FIGURE 1 Receiver operating characteristic constructed using the sensitivity–specificity relationship circulating vascular endothelial growth factor (VEGF) serum to discriminate non-small cell lung cancer (NSCLC) patients and patients with a nonmalignant pulmonary disease. AUC, area under the curve; SE, standard error. Journal of Thoracic Oncology 2008 3, DOI: ( /JTO.0b013e e) Copyright © 2008 International Association for the Study of Lung Cancer Terms and Conditions

FIGURE 2 Circulating vascular endothelial growth factor (VEGF) serum distribution according to Mountain stage grouping in non-small cell lung cancer (6th edition of the staging system). Horizontal bar, median value; columns, interquartile range; vertical bar, 95% confidence interval. Kruskal–Wallis test: 11.2; p = 0.01.

FIGURE 5 Probability of survival of non-small cell lung cancer patients with normal and elevated pretreatment circulating vascular endothelial growth factor (VEGF) serum level; Kaplan–Meier curves were constructed taking into account the whole population survival. Dotted line, circulating VEGF serum >600 pg/mL; dark line, circulating VEGF serum ≤600 pg/mL. Median survival in months [95% CI]: 6.4 [ ] and 10.6 [ ], respectively, log-rank: p = Journal of Thoracic Oncology 2008 3, DOI: ( /JTO.0b013e e) Copyright © 2008 International Association for the Study of Lung Cancer Terms and Conditions
