Eating behavior and BMI in adolescent survivors of brain tumor and acute lymphoblastic leukemia

Adaptation of Family-Based Healthy Weight Program for Children who Survived Leukemia

Objective

Understand the perspectives of children who survived acute lymphoblastic leukemia (ALL) and their parents to adapt a guideline-based, family-based, intensive health behavior and lifestyle intervention treatment for this population.

Methods

Nine children 8-17 years of age [median = 12 years (IQR 10-16), median years off treatment = 5 (2-7)] who survived ALL and eleven parents participated in focus groups to assess perceptions of weight, weight-related behaviors, and perceived barriers to FBT. Responses were analyzed thematically, and resultant adaptations were guided by the Framework for Reporting Adaptations and Modifications-Enhanced (FRAME).

Results

Topics and themes identified included mental and physical health concerns (e.g., treatment-related medical complications, body esteem), a perception of excess weight as protective, the continuing influence of eating habits established during cancer treatment (e.g., instrumental feeding practices, snacking), and potential barriers to activity (i.e., physical limitations, lack of sport experience). Resultant adaptations to FBT were contextual (e.g., virtual delivery) and related to the content, including an emphasis on weight management in the context of survivorship; education about late effects, overweight and obesity; increased emphasis on structured eating patterns and instrumental eating; provider recommended physical activity; and tailored emotion-focused and body esteem content.

Conclusions

Focus groups for children who survived pediatric ALL provided insights that aided the adaptation of FBT for this population. A pilot trial of FBT for children who survived ALL and their parents is underway to evaluate acceptability, feasibility, and preliminary efficacy.

Food Insecurity and Nutritional Challenges in Adolescent and Young Adult Cancer Survivors in the U.S.A.: A Narrative Review and Call to Action

Advancements in cancer treatments over the past several decades have led to improved cancer survival in adolescents and young adults (AYAs, ages 15–39 years). However, AYA cancer survivors are at an increased risk for “late effects”, including cardiovascular, pulmonary and bone diseases as well as fatigue, infertility and secondary cancers. The treatments for cancer may also alter taste, lead to nutritional deficiencies and increase financial burdens that, when taken together, may increase the risk of food and nutrition security in AYA cancer survivors. Furthermore, although AYAs are often merged together in cancer survivorship studies, adolescents and young adults have distinct developmental, psychosocial and pathophysiological differences that may modify their risk of nutritional challenges. In this narrative review and “Call to Action”, rationale is provided for why there is a need to better understand nutritional challenges and food insecurity in AYA cancer survivors as a special population. Then, recommendations for next steps to advance knowledge and policy in this field are provided. In particular, integrating screening for food and nutrition insecurity and enhancing awareness of existing resources (e.g., the Supplemental Nutrition Assistance Program, SNAP) might help AYA cancer survivors combat nutritional deficiencies and reduce late effects while improving their overall survival and quality of life.

The urgent need to improve childhood cancer cachexia

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.

The Addition of Ferritin Enhanced the Prognostic Value of International Prognostic Index in Diffuse Large B‐Cell Lymphoma

Diffuse large B-cell lymphoma (DLBCL) is a highly heterogeneous non-Hodgkin lymphoma, and the prognosis of DLBCL patients is widely affected by multivariables. Clinical-factors-based prognostic systems stratify the prognosis of DLBCL with certain limitations, and the value of ferritin on the prognosis of DLBCL is unclear. In this study, 225 cases were retrieved from 4 centers of Huaihai Lymphoma Working Group (HHLWG) as the derivation cohort, and 66 cases were from the other 6 centers of HHLWG as external validation cohort. X-Tile program divided ferritin into three groups when applying 175.00 and 391.90 μg/L as the optimal cutoff points. Based on multivariable analysis, ferritin appeared to be a stronger predictor. A total of three variables (ferritin, age, and lactate dehydrogenase) were included for the development of the nomogram. The C-indexes were 0.73 and 0.70 in the derivation and validation cohort, and the calibration curve showed the consistency between the nomogram prediction and the actual observation. In conclusion, Ferritin-based nomogram enhanced the prognostic value of IPI in DLBCL.

Poor diet quality and adverse eating behaviors in young survivors of childhood cancer

BACKGROUND

The long-term impact of childhood cancer treatment on dietary intake is likely to be complex, and the length of time dietary behaviors are affected after childhood cancer treatment is unknown.

AIM

The aim of this study was to determine the diet quality in childhood cancer survivors recently off treatment and explore possible contributing factors that may affect diet quality in this population.

METHODS

Participants were 65 parents and/or carers of childhood cancer survivors (CCS) (aged 2-18 years), recently off treatment, and 81 age-matched controls. Participants completed two self-administered dietary intake and eating behavior questionnaires. Study data were explored to determine between group differences, bivariate analysis using Spearman correlations was used to determine the relationship between diet quality and identified variables, and hierarchical cluster analysis was completed to characterize specific variables into clusters.

RESULTS

One hundred and forty-six parents of children aged 2-18 years completed the study (65 parents of CCS and 81 control). CCS had a significantly poorer diet quality score than the age-matched controls (32.25 vs 34.83, P = 0.028). CCS had significantly higher parent-reported rates of "picky eating" behavior than the control group (2.31 vs 1.91; P = 0.044). Factors such as picky eating, emotional overeating, and body mass index z-score might drive diet quality in survivors.

CONCLUSIONS

CCS were found to have poorer diet quality and more likely to have parents report picky eating behaviors. The outcomes highlighted the need for a tailored intervention aimed at improving healthy eating behaviors in CCS after treatment for cancer.

Nutritional Status of Pediatric Cancer Patients at Diagnosis and Correlations with Treatment, Clinical Outcome and the Long-Term Growth and Health of Survivors

Malnutrition is caused either by cancer itself or by its treatment, and affects the clinical outcome, the quality of life (QOL), and the overall survival (OS) of the patient. However, malnutrition in children with cancer should not be accepted or tolerated as an inevitable procedure at any stage of the disease. A review of the international literature from 2014 to 2019 was performed. Despite the difficulty of accurately assessing the prevalence of malnutrition, poor nutritional status has adverse effects from diagnosis to subsequent survival. Nutritional status (NS) at diagnosis relates to undernutrition, while correlations with clinical outcome are still unclear. Malnutrition adversely affects health-related quality of life (HRQOL) in children with cancer and collective evidence constantly shows poor nutritional quality in childhood cancer survivors (CCSs). Nutritional assessment and early intervention in pediatric cancer patients could minimize the side effects of treatment, improve their survival, and reduce the risk of nutritional morbidity with a positive impact on QOL, in view of the potentially manageable nature of this risk factor.

Abnormal weight gain with fatigue and stress in early survivorship after childhood brain tumor diagnosis

BACKGROUND

Diagnosis and treatment for individuals with brain tumors during childhood involves sequelae, including abnormal weight gain. This symptom is commonly clustered with fatigue and increased risk for cardiovascular disease. Children's Oncology Group recommendations include annual surveillance of body mass index (BMI) and cardiometabolic comorbidities; however, there has been little emphasis on individualized screening early in survivorship.

PURPOSE

The primary purpose of this paper is to describe the findings of abnormal weight gain and its correlates in a sample of young childhood brain tumor survivors during early survivorship.

DESIGN AND METHODS

This cross-sectional multi-site study included brain tumor survivors of ages 8-12 years who were less than 6 years posttreatment. Convenience sampling from two pediatric cancer centers in the southern United States was utilized. Data collected included BMI, parent report of sleep, and child report of fatigue and stress.

RESULTS

The sample (N = 21) consisted of children who had received chemotherapy, radiation treatment, and surgery for childhood brain tumor. BMI in overweight and obese categories exceeded normative samples with 38% at or above the 85th percentile. There were clinically significant relationships with fatigue, stress about weight, tumor location, cranial radiation, chemotherapy, and recurrence PRACTICE IMPLICATIONS: Screening for abnormal weight gain and related factors, such as fatigue should begin early in survivorship after childhood brain tumor treatment completion with the aim of health promotion and disease prevention. Adiposity measurement techniques should be utilized in future clinical and research settings to improve assessment of cardiometabolic risk.

Nutritional concerns of survivors of childhood cancer: A "First World" perspective

Childhood cancer survivor (CCS) numbers are increasing as a result of advances in both treatment and supportive care. This positive outcome is tempered by the recognition of a high burden of chronic health conditions. Here, we review the nutritional concerns of CCS, including dietary habits after treatment and the factors during treatment that may contribute to chronic health conditions. Dietary interventions that have been conducted in CCS will be summarized along with focused goals of these interventions. We will also address the need to leverage these interventions to reduce the risk of chronic disease in CCS.

Nutritional status and appetite-regulating hormones in early treatment of acute lymphoblastic leukemia among children and adolescents: a cohort study

BACKGROUND

Children with acute lymphoblastic leukemia are at risk of malnutrition, but few studies have described the changes in nutritional status during the different phases of chemotherapy.

OBJECTIVE

To evaluate changes in nutritional status, food intake and appetite-regulating hormones among children and adolescents with acute lymphoblastic leukemia in the first phase of chemotherapy.

DESIGN AND SETTING

Cohort study developed in the pediatric oncology departments of two hospitals in the city of Natal, Rio Grande do Norte, Brazil.

METHODS

Fourteen children/adolescents (mean age of 7 years; 50% female) with acute lymphoblastic leukemia were monitored over the 28 days of an induction chemotherapy cycle. Anthropometric measurements, 24-hours food weight records and appetite-regulating hormone levels (ghrelin, leptin, insulin and cortisol) were obtained at three different times (before, in the middle and at the end of the induction phase).

RESULTS

Most of the patients (85.7%) had normal weight at the beginning of the treatment, and this did not change significantly during the 28 days. Energy and nutrient intakes improved from the start of the treatment to the midpoint, according to the ghrelin levels (from 511.1 ± 8.3 to 519.3 ± 6.6 pg/ml; P = 0.027). Other appetite-regulating hormones did not present changes.

CONCLUSION

Food consumption improves during the first phase of treatment, without alterations in anthropometric nutritional status.

Integrative Medicine in Childhood Cancer

The diagnosis of cancer in a child leaves parents and families devastated and vulnerable. In an effort to do everything possible, families often choose an integrative medicine approach to their child's care. Surveys have found that 31%-84% of children with cancer use complementary and alternative medicine and most often as supportive care agents. Several systematic reviews have demonstrated a clinical benefit for some select therapies; however, the safety and efficacy of the combination of biological therapies with conventional treatment remain largely unknown and garner concern due to the potential for interactions with conventional therapy. Given the sustained use and potential benefit of integrative medicine, additional research is warranted in pediatric oncology. Utilizing the available literature, clinical providers should aim to conduct open and nonjudgmental discussions with families about the use of integrative medicine so as to guide the safe integration of the two modalities.

The Effect of Soy Nut Compared to Cowpea Nut on Body Weight, Blood Cells, Inflammatory Markers and Chemotherapy Complications in Children with Acute Lymphoblastic Leukemia: A Randomized Controlled Clinical Trial

No previous studies were found to examine the effect of soy as a whole food on patients with leukemia. The present randomized controlled clinical trial studied the effect of soy nut on children with B-cell acute lymphoblastic leukemia (ALL) who were in the maintenance phase of chemotherapy. The eligible patients were randomized to receive 30 g/day soy or cowpea nut powder for 12 weeks. Dietary intake, physical activity, anthropometric measurements, complete blood count, serum albumin, serum highly sensitive C-reactive protein (hs-CRP), and Tumor necrosis factor alpha (TNF-α) as well as chemotherapy side effects were assessed at the start and the end of the study. In total 29 and 27 children completed the study (aged 6.34 ± 2.44 and 5.85 ± 2.35 years) in soy and cowpea nut groups, respectively. The total energy and protein intake, and physical activity as well as body weight, body mass index, number of red blood cells, hemoglobin and hematocrit levels, and fatigue were significantly improved in the soy nut group compared to patients who consumed cowpea nut (P < 0.05). Soy nut intake might improve the nutritional status, anemia, and fatigue in children with ALL. Studies targeting blood cell fractions and disease recurrence are highly recommended.

Overweight, obesity and adiposity in survivors of childhood brain tumours: a systematic review and meta-analysis

Survivors of childhood brain tumours (SCBT) have increased cardiometabolic risks, but the determinants of these risks are unclear. This systematic review aims to compare the prevalence of overweight and obesity as well as adiposity measures between SCBT and non-cancer controls. The PubMed, EMBASE, MEDLINE, CINAHL and the Cochrane Library databases were searched. The primary outcomes were the prevalence of overweight and obesity based on body mass index. The secondary outcomes were adiposity measures including percent fat mass, waist-to-hip and waist-to-height ratios. Forty-one studies were included in the meta-analysis. The prevalence of overweight and obesity combined was similar between overall SCBT, SCBT excluding craniopharyngioma and non-cancer controls (42.6%, 95% CI 30.1-55.1 vs. 31.7%, 95% CI 20.4-43.0 vs. 40.4%, 95% CI 34.0-46.8). We also found that SCBT have higher percent fat mass (mean difference 4.1%, 95% CI 2.0-6.1), waist-to-hip ratio (mean difference 0.07, 95% CI 0.02-0.13) and waist-to-height ratio (mean difference 0.06, 95% CI 0.01-0.10) than non-cancer controls. We conclude that SCBT have similar overweight and obesity distribution but higher adiposity than non-cancer controls. More studies were needed to explore the determinants of adiposity and its contribution to cardiometabolic outcomes in SCBT.

The effectiveness of interventions to treat hypothalamic obesity in survivors of childhood brain tumours: a systematic review

BACKGROUND

Survivors of childhood brain tumours (SCBT) are at risk of type 2 diabetes and cardiovascular diseases. Obesity is a major driver of cardiometabolic diseases in the general population, and interventions that tackle obesity may lower the risk of these chronic diseases. The goal of this systematic review was to summarize current evidence for the presence of interventions to manage obesity, including hypothalamic obesity, in SCBT.

METHODS

The primary outcome of this review was the body mass index z-score change from baseline to the end of the intervention and/or follow-up. Literature searches were conducted in PsycINFO, CINAHL, the Cochrane Library, Medline, SPORTDiscus, EMBASE and PubMed. Two reviewers completed study evaluations independently.

RESULTS

Eleven publications were included in this systematic review (lifestyle intervention n = 2, pharmacotherapy n = 6 and bariatric surgery n = 3). While some studies demonstrated effectiveness of interventions to manage obesity in SCBT and alter markers of obesity and cardiometabolic risk, the evidence base was limited and of low quality, and studies focused on hypothalamic obesity. We conclude that there is urgent need to conduct adequately powered trials of sufficient duration, using existing and novel therapies to manage obesity, reduce the burden of cardiometabolic disorders and improve outcomes in SCBT.

Association of Dysfunctional Eating Patterns and Metabolic Risk Factors for Cardiovascular Disease among Latinos

BACKGROUND

Latinos are at high risk for cardiovascular disease (CVD). Identifying behavioral factors associated with CVD risk in this population may provide novel targets for further research to reduce chronic disease disparities. Dysfunctional eating patterns (emotional eating [EE], uncontrolled eating [UE], and cognitive restraint of eating [CR]) may be associated with CVD risk but little is known about this relationship in Latinos.

OBJECTIVE

The aim of this study was to examine associations between dysfunctional eating patterns and metabolic risk factors for CVD in Latinos.

DESIGN

The study used a cross-sectional design.

PARTICIPANTS/SETTING

Latino individuals (n=602), aged 21 to 84 years, were enrolled in the study from September 2011 to May 2013 from a community health center that serves 80% to 85% of the Latino population in Lawrence, MA. Individuals with complete data were included in this analysis (n=578).

MEASURES

Dysfunctional eating patterns were measured with the Three Factor Eating Questionnaire-R18V2. CVD risk factors examined included obesity assessed by body mass index and waist circumference and diagnoses of type 2 diabetes, hypertension, and hyperlipidemia abstracted from electronic health records.

STATISTICAL ANALYSIS

Multivariable logistic and Poisson regressions adjusting for age, sex, perceived income, employment, education, physical activity, and perceived stress were performed. The no dysfunctional eating category (ie, no EE, no UE, or no CR) was used as the reference category in all analyses.

RESULTS

High EE was associated with greater odds of obesity (odds ratio [OR] 2.19, 95% CI 1.38 to 3.45) and central obesity (OR 2.97, 95% CI 1.81 to 4.87), and diagnosis of type 2 diabetes (OR 1.99, 95% CI 1.13 to 3.48) and hypertension (OR 2.01, 95% CI 1.16 to 3.48). High UE was associated with obesity (OR 1.96, 95% CI 1.20 to 3.21) and central obesity (OR 2.33, 95% CI 1.38 to 3.94). Low and high CR were associated with obesity (OR 2.26, 95% CI 1.43 to 3.56 and OR 2.77, 95% CI 1.75 to 4.37, respectively) and central obesity (OR 2.04, 95% CI 1.25 to 3.32 and 2.51, 95% CI 1.54 to 4.08, respectively) and diagnosis of type 2 diabetes (OR 1.83, 95% CI 1.05 to 3.16 and OR 2.73, 95% CI 1.58 to 4.70, respectively) and hyperlipidemia (OR 1.94, 95% CI 1.16 to 3.24 and OR 2.14, 95% CI 1.28 to 3.55, respectively). Lastly, high EE and low and high CR were associated with increased odds of having a greater number of metabolic CVD risk factors (incidence-rate ratio [IRR] 1.33, 95% CI 1.13 to 1.58; IRR 1.34, 95% CI 1.13 to 1.58; and IRR 1.44, 95% CI 1.22 to 1.71, respectively).

CONCLUSIONS

Dysfunctional eating patterns were positively associated with metabolic CVD risk factors in this Latino sample, with dose-response relationships for some associations. Future studies are needed to determine whether dysfunctional eating patterns influence CVD risk factors among Latinos.

Lifestyle advice provision to teenage and young adult cancer patients: the perspective of health professionals in the UK

PURPOSE

Health professionals are an important source of information for teenage and young adult (TYA) cancer patients. However, little is known about health professionals' provision of lifestyle advice to young people with cancer who are in their care.

METHODS

An online survey was distributed to health professionals within the UK who identified themselves as working with TYA cancer patients. Health professional awareness of lifestyle guidance, provision of lifestyle advice to young people and views on lifestyle information format and delivery were explored.

RESULTS

Ninety-five health professionals (44% nurses; 28% allied health professionals; 17% physicians) completed the survey. The majority (72%) of respondents were aware of some lifestyle guidance for cancer patients. However, less than half of TYA health professionals (46%) were able to successfully recall the source of the guidelines and less than a third reported proving specific advice to the majority of their patients on weight management, smoking, alcohol consumption and sun safety. Many health professionals (38%) felt that they were not the right person to provide advice and cited lack of resources as a key barrier to advice provision. The majority (95%) reported being interested in a resource containing relevant lifestyle information that could be given to young people with cancer.

CONCLUSIONS

TYA health professionals' awareness of lifestyle guidance and provision of advice regarding health behaviour is sub-optimal. Clear and comprehensive guidance written specifically for TYA health professionals could overcome the reported barriers and improve professionals' confidence in addressing and providing advice on lifestyle to young people with cancer.

Parental Perceptions of Obesity and Obesity Risk Associated With Childhood Acute Lymphoblastic Leukemia

The prevalence of obesity and related comorbidities in survivors of childhood acute lymphoblastic leukemia (ALL) is well established and ranges anywhere from 29% to 69% depending on the study. We sought to explore the awareness of parents of survivors of childhood ALL regarding the increased risk of obesity and their perceptions regarding the overall health of their child. One hundred twenty-one parents of 99 survivors of pediatric ALL completed surveys regarding perceptions of obesity risk in survivors. Eighty percent of parents of overweight and obese survivors correctly identified their child as "a little overweight" or "overweight." Few parents recalled discussing weight gain (21%) or obesity risk (36%) with their practitioner. Parents that did recall having these discussions and/or reported a decreased level of posttherapy activity in their child were more likely to be concerned about their child's weight status. Improved awareness and education regarding the risk of obesity and associated comorbid conditions may provide an avenue for future prevention of obesity in survivors of pediatric ALL. Discussion and education regarding a healthy lifestyle, including proper diet and exercise, should be incorporated early in routine patient visits.

The effectiveness of interventions to treat obesity in survivors of childhood brain tumors: a systematic review protocol

BACKGROUND

Pediatric brain tumors are the most common solid tumors in children. Advances in understanding the hallmarks of cancer biology and novel therapies have led to an increasing number of survivors of childhood brain tumors (SCBT). However, these survivors are at an increased risk of obesity and cardiometabolic disorders that affect their quality of life and lifespan. It is important to define effective strategies to treat and prevent obesity in this population. This systematic review aims to investigate the effectiveness of lifestyle interventions, pharmacotherapy, and bariatric surgery on treating obesity in SCBT.

METHODS

Searches will be conducted in PubMed, MEDLINE, EMBASE, PsycINFO, SPORTDiscus, CINAHL, Cochrane Database of Systematic Review, Cochrane Central Register of Controlled Trials (CENTRAL), and Database of Abstracts of Reviews of Effect (DARE). In addition, ClinicalTrials.gov and ProQuest Dissertations and Theses A&I will be searched to identify relevant gray literature. The reference lists of eligible articles will be searched for additional studies. All screening, quality assessment, and data abstraction will be done independently by two reviewers. We will perform meta-analysis if there are sufficient studies.

DISCUSSION

This review will summarize evidence for the effectiveness of interventions used to reduce obesity risk in SCBT. This has significant implications for SCBT, as it can identify gaps in knowledge and provide insights into the development of new interventions to manage obesity in survivors, which may improve their outcomes.

Psychometric Analysis of the Three-Factor Eating Questionnaire-R18V2 in Adolescent and Young Adult-Aged Central Nervous System Tumor Survivors

PURPOSE

Adolescent and young adult (AYA)-aged central nervous system (CNS) tumor survivors are an understudied population that is at risk of developing adverse health outcomes, such as obesity. Long-term follow-up guidelines recommend monitoring those at risk of obesity, thus motivating the need for an eating behavior questionnaire. An abbreviated online version of the Three-Factor Eating Questionnaire (TFEQ-R18v2) has been developed, but its applicability to this population is not yet known. This study investigated the instrument's factor structure and reliability in this population.

METHODS

AYA-aged CNS tumor survivors (n = 114) aged 15-39 years completed the TFEQ-R18V2 questionnaire online. Confirmatory factor analysis was used to examine the fit of the three-factor structure (uncontrollable eating, cognitive restraint, and emotional eating [EE]) and reliability (internal consistency of the TFEQ-R18v2). Associations between the three factors and body mass index (BMI) were assessed by linear regression.

RESULTS

The theorized three-factor structure was supported in our population (RMSEA = 0.056 and CFI = 0.98) and demonstrated good reliability (α of 0.81-0.93). EE (β = 0.07, 95% CI 0.02-0.13) was positively associated with BMI, whereas the other two subscale scores were not.

CONCLUSION

The TFEQ-R18v2 instrument holds promise for research and clinical use among AYA-aged CNS tumor survivors. The instrument may be a useful tool for researchers to develop tailored weight management strategies. It also may be a valuable tool for clinicians to monitor survivors who are at risk of obesity and to facilitate referral. Our results also suggest that EE in this population should be further investigated as a potential target for intervention.

Increased Body Mass Index during Therapy for Childhood Acute Lymphoblastic Leukemia: A Significant and Underestimated Complication

Objective & Design. We undertook a retrospective review of children diagnosed with acute lymphoblastic leukemia (ALL) and treated with modern COG protocols (n = 80) to determine longitudinal changes in body mass index (BMI) and the prevalence of obesity compared with a healthy reference population. Results. At diagnosis, the majority of patients (77.5%) were in the healthy weight category. During treatment, increases in BMI z-scores were greater for females than males; the prevalence of obesity increased from 10.3% to 44.8% (P < 0.004) for females but remained relatively unchanged for males (9.8% to 13.7%, P = 0.7). Longitudinal analysis using linear mixed-effects identified associations between BMI z-scores and time-dependent interactions with sex (P = 0.0005), disease risk (P < 0.0001), age (P = 0.0001), and BMI z-score (P < 0.0001) at diagnosis and total dose of steroid during maintenance (P = 0.01). Predicted mean BMI z-scores at the end of therapy were greater for females with standard risk ALL irrespective of age at diagnosis and for males younger than 4 years of age at diagnosis with standard risk ALL. Conclusion. Females treated on standard risk protocols and younger males may be at greatest risk of becoming obese during treatment for ALL. These subgroups may benefit from intervention strategies to manage BMI during treatment for ALL.
