Cancer care places a heavy economic burden on families and health systems, driven by high treatment costs, lengthy hospital stays, and the necessity for extensive travel to specialized facilities. To address this challenge, an integrated health care network (IHCN) was implemented for maintenance treatment in acute leukemia. The IHCN encompassed outpatient services provided by local physicians and synchronous telemedicine consultation with pediatric oncologists.

Background: Thromboembolic complications are well known in the treatment of childhood acute lymphoblastic leukemia. Over the years it has not been possible to reach a consensus on a possible prophylaxis of thromboembolic events during intensive therapy. Only the administration of enoxaparin was able to achieve evidence in the literature to date.

Patients' reports of their health status are increasingly used in hematopoietic stem cell transplantation (SCT) to better understand the negative impact on symptom burden and quality of life. Little is known regarding the implementation in routine clinical care, particularly how it can be used to improve supportive care. We sought to the evaluate feasibility of capturing daily patient-reported outcomes (PROs) in the acute phase of SCT to measure physical and psychosocial symptom burden.

Background: As one of the few modifiable risk factors, the importance of dietary patterns for both disease prevention and treatment outcome in pediatric oncology has gained increasing popularity. Malnutrition is associated with lower survival rates, tolerance to treatment, and quality of life. Yet, especially in children with malignancies, nutritional deterioration is common, and pediatric cancer patients often present with inadequate intake of micro- and macronutrients alike.

Febrile neutropenia secondary to chemotherapy is one of the most critical complications in cancer treatment. The aim of this study was to determine if an increase in the percentage of immature platelet fraction (IPF%) might predict early neutrophil recovery following cytostatic-dependent aplasia. A retrospective cohort study compared serial complete blood counts and the level of C-reactive protein (CRP) following induction chemotherapy for Ewing sarcoma and Non-Ewing sarcoma patients.

Infections in hematopoietic stem cell transplant (HSCT) remain one of the major causes for morbidity and mortality, and it is still unclear whether knowledge of microbial colonization is important. In this single-center study, we collected weekly surveillance cultures in pediatric recipients of allogenic HSCT from five different body regions and tested for bacteria and fungi. Between January 2010 and December 2021, we collected 1095 swabs from 57 recipients of allogeneic HSCTs (median age: 7.

Purpose: Serial assessment of health condition based on self-report made by children and their proxies has consistently shown a lack of congruence. The study explored the discrepancies between mother's, father's, and children's reports on health-related quality of life (HRQOL) during the first two months of pediatric cancer treatment.

Methods: In this cohort study, children and parents completed the generic and cancer-specific Pediatric Quality-of-Life Inventory (PedsQL) questionnaires at initial diagnosis and in the subsequent months.

Introduction: Mortality in children with hemato-oncologic disease admitted to a pediatric intensive care unit (PICU) is higher compared to the general population. The reasons for this fact remain unexplored. The aim of this study was to assess outcomes and trends in hemato-oncologic patients admitted to a PICU, with analytical emphasis on emergency admissions.

Importance: Patient-reported outcome measurements (PROMs) are emerging as an important component of adult cancer care, but little has been done with regard to PROMs for pediatric cancer care.

Objectives: To identify pediatric patients with cancer who are at risk of severe adverse effects of treatment and provide individualized supportive care using PROMs.

Design, Setting, And Participants: This single-center cohort study with PROMs implemented in daily clinical routine was conducted from May 1, 2020, to November 15, 2021, among pediatric patients with a cancer diagnosis or their proxies.

Background: Several stakeholders, including patients and health care providers, suggest symptom self-reporting measurements for a more patient-directed cancer control approach. However, services tailored to measure daily reporting and implementing it in clinical care are lacking. This study aimed to evaluate the feasibility and value of daily patient-reported outcome measures (PROMs) by children receiving chemotherapy for cancer.

Background: Malnutrition is common in children with cancer and is associated with adverse clinical outcomes. The need for supportive care is becoming ever more evident and the role of nutrition in oncology is still not sufficiently understood. In particular, the consequences of macro- and micronutrient deficiencies require further research.

Introduction: Sufficient empirical antimicrobial therapy in febrile patients with cancer is challenging, owing to the limited arsenal of available antibiotics in an era of growing resistance. Because of the emergence of gram-negative bacteria resistant to ceftazidime and piperacillin, a combination antibiotic therapy was employed that uses meropenem combined with gentamicin and/or vancomycin if the patient further deteriorates.

Methods: A retrospective cohort analysis was performed including all patients with catheter-associated bloodstream infections (BSIs) and treated for childhood cancer in a tertiary single centre between 1 January 2000 and 31 June 2018.
