Diagnosis Of Mosaic Rasopathy In A Child With Rhabdomyosarcoma, Meagan Vacek, Paige Johnson, Midhat S. Farooqi, Kristi M. Canty, Dihong Zhou, Brendan Lanpher, Wendy Allen-Rhoades, Erin M. Guest

Posters

Background: Phacomatosis pigmentokeratotica (PPK) is a subtype of epidermal nevus syndrome characterized by the co-existence of a sebaceous nevus and a speckled lentiginous nevus and described in approximately 30 cases in literature. PPK is now recognized as a mosaic RASopathy due a postzygotic mutation in the Ras-Raf-MEK-ERK pathway. RAS variants are also known to contribute to tumorigenesis, in some pediatric cancers, including rhabdomyosarcoma. Objective: Describe the presentation and evaluation of a child with pelvic rhabdomyosarcoma and evolving skin lesions found to have a rare mosaic-RASopathy. Design/Method: Case Report Results: The patient is a former 32-week premature female who presented to …

Increasing Palliative Care Team Involvement In Pediatric Hematopoietic Stem Cell Transplant Patients, Meagan Vacek, Lisa Tarbell, Melissa List, Erin Hall, Jennifer Linebarger, Kelstan Ellis, Gina Jones, Joel Thompson

Posters

Background: Palliative care facilitates communication, helps with physical and psychological symptom management, and assists in goals of care and advance care planning discussions.1 Multiple organizations, including the American Academy of Pediatrics and American Society of Clinical Oncology encourage palliative care engagement and their involvement with hematopoietic stem cell transplant (HSCT) patients has been shown to be beneficial as HSCT is associated with a high degree of morbidity and possible mortality.2-3 Objective: To increase the number of PaCT consults for patients receiving HSCT for our targeted diagnoses from 48% to 75% by December 2023. Methods: Chart review was conducted for patients …

Acute lymphoblastic leukemia in infants (iALL) is a high-risk subtype of childhood leukemia, with poor survival outcomes despite intensive therapies. Rearrangement of KMT2A (KMT2A-r) on chromosome 11q23 is the most frequent cytogenetic abnormality in iALL, occurring in 70% of cases. KMT2A-r is associated with chemotherapy resistance, early relapse, and rapid leukemic progression, all of which contribute to poor survival outcomes. The most common KMT2A-r in iALL is KMT2A::AFF1 (MLL::AF4), derived from t(4;11)(q21;23) and arises in utero as shown in multiple clinical studies. Infant ALL’s cell of origin is thought to be a very early hematopoietic precursor, with transcriptomic studies of …

Psychosocial Needs Of Pediatric Patients With Cancer Predisposition Syndromes: Standardized Screening Needed, Meredith Ehrhardt, Mirae Fornander, Rachel Moore

Posters

Introduction Cancer predisposition syndromes (CPS; e.g., Li-Fraumeni syndrome, Von Hippel-Lindau syndrome) require routine, standardized medical monitoring with accompanying unique, complex psychosocial needs (e.g., family medical needs). Despite limited research within pediatric populations, emerging literature has begun to support the benefit of routine psychosocial screening in this population. Very few pediatric CPS clinics with dedicated psychosocial care (i.e., psychology) exist in the U.S. and there is currently no standard of care for psychosocial support of CPS patients. This study aims to better understand the psychosocial needs of pediatric CPS patients and support the need for a standardized psychosocial screening protocol among …

Treatment Of Recurrent Wilms Tumor With Irinotecan/Temozolomide, Meagan Vacek, Terrie Flatt

Posters

Background: Despite improvement in relapse free survival (RFS) in recurrent Wilms tumor, the 4-year RFS rate for patients treated with vincristine/dactinomycin/doxorubicin is approximately 40%. Ifosfamide, carboplatin and etoposide are commonly used in relapsed solid tumors, but have significant toxicities and require hospital admission for administration. Our patient focused on quality of life, and this led to exploration of other treatment options. Objective: Describe a case of multiply relapsed Wilms tumor with management on oral irinotecan/temozolomide for improved quality of life and remission for almost 1 year. Design/Method: Case Report Results: The patient is an 11-year-old female diagnosed with Wilms tumor …

Memory T Cell Populations In Human Leukemia, Sara Mcelroy, Fang Tao, John Szarejko, John M. Perry

Posters

Background Incorporating the immune system into cancer management is an area of robust research. Treatment modalities aimed at activating cytotoxic T cells against malignancies include immune checkpoint inhibitors, bispecific T-cell engagers, and chimeric antigen receptor (CAR) tumor-specific T cells. Most anti-cancer T cell research is narrowly focused, but knowledge about the nature of diverse sub-populations of T cells in cancer, particularly memory T cells, is vital prior to potential incorporation into therapies. T memory stem cells (Tscm) are of interest due to their longevity and powerful abilities of self-renewal and creating the full spectrum of memory CD8+ T cells, including …

Longitudinal Analysis Of Myocardial Function Using Strain In Patients Receiving Cardiotoxic Chemotherapy, Anmol Goyal, Amulya Buddhavarapu, Kayla Simpson, Nataliya Kibiryeva, Wendy Hein, Joy M. Fulbright, Sanket Shah

Posters

Background:

Chemotherapy-related cardiotoxicity (CTRC) is associated with significant morbidity and mortality in long-term cancer survivors. Left ventricular [LV] Global longitudinal strain (GLS) is a sensitive parameter that can be used for earlier detection of contractile function changes in these patients. Recent literature suggested certain genotypes may influence CTRC. Our goal was to assess longitudinal myocardial function and identify any correlation between certain genetic variations and LV function regarding CTRC in our pediatric population.

Methods:

50 subjects ≥10 years of age who have survived >2 years after completion of cancer treatment were enrolled out of which 29 subjects agreed for genetic …

Neuroblastoma In Adolescents And Children Older Than 10 Years: Unusual Clinicopathologic And Biologic Features, Laura Mccarthy, Katherine Chastain, Terrie Flatt, Eugenio Taboada, Robert E. Garola, John Herriges, Linda D. Cooley, Atif Ahmed

Posters

This poster describes four cases of neuroblastoma diagnosed since 2008 in children greater than 10 years and presents their clinical, histologic and biologic features, emphasizing unusual clinicopathologic characteristics and the role of DNA microarray analysis and Next Generation Sequencing in their management.

Review Of Karyotypic Data From Low Grade Glial Brain Tumors, Specifically Pilocytic Astrocytomas, And Correlation Of Genetic Aberrations With Tumor Recurrence., Linda D. Cooley, Scott C. Smith, Lisa Warren, Melissa Gener, Kevin Ginn, John Herriges

Posters

Abstract: Brain tumors are the most common solid tumor of childhood. Approximately 50% of pediatric CNS tumors are low grade gliomas (WHO grade I or II) and Pilocytic astrocytoma (PA) is the most common accounting for 33% of all gliomas in children 0-14 years and ~18% of all childhood brain tumors. Prognosis with this slow-growing tumor is excellent; 10 year overall survival of ~95%. However, event free survival averages ~50%. Patient age and extent of tumor resection are key prognostic factors; tumor location and size impact resection and outcome. Histopathological features indicate PA is a benign tumor and rarely are …
