    ABSTRACT: Human epidermal growth factor receptor 3 (HER3) is a member of the human epidermal growth factor receptor (HER) family. The main characteristic of HER3 is that it does not possess tyrosine kinase activity, unlike other HERs. The role of HER3 in tumorigenesis has now been recognized, particularly in head and neck squamous cell carcinomas (HNSCCs). Despite conflicting studies, HER3 was found to be overexpressed in HNSCC samples, and correlates with disease progression and poor survival, especially when it is coexpressed with other HERs. HER3 is a significant factor in HNSCC treatment resistance. Indeed, HER3 is a major mechanism described for cetuximab resistance because of modification of epidermal growth factor receptor (EGFR) internalization and by phosphotidylinositol-3-kinase (PI3K)/AKT signaling pathway activation. HER3 also affects resistance to tyrosine kinase inhibitors (TKIs) and thereby promotes treatment escape and radiotherapy resistance by activation of the survival signaling pathway. To counteract this, pharmacologic inhibitors of HER3 are currently in development and could significantly improve HNSCC treatment. © 2016 Wiley Periodicals, Inc. Head Neck, 2016.

    ABSTRACT: Introduction: Lemierre syndrome is a complication of oropharyngeal infection and consists of a combination of internal jugular vein septic thrombophlebitis with septicaemia and distant septic emboli (mainly in the lungs). We describe an atypical case with facial vein and anterior jugular vein thrombophlebitis. Case summary: A 34-year-old woman attended the emergency room with tonsillitis, left head and neck cellulitis, left facial vein thrombosis and lung abscesses. A diagnosis of atypical Lemierre syndrome was proposed and the patient was treated surgically (neck incision and tonsillectomy) and medically (antibiotics, hyperbaric oxygen therapy and anticoagulation) allowing cure without sequelae. Discussion: Lemierre syndrome, a rare but serious complication requiring immediate treatment, should be investigated (by blood cultures and chest CT scan) in the presence of neck vein thrombosis complicating oropharyngeal infection.

    ABSTRACT: The authors present the guidelines of the French Otorhinolaryngology - Head and Neck Surgery Society (SFORL) for patient pathway organization in head and neck cancer, and in particular for multidisciplinary team meetings. The present article concerns the therapeutic decision-making process. A multidisciplinary work group was entrusted with a review of the scientific literature on the above topic. Guidelines were drawn up, based on the articles retrieved and the group members' individual experience. They were then read over by an editorial group independent of the work group. The final version was established in a coordination meeting. The guidelines were graded as A, B, C or expert opinion, by decreasing level of evidence. It is recommended that: an organ specialist should contribute to all multidisciplinary meetings on head and neck cancer; all members of the multidisciplinary meeting should have specific knowledge in head and neck cancer; any referring physician who does not follow the multidisciplinary meeting's advice should justify that decision; there should be sufficient time to prepare, discuss and sum up the cases dealt with in the multidisciplinary team meeting.

    ABSTRACT: To delineate the histopathological characteristics of nasal mucosa in refractory chronic rhinosinusitis with nasal polyps (CRSwNP) in order to demonstrate subtypes of nasal polyps and their potential relation with lower airway comorbidity. Clinical- and pathological-based cross-sectional study Methods: Nasal polyp specimens were prospectively collected from patients with refractory CRSwNP referred to our institution for endoscopic sinus surgery. Oral and topical steroids were stopped 1 month before surgery. The pathological analysis was conducted by 2 independent reviewers with light microscopy on Hematoxylin-Eosin-Saffron stained slides. Each observer fulfilled a standardized protocol with cell count and stromal characterization on the most representative field. Mean grading scores were established. Morphological aspects were compared with the cell distribution and the clinical conditions. Among 36 patients, three subtypes of nasal polyps were depicted: eosinophilic edematous (64%), fibrous (9%) and intermediate with mixed edematous and collagen stromal structure (27%). Basement membrane thickening and seromucous gland hyperplasia were observed in the fibrosis sub-type (p<0.03). Eosinophilic mucosal infiltrate was significantly increased (p=0.026) in patients with concomitant pulmonary disease (n=21). Nasal polyp distribution was not influenced by asthma, allergy, previous surgery and smoking. Our 3-subtype classification of refractory CRSwNP in Caucasian population shows a predominant edematous structure whatever the clinical conditions may have been. Eosinophilia as a major factor of adaptive immune response in nasal inflammation is a feature of concomitant pulmonary disease. Further studies concerning mucosal remodelling and outcome assessment after sinus surgery are required to evaluate the impact of our classification on a daily basis.

    ABSTRACT: Treatment of infected nasal polyposis. Multicenter interventional prospective double-blind randomized study with matched groups: treatment with tobramycin aerosol versus isotonic saline aerosol. The study population included 55 patients: 23 receiving isotonic saline aerosol and 32 receiving tobramycin. A novel device (Easynose(®)) was used with an original principle limiting pulmonary deposition and ensuring homogeneous peripheral deposition in the nasal cavities. The principal objective was to compare bacteriological eradication between tobramycin 150mg/3ml versus isotonic saline, both administered by nebulization via the Easynose(®) device. Tobramycin aerosol administered via the Easynose(®) device showed significantly better bacteriological eradication than isotonic saline. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

    ABSTRACT: To assess subjective improvement of olfactory function following endoscopic sinus surgery (ESS) in chronic rhinosinusitis associated with nasal polyps (CRSwNP) and to analyse factors of recovery with the European Test of Olfactory Capabilities (ETOC). We carried out a prospective study of 30 patients with CRSwNP from November 2011 to April 2013. The ETOC was filled the day before surgery and in the short term follow-up. Sixteen suprathreshold odorants with a detection task and a forced choice verbal identification task were tested. The mean composite score (MCS) improved at 3 and 6 months. The preoperative MCS was correlated to the Lund-Mackay score and to the olfactory cleft opacification on preoperative computed tomography (CT) scan. Multivariate linear regression modelling of patients with preoperative anosmia showed that the olfactory recovery at 3 months was predicted by the preoperative Lund-Mackay score and the age, and at 6 months by the preoperative Lund-Mackay score. With a convenient psychophysical test, we showed that olfactory cleft opacification and CT scan score could be predictive factors of olfaction disorder severity and improvement after ESS in CRSwNP. These results need to be strengthened in the long term with a larger panel of patients.

    ABSTRACT: Chronic rhinosinusitis with nasal polyps (CRSwNP) is frequently associated with asthma. Mucosal eosinophil (EO) infiltrate has been found to correlate with asthma and disease severity but not necessarily in every patient. Other multifactorial immune processes are required to determine disease endotypes and response to treatment. To evaluate EO immunomodulation for migration and survival in accordance with inflammatory protein profiles and asthmatic status in CRSwNP. Ninety-three patients (47 with asthma) with CRSwNP were included. Each patient was staged clinically according to symptom severity and polyp size. Nasal secretions were collected to establish a cytokine profile. The EOs were purified from blood samples and nasal polyps to delineate specific immunophenotypes by flow cytometry and determine in vitro EO survival in relation to asthmatic status. The CRSwNP in patients with asthma was characterized by eosinophilia and a high level of interleukin (IL)-5 in nasal secretions. Although EOs exhibited activation profiles after mucosal migration, there was relative down-expression of IL-5 receptor-α (IL-5Rα) on nasal EOs in patients with asthma. The EO culture with IL-5 and IL-9 showed an antiapoptotic effect in patients with asthma through IL-5Rα modulation. Mucosal eosinophilia seems to be induced by EO nasal trapping through modulation of adhesion receptors. In patients with asthma, EO involvement is enhanced by the antiapoptotic synergistic action of T-helper cell type 2 cytokines on IL-5Rα expression. This study shows for the first time that IL-9 is involved in EO homeostasis in CRSwNP and could explain the low benefit of anti-IL-5 therapy for some patients with asthma and nasal polyposis.

    ABSTRACT: Objective The study was designed to assess the prevalence, management and survival of patients with simultaneous squamous cell carcinomas of the oral cavity and hypopharynx (OC/HP). Material and methods A multicenter, retrospective study (2 university hospitals) was conducted between 2003 and 2007 on a series of 96 patients with simultaneous squamous cell cancers of the OC/HP. Results A total of 88 men and 8 women were included in the study: 81 patients presented double sites, 14 presented triple sites and one presented quadruple sites. The tumour sites most frequently observed were: hypopharynx in 61% of cases (involving the pyriform sinus in 42% of cases) and the oropharynx in 59% of cases (involving the palatine tonsil in 30% of cases). Upper aerodigestive tract endoscopy under general anaesthesia revealed a simultaneous lesion not suspected on clinical examination in 45% of patients: the site discovered on endoscopy was hypopharyngeal in 2 out of 3 cases; the tumour was classified T1 or T2 in 95.5% of cases. Patients treated simultaneously for all sites had a better prognosis than patients in whom each tumour was treated separately. The 5-year specific survival was 34% and the 5-year overall survival was 28%. Conclusion The prevalence of simultaneous squamous cell carcinomas of the oral cavity and hypopharynx ranges between 1 to 7.4% in the literature and was 4.6% in the present series. A common treatment strategy for each of the patient's tumours appears to be superior to the current theoretical approach that consists of considering each tumour separately.

    ABSTRACT: Background: Sinonasal cancers are rare and associated with a poor prognosis. The purpose of this study was to report our experience and analyze the risk factors for oncologic failures. Methods: A retrospective review of 156 consecutive patients treated with curative intent for sinonasal malignancy between 1995 and 2005 at tertiary cancer center was performed. Demographic, clinical, morphological, and pathological parameters were correlated with oncologic outcomes. Results: Complete response was obtained for 134 patients. Sixty-eight patients relapsed, among which 51 had local recurrence. Nine of these 51 patients (17.6%) underwent successful salvage therapy. Five-year local failure and overall survival rates were 50.0% and 61.1%, respectively. Maxillary sinus tumors, intracranial invasion, and N > 0 classification at initial diagnosis were significantly and independently associated with local failure and survival in multivariate analysis. Conclusion: Local control after initial treatment is primordial to optimizing outcomes because of the poor results of salvage therapy.

    ABSTRACT: We present herein the proposal of the European Laryngological Society working committee on nomenclature for a systematic classification of open partial horizontal laryngectomies (OPHL). This is based on the cranio-caudal extent of laryngeal structures resected, instead of a number of different and heterogeneous variables present in existing nomenclatures, usually referring to eponyms, types of pexy, or inferior limit of resection. According to the proposed classification system, we have defined three types of OPHLs: Type I (formerly defined horizontal supraglottic laryngectomy), Type II (previously called supracricoid laryngectomy), and Type III (also named supratracheal laryngectomy). Use of suffixes "a" and "b" in Type II and III OPHLs reflects sparing or not of the suprahyoid epiglottis. Various extensions to one arytenoid, base of tongue, piriform sinus, and crico-arytenoid unit are indicated by abbreviations (ARY, BOT, PIR, and CAU, respectively). Our proposal is not intended to give a comprehensive algorithm of application of different OPHLs to specific clinical situations, but to serve as the basis for obtaining a common language among the head and neck surgical community. We therefore intend to present this classification system as a simple and intuitive teaching instrument, and a tool to be able to compare surgical series with each other and with non-surgical data.

    ABSTRACT: It is accepted that the follow-up of patients who had treatment for laryngeal cancer is a fundamental part of their care. The reasons of post-treatment follow-up include evaluation of treatment response, early identification of recurrence, early detection of new primary tumours, monitoring and management of complications, optimisation of rehabilitation, promotion smoking and excessive alcohol cessation, provision of support to patients and their families, patient counselling and education. Controversies exist in how these aims are achieved. Increasing efforts are being made to rationalise the structure and timing of head and neck cancer follow-up clinics. The aim of this document is to analyse the current evidence for the need to follow up patients who have been treated for LC and provide an up to date, evidence-based statement which is meaningful and applicable to all European Health Care Systems. A working group of the Head and Neck Cancer Committee of the ELS was constituted in 2009. A review of the current published literature on the management and follow-up of laryngeal cancer was undertaken and statements are made based on critical appraisal of the literature and best current evidence. Category recommendations were based on the Oxford Centre for Evidence-Based Medicine. Statements include: length, frequency, setting, type of health professional, clinical assessment, screening investigations, patient's education, second primary tumours, and mode of treatment considerations including radiotherapy, chemo-radiation therapy, transoral surgery and open surgery. It also addresses specific recommendations regarding patients with persistent pain, new imaging techniques, tumour markers and narrow band imaging.
