The Value of Volumetric Indicators of PET/CT ¹⁸F-Fluorodeoxyglucose of Patients with Synovial Sarcoma: Two Clinical Cases

Abstract

Synovial sarcoma (SS) is a rare malignant soft tissue tumor that is associated with a high risk of distant metastasis, which significantly reduces patients` life expectancy. The analysis of volume indicators of PET/ CT)with 18F-fluorodeoxyglucose (FDG) was performed in two patients with the same grade of SS malignancy. The presented clinical cases demonstrate that in different patients with similar values 18F- FDG of the standardized uptake value (SUVmax) PET/CT volume indicators such as Metabolic Tumor Volume (MTV) and Total Lesion Glycolysis (TLG) can vary significantly, and therefore they can be additional prognostic factors for overall survival.
