Abstract

Therapy of lymphoblastic lymphoma (LL) has evolved with use of chemotherapy regimens modeled after those for acute lymphocytic leukemia (ALL). We treated 33 patients with LL with the intensive chemotherapy regimens hyper-CVAD (fractionated cyclophosphamide, vincristine, Adriamycin, and dexamethasone) or modified hyper-CVAD used for ALL at our institution. Induction consolidation was administered with 8 or 9 alternating cycles of chemotherapy over 5 to 6 months with intrathecal chemotherapy prophylaxis, followed by maintenance therapy. Consolidative radiation therapy was given to patients with mediastinal disease at presentation. No consolidation with autologous or allogeneic stem cell transplantation was performed. At diagnosis, 80% were T-cell immunophenotype, 70% were stages III to IV, 70% had mediastinal involvement, and 9% had central nervous system (CNS) disease. Of the patients, 30 (91%) achieved complete remission, and 3 (9%) achieved partial response. Within a median of 13 months, 10 patients (30%) relapsed or progressed. Estimates for 3-year progression-free and overall survival for the 33 patients were 66% and 70%, respectively. Estimates for the patients with known T-cell immunophenotype were 62% and 67%, respectively. No parameters (eg, age, stage, serum lactate dehydrogenase [LDH], beta(2) microglobulin) appeared to influence outcome except for CNS disease at presentation. Modification of the hyper-CVAD regimen with anthracycline intensification did not improve outcome. Other modifications of the program could include incorporation of monoclonal antibodies and/or nucleoside analogs, particularly for slow responders or those with residual mediastinal disease.
