Early chemotherapy intensification with BEACOPP in advanced-stage Hodgkin lymphoma patients with a interim-PET positive after two ABVD courses.

UNLABELLED

Interim 2-[18F]Fluoro-2-deoxy-D-glucose Positron Emission Tomography performed after two chemotherapy cycles (PET-2) is the most reliable predictor of treatment outcome in ABVD-treated Hodgkin Lymphoma (HL) patients. We retrospectively analysed the treatment outcome of a therapeutic strategy based on PET-2 results: positive patients switched to BEACOPP, while negative patients continued with ABVD. Between January 2006 and December 2007, 219 newly diagnosed HL patients admitted to nine centres were enrolled; 54 patients, unfit to receive this treatment were excluded from the analysis. PET-2 scans were reviewed by a central panel of nuclear medicine experts, according to the Deauville score (Meignan, 2009). After a median follow up of 34 months (12-52) the 2-year failure free survival (FFS) and overall survival for the entire cohort of 165 patients were 88% and 98%; the FFS was 65% for PET-2 positive and 92% for PET-2 negative patients. For 154 patients in which treatment was correctly given according to PET-2 review, the 2-year FFS was 91%: 62% for PET-2 positive and 95% for PET-2 negative patients.

CONCLUSIONS

this strategy, with BEACOPP intensification only in PET-2 positive patients, showed better results than ABVD-treated historic controls, sparing BEACOPP toxicity to the majority of patients.
