In this single-center, open-label, Phase II study, nonrandomized,no control,prospective clinical trial,a total of 30 Philadelphia chromosome-positive acute lymphoblastic leukemia (Ph+ALL) patients will be enrolled.Patients will be diagnosed according to morphologic,immunologic, cytogenetic and molecular(MICM) criteria, including bone marrow morphology, immunophenotype, cytogenetic and molecular genetic (BCR/ABL gene, qualitative and quantitative analysis) examination.~Dasatinib 100 mg per day will be given orally along with combination chemotherapy starting day 8 of induction chemotherapy. Dasatinib will be given continuously (if it's tolerable) for 2 years since achievement of complete remission (CR) as part of consolidation chemotherapy and maintenance therapy.Patients can receive allogeneic hematopoietic stem cell transplantation (HSCT),or patients who keep BCR/ABL negative can receive autologous HSCT whenever possible during their first CR. Otherwise, they will finish the consolidation chemotherapy. Total duration of follow-up will be 2 year after last enrollment.~Pre-treatment evaluation will include complete blood count (CBC) with reticulocyte count, chemistry, electrolytes, coagulation, hepatitis profile, chest X-ray.Evaluation during treatment will include: CBC every two days during myelosuppression, chemistry, electrolytes, coagulation before each cycles of chemotherapy. Quantitative PCR (RQ-PCR) for Bcr-Abl will be done from bone marrow mononuclear cells at diagnosis, at CR, and before each cycles of consolidation chemotherapy,then every 3 months during maintenance therapy. For patients who undergo allogeneic HSCT, quantitative PCR for Bcr-Abl will be done from bone marrow mononuclear cells at the initiation of conditioning, and then every 3 months. PCR will be done in IS standardized lab.~Side effects of combination therapy will be monitored and described according to Common Toxicity Criteria, version 4.0 (National Cancer Institute, USA).~The purpose of current study is to determine the clinical efficacy and tolerability of combination therapy of Dasatinib with multi-agent chemotherapy in newly-diagnosed Ph+ ALL.
