|Abstract:||The long-term results of a therapeutic regimen for adult acute lymphoblastic leukemia (ALL) have been analysed with the main purpose to evaluate the impact of Daunorubicin (DNM) dosage given during the induction. The files of 86 consecutive adult ALL patients treated in our institution between 1974 and 1988 were reviewed. They received the same induction regimen based on Vincristine, DNM and Prednisone, consolidation with L-Asparaginase, central nervous system prophylaxis, and 3-year maintenance with 6-mercaptopurine and Methotrexate with periodic cycles of reinduction. We analysed the overall and disease-free survival (DFS) in relation to various prognostic factors, focusing on the dosage of DNM actually received during the induction period. Complete remission (CR) was achieved in 68 (79%) patients and the overall DFS was of 32 months (median follow-up 37 months); 22 patients (25.6%) are off-therapy and disease-free. The actual dosage of DNM received during induction turned out to be an independent DFS prognostic factor. In fact, patients who received more or less than 175 mg/sqm in induction had a median DFS of 44 and 12 months, respectively (p = 0.05). The plateau of DFS in the two groups was 44% and 21%, respectively. Similar data were found analyzing the dose-intensity (mg/sqm/week) of DNM given in induction. Our data suggest that the actual dosage of DNM given in induction plays a role in the long term DFS of adult ALL.|
