Introduction: Salivary carcinomas of the tongue represent a therapeutic challenge as their radical excision is particularly mutilating. We aimed to study the oncologic and functional outcomes of advanced stages salivary carcinomas of the tongue., Materials and Methods: This retrospective multicentric study, based on the French national network on rare head and neck cancers (REFCOR), included all patients with a T3-T4 salivary carcinoma of the tongue, diagnosed between January 2009 and December 2018., Results: In total, 47 patients were included, of which 44.7 % underwent surgery. Histologies were mostly adenoid cystic carcinomas (61.7 %), followed by other adenocarcinomas (27.7 %) and mucoepidermoid carcinomas (10.6 %). Median follow-up duration was 63.9 months. In multivariable analysis, surgery was significantly associated with better Recurrence-Free Survival (HR = 0.23, 95 %CI [0.09;0.55]) and Local/Regional Recurrence-Free Survival (HR = 0.31, 95 %CI [0.10;0.95]). The rate of distant metastasis at the end of follow-up was 61.9 % in the surgical group and 57.7 % in the non-surgical group. The Distant Metastasis Free Survival was 54.9 % [38.3;68.7], without statistical difference between both groups. There were similar rates of definitive gastrostomies but the rate of normal oral diet at the last follow-up seemed higher in the surgery group (38.1 % vs 15.4 %)., Conclusion: Radical surgery in that population mainly aims to improve local/regional control, which may result in better long-term swallowing functions. About half of these tumors may be associated with occult distant metastasis at initial presentation. More studies are warranted to establish the role of postoperative RT and non-surgical treatment with concurrent CRT., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Author(s).

Objectives: The management of the facial nerve (FN) is a major issue in parotid cancer, especially when there is no preoperative facial palsy and FN invasion is discovered intraoperatively. The aim of this study was to assess the impact of FN resection in patients with parotid cancer abutting the FN, without pretreatment facial palsy, using a propensity score matching., Materials and Methods: Data from all patients treated between 2009 and 2020 for a primary parotid cancer abutting or invading the FN but without pretreatment facial palsy were extracted from the national multicentric REFCOR database. Three different definitions of tumors abutting the FN were used for sensitivity analyses, in a retrospective setting. Propensity score matching was used to assess the impact of FN resection on disease-free survival (DFS), overall survival (OS) and locoregional recurrence-free survival (LRRFS)., Results: A total of 163 patients with parotid cancer abutting or invading the FN without pretreatment facial palsy were included. Among them, 99 patients (61 %) underwent FN resection. After overlap weighting and multiple imputation, no benefit of FN resection over preservation was found in terms of OS (HR = 1.21, p = 0.6), DFS (HR = 0.88, p = 0.5) and LRRFS (HR = 0.99, p = 1). Sensitivity analyses revealed similar results, and no significant efficacy was found in the subgroup analyses., Conclusion: In this retrospective study with propensity score analysis, FN resection did not improve survival outcomes in patients without preoperative facial palsy treated surgically for a primary parotid cancer abutting the FN. In line with recent guidelines, the results of this study suggest that FN preservation should be considered whenever possible in this specific group of patients., Competing Interests: Declaration of competing interest The authors have declared no conflict of interest., (Copyright © 2024 The Authors.

Heart failure (HF) affects six million people in the U.S., is associated with high morbidity, mortality, and healthcare utilization. (1, 2) Despite a decade of innovation, the majority of interventions aimed at reducing hospitalization and readmissions in HF have not been successful. (3-7) One reason may be that most have overlooked the role of home health aides and attendants (HHAs), who are often highly involved in HF care. (8-13) Despite their contributions, studies have found that HHAs lack specific HF training and have difficulty reaching their nursing supervisors when they need urgent help with their patients. Here we describe the protocol for a pilot randomized control trial (pRCT) assessing a novel stakeholder-engaged intervention that provides HHAs with a) HF training (enhanced usual care arm) and b) HF training plus a mobile health application that allows them to chat with a nurse in real-time (intervention arm). In collaboration with the VNS Health of New York, NY, we will conduct a single-site parallel arm pRCT with 104 participants (HHAs) to evaluate the feasibility, acceptability, and effectiveness (primary outcomes: HF knowledge; HF caregiving self-efficacy) of the intervention among HHAs caring for HF patients. We hypothesize that educating and better integrating HHAs into the care team can improve their ability to provide support for patients and outcomes for HF patients as well (exploratory outcomes include hospitalization, emergency department visits, and readmission). This study offers a novel and potentially scalable way to leverage the HHA workforce and improve the outcomes of the patients for whom they care.

Background: Rare cancers constitute less than 10% of head and neck cancers and lack sufficient evidence for standardized care. The French Rare Head and Neck Cancer Expert Network (REFCOR) as established a national database to collect data on these rare cancers. This study aims to describe patient and tumour characteristics in this database., Methods: Prospective data collection was conducted across multiple centers. Survival analyses were performed using Kaplan Meier method and Log Rank test. Odds ratios were used for comparing proportions., Results: A total of 7208 patients were included over a period of 10 years. The most frequent histologies were: Not Otherwise Specified (NOS) adenocarcinoma 13 %, adenoid cystic carcinoma 12 %, squamous cell carcinoma of rare locations 10 %, mucoepidermoid carcinoma 9 %, intestinal-type adenocarcinoma (8 %). Tumours were located in sinonasal area (38 %); salivary glands (32 %); oral cavity / oropharynx / nasopharynx (16 %); larynx / hypopharynx (3 %); ears (1 %); others (3 %). Tumours were predominantly classified as T4 (23 %), N0 (54 %), and M0 (62 %). Primary treatment approach involved tumour resection (78 %) and / or radiotherapy (63 %). Patients with salivary gland cancers exhibited better 5-year overall survival (OS) rates (p < 0.05), and lower recurrence rates compared to patients with sinonasal, laryngeal/ hypopharyngeal cancers. No significant differences were observed in the other comparisons. Acinar cell carcinoma demonstrated the best OS while mucous melanoma had the poorest prognosis., Conclusion: Melanoma, carcinoma NOS, and sinonasal undifferenciated carcinoma still have poor prognoses. Efforts are being made, including training and guidelines, to expand network coverage (REFCOR, EURACAN), improve data collection and contribute to personalized therapies., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Author(s).

Introduction: Laryngeal chondrosarcoma (LCS) is a rare tumor of slow evolution whose treatment is poorly codified. For a long time, a radical treatment by total laryngectomy (TL) was proposed. More recent studies tend to propose a conservative surgical approach of the larynx. The objective of this study was to compare the overall survival (OS) of total laryngectomized patients (TL+) versus non-laryngectomized patients (TL-). The secondary objectives were to analyse the reoperation free survival (RFS), the total laryngectomy free survival (TLFS) and to identify the preoperative factors leading surgeons to propose TL., Materials and Methods: A retrospective analysis of prospectively collected incident cases from the REFCOR and NetSarc-ResOs multicenter databases between March 1997 and June 2021 was conducted. A propensity score matching analysis was performed to compare the OS of TL+ and TL-patients., Results: 74 patients were included. After propensity score, the 5-year OS of TL+ and TL-patients was comparable (100 %, p = 1). The 5-year RFS rate was 69.2 % (95 % CI [57.5-83.4]) and the 5-year TLFS was 61.7 % (95 % CI [50.4-75.5]). Cricoid involvement greater than 50 % (HR 3.58; IC 95 % [1.61-7.92] p < 0.001), an ASA score of 3 or 4 (HR 5.07; IC 95 % [1.64-15.67] p = 0.009) and involvement of several cartilages (HR 5.26; IC 95 % [1.17-23.6] p = 0.04) are prognostic factors for TL. Dyspnea caused by the tumour is a prognostic factor for reoperation (HR 2.59; IC 95 % [1.04-6.45] p = 0.03)., Conclusion: These results demonstrate that conservative treatment should be considered as first-line treatment for laryngeal chondrosarcoma., Competing Interests: Declaration of competing interest None., (© 2023 Published by Elsevier Ltd.)

Objectives: Sinonasal undifferentiated carcinoma (SNUC) is a rare and aggressive disease requiring multimodal treatment, and multiple new entities once included in the spectrum of SNUC, such as SWI/SNF-deficient carcinomas, are emerging. We aimed to provide new data regarding the role of chemotherapy and surgery and the prognostic factors of disease-free survival., Methods: This study was based on data from the REFCOR database and included patients with SNUC treated with curative intent from 2007 to 2021 across 22 centres in France., Results: A total of 80 patients were included in the analysis. Among the entire cohort, the 5-year disease-free survival (DFS) and overall survival (OS) rates were 58% and 63%, respectively. Of 100% of the patients treated with irradiation, 29% underwent surgery, 56% neoadjuvant chemotherapy (82% had either a partial or a complete response) and 76% chemoradiotherapy. No treatment modality was associated with a better OS or DFS, including surgery (p = 0.34). There was a trend for a better DFS for the patients treated with chemotherapy (neoadjuvant or concomitant, p = 0.062). Overall survival at 3 years was 58% for SWI/SNF deficient group and 86% for non deficient group (p = 0.14). The locoregional relapse rate without distant metastases was 21% in the exclusive radiotherapy group and 26% in the surgery group. Grade 3 or higher toxicities concerned 9%, 32% and 29% of patients for surgery, radiotherapy and chemotherapy respectively., Conclusion: In the management of localised SNUC among all patients treated with irradiation, surgery yielded no benefit, whereas the addition of chemotherapy tended to improve disease-free survival., Competing Interests: Declaration of competing interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests:Amaury Daste: Consulting or Advisory Role: Merck, MSD, BMS; Travel, Accommodations, Expenses: BMS, Merck., (© 2023 Published by Elsevier Ltd.)

Objective: to compare the rate of occult contralateral neck metastases (OCNM) in oral and oropharyngeal squamous cell carcinomas (SCC) reaching or crossing the midline and to identify risk factors for OCNM., Materials and Methods: we conducted a single-center retrospective study of oral and oropharyngeal SCC with contralateral cN0 neck. The cohort was divided into a midline-reaching (MR; approaching the midline from up to 10 mm) group and a midline-crossing (MC; exceeding the midline by up to 10 mm) group. Clinical N-status was assessed by a radiologist specializing in head and neck imaging. All patients underwent contralateral elective neck dissection (END)., Results: A total of 98 patients were included in this study, 59 in the MR group and 39 in the MC group. OCNM were present in 17.3% of patients, 20.3% in the MR group and 12.8% in the MC group (p = 0.336). In multivariable analysis, MR/MC status as well as distance from the midline (in mm) were not identified as risk factors for OCNM. Conversely, oropharyngeal primary and clinical N-status above N1 were significantly associated with a higher risk of OCNM, with odds ratios (OR) of 3.98 (95% CI = 1.08-14.60; p = 0.037) and 3.41 (95% CI = 1.07-10.85; p = 0.038) respectively., Conclusion: in patients with oral and oropharyngeal SCC extending close to or beyond the midline, tumor origin and clinical N-status should carry the most weight when dictating the indications for contralateral END, rather than the midline involvement in itself., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 Elsevier Ltd, BASO ~ The Association for Cancer Surgery, and the European Society of Surgical Oncology.

Among the 16,000 new cases of malignant tumors of the head and neck diagnosed in France each year, 10% are not conventional squamous cell carcinomas. These so-called rare cancers are distinguished by their presentation and patterns of failure, which is important to recognize in order to offer specific adapted management and maximize the chances of tumor control. These cancers can be rare by their histology, which determines their local invasiveness, and their hematogenous/nodal spread. Their diagnosis can be difficult and often requires comprehensive immunohistochemistry and genomic techniques. Expert pathology review is recommended in the cases of undifferentiated tumors, sarcomas and at the slightest diagnostic doubt. These rare cancers can also be rare by their anatomical location when arising from the paranasal sinuses, salivary glands and ear. Their location requires knowledge of their specific extension routes, and may call for a specific surgical technique (skull base endoscopic sinus surgery, extended total parotidectomy, etc.) and adapted radiotherapy to spare healthy organs surrounding the tumor. This article (part 1) discusses the diagnostic and therapeutic specificities of these rare cancers, and develops the recommendations of the French ENT Cancer Expertise Network (REFCOR) concerning rare epithelial tumors, i.e., salivary tumors, sinonasal tumors, variants of conventional squamous cell carcinomas, neuroendocrine carcinomas, malignant odontogenic tumors, and ear tumors. A second article (part 2) is focused on non-epithelial tumors (sarcomas, mucosal melanomas, lymphomas, tumors of uncertain or undetermined malignancy) and describes the organization and missions of the REFCOR., (Copyright © 2023 Société Française du Cancer.

Among the 16,000 new cases of malignant tumors of the head and neck diagnosed in France each year, 10% are not conventional squamous cell carcinomas. These so-called rare cancers are distinguished by their presentation and patterns of failure, which is important to recognize in order to offer specific adapted management and maximize the chances of tumor control. These cancers can be rare by their histology as well as their anatomical location when arising from the paranasal sinuses, salivary glands and ear. The management of these heterogeneous rare diseases of complex treatment has considerably been structured over the last 15 years, in particular via the French ENT Cancer Expertise Network (REFCOR) and international networks and registries (EURACAN, etc.). Structuration also favors research with identification of new entities and setting up of specific therapeutic trials.

Purpose: The objective was to assess the local oncological outcomes of endoscopic versus external surgical treatment of sinonasal intestinal-type adenocarcinomas (ITAC) and the factors of recurrence., Methods: a retrospective non-randomized case-control multicenter study was carried out, including 452 untreated sinonasal ITACs recruited from 10 tertiary referral centers. The tumors were re-classified according to the UICC 2017 (pT). Survival curves were obtained using the Kaplan-Meier method. Univariate analysis was done with the log-rank test. Multivariate analysis was performed with a Cox model adjusted for age, T stage, and radiotherapy. A binary logistic regression compared surgical complications and performed two supplementary analyses on positive margins., Results: We compared 195 and 257 patients operated by the external and endoscopic approach, respectively. The mean follow-up was 59.2 ± 48.7 months. Post-operative margins were invaded in 30.6 versus 18.9% of patients, respectively (p = 0.007). The overall recurrence rate was 33.8 versus 24.6%, respectively (p = 0.034). There was a significant difference in favor of the endoscopic approach regarding local recurrence-free survival thanks to better surgical margins in univariate and multivariate analysis (Odd Ratio = 2.01 (1.2-3.36) p = 0.0087). The complication rate (Odds Ratio = 3.4 (1.79-6.32) p < 0.001) was significantly lower in the endoscopic group. The histological positivity of signet-ring cells shows a statistically significant difference in recurrence-free survival (p = 0.0028)., Conclusion: the oncological control of ITAC is better through the endoscopic approach, with negative margins and the absence of signet-ring-cells, two independent factors of recurrence., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2022 Elsevier Ltd, BASO ~ The Association for Cancer Surgery, and the European Society of Surgical Oncology.

Objectives: To identify the factors related to the presence of occult metastases before salvage total laryngectomy (STL) in rcN0 patients and to propose an algorithm to identify patients who do not require neck dissection (ND)., Patients and Methods: This multicentric retrospective study included five centers with recruitment from 2008 to 2018. Inclusion criteria were: i) having been treated for laryngeal squamous cell carcinoma in first intention by radiotherapy (either alone or potentiated or preceded by induction chemotherapy), ii) having received STL with or without ND, iii) having an rcN0 neck at the time of STL., Results: 120 patients met the inclusion criteria. The overall rate of occult metastases was 9.1 %. The rate was significantly higher in patients with an initial positive cN+ lymph node status (p < 0.005) and in advanced stages with rcT3-T4 lesions at recurrence (p < 0.005). Patients with occult metastases recurred earlier than those without (p = 0.002). The overall survival of patients was the same with or without ND (p = 0.16). There were significantly more healing complications requiring revision surgery in the group with ND than in the group without (p = 0.048)., Conclusion: ND does not confer a net survival benefit and is associated with significant complications. Patients without initial lymph node metastases who are rcT1-T2 at recurrence or rcT3-T4 with a recurrence period of more than 12 months could benefit from STL without ND. This decisional algorithm, which needs to be validated, would help avoid 58 % of ND procedures and their proven morbidity., Discipline: Head and neck surgery., (Copyright © 2022 Elsevier Ltd.

Objectives: The objective of this review was to determine the rate and risk factors of paratracheal lymph node (PTLN) involvement during total laryngectomy (TL) or total pharyngolaryngectomy (TPL). In addition, we aimed to assess its prognostic significance in terms of survival and peristomal recurrence., Methods: A comprehensive electronic search was performed on PubMed, EMBASE, and CENTRAL databases. We searched for studies reporting outcomes of PTLN dissection during radical laryngeal surgery for squamous cell carcinoma of the larynx, hypopharynx or cervical oesophagus., Results: We included a total of ten studies (838 patients). The overall rate of PTLN dissection positivity was 18.6% (20.7% for primary TL, 8.7% for salvage TL). Random-effects meta-analysis identified T4 stage, N+ stage of the lateral neck, subglottis involvement and primary tumour arising from the hypopharynx or cervical oesophagus as significant risk factors for PTLN involvement., Conclusions: This meta-analysis allowed to better define the risk of PTLN involvement during TL or TPL, in a bid to guide indication for PTLN dissection. There is a need for further large studies reporting rigorously the outcomes of PTLN dissection in order to establish stronger evidence-based recommendations., (Copyright © 2022.

Background: Salvage total glossectomy (TG) or total glosso-laryngectomy (TGL) remain controversial, as highly morbid procedures. The objective was to describe oncological and functional outcomes after salvage TG or TGL., Methods: We performed a multicenter retrospective study, including patients with previous neck irradiation undergoing TG or TGL for squamous cell carcinoma involving the base of tongue., Results: We included 42 patients: 27 in the TG group and 15 in the TGL group. For the entire cohort, median OS and DFS were estimated at 19 months (95% IC [14-44]) and 10 months (95% IC [7-13]) respectively, with no difference between the two groups. After a median follow-up of 90 months, 10 patients (24%) were alive and free of disease. Att he end of follow-up, we noted a gastrostomy dependency of 89% and 87 %respectively in the TG and TGL group, and 48% of patients in the TG group had a tracheotomy., Conclusion: Although local control is difficult to achieve after salvage TG or TGL, these procedures are associated with acceptable survival and chance of cure for a last-resort situation. TG and TGL can be proposed in selected motivated patients after careful shared decision-making., (Copyright © 2022 Elsevier Ltd. All rights reserved.)

Objectives: The aim of this study was to identify the socio-professional and behavioral factors influencing decision-making between surgical and non-surgical treatment in Upper AeroDigestive Tract (UADT) oncology among surgeons and oncologists., Materials and Methods: We conducted a nationwide online survey among surgeons and medical or radiation oncologists treating head and neck cancer patients in France. The questionnaire collected physicians' demographics, type of practice, individual behavioral characteristics (attitudes toward risk and uncertainty) and data on decision-making via clinical case scenarios., Results: In total, 197 questionnaires were usable. Clinical case scenarios were grouped into three categories according to the prognostic and functional impact of the choice between surgical or non-surgical treatment. For clinical case scenarios where evidence-based medicine considered surgery as the best option, surgeons were significantly more likely to offer surgery in multivariable analysis. When surgery and non-surgical treatment were equivalent, multivariable analysis showed that the tendency to offer surgery increased with the physician's age, and decreased as the number of patients treated per year increased. When non-surgical treatment was the best option because of very high surgical morbidity, multivariable analysis showed a higher propensity to opt for surgery for the age group 40 - 59 versus 25 - 39, and a lower likelihood of choosing surgery among oncologists., Conclusion: This study sheds light on the physicians' socio-professional and behavioral factors influencing decision-making in UADT oncology. These mechanisms, poorly studied and probably underestimated, partly explain the variability of the decisions taken when confronted with clinical situations that are subject to debate., Clinicaltrials: gov ID: NCT03663985., (Copyright © 2022 Elsevier Ltd.

Primary tumours of the salivary glands account for about 5 to 10% of tumours of the head and neck. These tumours represent a multitude of situations and histologies, where surgery is the mainstay of treatment and radiotherapy is frequently needed for malignant tumours (in case of stage T3-T4, nodal involvement, extraparotid invasion, positive or close resection margins, histological high-grade tumour, lymphovascular or perineural invasion, bone involvement postoperatively, or unresectable tumours). The diagnosis relies on anatomic and functional MRI and ultrasound-guided fine-needle aspiration for the diagnostic of benign or malignant tumors. In addition to patient characteristics, the determination of primary and nodal target volumes depends on tumor extensions and stage, histology and grade. Therefore, radiotherapy of salivary gland tumors requires a certain degree of personalization, which has been codified in the recommendations of the French multidisciplinary network of expertise for rare ENT cancers (Refcor) and may justify a specialised multidisciplinary discussion. Although radiotherapy is usually recommended for malignant tumours only, recurrent pleomorphic adenomas may sometimes require radiotherapy based on multidisciplinary discussion. An update of indications and recommendations for radiotherapy for salivary gland tumours in terms of techniques, doses, target volumes and dose constraints to organs at risk of the French society for radiotherapy and oncology (SFRO) was reported in this article., (Copyright © 2021 Société française de radiothérapie oncologique (SFRO).

We present the update of the recommendations of the French society of radiotherapy and oncology on the indications and the technical methods of carrying out radiotherapy of sinonasal cancers. Sinonasal cancers (nasal fossae and sinus) account for 3 to 5% of all cancers of the head and neck. They include carcinomas, mucosal melanomas, sarcomas and lymphomas. The management of sinonasal cancers is multidisciplinary but less standardized than that of squamous cell carcinomas of the upper aerodigestive tract. As such, patients with sinonasal tumors can benefit from the expertise of the French expertise network for rare ENT cancers (Refcor). Knowledge of sinonasal tumour characteristics (histology, grade, risk of lymph node involvement, molecular characterization, type of surgery) is critical to the determination of target volumes. An update of multidisciplinary indications and recommendations for radiotherapy in terms of techniques, target volumes and radiotherapy fractionation of the French society of radiotherapy and oncology (SFRO) was reported in this manuscript., (Copyright © 2021 Société française de radiothérapie oncologique (SFRO).

Introduction: Patients with oropharyngeal squamous cell carcinoma (OPSCC) display a significant risk to develop a metachronous second primary neoplasia (MSPN). HPV and non-HPV-related OPSCC are 2 distinct entities with biological, clinical and prognostic differences. The aims of our study were to analyze the impact of tumor HPV status and other relevant clinical factors, such as tobacco and/or alcohol (T/A) consumption, on the risk and distribution of MSPN in OPSCC patients and to assess the impact of MSPN on patient survival., Material and Methods: All OPSCC patients treated from 2009 to 2014 were included in this multicentric retrospective study. P16 immunohistochemical expression was used as a surrogate maker of tumor HPV status. The impact of tumor p16 status on the risk of MSPN was assessed in uni- and multivariate analyses. Overall survival (OS) was determined by Kaplan-Meier analysis., Results: Among the 1291 patients included in this study, 138 (10.7%) displayed a MSPN which was preferentially located in the head and neck area (H&N), lung and esophagus. Multivariate analyses showed that p16- tumor status (p = 0.003), T/A consumption (p = 0.005) and soft palate tumor site (p = 0.009) were significantly associated with a higher risk of MSPN. We found no impact of p16 tumor status on the median time between index OPSCC diagnosis and MSPN development, but a higher proportion of MSPN arising outside the H&N, lung and esophagus was found in p16 + than in p16- patients. MSPN development had an unfavorable impact (p = 0.04) on OS only in the p16 + patient group., Conclusion: P16 tumor status and T/A consumption were the main predictive factors of MSPN in OPSCC patients. This study provides crucial results with a view to tailoring global management and follow-up of OPSCC patients., (Copyright © 2021 Elsevier Ltd. All rights reserved.)

Objective: To investigate whether palatine tonsillectomy in youth influences the risk of oropharyngeal cancers (OPC) by assessing the association between history of tonsillectomy and risk of tonsillar, base of tongue (BOT) cancer, and other head and neck cancers (HNC)., Materials and Methods: RACKAM was a case-case study comparing frequency of tonsillectomy history in individuals diagnosed with HNC from 2013 to 2018 in 15 centers across France. History of tonsillectomy was defined using combined assessment of patients' recollections and surgeons' visualizations of tonsil area. OPC subsite-specific odds ratios (OR) of tonsillectomy were calculated using multinomial logistic regression with non-oropharyngeal HNC as reference., Results: 1045 patients were included in the study. Frequency of tonsillectomy was 19.5% in patients with tonsillar cancer (N = 85), 49.3% in BOT (N = 76), 33.8% in other oropharyngeal cancers (N = 202) and 38.0% in non-oropharyngeal HNC (N = 682). History of tonsillectomy was inversely associated with tonsillar cancer (adjusted OR 0.4; 95% CI 0.2-0.8), and positively associated with BOT cancer (adjusted OR 1.8; 95% CI 1.1-3.1), but was not associated with all OPC combined (adjusted OR 1.1; 95% CI 0.8-1.4). Sensitivity analyses considering only patients' or surgeons' assessments of tonsillectomy provided comparable results., Conclusion: We confirm the long-term protective effect of tonsillectomy performed in youth on future risk of tonsillar cancer, and our study is the second to report a concurrent increased risk of BOT cancer. Our data suggest that tonsillectomy in youth shifts the site of the first diagnosed oropharyngeal tumor and has a limited impact on overall risk of OPC., (Copyright © 2021.

Objectives: Choice between surgical or medical treatments in head and neck cancer depends of many patient-related and disease-related factors. We investigated how patients' socioeconomic status and practitioners' specialty could affect medical decision-making., Materials and Methods: We conducted a cross-sectional online, nationwide survey, send to surgeons, oncologists and radiotherapists specialized in head and neck oncology. We collected data on medical decision-making for seven clinical scientific scenarios involving head and neck carcinoma and physicians' demographic data. Patients' gender and socioeconomic position were distributed across scientific scenarios using a Latin square design. The scientific scenarios were grouped into several categories according to the prognostic and functional impact of the therapeutic choice., Results: We obtained 206 assessable answers. Surgeons seemed to propose surgery in 49% of cases, whereas oncologists and radiotherapists opted for it in 34% of cases only. This was particularly relevant when the oncological result of surgery and the medical approach were equivalent, and when the surgery appeared to be superior in terms of curative potential but was burdened by a large functional impact. Patient's socioeconomic position also influence therapeutic decision. Among surgeons, the "single male manager" had significantly more chance of being offered surgery than the "married male blue-collar worker". Among oncologists and radiotherapists, the "single male blue-collar worker" had the lowest probability of being proposed surgery. Regarding gender, surgeons tended to offer surgical management more to women regardless of their clinical profile., Conclusions: Patients' sex, marital status, socioeconomic status, practitioners' specialty affect therapeutic management decisions in head and neck oncology., (Copyright © 2021 Elsevier Ltd.

Background: The aim of this study was to assess the impact of the initial therapeutic strategy on oncologic outcomes in patients with HPV-positive OPSCC., Methods: All p16-positive OPSCCs treated from 2009 to 2014 in 7 centers were retrospectively included and classified according to the therapeutic strategy: surgical strategy (surgery ± adjuvant radiotherapy and chemotherapy) vs. non-surgical strategy (definitive radiotherapy ± chemotherapy). Univariate, multivariate propensity score matching analyses were performed to compare overall (OS), disease-specific (DSS) and recurrence-free survival (RFS)., Results: 382 patients were included (surgical group: 144; non-surgical group: 238). Five-year OS, DSS and RFS were 89.2, 96.8 and 83.9% in the surgical group and 84.2, 87.1 and 70.4% in the non-surgical group, respectively. These differences were statistically significant for DSS and RFS after multivariate analysis, but only for RFS after propensity score matching analysis., Conclusion: In p16+ OPSCC patients, upfront surgery results in higher RFS than definitive radiotherapy ± chemotherapy but does not impact OS., (Copyright © 2020 Elsevier Ltd, BASO ~ The Association for Cancer Surgery, and the European Society of Surgical Oncology.

Background: To describe the characteristics of the largest European study of MEC of salivary glands and to determine the prognostic factors for overall and disease free survival., Patients and Methods: Patients with MEC were prospectively included in the Réseau d'Expertise Français sur les Cancers ORL Rares (REFCOR, French Network of Rare Head and Neck Tumors) database between 2009 and 2015., Results: A total of 292 patients were included. Tumors were classified as low grade in 175 cases (60%), intermediate in 39 (13%) and high grade in 78 (27%). Median follow-up was 26 months. The 5-year OS and DFS rates were respectively 83% and 69%. In multivariate analysis, age (p = 0.004), diabetes (p = 0.02) and advanced stage (p = 0.03) were found to have a significant negative impact on OS. Diabetes (p = 0.001), alcohol consumption (p = 0.003) and advanced stage (p = 0.001) were found to have a significant negative impact on DFS. Compare to low grade, high grade tended to have a negative impact on OS (p = 0.05) and had a significant effect on DFS (0.002) while intermediate grade had no significant influence on survival. The surgical treatment had a positive impact on both OS (p = 0.00005) and DFS (p = 0.0005). Postoperative radiotherapy had no impact in multivariate analysis., Conclusion: Advanced clinical stage, high grade tumor, high age, the impossibility of carrying out a complete surgical resection, and diabetes are the main prognostic factors in this prospective series of patients with MEC. Such findings open new research perspectives on the influence of these components on initial patient care., Competing Interests: Declaration of competing interest The authors have no conflicts of interest to disclose., (Copyright © 2020 Elsevier Ltd, BASO ~ The Association for Cancer Surgery, and the European Society of Surgical Oncology.

Introduction: Therapeutic management of oropharyngeal squamous cell carcinomas (OPSCC) is still debated. Since the role of HPV was demonstrated, few studies have focused on HPV-negative OPSCC. The aim of our study was to assess the impact of therapeutic strategy (surgical vs. non-surgical) on oncologic outcomes in patients with HPV-negative OPSCC., Material and Method: All p16-negative OPSCCs treated from 2009 to 2014 in 7 tertiary-care centers were included in this retrospective study and were classified according to the therapeutic strategy: surgical strategy (surgery ± adjuvant radiotherapy and chemotherapy) vs. non-surgical strategy (definitive radiotherapy ± chemotherapy). Patients not eligible for surgery (unresectable tumor, poor general-health status) were excluded. Univariate, multivariate and propensity score matching analyses were performed to compare overall (OS), disease-specific (DSS) and recurrence-free survival (RFS)., Results: Four hundred seventy-four (474) patients were included in the study (surgical group: 196; non-surgical group: 278). Five-year OS, DSS and RFS were 76.5, 81.3 and 61.3%, respectively, in the surgical group and 49.9, 61.8 and 43.4%, respectively, in the non-surgical group. The favorable impact of primary surgical treatment on oncologic outcomes was statistically significant after multivariate analysis. This effect was more marked for locally-advanced than for early-stage tumors. Propensity score matching analysis confirmed the prognostic impact of primary surgical treatment for RFS., Conclusion: Therapeutic strategy is an independent prognostic factor in patients with p16-negative OPSCC and primary surgical treatment is associated with improved OS, DSS and RFS. These results suggest that surgical strategy is a reliable option for advanced stage OPSCC., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2020 Elsevier Ltd, BASO ~ The Association for Cancer Surgery, and the European Society of Surgical Oncology.

Introduction: Patients with oropharyngeal squamous cell carcinoma (OPSCC) display a significant risk of synchronous primary neoplasia (SPN) which could impact their management. The aims of this study were to evaluate the risk and distribution of SPN in OPSCC patients according to their HPV (p16) status, the predictive factors of SPN and the impact of SPN on therapeutic strategy and oncologic outcomes., Material and Methods: All OPSCC patients treated from 2009 to 2014 were included in this multicentric retrospective study. Univariate analyses were conducted using Chi-2 and Fisher exact tests. For multivariate analyses, all variables associated with a p ≤ 0.10 in univariate analysis were included in logistic regression models., Results: Among the 1291 patients included in this study, 75 (5.8%) displayed a SPN which was preferentially located in the upper aerodigestive tract, lung and esophagus. Comorbidity level (p = 0.03), alcohol (p = 0.005) and tobacco (p = 0.01) consumptions, and p16 tumor status (p < 0.0001) were significant predictors of SPN. In multivariate analysis, p16+ status was significantly associated with a lower risk of SPN (OR = 0.251, IC95% [0.133;0.474]). Patients with a SPN were more frequently referred for non-curative treatment (p = 0.02). In patients treated with curative intent, there was no impact of SPN on the therapeutic strategy (surgical vs. non-surgical treatment). We observed no overall survival differences between patients with or without SPN., Conclusion: P16 tumor status is the main predictive factor of SPN in OPSCC patients. This study provides crucial results which should help adapt the initial work-up and the global management of OPSCC patients., (Copyright © 2020 Elsevier Ltd. All rights reserved.)

Global health care is experiencing an unprecedented surge in the number of critically ill patients who require mechanical ventilation due to the COVID-19 pandemic. The requirement for relatively long periods of ventilation in those who survive means that many are considered for tracheostomy to free patients from ventilatory support and maximise scarce resources. COVID-19 provides unique challenges for tracheostomy care: health-care workers need to safely undertake tracheostomy procedures and manage patients afterwards, minimising risks of nosocomial transmission and compromises in the quality of care. Conflicting recommendations exist about case selection, the timing and performance of tracheostomy, and the subsequent management of patients. In response, we convened an international working group of individuals with relevant expertise in tracheostomy. We did a literature and internet search for reports of research pertaining to tracheostomy during the COVID-19 pandemic, supplemented by sources comprising statements and guidance on tracheostomy care. By synthesising early experiences from countries that have managed a surge in patient numbers, emerging virological data, and international, multidisciplinary expert opinion, we aim to provide consensus guidelines and recommendations on the conduct and management of tracheostomy during the COVID-19 pandemic., (Copyright © 2020 Elsevier Ltd.

Background: Among patients with T0-2 N3 head and neck squamous cell carcinomas (HNSCC), those undergoing upfront neck dissection have better oncological outcomes. However, there is no consensual definition of disease resectability of N3 nodes, leading to major treatment attrition and interpretation biases between studies. We established a Delphi method-based consensus to define resectability and impact on decision-making for upfront neck dissection in N3 patients., Methods: The Delphi method was designed as recommended by the French Haute Autorite de Sante among head and neck surgeons from university hospitals and cancer centers, using a 24-item questionnaire. Strong and relative agreements were subsequently established, and recommendations were written. The resulting recommendations were assessed by 30 independent surgeons., Results: N3 nodes with intraparenchymal brain invasion, foramen invasion, skull base erosion, nodes requiring bilateral XII th cranial nerve sacrifice, retropharyngeal N3 node or a node above the plan of soft palate are major contraindications to neck dissection. When neck dissection requires unilateral sacrifice of the IX th or X th or XII th cranial nerves or cervical nerve roots, upfront neck dissection may be performed, based on a case-by-case assessment of other patient and tumor estimates., Conclusion: Consensual contraindications to neck dissection in patients with T0-2 N3 HNSCC were defined among French head and neck surgeons as concerns skull base invasion, retropharyngeal nodes and bilateral XII th cranial nerve sacrifice. This consensus should allow more reliable comparisons between surgical and non-surgical strategies in N3 patients., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2020 Elsevier Ltd.

Background: Salvage surgeries are challenging procedures, with an associated poor prognosis. Management of the N0 neck in those situations remains controversial. We aim to compare oncologic outcomes regarding neck management after surgery for N0 pharyngo-laryngeal carcinoma occurring after loco-regional radiotherapy., Methods: We conducted a multicentric retrospective study, including all patients undergoing surgery for persistent, recurrent or new primary N0 carcinoma of the oropharynx, hypopharynx or larynx between 2005 and 2015, following loco-regional radiotherapy., Results: A total of 239 patients were included, concerning respectively 44%, 34% and 22% oropharyngeal, laryngeal and hypopharyngeal tumors operated. A neck dissection was performed in 143 patients (60%), with an occult nodal metastasis rate of 9%. This rate was higher for hypopharyngeal carcinomas (18%, p = 0.16) and tumors with initial nodal involvement (16%, p = 0.05). With a median follow-up of 60 months, the median overall survival (OS) and progression-free survival rates (PFS) were 34 months and 25 months. We identified negative margin excision status, age at the time of surgery (under 60) and delay between RT and surgery over 2 years as the only variables associated with better OS (p < 0.0001 and p = 0.004) and PFS (p < 0.0001 and p = 0.010) in multivariable analysis, with no difference regarding neck management. Regional progression (alone or with distant metastasis) was noted in 10 cases: 4 in the neck observation group (4%) versus 6 in the neck dissection group (4%)., Conclusion: Elective lymph node dissection of irradiated neck should not be routinely performed in patients undergoing surgery for persistent, recurrent or new primary pharyngo-laryngeal carcinomas., Competing Interests: Declaration of competing interest None, (Copyright © 2020.

Sinonasal carcinomas account for 3% of ENT cancers. They are subdivided into squamous cell carcinomas (50%), adenocarcinomas [20%, mostly of intestinal type (ITAC)], and more rarely, adenoid cystic carcinomas, olfactory neuroblastomas (=esthesioneuroblastomas), neuroendocrine carcinomas or undifferentiated sinonasal carcinomas (SNUC). The 5-year survival rates are, in descending order, 72% for neuroblastomas, 63% for adenocarcinomas, 50-60% for large-cell neuroendocrine carcinomas, 53% for squamous cell carcinomas, 25-50% for adenoid cystic, 35% for small-cell neuroendocrine carcinomas and 35% for SNUC and newly discovered histologies. Surgery is the main treatment; endoscopic approaches reduce the morbidity with equivalent tumour control. Intensity-modulated radiation therapy (IMRT) is almost systematic. Nodal involvement is rare in ethmoidal adenocarcinomas and adenoid cystic carcinomas; it is intermediate and may justify prophylactic radiotherapy for N0 necks in SNUC, neuroblastoma, squamous cell carcinomas and sinonasal neuroendocrine carcinomas. IMRT or proton therapy is the mainstay of treatment of unresectable disease. Radiotherapy optimization by carbon ion therapy for adenoid cystic carcinomas, or by chemotherapy for all carcinomas with IMRT or proton therapy, is investigated within clinical trials in France. Neoadjuvant chemotherapy is reserved for rapidly progressive disease or histologies with a high metastatic potential such as neuroendocrine carcinomas or SNUC. Given their histologic and molecular specificities and different relapse patterns, an expertise of the REFCOR network, with REFCORpath review, is likely to correct diagnoses, rectify treatments, with an impact on survival., (Copyright © 2020 Société Française du Cancer.

Objectives: To analyze the impact of tumor p16 status and other clinical factors on the therapeutic decision-making process in patients with oropharyngeal squamous cell carcinoma (OPSCC)., Methods: We conducted a multicenter retrospective study (GETTEC collaborative study group) enrolling all OPSCC patients with a determined p16-status considered eligible for surgery between 2009 and 2014. The impact of p16-status and other clinical factors on the therapeutic decision was evaluated in multivariate analysis., Results: A total of 476 patients were enrolled in the study, including 244 cases (51%) of p16-positive OPSCC. Overall, 223 (47%) patients underwent primary surgery, and 184 (83%) of them received postoperative radiotherapy ± chemotherapy. More patients with p16-positive OPSCC tended to undergo non-surgical treatment than did patients with p16-negative OPSCC (p = 0.10). Multivariate analysis showed that 5 factors significantly influenced therapeutic management of the patients: T-stage ≥ 3 (towards a non-surgical strategy; p < 0.001), N-stage ≥ 2a (non-surgical strategy; p = 0.02), tumor involvement of the glosso-tonsillar sulcus (surgical strategy; p = 0.002), tumor extension to the oral cavity (surgical strategy; p < 0.009) and the center of care (p < 0.001). The rate of patients directed towards a surgical strategy varied between 9% and 74% depending on the center., Conclusion: There was a non-significant trend to recommend patients with p16-positive OPSCC for non-surgical treatment. Center of care, tumor stage and tumor anatomical subsite and extensions were the main determinants of the treatment choice., (Copyright © 2018 Elsevier Ltd, BASO ~ The Association for Cancer Surgery, and the European Society of Surgical Oncology.

Background: Pyriform sinus carcinomas (SCC) present specific functional and oncological issues. The recent advent of trans-oral robotic surgery (TORS), as a conservative procedure, has opened up new perspectives., Objectives: To present the oncological and functional outcomes of TORS for pyriform sinus SCC., Materials and Methods: We included, retrospectively, all TORS procedures for pyriform sinus SCC performed between 2009 and 2017 in eight French tertiary referral centers. We excluded lesions involving the pyriform sinus that had developed from the oropharynx, larynx, or other anatomic sub-sites of the hypopharynx., Results: We included 57 TORS procedures. Median hospital stay was 10 days. A preventive tracheotomy was performed in seven cases (12%), and all were successfully decannulated. Oral re-feeding was possible for 93%, after a median of 5 days. The main surgical complications were hemorrhages (three cases), all successfully handled, although 2 patients with heavy comorbidities died from blood loss in the days after. Adjuvant therapy was proposed in 31 cases (54%), including two cases of salvage surgery (total pharyngolaryngectomy). After a median follow-up of 23 months, overall and disease-free survival were, respectively, 84% and 74% at 24 months, and 66% and 50% at 48 months. At the end of follow-up, organ preservation rate was 96%. None of the surviving patients needed a tracheotomy and oral diet was possible for 96%., Conclusion: The functional and oncological outcomes of TORS for pyriform sinus cancer are encouraging, and this procedure can be considered safe for selected early or moderately advanced cases as a conservative treatment., (Copyright © 2018 Elsevier Ltd.

Purpose: Optimal timing of neck dissection remains debated in the conservative management of patients with locoregionally advanced squamous cell carcinoma of the head and neck., Patients and Methods: The files of 63 patients with radiographic evidence of bulky or necrotic nodal metastases treated by up-front neck dissection and definitive radiotherapy between 2000 and 2012 at two institutions were retrospectively reviewed., Results: The primary site was oropharyngeal, hypopharyngeal or laryngeal in 63%, 21% and 13% cases, respectively. Overall, 83% of the tumours were staged pN2b or more. Extracapsular spread was found in 48 cases (77%). After a 48-month median follow-up, the 3-year locoregional control and overall survival were 88% and 68%, respectively. Only one isolated failure occurred in the dissected neck., Conclusion: This combination therapy provides a good locoregional tumour control. It should be considered as an option in laryngeal, hypopharyngeal or oropharyngeal squamous cell carcinomas with bulky or necrotic nodal metastases at presentation., (Copyright © 2015 Société française de radiothérapie oncologique (SFRO).

In patients' management affected by head and neck cancers, surgery takes a major place with radiotherapy and chemotherapy. An updating of the surgical techniques available, and validated indications seems useful to harmonize the head and neck oncological surgery practices and so optimize its safety. A focus on the quality assurance in head and neck surgical oncology is proposed.

Aims: Systematic lymph node dissection in patients with papillary thyroid carcinoma (PTC) remains controversial. The objective of this study was to study the pattern of lymph node spread in patients with PTC clinically node-negative and then to propose a lymph node management strategy., Methods: We retrospectively reviewed the records of patients who had undergone total thyroidectomy and a systematic central neck dissection (CND) and lateral neck dissection. Ninety patients with PTC without lymph nodes metastases (LNM) detected on preoperative palpation and ultrasonographic examination were included., Results: Forty-one patients (45.5%) had LNM. Twenty-eight patients (31%) had a central and a lateral involvement. Thirteen patients (14.5%) had only a central involvement. All the patients without LNM in the central compartment were also free in the lateral compartment. There was no correlation between LNM status and TNM staging. The largest LNM in the central compartment was smaller than or equal to 5mm in 66% of the cases, and that could explain the lack of sensitivity of the preoperative ultrasonographic examination., Conclusion: CND could be considered at preoperative or intraoperative diagnosis of PTC whereas lateral neck dissection should be performed only in patients with preoperative suspected and/or intraoperatively proven LNM. Systematic CND allows an objective evaluation of lymph node status in this central cervical area where the LNM are particularly small and difficult to detect preoperatively., (Copyright (c) 2010 Elsevier Ltd.
