HN-BIO 02: A Phase II Randomized Study of the Effects of Delayed Elective Radiotherapy on Head and Neck MRI and Immune Response BiomarkersThis is a single centre prospective exploratory study of effects of delayed radiation therapy on adaptive immune response in patients with newly diagnosed (head and neck squamous cell carcinoma) HNSCC receiving curative radiotherapy. This research is part 2 of the HN-BIO study.	Cancer	Non applicable		Canada	À vérifier
LIFUSLow intensity focused ultrasound (LIFUS) has the potential to be used as a means of non-invasive neuro-modulation. To this day, the use of LIFUS is under investigation. Studies in healthy subjects have shown that application of LIFUS to the motor region of the brain can mildly decrease neuron excitability in healthy controls. The purpose of the present study is to evaluate the effects of LIFUS on brain tissue excitability in patients with movement disorders in order to elucidate the therapeutic potential of LIFUS.

Magnetic Resonance Guided Focused Ultrasound ThalamotomyBackground: Accessing brain tumor material for pathological diagnosis requires invasive procedures that carry risk to patients including brain hemorrhages and death. Liquid biopsies are emerging non-invasive alternatives to direct tumour biopsies but the abundance of circulating tumor DNA (ctDNA) is relatively low and this limits our ability to accurately make the molecular diagnosis of brain tumors. We have recently shown promising results that suggest that the analysis of blood samples can distinguish brain tumor types. We now want to couple liquid biopsies with high intensity focused ultrasound (HIFU) to enhance the release of tumor DNA into the circulation and increase the sensitivity/and specificity of liquid biopsies for brain tumors. The aim of this project is to build on our preliminary findings and investigate the the time dependent changes associated with HIFU of a tumor to see if it improves accuracy of diagnosis and specifically molecular subtyping of tumors based on peripheral blood and cerebrospinal fluid (CSF) circulating tumor derived markers following HIFU.

Radiofrequency Ablation of Papillary Thyroid CancerThis pilot, single-arm clinical study evaluates the feasibility, safety, and effectiveness of radiofrequency ablation (RFA) as a curative treatment for small, low-risk papillary thyroid cancer (PTC). The study will enroll 30 adult patients (≥18 years) with biopsy-confirmed PTC measuring \<2 cm, who decline surgery or active surveillance, or who are transitioning from active surveillance to active treatment. Eligible participants will undergo ultrasound-guided RFA performed with curative intent at University Health Network. Patients will be followed for up to 12 months with scheduled clinical visits, neck ultrasounds, blood tests, voice assessments, and patient-reported outcome questionnaires. A biopsy of the ablation site at 6-12 months will be used to assess local cancer control. The primary objective is to determine the local cure rate and safety profile of RFA for low-risk PTC. Secondary objectives include evaluating post-ablation ultrasound features, patient-reported quality of life, and the feasibility of implementing a multidisciplinary thyroid RFA program within routine clinical practice. Results from this study will provide important preliminary data to inform future larger trials comparing RFA with surgery and active surveillance for selected patients with low-risk papillary thyroid cancer.

Stereotactic Ablative Body Radiotherapy (SABR)This Phase II Prospective, parallel and open-label randomised control trial will investigate whether a radiotherapy technique (called SABR) can treat early stage liver cancer more effectively than current treatments which use heating probes directly inserted into the tumour or chemotherapy or radioactive particles injected into the blood supply of the tumour. Investigators hypothesize SABR will result in higher rates of freedom from local progression (FFLP) at 2 years compared to percutaneous thermal ablation ± TACE or transarterial therapies (TACE/TARE).The study will also look at other important outcomes such as progression free survival, overall survival, side effects, quality of life and people's experiences of their treatment.
