Spots Global Cancer Trial Database for A Randomized Trial Assessing the Roles of AraC in Newly Diagnosed APL Promyelocytic Leukemia (APL)

Study Description

Brief Summary: The first purpose of this randomized trial will be to compare the best treatment group of APL 93 trial (ATRA with early introduction of anthracycline-AraC chemotherapy, followed by 2 consolidation anthracycline-AraC courses and maintenance combining continuous chemotherapy and intermittent ATRA) to the same regimen, but without AraC. It is hoped that the investigational arm, with anthracycline alone chemotherapy (without AraC), will have reduced toxicity without increasing the incidence of relapse, by comparison with a classical induction/consolidation anthracycline-AraC regimen Thus : the main end point for this first randomization is relapse at 2 years secondary end points are : complete remission rate ; survival and event free survival at 2 years, and quality-adjusted survival (Q-TWiST). 2) Because patients with initial WBC counts \> 10000/mm3 (ie very high counts for APL) appear to remain at relatively high risk of relapse even with the current reference treatment, they will not be included in this trial that assesses the reduction of chemotherapy. On the contrary: i) they will all receive the standard chemotherapy (best treatment group of APL 93 trial); Thus : the main end point for this second randomization is relapse at 2 years secondary end points are : survival and event free survival at 2 years 3)Elderly patients with initial WBC ≤ 10000/m3 will receive consolidation chemotherapy without AraC during the first chemotherapy course, and reduced doses of AraC during the second and third course, followed by G-CSF.

Detailed Description: All patients will receive induction treatment with ATRA and a first chemotherapy course, followed by two consolidation chemotherapy courses and maintenance with continuous low dose chemotherapy and intermittent ATRA. Initial stratification will be based on age and WBC count. Patients aged 60 years with initial WBC 10 00 will all receive the reference AraC+ group (Group A ) (no randomization). Patients with initial WBC \> 10000/mm3 will initially all be treated according to the AraC+ group. Patients \> 60 years and with initial WBC ≤ 10000/mm3) will be only registered, without randomization (Group D) and will receive the reference AraC+ group ,but without AraC during the first chemotherapy course ,and with reduced doses of AraC during the second and third course, followed by G-CSF. .
