Abstract
Between Nov. 1985 and Nov. 1988, sixty-three patients with high grade malignant (hg) and intermediate grade malignant (img) Non Hodgkin's Lymphoma (NHL) were treated with MACOP-B (methotrexate, doborubicin, cyclophosphamide, vincristine, prednison and bleomycin). Thirty-seven patients received MACOP-B as an upfront treatment modality, whereas twenty-six patients had relapsed disease and received MACOP-B as a salvage protocol. Four weeks after termination of therapy, 75% of patients with de novo NHL and 72% of the patients with relapsed NHL were in complete remission (CR). In the group of newly diagnosed NHL, 22% achieved partial remission (PR) and 3% no change (NC), whereas in the group with relapsed disease 14% had PR and 14% had progressive disease (PD). At a medium follow-up of 12 months (range 1 month to 33 months), 74% of patients with de novo NHL continued to be in CR whereas the continuous CR rate in patients with relapsed disease was 35%. Overall survival after 30 months of observation for the patient group with de novo NHL was 75% and 40% for patients with relapsed NHL. The mean duration for completion of the projected 12 chemotherapy cycles, given in weekly intervals, was 12.9 and 13.5 weeks in upfront or salvage therapy, respectively. With low incidence of major toxicities, application of drugs on an outpatient basis, and high efficacy, MACOP-B shows substantial advantges for therapy of de novo and relapsed NHL.
