The purpose of this study was to determine the 18F-FDG avidity of MALT lymphoma and the additional utility of 18F-FDG PET/CT in MALT lymphoma staging. Pretreatment 18F-FDG PET/CT scans of 222 patients with 227 MALT lymphoma lesions were retrospectively analyzed. 18F-FDG avidity of lesions was noted in 28%. The proportion was lower for gastric MALT lymphomas(More)
OBJECTIVES The aim of the study was to evaluate the usefulness of the antithyroglobulin autoantibody (TgAb) value at 6-12 months after remnant ablation in predicting recurrence in differentiated thyroid carcinoma patients who had undetectable thyroglobulin (Tg) values. The change in TgAb concentration measured between the time of remnant ablation (TgAb1)(More)
PURPOSE To evaluate the usefulness of 3'-deoxy-3'-[18F]fluorothymidine (FLT)-positron emission tomography (PET) for predicting response and patient outcome of gefitinib therapy in patients with adenocarcinoma of the lung. EXPERIMENTAL DESIGN Nonsmokers with advanced or recurrent adenocarcinoma of the lung were eligible. FLT-PET images of the thorax were(More)
The antigenic characterizations and serological reactions of human liver flukes, Clonorchis sinensis and Opisthorchis viverrini, were analyzed by immunoblot. The antigenic profiles of the crude extract of Clonorchis contained major proteins of 8, 26-28, 34-37, 43, and 70 kDa, and those of Opisthorchis 34-37, 43, 70, and 100 kDa. Of these, the 8, 26-28 and(More)
OBJECTIVE The purpose of this study was to investigate the diagnostic performance of postoperative fluorine-18 fluoro-2-deoxy-D-glucose ((18)F-FDG) positron emission tomography/computed tomography (PET/CT) as a surveillance modality for advanced gastric cancer patients who were asymptomatic and negative by conventional follow-up. METHODS We(More)
PURPOSE To investigate the feasibility of fluorine-18-labeled fluoromisonidazole positron emission tomography/computed tomography ((18)F-FMISO PET/CT)-guided intensity-modulated radiotherapy (IMRT) in dose escalation to attack the hypoxic volume of a tumor mass without increasing the normal tissue dose in head and neck cancer patients. MATERIALS AND(More)
UNLABELLED (4S)-4-(3-(18)F-fluoropropyl)-l-glutamate ((18)F-FSPG, or BAY 94-9392) is a new tracer to assess system x(C)(¯) transporter activity with PET. The aim of this study was to explore the tumor detection rate of (18)F-FSPG, compared with that of (18)F-FDG, in patients with hepatocellular carcinoma (HCC). METHODS Preclinically, in vivo HCC models of(More)
CONTEXT Some patients have elevated stimulated thyroglobulin (sTg) concentrations after reoperation for locoregionally recurrent/persistent papillary thyroid cancer (PTC). Little is known, however, about the efficacy of adjuvant radioactive iodine (RAI) therapy in these patients. OBJECTIVE The objective of the study was to evaluate the efficacy of(More)
PURPOSE The aim of this study was to determine whether (18)F-fluorothymidine (FLT) PET is feasible for the early prediction of tumor response to induction chemotherapy followed by concurrent chemoradiotherapy in patients with esophageal cancer. METHODS This study was prospectively performed as a collateral study of "randomized phase II study of(More)
PURPOSE This study was performed to assess the usefulness of (18)F-fluorodeoxyglucose ((18)F-FDG) positron emission tomography (PET) or PET/computed tomography (CT) for distinguishing thymic epithelial tumors according to World Health Organization (WHO) classifications. METHODS We analyzed a total of 45 patients (range, 29-75 years of age; mean, 55 years)(More)
