Prevalence of obstructive sleep apnoea syndrome following oropharyngeal cancer treatment: A prospective cohort study.

OBJECTIVES: To evaluate the prevalence of obstructive sleep apnoea syndrome (OSAS) in a population of patients treated for an advanced oropharyngeal cancer (AJCC Stage III or IV), depending on treatment strategy, and to evaluate its impact on quality of life. DESIGN: Prospective cohort study. SETTING: University Teaching Hospital of La Conception, Marseille, France. PARTICIPANTS: Fifty-one disease-free patients were included. Forty-one patients received a combined chemoradiotherapy, while 10 patients were treated by surgery followed by chemoradiotherapy. MAIN OUTCOME MEASURES: Every patient underwent a formal sleep consultation and was asked to complete the Epworth Sleepiness Scale and EORTC QLQ C-30 and the EORTC H&N 35 questionnaires. A home overnight respiratory polygraphy was performed in every subject. RESULTS: The mean time between the end of cancer treatment and the OSAS analysis was 54.04 months [20; 84]. An OSAS was found in 25.49% of our patients. There was no significant difference between patients treated with either surgery (30%) or CRT (24.39%), P=.79. The EORTC QLQ C-30 questionnaire showed a significant difference between positive and negative OSAS groups in the Global Health Status Scale (50.64 vs 67.11, P=.02) and in the fatigue item (35.04 vs 17.25, P=.03). CONCLUSIONS: Our population with advanced oropharyngeal cancer, whatever the treatment strategy it may be, was at risk of developing OSAS with negative impact on quality of life. A routine screening and treatment of OSAS seems necessary to improve the quality of life of patients treated for advanced oropharyngeal cancer.

A pilot study about speech changes after partial Tucker's laryngectomy: the reduction of regressive voicing assimilation.

Partial frontolateral laryngectomy (PL) is performed to remove larynx tumor while preserving its main functions. So far, the speech changes induced by difficulties of voicing and the alterations to the vocal tract due to PL have been seldom addressed. The goal of our study was to make an acoustic analysis of regressive voicing assimilation (RVA) among patients after PL and to study the relationship with rates of speech. A retrospective study was conducted from January to April 2013. 11 subjects treated by partial frontolateral laryngectomy, and ten healthy subjects were included. Functional recordings of voice were analyzed and compared. For assimilation sequences we found a significant modification of voicing ratio in healthy subjects (p < 0.05) and PL patient at accelerated speaking rate only (p < 0.05). The vowel duration is significantly modified only for healthy subjects. For all subjects (PL patients and healthy) the duration of C1 consonant was not significantly modified. Our results highlight the presence of RVA in healthy subjects, but also in PL patients in the rapid speaking mode.

[Lymphatic drainage of skin areas of head and neck: in vivo approach by the location of the sentinel node]. / Drainage lymphatique des territoires cutanés de la tête et du cou : approche in vivo par la localisation du ganglion sentinelle.

INTRODUCTION: The objective of the study was to determine the preferential territories of drainage of skin areas of the face and neck. This knowledge can guide the strategies of diagnostic (search for primary tumor skin to cervical lymphadenopathy) and treatment (determination of the extent of neck dissection to achieve in case of skin tumor). MATERIALS AND METHODS: This is a retrospective study of the surgical procedures of sentinel node research between January 2003 and April 2011. The lymphoscintigraphic and intraoperative localization of the initial tumor site and sentinel lymph node were collected. RESULTS AND DISCUSSION: One hundred and thirty-seven patients were included in the study. The parotid gland is a privileged territory of drainage of the head and neck skin. At cervical level, the submental region drains the lower and median part of the face (lips and chin). The posterior segments (IIb and V sector) were represented for the posterior locations of the head (ear, vertex), and cervical region.

[Study of tongue pressure on the hard palate during exercises of swallowing rehabilitation]. / Etude de la pression de la langue sur le palais osseux au cours desexercices de rééducation de la déglutition.

INTRODUCTION: The exercises performed during the reeducation of swallowing seek to improve forces of propulsion of the bolus and airway protection during the course of swallowing. The objective of this study was to objectify the effect of pronunciation praxis of posterior phonemes /aka/ and /akra/, and swallowing maneuvers (super-supraglottic swallow with or without superimposed effort swallowing effort) on the time of the oral swallowing. MATERIALS AND METHODS: Four healthy volunteers participated in the experiment. They are called "experts" because they have a good knowledge of physiology and rehabilitation of swallowing. The dynamic palatography setup measured continuously the different pressures from the tongue on the hard palate through three force sensors arranged in a sagittal plane during the implementation of articulatory and swallowing tasks. RESULTS: Articulatory praxis created significant pressure on the posterior sensor for 2 of the 4 subjects. All the swallowing maneuvers increased the contact pressure and the contact duration compared to the control swallowing for the anterior and posterior pressure sensor. A large inter-individual variability was found. CONCLUSION: The complexity of instruction, the inter-individual variability in their performance, and the non-invasive nature of the instrument make the dynamic palatography a potentially useful tool in routine practice of swallowing reeducation.

Sentinel lymph node biopsy in head and neck melanoma: A single institution analysis.

INTRODUCTION: The aim of our study was to analyze a series of patients from our institution who underwent surgery for head and neck cutaneous melanoma and who received sentinel lymph node biopsy (SLNB). MATERIAL AND METHODS: A single-center observational cohort of 120 head and neck melanoma patients was investigated from 2002 to 2011. RESULTS: Among the 107 patients (89.2%) with lymph node identified during lymphoscintigraphy, at least one node was collected and analyzed in 96 patients (90.6%). A positive sentinel lymph node was found in 9.4% of patients. Our data showed higher failure rate of lymphoscintigraphic identification (11.7%), lower rate of SLN positivity (9.4%), and higher false-negative rate of SLNB (24.1%) than the usualfigures established for malignant melanomas in other locations. After a mean follow-up of 38.1 months, the disease-free survival (DFS) rate in the positive SLN group was 53% vs 75% for the negative SLN after 2 years of follow-up and 53% vs 48% after 5 years (p = 0.44). CONCLUSION: The complexity of lymphatic drainage and the anatomy of the cervical region probably accounts for a specificities which result in a lower predictive value of SLNB in head and neck melanoma than in MM in other locations.

[Role of positron emission tomography and CT with 18F-FDG PET-CT in follow-up of patients treated for head and neck squamous cell carcinoma]. / Place de la 18F-FDG TEP-TDM dans la surveillance post-thérapeutique des carcinomes épidermoïdes des voies aérodigestives supérieures.

The authors in this article, made from a review of the scientific literature (PubMed search engine), indicate the current position of positron emission tomography with 18F-fluro-2-deoxy-D-glucose coupled computed tomography (PET-CT) in the early and late post-treatment follow up of squamous cell carcinomas of the upper aerodigestive tract. The aim of this follow up is twofold: Early detection of locoregional progressive evolution or metastatic progression and search for a possible second metachronous cancer in patients at risk.

Cytopathological analysis of salivary gland cancer: REFCOR recommendations by the formal consensus method.

OBJECTIVE: To determine the indications for fine-needle cytology and the modalities of frozen section pathological analysis in the management of salivary gland cancer. MATERIAL AND METHODS: The French Network of Rare Head and Neck Tumors (REFCOR) formed a steering group who drafted a narrative review of the literature published on Medline and proposed recommendations. The level of adherence to the recommendations was then assessed by a rating group according to the formal consensus method. RESULTS: Fine-needle cytology is recommended as part of the diagnostic work-up for a major salivary gland tumor suspicious for malignancy. Fine-needle cytology should be performed after MRI to avoid artifacts. Frozen section analysis is recommended to confirm the malignant nature of the tumor, to adapt the extent of resection and to indicate neck dissection. Whenever possible, the entire tumor and adjacent salivary or periglandular tissue should be sent for frozen section analysis. CONCLUSION: Fine-needle cytology and frozen section analysis play an essential role in the management of salivary gland cancers.

Diagnostic imaging of salivary gland cancers: REFCOR recommendations by the formal consensus method.

OBJECTIVE: To define the indications for each imaging modality in the screening, characterization, extension and follow-up of salivary gland tumors. MATERIAL AND METHODS: The French Network of Rare Head and Neck Tumors (REFCOR) formed a steering group who drafted a narrative review of the literature published on Medline and proposed recommendations. The level of adherence to the recommendations was then assessed by a rating group, according to the formal consensus method. RESULTS: If a swelling of a salivary gland is palpable for 3 weeks, an ultrasound scan is recommended to confirm a tumoral lesion and rule out differential diagnoses. For a salivary gland tumor, MRI is recommended with diffusion-weighted and dynamic contrast-enhanced techniques. In the case of histologically proven malignancy or a highly suspicious lesion, a CT scan of the neck and chest is recommended to assess the tumor, lymph nodes and metastases. FDG-PET is not currently recommended in routine clinical practice for initial diagnosis, assessment of extension, evaluation of response to treatment, staging of recurrence, or follow-up of salivary gland tumors. CONCLUSION: Assessing salivary tumors is based on MRI. Extension assessment is based on neck and chest CT.

Writing in the European Annals of Otorhinolaryngology Head & Neck Diseases. Dos and Don'ts!

Too many articles are still rejected by scientific medical journals due to lack of preparation of the manuscript and of knowledge of the modern editorial rules that govern scientific medical writing. Therefore, the editorial board of the European Annals of Otorhinolaryngology Heads & Neck Diseases summarized studies published by its members since 2020 in the columns of the scientific journal of the French Society of Otorhinolaryngology and the International Francophone Society of Otorhinolaryngology and data from the PubMed indexed literature dedicated to scientific medical writing in otolaryngology in the 21st century. The authors hope that this review, in the form of a list of "Dos and Don'ts", will provide authors with a practical guide facilitating publication of rigorous, reproducible and transparent scientific studies, in accordance with the movement toward better science that society as a whole has been fighting for since the beginning of this century.

[Presentation of a prototype dynamic palatography for measuring the downforce of the tongue on the palate in the swallowing time]. / Présentation d'un prototype de palatographie dynamique pour la mesure de la force d'appui de la langue sur le palais lors du temps buccal de la déglutition.

The position of the tongue and the forces which it exerts on its dental and osseous environment would be responsible for a certain degree of dysmorphosis. However there is not tool usable in clinic which makes it possible to check the reality of the forces exerted by the tongue on the palate. We developed a prototype made up of an artificial palate in rigid resin including of pressure sensors and we report the feasibility of a study on healthy subjects. The sensors allow indeed of following dynamic visible differences between various "maneuvers" during the swallowing of a water mouthful. The tool will be now adapted for a clinical study comparing of the subjects with and without lingual dysfunction

[Prognostic value of sentinel lymph node in Merkel cell carcinoma of the head and neck]. / Intérêt pronostique du ganglion sentinelle dans les carcinomes a cellules de Merkel de la tête et du cou.

INTRODUCTION: Merkel cell carcinoma (MCC) is a rare neuroendocrine skin tumor. The aim of our study was to analyze the prognosis of patients operated on for CCM and having no lymph node involvement after analysis of sentinel lymph node (SLN). MATERIAL AND METHOD: This was a retrospective study of 10 cases of CCM stage I or II who received the SLN technique in our institution between 2003 and 2010. RESULTS Among the 10 patients, 7 had an identification of at least one SLN, among which the node could be surgically removed in 6 cases. In cases of failure of SLN technique, a neck dissection +/- parotidectomy was performed. No lymph node metastasis was found in our series. Mean follow-up was 38 months. The overall survival rate was 100% at 2 years and 50% at 5 years. The Disease-free survival was 85% at 2 and 5 years. CONCLUSION: Our results show that the technique of sentinel lymph node is a reliable tool for evaluating nodal status of patients with CCM and that pN0 patients have a good prognosis.

Themistocles Gluck and the premises of modern total laryngectomy.

The aim of this historical vignette is to recall the importance of the German surgeon Themistocles Gluck in the development of total laryngectomy with primary closure of the pharyngeal orifice, a technique proposed a few years after Theodor Billroth's first total laryngectomy in 1873.

Surgery of sublingual and minor salivary gland cancer: REFCOR recommendations by the formal consensus method.

OBJECTIVE: To determine the indications and modalities for resection in the management of primary sublingual and minor salivary gland cancer, and the specific features of each primary location. MATERIAL AND METHODS: The French Network of Rare Head and Neck Tumors (REFCOR) formed a steering group who drafted a narrative review of the literature published on Medline and proposed recommendations. The level of adherence to the recommendations was then assessed by a rating group, according to the formal consensus method. RESULTS: Histological evidence (submucosal biopsy) is recommended before surgical treatment of minor salivary gland carcinoma. Surgical treatment is recommended, with optimal oncologic margins, adapted to anatomical factors, histologic type and grade and functional consequences, with reconstruction if necessary. CONCLUSION: Treatment of primary minor salivary and sublingual gland cancer is surgical, with wide resection margins. The modalities of resection and reconstruction are highly dependent on tumor location, extension and histologic type.

Lymph node surgery for salivary gland cancer: REFCOR recommendations by the formal consensus method.

OBJECTIVE: To determine the indications for neck dissection in the management of parotid, submandibular or minor salivary gland cancers depending on the clinical situation: i.e., clinical lymph node involvement (cN+) or not (cN0); low or high risk of occult nodal metastasis; diagnosis of malignancy before, during or after surgery. MATERIAL AND METHODS: The French Network of Rare Head and Neck Tumors (REFCOR) formed a steering group which drafted a narrative review of the literature published on Medline and proposed recommendations. The level of adherence to the recommendations was then assessed by a rating group according to the formal consensus method. RESULTS: In cN+ salivary gland cancer, ipsilateral neck dissection is recommended. In cN0 salivary gland cancer, ipsilateral neck dissection is recommended, except for tumors at low risk of occult nodal metastasis. If definitive pathology reveals a high risk of occult nodal involvement, additional neck treatment is recommended: ipsilateral neck dissection or elective nodal irradiation. CONCLUSION: The rate of occult lymph node involvement, and therefore the indication for elective neck dissection, depends primarily on the pathologic grade of the salivary gland cancer.

Surgery of major salivary gland cancers: REFCOR recommendations by the formal consensus method.

OBJECTIVE: To determine the role of surgery of the primary tumor site in the management of primary major salivary gland cancer. MATERIAL AND METHODS: The French Network of Rare Head and Neck Tumors (REFCOR) formed a steering group, which drafted a non-systematic narrative review of the literature published on Medline, and proposed recommendations. The level of adherence to the recommendations was then assessed by a rating group, according to the formal consensus method. RESULTS: Treatment of salivary gland tumor is mainly surgical. The gold standard for parotid cancer is a total parotidectomy, to obtain clear margins and remove all intraparotid lymph nodes. For low-grade tumors, partial parotidectomy with wide excision of the tumor is acceptable in the case of postoperative diagnosis on definitive histology. In the event of positive margins on definitive analysis, revision surgery should be assessed for feasibility, and performed if possible. CONCLUSION: Treatment of primary major salivary gland cancer is based on surgery with clear resection margins, as far away as possible from the tumor. The type of surgery depends on tumor location, pathologic type and extension.

Systemic therapies for salivary gland carcinoma (excluding adenoid cystic carcinoma): REFCOR recommendations by the formal consensus method.

OBJECTIVE: To determine the therapeutic indications for systemic medical treatment in the management of salivary gland carcinoma (excluding adenoid cystic carcinoma) according to the clinical situation. MATERIALS AND METHODS: The French Network of Rare Head and Neck Tumors (REFCOR) formed a steering group who drafted a narrative review of the literature published on Medline and proposed recommendations. The level of adherence to the recommendations was then assessed by a rating group, according to the formal consensus method. RESULTS: Salivary gland carcinoma is rare and there is currently insufficient evidence to indicate chemotherapy at the localized stage. At the metastatic stage, initial management can be based on a phase of monitoring for indolent disease. Some histological subtypes (salivary duct carcinoma and adenocarcinoma) are more aggressive and require systemic treatment from the outset. To guide systemic treatment, it is recommended to perform immunohistochemistry and molecular biology analyses (overexpression of HER2 and androgen receptors, NTRK fusion, next-generation sequencing). CONCLUSION: Salivary gland carcinoma is a rare tumor for which there are currently few effective medical treatments. It is therefore recommended to include patients in clinical trials.

Post-treatment monitoring of salivary gland cancer: REFCOR recommendations by the formal consensus method.

OBJECTIVE: To determine the frequency and modality of post-treatment monitoring of primary salivary gland cancer. MATERIAL AND METHODS: The French Network of Rare Head and Neck Tumors (REFCOR) formed a steering group who drafted a narrative review of the literature published on Medline and proposed recommendations. The level of adherence to the recommendations was then assessed by a rating group, according to the formal consensus method. RESULTS: Clinical monitoring should be adapted to the risk of recurrence: initially every 3 months and progressively spaced out, becoming annual after 5 years. Post-treatment head and neck and chest imaging is recommended at 3 months. Local and regional monitoring can then be carried out yearly or twice yearly with contrast-enhanced head and neck imaging. An annual chest CT scan is recommended for high-grade tumors. For lesions at high risk of late recurrence, very prolonged annual surveillance (up to 15 years) is recommended, including screening for pulmonary metastases. CONCLUSION: Given the wide range of malignant salivary gland tumors, the modalities and frequency of post-treatment monitoring must be adapted to the expected course of the disease.

Radiotherapy for salivary gland cancer: REFCOR recommendations by the formal consensus method.

OBJECTIVE: To determine the indications for radiotherapy in salivary gland cancer and to specify the modalities and target radiation volumes. MATERIAL AND METHODS: The French Network of Rare Head and Neck Tumors (REFCOR) formed a steering group which drafted a narrative review of the literature published on Medline and proposed recommendations. The level of adherence to the recommendations was then assessed by a rating group, according to the formal consensus method. RESULTS: Postoperatively, radiotherapy to the primary tumor site±to the lymph nodes is indicated if one or more of the following adverse histoprognostic factors are present (risk>10% of locoregional recurrence): T3-T4 category, lymph node invasion, extraglandular invasion, close or positive surgical margins, high tumor grade, perineural invasion, vascular emboli, and/or bone invasion. Intensity-modulated radiation therapy (IMRT) is the gold standard. For unresectable cancers or inoperable patients, carbon ion hadrontherapy may be considered. CONCLUSION: Radiotherapy in salivary gland cancer is indicated in postoperative situations in case of adverse histoprognostic factors and for inoperable tumors.

Systemic therapies for salivary gland cancer: Adenoid cystic carcinoma. REFCOR recommendations by the formal consensus method.

OBJECTIVE: To determine the therapeutic indications for systemic medical treatment in the management of adenoid cystic carcinoma (ACC) according to the clinical situation. MATERIALS AND METHODS: The French Network of Rare Head and Neck Tumors (REFCOR) formed a steering group, which drafted a narrative review of the literature published on Medline and proposed recommendations. The level of adherence to the recommendations was then assessed by a rating group, according to the formal consensus method. RESULTS: ACCs are rare tumors and there is currently insufficient evidence to indicate chemotherapy at the localized stage. At the metastatic stage, progression is often slow. In case of oligometastatic ACC, local treatment should be discussed. The most often indolent nature of polymetastatic ACC can allow management by active surveillance. Molecular screening is recommended, for abnormalities potentially accessible to targeted therapy. CONCLUSION: ACCs are rare tumors for which there are currently few effective medical treatments. It is therefore recommended to include patients in clinical trials.

Keys for successful publication in Eur Ann Otorhinolaryngol Head Neck Dis: A STROBE analysis of peer reviews of articles submitted in 2020-2021.

OBJECTIVE: To evaluate reviewing and editorial decision for articles submitted to the European Annals of Otorhinolaryngology Head & Neck Diseases. MATERIALS AND METHODS: A retrospective analysis was made of reviewers' comments on 1,133 scientific articles (700 original articles, 96 literature reviews, and 337 case reports), originating from 69 countries, consecutively submitted on-line between January 1st, 2020 and December 31st, 2021. The main objective was to document the acceptance rate and decision time. Accessory objectives were to synthesize the main comments and to screen for correlations between acceptance and the main characteristics of first authors, articles and reviewers' comments. RESULTS: In total, 4.1% of submitted articles were accepted. Median decision time differed significantly (P<0.0001), at 1 month in case of refusal and 4 months in case of acceptance. Reviewers mentioned failure to adhere to the journal's authors' guide, to use the appropriate EQUATOR guidelines and to adopt the recommended P<0.005 significance threshold in 94.8%, 54.2%, and 39.9% of cases, respectively. On multivariate analysis, 3 variables significantly impacted acceptance, which increased from 1.3% to 44.6% (P<0.0001) when an appropriate EQUATOR guideline was used and from 0.3% to 57.4% (P<0.0001) when the significance threshold was set at P<0.005, and decreased from 10.5% to 1.1% (P=0.0001) when the article did not originate from a French-speaking country (member of the Francophonie organization). CONCLUSION: Adhesion to modern scientific medical writing rules increased acceptance rates for articles in the European Annals of Otorhinolaryngology Head & Neck Diseases. Teaching modern scientific medical writing needs to be enhanced in otorhinolaryngology.
