Abstract

We aimed at exploring the feasibility of noninvasive late arterial phase enhanced CT imaging in evaluating tumor angiogenesis, ischemic necrosis, and glucose metabolism, thereby providing pathological information for the comprehensive treatment plan in non-small cell lung cancer (NSCLC). 52 cases of NSCLC were enrolled in this study. The mean ischemia necrosis CT quantitative value (INCTQ) and CT enhanced value (CTe) of the tumor were determined, and the immunohistochemical staining of factors relating to tumor angiogenesis, ischemic necrosis and glucose metabolism, including VEGF, VEGFR-2, HIF-1α, CAIX, GLUT1, and GLUT3, were conducted. The mean INCTQ values of different expression grades of VEGF, VEGFR-2, HIF-1α, and CAIX have no significant difference, but the mean INCTQ values of different expression grades of GLUT1 or GLUT3 have significant differences (p < 0.001), respectively. However, INCTQ value has a positive correlation with CAIX expression. In addition, CTe value was positively correlated with VEGF. To sum up, late arterial phase CT enhanced images of NSCLC not only can assess the tumor angiogenesis, but also can reflect the degree of ischemic necrosis, effectively reflecting the level of glucose metabolism in tumor...Continue Reading
