dc.description.abstractBACKGROUND: We evaluated glucose transporter type 1 (GLUT1) and carbonic anhydrase IX (CAIX) expression, together with volume-based(18)F-fluorodeoxyglucose positron emission tomography (FDG-PET) parameters, in non-small cell lung cancer (NSCLC) patients, and examined the prognostic significance of those parameters according to its histologic subtype.
METHOD: A total of 269 patients, who underwent surgical resection for NSCLC, were reviewed retrospectively. Metabolic tumor volume (MTV) and total lesion glycolysis (TLG) values were measured by preoperative (18)F-fluorodeoxyglucose positron emission tomography computed tomography. GLUT1 and CAIX expression was evaluated using immunohistochemical method.
RESULTS: The mean MTV and TLG values were 30.0+/-57.1 and 165.4+/-361.3, respectively, and were significantly higher in patients with squamous cell carcinoma than with adenocarcinoma (p=0.047 for MTV: p=0.042 for TLG). GLUT1 expression was identified in 99% of squamous cell carcinoma and 50% of adenocarcinoma patients. MTV and TLG values were significantly higher in GLUT1-positive than GLUT-negative adenocarcinomas: however, CAIX expression did not show this pattern. GLUT1-positive adenocarcinoma patients had a lower OS than GLUT1-negative patients (p<0.001), whereas CAIX-positive and CAIX-negative patients showed similar OS rates (p=0.226). Patients with high MTV and TLG values showed lower OS rates than those with low MTV and TLG values. Multivariate analysis showed that GLUT1 positivity was an independent risk factor for a lower OS rate in lung adenocarcinoma patients (hazard ratio=2.574, p=0.016). GLUT1 expression was associated with micropapillary/solid histology, lymphovascular invasion, and advanced pTNM stage.
CONCLUSIONS: MTV and TLG values, and GLUT1 expression, significantly differed between patients with squamous cell carcinoma and adenocarcinoma. High GLUT1 expression levels were significantly associated with MTV and TLG values and adverse clinical outcomes in patients with adenocarcinoma.
