Parent and patient knowledge and attitudes about cancer predisposition syndrome genetic testing in pediatric oncology: Understanding sociodemographic and parent-child differences
Cancer Rep (Hoboken). 2024 Sep;7(9):e2119. doi: 10.1002/cnr2.2119. ABSTRACT BACKGROUND: Cancer predisposition syndromes (CPS) impact about 10% of patients with pediatric cancer. Genetic testing (CPS-GT) has multiple benefits, but few studies have described parent and child knowledge and attitudes regarding CPS-GT decision-making. This study examined parent and patient CPS-GT decision-making knowledge and attitudes. PROCEDURE: English- or […]
Circular extrachromosomal DNA promotes tumor heterogeneity in high-risk medulloblastoma
Nat Genet. 2023 Nov 9. doi: 10.1038/s41588-023-01551-3. Online ahead of print. ABSTRACT Circular extrachromosomal DNA (ecDNA) in patient tumors is an important driver of oncogenic gene expression, evolution of drug resistance and poor patient outcomes. Applying computational methods for the detection and reconstruction of ecDNA across a retrospective cohort of 481 medulloblastoma tumors from 465 […]
The genomic landscape of familial glioma
Sci Adv. 2023 Apr 28;9(17):eade2675. doi: 10.1126/sciadv.ade2675. Epub 2023 Apr 28. ABSTRACT Glioma is a rare brain tumor with a poor prognosis. Familial glioma is a subset of glioma with a strong genetic predisposition that accounts for approximately 5% of glioma cases. We performed whole-genome sequencing on an exploratory cohort of 203 individuals from 189 […]
3D genome mapping identifies subgroup-specific chromosome conformations and tumor-dependency genes in ependymoma
Nat Commun. 2023 Apr 21;14(1):2300. doi: 10.1038/s41467-023-38044-0. ABSTRACT Ependymoma is a tumor of the brain or spinal cord. The two most common and aggressive molecular groups of ependymoma are the supratentorial ZFTA-fusion associated and the posterior fossa ependymoma group A. In both groups, tumors occur mainly in young children and frequently recur after treatment. Although […]
Current studies and future directions for medulloblastoma: A review from the pacific pediatric neuro-oncology consortium (PNOC) disease working group
Neoplasia. 2022 Dec 11;35:100861. doi: 10.1016/j.neo.2022.100861. Online ahead of print. NO ABSTRACT PMID:36516489 DOI:10.1016/j.neo.2022.100861
Characterization of an RNA binding protein interactome reveals a context-specific post-transcriptional landscape of MYC-amplified medulloblastoma
Nat Commun. 2022 Dec 6;13(1):7506. doi: 10.1038/s41467-022-35118-3. NO ABSTRACT PMID:36473869 DOI:10.1038/s41467-022-35118-3
N-myc mediated translation control is a therapeutic vulnerability in medulloblastoma
Cancer Res. 2022 Oct 20:CAN-22-0945. doi: 10.1158/0008-5472.CAN-22-0945. Online ahead of print. ABSTRACT Deregulation of N-myc is a leading cause of malignant brain tumors in children. To target N-myc-driven medulloblastoma, most research has focused on identifying genomic alterations or on the analysis of the medulloblastoma transcriptome. Here, we have broadly characterized the translatome of medulloblastoma and […]
Safety and efficacy of intraventricular immunovirotherapy with oncolytic HSV-1 for CNS cancers
Clin Cancer Res. 2022 Oct 14:CCR-22-1382. doi: 10.1158/1078-0432.CCR-22-1382. Online ahead of print. ABSTRACT PURPOSE: Oncolytic virotherapy with herpes simplex virus-1 (HSV) has shown promise for treatment of pediatric and adult brain tumors; however, completed and ongoing clinical trials have utilized intratumoral/peritumoral oncolytic HSV (oHSV) inoculation due intraventricular/intrathecal toxicity concerns. Intratumoral delivery requires an invasive neurosurgical […]
Dormant SOX9-positive cells facilitate MYC-driven recurrence of medulloblastoma
Cancer Res. 2022 Oct 11:CAN-22-2108. doi: 10.1158/0008-5472.CAN-22-2108. Online ahead of print. ABSTRACT Relapse is the leading cause of death in patients with medulloblastoma, the most common malignant pediatric brain tumor. A better understanding of the mechanisms underlying recurrence could lead to more effective therapies for targeting tumor relapses. Here, we observed that SOX9, a transcription […]
Development of GPC2-directed chimeric antigen receptors using mRNA for pediatric brain tumors
J Immunother Cancer. 2022 Sep;10(9):e004450. doi: 10.1136/jitc-2021-004450. ABSTRACT BACKGROUND: Pediatric brain tumors are the leading cause of cancer death in children with an urgent need for innovative therapies. Glypican 2 (GPC2) is a cell surface oncoprotein expressed in neuroblastoma for which targeted immunotherapies have been developed. This work aimed to characterize GPC2 expression in pediatric […]
