Research in Head and Neck Oncology
The Department is active in Head and Neck Cancer research including areas of cancer biology, translational cancer research, novel therapeutics, and clinical trials. Novel therapeutics are offered including immunotherapy, targeted biological treatment, new radiotherapy protocols, and new chemotherapy protocols, not yet available outside the trials. The department offers Transoral Robotic Surgery (TORS) at both the Royal Victoria Hospital of MUHC (Glen site) and the Jewish General Hospital with active trials.
Currently there are many trials on head and neck cancer active and accruing patients within the Department and the McGill Head and Neck Cancer Program. For list of trials on head and neck cancer see https://www.mcgill.ca/rcr-rcn/files/rcr-rcn/head_and_neck_2.pdf
Transotral Robotic Surgery Trials:
ORATOR cooperative trial with TORS was recently completed accrual.
ORATOR II trial with TORS will be activated soon at MUHC and JGH.
NeCTORS Trial: Neoadjuvant Chemotherapy and Transoral Robotic Surgery
Principal Investigator: Nader Sadeghi
Tel: 514-394-1934 Ext 34978
Co-Investigators: Nathaniel Bouganim, Keith Richardson, Alex Mlynarek, Michael Hier
This novel approach has been pioneered by Dr. Nader Sadeghi and is currently open for accrual in a phase II trial. This is a new concept and novel approach for treatment of advanced oropharyngeal cancer associated with Human Papilloma Virus (HPV). The approach includes neoadjuvant (upfront) chemotherapy followed by Transoral Robotic Surgery (TORS ) for definitive management of stage 3 and stage 4A oropharyngeal cancers. Surgery is done via TORS and neck dissection. The trial is designed to start with chemotherapy first. This provides effective systemic treatment to prevent systemic metastasis while it also down-stages the tumor in the neck and the primary site, allowing less invasive yet effective surgery. The trial is unique in its concept and approach in that it is surgery based. It is not radiotherapy based unlike standard treatment options and other ongoing trials for oropharyngeal cancer. It is a paradigm shifting approach that allows avoiding radiotherapy, hence avoiding all side effects and chronic sequellae associated with radiotherapy to the head and neck region.

Psychosocial Oncology Research Program:
The Psychosocial Research Program of the Department is headed by Dr. Melissa Henry. Dr. Henry’s research program aims to implement and evaluate interventions targeting early determinants of mental health, combining translational research with a major focus on head and neck oncology. Patients with head and neck cancer have been understudied despite presenting higher levels of psychological distress, physical symptom burden, and morbidity, compared to patients in general oncology. Dr. Henry is mainly interested in preventing long- term psychological distress trajectories and promoting health through thoughtfully planned early interventions, based on sound modeling including translational research combining the fields of psychology, oncology, and most recently genetics. Her innovative and productive research program has and will continue to have an important impact on identifying algorithms for early recognition of head and neck cancer patients at risk of deteriorated mental health, psychological distress, and quality of life compromise during their illness and treatment trajectory. Her research program is already contributing to our better understanding of the biological component to this biopsychosocial vulnerability in a way that has never been previously done, including the underlying contribution of polygenic risk scores, gene-environment interactions, and immunological processes.

Research Lab: Auditory Mechanics Laboratory
Site: Dept. of Biomedical Engineering, Lyman Duff Medical Sciences Bldg.
Director: W. Robert J. Funnell, PhD Eng., Assoc. Professor
The overall objectives of the research in this laboratory are improved diagnosis and treatment of hearing disorders based on a quantitative understanding of the mechanical behaviour of the middle ear. Our approach involves the development and analysis of three-dimensional finite-element models, an engineering technique that depends heavily on the use of computers. The goal is to enhance the non-invasive clinical evaluation of middle-ear and inner-ear function, especially for newborn hearing screening. The models are also useful for the design of techniques and prostheses for middle-ear surgery.
Our modelling work is done in conjunction with experimental measurements that we make in Dr. Sam Daniel's lab in this department, and also in close collaboration with labs elsewhere in Canada and internationally. We make use of several types of imaging data produced at McGill (for example, clinical CT scans and state-of-the-art nanoCTscans) as well as data from collaborators elsewhere.
We are also involved in research on using 3-D models in anatomy education and in surgical simulation.

The Role of Trigeminal Sensitivity in Chronic Rhinosinusitis
Collaborators: Drs. Johannes Frasnelli, and Maria-Grazia Martinoli
Chronic Rhinosinusitis (CRS) is one of the most common chronic disorders in North America; two very common symptoms described by patients who suffer from this disorder are nasal obstruction (airflow limitation) as well as hyposmia (decreased sense of smell). We hypothesize that the inflammation in the context of a CRS impairs activity and/or density of the TRPM8 receptor, responsible for airflow sensation. We are investigating the association between TRPM8 receptor density and trigeminal sensation in patients with CRS and normal controls.

Tissue Characterization of Inverted Papillomas using Raman Spectroscopy
Collaborators: Drs. Marta Cerruti
Inverted papillomas (IP) are locally invasive tumors of the nasal cavity with a propensity to recur. More importantly, they have a potential for malignant transformation, with carcinoma found in 10% of cases; they therefore require close surveillance. Until now, this surveillance consisted of serial endoscopic examinations and/or imaging studies, with biopsies of suspicious tissue. The modernization of optical diagnostic tools, including Raman spectroscopy (RS), can potentially identify early tumor recurrence based on the biological fingerprint of normal and neoplastic tissue. If shown to be reliable, in-office or intraoperative probes able to read Raman spectra could be used to diagnose IP or help surgeons confirm negative resection margins in real time during surgery.

Development and validation of 3D-printed rhinology surgical training models
Collaborators: Drs. Lily Nguyen, Luc Mongeau, Robert Funnel
With this research, we attempt to answer whether surgical training can be standardized by creating a specific training curriculum that utilizes 3-D printed anatomical models produced at a low-cost allowing trainees to acquire skills at a rate that is comfortable for them. We are hoping to demonstrate that a low cost medium fidelity surgical task trainer designed by our group will allow trainees to practice the surgical skills deemed important in nasal and sinus surgery, and to improve their skills at a rate that is the same or better as traditional learning techniques.

McGill Cochlear Implant Research Program
Program Director: Dr. Anthony Zeitouni, MD
Program Lead Researcher: Alexandre Lehmann, PhD
Cochlear implants can restore audition in deaf individuals; however, successful use of the implant varies widely among individuals. Recovery of function is limited and the responsible mechanisms are unknown. A better understanding of the factors that limit outcomes is critical to maximizing functional recovery and improving rehabilitation strategies.
McGill's CI research program combines clinical and basic hearing research to accomplish three specific objectives: (1) to characterize the brain mechanisms associated with hearing loss and hearing restoration throughout the lifespan; (2) to identify individual factors that impact adaptation and can predict specific outcomes; (3) to develop new strategies that boost the brain's capacity to adapt and improve outcomes. The ultimate goal is to improve outcomes of implantation and rehabilitation programs and to fully understand the factors that promote or inhibit recovery of function.
Our team combines expertise in Otolaryngology, Audiology, and Cognitive Neuroscience with state-of-the-art brain imaging in order to carry out this innovative research successfully. A close collaboration between researchers, clinicians, and knowledge users facilitates the translation of research results into new clinical applications. Significant progress over the past four years demonstrated the feasibility of the program and generated novel knowledge. Seed funding, keynote invitations to international conferences and peer-reviewed scientific communications demonstrate the recognition of our program's excellence by the scientific and medical communities.
