Objective: Pediatric posterior fossa tumors pose diagnostic challenges due to their diverse histopathological features and variable clinical presentations. Conventional magnetic resonance imaging (MRI) serves as the initial diagnostic tool; however, additional modalities, such as diffusion-weighted imaging (DWI), are essential for refining tumor classification. This retrospective single-center study aimed to evaluate the diagnostic utility of apparent diffusion coefficient (ADC) parameters in distinguishing between the most common pediatric posterior fossa tumors. Materials and Methods: Fifty-nine patients under the age of 18 (27 females and 32 males) with histopathologically diagnosed primary posterior fossa tumors underwent pre-treatment conventional and diffusion MRI. Apparent diffusion coefficient values were measured from solid tumor regions and normal cerebellar parenchyma, with subsequent calculation of tumor/normal cerebellar ADC ratios. Results: The median ADC values for pilocytic astrocytomas (PAs) were 1786.2 ×10−6 mm² /s, ependymomas 1144.9 × 10−6 mm² /s, and for medulloblastomas 666.1 × 10−6 mm2 /s were significantly different (P < .001 for all three). Similarly, the median ADC ratios demonstrated discriminatory potential, with PAs showing the highest ratio (2.46), followed by ependymomas (1.55) and medulloblastomas (0.89) (P < .001 for all three). Receiver operating characteristic analysis revealed distinct ADC cutoffs and ratios for differentiating all tumor types from each other. Conclusion: Despite limitations, such as a small cohort size and different MRI protocols, our results show that ADC metrics are especially useful for distinguishing between the most common pediatric posterior fossa tumors. We recommend that future studies integrate advanced imaging techniques and larger cohorts to improve diagnostic accuracy. [ABSTRACT FROM AUTHOR]

ABSTRACT: Aims: This study aims to review our experience of treating ovarian masses in children with an emphasis on clinical presentation, diagnosis, treatment, and outcome. Methods: We retrospectively reviewed the electronic medical records of all patients below 18 years of age who underwent surgical treatment for ovarian masses at our institute between 2009 and 2023. Study variables included demography, clinical presentation, physical findings, tumor markers, radiologic features, operative details, histopathology, follow-up status, and overall survival. Results: During the study period, 30 patients with a mean age of 10.07 years (range: 15 days–18 years) underwent surgical treatment for ovarian masses. Nonneoplastic ovarian masses were seen in 5 (16.7%) patients, whereas 25 (83.3%) patients had benign (10 [33.3%], borderline 3 [10%], or malignant 12 [40%]) ovarian neoplasms. The most common clinical presentation in the benign group was abdominal pain (n = 6), whereas painless abdominal mass (n = 6) was the predominant complaint in children with malignant tumors. A functional ovarian mass presenting with precocious puberty or virilization was seen in 5 (16.7%) patients. On imaging, nonneoplastic and benign lesions had a mean size of 4.33 (range: 3.1–6) cm and 12.63 (range: 2.8–28) cm, respectively, whereas borderline and malignant masses had a mean tumor size of 22.5 (range: 6.5–32) cm and 12.55 (range: 3.5–18.7) cm, respectively (P < 0.05). The cystic component was identified in all nonneoplastic and benign tumors, whereas the solid component was present in all borderline and malignant lesions (P < 0.05). Tumor markers such as serum alpha-fetoprotein and beta-human chorionic gonadotropin were raised in 8 (66.67%) of malignant tumors, whereas markers were normal in all benign lesions and borderline malignant lesions and 4 (33.33%) of malignant tumors. Lactate dehydrogenase (LDH) was also raised in all malignant masses (n = 12), whereas it was normal in all benign and borderline malignant masses (n = 18). In 6 (20%) patients with nonneoplastic and benign masses with maximum tumor size <6 cm, the laparoscopic approach was adopted, whereas open surgery was preferred in the rest of the patients. At a mean follow-up of 53.5 (range: 4–117) months, all patients are alive and disease free. Conclusions: Preoperative imaging characteristics (tumor size and solid component) and raised tumor markers may help us to differentiate between benign and malignant ovarian pathologies. The overall prognosis of pediatric ovarian tumors seems to be favorable. [ABSTRACT FROM AUTHOR]

Simple Summary: Proton beam radiation therapy is one of the major treatment modalities used for cancer treatment, including brain tumors. This treatment modality is distinct from other radiation options because of its ability to deliver radiation to tumor targets while sparing healthy tissue. Brainstem toxicity is a rare but important complication can arise due to exposure to radiation; hence, in this systematic review and meta-analysis, we aimed to explore the risk of brainstem toxicity in pediatric brain tumor patients undergoing proton beam radiation, focusing on quantifying its incidence and severity. Eleven articles were considered eligible in our study, and the results yielded an overall brainstem toxicity incidence of 1.8%, ranging in severity, with Grade 1 brainstem toxicity (asymptomatic) being the most common. This study revealed a low incidence of symptomatic brainstem toxicity and related mortality among pediatric brain tumor patients undergoing proton beam radiation, which could support the idea of it having a good toxicity profile and possibly re-enforces the need for more comprehensive primary studies regarding this radiation modality in brain tumor patients to uncover unknowns and help us understand the grey areas of this topic. Background: Proton beam radiation therapy (PBRT) is an advanced cancer treatment modality that utilizes the distinctive physical properties of protons to precisely deliver radiation to tumor targets while sparing healthy tissue. This cannot be obtained with photon radiation. In this systematic review and meta-analysis, we aimed to comprehensively assess the risk of brainstem toxicity in pediatric brain tumor patients undergoing PBRT. Methods: With adherence to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, a predetermined search strategy was used to identify eligible articles from PubMed, Web of Science, Scopus, and Cochrane Library through July 2024. Results: The current study included a total of 11 eligible articles. The pooled prevalence of patients who suffered from brainstem toxicity was 1.8% (95% CI: 1%, 2.6%). The pooled prevalences of patients with Grade 1 to Grade 5 brainstem toxicity were found to be 10.6% (95% CI: 8.8%, 30%), 1.5% (95% CI: 0.6%, 2.5%), 0.7% (95% CI: 0.3%, 1.1%), 0.4% (95% CI: 0.1%, 0.7%), and 0.4% (95% CI: 0.1%, 0.8%), respectively, with an overall pooled prevalence of 0.7% (95% CI: 0.4%, 1%). Conclusions: This study revealed a relatively low incidence of symptomatic brainstem toxicity and its related mortality in the pediatric population undergoing PBRT. However, further research is encouraged to study the broader effects of PBRT and to explore various factors that may influence the risk of brainstem toxicity in patients treated with PBRT.

PURPOSE Pediatric lung tumors are primarily discussed in the surgical literature. However, limited research has been reported on their imaging findings, and only a few tumor types have been documented. Therefore, the aim of this article is to describe the imaging features of primary lung tumors in children. METHODS The archives of the pediatric radiology unit were reviewed for primary lung tumors documented between 2007 and 2023. In total, 24 patients (9 girls and 15 boys; aged 5 months to 16 years) were included in the study. Their demographic characteristics, clinical presentation, and histopathologic results were obtained. All imaging studies were reviewed by two radiologists for various findings (e.g., lymphadenopathy, atelectasis, pleural effusion, calcification, multiplicity, pneumothorax, axial and lobar location, laterality, tumor margin, mediastinal shift, contrast enhancement pattern, signal intensity on T1- and T2-weighted images, and diffusion pattern), and a final decision was made by consensus. The mean tumor size was compared between the benign and malignant groups using a t-test. RESULTS There were 15 (62.5%) benign tumors, as follows: inflammatory myofibroblastic tumor (IMT; n = 10, 41%), hemangioma (n = 2, 8%), pneumocytoma (n = 2, 8%), and mature cystic teratoma (n = 1, 4%). Moreover, there were 9 (37.5%) malignant tumors, as follows: pleuropulmonary blastoma (PPB; n = 6, 25%), adenocarcinoma (n = 2, 8%), and lymphoepithelioma-like carcinoma (LELC) (n = 1, 4%). The most frequently reported symptoms were cough, fever, dyspnea, chest pain, and recurrent infection; six patients reported no clinical symptoms. Fifteen tumors (62%) were located in the right lung. The mean tumor diameter at the time of diagnosis was 6.4 ± 3 cm (benign group: 6.7 ± 3.4 cm; malignant group: 6 ± 2.3 cm, P > 0.050). Calcification was present in 80% of the patients with IMT. At the time of diagnosis, two (8.3%) patients were found to have metastasis: one was diagnosed with adenocarcinoma and the other with LELC. Tumors were located peripherally in 18 (75%) patients. CONCLUSION The symptoms associated with lung masses are non-specific. There is no correlation between tumor size and malignancy. The most common tumors observed in this study were IMT and PPB, respectively. IMT is highly associated with calcification. CLINICAL SIGNIFICANCE Primary lung tumors are rarely seen in children, and they have different histopathological types. Calcification might be an important radiological clue for the diagnosis of IMT, which is the most common lung tumor in children. [ABSTRACT FROM AUTHOR]

Background: Robot-assisted surgery (RAS) is being performed with increasing frequency in pediatric oncology. We report our experience with RAS for renal tumors in children and compare the outcomes between RAS and laparoscopic surgery (LAS). Methods: A total of 23 patients with renal tumor who underwent minimally invasive surgery (MIS) between January 2020 and December 2023 were included in the study. The inclusion criteria enrolled in this study was unilateral tumors with maximum tumor diameter less than 10 cm. Patients who had enlarged lymph node, venous thrombosis, preoperative tumor rupture, bilateral renal tumor, or extrarenal extension on imaging were deemed contraindications and excluded. Patient demographics, operative details, postoperative outcomes and follow-up were recorded. Results: Among these patients, 17 underwent RAS and 6 underwent LAS. In the RAS group, the median age was 64 months (range, 9–156) with a median weight of 19.48 kg (range, 8.4–46.5); the maximum tumor diameter at operation was 55.65 mm (range, 22–88); the operation time was 188.8 min (range, 120–210), the intraoperative blood loss was 20 ml (range, 5–50), and the length of postoperative hospital stay was 4 days (range 1–9). There was no significant difference in patients' age, weight, location, tumor size, histological pattern and operation time between the two groups (P > 0.05). The RAS group had a significantly less intraoperative blood loss (P = 0.026) and less length of postoperative stay (P = 0.01) than the LAS group. Conclusion: Our initial experience suggested that RAS in pediatric renal tumor was feasible and safe, and it reduced surgical trauma and accelerate postoperative recovery for the patients. Due to the limitations of sample size and study quality, the clinical importance of these findings still needs to be further verified. [ABSTRACT FROM AUTHOR]

Simple Summary: Appendiceal neuroendocrine neoplasms are very rare in pediatric populations; thus, there are no common guidelines or consensus for the management in children and adolescents, and adult protocols are usually adopted. In the present study, we report on 17 patients that underwent appendectomy for appendicitis with incidental diagnosis of a neuroendocrine tumor revealed upon histologic examination. Patients' characteristics, tumor histology, follow-up and outcome are described and compared to data from the literature, with similar results being reported in various studies. Analysis of previous scientific publications on children with appendiceal neuroendocrine neoplasms was performed and recommendations for treatment and follow-up were reviewed. This tumor displays benign behavior and an excellent outcome in children and adolescents; thus, many authors agree that aggressive surgery after the patient's first appendectomy is not necessary and follow-ups can be reduced. Background/Objectives: Appendiceal neuroendocrine neoplasms (ANENs) are usually found incidentally during histology examination after appendectomy for appendicitis. Due to their rarity in pediatric populations, there is no consensus on treatment or follow-up. The analysis of patients with ANENs of our and other studies will increase the understanding of this tumor. Methods: Pediatric patients with ANENs were uniformly managed at our center between 1998 and 2023. Patients' presenting symptoms, surgery, tumor histology, post-surgical work-up, follow-up and outcome were analyzed. Results: Our report describes 17 patients with a diagnosis of ANEN after appendectomy. The median age was 14 years (range of 4–17 years). Tumors were located at the tip of the appendix in 58.8% of cases and only one had a diameter >1 cm. All were well-differentiated tumors with free resection margins. The submucosa was invaded in five cases, muscularis propria in eight and subserosa in four. Post-appendectomy work-up included tumor marker measurement, abdominal ultrasound and computed tomography or magnetic resonance imaging, chest X-ray and octreotide scintigraphy. No residual tumors or metastases were detected. Additional surgery was not necessary. Follow-up was carried out for a median duration of 6 years (range of 1–10 years). Only one patient was lost to follow-up and all other patients are alive without tumor recurrence. Conclusions: The tumor characteristics of our patients confirmed data from the literature. With the lack of a sufficient number of large prospective trials, it is important to add more information to confirm the benign nature and excellent outcome of this tumor, even without additional surgery. Consensus guidelines are needed for ANENs in pediatric populations. [ABSTRACT FROM AUTHOR]

Background: The number of children diagnosed with cancer is expected to increase by 2050. The caring aspect of these children is usually left to members of the family, more so the mothers. Caregivers are usually faced with various challenges, such as financial issues, social stigma, and emotional and psychological issues. Caregivers use various coping strategies to manage the challenges they experience in the caring process, which can be positive or negative coping strategies. Objective: To explore the challenges and coping strategies of caregivers of children with cancer receiving care at a national referral hospital in Kenya. Methods: This study employed a descriptive phenomenological approach to explore the challenges and coping strategies of caregivers of children with cancer receiving treatment at a national referral hospital in Kenya. Purposive and snowball sampling techniques were used to select 44 participants for five focus group discussions (FGDs) conducted between October and December 2023. The data were analysed via inductive thematic analysis. Results: Four themes arose from the challenges experienced, which included psychological, financial, treatment-related, and social/family-related issues. These eleven subthemes included stress, depression, lack of transport, lack of food, loss of employment, treatment delays, and marital issues, among others. Two themes related to coping strategies were positive adaptation and denial, which were highlighted as negative coping strategies. Positive coping included praying, crying, talking to people, and seeking help. Conclusion: Caregivers of children with cancer undergo various challenges and apply various coping strategies to try and adapt to their new normal. Reinforcing positive coping strategies and helping caregivers utilize other coping strategies, such as the use of support groups, could help them better care for their children.

This study aimed to determine the predictive power of religious coping of parents of children with cancer on caregiver burden, depression, anxiety, and stress in Turkey. It was designed as a descriptive and cross-sectional study, utilizing correlational analysis and regression models to explore associations between variables. Data were collected from 164 parents in the pediatric hematology-oncology clinics of a university hospital between November 2023 and March 2024. There was a negative correlation between caregiver burden score and negative and positive religious coping scores. Caregiver burden scores were positively correlated with depression, anxiety, and stress scores. Results indicated that caregiver burden, education level, employment status, family structure, family income, and age at diagnosis significantly predicted positive religious coping. For negative religious coping, caregiver burden, education level, family structure, and family income were significant predictors. This suggests that religious coping may help reduce caregiver burden, underscoring the importance of promoting constructive coping strategies to support caregivers' well-being.

Background: The primary objective was to measure adherence to clinical practice guideline (CPG) recommendations for fertility preservation (FP) in pediatric cancer patients treated in National Cancer Institute Community Oncology Research Program (NCORP) sites. Secondary objectives were to describe factors such as site size associated with CPG-inconsistent care delivery and cryopreservation completion. Methods: This retrospective, multicenter study included patients 15 to 21 years old with a first cancer diagnosis from January 2014 through December 2015 who were previously enrolled to a Children's Oncology Group (COG) study and received care at a participating NCORP site. Patients were randomly selected from a list generated by the COG for chart review by participating sites. Primary outcome was care delivery that was inconsistent with a strong CPG recommendation on FP, namely discussion and offering of FP options before cancer treatment initiation, as adjudicated centrally by a panel. Results: A total of 129 patients from 25 sites were included. Among these, 48% (62/129) received CPG-inconsistent care. Most CPG-inconsistent care was due to lack of FP discussion documentation (93.5%, 58/62). Small site size, treatment at a pediatric (vs mixed adult/pediatric) site, and female sex were associated with higher odds of CPG-inconsistent care delivery. Conclusions: Newly diagnosed pediatric cancer patients often received CPG-inconsistent care for FP, with disproportionate gaps noted for females, and those treated at smaller or pediatric NCORP sites. The primary reason for CPG-inconsistent care is lack of FP discussion from clinicians. Opportunities to improve FP CPG implementation are highlighted. [ABSTRACT FROM AUTHOR]

Purpose: The purpose of the study was to answer the following questions. What was functional results of pediatric patients receiving a short stem allograft-prosthesis composite of the proximal femur? What was complication rate and revision-free implant survival? Was it possible to preserve the bone stock of the proximal femur in pediatric patients? Methods: We reviewed 10 pediatric patients treated with proximal femur resection for a primary bone tumor and reconstruction with short stem allograft-prosthesis composite, with at least 24 months follow-up. The median age was 9 years (4–13) at surgery. The mean resection length was 15 cm (6–29). In six cases, fixation was performed with a short plate positioned under the great trochanter while in four cases a long plate extended over the great trochanter was employed. Results: Nine complications that required surgical revision were assessed in six patients (one wound dehiscence, two nonunions, two fractures, one acetabular wear, three hypometria), while allograft-prosthesis composite removal was required in three patients. The revision-free survival was 57% (95% confidence interval 33%–100%) at 5 and 10 years. The graft removal-free survival was 75% (95% confidence interval 50%–100%) at 5 and 10 years. The mean Musculo-Skeletal Tumor Society Score was 28 (20–30). Conclusions: Allograft-prosthesis composites with short stem and compression plate represents an effective reconstructive option after proximal femur resection for primary bone tumors in growing patients, preserving bone stock. The use of a compression plate extended over the greater trochanter seemed to reduce failure rate. [ABSTRACT FROM AUTHOR]

Background: A child's cancer is a highly stressful experience for the entire family. Childhood cancer disrupts family functioning and is one of the most stressful and challenging events parents face, often beyond their control. Parents play a crucial role in providing emotional support to children throughout their illness, and their ability to cope can help reduce the child's negative emotions. The aim of this study was to assess the prevalence of anxiety and depression among parents of children with cancer. Methods: This cross-sectional study followed the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) guidelines and included parents of children undergoing cancer treatment. Convenience sampling was used. The Beck Depression Inventory and the Hospital Anxiety and Depression Scale were utilized to assess the parents. Results: This study included 270 participants (73% women, 27% men) with children at an average age of 8.75 ± 4.82 years. Diagnoses included leukemia (53%), lymphoma (29%), and other cancers. On the Beck Depression Inventory, 33% of parents were mildly depressed, 12% moderately depressed, and 32% severely depressed, with an average score of 20.63 ± 12.39 points. The HADS-M scale indicated anxiety at 48.43 ± 20.78%, depression at 45.01 ± 22.8%, and aggression at 54.72 ± 28.71%. Conclusions: Most parents of children with cancer have symptoms of depression and anxiety, which are influenced by the duration of the child's illness. A strong correlation was observed between the level of anxiety and the tendency for depression. [ABSTRACT FROM AUTHOR]

Simple Summary: Patient activation is a very important psychological construct to examine in individuals who have chronic conditions, because it assesses the one's confidence in managing their own health and care. For childhood cancer survivors, continued follow-up is imperative to monitor late effects conditions; yet many do not adhere to surveillance guidelines. Therefore, investigating this construct could highlight risk factors in the population that contribute to low activation. Furthermore, examining the long-term impact of patient activation on psychological health as well as its contribution to health behavior could provide a reasonable target for interventions to enhance health outcomes in survivors. Background: Patient activation describes a willingness to take action to manage health and is associated with health outcomes. The purpose of this study was to characterize patient activation and its association with psychological outcomes and health behaviors in childhood cancer survivors. Methods: Participants were from the St. Jude Lifetime Cohort Study (SJLIFE). Activation levels (1–4, 4 = highest activation) were measured with the Patient Activation Measure (PAM). Psychological outcomes and health behaviors were obtained via self-report. Cognitive function was assessed by trained examiners. ANOVA or chi-squared tests were utilized to assess group-level differences in activation. Multivariable regression models were used to assess associations between PAM scores and outcomes of interest. Results: Among 2708 survivors and 303 controls, more survivors endorsed lower activation levels than the controls (11.3 vs. 4.7% in level 1) and fewer survivors endorsed the highest level of activation than the controls (45.3 vs. 61.5% in level 4). Not endorsing depression (OR: 2.37, 95% CI 1.87–2.99), anxiety (OR: 2.21, 95% CI 1.73–2.83), and somatization symptoms (OR: 1.99, 95% CI 1.59–2.50), general fear (OR: 1.45, 95% CI 1.23–1.71) and body-focused (OR: 2.21, 95% CI 1.83–2.66), cancer-related worry, and physical (OR: 2.57, 95% CI 2.06–3.20) and mental (OR: 2.08, 95% CI 1.72–2.52) HRQOL was associated with higher levels of activation. Lower activation was associated with not meeting physical activity guidelines (OR: 2.07, 95% CI 1.53–2.80). Conclusions: Survivors endorsed lower activation levels than peers. Interventions to improve physical and psychological health outcomes could leverage these results to identify survivors who benefit from support in patient activation. [ABSTRACT FROM AUTHOR]

Simple Summary: Acupuncture is becoming a popular complementary treatment in pediatric cancer care for managing symptoms like nausea and vomiting that result from cancer treatments. This review aims to evaluate how effective and safe acupuncture and similar techniques are for children with cancer. By analyzing data from multiple studies, the authors found that acupuncture may help reduce nausea and vomiting in young cancer patients. However, there is not enough evidence to make conclusions about its effects on number of vomiting episodes, need for anti-nausea medication, or fatigue. More high-quality research is needed to confirm these benefits and ensure the safety of acupuncture for children undergoing cancer treatment. Background/Objectives: Oncology acupuncture is emerging as a complementary treatment in pediatric cancer care centers. It is valued for its potential to manage symptoms associated with cancer and treatment toxicities without increasing polypharmacy. The aim of this review is to evaluate the efficacy and safety of acupuncture and related techniques in alleviating symptoms of cancer treatment in pediatric oncology patients. Methods: A comprehensive search was conducted across nine databases, including PubMed, Cochrane Library, and CNKI, up to June 2023. Inclusion criteria focused on randomized and quasi-randomized controlled trials involving pediatric oncology patients undergoing needle acupuncture or related techniques. Study selection and data extraction were independently performed by pairs of authors. Results were analyzed narratively, and meta-analysis was performed when possible. Results: Results suggest that acupuncture may help manage symptoms such as nausea and vomiting in pediatric oncology patients. However, the quality of evidence was generally low, and further research is required to substantiate these findings. Conclusions: Acupuncture shows promising results as a complementary treatment for reducing nausea and vomiting in pediatric oncology. However, current evidence is insufficient to draw conclusions for other outcomes, such as the number of vomiting episodes, reduction in antiemetic medication use, or fatigue. High-quality, rigorously designed studies are necessary to better understand the clinical relevance and safety of acupuncture in this vulnerable population. [ABSTRACT FROM AUTHOR]

Aim: Childhood cancer survival has improved significantly with advances in multimodal treatment. However, treatment-related long-term side effects, including dental developmental abnormalities, remain a concern. The aim of this study was to investigate permanent tooth development and associated risk factors in childhood cancer survivors who were treated before the age of six years, focusing on non-leukemia cases. Materials and Methods: This study was conducted on childhood cancer cases treated with chemotherapy and/or radiotherapy at a single center. Patients diagnosed before the age of six and who were twelve or above at the time of assessment were included. Dental examinations, including Decayed, Missing, Filled Teeth index and radiographic assessments, were performed. Statistical analyses were performed in order to identify associations between treatment modalities and dental findings. Results: Of 914 patients, 90 met the inclusion criteria, with 35 participating in this study. The mean age at diagnosis was four years, with a mean follow-up duration of ten years. Root shortening, hypoplasia, and hypodontia were observed to be common dental anomalies. There was a significant association between alkylating agents, vinca alkaloid plus alkylating agents and root shortening (p<0.001, p<0.001). No significant differences in dental findings were found based on gender, tumor site, or other treatment modalities (p<0.05). As the age at diagnosis increased, the risk of root shortening (p=0.026) and the frequency of hypodontia significantly increased with the duration after diagnosis (p=0.048). Conclusion: Childhood cancer survivors treated during early dentition periods are at risk of dental developmental anomalies, with alkylating agents showing the most significant impact. This emphasizes the necessity of providing these patients and their families with information on the importance of maintaining oral and dental health during and after cancer treatment.

Objective: Differentiated thyroid cancer (DTC) is the most common pediatric endocrine cancer but studies are scarce. Latest recommendations advocate for an individualized risk-based approach to select patients for additional therapy. Lymphovascular invasion is not considered, despite being a well-known risk factor in the adult population. The aim of this study was to describe the outcomes of a cohort of DTC patients diagnosed at pediatric age and to evaluate the impact of lymphovascular invasion on the risk of persistence/ recurrence. Methods: A retrospective study of patients diagnosed with DTC at pediatric age from 2010 to 2022 at a single center was performed. All patients had total thyroidectomy. Radioactive iodine therapy (RAI) was used in selected patients. The response to therapy and occurrence of persistent/recurrent disease were evaluated. Results: A total of 21 DTC were diagnosed, mostly papillary thyroid carcinoma (PTC) (81.0%, n=17). Six patients (28.6%) had nodal involvement and one (4.8%) had lung metastasis at the time of the diagnosis. Lymphovascular invasion was present in 11 patients (52.4%). After surgery, 13 patients (61.9%) underwent RAI. The mean follow-up time was 5.7±3.1 years. In total, 6 patients (31.6%) experienced persistent/recurrent disease during the follow-up time. Among PTC patients, persistent/recurrent disease was more frequent in the presence of lymphovascular invasion [55.6% (5/9) vs. 0.0% (0/6), p=0.031]. Conclusion: An individualized risk-based approach is recommended. Our study suggests that lymphovascular invasion may be associated with a higher risk of persistence/recurrence and should therefore be considered for decision making in children and adolescents with PTC.

Objective: The survival rates of children with acute lymphoblastic leukemia (ALL) have improved over the years, but infections remain a significant cause of morbidity and mortality. Chemotherapy has a range of harmful side effects including the loss of protective antibodies against vaccine-preventable diseases. The objective of this study was to evaluate the serological status of pediatric ALL cases before and after intensive chemotherapy. Materials and Methods: Children treated and followed for ALL at Dokuz Eylül University were included in this retrospective crosssectional study. Antibody levels against hepatitis A, hepatitis B, and rubella were routinely assessed at both the time of diagnosis and 6 months after completion of chemotherapy. Measles, mumps, and varicella antibody levels were evaluated at only 6 months after treatment. Results: Seventy-eight children who completed chemotherapy for ALL were enrolled in the study. All participants had non-protective antibody levels for at least one of the diseases. The highest seropositivity rate was found for hepatitis A (55.1%) and the lowest for measles (17.9%) after chemotherapy. Overall, 50.7%, 30.6%, and 45.7% of the patients significantly lost their humoral immunity against hepatitis B, hepatitis A, and rubella, respectively. Patients in the higher-risk group for ALL had lower seropositivity rates than patients of the other risk groups. There were statistically significant relationships between the protective antibody rates for hepatitis A and varicella and the ages of the patients. Except for hepatitis A vaccination, pre-chemotherapy vaccination did not affect post-chemotherapy serology. On the other hand, all children with a history of varicella before diagnosis showed immunity after chemotherapy. Conclusion: Patients with ALL, including those previously fully vaccinated, are at great risk of infection due to the decrease in protective antibody levels after chemotherapy. There is a need for routine post-chemotherapy serological testing and re-vaccination based on the results obtained. [ABSTRACT FROM AUTHOR]

Background: Timely and relevant information helps parents to cope when a child is diagnosed with cancer. However, obtaining and understanding information is not a straightforward process for parents. Objectives: This article aims to explain paediatric cancer parents' information behaviour related to the care of their child. Methods: Qualitative in‐depth interviews were conducted with fourteen Malaysian paediatric cancer parents and eight healthcare professionals who worked with paediatric cancer patients. Reflexivity and inductive approaches were used to interpret the data to identify meaningful themes and subthemes. Results: Three themes about how paediatric cancer parents interact with information emerged: Acquiring information, internalising information, and using information. Information may be actively sought or passively acquired. Cognitive and affective aspects influence how information is internalised into meaningful knowledge. Knowledge then leads to further action including further information gathering. Conclusion: Paediatric cancer parents need health literacy support to meet their information needs. They require guidance in identifying and appraising suitable information resources. Development of suitable supporting materials is needed to facilitate parents' ability to comprehend information related to their child's cancer. Understanding parents' information behaviour could assist healthcare professionals in providing information support in the context of paediatric cancer. [ABSTRACT FROM AUTHOR]

Statement of the Problem: Chemotherapy-induced mucositis is the most common complication during cancer treatment. This complication can lead to pain, increased risk of infection and malnutrition. Therefore, it is important to find a solution to reduce the severity and duration of side effects. Purpose: This study aimed to assess the efficacy of Mucosamin spray as an adjunct for prevention of oral mucositis in children under chemotherapy. Materials and Method: This parallel-design clinical trial evaluated 48 patients aged 5 to 15 years with leukemia and lymphoma presenting to the Hematology Department of Mofid and Mahak Hospitals. The patients were randomly divided into two groups (n=24). Before starting chemotherapy, all patients received oral hygiene instructions (toothbrushing without flossing). Patients in both groups were requested to use a mouthwash composed of nystatin, aluminum-magnesium hydroxide suspension (aluminum MgS), and diphenhydramine for 1 min every morning on a daily basis starting the day before treatment. Patients in the intervention group were also requested to spray their entire oral mucosa with Mucosamin spray 3 times a day in addition to using the mouthwash. Patients were requested to refrain from eating and drinking for 1h after spraying. The patients were clinically examined by a senior dental student once every other day for 20 days regarding the occurrence, severity, and duration of oral mucositis. Data were analyzed using the Chi-square and Mann-Whitney tests, Kaplan-Meier survival analysis, and log rank test. Results: No significant difference was noted between the two groups in the incidence, severity, or time of development of mucositis (p> 0.05). The 7-day non-recovery percentage was 72.7% (SE= 13.4) and 25.0% (SE= 15.3) in the control and test groups, respectively, indicating shorter duration (faster healing) of mucositis in the intervention group (p= 0.01). Conclusion: Within the limitations of this study, it seems that prophylactic application of Mucosamin spray can shorten the course of oral mucositis, in case of its occurrence.

Young children receiving outpatient cancer care are vulnerable to undermanaged pain. App‐based solutions that provide pain treatment advice to parents in real‐time and in all environments may improve access to quality pain care. We used a parent co‐design approach involving iterative rounds of user testing and software modification to develop a usable Pain Caregiver Resource (PainCaRe) real‐time pediatric cancer pain management app. Parents of children (2–11 years) with cancer completed three standardized modules using a PainCaRe prototype. App usability and acceptability were evaluated using the validated System Usability Scale and a thematic analysis of app testing sessions and interviews. Iterative testing sessions were conducted until data saturation. Interview themes were synthesized into action items that guided revisions to PainCaRe and additional testing rounds were conducted as necessary. Twenty‐two parents participated in three testing cycles. Overall, parents described PainCaRe as an acceptable and potentially clinically useful pain management tool. Mean system usability scores were in the acceptable scale range during each testing cycle. Usability issues identified and resolved included those related to software malfunction, complicated app navigation logic, lack of clarity on pain assessment questions, and the need for pain management advice specifically tailored to child developmental stage. Using co‐design methods, the PainCaRe cancer pain management app was successfully refined for its acceptability and utility to parents. Next steps will include a PainCaRe pilot study before evaluating the impact of the app on younger children's pain outcomes in a randomized controlled trial. [ABSTRACT FROM AUTHOR]

Pediatric gliomas are highly heterogeneous and have unique molecular characteristics. They are not smaller versions of adult gliomas. This review emphasizes the basic points of surgery, radiotherapy, and chemotherapy for pediatric gliomas, introduces the similarities and differences with targeted therapy for adult gliomas, describes the important driver gene abnormalities involved in pediatric gliomas and the corresponding targeted therapy strategies, and focuses on the epigenetic treatment strategies for pediatric diffuse high-grade gliomas caused by histone H3 mutations, and looks forward to the future work of diagnosis and treatment of pediatric gliomas.

Thromboembolism (TE) complicates the course of pediatric cancer in a considerable number of cases. Cancer-related TE is attributed to an interaction of the underlying malignancy, the effects of therapy, and a possible thrombophilia predisposition. More specifically, recognized risk factors include a very young age and adolescence, non-O blood group, type and site of cancer, inherited thrombophilia, presence of central venous catheter, and type of chemotherapy. TE in children with cancer most commonly occurs in their extremities. In the absence of evidence-based guidelines for the management of thrombotic complications in pediatric oncology patients, TE management follows general recommendations for the management of pediatric TEs. Given the limitations of conventional anticoagulant therapy, direct oral anticoagulants could provide an alternative; however, their safety and efficacy in children with cancer remain to be seen. As for thromboprophylaxis, numerous studies have been conducted, albeit with conflicting results. Although the survival of pediatric oncology patients has significantly improved in recent years, morbidity due to cancer-related TE remains, underlying the need for large multicenter trials investigating both TE management with currently available agents and primary prevention.

Background: With the widespread use of computed tomography (CT), the detection rate of pulmonary nodules in children has gradually increased. Due to the lack of epidemiological evidence and clinical guideline on pulmonary nodule treatment in children, we aimed to provide a reference for the clinical diagnosis and management of pediatirc pulmonary nodules. Methods: This retrospective study collected consecutive cases from April 2012 to July 2021 in the Shanghai Children's Medical Center. The sample included children with pulmonary nodules on chest CT scans and met the inclusion criteria. All patients were categorized into tumor and non-tumor groups by pre-CT clinical diagnosis. Nodule characteristics between groups were analyzed. To establish a clinical assessment model for the benign versus malignant pulmonary nodules, patients who have been followed-up for three months were detected and a decision tree model for nodule malignancy prediction was constructed and validated. Results: The sample comprised 1341 patients with an average age of 7.2 ± 4.6 years. More than half of them (51.7%) were diagnosed with malignancies before CT scan. 48.3% were diagnosed with non-tumor diseases or healthy. Compared to nontumor group, children with tumor weremore likely to havemultiple nodules in both lungs, with larger size and often be accompanied by osteolytic or mass lesions. Based on the decision tree model, patients' history of malignancies, nodules dia meter size=5mm, and specific nodule distribution (multiple in both lungs, multiple in the right lung or solitary in the upper or middle right lobe) were important potential predictors for malignity. In the validation set, sensitivity, specificity and AUC were 0.855, 0.833 and 0.828 (95%CI: 0.712-0.909), respectively. Conclusion: This study conducted a clinical assessment model to differentiate benignity and malignancy of pediatric pulmonary nodules. We suggested that a nodule's diameter, distribution and patient's history of malignancies are predictable factors in benign or malignant determination. [ABSTRACT FROM AUTHOR]

Simple Summary: Berlin–Frankfurt–Münster (BFM) protocols are widely used outside clinical trials to treat pediatric acute lymphoblastic leukemia patients. However, local specificities might demand treatment adaptations, like the reduction of high-dose methotrexate due to lack of pharmacokinetic monitoring, the substitution of conventional asparaginase for peg-asparaginase because of the unavailability of the latter, or flow-cytometry-based measurable residual disease instead of a PCR-based one. Here, we report the results of a 22-year period of children treated with BFM protocols in a developing country. The results were somewhat comparable to the BFM reports, and we conclude that BFM protocol adaptations can be safely implemented in developing countries, accounting for local specificities. Introduction: The objective of the current study was to determine the survival probabilities of children and adolescents with acute lymphocytic leukemia treated with adapted Berlin–Frankfurt–Münster (BFM) protocols and compare our results with the original BFM reports. Methods: This retrospective study included 695 patients up to 19 years old treated with adapted BFM protocols between 1997 and 2018 in four hospitals in Rio de Janeiro. The 1997–2007 and 2008–2018 cohorts were analyzed separately. Results: More than half of the patients were stratified into the high-risk BFM classification. Overall and event-free survivals were, in the 1997–2007 period, respectively, 88% and 80% (BFM standard risk group—SRG), 75% and 67% (intermediate risk group—IRG), and 48% and 33% (high-risk group—HRG). The corresponding numbers for the 2008–2018 period were 93% and 84% (SRG), 75% and 63% (IRG), and 64% and 57% (HRG). In the second period, both the OS (HR = 0.71, p = 0.011) and EFS (HR = 0.62, p < 0.001) were higher. Except for the intermediate-risk group, the latter results are comparable to the BFM. Conclusion: The BFM protocol adaptations can be safely implemented in developing countries, accounting for local specificities. [ABSTRACT FROM AUTHOR]

Background: Parameningeal rhabdomyosarcoma (PM-RMS) is a rare and aggressive soft tissue malignancy that primarily occurs in the head and neck region. The standard treatment approach for RMS involves a multimodal therapy regimen, which includes surgery, chemotherapy, and radiotherapy. However, the routine use of radiotherapy and chemotherapy in young patients with RMS in the head and neck region can lead to adverse effects on dental development and thereby, pose a challenge in planning dental intervention. Case presentation: This case report outlines the dental and facial developmental consequences in a 13-year-old child, who received chemo-radiotherapeutic intervention at the age of 7 years for the management of PM-RMS. Following treatment, the child exhibited significant dental complications, including arrested root growth and restricted mouth opening. Conclusions: This case highlights the necessity for interdisciplinary collaboration between oncologists, dentists, and other healthcare professionals to mitigate the adverse effects on dental health and overall quality of life in patients undergoing chemo-radiotherapy for rhabdomyosarcoma.

CONTEXT: There is an increasing population of childhood cancer survivors (CCS) at risk for treatment-related toxicities, including skeletal morbidities. Bone mineral density (BMD) is a proxy for bone health and reductions are associated with osteoporosis and fractures. OBJECTIVE: To investigate bone health in CCS by conducting a systematic review and meta-analysis of BMD after completed treatments. DATA SOURCES: We searched Medline, Embase, Cochrane, and Web of Science in May 2019 and updated in May 2023. STUDY SELECTION: Studies reporting BMD Z-scores measured with dual-energy x-ray absorptiometry in CCS after treatment completion. DATA EXTRACTION: We performed a pooled analysis of studies reporting BMD Z-scores and thereafter we analyzed studies comparing BMD in survivors and healthy controls. All analyses were performed based on the site of BMD measurement. RESULTS: Of 4243 studies, 84 were included (N = 8106). The mean time off-treatment across the studies ranged from 2 months to 24 years. The overall pooled mean Z-score was -0.57 (95% confidence interval [CI] -0.59 to -0.55) in the whole-body, -0.84 (95% CI -0.86 to -0.83) in the lumbar spine, -0.79 (95% CI -0.81 to -0.77) in the femoral neck and -0.14 (95% CI -0.18 to -0.11) in the total hip. When comparing survivors with controls, BMD was significantly lower in survivors at all sites. LIMITATIONS: English publications, study-level meta-analysis. CONCLUSIONS: We showed a significant reduction of BMD Z-scores in CCS. Given the increased fracture risk already within -1 SD, these results emphasize the need for BMD surveillance and secondary prevention in CCS. [ABSTRACT FROM AUTHOR]

BACKGROUND AND OBJECTIVES: Conversations about dignity are fundamental to person-centered care in pediatrics, yet practical language strategies to promote and support dignity remain understudied. To address this gap, we aimed to identify and characterize language used by pediatric oncologists to recognize and affirm dignity across advancing illness. METHODS: In this longitudinal prospective study, we audio-recorded serial disease reevaluation encounters between pediatric oncologists, children with cancer, and families across 24 months or until the child's death. Using a hybrid deductive--inductive qualitative approach, we defined dignity language a priori on the basis of existing descriptions of dignity in the literature and then conducted a content analysis to refine the definition specific to pediatric cancer care before coding serial medical encounters. Thematic frequencies were reported by using descriptive statistics. RESULTS: A total of 91 discussions at timepoints of disease progression were audio-recorded for 36 patients and their families. No dignity language was identified in nearly half (45%) of "bad news" encounters, and the time spent by the oncologist engaging in dignity language represented a minority (<7%) of overall recorded dialogue. Within coded dialogue, we characterized 3 key themes upholding dignity language (empowerment, autonomy, respect). CONCLUSIONS: Opportunities exist to improve dignity communication in childhood cancer, and the authors propose a conceptual model ("Lend an EAR") to guide dignity-based communication in pediatric cancer. Future research should emphasize patient and parent perspectives on language to support dignity for children with advanced cancer, with stakeholder-driven refinement of the Lend an EAR model before integration and testing in communication skills training programs.

Simple Summary: Pediatric, adolescent, and young adult (AYA) cancer patients, especially those with rare cancers, face unique challenges that traditional support systems may not adequately address. This study explores the potential of the metaverse, a virtual shared space, to provide psychological support and foster a sense of community among these patients. By utilizing customizable avatars and facilitating interactions across geographical and temporal barriers, the metaverse enables patients to connect with peers, share experiences, and receive emotional support. The anonymity provided by avatars helps reduce appearance-related anxiety and the stigma associated with cancer treatment. This research highlights the metaverse's potential to transform the delivery of psychosocial support for patients with rare cancers, offering a novel approach to patient care that transcends physical limitations and fosters a global patient community. The findings suggest that integrating virtual spaces into healthcare models can effectively meet the complex needs of pediatric and AYA cancer patients. This study investigated the potential of the metaverse in providing psychological support for pediatric and AYA cancer patients, with a focus on those with rare cancers. The research involved ten cancer patients and survivors from four distinct regions in Japan, who participated in metaverse sessions using customizable avatars, facilitating interactions across geographical and temporal barriers. Surveys and qualitative feedback were collected to assess the psychosocial impact of the intervention. The results demonstrated that the metaverse enabled patients to connect with peers, share experiences, and receive emotional support. The anonymity provided by avatars helped reduce appearance-related anxiety and stigma associated with cancer treatment. A case study of a 19-year-old male with spinal Ewing's sarcoma highlighted the profound emotional relief fostered by metaverse interactions. The findings suggest that integrating virtual spaces into healthcare models can effectively address the unique needs of pediatric and AYA cancer patients, offering a transformative approach to delivering psychosocial support and fostering a global patient community. This innovative intervention has the potential to revolutionize patient care in the digital age. [ABSTRACT FROM AUTHOR]

Background and Objective: Olanzapine (OLZ) containing regimens are approved in adults for chemotherapy-induced nausea and vomiting (CINV) receiving highly emetogenic chemotherapy (HEC) or moderately emetogenic chemotherapy (MEC), and the same has not been approved in the pediatric population. In order to generate data regarding the efficacy and safety of OLZ as an adjunct to the standard of care (SoC) for CINV in pediatric patients receiving HEC/MEC, the review authors performed this systematic review and meta-analysis. Methods: A systematic literature search was performed through the databases Cochrane Library, Pub Med, and clinicaltrials.gov, from inception to September 2023, using keywords: "chemotherapy" and "olanzapine," "nausea" and "vomiting." Randomized clinical trials published in English that analyzed the efficacy and safety of olanzapine as an adjunct to SoC were included. The essential outcomes included in this study were the proportion of patients with no emesis in the acute and delayed phase, patients with no nausea in the acute and delayed phase, the proportion of patients requiring rescue medication, and the proportion of patients with reduced CNS arousal. Results: In the OLZ group, a greater number of patients had no emesis both in the acute and delayed phase (RR = 1.22; 95% CI = 1.09-1.37; P =.0004); and (RR = 1.23; 95% CI = 0.92-1.63; P =.16) respectively. Similarly, a higher number of patients showed no nausea both in the acute and delayed phase (RR = 1.08; 95% CI = 0.78-1.48; P =.66) and (RR = 1.12; 95% CI = 0.79-1.61; P =.52) respectively. The use of rescue medication was significantly less in the OLZ group (RR = 0.62; 95% CI = 0.42-0.91; P =.01). More patients experienced reduced CNS arousal in the OLZ group (RR = 2.97; 95% CI = 2.02-4.38; P <.0001). Conclusions: Olanzapine as an adjunct to the SoC may be effective in acute emesis, which may also reduce the use of rescue medication. Reduced CNS alertness was the significant adverse effect observed. For other endpoints, more studies are required to substantiate its role in CINV. [ABSTRACT FROM AUTHOR]

Purpose: Pediatric spinal cord gliomas (PSGs) are rare in children and few reports detail their imaging features. We tested the association of tumoral grade with imaging features and proposed a novel approach to categorize post-contrast enhancement patterns in PSGs. Methods: This single-center, retrospective study included patients <21 years of age with preoperative spinal MRI and confirmed pathological diagnosis of PSG from 2000-2022. Tumors were classified using the 5th edition of the WHO CNS Tumors Classification. Two radiologists reviewed multiple imaging features, and classified enhancement patterns using a novel approach. Fisher's exact test determined associations between imaging and histological features. Results: Forty-one PSGs were reviewed. Thirty-four were intramedullary, and seven were extramedullary. Pilocytic astrocytoma was the most common tumor (39.02%). Pain and weakness were the most prevalent symptoms. Seven patients (17.07%) died. Cyst, syringomyelia, and leptomeningeal enhancement were associated with tumor grade. Widening of the spinal canal was observed only in low-grade astrocytomas. There was a significant association between tumor grade and contrast enhancement pattern. Specifically, low-grade PSGs were more likely to exhibit type 1A enhancement (mass-like, with well-defined enhancing margins) and less likely to exhibit type 1B enhancement (mass-like, with ill-defined enhancing margins). Conclusion: PSGs display overlapping imaging features, making grade differentiation challenging based solely on imaging. The correlation between tumor grade and contrast enhancement patterns suggests a potential diagnostic avenue, requiring further validation with larger, multicenter studies. Furthermore, Low-grade PSGs display cysts and syringomyelia more frequently, and leptomeningeal enhancement is less common. [ABSTRACT FROM AUTHOR]

Background: One of the main drawbacks of tunneled central venous catheters (CVCs) is catheter-related bloodstream infections (CRBSIs). Antibiotic lock therapy (ALT) can be combined with systemic antibiotics to achieve catheter salvage. Our objectives are to describe cases of CRBSI and our experience with ALT in a pediatric oncology–hematology ward. Methods: a retrospective descriptive study of pediatric CRBSI cases in a Spanish oncology–hematology unit from 2007 to 2017 was conducted. We collected demographic, clinical, and microbiological data from all patients. Results: fifty-eight CRBSIs were diagnosed in thirty-nine patients; 72.9% of these patients were male, with a median age of 42.1 months. The main underlying diseases were leukemia/lymphoma (51.7%) and solid tumors (32.7%). Thirty-five (60.3%) CRBSIs were caused by Gram-positive cocci, of which 70.6% were coagulase-negative Staphylococci, and sixteen (27.6%) were caused by Gram-negative bacilli. We treated 41/58 (71%) cases with ALT. A total of 12/17 (71%) CVCs that were not treated with adjunctive ALT were removed, compared with 13/41 (32%) that were treated with ALT (relative risk (RR), 0.449; confidence interval (CI), 95%: 0.259–0.778, p = 0.004). Major reasons to remove the CVC in the CRBSI-ALT group were local insertion/pocket site infection (23%), persistent symptoms (23%), and infectious' relapses (15%). Conclusions: ALT was shown to be an effective approach to keeping the CVC in place, with no added adverse effects. [ABSTRACT FROM AUTHOR]

Wilms tumor (WT) is the most common kidney tumor in pediatric patients. Intravascular extension of WT above the level of the renal veins is a rare manifestation that complicates surgical management. Patients with intravascular extension are frequently asymptomatic at diagnosis, and tumor thrombus extension is usually diagnosed by imaging. Neoadjuvant chemotherapy is indicated for thrombus extension above the level of the hepatic veins and often leads to thrombus regression, obviating the need for cardiopulmonary bypass in cases of cardiac thrombus at diagnosis. In cases of tumor extension to the retrohepatic cava, neoadjuvant therapy is not strictly indicated, but it may facilitate the regression of tumor thrombi, making resection safer. Hepatic vascular isolation and cardiopulmonary bypass increase the risk of bleeding and other complications when utilized for tumor thrombectomy. Fortunately, WT patients with vena caval with or with intracardiac extension have similar overall and event-free survival when compared to patients with WT without intravascular extension when thrombectomy is successfully performed. Still, patients with metastatic disease at presentation or unfavorable histology suffer relatively poor outcomes. Dedicated pediatric surgical oncology and pediatric cardiothoracic surgery teams, in conjunction with multimodal therapy directed by a multidisciplinary team, are preferred for optimized outcomes in this patient population.

Background: The death of a child is one of the most devastating events a family can face, resulting in significant physical and psychosocial morbidity. Bereavement support programs have been developed in high-income contexts to address this need. However, little is known about implementing bereavement programs in low-and middle-income countries (LMICs). Here, we describe the implementation of a bereavement program for parents whose children died due to cancer or other catastrophic illnesses. Methods: We conducted a retrospective analysis to describe the implementation of a hospital-based End of Life (EoL) care and bereavement program. This program was developed in several stages, including an assessment of bereaved families, development program guidelines, staff training, piloting of the program, refinement, and standardization. The program was developed between 2019 and 2021 in a nonprofit, teaching hospital and referral center for southwestern Colombia. Results: Several tools were developed as key components of the bereavement program: a virtual bereavement course; guidance for EoL and bereavement communication and care, memory making, and follow-up calls; a condolence letter template, and group support workshops. A total of 956 healthcare professionals were trained, 258 follow-up calls to bereaved parents were made, 150 individual psychological follow-ups to parents with complicated grief occurred, 79 condolence letters were sent, and 10 support group workshops were carried out. Challenges were identified and overcome, such as limited resources and staff, and cultural perceptions of death. In 2021, this program received an award by the hospital as the Best Strategy to Humanize Healthcare. Conclusions: This study highlights the feasibility of developing and implementing EoL and bereavement care programs for parents and families within hospitals in LMICs. Lack of resources, staff, and training are some of the identified challenges to implementation. Utilizing methodological tools allows us to identify facilitator factors and deliverable outcomes of our EoL and bereavement program. This model provides a valuable framework for resource-limited settings. [ABSTRACT FROM AUTHOR]

Introduction: It has been reported that non-intubated anesthesia can be used successfully in adult trachea reconstruction. Herein, our center reported a case of a child undergoing non-intubated trachea reconstruction for benign tracheal tumors. Case description: In January 2023, it was decided to attempt tracheal resection and reconstruction (TRR) in an 8-year-old child with an inflammatory myofibroblastic tumor under non-intubated spontaneous breathing. After anesthesia induction, the laryngeal mask airway (LMA) was inserted. Thereafter, a bilateral superficial cervical plexus block was performed with 15 mL of 0.25% ropivacaine injected into each side. The patient was induced to resume spontaneous breathing by artificially assisted ventilation with an oxygen flow of 2 to 5 L/min and FiO2=1. After tracheotomy, the oxygen flow was increased to 15 L/min to improve the local oxygen flow to maintain the pulse oxygen saturation (SpO2) above 90% under spontaneous breathing. The patient had stable spontaneous breathing after tracheal anastomosis. The anastomosis was perfect without leakage. The LMA was removed and oxygen was given by the nasal catheter under light sedation at post anesthesia care unit (PACU). Conclusion: Tracheal reconstruction under spontaneous breathing may be an alternative anesthesia method for upper tracheal surgery in children. [ABSTRACT FROM AUTHOR]

Introduction: Lipoblastoma is a benign tumor derived from embryonic adipose tissue, accounting for 5 to 30 percent of soft tissue tumors in children. This study presents a case of a rapidly growing thigh mass in a 16-month-old child, for whom diagnosis based solely on serial clinical examinations proved challenging. Case Presentation: A 16-month-old girl presented with a lump at the posterior aspect of her left knee. Due to the rare nature of the tumor, diagnosis was delayed. Although serial clinical examinations showed no change in size, subsequent imaging revealed rapid growth, leading to a definitive diagnosis. Conclusion: In cases of fast-growing masses in children, particularly those with prominent adipose tissue imaging findings, it is crucial to consider lipoblastoma in the differential diagnosis. Advanced imaging methods should be recommended for monitoring, as serial examinations lack sufficient sensitivity in lipoblastoma follow-up. Our study underscores the limitations of serial examinations in lipoblastoma cases. Accurate diagnosis requires a combination of imaging studies and clinical evaluation. Once a definitive diagnosis is confirmed, prompt surgical removal of the tumor is advisable. [ABSTRACT FROM AUTHOR]

Introduction: Central Line-associated Bloodstream Infections (CLABSI's) burden the health care of children with cancer. Aim: The purpose of the study was to investigate CLABSI's in children with cancer. Material-Method: Systematic review of the literature carried out from 2012-2022, with a search for articles using keywords in international bibliographic databases (PubMed, Scopus). The study sample includes published research articles addressing the treatment, incidence, and risk factors for CVC infections. The inclusion criteria for the articles in the study were: 1. to be written in the English language, 2. to concern children (<18 years old) with cancer who carry central venous line (CVL), 3. to concern the CLABSI's of these children. After searching the databases a total of 12 articles were retrieved. Results: CLABSI's in children with cancer concern 4.5-29% of those children with CVL's. The most common organisms seen in CLABSI's were coagulase-negative staphylococci and Klebsiella pneumoniae and fungi. The factors related to the occurrence of CLABSI's in children with cancer mainly concern the degree of acute illness, the degree of neutropenia, the type of catheter, the intensive administration of chemotherapy, parenteral nutrition, the length of hospital stay, the place of admission of the catheter, antibiotic use, CVL insertion day and function, number of blood transfusions and number of blood tests. Compliance of health professionals with recommended measures for CVL care remains high while compliance of parents/families is low. Conclusions: Healthcare professionals caring for children with cancer should systematically monitor for the occurrence of CLABSI's, take measures to limit the factors that influence their occurrence, and inform/educate parents to comply with the guidelines for care of CVL's.

Physical activity and diet have complementary benefits for attenuating adverse health effects that childhood cancer survivors experience after the end of treatment. This review aimed to explore the impact of combined physical activity and diet interventions on the health status of childhood cancer survivors. A thorough review of the literature was carried out using the Cochrane Library, PubMed, Scielo, LILACS and Web of Science databases for studies published until June 2024. Studies concerning survivors of childhood cancer of any type engaged exclusively in combined diet/physical activity interventions were included in this review. Three manuscripts met the inclusion criteria. The results indicated that combined physical activity plus diet interventions showed beneficial impacts for the intestinal microbiome, percentage of calories from sweet foods, daily consumption of sugary beverages, reduction in sedentary activity, and mood (1 out of 1 study for each of the presented outcomes). Although more rigorous studies are needed, these findings showed promising results regarding the impact of interventions involving both physical activity and diet on childhood cancer survivors [ABSTRACT FROM AUTHOR]

Introduction: Rapidly increasing costs of medication acquisition can pose a challenge for health-system pharmacy budgets. The impact of dose-rounding in a pediatric oncology population has not previously been well documented and a retrospective review was undertaken to quantify the potential cost benefits. Methods: A retrospective chart review of patients with an oncologic diagnosis was performed for cytotoxic agents, asparaginase products, and biotherapy administered between January 1, 2014, and December 31, 2017. In the analysis, orders that could be rounded down to the nearest vial size by 5 or 10% were included. Medication pricing information was based on wholesale acquisition cost (WAC) and was provided by the Department of Pharmacy. Cost savings per medication were determined by multiplying the WAC of the medication by the number of vials saved. Results: Over a 4-year span, 347 patients were evaluated and 552 out of a possible 3110 orders (17.7%) met criteria for a theoretical cost savings of approximately $1,126,000 (∼$3200 per patient). Rounding down doses by up to 5% resulted in a potential savings of about $529,000. When rounding was extended to 5–10% of the originally ordered dose, an additional $597,000 of approximate cost savings could have been realized. The medications with the largest impact on cost savings were rituximab, pegaspargase, and erwinia asparaginase. Conclusions: For pediatric oncology patients, there exists a unique potential cost savings opportunity if doses are rounded down within 5 or 10% of the originally ordered weight-based or body surface area-calculated dose.

To investigate the incidence rate of primary brain tumors (PBTs) among Palestinian children over a 6-year interval. This study also aimed to identify the predominant histopathologic types identified in these children. This retrospective epidemiologic study focused on PBTs in children (<15 years) in Palestine. The data were collected from the registry system at Al-Makassed Hospital in Jerusalem, a prominent referral institution in Palestine and the largest center for PBTs in the region, over a 6 years period from 2018 to 2023. The incidence rate of PBTs in children (<15 years) was 1.33 per 100,000 person-years, with a 5% mortality rate. Pilocytic astrocytoma was the most common type (24%), followed by medulloblastoma (15.2%) and glioblastoma (6.3%). About one half of the tumors in children were malignant. Headaches were the most common first sign or symptom. About 20% of brain tumors in children were situated within the ventricles, making it the most prevalent location of these tumors, followed by the cerebellum (15.19%) and frontal lobe (11.39%). This is the first national study in Palestine investigating PBTs in children. The crude incidence rate of primary brain tumors among Palestinian children was lower than the incidence rate in many countries around the world. It is recommended that more research be done on the epidemiology and distribution of PBTs in children in Palestine. [ABSTRACT FROM AUTHOR]

Aim: Malignant chest wall tumors are rare in children. We aimed to study the management of the Ewing family of tumors (EFT) in the chest walls of children. Materials and Methods: The files of patients diagnosed with primitive neuro-ectodermal tumor and Ewing sarcoma of the chest wall in the prior 2 decades were retrospectively reviewed. Results: A total of 15 children with a median age of 10 (8-14) years were included. Their symptoms were palpable mass (n=6), chest pain (n=4), B symptoms (n=2), cough (n=2) and abdominal pain. Their history revealed delayed diagnoses in 1/3 of the patients due to a misinterpretation of the symptoms. All children except for one had tru-cut biopsy and upfront chemotherapy. The median greatest diameter of mass at diagnosis was 100 (67-148) mm and 51 (39-100) mm at preoperative imaging after chemotherapy. Pleural effusion (n=8), costal destruction (n=9), extension to neural foramina (n=3), pulmonary or diaphragmatic nodule (n=5) and distant bone metastasis (n=4) were present at diagnosis in some cases. More than one surgery was performed in 9 (60%) of the children in order to remove the primary tumor and metastases. Costal excision (n=11), diaphragmatic resection (n=6) and chest wall reconstruction with graft material were performed on 8 patients. All cases had radiotherapy postoperatively. Mortality occurred in 9 (60%) patients due to local recurrences or metastases. Only 3 children reached 5-year survival and were considered to be cured. The remaining 3 patients completed their first line oncologic treatments and were under surveillance without treatment. Conclusion: The EFT in the chest wall are aggressive tumors with poor prognosis despite multimodality treatment. Surgeons dealing with these patients should be familiar with complex chest wall reconstruction techniques. [ABSTRACT FROM AUTHOR]

Premature ovarian insufficiency (POI) is one of many potential long-term consequences of childhood cancer treatment in females. Causes of POI in this patient population can include chemotherapy, especially alkylating agents, and radiation therapy. Rarely, ovarian tumors lead to ovarian dysfunction. POI can manifest as delayed pubertal development, irregular menses or amenorrhea, and infertility. This diagnosis often negatively impacts emotional health due to the implications of impaired ovarian function after already enduring treatment for a primary malignancy. The emerging adult may be challenged by the impact on energy level, quality of life, and fertility potential. POI can also lead to low bone density and compromised skeletal strength. This review discusses the health consequences of POI in childhood cancer survivors (CCS). We also explore the role of fertility preservation for CCS, including ovarian tissue cryopreservation and other available options. Lastly, knowledge gaps are identified that will drive a future research agenda. [ABSTRACT FROM AUTHOR]

The experience of childhood cancer (CC) could be a traumatic event that produces long-term emotional responses such as posttraumatic stress symptoms (PTSS) and posttraumatic growth (PTG) in survivors. The relationship between both PTSS and PTG is not clear in CC survivors. Assessing challenges to core beliefs and rumination could give information regarding the different paths that lead to traumatic responses. Thus, this study aims to identify childhood cancer survivors' profiles from PTSS and PTG measures and to examine the pathways of relationships between PTSS and PTG, rumination, and challenge to core belief. Sixty-two CC survivors completed surveys on their childhood cancer experience, PTSS, PTG, challenge to core beliefs, and rumination. High PTG scores among childhood cancer survivors (Cluster 1), High PTSS scores among childhood cancer survivors (Cluster 2), and Childhood cancer survivors without changes (Cluster 3). Network analysis found that the challenge to core beliefs is the central point in the relationship between the variables, in a direct and positive relationship with PTG. We found an indirect path from challenge to core beliefs to PTSS, mediated by intrusive and deliberative ruminations. The combined findings suggested that there are different profiles related to trauma in CC survivors and the relationship between PTSS and PTG is mediated by the challenge to core beliefs and deliberative and intrusive rumination.

Objective: We examined the impact of long-term mental health outcomes on healthcare services utilisation among childhood cancer survivors in Western Australia using linked hospitalisations and community-based mental healthcare records from 1987 to 2019. Method: The study cohort included 2977 childhood cancer survivors diagnosed with cancer at age < 18 years in Western Australia from 1982 to 2014 and a matched non-cancer control group of 24,994 individuals. Adjusted hazard ratios of recurrent events were estimated using the Andersen–Gill model. The cumulative burden of events over time was assessed using the method of mean cumulative count. The annual percentage change in events was estimated using the negative binomial regression model. Results: The results showed higher community-based service contacts (rate/100 person-years: 30.2, 95% confidence interval = [29.7–30.7] vs 22.8, 95% confidence interval = [22.6–22.9]) and hospitalisations (rate/1000 person-years: 14.8, 95% confidence interval = [13.6–16.0] vs 12.7, 95% confidence interval = [12.3–13.1]) in childhood cancer survivors compared to the control group. Childhood cancer survivors had a significantly higher risk of any event (adjusted hazard ratio = 1.5, 95% confidence interval = [1.1–2.0]). The cumulative burden of events increased with time since diagnosis and across age groups. The annual percentage change for hospitalisations and service contacts significantly increased over time (p < 0.05). Substance abuse was the leading cause of hospitalisations, while mood/affective and anxiety disorders were common causes of service contacts. Risk factors associated with increased service events included cancer diagnosis at age < 5 years, leukaemia diagnosis, high socioeconomic deprivation, and an attained age of < 18 years. Conclusions: The elevated utilisation of healthcare services observed among childhood cancer survivors emphasises the need for periodic assessment of psychiatric disorders, particularly in high-risk survivors, to facilitate early management and optimise healthcare resources.

Simple Summary: Our findings confirm the role of developmental aspects in extracranial germ cell tumors (eGCTs). Strong associations between syndromes or congenital anomalies and eGCTs may hint at the need for research to identify potential causes and mechanisms. Strong effects were observed for Swyer and Currarino syndrome. The strengths of the associations emphasize the need for further elaboration on presently discussed pathophysiological mechanisms. For other suggested risk factors such as Klinefelter, Turner, and Down syndrome, the strength of risk appears to be substantially low and may be missed because of diagnostic bias for the first two or lack of power for the latter. A number of further syndromes were identified in single cases. Most of these pertain to girls. GCTs are developmental tumors and are likely to reflect ontogenetic and teratogenetic determinants. The objective of this study was to identify syndromes with or without congenital anomalies and non-syndromic defects as potential risk factors. Patients with extracranial GCTs (eGCTs) registered in MAKEI 96/MAHO 98 between 1996 and 2017 were included. According to Teilum's holistic concept, malignant and benign teratomas were registered. We used a case–control study design with Orphanet as a reference group for syndromic defects and the Mainz birth registry (EUROCAT) for congenital anomalies at birth. Co-occurring genetic syndromes and/or congenital anomalies were assessed accordingly. Odds ratios and 95% confidence intervals were calculated and p-values for Fisher's exact test with Bonferroni correction if needed. A strong association was confirmed for Swyer (OR 338.6, 95% CI 43.7–2623.6) and Currarino syndrome (OR 34.2, 95% CI 13.2–88.6). We additionally found 16 isolated cases of eGCT with a wide range of syndromes. However, these were not found to be significantly associated following Bonferroni correction. Most of these cases pertained to girls. Regarding non-syndromic defects, no association with eGCTs could be identified. In our study, we confirmed a strong association for Swyer and Currarino syndromes with additional congenital anomalies. [ABSTRACT FROM AUTHOR]

Simple Summary: Reports of a significant increase in young-onset cancers in South Australia (SA) with a higher-than-average incidence in the Northern Territory (NT) in the last 3 decades. Cancer incidence significantly decreased over time amongst non-Indigenous children but remained unchanged amongst Indigenous children (NT). Overall survival improved in SA, but unchanged in the NT. In the NT, overall survival of Indigenous children was significantly lower than non-Indigenous children, but survival rates in the former have improved. Ongoing targeted public health response is needed to reduce disparities in cancer health care outcomes for Indigenous Australians as outlined within the Australian and the Aboriginal and Torres Strait Islander Cancer Plans. Background & Aims: Reports of a rise in childhood cancer incidence in Australia and globally prompted the investigation of cancer incidence and survival in South Australia (SA) and the Northern Territory (NT) over a 28-year period, with emphasis on Indigenous peoples. Methods: This cross-sectional analysis of two prospective longitudinal databases, the SA and NT Cancer Registries (1990–2017), included all reported cases of childhood cancers. Poisson regression provided estimates of incidence rate ratios and survival was modelled using Cox proportional hazard models for children aged <5 and ≥5 years. Results: A total of 895 patients across SA (N = 753) and the NT (N = 142) were ascertained. Overall and in the NT, childhood cancer incidence was higher in males compared with females (IRR 1.19 [1.04–1.35] and 1.43 [1.02–2.01], respectively). Lymphocytic leukemia was the most reported cancer type across all locations. With reference to the 1990–1999 era (181.67/100,000), cancer incidence remained unchanged across subsequent eras in the combined cohort (SA and NT) (2000–2009: 190.55/100,000; 1.06 [0.91–1.25]; 2010–2017: 210.00/100,000; 1.15 [0.98–1.35]); similar outcomes were reflected in SA and NT cohorts. Cancer incidence amongst non-Indigenous children significantly decreased from the 1990–1999 era (278.32/100,000) to the 2000–2009 era (162.92/100,000; 0.58 [0.35–0.97]). Amongst 39 Indigenous children in the NT, incidence rates remained unchanged across eras (p > 0.05). With reference to the 1990–1999 era, overall survival improved in subsequent eras in SA (2000–2009: HR 0.53 [0.38–0.73]; 2010–2017: 0.44 [0.28–0.68]); however, remained unchanged in the NT (2000–2009: 0.78 [0.40–1.51]; 2010–2017: 0.50 [0.24–1.05]). In the NT, overall survival of Indigenous patients was significantly lower compared with the non-Indigenous cohort (3.42 [1.92–6.10]). While the survival of Indigenous children with cancer significantly improved in the last two eras (p < 0.05), compared to the 1990–1999 era, no change was noted amongst non-Indigenous children in the NT (p > 0.05). Conclusions: The incidence of childhood cancers has remained unchanged over 28-years in SA and the NT. Encouragingly, improved survival rates over time were observed in SA and amongst Indigenous children of the NT. Nevertheless, survival rates in Indigenous children remain lower than non-Indigenous children. [ABSTRACT FROM AUTHOR]

For pediatric patients with cancer, a healthy lifestyle is important for treatment outcomes and beyond. General pediatricians play a major role in the care of these patients, particularly given the improved rates of survival. Pediatric obesity has many negative consequences, but it is an area where primary care providers can make an impact and provide support to childhood cancer survivors. To provide the best quality of care for this population, there must be collaboration between primary care and oncology providers. Additionally, general practioners should feel empowered to offer standard nutrition and physical activity recommendations to all childhood cancer survivors. For pediatric patients who carry a cancer diagnosis, cure is no longer the only goal. Pediatric providers across specialties need to work as a team to improve long-term quality of life for these patients, starting with modifiable healthy habits. [ABSTRACT FROM AUTHOR]

Objectives: The objective of this study is to summarize the clinical characteristics, treatment, and prognosis of parotid tumors in children and adolescents. Methods: Fifty-three children and adolescents diagnosed with parotid gland tumors were included. Survival was evaluated using the Kaplan-Meier method. Log-rank test and multivariate analysis were used to analyze the association between clinical factors and recurrence. Results: Of the 53 patients, 30 cases were benign and 23 cases were malignant. All patients underwent surgery. Patients with malignant tumors with high-risk factors received radiotherapy or chemotherapy. The median follow-up time was 61 months. Of these, 1 patient with benign tumor and 5 patients with malignant tumors recurred. Of the patients with malignant tumors, 2 developed distant metastases and 2 died. The 5-year overall survival (OS) and 5-year locoregional recurrence-free survival (LRFS) rates for benign tumors were 100.0% and 92.9%, respectively, whereas the 5-year OS and 5-year LRFS rates for malignant tumors were 94.4% and 72.5%, respectively. The log-rank univariate test showed that tumor size >3.5 cm (p = .056), distant metastasis (p = .056), and stage III and IV (p = .032) were associated with recurrence. However, multivariate analysis did not show the above factors to be independent prognostic factors for LRFS. Conclusion: Surgery for benign tumors depends on the location and size. Surgery for malignant parotid tumors depends mainly on the stage, grade, pathological type, and recurrence. Prophylactic lymph node dissection is required for high-grade tumors. Radiotherapy or chemotherapy for children needs more research. Both benign and malignant tumors have high survival rates after active treatment. [ABSTRACT FROM AUTHOR]
