Tamura M, Matsumoto I, Tanaka Y, et al. - This study was attempted to explore the ability to use mean computed tomography (mCT) values to prognosticate non-small cell lung cancer (NSCLC) tumor recurrence. Researchers performed a retrospective study on 494 patients with stage IA NSCLC. They used receiver operating characteristics analysis to evaluate the ability to use mCT value, C/T ratio, tumor size, and SUV to predict tumor recurrence. The independent variables for the prediction of tumor recurrence were ascertained by performing multiple logistic regression analyses. The results showed that the assessment of mCT values was beneficial for predicting recurrence after the limited resection of small-sized NSCLC, and may potentially contribute to the selection of suitable treatment strategies.
