Abstract
Aim. To evaluate a value of the proliferation activity assessment in gliomas using PET/CT with the application of 18F-fiuorothymidine.
Method. The sample of 21 tumors was analyzed (in patients with mean age 50.3, range 26-72 years), 18F-FLT-PET/CT was performed before confirmation of the histological diagnosis, and the level of 18 F-FLT accumulation was compared with the assessment of proliferation activity using immunohistochemistry evaluation of Ki-67.
Results. Following results were reached accuracy 90.4% (19/21), sensitivity 90% (9/10), specificity 90.9 (10/11), positive predictive value 90% (9/10) and negative predictive value 90.9% (10/11).
Conclusion. 18F-FLT-PET/CT is the valuable test to estimate the proliferation activity of gliom before biopsy, could leads to better targeting biopsy and early detection of malignant turnover of glioma.
