In a large cohort of patients, DCMR has an added value for predicting cardiac events during long-term follow-up, improving the differentiation between high-risk and low-risk patients. Patients with inducible WMA and following early revascularization, demonstrate lower cardiac event rates than patients with medical therapy alone.
Summary
Obesity is associated with poor outcomes in childhood acute lymphoblastic leukaemia (ALL). We explored whether severe treatment‐related toxicity and treatment delays could explain this observation. This study included 1 443 children aged 2·0–17·9 years with ALL treated with the Nordic Society of Pediatric Haematology and Oncology (NOPHO) ALL2008 non‐high‐risk protocol. Prospective treatment‐related toxicities registered every three‐month interval were used. Patients were classified according to sex‐ and age‐adjusted international childhood cut‐off values, corresponding to adult body mass index: underweight, <17 kg/m2; healthy weight, 17 to <25 kg/m2; overweight, 25 to <30 kg/m2; and obese, ≥30 kg/m2. Obese children had a higher incidence rate ratio (IRR) for severe toxic events {IRR: 1·55 [95% confidence interval (CI) 1·07–2·50]}, liver and kidney failures, bleeding, abdominal complication, suspected unexpected severe adverse reactions and hyperlipidaemia compared with healthy‐weight children. Obese children aged ≥10 years had increased IRRs for asparaginase‐related toxicities compared with healthy‐weight older children: thromboses [IRR 2·87 (95% CI 1·00–8·21)] and anaphylactic reactions [IRR 7·95 (95% CI 2·15–29·37)] as well as higher risk for truncation of asparaginase [IRR 3·54 (95% CI 1·67–7·50)]. The high prevalence of toxicity and a higher risk of truncation of asparaginase may play a role in the poor prognosis of obese children aged ≥10 years with ALL.
In selected cases, surgically placed jejunostomy tubes for feeding in children is an effective and safe method to overcome GERD, feeding difficulties, or recurrent pneumonia without major surgery.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
