Brief Summary
This is a multicenter, phase 2, randomized trial to compare rituximab maintenance with observation after rituximab and lenalidomide (R2) induction therapy in patients with previously untreated marginal zone lymphoma. Patients who achieve complete response or partial response after R2 induction will be randomized to receive rituximab maintenance or observation.

Study Arms (2)
Rituximab
EXPERIMENTALPatients will receive induction therapy with rituximab and lenalidomide. If CR or PR: maintenance therapy with rituximab every 8 weeks for 2 years.
Observation
ACTIVE COMPARATORPatients will receive induction therapy with rituximab and lenalidomide. If CR or PR: observation.
Interventions
Patients will receive R2 induction therapy consisting of rituximab and lenalidomide. Patients who achieve complete response or partial response after induction will receive rituximab maintenance every 8 weeks for up to 2 years.
Patients will receive R2 induction therapy consisting of rituximab and lenalidomide. Patients who achieve complete response or partial response after induction will undergo observation without maintenance anti-lymphoma therapy.
