Brief summary
RATIONALE: Drugs used in chemotherapy work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Imatinib mesylate may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. A peripheral stem cell transplant may be able to replace blood-forming cells that were destroyed by chemotherapy. When the healthy stem cells are infused into the patient they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets. Giving combination chemotherapy together with imatinib mesylate and peripheral stem cell transplant may be an effective treatment for acute lymphoblastic leukemia. Nevertheless, in the last few years GIMEMA has pubblished a paper in which 100% of Ph+ ALL patients reach HCR only with Imatinib, without any chemiotherapy. Thus, this treatment will be implemented in patients pertaining to this category.

Pre-assignment details
We are reporting on the subset of patients that was treated according to amendment three, in which Imatinib was given only at induction.
Participants by arm
| Arm | Count |
|---|---|
| Philadelphia Positive, Imatinib Only in Induction Therapy In this protocol, adult Philadelphia positive acute lymphoblastic leukemia patients were treated with chemotherapy for induction and consolidation, followed by maintenance with imatinib. The protocol was subsequently amended and imatinib was incorporated in the induction and post-remission phase together with chemotherapy. Due to the toxicity of this combined approach, the protocol was further amended to a sequential scheme based on imatinib plus steroids as induction, followed by consolidation with chemotherapy plus imatinib and, when applicable, by a hematopoietic stem cell transplant.
Thus, we have analyzed only this subset of patients as it was not feasible to analyzed all patients enrolled due also to the disease itself. | 51 |
