated 40% 5-year survival. Aggressive treatment of the primary and regional sites is necessary in addition to treatment of the metastatic site and incurs a survival benefit compared to patients with metastatic HNSCC treated with systemic therapy alone. oHNSCC should be approached separately from polymetastatic disease. Patients should be counseled about the possibility for long-term survival, and aggressive initial treatment with the intention for cure should be considered in this population.

Abstract
BACKGROUND The clinical significance of tumor-stroma ratio (TSR) has been examined in many tumors. Here we systematically reviewed all studies that evaluated TSR in head and neck cancer. METHODS Four databases (Scopus, Medline, PubMed and Web of Science) were searched using the term tumo(u)r-stroma ratio. The preferred reporting items for systematic reviews and meta-analyses (PRISMA) were followed. RESULTS TSR was studied in nine studies of different subsites (including cohorts of nasopharyngeal, oral, laryngeal and pharyngeal carcinomas). In all studies, TSR was evaluated using hematoxylin and eosin staining. Classifying tumors based on TSR seems to allow for identification of high-risk cases. In oral cancer, specifically, our meta-analysis showed that TSR is significantly associated with both cancer-related mortality (HR 2.10, 95%CI 1.56-2.84) and disease-free survival (HR 1.84, 95%CI 1.38-2.46). CONCLUSIONS The assessment of TSR has a promising prognostic value and can be implemented with minimum efforts in routine head and neck pathology.

Abstract
Squamous cell carcinomas of the lung, head and neck, esophagus, and cervix account for more than two million cases of cancer per year worldwide with very few targetable therapies available and minimal clinical improvement in the past three decades. Although these carcinomas are differentiated anatomically, their genetic landscape shares numerous common genetic alterations. Amplification of the third chromosome's distal portion (3q) is a distinguishing genetic alteration in most of these carcinomas and leads to copy-number gain and amplification of numerous oncogenic proteins. This area of the chromosome harbors known oncogenes involved in squamous cell fate decisions and differentiation, including TP63, SOX2, ECT2, and PIK3CA. Furthermore, novel targetable oncogenic kinases within this amplicon include PRKCI, PAK2, MAP3K13, and TNIK. TCGA analysis of these genes identified amplification in more than 20% of clinical squamous cell carcinoma samples, correlating with a significant decrease in overall patient survival. Alteration of these genes frequently co-occurs and is dependent on 3q-chromosome amplification. The dependency of cancer cells on these amplified kinases provides a route toward personalized medicine in squamous cell carcinoma patients through development of small-molecules targeting these kinases.

[PMID: 33802627 PMCID: PMC7998447 DOI: 10.3390/cells10030539] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2020] [Revised: 02/19/2021] [Accepted: 02/27/2021] [Indexed: 02/07/2023] Open
Abstract
Epithelial to mesenchymal transition (EMT) is clinically relevant in head and neck squamous cell carcinoma (HNSCC). We hypothesized that EMT-transcription factors (EMT-TFs) and an anti-EMT factor, Krüppel-like-factor-4 (KLF4) regulate EMT in HNSCC. Ten control mucosa and 37 HNSCC tissue samples and three HNSCC cell lines were included for investigation of EMT-TFs, KLF4 and vimentin at mRNA and protein levels. Slug gene expression was significantly higher, whereas, KLF4 gene expression was significantly lower in HNSCC than in normal mucosa. In the majority of HNSCC samples, there was a significant negative correlation between KLF4 and Slug gene expression. Slug gene expression was significantly higher in human papilloma virus (HPV) negative HNSCC, and in tumor samples with irregular p53 gene sequence. Transforming-growth-factor-beta-1 (TGF- β1) contributed to downregulation of KLF4 and upregulation of Slug. Two possible regulatory pathways could be suggested: (1) EMT-factors induced pathway, where TGF-β1 induced Slug together with vimentin, and KLF4 was down regulated at the same time; (2) p53 mutations contributed to upregulation and stabilization of Slug, where also KLF4 could co-exist with EMT-TFs.

Abstract
BACKGROUND It is unclear if a non-radical diagnostic biopsy entails a higher risk for metastasis and poorer survival for patients with cutaneous head and neck melanoma (cHNM). AIMS/OBJECTIVES To assess whether or not initial diagnostic biopsy modality and radicality (clear, positive, or narrow histopathological margins) influence recurrence and survival in patients with cHNM. MATERIALS AND METHODS Histopathological radicality of initial diagnostic biopsies and outcome for 368 consecutive cHNM patients, clinically asymptomatic of metastatic disease and referred to a tertiary care academic center for sentinel lymph node staging from 2004 through 2018, were retrospectively analyzed. RESULTS Patients with positive (n = 133) or narrow (0.1-0.5 mm) (n = 34) histopathological margins had significantly worse loco-regional (p=.004) and distant control (p=.004) as well as lower overall (p=.017) and melanoma specific (p=.0002) survival than 201 patients with clear margins. Multivariate analysis indicated positive or narrow histopathological margins as independent negative prognostic factors for melanoma specific survival (HR 2.16, p=.015), together with deeper Breslow (HR 1.17, p=.00001) and ulceration (HR 2.49, p=.003). CONCLUSIONS AND SIGNIFICANCE Non-radical primary diagnostic biopsies increase the risk for metastatic disease and impair survival in cHNM. Accordingly, radical melanoma diagnostic procedures should be encouraged in the head and neck region when possible.

Abstract
The overwhelming majority of head and neck cancers and related deaths occur in low- and middle-income countries, which have challenges related to burden of disease versus access to care. Yet the additional health care burden of the COVID-19 pandemic has also impacted access to care for patients with head and neck cancer in the United States. This article focuses on challenges and innovation in prioritizing head and neck cancer care in Sub-Saharan Africa, the Indian experience of value-added head and neck cancer care in busy and densely populated regions, and strategies to optimize the management of head and neck cancer in the United States during the COVID-19 pandemic.

Abstract
BACKGROUND Computed tomography (CT)-defined sarcopenia is a demonstrated poor prognostic factor in patients with cancer; however, its influence on outcomes for patients with head and neck cancer (HNC) has not been established. OBJECTIVE This review synthesizes current knowledge regarding the association between CT-defined sarcopenia and outcomes for adult patients undergoing radiotherapy with or without other treatment modalities of curative intent for HNC. METHODS A systematic review of the literature published between January 2004 and June 2019 was conducted in Medline, Embase, Cumulative Index of Nursing and Allied Health Literature, Allied and Complementary Medicine Database, and PubMed. Empirical studies of CT-defined sarcopenia in adult patients (≥18 years) with HNC who had completed radiotherapy of curative intent with or without other treatment modalities were included. Outcomes reported included survival, prolonged radiotherapy breaks, and chemotherapy toxicity. Study quality was assessed using the American Academy of Nutrition and Dietetics Quality Criteria Checklist. Synthesis of outcomes and clinical relevance was performed using the Grading of Recommendations Assessment, Development, and Evaluation system. RESULTS Of 11 studies (n = 3,461) identified, 3 were positive and 8 were neutral quality. Studies were heterogeneous in HNC diagnosis, ethnicity, definition of sarcopenia, CT level of evaluation, and skeletal muscle index threshold value. Eight definitions for sarcopenia were identified with pretreatment prevalence of 6.6% to 70.9% and posttreatment prevalence of 12.4% to 65.8%. Pretreatment sarcopenia was independently associated with reduced: overall survival (OS), 3-year OS, disease-free survival, prolonged radiotherapy breaks, and chemotherapy-related toxicities. Posttreatment sarcopenia was independently associated with reduced OS and 5-year OS. The overall certainty of evidence according to Grading of Recommendations Assessment, Development and Evaluation criteria was low for OS; 3-year, 5-year, and 10-year OS; locoregional control; locoregional failure; progression-free survival; metastasis-free survival, disease-specific survival; and disease-free survival and very low for distant metastasis, prolonged radiotherapy breaks, and chemotherapy toxicity-related outcomes. CONCLUSIONS CT-defined sarcopenia is independently associated with reduced OS and treatment completion in patients with HNC and holds a clinically meaningful prognostic value. The certainty of the evidence requires strengthening with further research. Understanding the impact sarcopenia has on outcomes for these patients has implications for informing potential nutrition interventions and facilitating individualized care.

Socioeconomic disparities in head and neck cancer survival in Germany: a causal mediation analysis using population-based cancer registry data. J Cancer Res Clin Oncol 2021; 147:1325-1334.

Abstract
PURPOSE Despite recent improvements in cancer treatment in Germany, a marked difference in cancer survival based on socioeconomic factors persists. We aim to quantify the effect of socioeconomic inequality on head and neck cancer (HNC) survival. METHODS Information on 20,821 HNC patients diagnosed in 2009-2013 was routinely collected by German population-based cancer registries. Socioeconomic inequality was defined by the German Index of Socioeconomic Deprivation. The Cox proportional regression and relative survival analysis measured the survival disparity according to level of socioeconomic deprivation with respective confidence intervals (CI). A causal mediation analysis was conducted to quantify the effect of socioeconomic deprivation mediated through medical care, stage at diagnosis, and treatment on HNC survival. RESULTS The most socioeconomically deprived patients were found to have the highest hazard of dying when compared to the most affluent (Hazard Ratio: 1.25, 95% CI 1.17-1.34). The most deprived patients also had the worst 5-year age-adjusted relative survival (50.8%, 95% CI 48.5-53.0). Our mediation analysis showed that most of the effect of deprivation on survival was mediated through differential stage at diagnosis during the first 6 months after HNC diagnosis. As follow-up time increased, medical care, stage at diagnosis, and treatment played no role in mediating the effect of deprivation on survival. CONCLUSION This study confirms the survival disparity between affluent and deprived HNC patients in Germany. Considering data limitations, our results suggest that, within six months after HNC diagnosis, the elimination of differences in stage at diagnosis could reduce survival inequalities.

PLoS One 2021; 16:e0246252. [PMID: 33534860 PMCID: PMC7857613 DOI: 10.1371/journal.pone.0246252] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/10/2020] [Accepted: 01/18/2021] [Indexed: 12/21/2022] Open
Abstract
OBJECTIVE To date, no study has evaluated the detection rate of head and neck squamous cell carcinoma (HNSCC) in cause-of-death records in Europe. Our objectives were to compare the number of deaths attributable to HNSCC from two national databases in France and to identify factors associated with under-reporting of HNSCC in cause-of-death records. METHODS The national hospital discharge database and the national underlying cause-of-death records were compared for all HNSCC-attributable deaths in adult patients from 2008 to 2012 in France. Factors associated with under-reporting of HNSCC in cause-of-death records were assessed using multivariate Poisson regression. RESULTS A total of 41,503 in-hospital deaths were attributable to HNSCC as compared to 25,647 deaths reported in national UCoD records (a detection rate of 62%). Demographics at death were similar in both databases with respect to gender (83% men), age (54% premature deaths at 25-64 years), and geographic distribution. In multivariate Poisson regression, under-reporting of HNSCC in cause-of-death records significantly increased in 2012 compared to 2010 (+7%) and was independently associated with a primary HNSCC site other than the larynx, a former primary or second synchronous cancer other than HNSCC, distant metastasis, palliative care, and death in hospitals other than comprehensive cancer care centers. The main study results were robust in a sensitivity analysis which also took into account deaths outside hospital (overall, 51,129 HNSCC-attributable deaths; a detection rate of 50%). For the year 2012, the age-standardized mortality rate for HNSCC derived from underlying cause-of-death records was less than half that derived from hospital discharge summaries (14.7 compared to 34.1 per 100,000 for men and 2.7 compared to 6.2 per 100,000 for women). CONCLUSION HNSCC is largely under-reported in cause-of-death records. This study documents the value of national hospital discharge databases as a complement to death certificates for ascertaining cancer deaths.

Abstract
BACKGROUND/AIM Prognosis plays a vital role in head and neck squamous cell carcinoma (HNSCC) patient management and decision-making. This study aimed to identify the role of BP180 as a prognostic factor in HNSCC. PATIENTS AND METHODS Protein expression of bullous pemphigoid antigen II (BP180) was verified by immunohistochemistry (IHC) in a tissue microarray study of 202 cases. RESULTS IHC analysis revealed that protein expression of BP180 among HNSCC patients differed significantly in the presence and absence of neural invasion, and according to T status in laryngeal and pharyngeal cancer subgroups. Overall survival and multivariate analysis showed that positive BP180-IHC and advanced clinical stage were significant independent positive predictors of mortality in HNSCC patients. In addition, in the oral cancer subgroup, independent positive predictors were positive BP180-IHC, advanced N status and neural invasion. In laryngeal and pharyngeal cancer subgroups, predictors were positive BP180-IHC and advanced clinical stage. CONCLUSION BP180 is a prognostic factor in head and neck squamous cell carcinoma.

Abstract
Head and neck squamous cell carcinoma (HNSCC) is the sixth common malignancy worldwide. The tumor microenvironment is highly related to tumor initiation, progression, and prognosis. This study aims to screen the tumor microenvironment related key genes of prognostic value for HNSCC.The gene expression and clinical data for HNSCC were downloaded from the cancer genome atlas (TCGA). The immune/stromal/ESTIMATE scores were downloaded from the website of the MD Anderson Cancer Center. Correlation of patient gender and tumor grade with immune/stromal/ESTIMATE score was tested. Patients were divided into low and high immune/stromal/ESTIMATE score subgroups. Survival analysis was performed to evaluate the prognostic value of the immune/stromal/ESTIMATE score. Tumor microenvironment related differentially expressed genes were determined and applied for functional enrichment analysis and protein-protein interaction network was predicted. The prediction value of the common differentially expressed genes on patient survival was tested.Four hundred eighty samples with complete clinical, expression data, and immune/stromal/ESTIMATE scores were enrolled for analysis. Immune/stromal/ESTIMATE score was higher in female patients than males. A total of 44 common differentially expressed genes were screened in high and low immune/stromal/ESTIMATE score subgroups. Of the 44 genes, 7 genes (ADGRG7, CSN3, CST8, KRT81, MUC7, MYH6, and SEZ6) were found to be closely related to patient survival. Enrichment analysis showed that the differentially expressed genes mainly enriched in the protein-coupled receptor signaling pathway, extracellular region, G-protein coupled receptor activity, salivary secretion, and regulation of lipolysis in adipocytes. Protein-protein interaction analysis revealed that POSTN and OGN were crucial microenvironments related genes.Tumor microenvironment related genes ADGRG7, CSN3, CST8, KRT81, MUC7, MYH6, and SEZ6 are valuable predictors for HNSCC patient survival. POSTN and OGN are crucial in modulating the microenvironment and tumor biology for HNSCC.

Abstract
BACKGROUND In recent years, a number of clinical trials for antibody drugs targeting programmed cell death protein 1 (PD1)/programmed cell death 1 ligand 1 (PD-L1) have been carried out on recurrent or metastatic head and neck squamous cell carcinoma (R/M SCCHN) and reported promising prospects. To further evaluate and understand the effects and risk of anti-PD1/PD-L1 monotherapy vs standard of care (SoC) in R/M SCCHN, we conducted this meta-analysis of published randomized controlled trials. METHOD The potential eligible trials were searched from Cochrane library and Pubmed and Embase databases. Randomized controlled trials evaluating the effects and risk of anti-PD1/PD-L1 monotherapy vs SoC in platinum refractory R/M SCCHN were selected. The outcomes, including objective response rate, disease control rate, progression-free survival, overall survival, and treatment-related adverse events, were extracted and pooled. RESULTS 1345 patients with R/M SCCHN from three randomized controlled trials were enrolled in this analysis. Compared with SoC, anti-PD1/PD-L1 monotherapy could provide statistically significant overall survival benefit, hazard ratio (95% confidence interval ) = 0.79 [0.70-0.90]. However, we observed no significant difference between 2 treatments in progression-free survival (hazard ratio [95% confidence interval] = 0.96 [0.85-1.09]). Furthermore, anti-PD1/PD-L1 monotherapy caused less treatment-related adverse events than standard of care. CONCLUSION Anti-PD1/PD-L1 monotherapy could indeed reduce the risk of death in R/M SCCHN patients, and provide higher safety vs SoC. Expression level of PD-L1 may be a useful biomarker for selecting patients with better response to anti-PD1/PD-L1 monotherapy.

Abstract
Background: Head and neck squamous cell carcinoma (HNSCC) is a common malignancy with high mortality and morbidity worldwide, but the underlying biological mechanisms of molecules and tumor infiltrating-immune cells (TIICs) are still unknown. Methods and Results: We obtained mRNAs, lncRNAs, and miRNAs expression profiles of 546 HNSCC from The Cancer Genome Atlas (TCGA) database to develop a ceRNA network. CIBERSORT was employed to estimate the fraction of 22 types of TIICs in HNSCC. Univariate and multivariate Cox regression and lasso regression analyses were used to develop prognostic signatures. Then, two novel risk signatures were constructed respectively based on six ceRNAs (ANLN, KIT, PRKAA2, NFIA, PTX3 and has-miR-148a-3p) and three immune cells (naïve B cells, regulatory T cells and Neutrophils). Kaplan-Meier (K-M) analysis and Cox regression analysis further proved that these two signatures were significant prognostic factors independent of multiple clinicopathological characteristics. Two nomograms were built based on ceRNAs-riskScore and TIICs-riskScore that could be used to predict the prognosis of HNSCC. Co-expression analysis showed significant correlations between miR-148a-3p and naive B cells, naive B cells and plasmas cells. Conclusion: Through construction of the ceRNA network and estimation of TIICs, we established two risk signatures and their nomograms with excellent utility, which indicated the potential molecular and cellular mechanisms, and predicted the prognosis of HNSCC.

Abstract
In this article, we highlight the evolution of a multimodal approach in the overall management of squamous cell carcinoma of the head and neck (SCCHN) in India; present advances in technology (newer surgical techniques), novel medical and radiotherapy (RT) approaches; review their roles for an integrated approach for treating SCCHN and discuss the current role of immunotherapy in SCCHN. For locally advanced (LA) SCCHN, the multidisciplinary approach includes surgery followed by RT, with or without chemotherapy (CT) or concurrent chemoradiotherapy. Improved surgical techniques of reconstruction and voice-preservation are being implemented. Advanced forms of high-precision conformal techniques like intensity-modulated radiotherapy are used to deliver highly conformal doses to tumors, sparing the surrounding normal tissue. Compared with RT alone, novel CT regimens and targeted therapeutic agents have the potential to improve locoregional control and survival and reduce treatment-induced toxicities. Several clinical trials have demonstrated efficacy, safety, and quality of life benefits of adding cetuximab to RT regimens in LASCCHN. Studies have also suggested a cetuximab-related laryngeal preservation benefit. At progression, platinum-based CT combined with cetuximab (a monoclonal anti-epidermal growth factor receptor antibody) is the only validated option available as the first-line therapy. Thus, an integrated multidisciplinary approach plays a key role in maximizing patient outcomes, reduction in treatment related morbidities that consequently impact quality of life of survivors.

Abstract
This study demonstrated the usefulness of radiomic features based on the Hessian index of differential topology for the prediction of prognosis prior to treatment in head-and-neck (HN) cancer patients. The Hessian index, which can indicate tumor heterogeneity with convex, concave, and other points (saddle points), was calculated as the number of negative eigenvalues of the Hessian matrix at each voxel on computed tomography (CT) images. Three types of signatures were constructed in a training cohort (n = 126), one type each from CT conventional features, Hessian index features, and combined features from the conventional and index feature sets. The prognostic value of the signatures were evaluated using statistically significant difference (p value, log-rank test) to compare the survival curves of low- and high-risk groups. In a test cohort (n = 68), the p values of the models built with conventional, index, combined features, and clinical variables were 2.95 [Formula: see text] 10-2, 1.85 [Formula: see text] 10-2, 3.17 [Formula: see text] 10-2, and 1.87 [Formula: see text] 10-3, respectively. When the features were integrated with clinical variables, the p values of conventional, index, and combined features were 3.53 [Formula: see text] 10-3, 1.28 [Formula: see text] 10-3, and 1.45 [Formula: see text] 10-3, respectively. This result indicates that index features could provide more prognostic information than conventional features and further increase the prognostic value of clinical variables in HN cancer patients.
