Workshops and Exchange Groups for Laryngectomized Patients

This research is conducted with the aim of improving the quality of life of laryngectomized patients and their entourage. Worldwide, there are 185,000 new cases of laryngeal cancer per year. In Europe, between 2000 and 2007, the crude annual incidence rates of these cancers were 4.6/100,000 with a 5-year survival rate of 61%. In France, about 30 to 35% of cancers of the upper aerodigestive tract are localized to the larynx, or about 43,000 cases per year. Most patients are men (89%) between 50 and 70 years old. One of the treatments for these cancers is to perform an excision of the larynx thus removing the entire tumor, it is the total laryngectomy. The trachea is thus permanently removed from the skin and the digestive tract becomes independent.

Neoadjuvant Chemotherapy and Programmed Cell Death Protein 1(PD-1) Inhibition for Head and Neck Cancer Treatment De-escalation (NeoScorch HN)

The NeoScorch HN study is a single institution multisite phase II trial including 3 cohorts of 25 patients each for patients with newly diagnosed locoregionally advanced, histologically confirmed, head and neck cancer eligible for curative-intent treatment, who will receive neo-adjuvant chemoimmunotherapy-based treatment as well as standard of care adjuvant treatment. The three cohorts include three different aspects of surgical de-escalation in head and neck cancer. The first cohort includes human papillomavirus independent (HPV-) squamous cell carcinoma of the head and neck. The second cohort includes HPV-associated head and neck cancer with radiographic evidence of extranodal extension in neck lymphadenopathy. The third cohort specifically includes malignancies of the sinonasal cavity and skull base which have a propensity for invasion of the orbit, skull base, and maxilla. Surgical treatment of all three of these cohorts has significant morbidity including swallowing, speech, and vision among others.

Integrated Cancer Repository for Cancer Research

The iCaRe2 is a multi-institutional resource created and maintained by the Fred \& Pamela Buffett Cancer Center to collect and manage standardized, multi-dimensional, longitudinal data and biospecimens on consented adult cancer patients, high-risk individuals, and normal controls. The distinct characteristic of the iCaRe2 is its geographical coverage, with a significant percentage of small and rural hospitals and cancer centers. The iCaRe2 advances comprehensive studies of risk factors of cancer development and progression and enables the design of novel strategies for prevention, screening, early detection and personalized treatment of cancer. Centers with expertise in cancer epidemiology, genetics, biology, early detection, and patient care can collaborate by using the iCaRe2 as a platform for cohort and population studies.

Validation of End-to-End Difficult Airway Pathway Planning Algorithm (EAP-LC)

Patients with laryngeal cancer often present with varying degrees of airway narrowing or anatomical distortion, making airway management particularly challenging. Awake flexible bronchoscopic intubation is a widely accepted and important strategy to ensure airway safety in this population. Currently, the selection of the intubation pathway mainly relies on visual assessment of preoperative computed tomography (CT) images and the clinical experience of anesthesiologists, lacking objective and quantifiable tools for airway pathway planning. Our research group has developed an end-to-end airway pathway planning algorithm for laryngeal cancer patients (EAP-LC), which can automatically generate predicted nasal or oral intubation pathways based on preoperative pharyngeal and upper airway CT images. Preliminary simulation analyses based on retrospective CT data demonstrated that the algorithm is capable of identifying airway narrowing and generating trajectories that are close to clinically feasible intubation paths (preliminary data, under review). However, to date, no study has directly compared the algorithm-predicted pathways with actual intubation trajectories obtained during awake flexible bronchoscopic intubation. Therefore, a prospective clinical validation study is required to evaluate the spatial consistency and clinical feasibility of the EAP-LC algorithm. Without altering routine clinical treatment or anesthetic management, this study aims to evaluate the clinical accuracy, safety, and feasibility of the EAP-LC algorithm by comparing the intubation pathways predicted from preoperative CT images with the real-world trajectories recorded during awake flexible bronchoscopic intubation. The results of this study are expected to provide a more precise and objective decision-support tool for airway management in patients with laryngeal cancer.

The Voice as a Tool to Detect Recurrence of Laryngeal and Hypopharyngeal Cancer

The investigators will obtain three-monthly voice recordings and fiberendoscopic examinations of the larynx/hypopharynx for a minimal period of 6 months from all laryngeal/hypopharyngeal squamous cell carcinoma (LSCC/HPSCC) patients, who have successfully completed curative primary treatment, except those who underwent total laryngectomy. Furthermore, the investigators will ask the patients to fill out the voice handicap index-30 questionnaire (VHI-30) during each study visit. The VHI-30 allows to make a subjective assessment of the patients' own vocal problem. The primary objective is to assess the feasibility and compliance of longterm regular voice monitoring in LSCC and HPSCC follow-up.

Thermoradiotherapy for Locally Advanced Head and Neck Cancer Patients

Patients with head and neck cancer treated with radiotherapy (RT) have a substantial change of recurrence of the tumor in the pharynx or lymph nodes in the neck. Once tumor and/or lymph nodes have recurred, the prognosis is poor. To increase the efficacy of RT, usually chemotherapy is added to the treatment. However, due to age or co-morbidity chemotherapy is not always feasible to give in all patients. In head and neck patients unfit for chemotherapy, there is a clinical need to increase the effectiveness of RT, without adding substantial toxicity. To this end, the use of thermotherapy in this disease site is investigated. The goal of this clinical trial is to learn about the recommended dose of thermotherapy in addition to radiotherapy for patients with head and neck cancer. This recommended dose is the dose that is tolerable and does not give additional side effects. The main question our study aims to answer is: "What is the recommended dose of thermotherapy for patients with primary head and neck cancer treated with radiotherapy?" Participants will receive thermotherapy once a week in addition to the standard radiotherapy. Researchers will investigate if side effects occur during the treatment and until 6 months after the last treatment has been given. The thermotherapy will be applied using a device that was made in Erasmus MC and allows for precise heating of the tumor and lymph nodes.

SBRT Followed by Chemoimmunotherapy of Toripalimab Plus Docetaxel and Cisplatin for Larynx Preservation in Patients with Locally Regionally Advanced Squamous Cell Carcinoma of the Larynx and Hypopharynx

This trial aims to evaluate the safety and efficiency of SBRT followed by Chemoimmunotherapy of Toripalimab Plus Docetaxel and Cisplatin for Patients with Locally Regionally Advanced Squamous Cell Carcinoma of the Larynx and Hypopharynx

European Larynx Organ Preservation Study (ELOS) [MK-3475-C44]

ELOS is a prospective, randomized, open-label, controlled, two-armed parallel group, phase II multicentre trial in local advanced stage III, IVA/B head and neck squamous cell carcinoma of the larynx or hypopharynx (LHNSCC) with PD-L1-expression within tumor tissue biopsy, calculated as CPS ≥ 1 curable by total laryngectomy. Induction chemotherapy (IC) with Docetaxel and Cisplatin (TP) followed by radiation will be compared to additional PD-1 inhibition. Patients will be selected after short induction early response evaluation after the first cycle IC (IC-1) aiming on larynx organ-preservation by additional 2 cycles IC followed by radiotherapy (69.6 Gy) for responders achieving endoscopic estimated tumor surface shrinkage (ETSS) ≥ 30%. Nonresponders (ETSS \< 30% or progressing disease) will receive total laryngectomy and selective neck dissection followed by postoperative radiation or chemoradiation according to the recommendation of the clinics multidisciplinary tumor board. However, Patients randomized into the intervention arm starting day 1 will receive 200 mg Pembrolizumab (MK-3475) i.v. in 3-week cycle (q3w) for 17 cycles (12 months). Treatment with pembrolizumab will continue in the experimental arm regardless of ETSS status after IC-1 in both responders and laryngectomized nonresponders, independent from subsequent decision on adjuvant therapy after TL.

Tislelizumab and Induction Chemotherapy for Larynx Preservation in Resectable Advanced Laryngeal/Hypopharyngeal Cancer

This study is a prospective, single-arm, single-center, phase II study. The goal of this clinical trial is to explore the therapeutic value of the treatment model of "tislelizumab combined with chemotherapy followed by radiotherapy/adaptive surgery" on larynx Preservation of locally advanced hypopharyngeal cancer and laryngeal cancer.

Immune Biomarker Study for Head and Neck Cancer

The aim of this prospective non-interventional multi-center trial is to study the prognostic value of intratumoral and systemic immune biomarkers in newly diagnosed non-metastatic head and neck cancer. Furthermore, the local immunological processes in the tumor will be correlated with the systemic immune status determined in the peripheral blood to identify prognostic immune signatures. In addition, tumor organoids will be generated ex vivo for functional biological analyses. The main objective is to create a prognostic score determined by clusters based on tumor immunologic criteria.

Aortic Laryngeal Rehabilitation Graft

The larynx is a cartilaginous organ of the respiratory system located in the throat, which plays an essential role in respiratory function, swallowing and sound production. In the case of advanced tumours, the surgical option most often remains total laryngectomy, with the corollary of a major impact on quality of life, not so much because of the loss of voice, but because of the presence of a definitive tracheostoma with particularly deleterious consequences. The majority of the work of the different teams around the world has focused on restoring phonatory function, but no technique - apart from the artificial larynx developed in the ENT department of the Hautepierre Hospital - has yet succeeded in removing the tracheotomy orifice, requiring the restoration of a common passage between the respiratory and swallowing passages. If nutrition and phonatory function can still be supplemented after such an operation (oesophageal rehabilitation, implant placed between the trachea and oesophagus), natural breathing is no longer possible. Patients are forced to wear a permanent tracheotomy opening. There are currently only 2 ways to try to restore all the functions of the larynx after total laryngectomy: i) laryngeal transplantation, but this procedure requires maintaining immunosuppressive treatment, which is not possible in patients suffering from cancer of the larynx, which is not a vital organ, ii) artificial larynx made of biomaterials (titanium), the first cases of which were performed worldwide in the ENT department of the Strasbourg University Hospital in 2012, results published in the NEJM (API 2008-2009 HUS No. 4493- IDRCB No.: 2011-A00032-39. However, difficulties were encountered with the use of the titanium prosthesis due to the bulk and rigidity of the removable and non-removable part, which caused residual swallowing difficulties (false routes). It is now possible, due to the development of new allograft techniques in humans for tracheal replacement (studies published on a large number of cases with several years of hindsight, cf. references), to switch to the "all biological" using an aortic graft stented with a silicone stent. We wish to use these grafts in laryngeal restoration after total laryngectomy by our team, while exploiting all the data and experience acquired (unique in the world) within the ENT department of Hautepierre Hospital. This new conceptual leap should make it possible to significantly improve the patient's quality of life and the performance previously acquired in clinical trials on the artificial larynx in its entirety (breathing, phonation) or partially (swallowing). The investigators thus propose to evaluate this new artificial larynx in aortic allograft, the objective of which is to supplement the respiratory, swallowing and phonation functions in patients laryngectomized for carcinological causes.
