"The patients in this arm will receive 3 cycles of induction treatment containing chemotherapy with gemcitabine and cisplatin/carboplatin, plus toripalimab. Then the ones without progressive disease will receive radical radiotherapy, plus 2 cycles of concurrent toripalimab.~Toripalimab: 240 mg on Day 1, every 3 weeks, totally 3 and 2 cycles in the induction and concurrent phases, respectively."
