    (Oxford University Press, 2022) Bartlett, Allison L.; Lane, Adam; Chaney, Brooklyn; Yanez Escorza, Nancy; Black, Katie; Cochrane, Anne; Minturn, Jane; Bartels, Ute; Warren, Kathy; Hansford, Jordan; Ziegler, David; Diez, Blanca; Goldman, Stewart; Packer, Roger; Kieran, Mark; DeWire-Schottmiller, Mariko; Erker, Craig; Monje-Deisseroth, Michelle; Wagner, Lars; Koschmann, Carl; Dorris, Kathleen; Shih, Chie-Schin; Hassall, Tim; Fisher, Paul; Wang, Stacie S.; Tsui, Karen; Sevlever, Gustavo; Zhu, Xiaoting; Dexheimer, Phillip; Asher, Anthony; Fuller, Christine; Drissi, Rachid; Jones, Blaise; Leach, James; Fouladi, Maryam; Pediatrics, School of Medicine
    Background: Children ≤36 months with diffuse intrinsic pontine glioma (DIPG) have increased long-term survival (LTS, overall survival (OS) ≥24 months). Understanding distinguishing characteristics in this population is critical to improving outcomes. Methods: Patients ≤36 months at diagnosis enrolled on the International DIPG Registry (IDIPGR) with central imaging confirmation were included. Presentation, clinical course, imaging, pathology and molecular findings were analyzed. Results: Among 1183 patients in IDIPGR, 40 were eligible (median age: 29 months). Median OS was 15 months. Twelve patients (30%) were LTS, 3 (7.5%) very long-term survivors ≥5 years. Among 8 untreated patients, median OS was 2 months. Patients enrolled in the registry but excluded from our study by central radiology review or tissue diagnosis had median OS of 7 months. All but 1 LTS received radiation. Among 32 treated patients, 1-, 2-, 3-, and 5-year OS rates were 68.8%, 31.2%, 15.6% and 12.5%, respectively. LTS had longer duration of presenting symptoms (P = .018). No imaging features were predictive of outcome. Tissue and genomic data were available in 18 (45%) and 10 patients, respectively. Among 9 with known H3K27M status, 6 had a mutation. Conclusions: Children ≤36 months demonstrated significantly more LTS, with an improved median OS of 15 months; 92% of LTS received radiation. Median OS in untreated children was 2 months, compared to 17 months for treated children. LTS had longer duration of symptoms. Excluded patients demonstrated a lower OS, contradicting the hypothesis that children ≤36 months with DIPG show improved outcomes due to misdiagnosis.

    Characteristics of patients ≥10 years of age with diffuse intrinsic pontine glioma: a report from the International DIPG/DMG Registry
    (Oxford University Press, 2022) Erker, Craig; Lane, Adam; Chaney, Brooklyn; Leary, Sarah; Minturn, Jane E.; Bartels, Ute; Packer, Roger J.; Dorris, Kathleen; Gottardo, Nicholas G.; Warren, Katherine E.; Broniscer, Alberto; Kieran, Mark W.; Zhu, Xiaoting; White, Peter; Dexheimer, Phillip J.; Black, Katie; Asher, Anthony; DeWire, Mariko; Hansford, Jordan R.; Gururangan, Sridharan; Nazarian, Javad; Ziegler, David S.; Sandler, Eric; Bartlett, Allison; Goldman, Stewart; Shih, Chie-Schin; Hassall, Tim; Dholaria, Hetal; Bandopadhayay, Pratiti; Samson, Yvan; Monje, Michelle; Fisher, Paul G.; Dodgshun, Andrew; Parkin, Sarah; Chintagumpala, Murali; Tsui, Karen; Gass, David; Larouche, Valerie; Broxson, Emmett; Garcia Lombardi, Mercedes; Shiqi Wang, Stacie; Ma, Jie; Hawkins, Cynthia; Hamideh, Dima; Wagner, Lars; Koschmann, Carl; Fuller, Christine; Drissi, Rachid; Jones, Blaise V.; Leach, James; Fouladi, Maryam; Pediatrics, School of Medicine
    Background: Diffuse intrinsic pontine gliomas (DIPG) generally occur in young school-age children, although can occur in adolescents and young adults. The purpose of this study was to describe clinical, radiological, pathologic, and molecular characteristics in patients ≥10 years of age with DIPG enrolled in the International DIPG Registry (IDIPGR). Methods: Patients ≥10 years of age at diagnosis enrolled in the IDIPGR with imaging confirmed DIPG diagnosis were included. The primary outcome was overall survival (OS) categorized as long-term survivors (LTS) (≥24 months) or short-term survivors (STS) (<24 months). Results: Among 1010 patients, 208 (21%) were ≥10 years of age at diagnosis; 152 were eligible with a median age of 12 years (range 10-26.8). Median OS was 13 (2-82) months. The 1-, 3-, and 5-year OS was 59.2%, 5.3%, and 3.3%, respectively. The 18/152 (11.8%) LTS were more likely to be older (P < .01) and present with longer symptom duration (P < .01). Biopsy and/or autopsy were performed in 50 (33%) patients; 77%, 61%, 33%, and 6% of patients tested had H3K27M (H3F3A or HIST1H3B), TP53, ATRX, and ACVR1 mutations/genome alterations, respectively. Two of 18 patients with IDH1 testing were IDH1-mutant and 1 was a LTS. The presence or absence of H3 alterations did not affect survival. Conclusion: Patients ≥10 years old with DIPG have a median survival of 13 months. LTS present with longer symptom duration and are likely to be older at presentation compared to STS. ATRX mutation rates were higher in this population than the general DIPG population.

    Outc-08. Implementing Social Determinant of Health Data Collection for Pediatric, Adolescent and Young Adult Neuro-Oncology Patients in the Clinical Trial Consortia Setting: Progress and Challenges
    (Oxford University Press, 2023-06-12) Puthenpura, Vidya; Bona, Kira; Cooney, Tab; Coven, Scott; Davidson, Tom; Fouladi, Maryam; Kline, Cassie; Leary, Sarah; Mueller, Sabine; Green, Adam; Marks, Asher; Pediatrics, School of Medicine
    Adverse social determinants of health (SDoH) are associated with decreased survival and increased long-term complications amongst pediatric and adolescent and young adult (AYA) neuro-oncology patients. These outcome disparities are in part due to inferior access to clinical trials and comprehensive, multidisciplinary care. SDoH including food insecurity, housing instability, inability to pay for utilities, and personal safety issues have been shown to negatively impact therapy adherence and exacerbate survival disparities. As such, efforts to improve health equity must include evaluating and addressing SDoH at diagnosis. Existing literature has been limited by a reliance on proxy measures of adverse SDOH such as neighborhood or census area-level socioeconomic status data, which poorly reflect individual circumstances. There is a complex interplay between neighborhood and personal socioeconomic status that has not been extensively studied and is poorly understood. In addition, socioeconomic status is only one component of SDoH. No validated tool currently exists to assess SDoH amongst pediatric and AYA cancer patients. It is imperative that multicenter clinical trials collect SDoH data to inform both trial design and interpretation of results. These data will be important to understanding and identifying patterns in tumor and toxicity incidence, as well as understanding the burden on families in adhering to trial therapies. Based on our previous work, we will present the importance of incorporating SDoH data collection within the clinical trial consortia setting. In addition, we will review the development of a comprehensive SDoH questionnaire and discuss facilitators and barriers to the incorporation of SDoH questionnaires into multicenter clinical trials and offer solutions based on our experience.
