    Abstract Background: Data are limited and conflicting regarding loss of immunity in childhood cancer survivors who did not undergo hematopoietic stem cell transplantation. The purpose of this retrospective, single center study is to provide further data to help build unifying revaccination guidelines post-chemotherapy in childhood cancer survivors not having undergone hematopoietic stem cell transplantation.
    Methods: This retrospective study included 28 childhood cancer survivors, 14 males and 14 females, whose treatment consisted of at least 3 months of chemotherapy and with confirmation of completing their primary vaccination series prior to therapy. The rate of vaccine titer seropositivity for cancer survivors was compared with the expected general population, based on long-term studies of anti-body persistence.
    Results: Decreased seropositivity for measles, mumps, rubella, varicella, tetanus, and hepatitis B was found in patients across all categories of malignancy compared with the general population. However, tetanus was not statistically significant. Results were more pronounced for those with hematological malignancies.
    Conclusions: This study indicates that pediatric cancer survivors, especially those with hematological malignancies, may have greater loss of protective antibodies from primary vaccinations. Further studies are needed to provide guidelines for revaccination of both hematologic malignancies and solid tumor childhood cancer survivors who did not undergo hematopoietic stem cell transplantation.

    Abstract Neurofibromatosis type 1 (NF1) is a genetic condition commonly associated with a predisposition to tumor development. Affected individuals have an increased risk of benign and malignant tumors of the central and peripheral nervous system. Though pediatric patients with NF1 have an increased risk of tumors such as optic gliomas and neurofibromas during childhood, neuroblastic tumors are less often observed in this population. We report a rare case of a 5-year-old female with ganglioneuroblastoma intermixed and known history of NF1 and review the existing literature on the occurrence of ganglioneuroblastoma in pediatric patients with NF1.

    Abstract Biologic therapies have revolutionized the treatment of immune-mediated diseases. They are generally well tolerated; however, there are reports of malignancies associated with the use of these drugs. This case is of an adolescent with refractory Crohn's disease treated with ustekinumab, who subsequently developed Ewing's sarcoma. Patients treated with ustekinumab have reportedly developed B cell lymphoma, epithelioid sarcoma, as well as cancer of the lung, esophagus, ovary, testis, kidney, and thyroid. However, this is the first documented case of a patient treated with ustekinumab to develop Ewing sarcoma.

    Abstract Trisomy 21 is a common congenital disorder with well-documented clinical manifestations, including an increased risk for the transient myeloproliferative disorder as a neonate and leukemia in childhood and adolescence. Transient myeloproliferative disorder is only known to occur in hematopoietic cells with trisomy 21. Children with mosaic trisomy 21 also have a risk for hematological malignancies. We present a nondysmorphic neonate, with a negative noninvasive prenatal screening of maternal blood for trisomy 21, who came to medical attention because of ruddy skin. He was found to have mild polycythemia, thrombocytopenia, and developed peripheral blasts. His clinical presentation was consistent with transient myeloproliferative disorder, which is only seen with trisomy 21. Cytogenetic studies of peripheral blood are positive for mosaic trisomy 21.

    Abstract Introduction: Down syndrome (DS) is the most common multiple malformation syndrome in humans and is associated with an increased risk of childhood malignancy, particularly leukemia. Incidence of brain tumors in patients with DS is limited to sporadic cases. We report the first case of a RELA fusion-positive ependymoma in a 3-year-old boy with DS.
    Case presentation: Imaging prompted by new left-sided hemiparesis demonstrated an 8-cm hemorrhagic right temporal-parietal mass. Subsequent image-complete resection confirmed a RELA fusion-positive anaplastic ependymoma with 90% OLIG2 staining. Postoperatively, the patient, unfortunately, experienced fatal recurrence and drop metastases with leptomeningeal involvement.
    Conclusion: To our knowledge, this is the first reported case of a confirmed RELA fusion-positive ependymoma in a child with DS. We discuss this finding in the context of intracranial tumors in children with DS, as well as the finding of 90% positive OLIG2 expression and its potential as a prognostic marker.

    Abstract Introduction Given their risk for late effects and early mortality, childhood/adolescent cancer survivors (CACSs) should receive longitudinal monitoring and care. The Southern California Pediatric and Adolescent Cancer Survivorship (SC-PACS) consortium was established in February 2017 to combine resources and expertise across seven participating survivorship programs. Its over-arching objective is to address the unique needs of its demographically diverse CACS population through collaborative survivorship research and care initiatives. The first SC-PACS study was an assessment of survivorship needs and evaluation of current services as reported by CACSs and their parents/primary care givers (PPCGs) receiving survivorship care at consortium sites. Methods As an initial investigation, a cross-sectional survey for CACSs and their parents/primary care givers was conducted. The goal was to enroll 10 CACSs and 10 PPCGs from each of the seven institutions (total of 140 participants). The eligibility criteria for CACSs were age ≥13 years at the time of enrollment, >2 years from the end of treatment, sufficient cognitive function to complete the survey, and English or Spanish language proficiency. For CACSs <13 years old, their PPCGs completed the survey. This was a convenience sample using frequencies and proportions to describe participant characteristics and survey responses, which were entered into a Research Electronic Data Capture (REDCap) database. Results Across the consortium, of the recruitment target of 140 participants (CACSs, n=70; PPCGs, n=70), 127 (90.7%) participants were enrolled. Of the 127 participants enrolled, 65 (51.2%) were CACSs and 62 (48.8%) were PPCGs. The majority of participants were female (51.2%), were Hispanic (62.2%), spoke English as the primary language at home (57.5%), and were diagnosed between one to four years of age (45.7%). Information considered most important by both CACSs and PPCGs was related to cancer diagnosis (90.8%) and future risks as a result of cancer treatment received (98.0%). Overall, 78% of CACSs and PPCGs found the survivorship information (treatment summary) useful, and 83% felt that they received the right amount of information about their cancer. Conclusion Our aim was to obtain baseline data that would characterize our CACS population, inform consortium priorities, and establish a collaborative research platform. The ultimate goal of the consortium is to develop a comprehensive survivorship care approach that addresses the most important needs of cancer survivors in our catchment area and promotes best practice interventions. Future plans are to expand the needs assessment survey to obtain a wider representation of the survivor population at SC-PACS institutions, helping create strategies to improve cancer-specific education, delivery of treatment summary, and access to community resources for this demographically and socioeconomically diverse population.

    Abstract Background: Tuberous sclerosis complex (TSC) predisposes to the development of benign lesions within multiple organ systems, including the brain, kidneys, heart, lungs, and skin. Disease mortality is due to space-occupying subependymal giant cell astrocytomas and hemorrhage-prone renal angiomyolipomas. The recent use of mTORC1 inhibitors, such as everolimus, has allowed for direct targeting of TSC-associated mass lesions without apparent effect on surrounding tissues. Because of the mechanism of these drugs, there is reason to believe that these effects are not durable and that there may be need for continued long-term maintenance therapy.
    Case-diagnosis/treatment: We present a case of TSC-associated mass lesions that were ill-suited for definitive surgical therapy. The patient was started on everolimus, however due to a complex social situation treatment was discontinued and ultimately resumed many months later. Radiologic studies acquired before and after each period of therapeutic onset/cessation reveal the dramatic but impermanent effects of mTORC1 inhibition.
    Conclusions: While everolimus provides a non-invasive way to treat TSC-associated lesions, patients may require lifelong therapy. When termination of therapy is considered, the patient should be made aware of the expectation of potentially dramatic increases in lesion size. If consideration is to be given to definitive surgical therapy, it should be pursued while the patient is still on the medication, or at least soon after treatment is halted.

    Abstract For this study, 118 children with standard-risk acute lymphoblastic leukemia (ALL) were given randomized assignments to receive native or pegylated Escherichia coli asparaginase as part of induction and 2 delayed intensification phases. Patients treated with pegaspargase had more rapid clearance of lymphoblasts from day 7 and day 14 bone marrow aspirates and more prolonged asparaginase activity than those treated with native asparaginase. In the first delayed intensification phase, 26% of native asparaginase patients had high-titer antibodies, whereas 2% of pegaspargase patients had those levels. High-titer antibodies were associated with low asparaginase activity in the native arm, but not in the pegaspargase arm. Adverse events, infections, and hospitalization were similar between arms. Event-free survival at 3 years was 82%. A population pharmacodynamic model using the nonlinear mixed effects model (NONMEM) program was developed that closely fit the measured enzyme activity and asparagine concentrations. Half-lives of asparaginase were 5.5 days and 26 hours for pegaspargase and native asparaginase, respectively. There was correlation between asparaginase enzymatic activity and depletion of asparagine or glutamine in serum. In cerebrospinal fluid asparagine, depletion was similar with both enzyme preparations. Intensive pegaspargase for newly diagnosed ALL should be tested further in a larger population.
