Abstract

Twenty‐one patients with referactory myeloma (10 primary resistant and 11 relapsed resistant) were treated with a combination of high dose methyl prednisolone and recombinant interferon alpha2b (IFN‐α2b). This treatment included three megaunits/m^2^ of IFN‐α2b three times a week for 12 weeks, plus 5‐day pulsed high dose methyl prednisolone every 3 weeks for two courses. A partial response (more than 50 per cent reduction in paraprotein) was observed in six patients; two of these had a greater than 75 per cent reduction in paraprotein, and evaluation of bone marrow showed <5 per cent plasma cells. A minimal response (more than 25 per cent reduction in paraprotein) was seen in four patients, giving an overall objective response rate of 10/21 (48 per cent). Subjective response, in terms of subsidence of pain and improvement of performance status, was seen in all patients who had adequate therapy.

The protocol was generally well tolerated with minimal side‐effects. There were 4/21 (19 per cent) treatment‐related deaths which, though considerable, was anticipated in such a study population. The excellent subjective response seen supplements the objective response observed, and suggests a potential role for the combination of methyl prednisolone and IFN‐α2b in refractory myeloma.
