Acute lymphoblastic leukemia (ALL) is a heterogeneous disorder, with the greatest prevalence in children, but it also affects adults, and has an increasing incidence with age. Chromosomal abnormalities in ALL have been frequently described, the most common is the Philadelphia chromosome (Ph). The resulting fusion gene, BCR-ABL1, encodes for a chimerical oncoprotein (BCR-ABL) with constitutive tyrosine kinase activity, which leads to uncontrolled cell proliferation, reduced apoptosis, and impaired cell adhesion. ⋯ Nilotinib is another BCR-ABL targeted agent that is similar in structure to imatinib but has significantly greater binding affinity. It also has demonstrated promising efficacy in Ph+ ALL but is still being evaluated in phase 2 trials. In this article, the authors reviewed current knowledge on novel tyrosine-kinase inhibitors in adult Ph+ ALL patients.

Review Meta Analysis
A meta-analysis and systematic review of the efficacy and safety of anticoagulants as cancer treatment: impact on survival and bleeding complications.
Preclinical evidence suggests that anticoagulants, in particular the low-molecular-weight heparins (LMWH), exert an antitumor effect, whereas clinical trials have reported conflicting results. The authors conducted a comprehensive, systematic review and meta-analysis of the evidence from randomized controlled trials (RCTs), to evaluate the impact of anticoagulants on survival and safety in cancer patients without venous thromboembolism. ⋯ Anticoagulants, particularly LMWH, significantly improved overall survival in cancer patients without venous thrombosis while increasing the risk for bleeding complications. However, given the limitations of available data, the use of anticoagulants as antineoplastic therapy cannot be recommended until additional RCTs confirm these results.
