Tislelizumab Combined APF Chemotherapy in the Treatment of Locally Advanced Head and Neck Tumors

A Prospective Single-center, Single-arm Clinical Study of the PD-1 Inhibitor Tislelizumab Combined With APF Sequential Surgery or Radical Concurrent Chemoradiotherapy in the Treatment of Locally Advanced Head and Neck Tumors
