Abstract

OBJECTIVE: The aim of the study was to investigate the effect of chemotherapy treatment with ABVD on brain glucose metabolism in patients with Hodgkin's disease (HD). METHODS: A total of 49 patients (23 men, 26 women; mean age 32±9 years) diagnosed with HD were included in the study. All of them underwent a baseline (PET0) and an interim (PET2) 2-deoxy-2-[F]fluoro-D-glucose (18F-FDG) PET/computed tomography (CT) brain scan. All patients were treated after PET0 with two cycles of ABVD consisting of doxorubicin (adriamycin), bleomycin, vinblastine, and dacarbazine for 2 months. Thirty-five patients were evaluated further 15±6 days after four additional cycles (PET6). Differences in brain 18F-FDG uptake were analyzed by statistical parametric mapping (SPM2). RESULTS: Compared with PET0, PET2 showed a significantly higher metabolic activity in the right angular gyrus (Brodmann area 39) and a significant metabolic reduction in Brodmann areas 10, 11, and 32 bilaterally. All these changes disappeared at PET6. CONCLUSION: Our results support the conclusion of a very limited impact of ABVD chemotherapy on brain metabolism in patients with HD.
