Purpose: Neuroblastoma (NB) is the most common extracranial solid tumor found in children. To identify significant genetic factors for the risk of NB, several genetic studies was conducted mainly for Caucasians and Europeans. However, considering racial differences, there is a possibility that genetic predispositions that contribute to the development of NB are different, and genome-wide association study has not yet been conducted on Korean NB patients.

Materials And Methods: To identify the genetic variations associated with the risk of pediatric NB in Korean children, we performed a genome-wide association analysis with 296 NB patients and 1000 unaffected controls (total n = 1,296) after data cleaning and filtering as well as imputation of non-genotyped SNPs using IMPUTE v2.3.2.

Results: After adjusting for multiple comparisons, we found 21 statistically significant SNPs associated with the risk of NB (Pcorr < 0.05) within 12 genes (RPTN, MRPS18B, LRRC45, KANSL1L, ARHGEF40, IL15RA, L1TD1, ANO7, LAMA5, OR7G2, SALL4, and NEUROG2). Interestingly, out of these, 12 markers were nonsynonymous SNPs. The SNP rs76015112 was most significantly associated with the risk of NB (p = 8.1E-23, Pcorr = 2.3E-17) and was located in the RPTN gene. In addition, significant nonsynonymous SNPs in ADGRE1 were found in patients with MYCN amplification (rs7256147, p = 2.6E-05). In high-risk group, rs7256147 was observed as a significant SNP (p = 5.9E-06).

Conclusion: Our findings might facilitate improved understanding of the mechanism of pediatric NB pathogenesis. However, functional evaluation and replication of these results in other populations are still needed.

Association Between Language, Interpreter Use, and Pediatric Surgical Outcomes.

J Pediatr Surg

January 2025

Division of Pediatric General and Thoracic Surgery, Seattle Children's Hospital, 4800 Sand Point Way NE, Seattle, WA 98105, USA; Department of Surgery, University of Washington, Box 356410, 1959 NE Pacific St, Seattle, WA 98195, USA.

Background: Inequities exist in pediatric surgical outcomes. Differential outcomes have been identified across racial groups, geography, and socioeconomic standing. However, the association between preferred language, interpreter use, and surgical outcomes is not well-studied in pediatric surgical literature.

Purpose The present study aimed to clarify the distribution pattern of carcinoma associated fibroblasts (CAFs) across pancreatic ductal adenocarcinoma (PDAC) and its prognostic prediction value. Methods Data of two cohorts were retrospectively collected from consecutive patients who underwent primary pancreatic resection from January 2015 to December 2017. We used tumor specimens to screen out the most suitable markers for the spatial distribution analysis for CAFs subpopulations.

Preventive interventions are expected to substantially improve the prognosis of patients with primary liver cancer, predominantly hepatocellular carcinoma (HCC) and cholangiocarcinoma. HCC prevention is challenging in the face of the evolving etiological landscape, particularly the sharp increase in obesity-associated metabolic disorders, including metabolic dysfunction-associated steatotic liver disease (MASLD). Next-generation anti-HCV and HBV drugs have substantially reduced, but not eliminated, the risk of HCC and have given way to new challenges in identifying at-risk patients.

Robust genetic characterization of paediatric AML has demonstrated that fusion oncogenes are highly prevalent drivers of AML leukemogenesis in young children. Identification of fusion oncogenes associated with adverse outcomes has facilitated risk stratification of patients, although successful development of precision medicine approaches for most fusion-driven AML subtypes have been historically challenging. This knowledge gap has been in part due to difficulties in targeting structural alterations involving transcription factors and in identification of a therapeutic window for selective inhibition of the oncofusion without deleterious effects upon essential wild-type proteins.
