This study evaluated the utility of Coronary Artery Calcification (CAC) score and Routine Blood Test (RBT) score in predicting the 5-year survival rate of resected Stage I Lung Cancer patients. Analysis of 536 patients showed a trend of lower survival rates with higher CAC scores (CAC ≥400: 73.5%, CAC 100-399: 77.5%, CAC <100: 84.7%). Additionally, patients with high RBT scores had increased mortality risk. Aview by Coreline Soft was used for automated CAC measurement, and combining it with RBT scores provided a more precise predictive model. The findings suggest that considering both CAC and RBT scores improves survival prediction accuracy, enabling tailored management strategies for early-stage Lung Cancer patients.
