Abstract

The authors report the use of a cyclophosphamide, hydroxydaunorubicin, vincristine, and prednisone (CHOP)-based chemotherapy regimen in treating six children with posttransplantation lymphoproliferative disorder (PTLD) that developed after solid organ transplantation.The chemotherapy regimen consisted of a 29-day induction with CHOP and then as many as 15 cycles of maintenance therapy using methotrexate and cytarabine alternating with vincristine, adriamycin, mercaptopurine, and prednisone.All patients attained remission. One patient died of sepsis while in remission. Four of the five remaining patients have been followed-up in remission for as long as 8 years without losing the graft. One of the patients experienced relapse after completing therapy and subsequently died with disease.The authors conclude that pediatric patients with PTLD after solid organ transplantation that fails conservative management can be treated successfully with CHOP-based chemotherapy.
