WebbAbout 20% of B-cell ALL patients have “Philadelphia chromosome-like” (Ph- like) gene expression profiles and about half of Ph-like leukemias are CRLF2-positive. Patients with Ph-like leukemias respond poorly to conventional chemotherapy and have high rates of relapse. Therefore, new treatment modalities for Ph-like B-ALL are needed.
