Phase II study of MOPLACE chemotherapy for patients with previously treated Hodgkin's disease: a CALGB study.
To further evaluate possible non-cross-resistant regimens in Hodgkin's disease, a phase II trial utilizing antimetabolites and etoposide was initiated by the Cancer and Leukemia Group B (CALGB). Etoposide was included because of its known efficacy in relapsed Hodgkin's disease and to evaluate for synergy with an alkylating agent and vincristine. Cytosine arabinoside and methotrexate were included to evaluate their effectiveness in rapidly growing resistant disease. Forty-two patients with previously treated Hodgkin's disease were entered, of which 37 are evaluable for response and toxicity. All patients had at least 2 prior regimens of chemotherapy and 59% had additional radiation therapy. Complete and partial response was observed in 61%; there were 32% complete responders. Duration of complete response was a median of 8 months (range 2-28+ months). Duration of partial response was 7 months (range 1-17 months). Three patients remain in complete remission at 19, 19, and 28 months. Major toxicity was hematologic with severe or life-threatening toxicity in 54%. There was one patient with a fatal infection. Non-hematologic toxicity, save for nausea and vomiting, was mild and uncommon. There were two fatal and one severe pulmonary toxicities reported in patients who had previous exposure to bleomycin and mediastinal radiation. Three had interstitial pneumonitis and one pulmonary emboli. The interstitial pneumonitis was thought to be drug related. Survival of the entire group is estimated at 61% at 12 months. We conclude that MOPLACE is an effective regimen with an appreciable complete response rate in this heavily pretreated group of patients. Hematologic and pulmonary toxicities are severe and may necessitate dose modifications. The use of etoposide containing combinations requires further study as primary therapy in untreated patients.
