pediatric cancer cachexia

BACKGROUND: 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)...

The third most lethal cancer in the world is gastric adenocarcinoma, which is uncommon in children. Patients with gastric adenocarcinoma typically experience vomiting, abdominal pain, anemia, and weight loss. We present a case of a 14.5-year-old male with gastric adenocarcinoma that manifested as left hip pain, epigastric pain, dysphagia, weight loss, and melena. Physical exam revealed cachexia, jaundice, a palpable epigastric mass, palpable liver edge, and left hip tenderness. Laboratory tests showed microcytic anemia, increase in carcinoembryonic antigen (CEA), and abnormal liver function test...

Cachexia is a systemic wasting syndrome that increases cancer-associated mortality. How cachexia progressively and differentially impacts distinct tissues is largely unknown. Here, we find that the heart and skeletal muscle undergo wasting at early stages and are the tissues transcriptionally most impacted by cachexia. We also identify general and organ-specific transcriptional changes that indicate functional derangement by cachexia even in tissues that do not undergo wasting, such as the brain. Secreted factors constitute a top category of cancer-regulated genes in host tissues, and these changes include upregulation of the angiotensin-converting enzyme (ACE)...

BACKGROUND: 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. METHODS: Ovid Medline, CINAHL, and Cochrane Library were searched for studies containing malnutrition as the primary outcome with anthropometric, radiographic, or biochemical measurements...

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.

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...

BACKGROUND: Children with cancer are increasingly using cannabis therapeutically. AIM: The purpose of this study was to determine the perspectives and practices of pediatric oncologists and palliative care physicians regarding the use of cannabis for medical purposes among children with cancer. METHODS: A self-administered, voluntary, cross-sectional, deidentified online survey was sent to all pediatric oncologists and palliative care physicians in Canada between June and August 2020...

BACKGROUND: Mitochondrial neurogastrointestinal encephalomyopathy (MNGIE) is a progressive autosomal recessive disorder characterized by cachexia, gastrointestinal (GI) dysmotility, ptosis, peripheral neuropathy, and brain magnetic resonance imaging (MRI) white matter changes. Bi-allelic TYMP mutations lead to deficient thymidine phosphorylase (TP) activity, toxic accumulation of plasma nucleosides (thymidine and deoxyuridine), nucleotide pool imbalances, and mitochondrial DNA (mtDNA) instability...

In Minnesota, medical cannabis was approved for use in 2014. From July 2015 to February 2019, our center certified 103 pediatric and young adult patients for the use of medical cannabis under the qualifying conditions of cancer and treatment-related symptoms. Here, we provide a review of the literature on medical cannabis use in pediatric and young adult cancer patients. We also provide demographic data on our patients certified for medical cannabis. The most common diagnoses were leukemia/lymphoma (36%), brain tumors (37%), and malignant solid tumors (26%)...

Although the effectiveness of subarachnoid continuous drug infusion has been established in cancer pain management, its clinical use in children is rare. A 14-year-old girl with neurofibromatosis type I complained of right leg pain stemming from a growing tumor on her right buttock. Continuous and breakthrough right leg pain were unbearable, even at high doses of systemic opioids that caused severe constipation and deep sedation. Subsequent continuous infusion of bupivacaine and morphine through a subarachnoid catheter effectively relieved the girl's pain...

In this review we introduce the concept of the tumor macroenvironment and explore it in the context of metabolism. Tumor cells interact with the tumor microenvironment including immune cells. Blood and lymph vessels are the critical components that deliver nutrients to the tumor and also connect the tumor to the macroenvironment. Several factors are then released from the tumor itself but potentially also from the tumor microenvironment, influencing the metabolism of distant tissues and organs. Amino acids, and distinct lipid and lipoprotein species can be essential for further tumor growth...

BACKGROUND: Emesis and nausea are side effects induced by chemotherapy. These effects lead to enormous stress and strain on cancer patients. Further consequences may include restrictions in quality of life, cachexia or therapy avoidance. Evidence suggests that cancer patients develop the side effects of nausea and vomiting in anticipation of chemotherapy. Contextual cues such as smell, sounds or even the sight of the clinic may evoke anticipatory nausea and vomiting prior to infusion...

The measurement of energy expenditure (EE) is recommended as an important component of comprehensive clinical nutrition assessments in patients with altered metabolic states, who failed to respond to nutrition support and with critical illness that require individualized nutrition support. There is evidence that EE is variable in patients with metabolic diseases, such as chronic renal disease, cirrhosis, HIV, cancer cachexia, cystic fibrosis and patients under intensive care. By using appropriate techniques and interpretations of basal or resting EE, clinicians can facilitate the adequate nutrition support with minimum negative impacts from under- or overfeeding in these patients...

Adequate nutrition during cancer plays a decisive role in several clinical outcome measures, such as treatment response, quality of life, and cost of care. However, the importance of nutrition in children and young adults with malignancies is still an underestimated topic within pediatric oncology. The importance of our work is to reinforce and indicate that malnutrition in children with cancer should not be accepted at any stage of the disease or tolerated as an inevitable process. Unique to our manuscript is the close collaboration, the exchange of knowledge and expertise between pediatric oncologists and a nutritional specialist, as well as the comprehension of the mechanisms during cancer cachexia and malnutrition...

Cachexia affects up to two thirds of all cancer patients and is a significant cause of morbidity and mortality. It is a complex metabolic syndrome associated with the underlying illness and characterized by loss of skeletal muscle tissue with or without loss of fat mass. Cachexia's other prominent clinical symptoms include anorexia, systemic inflammation, pediatric growth failure, and hypogonadism. The relationship between the symptoms of cancer cachexia and the underlying illness is unclear, and there is an urgent need for a better understanding of the pathophysiology of this syndrome...

BACKGROUND: The aim of nutritional therapy in cancer patients is to prevent weight loss and to improve functional capacity and quality of life. Clinical studies however, have continued to demonstrate that a reduction in body weight loss is difficult to achieve in cancer cachexia. Several studies have shown that supplementation with eicosapentaenoic acid (EPA), an omega-3 fatty acid, has anti-cachectic effects in adult cancer patients. This study evaluated the clinical effects of a protein and energy dense EPA containing nutritional supplement in a group of pediatric cancer patients receiving active chemotherapy treatment...

It is clear that cancer patients develop complex nutrition issues. Nutrition support may or may not be indicated in these patients depending on individual patient characteristics. This review article, the first in a series of articles to examine the A.S.P.E.N. Guidelines for the Use of Parenteral and Enteral Nutrition in Adult and Pediatric Patients Cancer Guidelines, evaluates the evidence related to the use of nutrition screening and nutrition assessment in cancer patients. This first article will provide background concerning nutrition issues in cancer patients as well as discuss the role of nutrition screening and nutrition assessment in the care of cancer patients...

Over the past few decades, great progress has been made in the survival rates of childhood cancer. As survival rates have improved, there has been an increased focus on supportive care. Nutrition is a supportive-care modality that has been associated with improved tolerance to chemotherapy, improved survival, increased quality of life, and decreased risk of infection in children undergoing anticancer therapy. Guidelines and assessment criteria have been proposed for the nutrition management of a child with cancer; however, there is no consistent use of criteria among institutions treating children with cancer...

BACKGROUND: Anorexia is a common symptom in patients with cancer, which can lead to poor tolerance of treatment and can contribute to cachexia in extreme cases. Children with advanced-stage cancer are especially vulnerable to malnutrition resulting from anorexia and cachexia. Currently, there are no instruments that measure common concerns specifically associated with anorexia and cachexia in children with cancer. The purpose of the current article was to test the psychometric properties of a newly developed pediatric Functional Assessment of Anorexia and Cachexia Therapy (peds-FAACT) for children with cancer...
