AALL1231: Combination Chemotherapy With or Without Bortezomib in Treating Younger Patients With Newly Diagnosed T-Cell Acute Lymphoblastic Leukemia or Stage II-IV T-Cell Lymphoblastic Lymphoma


  • T-cell Acute Lymphoblastic Leukemia
  • T-cell Acute Lymphoblastic Lymphoma


This randomized phase III trial compares how well combination chemotherapy works when given with or without bortezomib in treating patients with newly diagnosed T-cell acute lymphoblastic leukemia or stage II-IV T-cell lymphoblastic lymphoma. Bortezomib may help reduce the number of leukemia or lymphoma cells by blocking some of the enzymes needed for cell growth. It may also help chemotherapy work better by making cancer cells more sensitive to the drugs. It is not yet known if giving standard chemotherapy with or without bortezomib is more effective in treating T-cell acute lymphoblastic leukemia and T-cell lymphoblastic lymphoma.

Eligibility Criteria

  • Ages eligible for study: 2 years to 30 years (Child, Adult)

  • Patients must have newly diagnosed T-lymphoblastic leukemia (T-ALL) or T-lymphoblastic lymphoma (T-LLy) stages II-IV
