Squamous Cell Cancer of Head and Neck (SCCHN)

The goal of this Phase 1 clinical trial is to evaluate the safety and feasibility of nivolumab-IRDye800CW (nivo800) as a molecular imaging agent in adults with biopsy-confirmed or presumed head and neck squamous cell carcinoma (HNSCC) who are scheduled to undergo standard-of-care surgical resection. The main questions it aims to answer are: * Is nivolumab-IRDye800CW (nivo800) safe when administered before surgery, as measured by the occurrence of clinically significant Grade ≥2 adverse events that are possibly, probably, or definitely related to the study drug? * What is the extent of pathological response at each dose level, including residual viable tumor, fibrosis, necrosis, and tumor-infiltrating lymphocyte characteristics? Participants will: * Receive two intravenous infusions during the preoperative period, approximately 2-3 weeks before surgery and again 1-2 days before surgery. * Undergo standard-of-care surgical resection with collection of tumor and lymph node specimens for pathological and imaging studies.

The main objective of this trial was to determine the value of concurrent chemoradiotherapy for Intermediate-risk head and neck squamous cell carcinoma

This is a randomized, single centre, single blinded prospective study comparing the standard of care imaging guided radiation therapy and daily adaptive radiotherapy (ART) for submandibular gland-sparing in head and neck cancer

This phase 1 multi-site study investigates the safety and initial effectiveness of focused ultrasound lesioning of the contralateral mesencephalon for severe, opioid-resistant pain associated with head and neck cancer and brachial cancer.

The goal of the study lies in offering a multimodal analysis of the post-therapeutic response based on both quantitative parameters and radiomics (CT, MRI, and PET imaging), and on tumor biology, in particular the hypersensitive detection of tumor DNA.
