The use of anthracyclines in adult acute lymphoblastic leukemia.

A critical review of the role of anthracyclines in the management of adult patients with acute lymphoblastic leukemia was performed to define current indications for their use. Major pertinent clinical series were reviewed with reference to anthracycline type, cumulative dosage and dose intensity, and administration schedule during both induction therapy and postremission consolidation, comparing results, whenever possible, with non-anthracycline treatment groups. A subgroup analysis was performed to evidentiate disease subtypes likely associated with a favorable outcome to anthracycline treatment. The results indicated that anthracyclines may still play a primary role in this setting. In particular, anthracyclines should be used at full therapeutic doses, especially during induction and early consolidation; idarubicin could be a better choice than daunorubicin or adriamycin; finally, an early brief intensive treatment with anthracyclines may provide an excellent probability of long-term disease-free survival in CD10+ t(9;22)-negative B-precursor adult ALL, obviating the need for prolonged maintenance or late reinduction therapy.

Therapeutic impact of adult-type acute lymphoblastic leukemia regimens in B-cell/L3 acute leukemia and advanced-stage Burkitt's lymphoma.

BACKGROUND: Adult B/L3-ALL is a rare disease subset characterized by an aggressive clinical course and a poor response to conventional adult ALL-type chemotherapy. Recent data from the GMALL Group showed that prognosis can be improved with an innovative treatment regimen. In the current retrospective survey we focus on therapeutic results obtained at our Institutions during a 15-year period with ALL-type regimens in 34 adults with either B/L3-ALL or advanced-stage Burkitt's lymphoma. METHODS: Five successive ALL treatment programs were developed. They included a homogeneous induction phase with early intrathecal chemoprophylaxis, multidrug postremission consolidation followed by cranial irradiation (4 trials), high-dose chemotherapy plus autografting (2 trials), late consolidation (2 trials), and variable-length maintenance (4 trials). Early response and prolonged disease-free survival rates were analyzed according to selected clinical and therapeutic variables. RESULTS: Overall, a complete remission was achieved in 62%, with a median duration of 1.6 years and a 10-year remission rate of 49%. A diagnosis of B/L3-ALL (p = 0.007), the use of idarubicin instead of adriamycin during induction (p = 0.018), a serum creatinine < 1.6 mg/dL, and an uninvolved central nervous system were associated with higher response rates. As regards long-term disease-free survival, results were significantly better in patients with < 1 x 10(9)/L L3/blast cells in the peripheral blood (p = 0.0029) and/or aged < 50 years (p = 0.04), and in those consolidated with the most recent rotational high-dose plus peripheral blood stem cell autotransplant regimen. CONCLUSIONS: According to the results presented, ALL-like regimens may still represent a worthwhile therapeutic choice. The use of idarubicin during induction, the prognostic subclassification of patients, a careful control of dysmetabolic complications, the selection of the proper chemo-radioprevention for meningeal disease and perhaps the introduction of high-dose chemotherapy supported by autologous stem cell rescue appear to be the mainstay of further improvements.
