Tongue Squamous Cell Carcinoma

The goal of this study is to evaluate the safety and effectiveness of EVOLVE104 in participants with advanced urothelial and squamous cell carcinomas who have previously taken standard treatment options, have declined or have been ineligible for treatment with these medications. Participants with advanced or metastatic cancer who meet all eligibility criteria may be eligible to participate in the study.

This phase II/III trial studies how well sentinel lymph node biopsy works and compares sentinel lymph node biopsy surgery to standard neck dissection as part of the treatment for early-stage oral cavity cancer. Sentinel lymph node biopsy surgery is a procedure that removes a smaller number of lymph nodes from your neck because it uses an imaging agent to see which lymph nodes are most likely to have cancer. Standard neck dissection, such as elective neck dissection, removes many of the lymph nodes in your neck. Using sentinel lymph node biopsy surgery may work better in treating patients with early-stage oral cavity cancer compared to standard elective neck dissection.

The objective of this exploratory clinical trial is to apply Unreal Engine 5 (UE5)-based Mixed Reality (MR) technology to achieve real-time stereoscopic visualization of surgical planning, personalized free flap harvest and defect reconstruction, accurate oral cancer resection, and precise morphological and volumetric matching of the reconstructed free flap to the defect site. Researchers adopted a parallel controlled design, with participants randomized into three groups: Experimental Group 1 (undergoing Mixed Reality \[MR\] technology-assisted surgery), Experimental Group 2 (undergoing virtual surgical guide-assisted surgery), and Control Group (undergoing conventional surgery). A total of 30 participants will be recruited, with 10 cases in each group. The primary purpose is to confirm the effectiveness of MR technology in assisting oral cancer resection, free flap design, harvest, and defect reconstruction. Allocation concealment will be implemented via the sealed envelope method.

The goal of this clinical trial is to evaluate the feasibility and preliminary efficacy of lingual nerve disruption combined with neoadjuvant chemoimmunotherapy in patients with locally advanced tongue squamous cell carcinoma. The study aims to learn whether surgical disruption of the lingual nerve can enhance the effectiveness of neoadjuvant chemoimmunotherapy before definitive surgery in adults with locally advanced (cT3/T4) tongue cancer. The main questions it aims to answer are: Can lingual nerve disruption combined with neoadjuvant chemoimmunotherapy improve tumor response prior to surgery? Is this combined treatment approach safe and feasible for patients with locally advanced tongue cancer? This is a single-arm, phase II clinical trial. Participants will: Undergo tumor biopsy with simultaneous surgical disruption of the affected-side lingual nerve. Receive neoadjuvant chemoimmunotherapy consisting of tislelizumab, cisplatin, and nab-paclitaxel for two treatment cycles. Undergo definitive surgical resection of the primary tumor and neck dissection. Attend scheduled follow-up visits for safety assessments, imaging evaluations, and collection of blood samples for immune monitoring.
