PURPOSE Asparaginase-associated pancreatitis (AAP) is common in patients with acute lymphoblastic leukemia (ALL), but risk differences across age groups both relation to first-time AAP and after asparaginase re-exposure have not been explored. PATIENTS AND METHODS We prospectively registered (n = 168) during treatment of 2,448 consecutive ALL aged 1.0-45.9 years diagnosed from July 2008 October 2018 treated according the Nordic Society Pediatric Hematology Oncology (NOPHO) ALL2008 protocol....
Abstract BACKGROUND Positron emission tomography (PET) scans of primary brain tumors were performed in pediatric patients to examine whether metabolic characteristics could be used as an index clinical aggressiveness. METHODS Twenty‐seven with untreated central nervous system neoplasms studied PET using 2‐[ 18 F] fluoro‐2‐deoxy‐D‐glucose (FDG) and/or L‐[methyl‐ 11 C] methionine (MET). Metabolic assessed FDG and MET standardized uptake values (SUV) SUV‐to‐normal ratios compared histopathology...
Background Interest has recently been paid to adolescents and young adults with acute lymphoblastic leukemia, particularly because all reports so far published indicate that these patients have a better outcome when treated pediatric rather than adult therapeutic protocols. There are different biological subtypes of leukemia distinct features prognoses; the distribution is not well known among adolescents. We, therefore, studied in aged 10 25 years Finland.Design Methods This...
Abstract Background Despite the extensive literature on neuropsychological sequelae after treatment of childhood acute lymphoblastic leukemia (ALL), very‐long‐term neurocognitive outcome survivors is poorly studied. We assessed functioning in a population‐based cohort young adult ALL survivors. Procedure Neuropsychological testing was performed 64 an average 20 years diagnosis. The test battery included verbal intelligence quotient (VIQ) and performance (PIQ), memory function, orientation...
Background Therapy directed at the central nervous system (CNS) is an essential part of treatment for childhood acute lymphoblastic leukemia (ALL). The current evaluation CNS involvement based on cytomorphological examination cerebrospinal fluid (CSF) alone not as sensitive with low cell counts flow cytometric immunophenotyping (FCI) CSF. However, importance CSF blasts diagnosis uncertain. We sought to determine significance FCI in relation conventional morphological examination. Procedure...
Carboxypeptidase G2 (CPDG2 ) can be used as rescue treatment in cases of delayed methotrexate elimination (DME) and Mtx-induced nephrotoxicity.Between July 2008 December 2014, all children (1.0-17.9 years) the Nordic countries diagnosed with Philadelphia chromosome negative acute lymphoblastic leukemia (ALL) were treated according to Organization for Pediatric Hematology Oncology (NOPHO) ALL protocol, including administration six eight high-dose (5 g/m2 /24 hr) Mtx (HDMtx) courses. The...
