- The objective of the LNH 93-1 study was to compare, in patients aged from 18 to 60 years 3 cycles of CHOP followed by radiotherapy with chemotherapy alone consisting in 3 cycles of ACVBP. The ACVBP regimen includes a more intensive induction followed by a sequential consolidation. With a median follow up of 55 months, the results have shown a superiority of the ACVBP arm for both the 5 year event free (83% vs. 74%, p = 0.004) and overall survival (89% vs. 80%, p = 0.02).
