NSCLC, Stage I

A randomized trial of adjuvant Pembrolizumab following surgical resection versus observation following surgical resection in patients with stage I non-small cell lung cancer (NSCLC) with primary tumors between 1-4 cm. Patients will be randomized (1:1) 4-12 weeks following surgery to either: * Arm A: Pembrolizumab 400 mg every 6 weeks × 9 cycles * Arm B: Observation Stratification factors will include: PD-L1 TPS (\<50% vs. ≥50%), and tumor size (1-2 cm vs. \>2-4 cm)

The purpose of this study to find out whether giving BIO 300 in combination with thoracic radiation therapy is effective in preventing pneumonitis in people with non-small cell lung cancer (NSCLC) and interstitial lung disease (ILD).

This is a non-interventional, retrospective observational study to improve knowledge regarding the diagnosis and treatments of patients who have/had non-small cell lung cancer (NSCLC), either early stage (stage I-II).

This is a prospective, open, single-center, single-arm phase II clinical study with common EGFR-sensitive mutations (Ex19del and L858R) identified in the central laboratory.To evaluate the efficacy and safety of adjuvant Osimertinib therapy in completely resected stage I non-squamous non-small cell lung cancer (NSCLC) with high-risk factors (solid and/or micropapillary component ≥10%, and/or airway spread).
