Conditions

Resectable, driver gene-negative stage IIB-IIIB non-small cell lung cancer

Interventions

Test group:Eligible patients will undergo a neoadjuvant regimen of stereotactic body radiotherapy (SBRT) immediately followed by immunotherapy: the gross tumour volume (GTV), contoured on fused 18F-FD
immunotherapy with apaloritovorilimab 5 mg kg?1 is initiated within seven days after SBRT and administered intravenously every three weeks for two cycles. Post-operatively, the same dose and schedule
