Cross-sectional study investigates FDG PET biomarkers' correlations with tumor characteristics, indicating potential for improved diagnostic accuracy.

Key Points

This research aims to evaluate the correlations between FDG PET biomarkers and various tumor characteristics in lung carcinoma.
Conducted a cross-sectional analysis of 45 patients with FDG-avid lung carcinoma.
Measured FDG PET biomarkers (SUVmax, TLG, MTV) alongside histopathological and biochemical markers.
Utilized Pearson and Spearman tests for correlation analysis and multivariate regression for predictor identification.
SUVmax positively correlated with tumor size across all stages (r = 0.68, p < 0.001).
Stronger correlations observed in advanced stages: Stage II (r = 0.75, p = 0.02) and Stage III (r = 0.80, p = 0.01).
Significant correlation between TLG and MTV (r = 0.89, p < 0.001) and higher SUVmax in squamous cell carcinoma compared to adenocarcinoma.
