ABSTRACT
BACKGROUND:
This study was designed to evaluate the FDG uptake ratio of mediastinal node and primary tumors using integrated PET/CT imaging combined with Glut-1 expression of the primary tumor in order to predict the N2 status more accurately in NSCLC patients. MATERIAL ANDMETHOD:
Patients who underwent integrated PET/CT scanning with a detectable mSUV for both primary tumors and mediastinal lymph nodes were eligible for this study. The FDG uptake ratio between the mediastinal node and the primary tumor was calculated.RESULT:
The average mSUV of primary tumors and mediastinal nodes were, respectively, 7.4+/-2.2 and 4.2+/-2.2 in N2-positive patients and 7.6+/-3.7 and 2.8+/-6.9 in N2-negative patients. The mean FDG uptake ratio of mediastinal node to primary tumor were 0.58+/-0.23 for malignant N2 lymph nodes and 0.45+/-0.20 for benign lymph nodes (p<0.05). Models which combined Glut-1 expression with an FDG ratio have better diagnostic power than models that use the FDG uptake ratio alone.CONCLUSION:
In some patients with a previous history of pulmonary tuberculosis or other inflammatory lung diseases, an FDG uptake ratio combined with Glut-1 expression may be useful in diagnosing mediastinal node metastasis more exactly.
