In this study, we aimed to evaluate the prognostic significance of adipose tissue distribution and metabolic activity in PET/CT predict survival patients with metastatic colorectal cancer (mCRC). The volume, density (HU), FDG uptake (standardized value (SUV)) visceral (VAT) subcutaneous (SAT) maximum tumor were measured. Subcutaneous volume-to-density ratio (SAT ratio) was calculated. median OS...
Abstract Background Stereotactic ablative radiation therapy (SABR) is effective in treating inoperable stage I non-small cell lung cancer (NSCLC), but imaging assessment of response after SABR difficult. This prospective study aimed to develop a predictive model for true pathologic complete (pCR) using imaging-based biomarkers from dynamic [ 18 F]FDG-PET and CT Perfusion (CTP). Methods Twenty-s...
A 52-year-old man presented with subacute thyroiditis and showed an intensely hypermetabolic thyroid lesion on (18)F-FDG PET/CT. The patient also had coexisting chronic lymphocytic thyroiditis. The lesion of subacute thyroiditis revealed an SUV(max) of 9.1 g/mL and was ill-defined, heterogeneous, markedly hypoechoic, and hypovascular on US. Biopsy demonstrated histologic findings of subacute th...
Background: Fluorodeoxyglucose Positron Emission Tomography/Computed Tomography (FDG-PET/CT) functional imaging has shown to be an invaluable non-invasive, diagnostic method, enhancing the accuracy in presenting of Non-Small Cell Lung Cancer (NSCLC). The purpose this research was evaluate role maximum standardized uptake value (SUV max) PET-CT staging and follow-up operable non-operable patient...
BACKGROUND To validate a gradient-based segmentation method for gross tumor volume(GTV) delineation on (8)F-fluorothymidine (FLT)positron emission tomography (PET)/ computer tomography (CT) in esophageal squamous cell cancer through pathologic specimen, in comparison with standardized uptake values (SUV) threshold-based methods and CT. The corresponding impact of this GTV delineation method on ...
OBJECTIVES Abdominal aortic aneurysms (AAAs) are associated with an inflammatory cell infiltrate and enzymatic degradation of the vessel wall. The aim of this study was to detect increased metabolic activity in the wall of the AAA with 18F-fluorodeoxyglucose ((18)F-FDG), mediated by glucose transporter protein (GLUTs), using a dedicated hybrid PET/64-detector CT. DESIGN, METHOD AND MATERIALS: 1...
BACKGROUND The prognostic significance of volume-based metabolic parameters measured by (18)F-fluorodeoxyglucose positron emission tomography/CT ((18) F-FDG PET/CT) is not established. We evaluated the prognostic value of metabolic parameters in patients with squamous cell carcinoma (SCC) of the tonsil. METHODS We enrolled a total of 69 patients with SCC of the tonsil who underwent pretreatme...
BACKGROUND External beam radiotherapy (EBRT) is the treatment of choice for irresectable meningioma. Due to the strong expression of somatostatin receptors, peptide receptor radionuclide therapy (PRRT) has been used in advanced cases. We assessed the feasibility and tolerability of a combination of both treatment modalities in advanced symptomatic meningioma. METHODS 10 patients with irresect...
Selective CDK4/6 inhibition with tumor responses by PD0332991 in patients with mantle cell lymphoma.
Mantle cell lymphoma (MCL) carries an unfavorable prognosis and requires new treatment strategies. The associated t(11:14) translocation results in enhanced cyclin D1 expression and cyclin D1-dependent kinase activity to promote cell-cycle progression. A pharmacodynamic study of the selective CDK4/6 inhibitor PD0332991 was conducted in 17 patients with relapsed disease, using 2-deoxy-2-[(18)F]f...
