Induction of Complete Haematological Remission After Monotherapy with AntLCD20 Monoclonal Antibody (RITUXIMAB) in a Patient with Alkylating Agent Resistant Waldenstrom's Macroglobulinaemia

Abstract
Response of Waldenström's macroglobulinaemia to chemotherapy with alkylating agents is usually only transient. We report a case with marked bone marrow involvement and resistance to chemotherapy with alkylating agents. The patient was red cell and platelet transfusion dependent. Three weeks after rituximab-monotherapy, he achieved a complete haematological remission which is continuing 6 months after the end of therapy. Our case demonstrates that treatment with the unconjugated anti-CD20-monoclonal antibody (rituximab) may be a new powerful tool for a better treatment of Waldenström's macroglobulinaemia.
