Parents' perception of treatment-related toxicity in children treated according to the NOPHO ALL2008 protocol for acute lymphoblastic leukemia.

This study aimed to assess how parents perceived treatment-related side effects during acute lymphoblastic leukemia (ALL) treatment. Parents of children 1-17.9 years at diagnosis in Sweden, Finland, and Denmark who were alive and in first remission ≥6 months after end of ALL treatment were asked to respond on specific items regarding how their child was affected by side effects related to vincristine (VCR), corticosteroids, peg-asparaginase (ASP), and maintenance therapy, as well as overall impact of these treatments, complications in general, and their perception of impact on their child in comparison with other children with ALL.

Quality of life in children and adolescents after treatment for acute lymphoblastic leukemia according to the NOPHO ALL2008 protocol.

Background: The improved outcome of childhood acute lymphoblastic leukemia (ALL) over the last decades has increased the importance of assessing late effects and health-related quality of life (HRQoL), particularly when evaluating and comparing outcomes in clinical trials. This study aimed to assess HRQoL in children treated for ALL according to the NOPHO ALL2008 protocol.

Procedure: Children, aged 1 to less than 18 years at diagnosis, alive in first remission, and their parents, were asked to complete PedsQL 4.

Pharmacokinetics of PEGasparaginase in Infants with Acute Lymphoblastic Leukemia.

Background: PEGasparaginase is known to be a critical drug for treating pediatric acute lymphoblastic leukemia (ALL), however, there is insufficient evidence to determine the optimal dose for infants who are less than one year of age at diagnosis. This international study was conducted to identify the pharmacokinetics of PEGasparaginase in infants with newly diagnosed ALL and gather insight into the clearance and dosing of this population.

Methods: Infants with ALL who received treatment with PEGasparaginase were included in our population pharmacokinetic assessment employing non-linear mixed effects modelling (NONMEM).

Sequelae and post-thrombotic syndrome after venous thromboembolism in acute lymphoblastic leukemia survivors treated on the NOPHO ALL2008 protocol.

The treatment of acute lymphoblastic leukemia (ALL) is frequently complicated by toxicity, including venous thromboembolism (VTE) affecting roughly 8% of patients. VTE can lead to post-thrombotic syndrome (PTS), a group of signs and symptoms developed as a complication to deep venous thrombosis (DVT), imposing risk of permanent disability and reduced quality of life (QoL). PTS prevalence ranges from 0% to 70%, reflecting very heterogenous cohorts and assessment tools.

Pancreas-related persisting sequelae in ALL survivors with a history of asparaginase-associated pancreatitis: A part of the ALL-STAR study.

Objectives: Asparaginase-associated pancreatitis (AAP) occurs in up to 18% of patients treated for acute lymphoblastic leukemia (ALL); however, long-term sequelae are largely unexplored. We aimed to explore pancreatic sequelae among ALL survivors with and without AAP.

Methods: We investigated pancreatic sequelae in a national cohort of ALL survivors, aged 1-45 years at ALL diagnosis treated according to the NOPHO-ALL2008 protocol and included sex- and age-matched community controls.
