Oral Cavity Neoplasm

This clinical trial studies wide-field and high resolution in vivo imaging in visualizing lesions in patients with abnormal or uncontrolled oral cell growth (neoplasia) undergoing surgery. Diagnostic procedures, such as wide-field and high resolution in vivo imaging, are devices that let researchers look at a wide area of the lining of the mouth by shining different colors inside the mouth and taking pictures and this may help doctors to decide if a mouth lesion has a high risk of being pre-cancerous or cancerous.

This phase II study evaluates the efficacy and safety of neoadjuvant chemoimmunotherapy consisting of camrelizumab (PD-1 inhibitor), paclitaxel, and carboplatin in patients with resectable locally advanced (Stage III-IVA) squamous cell carcinoma of the oral cavity and/or larynx. Fifty patients will receive 3 cycles of therapy (camrelizumab 200 mg IV, paclitaxel 175 mg/m2 IV, carboplatin AUC6 IV, Day 1 every 21 days) followed by radical surgery 4-6 weeks later. Patients are then stratified to risk-adapted adjuvant therapy based on pathological findings (radiation or chemoradiation with cisplatin if adverse features present). The primary endpoint is the pathological complete response (pCR) rate and major pathological response (MPR, \<10% viable tumor cells) rate at surgery. Secondary endpoints include objective response rate (ORR) by imaging (MRI/PET-CT), correlation of PET-CT metabolic response with pathological response, proportion requiring adjuvant chemoradiation, and 3-year event-free survival compared to historical controls. Study period: 2026-2029.
