On February 10th, the merging of the GELA and the Goelams
lymphoma groups resulted in the birth of the new group Lysa.

Rituximab effect
• Major breakthrough with the combination of
rituximab with chemotherapy
• R-CHOP became the standard for the majority
of patients
• But some patients continue to not respond to
or relapse after R-CHOP

Questions

1.- Which optimal salvage chemotherapy regimen?

2.- Will rituximab combined with salvage chemotherapy be effective if previously
used first-line?

3.- Is rituximab useful as maintenance therapy after HDT/ASCT?

based on CORAL study
 A new profile of relapses and refractory patients after
rituximab is seen
 Prognostic factors affecting response and survival
are:
• relapse < 12 months
• secondary IPI>1
• prior rituximab exposure
 When rituximab has been used during first-line
therapy: optimal salvage combination remains to be
determined? New drugs mandatory

 Molecular characteristics are “similar” at diagnosis and
relapse.
• Differential efficacy of non-based anthracycline chemotherapy
within molecular subtypes of DLBCL
• MYC rearrangement is associated with a bad prognosis,
independently from the type or treatment or other biological
prognostic classification
 Importance of realizing molecular characterization in DLBCL
for a rational development of treatment.
 Clinical prognostic factors remain very important

 This prospective multicenter trial suggest that
R - GemOx regimen is a safe outpatient salvage
regimen.
 The response rate of 60%, after 4 cycles, observed
across a wide age range of patients appears similar to
the response rate obtained with other salvage regimens
(RICE, R-DHAP…) and appears less toxic.
 The familiarity of practicing oncologists with the
GemOx combination for other malignancies will allow it
to be largely applied to lymphoma.
A new profile of patients relapsing less than one
year after the end of last treatment and previously
treated xith rituximab come out from this trial
(median PFS: 2 months), and will help the design
of future studies with new drugs
This regimen could be considered as a platform
for new combinations
