Description:
Background: FDG-PET scan performed early during chemotherapy (CT) is a powerful prognostic tool in lymphoma management. This study aimed to compare the predictive value on treatment outcome of the International Prognostic Score (IPS) with that of FDG-PET scan performed after two courses of standard CT in untreated advanced stage (AS) HL patients. Patients: From December 2001, 202 new AS HL patients were consecutively admitted to 11 Italian and 3 Danish hematological centers, on behalf of Intergruppo Italiano Linfomi and Danish Lymphoma Cooperative Group. The mean age was 35.5 years (14–79), the male/female ratio 105/97; AS (IIB–IVB) was present in 153, and unfavorable stage IIA (〉 3 nodal sites involved or sub-diaphragmatic presentation or bulky disease or ESR 〉 40) in 49. Bulky and extranodal disease was recorded in 71 and 58 patients, respectively. All patients had FDG-PET at baseline (PET-0) and after 2 courses of CT (PET-2). 192 patients were treated with ABVD, 8 with ABVD-like CT, 2 with BEACOPP. 102 patients received consolidation radiotherapy after CT. All patients were given the therapy programmed at baseline, except in case of overt progression. Results: The mean time from the diagnosis to latest follow-up was 796 days (range 91–1716). 164 patients attained CR while 38 were chemoresistant: 34 showed disease progression during CT and 4 showed early relapse (within 6 months) after CR entry: (+28 – +178 days). 4 out of the 164 pts attaining CR relapsed later than 6 months. In univariate analyses, both PET-2 (p
