RESUMO
Unicentric Castleman disease (UCD) is a lymphoproliferative disease of unknown cause. Paraneoplastic pemphigus (PNP) is a major complication shown to be associated with a poor prognosis, with particular severity in patients with bronchiolitis obliterans (BO). This study describes the clinical and biological characteristics of UCD-PNP patients in a large Western cohort. A total of 148 patients diagnosed with UCD were identified, including 14 patients with a defined PNP. PNP was significantly associated with myasthenia gravis (MG) and FDC sarcoma during follow-up (FDCS). PNP was also significantly associated with reduced survival. These data, together with a multivariate analysis by principal components, led to the identification of UCD-PNP as a group at risk of MG, FDCS and death. PDGFRB sequencing performed on UCD lesions from six patients found the gain-of-function p.N666S variant in two. Interestingly, both patients had hyaline-vascular UCD subtype, were in the UCD-PNP subgroup and had FDCS. Sera from 25 UCD-PNP patients and 6 PNP patients without UCD were tested for PNP-associated autoantibodies. Sera from UCD-PNP patients had a strong reactivity against the N-terminal domain of recombinant periplakin (rPPL, 82%) and showed reactivity against at least two domains of rPPL. These features were not found in patients with UCD alone or in the PNP group without UCD. These data indicate that UCD-PNP patients belong to a subgroup sharing strong clinical and biological identity that might help to decipher the different dynamics of UCD natural history.

Background: Chronic rhinosinusitis with nasal polyps (CRSwNPs) is associated with otitis media with effusion (OME) in about 25% of cases. The objective of this study was to assess the clinical efficacy of the 4 biologic agents currently available in France for severe asthma (omalizumab, mepolizumab, benralizumab and dupilumab) in 17 patients followed for both asthma and chronic rhinosinusitis with nasal polyps (CRSwNP) and presenting otitis media with effusion (OME) on otoscopy. Methods: It was a multicenter retrospective study performed in 4 academic ENT and respiratory departments in Paris, France, with assessment of the clinical evolution of 17 patients with severe eosinophilic asthma and with chronic refractory OME and CRSwNPs treated by biologic agents. Global evaluation of treatment effectiveness (GETE) on asthma, CRSwNP and OME was classified on a 5-point scale as 1, excellent; 2, good; 3, moderate; 4, poor; or 5, symptoms worsening. Response was defined as an excellent/good score (1 or 2). Results: 17 patients were prescribed a total of 30 biologics. The evolution of OME did not follow that of asthma and CRSwNPs in 15 (88%) and 12 (70%) cases, respectively. Concerning OME, 19/30 (63%) patients were non-responders. Among the 10 patients who successively received ≥ 2 biologic agents, the OME response differed, depending on the considered agent Dupilumab had the highest response rate. Conclusions: Resistant OME, associated with asthma and chronic rhinosinusitis with nasal polyps, can present a disconnected evolution under biologics. CRSwNP-associated OME requires a specific evaluation to define the best treatment.

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.

OBJECTIVES: To analyse prognostic factors and survival outcomes of malignant tumors of the external auditory canal, to investigate the role of regional surgery, and adjuvant radiotherapy in early stages and to investigate the role of surgery in operable T4 stage. SETTING: A retrospective analysis was conducted on all patients prospectively included in the national database of the French Expertize Network for Rare ENT Cancers (REFCOR) from January 2000 to December 2016. PARTICIPANTS: 103 patients from 19 reference centers were included. A propensity score matching analysis was applied to enable comparisons between treatments. MAIN OUTCOMES AND MEASURES: Event-free survival, overall survival and factors of poor prognosis of the cohort were described. The interest of local and regional surgery and postoperative radiotherapy were evaluated. RESULTS: The factors of poor prognosis on event-free survival were immunosuppression (p = 0.002), Karnofsky status less than 90% (p = 0.02), body mass index less than 19 Kg / m2 (p = 0.0009), peripheric facial palsy (p = 0.0016), and positive margin (p = 0.0006). In early stages, locoregional surgery was associated with an increase in event-free survival (p = 0.003, HR = 0.21) versus local surgery alone, while postoperative radiotherapy was not associated with an increase in event-free survival (p = 0.86, HR = 0.91) or overall (p = 0.86, HR = 0.91). In locally advanced stages, locoregional surgery followed by radiotherapy was associated with an increase in event-free survival (p = 0.03, HR = 0.39) and overall (p = 0.02, HR = 0.34) versus chemoradiotherapy alone. CONCLUSION AND RELEVANCE: Regional surgery is recommended for early stages of cancers of the external auditory canal. In operable cases, locoregional surgery followed by radiotherapy is recommended.

OBJECTIVES: The management of upper aerodigestive tract cancers is a complex specialty. It is essential to provide an update to establish optimal care. At the initiative of the INCa and under the auspices of the SFORL, the scientific committee, led by Professor Béatrix Barry, Dr. Gilles Dolivet, and Dr. Dominique De Raucourt, decided to develop a reference framework aimed at defining, in a scientific and consensus-based manner, the general principles of treatment for upper aerodigestive tract cancers applicable to all sub-locations. METHODOLOGY: To develop this framework, a multidisciplinary team of practitioners was formed. A systematic analysis of the literature was conducted to produce recommendations classified by grades, in accordance with the standards of the French National Authority for Health (HAS). RESULTS: The grading of recommendations according to HAS standards has allowed the establishment of a reference for patient care based on several criteria. In this framework, patients benefit from differentiated care based on prognostic factors they present (age, comorbidities, TNM status, HPV status, etc.), conditions of implementation, and quality criteria for indicated surgery (operability, resectability, margin quality, mutilation, salvage surgery), as well as quality criteria for radiotherapy (target volume, implementation time, etc.). The role of medical and postoperative treatments was also evaluated based on specific criteria. Finally, supportive care must be organized from the beginning and throughout the patients' care journey. CONCLUSION: All collected data have led to the development of a comprehensive framework aimed at harmonizing practices nationally, facilitating decision-making in multidisciplinary consultation meetings, promoting equality in practices, and providing a state-of-the-art and reference practices for assessing the quality of care. This new framework is intended to be updated every 5 years to best reflect the latest advances in the field.

BACKGROUND: Acinic cell carcinomas (AciCCs) are malignant tumours of the salivary glands. The aim of this work was to analyse data from the national REFCOR multicenter cohort (i) to investigate the prognostic factors influencing survival outcomes in AciCC, (ii) to assess the impact on survival of postoperative radiotherapy (RT) in patients treated for AciCC without high-grade transformation and (iii) to explore the prognostic impact of prophylactic neck dissection (ND) in patients treated for AciCC of the major salivary glands. PATIENTS AND METHODS: Data from all the patients treated for salivary AciCC between 2009 and 2020 were extracted from the REFCOR database. Survival outcomes and prognostic factors influencing Disease-Free Survival (DFS) and Overall Survival (OS) were investigated using univariate and multivariate analyses. Propensity score matching was used to assess the impact of postoperative RT and prophylactic ND on DFS. RESULTS: A total of 187 patients were included. After a median follow-up of 53 months, their 5-year OS and DFS rates were 92.8% and 76.2%, respectively. In multivariate analysis, male sex, older age, higher T and N status, and high grade were independently associated with a worse DFS. In the subpopulation analysed after propensity score matching, patients with cN0 AciCC without high-grade transformation who were treated by surgery and RT did not have an improved DFS compared to patients who were treated by surgery alone (hazard ratio (HR) = 0.87, p = 0.8). Factors associated with nodal invasion were T3-T4 status and intermediate/high histological grade. After propensity score matching, prophylactic ND was associated with a trend toward a better DFS (HR = 0.46, p = 0.16). CONCLUSIONS: These results suggest that (i) long-term follow-up (>5 years) should be considered in patients with AciCC, (ii) treatment by surgery alone could be an option in selected cN0 patients with AciCC without high-grade transformation and (iii) prophylactic ND may be considered preferentially in patients with T3-T4 status and/or intermediate/high histological grade.

Mammalian target of rapamycin (mTOR) regulates cellular functions by integrating intracellular signals and signals from the tumor microenvironment (TME). The PI3K-AKT-mTOR pathway is activated in 70% of head and neck squamous cell carcinoma (HNSCC) and associated with poor prognosis. This phase I-II study investigated the effect of mTOR inhibition using weekly everolimus (30 mg for dose level 1, 50 mg for dose level 2) combined with weekly induction chemotherapy (AUC2 carboplatin and 60 mg/m2 paclitaxel) in treatment-naïve patients with locally advanced T3-4/N0-3 HNSCC. Patients received 9 weekly cycles before chemoradiotherapy. Objectives were safety and antitumor activity along with tissue and blood molecular biomarkers. A total of 50 patients were enrolled. Among 41 evaluable patients treated at the recommended dose of 50 mg everolimus weekly, tolerance was good and overall response rate was 75.6%, including 20 major responses (≥50% reduction in tumor size). A significant decrease in expression of p-S6K (p-value: 0.007) and Ki67 (p-value: 0.01) was observed in post-treatment tumor tissue. Pro-immunogenic cytokine release (Th1 cytokines IFN-γ, IL-2, and TNF-ß) was observed in the peripheral blood. The combination of everolimus and chemotherapy in HNSCC was safe and achieved major tumor responses. This strategy favorably impacts the TME and might be combined with immunotherapeutic agents.
RESUMO
INTRODUCTION: The most common malignancies metastasizing to the heart are cancers of the lung, breast, mesothelioma, melanoma, leukemia, and lymphoma. Cardiac metastasis from a tongue cancer is a rare finding and only a few cases have been reported previously in the literature. In this case report and literature review, we discuss the main clinical features of patients with cardiac metastases secondary to a tongue cancer and imaging modalities performed, especially the 18F-Fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT). PATIENT CONCERNS: This is a case of a 39-year-old woman who in April 2018 was diagnosed with an invasive well differentiated squamous cell carcinoma of the movable tongue. She underwent a left hemiglossectomy followed by a revision of hemiglossectomy and ipsilateral selective neck lymph nodes dissection levels II to III because of pathological margins. An early inoperable clinical recurrence was diagnosed and she received radiochemotherapy with good clinical and metabolic response. She remained asymptomatic thereafter. DIAGNOSIS: In January 2020, a pre-scheduled 18F-FDG PET/CT showed a diffuse cardiac involvement. In February 2020, a biopsy of the lesion revealed a metastatic squamous cell carcinoma. INTERVENTIONS: She was deemed to not be a cardiac surgical candidate and treated by palliative chemotherapy: taxol-carboplatin associated with cetuximab then cetuximab alone because of adverse effects. A re-evaluation imaging performed in April 2020 evidenced a progression of the cardiac involvement, which led to switch chemotherapy by immunotherapy with nivolumab. OUTCOMES: This patient had a very poor prognosis and succumbed to major heart failure 4 months after the diagnosis of cardiac metastasis. CONCLUSION: In this case report, 18F-FDG PET/CT proved to be useful in detecting cardiac metastasis and changed the therapeutic management of the patient. It suggests that patients with tongue malignancies in a context of poor initial prognosis should be followed-up early by 18F-FDG PET/CT with HFLC diet to facilitate detection of recurrence.

BACKGROUND: Tracheostomy has been proposed as an option to help organize the healthcare system to face the unprecedented number of patients hospitalized for a COVID-19-related acute respiratory distress syndrome (ARDS) in intensive care units (ICU). It is, however, considered a particularly high-risk procedure for contamination. This paper aims to provide our experience in performing tracheostomies on COVID-19 critically ill patients during the pandemic and its long-term local complications. METHODS: We performed a retrospective analysis of prospectively collected data of patients tracheostomized for a COVID-19-related ARDS in two university hospitals in the Paris region between January 27th (date of first COVID-19 admission) and May 18th, 2020 (date of last tracheostomy performed). We focused on tracheostomy technique (percutaneous versus surgical), timing (early versus late) and late complications. RESULTS: Forty-eight tracheostomies were performed with an equal division between surgical and percutaneous techniques. There was no difference in patients' characteristics between surgical and percutaneous groups. Tracheostomy was performed after a median of 17 [12-22] days of mechanical ventilation (MV), with 10 patients in the "early" group (≤ day 10) and 38 patients in the "late" group (> day 10). Survivors required MV for a median of 32 [22-41] days and were ultimately decannulated with a median of 21 [15-34] days spent on cannula. Patients in the early group had shorter ICU and hospital stays (respectively 15 [12-19] versus 35 [25-47] days; p = 0.002, and 21 [16-28] versus 54 [35-72] days; p = 0.002) and spent less time on MV (respectively 17 [14-20] and 35 [27-43] days; p<0.001). Interestingly, patients in the percutaneous group had shorter hospital and rehabilitation center stays (respectively 44 [34-81] versus 92 [61-118] days; p = 0.012, and 24 [11-38] versus 45 [22-71] days; p = 0.045). Of the 30 (67%) patients examined by a head and neck surgeon, 17 (57%) had complications with unilateral laryngeal palsy (n = 5) being the most prevalent. CONCLUSIONS: Tracheostomy seems to be a safe procedure that could help ICU organization by delegating work to a separate team and favoring patient turnover by allowing faster transfer to step-down units. Following guidelines alone was found sufficient to prevent the risk of aerosolization and contamination of healthcare professionals.

BACKGROUND: Patterns of nodal involvement in adenoid cystic carcinoma (ACC) of the head and neck have not been sufficiently assessed to guide a decision of prophylactic neck dissection (ND). The objective of this study is to analyse the influence of ND on event-free survival (EFS) for patients with cN0 ACC. PATIENTS AND METHODS: A multicentre prospective study was conducted between 2009 and 2018. Patients presenting cN0 non-metastatic ACC on any site, and who received surgery on the tumour, were included. EFS was the main judgement criterion. A comparative survival analysis between the groups that received a ND versus those that did not was performed, using a propensity score. Analyses were carried out using the R software. RESULTS: Between 2009 and 2018, 322 patients with cN0 ACC were included, out of which 58% were female. The average age was 53 years. Tumours were in minor salivary glands in 58% of cases, and 52% had T3/T4 stages. ND was performed on 46% of patients. Out of them, seven had histological lymph node invasion, out of which six had tumour infiltration in the mucosa of oral cavity. After propensity score, the median EFS for N0 patients with ND was 72 months (95% Confidence Interval (CI) [48-81]), compared to 73 months (95% CI [52-85]) for patients without ND (HR = 1.33; 95% CI [0.82-2.16]; p = 0.2). CONCLUSION: ND of cN0 patients does not provide any benefit on EFS, which suggests that its application on such patients is not necessary.

The microenvironment of solid tumors has become a promising target for future therapies modulating immune cells. Patients with advanced head and neck cancer, which still portends a poor outcome, are particularly in need of innovative approaches. In oral squamous cell carcinoma, high density of tumor-associated macrophages (TAMs) appears consistently associated with poor prognosis, whereas data are currently limited for other head and neck sites. Several approaches to block TAMs have been investigated, including TAMs inactivation by means of the colony stimulating factor 1 (CSF-1)/CSF-1 receptor (CSF-1R) inhibitors or strategies to reprogram TAMs from M2 protumoral phenotype toward M1 antitumoral phenotype. This review focuses on both prognostic and therapeutic aspects related to TAMs in head and neck carcinomas.

Otitis media with effusion (OME) is a very common condition in the current clinical practice. Usually idiopathic, it may sometimes be the consequence of primary diseases. Extracranial meningioma is rare, and even more when involving the ear and temporal bone. We report a case of temporal meningioma spreading to the middle ear and mastoid presenting as an OME. The diagnosis relies on a thorough imaging evaluation with computed tomography and magnetic resonance imaging. This short report aims to warn the otolaryngologist of this rare situation to prevent any delay in diagnosing and managing such a condition.

BACKGROUND: Video-assisted thoracic surgery (VATS) is usually performed using three ports. Uniportal VATS has not yet been widely developed. We report our single institution experience in uniportal VATS for the surgical management of 351 patients with pneumothorax. METHODS: Between November 2009 and February 2016, we conducted a study in 351 patients treated for pneumothorax using uniportal VATS. Resection of apical bullae associated with partial pleurectomy, pleural abrasion, or talc effusion was performed. RESULTS: The mean age was 29.6 ± 10.1 years. Surgical indications were mainly persistence or recurrence of pneumothorax. Sixty-seven patients (19%) presented with complications. At the 30-day control, 60.1% of patients were asymptomatic; 85% of patients were satisfied with the single small scar. The recurrence rate was 3.6% at 24 ± 13 months. CONCLUSIONS: Uniportal VATS is feasible, safe, and reproducible in the treatment of pneumothorax. Morbidity is similar to multiport VATS. The recurrence rate is comparable with best results after multiport VATS or thoracotomy. Patients were satisfied with the single small scar.
