Background
Malnutrition during cancer treatment increases treatment‐related morbidity and mortality. Our study better characterizes variability in malnutrition identification and treatment by ...examining nutrition‐related diagnoses and support for children with central nervous system (CNS) and non‐CNS solid tumors during therapy. We examined diagnosis of malnutrition, use of tube feeding or parenteral nutrition (PN), and appetite stimulants.
Methods
We retrospectively reviewed 0 to 21‐year‐old patients in the Pediatric Health Information System from 2015 to 2019. Patients were classified as having (1) billed malnutrition diagnosis, (2) malnutrition diagnosis or using PN and enteral nutrition (“functional malnutrition”), and (3) any previous criteria or prescribed appetite stimulants (“possible malnutrition”), as well as associated risk factors.
Results
Among 13,375 unique patients, CNS tumors were most common (24.4%). Overall, 26.5% of patients had malnutrition diagnoses, 45.4% met functional malnutrition criteria, and 56.0% had possible malnutrition. Patients with adrenal tumors had highest billed, functional, and possible malnutrition (36.6%, 64.1%, and 69.4%, respectively) followed by CNS tumors (29.1%, 52.4%, and 64.1%). Patients with adrenal tumors had highest rates of PN use (47.4%) and those with CNS tumors had the highest tube feeding use (26.8%). Hospital admissions with malnutrition had a longer hospital length of stay (LOS) (6 vs 3 days, P < 0.0001), more emergency department admissions (24.4% vs 21.8%, P < 0.0001), and more opioid use (58.6% vs 41.4%, P < 0.0001).
Conclusions
Variability in malnutrition diagnoses hinders clinical care and nutrition research in pediatric oncology. Improving disease‐specific recognition and treatment of malnutrition can target nutrition support, ensure appropriate reimbursement, and potentially improve outcomes for children with solid tumors.

Malnutrition and cachexia during pediatric cancer treatment worsen toxicity and quality-of-life. Clinical practice varies with lack of standard malnutrition definition and nutrition interventions. ...This scoping review highlights available malnutrition screening and intervention data in childhood cancer and the need for standardizing assessment and treatment.
Ovid Medline, CINAHL, and Cochrane Library were searched for studies containing malnutrition as the primary outcome with anthropometric, radiographic, or biochemical measurements. Secondary outcomes included validated nutritional assessment or screening tools. Two authors reviewed full manuscripts for inclusion. Narrative analysis was chosen over statistical analysis due to study heterogeneity.
The search yielded 234 articles and 17 articles identified from reference searching. Nine met inclusion criteria with six nutritional intervention studies (examining appetite stimulants, nutrition supplementation, and proactive feeding tubes) and three nutritional screening studies (algorithms or nutrition support teams) each with variable measures and outcomes. Both laboratory evaluations (albumin, prealbumin, total protein) and body measurement (weight loss, mid-upper arm circumference) were used. Studies demonstrated improved weight, without difference between formula or appetite stimulant used. Screening studies yielded mixed results on preventing weight loss, weight gain, and survival.
Our review demonstrated a paucity of evidence for malnutrition screening and intervention in pediatric cancer treatment. While a variety of malnutrition outcomes, interventions, and screening tools exist, nutritional interventions increased weight and decreased complications. Screening tools decreased malnutrition risk and may improve weight gain. Potential age- and disease-specific nutritional benefits and toxicities also exist, further highlighting the benefit of standardizing malnutrition definitions, screening, and interventions.
Since the original description of pathogenic germline DICER1 variation underlying pleuropulmonary blastoma (PPB), the spectrum of extrapulmonary neoplasms known to be associated with DICER1 has ...continued to expand and now includes tumors of the ovary, thyroid, kidney, eye, and brain among other sites. This report documents our experience with another manifestation: a primitive sarcoma that resembles PPB and DICER1-associated sarcoma of the kidney. These tumors are distinguished by their unusual location in the peritoneal cavity, associated with visceral and/or parietal mesothelium. A total of seven cases were identified through pathology review in children presenting at a median age of 13 years (range 3-14 years). Primary sites of origin included the fallopian tube (four cases), serosal surface of the colon (one case), and pelvic sidewall (two cases). One case had pathologic features of type I PPB, another type Ir (regressed) PPB, and the remaining five had features of type II or III PPB with a mixed primitive sarcomatous pattern with or without cystic elements. All had a pathogenic DICER1 variation identified in germline and/or tumor DNA. PPB-like peritoneal tumors represent a newly described manifestation of DICER1 pathogenic variation whose pathologic features are also recapitulated in DICER1-related renal sarcoma, cervical embryonal rhabdomyosarcoma, and some Sertoli-Leydig cell tumors with heterologous elements. Tumors arising from the fallopian tube or elsewhere in the abdomen/pelvis, especially those with heterogeneous rhabdomyosarcomatous and/or cartilaginous differentiation, should prompt consideration of germline and tumor DICER1 testing.

Growth differentiation factor 15 (GDF15), an inflammatory marker and mediator of adult cancer cachexia, remains largely unexplored in children. GDF15 increases nausea, vomiting, and anorexia in ...cancer and contributes to malnutrition, with the potential to be a cachexia therapeutic target. No studies have examined GDF15 in children with newly diagnosed cancer. Our pilot study compares GDF15 in children with newly diagnosed cancer to age- and sex-matched controls and correlates levels with anthropometric measurements and quality of life (QOL).
Children with newly diagnosed cancer aged 2-21 years were enrolled with serum GDF15 ELISA, anthropometric measures height, weight, and mid-upper arm circumference (MUAC), and QOL assessments (using PedsQL™ Core and Gastrointestinal Modules), which were collected at baseline and repeated 3 months later. Serum GDF15 levels were obtained from age- and sex-matched controls for comparison.
A total of 57 participants enrolled (N=30, cancer group; N=27, control group) with a median age of 8.8 years (IQR 5.6-15.9 years). The participants were primarily male (54.4%), white (82.5%), and non-Hispanic (82.5%). Cancer diagnoses included acute lymphoblastic leukemia (N=8), lymphoma (N=8), neuroblastoma (N=5), soft tissue tumors (N=4), acute myeloid leukemia (N=2), and single participants with brain, kidney, and bone tumors. Baseline GDF15 was higher in the cancer cohort compared to the control cohort (median=614.6pg/mL and 320.5pg/mL, respectively; p<0.001). When examining participants with evaluable baseline and 3-month follow-up GDF15 levels (N=18), GDF15 was not statistically different (median=657.1pg/mL and 675.3pg/mL, respectively; p=0.702). A total of 13 of the 30 participants and 21 caregivers completed the PedsQL™ Core and Gastrointestinal symptom modules. QOL scores did not differ significantly at 3-month follow-up compared to baseline, but diarrhea worsened (p=0.017). Median participant response for diarrhea at baseline was 92.9 (IQR=92.9-96.4; N=13), which was significantly better than the follow-up (median=78.6; IQR= 71.4-92.9; p=0.017). There were no correlations between change in height, weight, or MUAC and change in GDF15 levels (p=0.351, 0.920, and 0.269 respectively).
GDF15 was elevated in children with cancer at diagnosis compared to controls but did not correlate with anthropometric measurements or QOL. This pilot study will inform future prospective studies to better describe the natural history of GDF15 and its role in cachexia and as a potential therapeutic target.
Features associated with malnutrition are poorly elucidated in pediatric cancer care. We aimed to better understand characteristics associated with weight-for-height (WHZ) and height-for-age (HAZ) ...changes for infants and young children during cancer treatment. This retrospective study included 434 patients diagnosed <3 years old from 2007 to 2015 at a large pediatric cancer center. Patients starting treatment outside our center, those with relapsed or secondary malignancies, or with inaccurate information were excluded. Abstracted weights and heights for a 24-month period after treatment initiation were converted to sex-specific and age-specific z scores. Although not statistically different at baseline, patients with hematologic malignancies gained weight over time, while other tumor types did not. Higher treatment intensity and younger age at diagnosis increased odds of clinically significant weight loss. Older children had higher HAZ at diagnosis and HAZ also significantly decreased over time for all examined risk factors, which is distinctly different from patterns in WHZ over time. In conclusion, WHZ and HAZ are affected differently by cancer treatment in infants and young children. We identify key risk factors for weight loss and growth stunting which will be necessary to develop prospective trials to examine anthropometric, biochemical, and patient recorded outcomes around nutrition.
Clinical care and research around cancer cachexia in children is lacking. Cachexia increases treatment-related toxicity and long-term morbidity and potentially affects mortality. We highlight the ...urgent need for specific focus on childhood cancer cachexia and discuss potential solutions to inform cachexia therapeutics for children.
Abstract
Brain tumors have been the most common pediatric solid tumor and leading cause of morbidity and mortality. Improved survival emphasizes the importance of adverse treatment effects especially ...related to nutrition and exercise. Although studies have examined nutrition and exercise outcomes, few randomized trials exist. This narrative review included a systematic literature search with analysis of controlled or single group studies examining clinical and quality-of-life impact of nutrition or exercise interventions. Seven articles were included. Three nutrition studies demonstrated improvement with proactive feeding tubes, nutritional supplementation, and nutritional status. Two exercise studies showed improvement in measures of fitness and neuroanatomy with exercise in pediatric brain tumor survivors; two cohort studies demonstrated a link between quality of life and physical activity. Preliminary studies show nutrition and exercise may improve physical well-being and quality of life, suggesting future controlled studies are warranted to inform clinical care of children with brain tumors.
BACKGROUND
Hyperleukocytosis is a serious, life‐threatening complication of pediatric acute leukemia that can cause neurologic injury, pulmonary leukostasis, metabolic derangements, and coagulopathy. ...Acute leukemia has the highest risk of mortality and morbidity at presentation when associated with hyperleukocytosis. Infant leukemia presents unique challenges and treatment considerations due to the disease itself and size and overall health of the patient. While medical management of hyperleukocytosis in older patients with acute leukemia has been described, including cytoreductive procedures with automated leukapheresis (AL) or manual whole blood (WB) exchange transfusion, very little data exist for standardized management of hyperleukocytosis in infant leukemia patients.
CASE REPORTS
We describe four cases of infant acute leukemia presenting with hyperleukocytosis and leukostasis who each received manual WB exchange transfusions in conjunction with induction chemotherapy and review the existing literature on the use of procedural leukoreduction in infants with hyperleukocytosis. Special attention is given to challenges and technical aspects of leukapheresis in infants: when to perform manual WB exchange versus AL, optimal vascular access, blood product selection, exchange rates, and the monitoring for complications. Using published cases, we outline benefits versus risks of manual WB exchange and AL in infants less than 10 kg.
CONCLUSION
If providers perform procedural leukoreduction, the literature and our experience demonstrate manual WB exchange transfusion is favored over AL in infants less than 10 kg because of technical and complication risks associated with AL. Additional studies are needed to understand the impact of cytoreduction on long‐term outcomes.

Adult survivors of pediatric cancers are at substantial risk for infertility. Oncofertility is an emerging field in medicine that has focused on the fertility preservation of these patients. As the ...field continues to develop, there are several areas in which our practice has improved. However, several ethical concerns still exist involving beneficence, nonmaleficence, informed consent, adolescent assent, and posthumous use of reproductive tissues. Because the field is still developing, great disparities exist in available options depending on age, ability to pay, and geographic location. Such discrepancies in access may lead to health disparities in the adolescent patient population. As the science continues to make future fertility more feasible, the ethical questions will continue to be more complex. The purpose of this article is to review some of the developments regarding oncoferility and address future directions for research and inquiry in specific areas.
1. Understand the healthcare utilization of pediatric patients with cancer in their last 60 days of life who died on hospice care compared to those who did not receive hospice care and died in the ...hospital.
2. Consider factors that may contribute to earlier palliative care involvement leading to increased likelihood of hospice care in this study.
Detailing healthcare utilization and describing the hospice experience is important for both providers and families. In pediatric patients with cancer, enrolling in hospice when nearing end of life decreases hospitalizations and procedures and ultimately leads to more time spent at home.
Cancer is the leading cause of non-accidental pediatric deaths in the US. Palliative care is intricately related to the treatment of cancer, and hospice care is an important option for patients near end of life. Detailing healthcare utilization and describing the pediatric hospice experience is important for providers and families.
A retrospective cohort study using information from a pediatric palliative care database of deceased patients at a large academic center in 2020 and 2021. Inclusion criteria were patients receiving a palliative care consult with a cancer diagnosis who ultimately died. Health information from each patient's last 60 days of life was reviewed, comparing patients who died under hospice care to those who died in the hospital.
59 total patients were included. 39 died at home, and 20 died in the hospital. There was no statistical difference based on demographics. In their last 60 days of life, patients who died under hospice care spent fewer days in the hospital (2 vs 30.5), including in the ICU (0 vs 10.5). In addition, the hospice group underwent fewer procedures (0 vs 3.5) and spent fewer days utilizing mechanical ventilation (0 vs 3.5). The median number of days spent at home on hospice was 44. There were fewer days between consult and death in the non-hospice group (80 vs 451).
Pediatric patients with cancer spend more time at home near end of life under hospice care and are less likely to undergo invasive procedures or spend time in the ICU. Earlier palliative care consult correlates to home hospice care, but further study is needed to determine if there is cause.
