Summary
Brief summary (as posted)
This study investigates metabolic glycolytic biomarkers obtained from radiological imaging (18F-FDG PET/CT), immunohistochemistry (IHC), and molecular analyses, and their association with response to neoadjuvant immunotherapy in early-stage non-small cell lung cancer (NSCLC). Objective: To evaluate the relationship between glycolytic biomarkers measured by PET/CT (metabolic tumor volume and SUVmax), IHC markers (GLUT-1, Ki-67, PD-L1), and molecular oncogenic alterations, with the pathological response after two cycles of neoadjuvant nivolumab (3 mg/kg) combined with platinum-based chemotherapy in patients with early-stage NSCLC \[stage IB (tumor ≥4 cm) to IIIA\], negative for EGFR and ALK mutations. Methods: This is a prospective, single-arm clinical study at a single institution, enrolling 30 patients. Baseline metabolic tumor volume (MTV) and SUVmax will be measured by PET/CT, while IHC markers and molecular profiling will be performed on pre-treatment biopsy samples. 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. Primary outcomes include major pathological response (≤10% viable tumor cells) and immune profile characterization (IHC for CD8, CD4, FOXP3, PD-1, CD68, CD163). Secondary outcomes include event-free survival and treatment toxicity. Standard of Care: Neoadjuvant chemotherapy regimens and PET/CT scans are part of the institutional standard of care for NSCLC patients. Conclusion: The study aims to develop a practical diagnostic approach using metabolic glycolytic biomarkers to improve selection of patients likely to benefit from neoadjuvant immunotherapy. It is expected that patients with lower glycolytic activity will have higher rates of major pathological response after two cycles of neoadjuvant nivolumab (3 mg/kg) combined with chemotherapy. These findings may support a more cost-effective immunotherapy regimen for early-stage NSCLC.

- description
- Patients with resectable non-small cell lung cancer (NSCLC) clinical stage IB-IIIA (AJCC 8th edition) will receive two cycles of neoadjuvant nivolumab at 3 mg/kg combined with platinum-based doublet chemotherapy. Invasive mediastinal staging will be performed prior to neoadjuvant treatment. Following completion of systemic therapy, patients will undergo minimally invasive surgery (preferably robotic-assisted anatomical resection and mediastinal lymphadenectomy).
