Parent-provider communication dynamics during the pediatric oncology diagnostic process in Guatemala: A qualitative study.

Effective communication is founded on bidirectional participation from families and healthcare providers. In adult medicine, bidirectional communication promotes treatment adherence and builds the family-provider relationship. However, the relationship between communication styles in pediatrics remains poorly understood, particularly in culturally diverse settings. This study aims to investigate parent-provider communication dynamics and parental involvement during diagnostic cancer communication in Guatemala. This qualitative study included 20 families of children with cancer and 10 providers at Unidad Nacional de Oncología Pediátrica in Guatemala. Psychoeducation and diagnostic conversations between parents, psychologists, and oncologists were recorded and thematically analyzed using a priori and novel codes exploring communication behaviors, parental engagement, and interpersonal dynamics. Participating parents had children with various diagnoses. Only 15% of fathers and 5% of mothers reported education beyond primary school. Providers spoke 68% of words during psychoeducation and 85% of words during diagnosis conversations. Providers used supportive communication behaviors providing explanations, demonstrating verbal attentiveness, and soliciting questions and non-supportive behaviors including paternalistic talk. Parental participation was considered active when they asked questions, expressed hopes or concerns, or asserted their opinions, and non-active when participation was limited to brief responses to closed-ended questions. Supportive provider communication often encouraged active participation; non-supportive communication did not. Furthermore, active parental participation prompted supportive communication from providers, while non-active participation did not. Our findings highlight the bidirectional nature of effective communication, establishing that provider communication styles both influence and are influenced by parental participation, and emphasizing the importance of supportive provider communication for patient-centered care.

Radiotherapy-associated Sensorineural Hearing Loss in Pediatric Oncology Patients.

During the radiotherapeutic treatment of pediatric oncology patients, they would be at a latent risk of developing ionizing radiation-induced ototoxicity when the cochlea or auditory nerve is located within the radiation field. Sensorineural hearing loss (SNHL) is an irreversible late complication of radiotherapy, and its incidence depends on various factors such as the patient's hearing sensitivity, total radiation dose to the cochlea, radiotherapy fractionation regimen, age and chemoradiation. Importantly, this complication exhibits serious challenges to adult survivors of childhood cancer, as it has been linked to impairments in academic achievement, psychosocial development, independent living skills, and employment in the survivor population. Therefore, early detection and proper management can alleviate academic, speech, language, social, and psychological morbidity arising from hearing deficits. In the present review, we have addressed issues such as underlying mechanisms of radiation-induced SNHL, audiometric findings of pediatric cancer patients treated with radiotherapy, and management and protection measures against radiation-induced ototoxicity.

Health-related quality of life among pediatric patients with acute lymphoblastic leukemia: An exploratory cross-sectional study.

Improved survival rates broadened the pediatric oncology focus to include health-related quality of life (HRQoL). This cross-sectional study aimed to examine HRQoL by treatment phase and disease risk level in pediatric patients with B-cell acute lymphoblastic leukemia (B-ALL), including those in early survivorship. A subset of data from a larger prospective cohort study was analyzed. Data were collected from 73 patients (73 parent reports and 28 self-reports). Parent proxy and self-report PROMIS measures assessed HRQoL across treatment phases (early intensive, maintenance, and off treatment) and disease risk groups (standard vs high). Analyses assessed the relationship between parent proxy and patient self-reports and the differences in HRQoL among treatment phases and risk groups. Parent proxy reports generally indicated worse fatigue, pain interference, and mobility compared with patient self-reports. Self-reports in the early intensive treatment group suggested worse depressive symptoms, fatigue, mobility, and upper extremity function compared with those in later phases. Parent proxy reports showed worse fatigue and depressive symptoms in early intensive treatment group relative to those in later phases. Patient self-reports in the maintenance group demonstrated the best peer relationships scores. Parent proxy reports in the high-risk group reported significantly higher depressive symptoms and fatigue compared with the standard-risk group. Differences in HRQoL suggest targets for further assessment and intervention. The early treatment and immediate post-survivorship periods may represent particularly critical time points. Longitudinal studies with larger and diverse samples should further explore HRQoL trajectories in this population.

Sugar and sugar-sweetened beverages in relation to premature aging in adult survivors of childhood cancer.

Premature aging is a significant concern in adult survivors of childhood cancer as they develop aging-related conditions at a younger age than their peers with no history of childhood cancer. Although modifiable lifestyle factors, such as diet, are postulated to affect aging process, supporting evidence is sparse. We examined if the consumption of sugar and sugar-sweetened beverages was related to premature aging in 3322 adult survivors of childhood cancer in the St. Jude Lifetime Cohort. Premature aging was assessed using the Deficit Accumulation Index (DAI) that was a ratio of the number of age-related chronic health conditions each survivor had out of 44 conditions total. Multinomial logistic regressions adjusting for confounders were used to estimate odds ratios (ORs) and 95% confidence intervals (CIs). There were 46% of childhood cancer survivors consumed SSBs once or more times per day. High intake of sugar, especially sugars added to foods during preparation or processing, and habitual consumption of sugar-sweetened beverage were associated with an increased risk of premature aging. Our findings support a need to include strategies to reduce sugar and sugar-sweetened beverages consumption in lifestyle interventions to promote healthy aging in adult survivors of childhood cancer.

Baseline characteristics of parents enrolled in ACCL20N1CD: Financial distress during treatment for pediatric acute lymphoblastic leukemia (ALL) in the US.

220 Background: Personal costs of childhood cancer can contribute to disparities in health outcomes. The purpose of ACCL20N1CD is to examine trajectories of parental costs and the associated financial distress, cost coping behaviors, and household material hardships (HMH) during treatment for pediatric ALL. Objective is to report baseline characteristics of the parents and their households. Methods: The study used a prospective cohort design with repeated measures. Setting was Children’s Oncology Group (COG) practices at National Cancer Institute Community Oncology Research Program (NCORP) institutions. Parents who use English or Spanish, and have children newly diagnosed with ALL treated at COG NCORP practices were eligible. Parents were asked to complete surveys at 3 time points, including baseline (T1; during induction and <7 days after planned induction remission evaluation). Surveys included items about (a) parent socio‐economic status, financial distress measured by 8-item Personal Wellness Scale (PFWS), and cost coping behaviors, and (b) HMH. Factors related to high PFWS scores were evaluated by logistic regression. Results: Of 104 evaluable parents, most were female (83.7%), white (65.4%), non-Hispanic (48.1%), partnered (79.8%), > high school diploma (93.3%), used English (84.6%), worked full (48.1%) or part (5.8%) time, and paid for their child’s care with public insurance (57.7%). Median household income=$50,000 (Inter-Quartile Range/IQR 20,000-100,000) for 4 (IQR 4-5) people. Not including wages lost due to caregiving, out of pocket payments for medical care + other ALL-related costs in the prior month >15% of monthly income for 51.9% of households, which is considered financially catastrophic. 24.0% of households lacked food stability; 21% had housing insecurity. Conclusions: At baseline, sizeable proportions of parents exhibit high out of pocket costs, high financial distress level, and multiple cost coping behaviors with implications for future health and individual and household quality of life.

Transfusional hemosiderosis in childhood cancer patients and survivors.

Children treated for cancer are at risk for adverse effects of iron due to transfusions administered during prolonged marrow suppression, which may increase exposure to toxic forms of iron, extrahepatic iron accumulation, and long-term organ damage. This study aimed to characterize the severity and organ distribution of clinically significant, multisystem iron overload (IO) in an at-risk cohort of pediatric cancer patients. This was a retrospective, cross-sectional study of childhood cancer patients who underwent a magnetic resonance imaging (MRI) due to clinical concern for IO. Data regarding cancer type and treatment, transfusion history, MRI and laboratory results, and treatment for IO were collected. Severity of IO was analyzed by non-parametric tests with respect to clinical characteristics. Of the 103 patients, 98% of whom had a Cancer Intensity Treatment Rating (ITR-3) of 3 or higher, 53% (54/102) had moderate or greater hepatic siderosis, 80% (77/96) had pancreatic siderosis, 4% (3/80) had cardiac siderosis, and 45% (13/29) had pituitary siderosis and/or volume loss. Pancreatic iron was associated with both cardiac (p=.0043) and pituitary iron (p=.0101). In the 73 off-therapy patients, ferritin levels were lower (p=.0008) with higher correlation with liver iron concentration (LIC) (p=.0016) than on-therapy patients. Fifty-eight subjects were treated for IO. In this heavily treated cohort of pediatric cancer patients, more than 80% had extrahepatic iron loading, which occurs with significant exposure to toxic forms of iron related to decreased marrow activity in setting of transfusions. Further studies should examine the effects of exposure to reactive iron on long-term outcomes and potential strategies for management.

Autonomic Dysfunction Among Adult Survivors of Childhood Cancer in the St. Jude Lifetime Cohort Study

BackgroundThe burden and functional significance of autonomic dysfunction among survivors of childhood cancer is unknown. ObjectivesWe evaluated the prevalence, risk factors, and functional relevance of autonomic dysfunction in survivors. MethodsWe conducted a cross-sectional prospective evaluation of 1,041 adult survivors of childhood cancer treated with anthracyclines (31.1%), chest-directed radiation (13.5%), both (19.5%), or neither (35.9%), and 286 community control subjects enrolled in the SJLIFE (St Jude Lifetime Cohort Study). Four measures of autonomic dysfunction were evaluated: elevated resting heart rate, decreased heart rate reserve, decreased systolic blood pressure response to exercise, and delayed heart rate recovery. Logistic regression tested associations with impaired cardiorespiratory fitness (peak Vo2 < 80% predicted). ResultsSurvivors (50.7% female) were 9.0 ± 5.8 years at cancer diagnosis and 35.5 ± 8.9 years at evaluation. Prevalence (survivors vs control subjects) of elevated resting heart rate (17.9% vs 7.0%), decreased heart rate reserve (21.7% vs 9.1%), decreased systolic blood pressure response to exercise (25.3% vs 12.6%), and delayed heart rate recovery (24.3% vs 10.6%) was more than 2-fold higher among survivors (P < 0.001 for all). Carboplatin (adjusted OR: 2.50; 95% CI: 1.42-4.40; P = 0.001), chest-directed radiation therapy (adjusted OR: 2.06; 95% CI: 1.52-2.75; P < 0.001), and cranial radiation (adjusted OR: 1.49; 95% CI: 1.08-2.05; P = 0.015) were associated with an increased likelihood of having ≥2 measures of autonomic dysfunction. Survivors with ≥2 measures of autonomic dysfunction were at increased risk for impaired cardiorespiratory fitness (adjusted OR: 2.71; 95% CI: 1.82-4.02; P < 0.001). ConclusionsSurvivors of childhood cancer manifest a higher prevalence of autonomic dysfunction associated with impaired cardiorespiratory fitness.

Involving children and young people in supportive cancer care research: the value of FDS grant funding and charitable partnerships

INTRODUCTION Involvement of children and young people in research has a multitude of benefits for children, researchers and the quality of the research itself. Despite the benefits of involvement, this is not always completed or reported in practice. METHODS This paper looks at the involvement of children and young people during a research study exploring the acceptability of photobiomodulation for mucositis management. It considers the importance of costing involvement into grant funding, and the value of charitable partnerships in conducting research with patient and public involvement. RESULTS Children and young people with experience of cancer, and their parents, were involved at the stages of grant application, research design, data analysis and dissemination. Involvement of families resulted in changes to inclusion criteria, plain language summaries and participant information documents. They provided insight into data analysis, and designed and filmed co-created video outputs to support acceptability of the treatment, dissemination of the research and research involvement of other children. Involvement was supported both practically and financially by charitable partnership with the Candlelighters children’s cancer charity as well as research grant funding from the Royal College of Surgeons of England’s Faculty of Dental Surgery. CONCLUSIONS Child and parent contributors shaped the research project, resulting in changes to the study design, data analysis and co-creation of video resources. Charitable partnership and flexibility of involvement supported diversity in the context of paediatric cancer research. Researchers should consider what they can contribute in return to child contributors and charities who provide support.

Effects Of An Exercise Program On Bone Health In Pediatric Cancer Survivors: Randomized Controlled Trial

Effects Of An Exercise Program On Bone Health In Pediatric Cancer Survivors: Randomized Controlled Trial

The regional cancer spectrum in Uganda: a population-based cancer survey by sub-regions (2017-2020).

Accurate estimation of the burden of cancer in developing countries is a major public health concern for cancer prevention and control because of the limited coverage of population-based cancer registries (PBCRs). The cancer registration coverage status of Uganda was 11.90% and was not uniformly distributed in all regions of Uganda. This population-based survey was conducted to assess the burden of cancer in all the sub-regions of Uganda by site, sex and age group to accurately determine the cancer profile of Uganda by sub-region for a tailored intervention to mitigate cancer risk factors and burden. This study used existing administrative units of Uganda from which 55 districts emerged, forming 10 sub-regions as satellite population-based cancer registry study sites. Data on newly diagnosed cancer cases were retrospectively collected for the period 2017-2020 using a cancer notification form, entered into CanReg5 Software, exported to spreadsheets and univariate analysis was performed to determine the cancer spectrum, their proportions and crude rates by site, sex, age group and geographical location. A total of 25,576 cancer cases were registered, up to 14,322 (56%) were in females and, male cancers were 11,254 (44%). The top five female cancers in all the sub-regions included cervical cancer (43%, n = 6,190), breast (22%, n = 3,200), esophagus (5.6%, n = 800), ovary (5.2%, n = 746), Kaposi Sarcoma (KS) (4.7%, n = 666) and other less common cancers (18.5%, n = 2,720). In males, the top five cancers included prostate cancer 25.1 % (n = 2,820), esophagus 15.1% (n = 1,704), KS 12.4% (n = 1,395), liver 8.8% (n = 989) and stomach 4.8% (n = 539), with other less common male cancers accounting for 33.8% (n = 3,807).In all the sub-regions of Uganda, cancers of the esophagus, liver and KS are common in both males and females, but the number of males with these cancers is twice that of their female counterparts. In Rwenzori, Kigezi and Bugishu sub-Regions, there seems to be an increased risk of developing other skin cancers in females, while stomach cancers have been reported in both males and females. Most of the other sub-regions register emerging cases of only ovarian cancer in females. In children, the top three cancers included lymphoma, 33.9% (n = 653); soft tissue sarcomas, 20.8% (n = 400); malignant bone tumors, 15.8% (n = 305); myeloid-type leukemia, 13.8% (n = 265); and the other less common childhood cancers combined, 15.7% (n = 303). The proportion of childhood cancers is higher in the male child compared to the female at a ratio of 1.3:1. The sub-regional cancer spectrum in Uganda ranges from cervical cancer to breast, esophageal, ovarian and KS in females. Male cancers include prostate, esophageal, KS, liver and stomach cancers. Although the cancer profile is similar in most sub-regions of Uganda, except Ankole subregions with mountainous topography (Rwenzori, Kigezi, Bugisu), there has been significant variation in cancer profile, especially for males, where Non-Hodgkins Lymphomas is one of the cancers reported for Uganda by PBCRs in Gulu, and Kampala has been replaced by stomach cancers as one of the common male cancers in the sub-regions. These findings emphasize the need for the establishment and support of additional regional PBCRs and periodic population-based cancer surveys to accurately determine the burden of cancer, inform the establishment of regional cancer centers and guide national and sub-national cancer control programs in Uganda. Cancer surveillance systems using PBCRs should be part of the national cancer control program. Periodic population-based cancer surveys should also be conducted as part of Uganda's demographic and health surveys in areas without PBCRs to inform the country comprehensively and accurately on the cancer burden to design robust cancer mitigation measures.

Chemotherapy-Induced Febrile Neutropenia Managed on an Outpatient Basis at the Pediatric Hematology and Oncology Department of the Ibn Sina Children’s Hospital in Rabat

Introduction: Febrile neutropenia (FN) is an important cause of morbidity and mortality in patients with cancer. The general objective of this study was to collect data and analyze the factors influencing management of the febrile neutropenia at the day hospital at the pediatric department of Hematology and Oncology (SHOP) of Rabat.

Association Between Medicaid Coverage Continuity and Survival in Patients With Newly Diagnosed Pediatric and Adolescent Cancers.

Many patients with cancer do not gain Medicaid coverage until a cancer diagnosis, which can reduce access to early cancer detection and timely treatment, potentially driving inferior survival. Little is known about whether continuous Medicaid coverage prediagnosis through postdiagnosis (v gaining Medicaid at/after diagnosis) provides survival benefits for pediatric/adolescent oncology patients. We identified patients newly diagnosed with cancer at age 21 years or younger in a large pediatric health system between 2007 and 2016. Electronic medical records (EMRs) were linked to Medicaid administrative data to differentiate insurance continuity patterns during the 6 months preceding through the 6 months after cancer diagnosis (assessment window): continuous Medicaid, newly gained Medicaid (at or after diagnosis), and other Medicaid enrollment patterns. For patients not linked to Medicaid data, we used EMR-reported insurance types at diagnosis. We followed patients from 6 months postdiagnosis up to 5 years, death, or December 2020, whichever came first. Multivariable regressions estimated all-cause and cancer-specific survival, controlling for sociodemographic and cancer-related factors. Among 1,800 patients included in the analysis, 1,293 (71.8%) had some Medicaid enrollment during the assessment window; among them, 47.6% had continuous Medicaid and 36.3% had newly gained Medicaid. Patients not linked with Medicaid data had private (26.9%) or other/no insurance (1.2%) at diagnosis. Compared with patients with continuous Medicaid, those with newly gained Medicaid had higher risks of all-cause death (hazard ratio [HR], 1.41 [95% CI, 1.10 to 1.81]; P = .008) and cancer-specific death (HR, 1.46 [95% CI, 1.12 to 1.90]; P = .005). Continuous Medicaid coverage throughout cancer diagnosis is associated with survival benefits for pediatric/adolescent patients. This finding has critical implications as millions of American individuals have been losing coverage since the unwinding of the Medicaid Continuous Enrollment Provision.

Assessment of cancer predisposition syndromes in children with leukemia and solid tumors: germline-genomic profiling and clinical features in a series of cases

Cancer predisposition syndromes (CPS) are a group of genetic disorders that increase the risk of various cancers. Identifying CPS has a significant impact on the treatment plan, screening and follow-up strategy, and genetic counseling of the family. However, in children, it goes underdiagnosed in most clinical setups, especially in low- and middle-income (LMIC) countries. In the present study, we screened 60 pediatric oncology patients for a possible CPS based on pre-defined selection criteria. Six patients met the criteria, three of whom had hematological malignancy, while the remaining three had sarcoma. Whole exome sequencing was performed in the selected patients to confirm the diagnosis. Germline mutation in CPS-related genes was discovered in five of six cases, including novel mutations discovered in two. An adverse outcome was observed in all five patients with underlying cancer predisposition syndrome, with three having relapsed and two having progressive disease. Our study reflects a prevalence of 10% underlying CPS in a limited cohort of patient based on the phenotype-genotype approach in our cohort. Using pre-defined clinical selection criteria, screening can be directed to a high-risk patient cohort with high-pick up rate for CPS. The selection criteria could be utilized in any LMIC-based clinical setup for pediatric cancer patients who may benefit from modification of treatment as well as genetic counseling.

Effect of Smart Pill Box on Improving Adherence to 6-Mercaptopurine Maintenance Therapy in Pediatric ALL

Abstract Introduction 6-Mercaptopurine (6-MP) forms the backbone of maintenance chemotherapy for acute lymphoblastic leukemia (ALL). A Children's Oncology Group study found 3.9-fold increased risk of relapse in children with 6-MP adherence less than 90%. Objective This article estimates the impact of smart pill box in improving adherence to 6-MP during maintenance phase chemotherapy in children with ALL. Material and Methods It is a prospective interventional study done at pediatric oncology clinic of a tertiary care hospital. Participants being 40 newly diagnosed children with ALL. Baseline adherence was assessed and impact of smart pill box was estimated after using it for 60 days. Subjective and objective assessment of baseline adherence and adherence after intervention was done by subjecting the parents of the children to Morisky Medication Adherence Score 8 (MMAS-8) and measurement of patient's red blood cells (RBC) 6-MP metabolites (6-thioguanine [TGN] and 6-methylmercaptopurine [MMP]) levels, respectively, pre- and postintervention. Results The mean age was 7.39 ± 4.29 years. NUDT15*3 polymorphism was present in 10.26%, and none had TPMT polymorphism. Baseline assessment of adherence to 6-MP by MMAS-8 revealed low, medium, and high adherence in 7.5, 35, and 57.5%, respectively. Baseline 6-TGN and 6-MMP levels by cluster analysis revealed poor adherence in 10%. Following intervention, mean MMAS-8 improved from 7.34 ± 0.78 to 7.66 ± 0.55 (p-value &lt; 0.015) and the median 6-TGN level improved from 150 to 253 pmol/8 × 108 RBCs (p-value &lt; 0.001). Conclusion Nonadherence to 6-MP is widely prevalent in Indian children. Simple measures like smart pill box can improve adherence.
