Secondary Hodgkin's disease in childhood acute lymphoblastic leukemia.
Improved survival in childhood acute lymphoblastic leukemia has led to the occurrence of second malignancies in these patients. Hodgkin's disease is very rare as a second malignancy. We report three patients with acute lymphoblastic leukemia in remission who developed Hodgkin's disease. Although all had received low-dose irradiation, none received alkylating agents as part of their chemotherapy. Review of our cases and of 11 reported in the literature revealed unique aspects of this association. There was a short median interval of 19 months to the development of the second malignancy. Over one-third of the patients had uncommon sites of involvement (lung, tonsil, small bowel). The distribution of histologic subtypes was unusual, as 5 of 14 cases had lymphocyte depletion or unclassifiable Hodgkin's disease. The results of therapy were excellent. Our three patients are alive, with both malignancies in continuing remission. Two patients are off all therapy for 4 and 6 years, respectively. The third remains on antileukemic treatment. Secondary Hodgkin's disease in childhood acute lymphoblastic leukemia does not appear to have a poor prognosis and long-term survival and possible cure of both diseases may be achieved.
