Autologous bone marrow transplantation for adult poor-risk lymphoblastic lymphoma in first remission.
PURPOSE Adult patients with poor-risk lymphoblastic lymphoma (LBL) treated with intensive multiagent chemotherapy (acute lymphoblastic leukemia [ALL]-like regimens) have a poor prognosis, with a disease-free long-term survival rate of less than 20%, caused by a very high relapse rate. Thus, adult patients with poor-risk LBL are candidates for alternative intensive consolidation therapy. PATIENTS AND METHODS Nine adult patients with poor-risk LBL in first remission after treatment with cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP; six patients) or ALL-like regimens (three patients), were treated with high-dose cyclophosphamide and total body irradiation (TBI) followed by nonpurged autologous bone marrow transplantation (ABMT). RESULTS Two of nine patients relapsed at 4 and 8 months, respectively, after BMT, and one patient died of acute myeloblastic leukemia (AML) 7 months after ABMT without recurrence of his lymphoma. Six patients are in unmaintained first remission with a follow-up of 12 to 113 months (median, 53 months) after transplantation. CONCLUSIONS These results suggest that intensive consolidation therapy with high-dose cyclophosphamide and TBI followed by nonpurged ABMT may improve the long-term prognosis of this disease.
