Results of CoALL 07-03 study childhood ALL based on combined risk assessment by in vivo and in vitro pharmacosensitivity.

We conducted a clinical trial and report the long-term outcome of 773 children with acute lymphoblastic leukemia upon risk-adapted therapy accrued in trial CoALL 07-03 (from the Cooperative Study Group for Childhood Acute Lymphoblastic Leukemia). In a 2-step stratification, patients were allocated to receive either low- or high-risk treatment, based on initial white blood cell count, age, and immunophenotype. A second stratification was performed according to the results of in vitro pharmacosensitivity toward prednisolone, vincristine, and asparaginase (PVA score) and in vivo response after induction therapy (minimal residual disease [MRD]).

Therapy prolongation improves outcome in multisystem Langerhans cell histiocytosis.

Langerhans cell histiocytosis (LCH)-III tested risk-adjusted, intensified, longer treatment of multisystem LCH (MS-LCH), for which optimal therapy has been elusive. Stratified by risk organ involvement (high [RO+] or low [RO-] risk groups), > 400 patients were randomized. RO+ patients received 1 to 2 six-week courses of vinblastine+prednisone (Arm A) or vinblastine + prednisone + methotrexate (Arm B).

Doxorubicin or daunorubicin given upfront in a therapeutic window are equally effective in children with newly diagnosed acute lymphoblastic leukemia. A randomized comparison in trial CoALL 07-03.

Background: The anthracyclines daunorubicin (DNR) and doxorubicin (DOX) are among the most important drugs in the treatment of childhood acute lymphoblastic leukemia, however there are conflicting in vitro data about the comparative efficacy and equivalent doses of both anthracyclines. To address the question of in vivo efficacy of both anthracyclines, patients enrolled in the CoALL 07-03 trial were randomized to receive one single dose of either doxorubicin 30 mg/m(2) , daunorubicin 30 mg/m(2) , or daunorubicin 40 mg/m(2) upfront induction therapy.

Procedure: Children with newly diagnosed B-Precursor ALL or T-ALL were eligible for the randomized comparison.

Promising therapy results for lymphoid malignancies in children with chromosomal breakage syndromes (Ataxia teleangiectasia or Nijmegen-breakage syndrome): a retrospective survey.

Children with chromosomal instability syndromes have an increased risk of developing lymphoma and leukaemia. The treatment of these malignancies is hampered by therapy-associated toxicity and infectious complications. This retrospective analysis evaluated the therapy outcome of 38 children with Ataxia teleangiectasia or Nijmegen-breakage syndrome with acute lymphoblastic leukaemia (ALL, n = 9), Non-Hodgkin lymphoma (NHL, n = 28) and Hodgkin lymphoma (HL, n = 1).

[28-year old female patient with respiratory insufficiency, elevated liver enzymes, pancytopenia and fever].

We report on a 28-year old female patient with fever and severe respiratory insufficiency requiring mechanical ventilation. Cytomegalovirus pneumonia was diagnosed by bronchoalveolar lavage, and antiviral therapy was initiated. However fever persisted and laboratory workup showed pancytopenia and elevated liver enzymes.
