Resection and reconstruction of the carotid artery for head and neck squamous cell carcinoma: a GETTEC study.

OBJECTIVES: Main: To describe 1-year overall survival (OS) after primary or salvage management of head and neck squamous cell carcinoma (HNSCC) invading the common or internal carotid artery (CCA/ICA). Secondary: To assess disease control rate, treatment morbidity, and radio-anatomopathologic correlation. METHODS: Retrospective study of 67 patients, treated between 1999 and 2020 for N3bM0 HNSCC invading the CCA/ICA as identified by CT-scan. Tumors that could not have been resected with a complete en-bloc resection sacrificing and reconstructing the CCA/ICA were excluded. Patients were separated into two groups (primary or salvage treatment) and studied according to the type of treatment they received: radiotherapy/radiochemotherapy (RT/RCT), surgery, or systemic therapy (ST). RESULTS: For newly treated patients, the 1-year OS was significantly better after RT/RCT (73%) than after surgery (40%, p < 0.0001). In the salvage setting, the 1-year OS after surgery (40%) was better than after ST (14%, statistically suggestive difference with p = 0.0241). Surgery improved cervical control, but distant metastases occurred in more than 50% of cases regardless of treatment. No neurological complication occurred after carotid reconstruction. Perioperative mortality was 7% (1/15). The carotid invasion was confirmed by pathological examination in all five patients with an arterial deformation on CT-scan, in seven among eight patients with CCA/ICA encasement greater than 270°, and in four out of seven patients with CCA/ICA encasement between 180° and 270°. CONCLUSION: Neck dissection with carotid resection and reconstruction is technically feasible with acceptable neurovascular morbidity. For newly treated patients, survival is better after RT/RCT. For salvage treatment, surgery could be proposed to selected patients.

Airway management during transoral robotic surgery for head and neck cancers: a French GETTEC group survey.

PURPOSE: The aim of the survey was to define the indications for preventive tracheostomy in transoral robotic surgery (TORS) for head and neck cancers. METHODS: From October 2019 to January 2020, an online questionnaire was e-mailed to French surgical ENT teams with considerable experience of the TORS procedure (Gettec group). A descriptive analysis of the answers was performed. RESULTS: Eighteen French surgical teams answered the questionnaire. For 77.8% of the surgical teams, a past history of radiotherapy with residual edema was an indication for prophylactic tracheostomy, and for 88.9%, > 75 mg of antiplatelet medication or anticoagulation treatment was an indication. CONCLUSION: Early preventive tracheostomy during TORS can protect airway from uncommon but potentially life-threatening complications, such as transoral hemorrhage or airway edema. We recommend it in high-risk situations, such as a past history of radiotherapy or antiplatelet therapy associated with large resections. Further studies are needed to establish evidence-based recommendations.

Oral tongue squamous cell carcinomas in young patients according to their smoking status: a GETTEC study.

BACKGROUND: Incidence of oral tongue squamous cell carcinoma (OTSCC) is increasing, especially in young adults, despite decreasing tobacco and alcohol consumption. METHODS: This multicentric retrospective study of 185 young adults with OTSCC (median follow-up 43 months), investigated risk factors, tumour characteristics and oncological outcomes according to the smoking status. RESULTS: Overall, 38% of patients were smokers (S). Non-smokers (NS) were significantly younger than S. Sex ratios were 1.1 for N and 1.8 for S. NS patients were less frequently cannabis or alcohol users than S, but were more likely to have a history of leukoplakia. Second primaries were observed in NS (4.4%) and in S (12.7%). Despite more frequent local relapse in NS (p = 0.018), there was no difference in diagnostic stage and overall survival between groups. CONCLUSION: OTSCC affects differently young S and NS patients suggesting the existence of a specific clinical entity of OTSCC in non-smoking young adults.

Type 2 immunity-driven diseases: Towards a multidisciplinary approach.

Asthma, atopic dermatitis and chronic rhinoconjunctivitis are highly heterogeneous. However, epidemiologic associations exist between phenotypic groups of patients. Atopic march is one such association but is not the only common point. Indeed, beyond such phenotypes, hallmarks of type 2 immunity have been found in these diseases involving immune dysregulation as well as environmental triggers and epithelial dysfunction. From the canonical Th2 cytokines (IL-4, IL-5, IL-13), new cellular and molecular actors arise, from the epithelium's alarmins to new innate immune cells. Their interactions are now better understood across the different environmental barriers, and slight differences appeared. In parallel, the development of type 2-targeting biotherapies not only raised hope to treat those diseases but also raised new questions regarding their true pathophysiological involvement. Here, we review the place of type 2 immunity in the different phenotypes of asthma, chronic rhinitis, chronic rhinosinusitis and atopic dermatitis, highlighting nuances between them. New hypotheses rising from the use of biotherapies will be discussed along with the uncertainties and unmet needs of this field.

Effect of the Use of Intranasal Spray of Essential Oils in Patients with Perennial Allergic Rhinitis: A Prospective Study.

INTRODUCTION: Among allergic rhinitis (AR) symptoms, nasal obstruction particularly affects the quality of life. Antihistamines and intranasal corticosteroids are the most frequently prescribed symptomatic drugs, but their efficacy is often incomplete. Essential oils (EO) have shown an anti-inflammatory effect and potential in treating patients with AR. The aim of this study was to evaluate the effectiveness of a hypertonic EO-based nasal spray on perennial AR (PAR) symptoms. METHODS: This prospective, open-label, non-randomized, multicentric trial included 43 patients with PAR sensitized to mites, not controlled for more than a year. All were treated with Puressentiel® Respiratory-Decongestant Nasal Spray for 30 days. Their usual treatment remained unchanged during the study period. Before and after treatment, each participant filled out a rhinitis questionnaire, the Allergic Rhinitis Control Test (ARCT). A nasal inspiratory peak flow (NIPF) was performed. RESULTS: The mean ARCT was 16.4 and 20.5 at D0 and D30, respectively (p < 0.001); the mean increase between D0 and D30 was 4.1 (p < 0.001). The proportion of patients with controlled rhinitis after 30 days of treatment was 69.8 versus 14% before treatment (p < 0.001). The mean NIPF was 86.5 L/min and 105.1 L/min at D0 and D30, respectively (p < 0.001); the mean increase between D0 and D30 was 18.5 L/min. CONCLUSION: A hypertonic EO-based nasal spray could be a new and natural option in the management of PAR. It could also be used as an add-on therapy when nasal symptoms are not fully controlled.

Good clinical practice recommendations for the use of PET/CT in oncology.

Positron emission tomography/computed tomography (PET/CT) is a nuclear medicine functional imaging technique with proven clinical value in oncology. PET/CT indications are continually evolving with fresh advances made through research. French practice on the use of PET in oncology was framed in recommendations based on Standards-Options-Recommendations methodology and coordinated by the French federation of Comprehensive Cancer Centres (FNLCC). The recommendations were originally issued in 2002 followed by an update in 2003, but since then, a huge number of scientific papers have been published and new tracers have been licenced for market release. The aim of this work is to bring the 2003 version recommendations up to date. For this purpose, a focus group was set up in collaboration with the French Society for Nuclear Medicine (SFMN) to work on developing good clinical practice recommendations. These good clinical practice recommendations have been awarded joint French National Heath Authority (HAS) and French Cancer Institute (INCa) label status-the stamp of methodological approval. The present document is the outcome of comprehensive literature review and rigorous appraisal by a panel of experts, organ specialists, clinical oncologists, surgeons and imaging specialists. These data were also used for the EANM referral guidelines.

Locoregional control, progression-free survival and morbidity rates in N3 head and neck cancer patients with low primary tumour burden: A 301-patient study.

OBJECTIVES: In patients with N3 head and neck squamous cell carcinoma (HNSCC), N3 disease is associated with high regional relapse and metastatic risks. Patients with resectable N3 disease have better prognosis although their metastatic risk may be similar as in patients with unresectable disease. Neoadjuvant chemotherapy has been associated with lower metastatic rates, but N3 patients may die of rapid locoregional progression. We assessed outcomes with the three modalities in patients with low primary burden to better assess the specific prognosis of N3 disease. METHODS: This retrospective multicentric study included T0-2 N3 HNSCC patients. Outcomes and morbidity in upfront neck dissection (uND) vs non-surgical groups were analysed and oncological outcomes and morbidity compared between patients undergoing chemoradiation or neoadjuvant chemotherapy in patients with initially unresectable N3 nodes. RESULTS: Of 301 patients, 142 (47%) underwent uND, 68 (23%) neoadjuvant chemotherapy and 91 (30%) chemoradiation. The 24- and 60-month incidence of locoregional relapse was 23.2% [18.3%; 28.4%] and 27.4% [21.8%; 33.3%]; it was lower in patients undergoing uND (P = .006). In patients with non-surgical treatments, success rates were 57.8% [49.4%; 66.3%] after chemoradiation and 38.1% [29.6%; 46.7%] after neoadjuvant chemotherapy (P = .001). Overall morbidity was more frequent in patients undergoing uND (68.8%) (P < .001). CONCLUSION: uND improved locoregional control but increased morbidity and showed no survival benefit. Success rates were better after chemoradiation versus neoadjuvant chemotherapy. Neoadjuvant chemotherapy did not reduce metastatic rates but non-responders to chemoradiation had poor PFS and survival rate, suggesting that predictive criteria are warranted.

Surgery or Radiotherapy of the Primary Tumor in T1-2 Head and Neck Squamous Cell Carcinoma with Resectable N3 Nodes: A Multicenter GETTEC Study.

BACKGROUND: The prognosis of advanced nodal (N3) squamous cell carcinoma of the head and neck (HNSCC) is poor. We investigated whether surgery or radiotherapy of early (T1-2) primary stage HSNCC is preferable to limit the overall morbidity after upfront neck dissection (uND) for N3 disease. METHODS: This retrospective multicentric Groupe d'Étude des Tumeurs de la Tête Et du Cou study included patients undergoing uND and surgery or radiotherapy of their primary. Prognostic factors were evaluated using propensity score matching to account for biases in performing surgery depending on primary site and stage. RESULTS: Of 189 T1-2, N3 HNSCC patients, 70 (37.0%) underwent uND: 42 with surgery of their primary and 28 with radiotherapy only. Radiotherapy alone was more frequent in patients with hypopharyngeal primaries. All local (N = 3) and regional (N = 10) relapses (included 2 locoregional relapses) occurred within the first 2 years. There were 16 distant metastatic failures. Five-year locoregional relapse and survival incidences were 15.7% and 66.5% and were similar regardless of the treatment of the primary. The overall morbidity rate was 65.2% and was similar after weighting by the inverse propensity score (p = 0.148). The only prognostic factor for morbidity was the radicality of the uND. Prolonged parenteral feeding was not more frequent in patients only irradiated to their primary (p = 0.118). Prolonged tracheostomy was more frequent after surgery of the primary. CONCLUSIONS: In patients with T1-2, N3 HNSCC undergoing uND, radiotherapy and surgery of the primary yield similar oncological outcomes. Morbidity was related to the extent of neck dissection.

Prospective evaluation of oral corticosteroid as a predictor of postoperative olfactory recovery after functional endoscopic surgery for nasal polyposis.

PURPOSE: Anticipating the possibility of olfactory recovery after functional endoscopic surgery (FES) in nasal polyposis (NP) is difficult. The main objective of this study was to assess the predictive factors of recovering the sense of smell after radical bilateral ethmoidectomy. Secondary objectives were to identify other predictors of olfactory recovery. METHODS: Open prospective study was conducted at the Nantes University Hospital including all patients with NP operated on in the Ear, Nose, and Throat Department between January 2011 and September 2017. These patients underwent functional endoscopic surgery (radical ethmoidectomy) after medical treatment failure. Olfaction was quantified prospectively and systematically during the preoperative consultation using a visual analog scale. Multivariate analysis evaluated the presence of predictive factors of postoperative olfactory recovery. RESULTS: One hundred nineteen patients were included in the study. Overall, olfaction was partially improved after surgery. For patients who presented greater than 50% recovery of olfaction after systemic corticosteroid therapy before surgery, we observed a predictive better rate of olfactory recovery after surgery (p < 0.001). Age over 65 years, a history of sinonasal surgery, associated asthma, and bacterial colonization were not associated with less postoperative olfactory recovery. CONCLUSION: This study identified an objective factor that may influence olfactory recovery after FES using a therapeutic trial for olfactory recovery after oral corticosteroid treatment taken before surgery.

Prospective, randomized, controlled, open-label study to compare efficacy of a mineral-rich solution vs normal saline after complete ethmoidectomy.

PURPOSES: The purpose of this study was to compare the efficacy of a mineral-rich solution vs normal saline solution (0.9% NaCl) following endoscopic complete bilateral ethmoidectomy. METHODS: This was a prospective, multicenter, randomized, controlled, open-label trial in subjects suffering from steroid-resistant sinonasal polyposis. Adults performed 4 nasal irrigations of mineral or saline solutions daily for 28 days. Evaluations included subject-reported RHINO quality of life (QoL) and NOSE scores, tolerability, and satisfaction, the Lund-Kennedy endoscopic score and assessments of crusting, secretions and mucociliary clearance (rhinoscintigraphy). RESULTS: A total of 189 subjects were randomized. Clinically relevant improvements (> 20 points) in RhinoQOL and NOSE scores were measured in both groups without any significant inter-group difference. Among the subjects with impaired RhinoQOL at pre-inclusion, the change in Impact-RhinoQOL score was significantly superior in mineral-rich vs saline solution at day 21 (p = 0.028) and day 28 (p = 0.027). The Lund-Kennedy score continuously improved in both groups earlier with the mineral-rich solution. Crusts were significantly fewer in number and less severe/obstructive in patients receiving mineral-rich vs saline solution at day 7 (p = 0.026) and day 14 (p = 0.016). Furthermore, secretions disappeared significantly more quickly and were less thick/purulent with mineral-rich solution at day 14 (p = 0.002) and day 21 (p = 0.043). Less epistaxis was reported in the mineral vs saline solution (p = 0.008 at day 21). CONCLUSIONS: Our findings indicate that the composition of a nasal irrigation solution influences endoscopic scores and QoL after sinus surgery for patients over 60, those with an initially poor QoL and higher symptom score, and smokers.

PCR-based detection of Aspergillus fumigatus and absence of azole resistance due to TR34 /L98H in a french multicenter cohort of 137 patients with fungal rhinosinusitis.

Fungal rhinosinusitis (FRS) has a worldwide distribution, comprises distinct clinical entities but is mostly due to Aspergillus among which Aspergillus fumigatus plays a major role in European countries. Although, there is accumulating evidence for the emergence of environmentally acquired-azole resistance in A. fumigatus (such as TR34 /L98H) in various clinical settings, there is few data for patients with FRS. In this study, we aimed to investigate the prevalence of A. fumigatus azole resistance due to TR34 /L98H in a multicentre cohort of patients with FRS. One hundred and thirty-seven patients with FRS admitted between 2002 and 2016 at four French medical centres were retrospectively enrolled. Clinical and mycological findings were collected. Aspergillus fumigatus and the TR34 /L98H alteration conferring azole resistance were investigated directly from clinical samples using the commercial CE-IVD marked MycoGENIE® A. fumigatus real-time PCR assay. Fungal ball was the more frequent clinical form (n = 118). Despite the presence of fungal hyphae at direct microscopic examination, mycological cultures remained negative for 83 out of the 137 patients (60.6%). The PCR assay proved to be useful allowing the identification of A. fumigatus and etiological diagnosis in 106 patients (77.4%) compared with 44 patients (32.1%) when using culture as the reference method. Importantly, neither TR34 nor L98H alterations were evidenced.

Vascular Supply of the Auricle: Anatomical Study and Applications to External Ear Reconstruction.

BACKGROUND: Reliable reconstructive flaps require convenient vascular supply. Thus, precise description of the vascular patterns of external ear is not completely elucidated. OBJECTIVE: This anatomical study aims to provide comprehensive data of the arterial network of the auricular region, anastomosis, and patterns of arterial dependence regarding external ear subunits. MATERIALS AND METHODS: After dyed latex injections in the external carotid artery, eleven auricles have been carefully dissected to examine the vascular network of the auricular region. RESULTS: In all cases, the posterior auricular artery (PAA) supplied the cranial side of the auricle, as well as the concha on the lateral side through consistent perforating branches. The superficial temporal artery (STA) network supplied the upper third of the lateral aspect of the auricle. The authors' dissections showed a clear dominance of the PAA supply. However, the two arteries consistently developed anastomoses particularly in the cranial upper third of the auricle. CONCLUSION: Consistent branches and anastomoses between the PAA and the STA network provide reliable pedicles for auricular and facial reconstruction.

Cervical spondylodiscitis following an invasive procedure on the neopharynx after circumferential pharyngolaryngectomy: a retrospective case series.

PURPOSE: To highlight cervical spondylodiscitis as an infrequent complication following an invasive procedure on the neopharynx in patients previously treated with circumferential pharyngolaryngectomy with pectoralis major myocutaneous flap reconstruction. METHODS: Patients diagnosed with cervical spondylodiscitis after circumferential pharyngolaryngectomy between 2001 and 2013 were retrospectively studied using a questionnaire sent to the French head and neck tumour study group. Medical history; tumour management; clinical symptoms; biological, microbiological and imaging results; and management of the infection were collected for each patient. RESULTS: Six men aged 51-66 years were diagnosed with spondylodiscitis on average 5.6 years after circumferential pharyngolaryngectomy, and a mean 2 months following an invasive procedure on the neopharynx (oesophageal dilatation, phonatory prosthesis insertion). The patients presented with cervical pain and increased CRP level. MRI showed epidural abscess and communication between the pharynx and vertebral bodies in most cases. Microbiological samples yielded bacteria from the pharynx flora. Infection was managed using antibiotics adjusted according to the culture results and spinal immobilisation for duration of 6-12 weeks. No surgical treatment was required. During follow-up, no patient experienced recurrence or residual disability. CONCLUSIONS: Cervical spondylodiscitis is a rare but potentially severe complication following an invasive procedure on the neopharynx after circumferential pharyngolaryngectomy. Therefore, the onset of nonspecific symptoms should not be overlooked, and MRI must be performed if infection is suspected. Microbiological confirmation is critical in optimising treatment, which should be aggressive, even if overall prognosis seems to be good.

Micro-CT Analysis of Radiation-Induced Osteopenia and Bone Hypovascularization in Rat.

Treatment of carcinomas of the upper aerodigestive tract often requires external radiation therapy. However, radiation affects all the components of bone, with different degrees of sensitivity, and may produce severe side effects such as mandibular osteoradionecrosis (ORN). Intraosseous vascularization is thought to be decreased after irradiation, but its impact on total bone volume is still controversial. The aim of this study was to compare intraosseous vascularization, cortical bone thickness, and total bone volume in a rat model of ORN versus nonirradiated rats, using a micro-computed tomography (micro-CT) analysis after intracardiac injection of a contrast agent. The study was performed on 8-week-old Lewis 1A rats (n = 14). Eleven rats underwent external irradiation on the hind limbs by a single 80-Gy dose. Three rats did not receive irradiation and served as controls for statistical analysis. Eight weeks after the external irradiation, all the animals received a barium sulfate intracardiac injection under general anesthesia. All samples were analyzed with the micro-computed tomography system at a resolution of 5.5 µm. The images were later processed to create 3D reconstructions and study vascularization, bone volume, and cortical thickness. Data from irradiated and nonirradiated rats were compared using the Kruskal-Wallis test. No animal died after irradiation. Nineteen irradiated tibias and six nonirradiated tibias were included for micro-CT analysis. The vessel percentage was significantly lower in irradiated bones (p = 0.0001). The distance between the vessels, a marker of vascular destruction, was higher after irradiation (p = 0.001). The vessels were also more altered distally after irradiation (p = 0.028). Cortical thickness was severely decreased after irradiation, sometimes even reduced to zero. Both trabecular and cortical structures were destroyed after irradiation, with wide bone gaps. Finally, both total bone volume (p = 0.0001) and cortical thickness (p = 0.0001) were significantly decreased in irradiated tibias compared to nonirradiated tibias. These results led to multiple spontaneous fractures in the irradiated group, and the destruction of intraosseous vessels observed macroscopically with the radiographic preview. This study revealed the impact of radiation on intraosseous vasculature and cortical bone with a micro-CT analysis in a rat ORN model. Hypovascularization and osteopenia are consistent with the literature, contributing a morphological scale with high resolution. Visualization of the vasculature by micro-CT is an innovative technique to see the changes after radiation, and should help adjust bone tissue engineering in irradiated bone.

Development of a cyclosporin-A-induced immune tolerant rat model to test marrow allograft cell type effects on bone repair.

Bone repair is an important concept in tissue engineering, and the ability to repair bone in hypotrophic conditions such as that of irradiated bone, represents a challenge for this field. Previous studies have shown that a combination of bone marrow and (BCP) was effective to repair irradiated bone. However, the origin and role played by each cell type in bone healing still remains unclear. In order to track the grafted cells, the development of an animal model that is immunotolerant to an allograft of bone marrow would be useful. Furthermore, because the immune system interacts with bone turnover, it is of critical importance to demonstrate that immunosuppressive drugs do not interfere with bone repair. After a preliminary study of immunotolerance, cyclosporin-A was chosen to be used in immunosuppressive therapy. Ten rats were included to observe qualitative and quantitative bone repair 8 days and 6 weeks after the creation of bone defects. The defects were filled with an allograft of bone marrow alone or in association with BCP under immunosuppressive treatment (cyclosporin-A). The results showed that there was no significant interaction of cyclosporin-A with osseous regeneration. The use of this new immunotolerant rat model of bone marrow allograft in future studies will provide insight on how the cells within the bone marrow graft contribute to bone healing, especially in irradiated conditions.

Oncological and functional outcomes for transoral robotic surgery following previous radiation treatment for upper aerodigestive tract head and neck cancers. A French multicenter GETTEC group study.

BACKGROUND: Transoral robotic surgery (TORS) opens new perspectives. We evaluated the outcomes for patients having undergone TORS after previous radiotherapy. METHODS: A retrospective multicenter study (n = 138) in a previously irradiated area between 2009 and 2020. Survival was assessed with the Kaplan-Meier method. Prognostic factors were evaluated using a chi-squared test, Fisher's test, or Wilcoxon's test. RESULTS: The median length of hospital stay was 12.5 days. Bleeding was the most frequent postoperative complication (15.2%, n = 22). Prophylactic vessel ligation did not significantly decrease bleeding. Complications were significantly lower for Tis, T1, and N0 tumors. 91.6% (n = 120) of the patients with a perioperative tracheotomy could be decannulated. Larynx was functional for 65.94% of the patients. The median length of follow-up was 26 months. The 5-year overall and relapse-free survival rates were respectively 59.9% and 43.4%. CONCLUSION: Oncological and functional results confirmed the value of TORS as a treatment in previously irradiated area.

Study protocol: the biologics in severe chronic rhinosinusitis with nasal polyps survey.

INTRODUCTION: Chronic rhinosinusitis with nasal polyps (CRSwNP) is a frequent condition affecting approximately 2% of the population. Medical treatment consists long-term use of intranasal corticosteroids and short-term use of oral corticosteroids, in adjunct with saline solution rinses. Surgical management is proposed in patients who failed after medical treatment. In France, two biologics are reimbursed in case of severe uncontrolled CRSwNP despite medical treatment and endoscopic sinus surgery. Waiting for head-to-head biologics comparison, studies should report the efficacy and safety of biologics in large real-life cohorts. This study protocol describes the aims and methods of a prospective, observational, national, multicentric cohort of patients with CRSwNP treated with biologics. METHODS AND ANALYSIS: The BIOlogics in severe nasal POlyposis SurvEy is a French multicentre prospective observational cohort study. The main aim is to assess the efficacy and tolerance of biologics in patients with CRSwNP, with or without association with other type 2 diseases, and to determine the strategies in case of uncontrolled disease under biologics. Patients over 18 years old requiring biologics for CRSwNP in accordance with its marketing approval in France (ie, severe nasal polyposis, with lack of control under nasal corticosteroid, systemic corticosteroids and surgery) are invited to participate. Collected data include topical history of surgical procedures and biologics, medication and use of systemic corticosteroids, visual analogical scales for specific symptoms, Sino-Nasal Outcome Test-22 questionnaire, nasal polyp score, asthma control test, Lund-Mackay score on CT scan and IgE concentration and eosinophilic count on blood sample. TRIAL REGISTRATION: NCT05228041/DRI_2021/0030.

Functional or radical surgical treatment of laryngeal chondrosarcoma, analysis of survival and prognostic factors: A REFCOR and NetSarc-ResOs multicenter study of 74 cases.

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.
