Combination therapy of M2-protocol and interferon-alpha as remission induction in refractory multiple myeloma.
A successful induction of remission in two patients with resistant multiple myeloma using a new combination therapy of modified M-2 protocol and interferon-alpha (IFN-alpha) is described. The first case was a 32-year-old man with K type urinary Bence-Jones protein who became resistant after treatment with melphalan and prednisone (MP protocol). IFN-alpha alone had a marginal response. The modified M-2 protocol proved insufficient. Therefore, IFN-alpha was administered in the interval of M-2 protocol. This combination therapy showed remarkable responses. The second case was a 59-year-old woman with advanced IgA myeloma who was treated with M-2 protocol and became resistant. IFN-alpha alone resulted in a slight response. After addition of IFN-alpha to the modified M-2 protocol, a rapid reduction in the level of serum IgA was found and clinical symptoms including bone pain, anaemia and so on were dramatically improved. No infection and/or intolerable side effects were observed in either case. This combination treatment appears worthy to try in cases of resistant or relapsing myeloma patients.
