Abstract
Malignant tumors of the external auditory canal are rare tumors and very often diagnosed at an advanced stage due to non-specific symptoms. The best treatment is the radical surgery, eventually followed by radiotherapy. A multidisciplinary team is essential to realize an optimal management. Prognosis remains unfavorable for advanced tumors.

Abstract
Tumor microenvironments (TMEs) influence cancer progression but are complex and often differ between patients. Considering that microenvironment variations may reveal rules governing intratumoral cellular programs and disease outcome, we focused on tumor-to-tumor variation to examine 52 head and neck squamous cell carcinomas. We found that macrophage polarity-defined by CXCL9 and SPP1 (CS) expression but not by conventional M1 and M2 markers-had a noticeably strong prognostic association. CS macrophage polarity also identified a highly coordinated network of either pro- or antitumor variables, which involved each tumor-associated cell type and was spatially organized. We extended these findings to other cancer indications. Overall, these results suggest that, despite their complexity, TMEs coordinate coherent responses that control human cancers and for which CS macrophage polarity is a relevant yet simple variable.

Abstract
BACKGROUND There have been few recent advances in the identification of occult lymph node metastases (OLNM) in oral squamous cell carcinoma (OSCC). This study aimed to develop, compare, and validate several machine learning models to predict OLNM in clinically N0 (cN0) OSCC. METHODS The biomarkers CD31 and PROX1 were combined with relevant histological parameters and evaluated on a training cohort (n = 56) using four different state-of-the-art machine learning models. Next, the optimized models were tested on an external validation cohort (n = 112) of early-stage (T1-2 N0) OSCC. RESULTS The random forest (RF) model gave the best overall performance (area under the curve = 0.89 [95% CI = 0.8, 0.98]) and accuracy (0.88 [95% CI = 0.8, 0.93]) while maintaining a negative predictive value >95%. CONCLUSIONS We provide a new clinical decision algorithm incorporating risk stratification by an RF model that could significantly improve the management of patients with early-stage OSCC.

Abstract
Local recurrence after surgery for head and neck squamous cell carcinoma (HNSCC) remains a common event associated with a dismal prognosis. Improving this outcome requires a better understanding of cancer cell populations that expand from postsurgical minimal residual disease (MRD). Therefore, we assessed clonal dynamics in a surgical model of barcoded HNSCC growing in the submental region of immunodeficient mice. Clonal substitution and massive reduction of clonal heterogeneity emerged as hallmarks of local recurrence, as the clones dominating in less heterogeneous recurrences were scarce in their matched primary tumors. These lineages were selected by their ability to persist after surgery and competitively expand from MRD. Clones enriched in recurrences exhibited both private and shared genetic features and likely originated from ancestors shared with clones dominating in primary tumors. They demonstrated high invasiveness and epithelial-to-mesenchymal transition, eventually providing an attractive target for obtaining better local control for these tumors.

Abstract
Sustained expression of FOXM1 is a hallmark of nearly all human cancers including squamous cell carcinomas of the head and neck (HNSCC). HNSCCs partially preserve the epithelial differentiation program, which recapitulates fetal and adult traits of the tissue of tumor origin but is deregulated by genetic alterations and tumor-supporting pathways. Using shRNA-mediated knockdown, we demonstrate a minimal impact of FOXM1 on proliferation and migration of HNSCC cell lines under standard cell culture conditions. However, FOXM1 knockdown in three-dimensional (3D) culture and xenograft tumor models resulted in reduced proliferation, decreased invasion, and a more differentiated-like phenotype, indicating a context-dependent modulation of FOXM1 activity in HNSCC cells. By ectopic overexpression of FOXM1 in HNSCC cell lines, we demonstrate a reduced expression of cutaneous-type keratin K1 and involucrin as a marker of squamous differentiation, supporting the role of FOXM1 in modulation of aberrant differentiation in HNSCC. Thus, our data provide a strong rationale for targeting FOXM1 in HNSCC. © 2019 Pathological Society of Great Britain and Ireland. Published by John Wiley & Sons, Ltd.

Abstract
Squamous cell carcinoma (SCC) of the head and neck is the sixth most common cancer worldwide. It is preceded by early asymptomatic lesions which, if identified early enough and removed, would prevent malignant transformation or avoid delaying diagnosis to advanced stages. Our aim was to evaluate the feasibility of a screening programme for SCC of the head and neck in a group of high-risk patients, and to investigate their addiction profile. Patients admitted to an inpatient alcohol addiction centre (n=101) were prospectively enrolled and asked to fill in a questionnaire about their use of tobacco and alcohol, and the presence of warning symptoms for SCC of the head and neck from 23 June 2014 to 21 January2016. Participants in the study had a physical examination by an alcohol addiction physician followed by a full examination of the head and neck by an otorhinolaryngologist to rule out premalignant or malignant lesions of the upper aerodigestive tract. Of the 101 patients, 62 (60%) had at least one warning symptom. Alcohol addiction physicians identified leukoplakia in six (6%) and erythroplakia in two. No pre-malignant or malignant lesions were confirmed on examination by the otolaryngologist. We were unable to draw conclusions about the cost-effectiveness or the yield of the screening programme. Despite our negative findings, we may need further investigation to clarify the relevance of such a programme on health-related outcome given the high compliance rate and minimal delay that was achieved by taking advantage of an in-patient alcohol rehabilitation centre.

Abstract
Objective The management of occult lymph node metastasis (LNM) in head and neck squamous cell carcinoma has been a matter of controversy for decades. The vascular density within the tumor microenvironment, as an indicator of ongoing angiogenesis, could constitute an attractive predictor of LNM. The use of the panvascular endothelial antibody CD31 as a marker of occult LNM has never been reported. The aim of this study was to assess the predictive value of CD31 microvascular density for the detection of occult LNM in squamous cell carcinoma of the oral cavity and oropharynx. Study Design Case series with chart review. Setting Tertiary university hospital. Subjects and Methods Intra- and peritumoral microvascular density values were determined in 56 cases of squamous cell carcinoma of the oral cavity (n = 50) and oropharynx (n = 6) with clinically negative necks using the CD31 marker. Statistical associations of CD31 microvascular densities with clinicopathologic data were then established. Results Peritumoral CD31 microvascular density was significantly associated with occult LNM in multivariate analysis ( P < .01). Recursive partitioning analysis for this parameter found a cutoff of 19.33, which identified occult LNM with a sensitivity of 91%, a specificity of 65%, a positive predictive value of 40%, a negative predictive value of 97%, and an overall diagnostic accuracy of 71%. Conclusion Peritumoral CD31 microvascular density in primary squamous cell carcinoma of the oral cavity and oropharynx allows accurate prediction of occult LNM.

Abstract
HPV-positive head and neck squamous cell carcinoma (HNSCC) is increasingly frequent. Management is particularly debated in the case of postsurgical high-risk features, that is, positive surgical margins and extracapsular spread (ECS). In this increasingly complex emerging framework of HNSCC treatment, representative preclinical models are needed to support future clinical trials and advances in personalized medicine. Here, we present an immunocompetent mouse model based on the implantation of mouse tonsil epithelial HPV16-E6/E7-expressing cancer cells into the submental region of the floor-of-the-mouth. Primary tumors were found to replicate the patterns of human HNSCC local invasion and lymphatic dissemination. To study disease progression after surgery, tumors were removed likely leaving behind residual disease. Surgical resection of tumors was followed by a high rate of local recurrences (>90%) within the first 2-3 weeks. While only 50% of mice had lymph node metastases (LNM) at time of primary tumor excision, all mice with recurrent tumors showed evidence of LNM. To study the consecutive steps of LNM progression and distant metastasis development, LNs from tumor-bearing mice were transplanted into naïve recipient mice. Using this approach, transplanted LNs were found to recapitulate all stages and relevant histological features of regional metastasis progression, including ECS and metastatic spread to the lungs. Altogether, we have developed an immunocompetent HPV-positive HNSCC mouse model of postsurgical local recurrence and regional and distant metastasis progression suitable for preclinical studies.

Abstract
INTRODUCTION Carotid artery stenosis following radiotherapy (RT) is a known risk factor for the development of cerebrovascular disease with a risk of subsequent stroke or transient ischaemic attack. In contrast, small vessel disease in the neck following RT has been more rarely described. CASE REPORT The authors report the case of a 61-year-old man who developed partial lingual necrosis 4 years after surgery and postoperative chemoradiotherapy for squamous cell carcinoma of the floor of the mouth. Contrast-enhanced CT scan confirmed subtotal to total occlusion of both lingual arteries. Surgical debridement of the necrosis allowed complete cure of the lesions. DISCUSSION Small vessel disease is a possible complication in patients treated by RT for head and neck cancer. Although the risk of these complications is not directly related to the total radiation dose, higher doses appear to accelerate the development of vascular lesions. Practitioners must be aware of the possibility of these complications, especially in patients surviving more than 5 years.

Abstract
Extracapsular spread (ECS) is one of the most important prognostic factors in head and neck squamous cell carcinoma (HNSCC). However, despite its major clinical relevance, there are still a number of important remaining issues regarding this condition. Indeed, standardized diagnostic and grading criteria of ECS are still lacking. The imaging modality of choice for its diagnosis is a matter of debate. Current research looking at the identification of specific biomarkers is ongoing. Recent findings demonstrate a direct correlation between the level of extension of ECS and a poor prognosis. Accumulating data show that ECS does not carry the same adverse features in human papilloma virus (HPV)-positive oropharyngeal squamous cell carcinoma (OPSCC). New treatment strategies based on these factors are currently considered to investigate the possibility of diminishing the toxicity of chemo-radiotherapy while maintaining similar outcomes. The goal of this article was to provide a systematic review of the literature covering all the issues related to ECS. As an additional component of the review, meta-analyses were performed on relevant aspects of ECS for which previous quantitative data were outdated or not available. The results of these meta-analyses confirm the negative impact of ECS on loco-regional recurrence and distant metastasis. They also demonstrate the absence of a negative impact of ECS in HPV-positive OPSCC.

Abstract
BACKGROUND The correlation between podoplanin expression and extracapsular spread in head and neck squamous cell carcinoma (HNSCC) has never been reported. The purpose of this study was to assess the predictive value of podoplanin expression for this parameter. METHODS Subjective immunoreactivity scores and semiquantitative image analysis of podoplanin expression were performed in 67 patients with primary oral squamous cell carcinoma and in their corresponding lymph nodes. Neck classification showed 34 cases (51%) of pN0 and 33 cases (49%) of pN+. Correlation between the levels of podoplanin expression and the histopathological data was established. RESULTS In lymph nodes, a high level of podoplanin expression correlated with the presence of extracapsular spread by multivariate analysis (p = .03). A strong correlation between subjective and semiquantitative image analysis was observed (r = 0.77; p < .001). CONCLUSION A high level of podoplanin expression in lymph node metastases of oral squamous cell carcinoma is independently associated with extracapsular spread. © 2016 Wiley Periodicals, Head Neck 39: 98-108, 2017.

Abstract
BACKGROUND The effectiveness of transoral microsurgery for early-stage glottic cancer relies on the possibility to obtain adequate exposure of the lesion. The purpose of this study was to design a new surgical technique allowing efficient endoscopic removal of these tumors in patients with unsatisfactory transoral exposure. METHODS A minimal invasive access to the glottis, made through the thyrohyoid membrane and the preepiglottic space, was used for endoscopic resection of an early-stage glottic tumor in a patient with a medical history of previous radiotherapy and unsatisfactory endoscopic exposure of the lesion. RESULTS This approach provided excellent exposure of the glottis and allowed endoscopic resection with adequate surgical margins. The surgical procedure and the postoperative period were uneventful. Functional outcomes were back to baseline after 1 month. CONCLUSION This technique represents an attractive solution for patients presenting with early-stage glottic tumors that cannot be exposed transorally and have contraindications to alternative therapeutic procedures. © 2016 Wiley Periodicals, Inc.

Abstract
Airway stenting is a common endoscopic procedure that is used to treat a variety of central airway lesions. Obstructions or fistulas involving the carina or nearby tracheobronchial structures require the use of specially designed stents, commonly referred to as Y-stents. Conventional methods of endobronchial Y-stent delivery are all characterized by a blind and apneic period during the procedure that carries the risk of stent misplacement or ventilation/oxygenation problems or both. Using combined suspension laryngoscopy, flexible bronchoscopy, and jet ventilation, we describe a technique that makes challenging bronchoscopic interventions--such as self-expandable Y-shaped airway stent delivery--easy, precise, and safe.

Abstract
Bilateral congenital vocal fold paralysis (BVFP) may result from multiple etiologies or remain idiopathic when no real cause can be identified. If obstructive dyspnea is significant and requires urgent stabilization of the airway, then intubation is performed first and an MRI of the brain is conducted to rule out an Arnold-Chiari malformation that can benefit from a shunt procedure and thus alleviate the need for a tracheostomy. Clinically silent subdural hemorrhage without any birth trauma represents another cause of neonatal BVFP that resolves spontaneously within a month. It is of clinical relevance to recognize this potential cause of BVFP as its short duration may alleviate the need for a tracheostomy. In this article, we present such a case and review the literature to draw the otolaryngologist's attention to this possible etiology.

Abstract
Objective. Mandibular osteoradionecrosis (ORN) is a serious complication of radiotherapy (RT) in head and neck cancer patients. The aim of this study was to analyze the incidence of and risk factors for mandibular ORN in squamous cell carcinoma (SCC) of the oral cavity and oropharynx. Study Design. Case series with chart review. Setting. University tertiary care center for head and neck oncology. Subjects and Methods. Seventy-three patients treated for stage I to IV SCC of the oral cavity and oropharynx between 2000 and 2007, with a minimum follow-up of 2 years, were included in the study. Treatment modalities included both RT with curative intent and adjuvant RT following tumor surgery. The log-rank test and Cox model were used for univariate and multivariate analyses. Results. The incidence of mandibular ORN was 40% at 5 years. Using univariate analysis, the following risk factors were identified: oral cavity tumors ( P < .01), bone invasion ( P < .02), any surgery prior to RT ( P < .04), and bone surgery ( P < .0001). By multivariate analysis, mandibular surgery proved to be the most important risk factor and the only one reaching statistical significance ( P < .0002). Conclusion. Mandibular ORN is a frequent long-term complication of RT for oral cavity and oropharynx cancers. Mandibular surgery before irradiation is the only independent risk factor. These aspects must be considered when planning treatment for these tumors.

Abstract
Radiotherapy is widely used to treat human cancer. Patients locally recurring after radiotherapy, however, have increased risk of metastatic progression and poor prognosis. The clinical management of postradiation recurrences remains an unresolved issue. Tumors growing in preirradiated tissues have an increased fraction of hypoxic cells and are more metastatic, a condition known as tumor bed effect. The transcription factor hypoxia inducible factor (HIF)-1 promotes invasion and metastasis of hypoxic tumors, but its role in the tumor bed effect has not been reported. Here, we show that tumor cells derived from SCCVII and HCT116 tumors growing in a preirradiated bed, or selected in vitro through repeated cycles of severe hypoxia, retain invasive and metastatic capacities when returned to normoxia. HIF activity, although facilitating metastatic spreading of tumors growing in a preirradiated bed, is not essential. Through gene expression profiling and gain- and loss-of-function experiments, we identified the matricellular protein CYR61 and alphaVbeta5 integrin as proteins cooperating to mediate these effects. The anti-alphaV integrin monoclonal antibody 17E6 and the small molecular alphaVbeta3/alphaVbeta5 integrin inhibitor EMD121974 suppressed invasion and metastasis induced by CYR61 and attenuated metastasis of tumors growing within a preirradiated field. These results represent a conceptual advance to the understanding of the tumor bed effect and identify CYR61 and alphaVbeta5 integrin as proteins that cooperate to mediate metastasis. They also identify alphaV integrin inhibition as a potential therapeutic approach for preventing metastasis in patients at risk for postradiation recurrences.

Abstract
Maxillary sinusitis are common infections. A dental origin is found in about 10% of the cases. The roots of the posterior maxillary teeth are adjacent to the sinus floor. Extensions of dental infections are therefore possible to the sinus. An odontogenic source should be considered in patients with a history of dental pain or recent oral surgery and those with extended unilateral sinusitis or unilateral sinusitis resistant to conventional treatment. Maxillary sinusitis of dental origin are polymicrobial infections. Conventional radiographs and CT-scans are required for the diagnosis and proper management. Dental treatments to remove the underlying cause combined with oral antibiotics to treat the infection are required. Endoscopic or open surgery may be necessary to complete the treatment and restore adequate sinusal function.

Abstract
Early complications of myocutaneous flap transfers following surgical eradication of head and neck tumors have been extensively described. However, knowledge concerning long-term complications of these techniques remains limited. We report the cases of two patients with a prior history of squamous cell carcinoma of the head and neck (HNSCC), who developed a second primary SCC on the cutaneous surface of their flaps, years after reconstruction. Interestingly, it seems that the well-known risk of a second primary SCC in patients with previous head and neck carcinoma also applies to foreign tissues implanted within the area at risk. Given the important expansion of these interventions, this type of complication may become more frequent in the future. Therefore, long-term follow-up of patients previously treated for HNSCC not only requires careful evaluation of the normal mucosa of the upper aero-digestive tract, but also of the cutaneous surface of the flap used for reconstruction.

Abstract
Tumor necrosis factor (TNF) is a pro-inflammatory cytokine exerting pleiotropic effects on endothelial cells. Depending on the vascular context it can induce endothelial cell activation and survival or death. The microenvironmental cues determining whether endothelial cells will survive or die, however, have remained elusive. Here we report that integrin ligation acts permissive for TNF-induced protein kinase B (PKB/Akt) but not nuclear factor (NF)-kappaB activation. Concomitant activation of PKB/Akt and NF-kappaB is essential for the survival of endothelial cells exposed to TNF. Active PKB/Akt strengthens integrin-dependent endothelial cell adhesion, whereas disruption of actin stress fibers abolishes the protective effect of PKB/Akt. Integrin-mediated adhesion also represses TNF-induced JNK activation, but JNK activity is not required for cell death. The alphaVbeta3/alphaVbeta5 integrin inhibitor EMD121974 sensitizes endothelial cells to TNF-dependent cytotoxicity and active PKB/Akt attenuates this effect. Interferon gamma synergistically enhanced TNF-induced endothelial cell death in all conditions tested. Taken together, these observations reveal a novel permissive role for integrins in TNF-induced PKB/Akt activation and prevention of TNF-induced death distinct of NF-kappaB, and implicate the actin cytoskeleton in PKB/Akt-mediated cell survival. The sensitizing effect of EMD121974 on TNF cytotoxicity may open new perspectives to the therapeutic use of TNF as anticancer agent.

Abstract
Experimental and clinical evidence indicates that non-steroidal anti-inflammatory drugs and cyclooxygenase-2 inhibitors may have anti-cancer activities. Here we report on a patient with a metastatic melanoma of the leg who experienced a complete and sustained regression of skin metastases upon continuous single treatment with the cyclooxygenase-2 inhibitor rofecoxib. Our observations indicate that the inhibition of cyclooxygenase-2 can lead to the regression of disseminated skin melanoma metastases, even after failure of chemotherapy.

Abstract
The formation of new blood vessels, a process globally referred to as angiogenesis, occurs in a number of pathological conditions, such as cancer and chronic inflammation. Recent findings indicate that cyclooxygenase-2 (COX-2), the inducible form of the cyclooxygenase (COX) isoenzymes, acts as a potent inducer of angiogenesis. Non-steroidal anti-inflammatory drugs (NSAIDs) are classical inhibitors of COX enzymes, which are widely prescribed for the treatment of inflammation, pain and fever. Selective COX-2 inhibitors (COXIBs) have been subsequently developed with the purpose to improve the safety profile of this class of therapeutics. More recently, substantial preclinical evidence demonstrated that NSAIDS and COXIBs have anti-angiogenic properties. This newly recognized activity opens the possibility of using these drugs for the treatment of angiogenesis-dependent diseases. In this article we review the most recent advances in understanding the mechanisms by which NSAIDs and COXIBs suppress angiogenesis, and we discuss their potential clinical use as anti-angiogenic drugs.
