We present our results of a MACOP-B regimen in a series of 46 patients with high-grade NHL. The complete remission rate was 74% for patients with advanced stage disease. The excellent tolerance allowed this regimen to be given on an outpatient basis in the majority of cases. The median follow-up for the living patients is 28 months. Although some patients received additional treatment that could influence the results, the predicted DFS (disease-free survival) at 45 months of 57% compares favorably with the best results published so far with more toxic regimens.
