[Interferon therapy in multiple myeloma].

Natural leukocyte interferon and recombinant interferon alpha-2 have effected remission rates between 10 and 20% in the treatment of multiple myeloma. Response rates have been higher in untreated patients than in relapsing or primarily refractory cases. Patients with slowly proliferating tumors, early tumor stage or IgA-monoclonal protein seem to show increased sensibility to interferon as compared to patients without those characteristics.
