To review biliary complications following liver resection for liver tumors in children and their associated risk factors.
Retrospectively, we reviewed children who underwent liver resection for liver ...tumors from 2010 to 2019. Demographic data, operative details, types of complications, interventions and outcomes were studied.
Eighty-six out of 108 liver resections were included in this study. The median age of patients was 1.8 years old, and 55% were male. The majority (95%) were malignant tumors, of which 87% were hepatoblastoma (n=71). The most common procedure performed was extended right hepatectomy (37%, n=32). Twelve (14%) patients had primary biliary complications: nine bile leakages and three biliary obstructions. Six cases of bile leakage were treated non-operatively with drainage only; however, one developed bilothorax. Three bile leakages underwent early operative intervention. Four patients underwent biliary reconstruction. Biliary complications were not significantly associated with age, sex, ethnicity or pathology of the tumor. Ten of them (83%) developed following extended hepatectomies (five right, five left), in which the left side had a higher rate of complications (63% vs 16%). None of the central hepatectomies had biliary complications. Biliary complication rates were significantly higher among those who had segmentectomy 1 (p=0.023).
Biliary complication is a significant morbidity following liver resection in children. Surgery is eventually required for complicated bile leakage and primary biliary strictures. Follow-up is mandatory since secondary biliary complications may occur after the initial resolution of bile leakage. The groups at high risk of developing biliary complications are extended left hepatectomies and segmentectomy 1.
Methotrexate (MTX) is the mainstay of the consolidation and maintenance phase of chemotherapy protocol for childhood acute lymphoblastic leukemia (ALL). This study aimed to investigate the altered ...metabolism associated with high dose-MTX and determine the potential of the metabolic markers and differential pathways involved in MTX therapy.
Serum samples were collected from 38 children with ALL at 2 time points: p-MTX; before induction chemotherapy was initiated, and post-MTX; after completion of the first high-dose MTX. The samples were analyzed using HPLC/MS-QTOF. Data acquisition was performed using Agilent MassHunterTMB.05.00 software for subsequent metabolomics analysis. Differential expressions of metabolites were analyzed using univariate Welch's t-test unequal variance. Compounds were identified using the METLIN Database. Pathways and network analyses were performed using Metaboanalyst 4.0. Potential biomarkers were analyzed using the Receiving Operator Characteristic curve.
Metabolites with AUC between 0.7 and 0.9 include xanthine (0.889), oxoglutaric acid (0.770), and alpha-linolenic acid (ALA) (0.741). Alpha-linolenic acid abundance was detected in ALL patients with remission status, corresponding to a test sensitivity and specificity of 0.77 and 0.87, respectively. ALA has an antineoplastic effect that potentially inhibits the proliferation of leukemic cells by inhibiting caspase activation in the phosphatidylinositol 3-kinase (PI3K) pathway and Bcl-2 inhibition.
In this study, ALA was found to be significantly higher in patients treated with high-dose MTX and associated with remission status than in pre-MTX treatment.
ObjectiveThalassaemia is the most common inherited blood disorder in Malaysia. This study aims to report the current status of thalassaemia in Malaysia and provide a comprehensive understanding of ...the disease through data obtained from the Malaysian Thalassaemia Registry.DesignData were extracted from the Malaysian Thalassaemia Registry, a web-based system accessible to enrolled users through www.mytalasemia.net.my.SettingThe Malaysian Thalassaemia Registry data was recorded from reports obtained from 110 participating government and university hospitals in Malaysia.ParticipantsThe patients were those attending the 110 participating hospitals for thalassaemia treatment.InterventionData were collected from the Malaysian Thalassaemia Registry from 2007 until the fourth quarter of 2018.Primary outcome measure7984 out of 8681 patients with thalassaemia registered in the Malaysian Thalassaemia Registry were reported alive.ResultsMajority of the patients were reported in the state of Sabah (22.72%); the largest age group affected was 5.0–24.9 years old (64.45%); the largest ethnic group involved was Malay (63.95%); and the major diagnosis was haemoglobin E/β-thalassaemia (34.37%). From the 7984 patients, 56.73% were on regular blood transfusions and 61.72% were on chelation therapy. A small fraction (14.23%) has undergone splenectomy, while the percentage of patients with severe iron overload (serum ferritin ≥5000 µg/L) reduced over time. However, cardiac complications are still the main cause of death in patients with thalassaemia.ConclusionData gathered into the registry can be used to understand the progression of the disorder, to monitor iron overload management and to improve the outcomes of treatment, to enhance preventive strategies, reduce healthcare burden and improve the quality of life. Sustainability of the Malaysian Thalassaemia Registry is important for surveillance of thalassaemia management in the country and help the national health authorities to develop more effective policies.
The emergence of COVID-19 pandemic has led to heightened fear and uncertainty among parents of children with cancer. This study was conducted to evaluate the parental perceptions toward effects of ...COVID-19 infection to children with cancer, determine their stress level and factors contributing to high stress level during the pandemic.
This cross-sectional study was conducted in three paediatric oncology centres in Malaysia from September 2020 until December 2022. A total of 167 parents were recruited. Parents completed a set of questionnaires to assess their perception on effect of COVID-19 infection to children with cancer and COVID Stress Scale (CSS) to assess the parents' stress level.
Patients' mean age at study entry was 8.75 years (SD 4.38). Ninety-one (54.5%) patients were still on active treatment. More than 80% of the parents obtained information regarding COVID-19 infection from mass media and social networking. Fear of their children contracting COVID-19 infection was high especially among patients who were still on treatment. Forty-nine (29.3%) parents were significantly affected by the pandemic leading to loss of job or monthly income. Twenty-nine (17.4%) patients required treatment modification during the pandemic. The median total score for CSS was 78.0 (IQR 25
64.0; 75
95.0). Ninety-one (54.5%) respondents were very/extremely stressed based on the CSS scores. Components with high scores were xenophobia (median score 18.0; IQR 25
13.0, 75
22.0), fear of danger (median score 17.0; IQR 25
14.0, 75
20.0) and contamination fears (median score 16.0; IQR 25
12.0, 75
19.0). Lower household income was associated with higher stress level (
= 0.006).
Our study demonstrated high awareness regarding risk of COVID-19 infection among parents of oncology children. Half of the parents had high stress level, with low household income identified as a factor associated with high stress level.

regimen. The objective of this ...study was to investigate the genetic variations associated with the serum level and toxicity of MTX in Malaysian children with acute lymphoblastic leukemia (ALL). Thirty-eight patients were genotyped for rs717620 (ABCC2), rs4948496 (ARID5B), rs1801133 (MTHFR) and rs4149056 (SLCO1B1). Serum levels of MTX at 48 h post 24 h of intravenous infusion were analyzed by high-performance liquid chromatography-mass spectrometry. The ABCC2 genotype was significantly associated with the serum levels of MTX at 48 h after treatment (p = 0.017). Patients with CT and TT of rs717620 (ABCC2) and TC and CC of rs4948496 (ARID5B) were significantly associated with leukopenia grade I-IV (Fisher Exact Test; p = 0.03 and 0.02, respectively). The three most common MTX related toxicities were leukopenia (60.5%), increased alanine aminotransferase enzyme (47.4%), and thrombocytopenia (47.4%). Our results demonstrate that by prescreening of patients for ABCC2 and ARID5B associated with the serum levels and adverse effects of MTX would identify patients at risk and therefore help a pediatric oncologist to personalize chemotherapy drugs for precision health.
Abstract BACKGROUND Virtual pediatric neuro-oncology tumor board meetings have been reported to be highly beneficial in improving the delivery of high-quality care for childhood central nervous ...system (CNS) tumors. However, such meetings are lacking in the Asia Pacific region. Hence, we initiated the first pediatric neuro-oncology online platform in the Asia Pacific region in January 2019, and we aimed to describe the participants’ perception of the virtual tumor board meetings. METHODS We retrospectively reviewed all cases from January 2019 to December 2023 and conducted a web-based survey to all participants in December 2023. Centers that presented more than five cases were invited to assess the impact of virtual meetings. RESULTS Fifty-four meetings have been conducted over five years. A total of 160 cases were presented by 20 institutions from six Asian countries, which include Malaysia, Singapore, Philippines, Vietnam, India, and Taiwan. Thirty participants responded to the survey. Majority of them attended the meetings to enhance their knowledge in pediatric neuro-oncology (96.7%), to learn evidence-based management (83.3%), and to build connections with regional colleagues and international experts (53.3%). Almost all concluded that tumor board meetings improved treatment decisions, addressed challenges of complex CNS tumor cases, and promoted continuity of care with appropriate post-surgical chemotherapy administration and surveillance investigations after completion of treatment. The main reason for case discussion was diagnostic difficulties followed by multimodal treatment advice (85.7%). More than 25% of management changes were observed in pathological diagnosis and treatment approaches. All the hospitals reported that the online case discussions improved pediatric neuro-oncology service delivery capacity and increased local team competence. CONCLUSION Virtual pediatric neuro-oncology tumor board meetings facilitated improvement in pathological diagnosis and multimodal treatment approach. The establishment of virtual CNS tumor board meetings is an effective way to seek international expert advice and promote pediatric neuro-oncology education in our region.
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.
This ...article aims to explain paediatric cancer parents' information behaviour related to the care of their child.
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.
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.
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.
Informational support is an important pillar of psychosocial care for parents of children with cancer. Understanding the information needs of these parents may improve the provision of ...family-centered informational support. This paper aims to explore the information needs of Malaysian parents whose children have cancer.
This qualitative study was conducted among 14 parents of children with cancer and 8 healthcare providers. The parents were recruited from two urban pediatric oncology centers in Malaysia. Healthcare providers were recruited from these centers, as well as from community-based palliative care providers. In-depth interviews were conducted based on semi-structured topic guides, audio-recorded, and transcribed for thematic analysis using elements of the grounded theory approach.
Analysis revealed three themes of information needs, which were: “interaction with the healthcare system,” “care for the child at home” and “psychosocial support for parents”. Information needs on parents’ interaction with the healthcare system consisted of disease and treatment-related information, as well as health system navigation. Information needs on care for the child at home were represented by their caregiving for basic activities of daily living, medical caregiving, and psychosocial caregiving. Psychosocial support for parents included information on practical support and self-care. There were differences in priorities for information needs between parents and healthcare providers.
Meeting the information needs of parents is an important part of psychosocial care in pediatric cancer care. Informational support may empower parents in caregiving for their child. The development of suitable information resources will be invaluable for healthcare providers in supporting parents’ needs.
Malaysian parents of children diagnosed with leukemia or lymphoma stand to benefit from a comprehensive Malay-language online resource, complementing existing caregiver education practices. This ...study aimed to develop and assess the efficacy of e-Hematological Oncology Parents Education (e-HOPE), an online caregiver education resource in Malay, designed to enhance the knowledge of parents with children diagnosed with leukemia or lymphoma in Malaysia.
A user profile and topic list were established based on previous needs analysis studies. Content was developed for each identified topic. An expert panel assessed the content validity of both informational content and activity sections. Subsequently, the contents were presented via a learning management system to parents of children newly diagnosed with leukemia or lymphoma. Parents evaluated the quality of e-HOPE using the Website Evaluation Questionnaire (WEQ) after an 8-week period.
The scale content validity index (S-CVI/Ave) achieved 0.996 for informational content and 0.991 for the activity section. Sixteen parents provided evaluations of e-HOPE after an 8-week usage period. Mean WEQ scores for various dimensions ranged from 4.23 for completeness to 4.88 for relevance.
E-HOPE was meticulously designed and developed to offer Malaysian parents a Malay-language resource complementing current caregiver education practices. It exhibited strong content validity and received positive user ratings for quality. Further assessment is warranted to evaluate its effectiveness in supporting parents of children with leukemia or lymphoma. The resource is anticipated to enhance information accessibility and support for Malaysian parents facing hematological cancers in their children.
