ABSTRACT
Two percent of pediatric malignancies arise primarily in the liver; roughly 60% of these cancers are hepatoblastoma (HB). Despite the rarity of these cases, international collaborative efforts have led to the consistent histological classification and staging systems, which facilitate ongoing clinical trials. Other primary liver malignancies seen in children include hepatocellular carcinoma (HCC) with or without underlying liver disease, fibrolamellar carcinoma (FLC), undifferentiated embryonal sarcoma of the liver (UESL), and hepatocellular neoplasm not otherwise specified (HCN-NOS). This review describes principles of surgical management of malignant pediatric primary liver tumors, within the context of comprehensive multidisciplinary care.
ABSTRACT
BACKGROUND: Survival of Wilms tumor (WT) is > 90% in high-resource settings but < 30% in low-resource settings. Adapting a standardized surgical approach to WT is challenging in low-resource settings, but a local control strategy is crucial to improving outcomes. OBJECTIVE: Provide resource-sensitive recommendations for the surgical management of WT. METHODS: We performed a systematic review of PubMed and EMBASE through July 7, 2020, and used the GRADE approach to assess evidence and recommendations. RECOMMENDATIONS: Initiation of treatment should be expedited, and surgery should be done in a high-volume setting. Cross-sectional imaging should be done to optimize preoperative planning. For patients with typical clinical features of WT, biopsy should not be done before chemotherapy, and neoadjuvant chemotherapy should precede surgical resection. Also, resection should include a large transperitoneal laparotomy, adequate lymph node sampling, and documentation of staging findings. For WT with tumor thrombus in the inferior vena cava, neoadjuvant chemotherapy should be given before en bloc resection of the tumor and thrombus and evaluation for viable tumor thrombus. For those with bilateral WT, neoadjuvant chemotherapy should be given for 6-12 weeks. Neither routine use of complex hilar control techniques during nephron-sparing surgery nor nephron-sparing resection for unilateral WT with a normal contralateral kidney is recommended. When indicated, postoperative radiotherapy should be administered within 14 days of surgery. Post-chemotherapy pulmonary oligometastasis should be resected when feasible, if local protocols allow omission of whole-lung irradiation in patients with nonanaplastic histology stage IV WT with pulmonary metastasis without evidence of extrapulmonary metastasis. CONCLUSION: We provide evidence-based recommendations for the surgical management of WT, considering the benefits/risks associated with limited-resource settings.

Paediatric spontaneous pneumothorax (PSP) management continues to lack paediatric-specific guideline recommendations. There have been increasing reports of paediatric retrospective case studies supplemented by important well designed RCT (predominantly) adult studies. Taken together, these suggest that conservative management may have an increasing role to play in the management of PSP and that aspiration may have limited utility as a first line intervention. Our local experience, as part of a multicentre retrospective analysis and subsequent audit of management since, corroborates recent published data: it highlights an increasing trend towards conservative management in spontaneous pneumothorax with similar rates of recurrence, compared to intervention, and low use of aspiration with similarly low success rates. We have therefore updated our local practice guidelines and share these with readers. Specifically, we have removed aspiration in the management of primary spontaneous pneumothorax and reserved intervention for children who are clinically unstable or show evidence of increasing air leak irrespective of pneumothorax size. Whilst the success of this change in clinical practice will need to be reviewed in the next 5-10â¯years, the overall low incidence of the condition, demands a multicentre, and probably multinational, collaborative approach to allow the best chance of obtaining definitive evidence to guide clinical paediatric management.

BACKGROUND: The purpose of this study was to compare open insertion to ultrasound guided percutaneous insertion of central access catheters performed in a tertiary pediatric hospital in terms of its safety and complication rates. METHODS: This was an ethics approved prospective randomized trial of children under 16 y of age. Procedure was performed by surgeons with varying experience with percutaneous and open insertion. Primary outcome studied was complications-immediate and late. Secondary outcomes were time taken to complete procedure, conversion rates, duration of line use. RESULTS: A total of 108 patients were analyzed. Sixty-four were male. Right internal jugular vein was accessed in 97. Eighty-one lines were double lumen, 23 implantable access devices, and the rest were single lumen catheters. More than one needle puncture was needed in 22% of the cases but there were no conversions in the ultrasound group. Twelve patients needed more than one insertion to achieve optimal position of the tip. Eleven patients had immediate and late complications. Percutaneous lines lasted 45 d longer though this was not statistically significant. Operating time was 20.6% shorter with percutaneous access. Post-removal measurement of vein size by ultrasound demonstrated significant decrease in size in the open group. CONCLUSIONS: Ultrasound guided percutaneous insertion was safe. The study also demonstrated a decrease in operating times, preservation of vein size, and no increase in complication rates in the US group when performed by operators of varying expertise.

BACKGROUND: Procedural pain and anxiety in children can be poorly controlled, leading to significant short- and long-term sequelae, such as longer procedure times or future healthcare avoidance. Caregiver anxiety can exacerbate these effects. We aimed to evaluate the effect of interactive video game interventions on children's procedural pain and anxiety, including the effect of different types of video games on those outcomes. METHODS: We conducted a systematic review and meta-analysis of the effectiveness of interactive video games compared with standard care in children (0-18 yr) undergoing painful procedures. We searched the databases MEDLINE, Embase, and PsycINFO. We conducted random-effects meta-analysis using 'R' of children's procedural pain and anxiety and caregivers' anxiety. RESULTS: Of 2185 studies screened, 36 were eligible (n=3406 patients). Studies commonly involved venous access (33%) or day surgery (31%). Thirty-four studies were eligible for meta-analyses. Interactive video games appear to reduce children's procedural pain (standardised mean difference [SMD]=-0.43; 95% confidence interval [CI]: -0.67 to -0.20), anxiety (SMD=0.61; 95% CI: -0.88 to -0.34), and caregivers' procedural anxiety (SMD=-0.31; 95% CI: -0.58 to -0.04). We observed no difference between preparatory and distracting games, or between virtual reality and non-virtual reality games. We also observed no difference between interactive video games compared with standard care for most medical outcomes (e.g. procedure length), except a reduced need for restraint. Studies reported minimal adverse effects and typically had high intervention acceptability and satisfaction. CONCLUSIONS: Our findings support introducing easily available video games, such as distraction-based conventional video games, into routine practice to minimise paediatric procedural pain and child/caregiver anxiety.

Driver mutations in the CTNNB1 gene (encoding ß-catenin) are a hallmark of sporadic hepatoblastoma (HBL). Our results show that CTNNB1 circulating tumour DNA (ctDNA) is readily detected in patients diagnosed with localised HBL, with serial sampling along the course of therapy and follow up providing a sensitive mechanism to monitor tumour dynamics and response to treatment. This exciting potential for CTNNB1 ctDNA to serve as a biomarker for treatment response in HBL holds clinical value, and requires assessment in a larger cohort of mixed tumour stages and recurrent disease.

AIM: This paper describes the incidence and outcomes of childhood renal malignancies in Australia using national population-based data from the Australian Childhood Cancer Registry. METHODS: De-identified data for children (0-14 years) diagnosed with renal malignancies from 1983 to 2015 inclusive were extracted. Cause-specific (CSS) and event-free survival up to 20 years from diagnosis were estimated using the cohort method. Adjusted excess mortality hazard ratios were calculated using a multivariable flexible parametric survival model. Details relating to second primary malignancies (SPMs) were also examined. RESULTS: There were 1046 children diagnosed with renal malignancies in Australia between 1983 and 2015 (91% nephroblastoma), generating an annual age-standardised incidence rate of 8 per million children, which remained constant over the study period. CSS was 89% (95% confidence interval = 87-91%) and 88% (86-90%) at 5 and 20 years, respectively, and 5-year event-free survival was 82% (80-84%). Five-year CSS did not change over the study period and was highest for nephroblastoma (91%). Of the 94% of patients achieving remission, 15% relapsed and subsequent 5-year CSS was 49% (40%-58%). Eleven children were diagnosed with SPM (standardised incidence ratio = 2.9, 95% confidence interval = 1.6-5.3, P < 0.001), and five of them (45%) died within 5 years of the second diagnosis. CONCLUSIONS: Children treated for renal malignancies in Australia have excellent long-term survival, which is unchanged since 1983. SPMs are uncommon following treatment for childhood renal cancer but carry a poor prognosis. Relapse carries a similarly poor prognosis to SPM but is more common. These data are comparable to registry outcomes in similarly developed nations.

AIM: Neuroblastoma predominantly affects younger children and exhibits heterogeneous behaviour. This study describes incidence and outcomes for neuroblastoma using national population-based data from the Australian Childhood Cancer Registry. METHODS: Deidentified data for all children (0-14 years) diagnosed with neuroblastoma and ganglioneuroblastoma from 1983 to 2015 were extracted. Cause-specific (CSS) and event-free survival were estimated using the cohort method. Adjusted hazard ratios were calculated using a multivariable flexible parametric survival model. Other outcomes investigated included recurrence and second primary malignancies (SPMs). RESULTS: The study cohort comprised 1269 patients. Age-standardised incidence rates remained steady across the study period at approximately 9.5 per million children per year. The proportion of patients with metastatic disease at diagnosis decreased from 63% in 1983-1995 to 42% by 2006-2015 (P < 0.001). CSS and event-free survival both improved significantly over time and reached 75% (95% confidence interval (CI) = 71-79%) and 71% (95% CI = 66-75%) at 5 years post-diagnosis, respectively, for children diagnosed between 2004 and 2013. Of patients achieving full remission, 28% relapsed with subsequent 5-year CSS of only 20%. Although SPMs were rare, neuroblastoma survivors carried a fivefold increased risk compared to cancer rates in the general population (standardised incidence ratio = 5.18, 95% CI = 3.01-8.91), with 7 of the 13 patients (54%) who were diagnosed with an SPM dying within 5 years. CONCLUSIONS: CSS for childhood neuroblastoma has improved substantially over time in Australia, but still remains lower than for most other types of childhood cancer. SPMs are uncommon and carry a better prognosis than relapse of the primary tumour.

Complete microscopic tumor resection is critical for successful treatment of hepatoblastoma, and this may include when liver transplantation is required. For tumors involving the IVC or PV, complete resection should include the involved IVC or PV to ensure full tumor clearance. When this is required, the venous reconstruction at transplant or post-excision can be challenging. We present the management of an 18-month-old girl with PRETEXT Stage IV (P, V, F) hepatoblastoma and IVC involvement, where native caval resection and reconstruction was required. The preoperative staging following neoadjuvant chemotherapy was POSTTEXT Stage IV (P, V, F). An orthotopic liver transplantation was performed using a left lateral segment graft from a deceased adult donor. With native hepatectomy, retrohepatic IVC resection from just above the hepatic venous confluence to just above the entry of the right adrenal vein was performed. For caval reconstruction, a venous graft from a deceased donor was used. The graft included the lower IVC with the right common iliac vein and a short stump of the left common iliac vein. The common iliac was a perfect size match for the IVC, and the three natural ostia matched the upper cava, lower cava, and the outflow from the donor left hepatic vein. The patient had an uneventful postoperative course and remains well and disease-free 2 years after transplant with continued patency of the reconstructed cava. When indicated, a donor iliac vein graft with its natural ostia should be considered in caval reconstruction for pediatric liver transplantation.

OBJECTIVE: Surgery for paediatric cancer presents many stresses on patients and families. The authors aimed to understand the long-term impact of childhood cancer surgery on survivors and parents. METHODS: The study recruited participants from 11 Australia/New Zealand hospitals for telephone interviews. The authors used descriptive statistics to analyse participants' quantitative distress ratings and conducted thematic analysis of shared surgical experiences and needs. RESULTS: Of 32 participants (n = 17 survivors, n = 15 parents), survivors' mean age at surgery was 6.9 (SD = 5.17) and parents' children were 2.1 years old (SD = 1.41) at time of surgery. Survivors had surgery on average 15.2 years ago (SD = 6.72) and parents' children 11.5 years ago (SD = 3.94). Parents and survivors rated surgery as highly distressing. Pre-operatively, survivors recalled experiencing fear and pain mainly associated with pre-operative procedures. Post-operatively, survivors reported immobility and some lasting behavioural disturbances. Parents described pre- and intra-operative anxiety and stress and some lasting post-operative psychological disturbances. Experiences appeared to improve with clear/consistent communication from hospital staff, proximity to hospital, and with support for parents and children post-operatively. CONCLUSIONS: Surgical treatment for childhood cancer can have a lasting impact for survivors and parents. Better information provision may improve families' surgical experience whilst reducing anxiety, distress and physical discomfort.

PURPOSE: Oesophageal atresia and tracheo-oesophageal atresia require surgical repair in early infancy. These children have significant disease-related morbidity requiring frequent radiological examinations resulting in an increased malignancy risk. METHODS: A single-centre, retrospective review was performed of radiation exposure in children with OA/TOF born 2011-2015. Medical records were reviewed to determine the number and type of imaging studies involving ionising radiation exposure enabling the calculation of the estimated effective dose per child over the first year of life. RESULTS: Forty-nine children were included. Each child underwent a median of 19 (IQR 11.5-35) imaging studies, which were primarily plain radiography (median = 14, IQR 7-26.5). The overall median estimated effective dose per patient was 4.7 (IQR 3.0-9.4) mSv, with the majority of radiation exposure resulting from fluoroscopic imaging (median 3.3 mSv, IQR 2.2-6.0). 'Routine' postoperative oesophagrams showed no leak in 35/36 (97%) with the remaining study showing an insignificant leak that did not alter management. CONCLUSIONS: Careful consideration should be given to the use of imaging in OA/TOF to minimise morbidity in these vulnerable infants. Oesophagrams in children without the symptoms of anastomotic leak or stricture should be discontinued. Standardisation of monitoring protocols with regard to radiation exposure should be considered.

Post-natal growth in surgical lung conditions, such as congenital diaphragmatic hernia and oesophageal atresia with tracheo-oesophageal fistula, is often sub-optimal in the early years of life when lung growth is occurring. Whilst constitutional, behavioural and mechanical factors may contribute to poor feeding and weight gain, there is a common path of management with greater caloric supplementation that may change growth trajectories and potentially lead to better respiratory, anthropometric and cognitive outcomes. We provide simple, single page, feeding supplementation sheets in three age groups: 0-6months, 6-12months and 12-24months that have proven useful for enhancing weight gain in our patients.

BACKGROUND: An elevated neutrophil-lymphocyte ratio (NLR) has been shown to indicate poorer prognosis for adults with solid tumors and potentially represents an independent, universal adjunct prognostic factor. The value of NLR in a pediatric setting has not been evaluated. This study sought to determine the prognostic value of NLR for pediatric patients with solid tumors. METHODS: Pediatric patients with solid tumors undergoing neoadjuvant chemotherapy followed by surgery with curative intent between 2000 and 2014 were eligible for this study. A preoperative peripheral blood count within 1 month of surgery taken after recovery from recent chemotherapy was analyzed in relation to overall survival (OS) and event-free survival (EFS). RESULTS: This retrospective study enrolled 293 patients. The median age at diagnosis was 46.5 months (range 0.1-206.1 months). Males accounted for 58% of the patients. The median OS was 49 months. An NLR cutoff of 2.5 was used in the analysis. In the univariate analysis, a high NLR was associated with low OS (p = 0.001) and low EFS (p = 0.020). Other factors identified in the univariate analysis that affected survival included metastatic disease at diagnosis (p < 0.001) and tumor type (p = 0.012). The multivariate analyses showed that a high NLR was associated with low OS (p = 0.014) but not with EFS (p = 0.270). The multivariate analysis of neuroblastoma patients found that a high NLR was associated with low OS (p = 0.013). CONCLUSIONS: An elevated NLR is prognostic of a poorer outcome for pediatric patients with solid tumors and potentially represents an independent, universal adjunct prognosticator in such cases.

We aimed to assess the incidence of HAT over three eras following implementation of microvascular techniques and a customized anticoagulation protocol in a predominantly cadaveric split liver transplant program. We retrospectively reviewed pediatric liver transplants performed between April 1986 and 2016 and analyzed the incidence HAT over three eras. In E1, 1986-2008, each patient received a standard dose of 5 U/kg/h of heparin and coagulation profiles normalized passively. In E2, 2008-2012, microvascular techniques were introduced. In E3, 2012-2016, in addition, a customized anticoagulation protocol was introduced which included replacement of antithrombin 3, protein C and S, and early heparinization. A total of 317 liver transplants were completed during the study period, with a median age of 31.7 months. In E1, 22% of grafts were cadaveric in situ split grafts, while the second and third eras used split grafts in 59.0% and 64.9% of cases, respectively. HAT occurred in 9.5% in the first era, 11.5% (P=.661) in the second, and dropped to 1.8% in the third era (P=.043). A routine anticoagulation protocol has significantly reduced the incidence of HAT post-liver transplantation in children in a predominantly cadaveric in situ split liver transplant program.

BACKGROUND: Intussusception is a common abdominal emergency in children with significant morbidity. Prompt diagnosis and management reduces associated risks and the need for surgical intervention. Despite widespread agreement on the use of contrast enema as opposed to surgery for initial management in most cases, debate persists on the appropriate contrast medium, imaging modality, pharmacological adjuvant, and protocol for delayed repeat enema, and on the best approach for surgical management for intussusception in children. OBJECTIVES: To assess the safety and effectiveness of non-surgical and surgical approaches in the management of intussusception in children. SEARCH METHODS: We searched the following electronic databases: Cochrane Central Register of Controlled Trials (CENTRAL; 2016, Issue 8) in the Cochrane Library; Ovid MEDLINE (1950 to September 2016); Ovid Embase (1974 to September 2016); Science Citation Index Expanded (via Web of Science) (1900 to September 2016); and BIOSIS Previews (1969 to September 2016).We examined the reference lists of all eligible trials to identify additional studies. To locate unpublished studies, we contacted content experts, searched the World Health Organization International Clinical Trials Registry Platform (ICTRP) and ClinicalTrials.gov (September 2016), and explored proceedings from meetings of the British Association of Paedatric Surgeons (BAPS), the American Soceity of Pediatric Surgery, and the World Congress of Pediatric Surgery. SELECTION CRITERIA: We included all randomised controlled trials comparing contrast media, imaging modalities, pharmacological adjuvants, protocols for delayed repeat enema, and/or surgical approaches for the management of intussusception in children. We applied no language, publication date, or publication status restrictions. DATA COLLECTION AND ANALYSIS: Two review authors independently conducted study selection and data extraction and assessed risk of bias using a standardised form. We resolved disagreements by consensus with a third review author when necessary. We reported dichotomous outcomes as risk ratios (RRs) with 95% confidence intervals (CIs). We analysed data on an intention-to-treat basis and evaluated the overall quality of evidence supporting the outcomes by using GRADE criteria. MAIN RESULTS: We included six randomised controlled trials (RCTs) with a total of 822 participants. Two trials compared liquid enema reduction plus glucagon versus liquid enema alone. One trial compared liquid enema plus dexamethasone versus liquid enema alone. Another trial compared air enema plus dexamethasone versus air enema alone, and two trials compared use of liquid enema versus air enema. We identified three ongoing trials.We judged all included trials to be at risk of bias owing to omissions in reported methods. We judged five of six trials as having high risk of bias in at least one domain. Therefore, the quality of the evidence (GRADE) for outcomes was low. Interventions and data presentation varied greatly across trials; therefore meta-analysis was not possible for most review outcomes. Enema plus glucagon versus enema alone It is uncertain whether use of glucagon improves the rate of successful reduction of intussusception when compared with enema alone (reported in two trials, 218 participants; RR 1.09, 95% CI 0.94 to 1.26;low quality of evidence). No trials in this comparison reported on the number of children with bowel perforation(s) nor on the number of children with recurrent intussusception. Enema plus dexamethasone versus enema alone Use of the adjunct, dexamethasone, may be beneficial in reducing intussusception recurrence with liquid or air enema (two trials, 299 participants; RR 0.14, 95% CI 0.03 to 0.60; low quality of evidence). This equates to a number needed to treat for an additional beneficial outcome of 13 (95% CI 8 to 37). It is uncertain whether use of the adjunct, dexamethasone, improves the rate of successful reduction of intussusception when compared with enema alone (reported in two trials, 356 participants; RR 1.01, 95% CI 0.92 to 1.10;low quality of evidence). Air enema versus liquid enema Air enema may be more successful than liquid enema for reducing intussusception (two trials, 199 participants; RR 1.28, 95% CI 1.10 to 1.49; low quality of evidence). This equates to a number needed to treat for an additional beneficial outcome of 6 (95% CI 4 to 19). No trials in this comparison reported on the number of children with bowel perforation(s) or on the number of children with recurrent intussusception nor any intraoperative complications, such as bowel perforation, or other adverse effects. Only one trial reported postoperative complications, but owing to the method of reporting used, a quantitative analysis was not possible. We identified no studies that exclusively evaluated surgical interventions for management of intussusception. AUTHORS' CONCLUSIONS: This review identified a small number of trials that assessed a variety of interventions. All included trials provided evidence of low quality and were subject to serious concerns about imprecision, high risk of bias, or both. Air enema may be superior to liquid enema for successfully reducing intussusception in children; however, this finding is based on a few studies including small numbers of participants. Dexamethasone as an adjuvant may be more effective in reducing intussusception recurrence rates following air enema or liquid enema, but these results are also based on a few studies of small numbers of participants. This review highlights several points that need to be addressed in future studies, including reducing the risk of bias and including relevant outcomes. Specifically, surgical trials are lacking, and future research is needed to address this evidence gap.

Appendicectomy has remained the treatment of choice for appendicitis for over a century and is the most commonly performed emergency operation in children. However, emerging evidence suggests that appendicectomy may not always be necessary in uncomplicated appendicitis, with early paediatric trials demonstrating that antibiotic-only therapy can be safe and effective. Further rigorously designed and appropriately powered studies are necessarily to establish the place of non-operative management of uncomplicated appendicitis in the future.

This study is to determine the association of ambulatory pH monitoring (24hr pH) with symptoms of gastroesophageal reflux and its other investigations. The clinical and epidemiological profiles of subjects referred for reflux disorders are also studied. Symptoms or group of symptoms, profiles and prior investigations of 1259 consecutive pediatric subjects (with 1332 24hr pH studies performed) referred for evaluation of reflux disorders between 1988 and 2012 were retrospectively studied. Chi-square or fisher exact test was used for hypothesis testing, student t-test for the comparison of means and the Wilcoxon rank-sum test for comparing medians of continuous variables. Gastroesophageal reflux disease (GERD), defined as reflux causing major symptoms and complications, was diagnosed in 57.5% subjects of the total sample. Forty-three percent were girls and 56.7% were boys. The most common age group was between 4 months and 2 years (51.2%). Vomiting (64.4%) and irritability (74%) were the most common symptoms with the neurological conditions (23.2%) being the most frequent underlying condition. The parameters used in 24hr pH were significantly higher in those diagnosed with GERD (P < 0.0001). The prevalence of GERD was found to be significantly higher when both gastrointestinal and respiratory symptoms were present (P = 0.008) at 66.4% than when compared with gastrointestinal (56.5%) and respiratory (52.2%) symptoms in isolation. Symptoms alone were not reliable in diagnosing GERD. Only 57.5% had GERD among patients referred for reflux disorders. 24hr pH is reliable and should be considered routine in reflux disorders, as it identifies patients with pathologic reflux and avoids a needless surgery.
