Neoadjuvant Low-Dose Radiotherapy Combined With Adebrelimab and Single-Agent Albumin-Bound Paclitaxel Chemotherapy for Early-Stage Oral Squamous Cell Carcinoma: A Prospective, Single-Arm Clinical Trial

This is a prospective, single-arm, Phase II clinical trial. The included population consisted of untreated patients with histologically confirmed stage I-II oral squamous cell carcinoma. Eligible patients received neoadjuvant low-dose radiotherapy combined with adibelizumab and monotherapy with albumin paclitaxel for two cycles. Radical surgical resection is planned to be carried out 3 to 4 weeks after neoadjuvant therapy. Patients who obtain PCR after evaluation by the researchers after the operation will be maintained for 6 cycles of immunomonotherapy. The primary endpoints were the rate of pathological response and the rate of exemption from cervical lymph node dissection. The secondary endpoints included progression-free survival, local control rate, distant metastasis-free rate, overall survival, safety and quality of life of patients, as well as the exploration of biomarkers
