Abstract

The use of 18F-FDG-PET/CT has changed the management of patients with lymphoma for the last two decades. This technique improves initial staging of the disease, making a prognostic approach and appropriate treatment planning, as well as monitoring therapy response of lymphoma. However, there are still controversial issues in medical literature that impact on daily clinical practice. This comprehensive literature review summarizes the current information regarding the potential use of 18F-FDG-PET/CT in patients with lymphoma, highlighting the main applications and the current dilemmas for the nuclear medicine physicians at the time of the evaluation of these studies, trying to standardize criteria for its assessment, particularly in restaging and therapy monitoring.

Resumen

El uso del 18F-FDG-PET/TC ha introducido cambios relevantes en el manejo de los pacientes con linfoma en las últimas dos décadas. Esta técnica de imagen funcional permite mejorar la estadificación inicial de la enfermedad, realizar una aproximación pronóstica y planificar un tratamiento adecuado, monitorizar la respuesta a las terapias instauradas y hacer un seguimiento para el diagnóstico de recidiva y reestadificación del linfoma. Sin embargo, aún existen controversias sobre el tema en la literatura médica que repercuten en la práctica diaria. Esta profunda revisión bibliográfica resume la información actual sobre el uso potencial de 18F-FDG-PET/TC en pacientes con linfoma, destacando sus principales aplicaciones y los dilemas que se presentan al evaluar este tipo de estudios, intentando estandarizar criterios para su valoración, particularmente en la reestadificación y monitorización de la terapia.
