Metabolic Biomarkers Predicting Response to Neoadjuvant Immunotherapy in Non-Small Cell Lung Cancer

Patients will receive neoadjuvant treatment with nivolumab (3 mg/kg, IV) combined with platinum-based chemotherapy (cisplatin 75 mg/m² or carboplatin AUC 5, plus pemetrexed 500 mg/m² for non-squamous or paclitaxel 175 mg/m² for squamous tumors) every 21 days for two cycles. All patients will undergo invasive mediastinal staging before treatment and will be treated with robotic-assisted anatomical lung resection and mediastinal lymphadenectomy after neoadjuvant therapy.
