Fluorine-18 fluorodeoxyglucose positron emission tomography, gallium-67 scintigraphy, and conventional staging for Hodgkin's disease and non-Hodgkin's lymphoma

Abstract

PURPOSE: To compare fluorine-18 fluorodeoxyglucose positron emission tomography (PET) and gallium scanning with each other and with conventional staging, for patients with Hodgkin's disease or non-Hodgkin's lymphoma. SUBJECTS AND METHODS: Fifty patients had PET, gallium scanning, and conventional staging of newly diagnosed or progressive Hodgkin's disease or non-Hodgkin's lymphoma. Disease sites, stage, and treatment plans were assessed retrospectively. RESULTS: Positron emission tomography and gallium scanning each upstaged 14% of patients (n = 7). Management was altered by PET in 9 cases (18%) and by gallium scanning in 7 (14%, P = 0.6). Disease was evident in 117 sites in 42 patients. The..
