Aims: Allogeneic haematopoietic stem cell transplantation (allo-HSCT) is a vital treatment for various paediatric malignant and nonmalignant diseases. The conditioning treatment before allo-HSCT is crucial for successful engraftment. Treosulfan, a cytotoxic prodrug, has gained popularity due to its lower toxicity compared to traditional alkylating agents used for conditioning treatment.

Iron deficiency is one of the most common nutritional deficiencies worldwide and is the leading cause of anemia in the pediatric population (microcytic, hypochromic anemia due to iron deficiency). Moreover, untreated iron deficiency can lead to various systemic consequences and can disrupt the child's development. Therefore, a team of experts from the Polish Pediatric Society, the Polish Society of Pediatric Oncology and Hematology, the Polish Neonatology Society, and the Polish Society of Family Medicine, based on a review of the current literature, their own clinical experience, and critical discussion, has developed updated guidelines for the diagnosis, prevention, and treatment of iron deficiency in children from birth to 18 years of age.

Background: A personalised approach to the treatment of acute myeloid leukemia (AML) in children and adolescents, as well as the development of supportive therapies, has significantly improved survival. Despite this, some patients still die before starting treatment or in an early phase of therapy before achieving remission. The study analysed the frequency, clinical features and risk factors for early deaths (ED) and treatment related deaths (TRD) of children and adolescents with AML.

Article Synopsis
  • Pediatric patients with primary refractory or relapsed B-cell non-Hodgkin lymphoma (B-NHL) have a poor prognosis, as indicated by a study of 76 patients treated in Poland from 1995 to 2022.
  • The 5-year overall survival probability was 76.7% and event-free survival probability was 72.9%, but outcomes worsened for those with disease progression or relapse, particularly with a 0.0% survival rate for relapsing patients.
  • Key factors affecting prognosis included elevated lactate dehydrogenase, presence of B symptoms, and advanced disease at diagnosis, with hematopoietic stem cell transplantation showing potential as the most effective salvage therapy.
