Evaluation of erlotinib treatment response in non-small cell lung cancer using metabolic and anatomic criteria

2016

BACKGROUND: In this paper the clinical value of PET for early prediction of tumor response to erlotinib in patients with advanced or metastatic non-small cell lung cancer (NSCLC) after failure of at least one prior chemotherapy regimen is evaluated. The aim was to compare the early metabolic treatment response using European Organization for Research and Treatment of Cancer (EORTC) 1999 recommendations and PET Response Criteria in Solid Tumors (PERCIST), and the standard treatment response using Response Evaluation Criteria in Solid Tumors (RECIST). METHODS: Twenty patients with stage IV NSCLCwere enrolled prospectively. PET/CT studies were performed before, then 48 hours, and 45 days after…

The role of 18F-FDG PET/CT in early infectious discitis: a case report after a negative MRI

2019

We present the case of a 70 years old woman with infectious discitis which was detected using Fluorine fluodeoxiglucose positron emission tomography/computed tomography (18F-FDG PET/CT), after a negative magnetic resonance imaging. A Streptococuss gallolyticus (bovis gender bacteria) grow on culture. In addition 18F-FDG PET also demonstrated infectious endocarditis which was confirmed by transesophageal echocardiography and a colonic neoplasm. Here we have highlighted the potential role of 18F-FDG PET/CT study in patients with a clinical history suggestive of infectious discitis with a negative or indifferent magnetic resonance imaging.

Utilidad del análisis de los parámetros metabólicos de la 18F-FDG PET/TC en pacientes con cáncer de mama. Valor añadido de la tomografía por emisión …

UTILIDAD DEL ANÁLISIS DE LOS PARÁMETROS METABÓLICOS DE LA 18F-FDG PET-TC EN PACIENTES CON CÁNCER DE MAMA. VALOR AÑADIDO DE LA TOMOGRAFÍA POR EMISIÓN DE POSITRONES (MAMMI-PET) La hipótesis principal es que los parámetros metabólicos obtenidos de la 18F-FDG PET/TC (SUV máx, GTL y VMT) en pacientes con cáncer de mama podrían ser útiles en la valoración pronóstica dependiendo del perfil IHQ de los tumores. Objetivos secundarios: - Correlacionar parámetros metabólicos analizados con perfiles IHQ. - Correlacionar parámetros metabólicos con características clínico-tumorales (edad, tipo y grado histológico, localización y tamaño tumoral, actividad proliferativa ki67, expresión de receptores). - Cor…
