Early Interim 2-[ 18 F]Fluoro-2-Deoxy-D-Glucose Positron Emission Tomography Is Prognostically Superior to International Prognostic Score in Advanced-Stage Hodgkin's Lymphoma: A Report From a Joint Italian-Danish Study

PURPOSE: Starting from November 2001, 260 newly diagnosed patients with Hodgkin's lymphoma (HL) were consecutively enrolled in parallel Italian and Danish prospective trials to evaluate the prognostic role of an early interim 2-[(18)F]fluoro-2-deoxy-D-glucose positron emission tomography (FDG-PET) scan and the International Prognostic Score (IPS) in advanced HL, treated with conventional ABVD (doxorubicin, bleomycin, vinblastine, and dacarbazine) therapy. PATIENTS AND METHODS: Most patients (n = 190) presented with advanced disease (stages IIB through IVB), whereas 70 presented in stage IIA with adverse prognostic factors. All but 11 patients were treated with standard ABVD therapy followed by consolidation…
