In a mouse model of human lung cancer, intratumoral distribution between 3'-deoxy-3'-[18F] fluorothymidine (18F-FLT) and [18F] fluorodeoxyglucose (18F-FDG) was mutually exclusive. 18F-FLT primarily accumulated in proliferating cancer cells, whereas 18F-FDG accumulated in hypoxic cancer cells. The aim of the present study was to evaluate these preclinical findings in patients with lung cancer. A...
Development of the positron emission tomography (PET) diagnostic radiopharmaceutical (18F) fluoro-2-deoxy-D-glucose (18F-FDG) subsequently facilitated the discovery and clinical evaluation of several new tracers as imaging markers for cancer. While 18F-FDG is a widely employed marker for enhanced intracellular glycolysis and metabolic function, one of the newer tracers, (18F)-3’-fluoro-3’ deoxy...
AIM 3'-deoxy-3'-[¹⁸F]fluorothymidine ([18F]FLT) is a tracer used to assess cell proliferation in vivo. The aim of the study was to use [18F]FLT positron emission tomography (PET) to study non-invasively early anti-proliferative effects of the experimental chemotherapeutic agent TP202377 in both sensitive and resistant tumors. METHODS Xenografts in mice from 3 human cancer cell lines were used...
BACKGROUND Pathogenic autoantibodies targeting the recently identified leucine rich glioma inactivated 1 protein and the subunit 1 of the N-methyl-D-aspartate receptor induce autoimmune encephalitis. A comparison of brain metabolic patterns in 18F-fluoro-2-deoxy-d-glucose positron emission tomography of anti-leucine rich glioma inactivated 1 protein and anti-N-methyl-D-aspartate receptor enceph...
Fluorothymidine is a thymidine analog labeled with fluorine-18 fluorothymidine for positron emission tomography (18F-FLT-PET) imaging. Thymidine is a nucleic acid that is used to build DNA. Fluorine-18 fluorothymidine (18F-FLT) utilizes the same metabolic pathway as does thymidine but has a very low incidence of being incorporated into the DNA (<1%). 18F-FLT-PET could have a role in the evaluat...
OBJECTIVES The study objective was to assess the diagnostic performance of positron emission tomography (PET) for gliomas using the novel tracer 18F-fluciclovine (anti-[18F]FACBC) and to evaluate the safety of this tracer in patients with clinically suspected gliomas. METHODS Anti-[18F]FACBC was administered to 40 patients with clinically suspected high- or low-grade gliomas, followed by PET ...
Positron emission tomography (PET) with 18F-fluorodeoxyglucose (FDG) is a diagnostic tool to evaluate metabolic activity by measuring accumulation of FDG, an analogue of glucose, and has been widely used for detecting small tumors, monitoring treatment response and predicting patients' prognosis in a variety of cancers. However, the molecular mechanism of FDG accumulation into tumors remains to...
We investigated whether 18F-fluorothymidine-positron-emission tomography/computed tomography (18F-FLT-PET/CT) is useful for the evaluation of the very early response to anti-epidermal growth factor receptor (EGFR) antibody cetuximab therapy in human lung cancer xenografts. A human tumor xenograft model was established with a human non-small cell lung cancer cell line. The mice were randomly ass...
BACKGROUND The detection of solitary pulmonary nodules (SPNs) that may potentially develop into a malignant lesion is essential for early clinical interventions. However, grading classification based on computed tomography (CT) imaging results remains a significant challenge. The 2-[18F]-fluoro-2-deoxy-D-glucose (18F-FDG) positron emission tomography (PET)/CT imaging produces both false-positiv...
Objective: Antiangiogenesis therapy (AAT) has provided substantial benefits regarding improved outcomes and survival for suitable patients in clinical settings. Therefore, the early definition of therapeutic effects is urgently needed to guide cancer AAT. We aimed to optimize the early response monitoring and prediction of AAT efficacy, as indicated by the multi-targeted anti-angiogenic drug su...
