Study Details

Rituximab combined with a specific intensive chemotherapy is considered the standard treatment for newly diagnosed patients with mature B leukemia/lymphoma. However, the toxicity of this therapy is high. The purpose of this trial is to reduce the dose intensity of the chemotherapy blocks once the patient has achieved complete response. With this approach the investigators expect to maintain the efficacy and to reduce the toxicity of the chemotherapy, specially the rate of deaths in complete response.

Arms

  • Experimental: Chemotherapy
    Pts with biological age up to 55 y with advanced stage will receive 6 cycles of intensive treatment: blocks (A1-B1-C1-A2-B2-C2). If after A1 and B1 cycles CR is observed, the rest of the cycles will be administered with reduced doses. In pts with biological age \>55 y with advanced stage block will receive A and B with attenuated doses (A1\*-B1\*-A2\*-B2\*-A3\*-B3\*). Pts with biological age up to 55 y with localized stage (non-bulky I or II) with CR after 2 cycles will finish treatment after 4 blocks. If CR is not reached, patients will complete the 6 treatment cycles. Pts with a biological age \>55 y with localized stage (non-bulky I or II) with CR after 2 cycles will finish treatment after 4 attenuated blocks (A1\*-B1\*-A2\*-B2\*). If CR is not reached, patients will complete the 6 cycles of treatment.
