| Outline of Final Research Achievements |
The aim of this study was to investigate the relationship between the tumor uptake of 16α-(18)F-fluoro-17β-estradiol ((18)F-FES) and (18)F-FDG using PET and expressions of sex hormone receptors, such as estrogen receptor (ER), as well as glucose transporter 1 (GLUT-1) and Ki-67 analyzed by the immunohistochemistry method in mesenchymal uterine tumors.
Correlation analysis showed accumulution of (18)F-FES and (18)F-FDG PET showed correlations between tracer uptake and expressions of sex hormone receptors, GLUT-1, and Ki-67 in mesenchymal uterine tumors. The (18)F-FDG/(18)F-FES ratio was correlated with Ki-67, GLUT-1, and ERβ in uterine sarcoma. Functional PET imaging and PET parameters would be useful noninvasive biomarkers for the assessment of tumor hormone receptor expression, glucose metabolism, and proliferation and for differential diagnosis of uterine leiomyoma and sarcoma.
