Abstract

BACKGROUND:

There is no consensual first-line chemotherapy for elderly patients with mantle cell lymphoma (MCL). The GOELAMS (Groupe Ouest-Est des Leucémies Aiguës et Maladies du Sang) group previously developed the (R)VAD+C regimen (rituximab, vincristine, doxorubicin, dexamethasone and chlorambucil), which appeared as efficient as R-CHOP (rituximab, cyclophosphamide, doxorubicine, vincristine, prednisone) while less toxic. Based on this protocol, we now added bortezomib (RiPAD+C: rituximab, bortezomib, doxorubicin, dexamethasone and chlorambucil) given its efficacy in relapsed/refractory MCL patients. The goal of the current phase II trial was to evaluate the feasibility and efficacy of the RiPAD+C regimen as frontline therapy for elderly patients with MCL.

PATIENTS AND METHODS:

Patients between 65 and 80 years of age with newly diagnosed MCL received up to six cycles of RiPAD+C.

RESULTS:

Thirty-nine patients were enrolled. Median age was 72 years (65-80). After four cycles of RiPAD+C, the overall response rate was 79%, including 51% complete responses (CRs). After six cycles, CR rate increased up to 59%. After a 27-month follow-up, median progression-free survival (PFS) is 26 months and median overall survival has not been reached. Four patients (10%) discontinued the treatment because of a severe toxicity and seven patients (18%) experienced grade 3 neurotoxicity.

CONCLUSION:

The bortezomib-containing RiPAD+C regimen results in high CR rates and prolonged PFS with predictable and manageable toxic effects in elderly patients with MCL.
