Brief summary: TPF is still recommended as the preferred induction chemotherapy regimen for nonsurgical treatment of patients with LA HNSCC. Based on the KEYNOTE-048 study, all major guidelines recommend PD-1 monotherapy or PD-1 combined with chemotherapy as the new first-line standard treatment for patients with advanced HNSCC. The immunotherapy in operable LA HNSCC was also explored as neoadjuvant therapy due to the excellent data in advanced HNSCC. These explorations have also achieved good results. Therefore, this study aims to explore the pathological remission rate, the long-term benefit and safety of Tislelizumab combined with albumin paclitaxel, cisplatin and fluorouracil for locally advanced oral squamous cell carcinoma.
