Ten previously untreated patients with stages I and II Hodgkin's disease were treated with MOPP chemotherapy alone. Eight of nine evaluable patients went into complete remission (CR). Six remained in CR on the average 82.7 months after induction. Two patients relapsed early and died more than 5 years after entering the study. The patient in whom CR was not achieved died as well. The estimated 10-year survival rate is 51%. This experience adds to the very small number of reports that have appeared describing the results of treatment of patients with early stage Hodgkin's disease with MOPP alone.
