[Clinical study on the effect of human lymphoblastoid interferon in multiple myeloma]

Ten patients with multiple myeloma were treated with human lymphoblastoid interferon (HLBI). The dosages used were 3 X 10(6) IU to 6 X 10(6) IU of HLBI intramuscularly daily. Out of eight evaluable patients, one partial remission and 3 minor response were observed. More than half patients experienced fever exceeding 38 degrees C and mild myelosuppression. Other toxic effects consisted of anorexia, malaise, liver dysfunction and skin rash. On the basis of our preliminary study, we conclude that HLBI is an effective agent against multiple myeloma.
