objective(s): this study aimed to evaluate the role of pretreatment suvmax and volumetric fdg positron emission tomography (pet) parameters in the differentiation between benign and malignant mediastinal tumors. in addition, we investigated whether pretreatment suvmax and volumetric fdg-pet parameters could distinguish thymomas from thymic carcinomas, and low-risk from high-risk thymomas.method...

OBJECTIVE To explore the relationships between primary tumor 18F-FDG uptake measured as the SUVmax and local extension, and nodal or distant organ metastasis in patients with NSCLC on pretreatment PET-CT. METHODS 93 patients with NSCLC who underwent 18F-FDG PET-CT scans before the treatment were included in the study. Primary tumor SUVmax was calculated; clinical stages, presence of local ext...
The aim of this study was to investigate the prognostic significance of standardized uptake value (SUV) on 18 fluorine-fluorodeoxyglucose (18F-FDG) positron emission tomography/computed tomography (PET/CT) in patients with nasopharyngeal carcinoma (NPC). Thirty-four patients who have histologically proven NPC and underwent 18F-FDG PET/CT were included in this study. After 18F-FDG PET/CT, all th...
BACKROUND We aimed to evaluate initial PET/CT features of primary tumour and locoregional metastatic lymph nodes (LNs) in breast cancer and to look for potential relationships between several parameters from PET/CT. MATERIAL/METHODS Twenty-three women (mean age; 48.66±12.23 years) with a diagnosis of primary invasive ductal carcinoma were included. They underwent PET/CT imaging for the initia...
OBJECTIVES The aim of this study is to determine the correlation of pretreatment fluorine-18 fluorodeoxyglucose uptake with clinicopathological factors and its prognostic value in patients with newly diagnosed diffuse large B-cell lymphoma (DLBCL). PATIENTS AND METHODS A cohort of 162 patients with newly diagnosed DLBCL who had undergone pretreatment PET/computed tomography was retrospectivel...
maximum standardized uptake value (SUVmax), more frequent constitutional symptoms, poorer performance status (PS), lower hemoglobin and platelets, and higher lactate dehydrogenase andb-2-microglobulin. An SUVmax ‡10 strongly correlatedwithmortality (overall survival [OS], 56.7 vs 6.9 months in patients with SUVmax <10 vs ‡10). Survival of patientswithRS andHACwas similar among patientswith SUVm...
PURPOSE To investigate the relation between PET-CT SUVmax value and prognostic factors in locally advanced breast cancer. METHODS Data of 73 patients were retrospectively analyzed. Relations between SUVmax value, clinical stage, tumor grade and breast cancer molecular subtypes were analyzed by using one-way ANOVA and x(2) tests. Correlations between age, ki-67 scores and SUVmax were evaluated...
The aim of the present study was to investigate the association between positron emission tomography (PET) parameters and peripheral inflammatory markers, and assess their prognostic value in nasopharyngeal carcinoma (NPC). A total of 121 patients with non-disseminated NPC were recruited. Pretreatment maximum standardized uptake values (SUVmax) of PET and peripheral inflammatory factors (leukoc...
PURPOSE To assess the ability of 18F-FDG PET/CT alone or combined with CA19-9 to diagnose pancreatic cancer and to analyze the correlation between maximal standardized uptake value (SUVmax) and clinical characteristics. METHODS Ninety-one patients diagnosed with pancreatic cancer using 18F-FDG PET/CT before treatment were analyzed. Definite diagnosis was by histology or cytology. The SUVmax o...
