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

Relapsed aggressive lymphoma (DLBCL)

Patients candidates to HDT/ASCT (<60-65y)

Accepted strategy

Short salvage chemotherapy

Evaluation of response

HDT/ASCT

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?

TAKE HOME MESSAGES

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

TAKE HOME MESSAGES

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
