PURPOSE To evaluate the predictive value of the early response of (18)F-flurodeoxyglucose positron emission tomography (FDG PET) during concurrent chemoradiotherapy (CCRT) for locally advanced non-small cell lung cancer (NSCLC). MATERIALS AND METHODS FDG PET was performed before and during CCRT for 13 NSCLC patients. Maximum standardized uptake value (SUVmax), mean standardized uptake value (...

Objective We aimed to investigate the metabolic characteristics of Solid pseudopapillary neoplasms (SPNs) in relation signal intensities on 18F-FDG PET scans. Summary Background Data SPNs of the pancreas commonly show high uptake of 18F-FDG. However, the metabolic characteristics underlying the high 18F-FDG uptake in SPNs are not well characterized. Materials and Methods mRNA expressions fo...

conclusions consumption of ole after tumor transplantation reduced the tumor growth. on the other hand, owing to its highly-packed polyphenols, catalase and superoxide dismutase activities in tumor tissue were increased. results treatment with 150 and 225 mg/kg/day of ole reduced the tumor volume and weight (p < 0.05) compared to the first group significantly. it also increased the cat activity...

OBJECTIVES The aim of this study was to evaluate the prognostic value of volume-based metabolic parameters measured by (18)F-fluorodeoxyglucose positron emission tomography ((18)F-FDG PET) in patients with nasopharyngeal carcinoma (NPC). METHODS Forty-four NPC patients who underwent (18)F-FDG PET/CT for initial staging work-up before concurrent chemoradiotherapy (CCRT) were retrospectively ev...

This study was to investigate the clinical outcomes between radiation dose and pretreatment metabolic tumor volume (MTV) in patients with head and neck cancer treated with definitive chemoradiotherapy.Thirty-four patients received pretreatment F-fluorodeoxyglucose (F-FDG) positron emission tomography-computed tomography (PET/CT) were recruited for this study. The CT-based volume (gross tumor vo...

Introduction: Circulating tumor DNA (ctDNA) derives from cell-free (cfDNA) and has been described as a diagnostic prognostic test in diffuse large B cell lymphoma (DLBCL). Its quantification may be used surrogate of burden. Besides, total metabolic volume (TMTV) measured by PET/CT can quantify Methods: We followed prospectively 18 patients with DLBCL collected cfDNA before treatment 2 months af...
