Interventions
Gemcitabine + cisplatin: Gemcitabine, 1,000 mg/m², Q3W, d1+d8, IV drip; cisplatin, 80 mg/m², Q3W, d1-3, IV drip. A total of 3 cycles. (Note: Gemcitabine can be replaced by docetaxel, albumin-bound paclitaxel, paclitaxel, etc.)
Tislelizumab 200 mg , once every 3 weeks (Q3W), intravenous infusion (iv). A total of 12 courses of treatment will be administered, including 3 courses during the induction chemotherapy phase, 3 courses during the radiotherapy phase, and 6 courses during the post-radiotherapy maintenance phase. Administration will start on Day 1 of induction chemotherapy and continue after the end of radiotherapy until the occurrence of intolerable toxicities, disease progression, withdrawal of consent, determination by the investigator that the patient needs to withdraw from treatment, or the completion of 12 courses, whichever comes first.
