Has any one out there survived mantle cell lymphoma?

Yes. Controlis quite high, but it needs aggressive treatment.
Definitely Yes. Mantle cell lymphoma responds very well to conventional chemotherapy but has a propensity to relapse. Incorporation of maintenance treatment or autotransplant has prolonged remissions and survival but a stem cell transplant using a matched sibling or unrelated donor can lead to a cure albeit with potential complications from graft-versus-host disease.
