Abstract

Purpose: Accurate risk stratification is essential for optimizing radiation therapy for early stage non-small cell lung cancer (NSCLC). This study evaluated whether the consolidation-to-tumor ratio (CTR) or conventional clinical T stage provides superior prognostic value for patients treated with definitive radiation therapy. Methods and Materials: This study included patients with NSCLC with a lesion diameter ≤3 cm, without lymph node or distant metastases, who underwent definitive radiation therapy alone between 2015 and 2022. Patients were categorized into 3 CTR groups: ground-glass opacity (GGO)-dominant (≤0.5), solid-dominant (>0.5 to
