Discrepancy Between Preoperative CT and Pathological Tumor Diameters in Stage I Lung Adenocarcinoma and Its Association with Postoperative Recurrence

Puntos clave

Evaluate the differences between CT and pathological measurements of tumor size and their impact on postoperative recurrence.
Analyzed preoperative CT and pathological measurements of tumor diameters
Identified discrepancies greater than 3 mm
Examined associations with postoperative recurrence risk
CT measurements typically overestimate tumor sizes
Discrepancies greater than 3 mm correlate with increased recurrence risk
Incorporating these discrepancies into risk models could enhance stratification

Resumen

CT measurements tend to overestimate tumor size, and excessive overestimation (difference >3 mm) was independently associated with higher postoperative recurrence risk. Incorporating CT-pathology discrepancies into prognostic models may improve postoperative risk stratification.
