Abstract Intrathecal (IT) chemotherapy, given via lumbar puncture (LP) or an intracerebroventricular (ICV) device has become a safe and effective way to deliver chemotherapy into the cerebrospinal fluid (CSF) space. The blood brain barrier makes treating tumors with CSF dissemination difficult with systemic chemotherapy alone. IT chemotherapy is often necessary for tumors which disseminate into the CSF space including embryonal tumors and choroid plexus carcinomas. It is also used for relapsed or recurrent tumors. Giving IT chemotherapy via an ICV device instead of via an LP can be preferable as it requires no deep sedation and allows for more uniform drug distribution. Drugs given IT include methotrexate, cytarabine, hydrocortisone, etoposide, and topotecan. ICV devices can be placed in patients with adequate CSF flow and a flow study can be done if needed to confirm. Accessing the ICV device for administration of chemotherapy is typically done by a physician or nurse practitioner using sterile technique. Our institution has had success using music therapy and child life specialists for assistance with coping during the procedure as patients are awake. The procedure has few complications the most common being infection usually with skin flora. It can also cause nausea and headache. There are few long term risks.

Numerous papers have reported altered expression patterns of Ras and/or ShcA proteins in different types of cancers. Their level can be potentially associated with oncogenic processes. We analyzed samples of pediatric brain tumors reflecting different groups such as choroid plexus tumors, diffuse astrocytic and oligodendroglial tumors, embryonal tumors, ependymal tumors, and other astrocytic tumors as well as tumor malignancy grade, in order to characterize the expression profile of Ras, TrkB, and three isoforms of ShcA, namely, p66Shc, p52Shc, and p46Shc proteins. The main aim of our study was to evaluate the potential correlation between the type of pediatric brain tumors, tumor malignancy grade, and the expression patterns of the investigated proteins.

Betweeness Centrality

Abstract INTRODUCTION Treatments for pediatric brain tumors (PBT) are neurotoxic and lead to long-term deficits that are driven by the perturbation of underlying white matter (WM). It is unclear if and how treatment may impair WM connectivity across the entire brain. METHODS Magnetic resonance images from 41 PBT survivors (mean age: 13.19 years, 53% M) and 41 typically developing (TD) children (mean age: 13.32 years, 51% M) were analyzed. Image reconstruction, segmentation, and node parcellation were completed in FreeSurfer. DTI maps and probabilistic streamline generation were completed in MRtrix3. Connectivity matrices were based on the number of streamlines connecting two nodes and the mean DTI (FA) index across streamlines. We used graph theoretical analyses to define structural differences between groups, and random forest (RF) analyses to identify hubs that reliably classify PBT and TD children. RESULTS For survivors treated with radiation, betweeness centrality was greater in the left insular (p < 0.000) but smaller in the right pallidum (p < 0.05). For survivors treated without radiation (surgery-only), betweeness centrality was smaller in the right interparietal sulcus (p < 0.05). RF analyses showed that differences in WM connectivity from the right pallidum to other parts of the brain reliably classified PBT survivors from TD children (classification accuracy = 77%). CONCLUSIONS The left insular, right pallidum, and right inter-parietal sulcus are structurally perturbed hubs in PBT survivors. WM connectivity from the right pallidum is vulnerable to the long-term effects of treatment for PBT.

OBJECT Pediatric brain tumors may be associated with medically intractable epilepsy for which surgery is indicated. The authors sought to evaluate the efficacy of epilepsy surgery for seizure control in pediatric patients with brain tumors. METHODS The authors performed a retrospective review of consecutive patients undergoing resective epilepsy surgery related to pediatric brain tumors at Miami Children’s Hospital between June 1986 and June 2014. Time-to-event analysis for seizure recurrence was performed; an “event” was defined as any seizures that occurred following resective epilepsy surgery, not including seizures and auras in the 1st postoperative week. The authors analyzed several preoperative variables to determine their suitability to predict seizure recurrence following surgery. RESULTS Eighty-four patients (47 males) with a mean age (± standard deviation) of 8.7 ± 5.5 years (range 0.5–21.6 years) were included. The study included 39 (46%) patients with gliomas, 20 (24%) with dysembryoplastic neuroepithelial tumors (DNETs), 14 (17%) with gangliogliomas, and 11 (13%) with other etiologies. Among the patients with gliomas, 18 were classified with low-grade glioma, 5 had oligodendroglioma, 6 had uncategorized astrocytoma, 3 had pilocytic astrocytoma, 3 had pleomorphic xanthoastrocytoma, 3 had glioblastoma, and 1 had gliomatosis cerebri. Seventy-nine (94.0%) resections were guided by intraoperative electrocorticography (ECoG). The mean time (± standard deviation) to seizure recurrence was 81.8 ± 6.3 months. Engel Class I outcome was achieved in 66 (78%) and 63 (75%) patients at 1 and 2 years’ follow-up, respectively. Patients with ganglioglioma demonstrated the highest probability of long-term seizure freedom, followed by patients with DNETs and gliomas. In univariate analyses, temporal location (HR 1.75, 95% CI 0.26–1.27, p = 0.171) and completeness of resection (HR 1.69, 95% CI 0.77–3.74, p = 0.191) demonstrated a trend toward a longer duration of seizure freedom. CONCLUSIONS ECoG-guided epilepsy surgery for pediatric patients with brain tumors is highly effective. Tumors located in the temporal lobe and those in which a complete ECoG-guided resection is performed may result in a greater likelihood of long-term seizure freedom.

9531 Background: Follow-up guidelines identify supratentorial tumor location as a risk factor for poor neurocognitive outcomes during childhood; yet few studies have systematically compared long-term cognitive outcomes between adult survivors of childhood infratentorial and supratentorial brain tumors. Methods: Neurocognitive functions were evaluated in 130 adult survivors of pediatric brain tumors (58 supratentorial and 72 infratentorial, mean [SD] current age = 27.4 years [5.2], age at diagnosis = 8.6 years [4.6], and time since diagnosis = 18.8 years [4.8]) participating in the SJLIFE long-term follow-up protocol. Age-adjusted standard scores for measures of intelligence, attention, memory, processing speed, and executive functioning were calculated, with clinical impairment defined as scores <10th percentile. Odds ratios (OR) and 95% confidence intervals (CI) were calculated using multivariable logistic regression models to examine associations between neurocognitive functions and tumor location. Results: As a group, survivors performed below average across multiple neurocognitive domains, including full scale IQ (mean=88.1; SD=18.2), with 34% demonstrating impaired IQ. Survivors of infratentorial tumors were more likely to be impaired on measures of focused attention (OR=2.19, 95% CI=1.03-4.65) and fine motor dexterity (OR=2.62, 95% CI=1.21-5.66) compared to survivors of supratentorial tumors. After adjusting for sex, age at diagnosis, shunt placement and cranial radiation (yes/no), infratentorial tumor location was only associated with reduced performance on a task of visual abstract reasoning (OR=3.76, 95% CI=1.40-10.1). Cranial radiation therapy was independently associated with impaired short-term memory (OR=15.6, 95% CI=1.64-147.8) and processing speed (OR=3.86, 95% CI=1.15-13.0). Conclusions: Tumor location was not associated with neurocognitive impairment after adjusting for treatment exposures. To further delineate potential differences associated with tumor location, future studies will examine factors including radiation dose/volume, extent of surgical resection, and medical complications.

AbstractRadiation therapy (RT) is a mainstay for the treatment of pediatric brain tumors. As improvements in and sophistication of this modality continue to increase the survival of patients, the long-term sequelae of RT pose significant challenges in the clinical management of this patient population as they transition into adulthood. In this special edition, we review the short- and long-term effects of RT for the treatment of pediatric brain tumors and the necessary surveillance required for follow-up.

Abstract INTRODUCTION Central nervous system germ cell tumor (GCT) is one of the pediatric brain tumors. Although there have been epidemiological studies in the past, long-term prognosis and the late effects remained unclear. In this study, we examined GCT over the past 41 years in Kumamoto prefecture. METHODS Epidemiological features and complications with radiation-induced tumors were searched in patients diagnosed with GCT in the 41-year period from 1977 to 2018. RESULTS There were 93 patients diagnosed with GCT. These cases were divided into 14-year periods before and after incorporation of chemotherapy into the treatment, and the results for germinomas were compared. An improvement in the 10-year survival rate from 12 of 23 cases (52.2%) between 1977 and 1991 to 19 of 28 cases (67.9%) between 1992 and 2006 was observed. The 10-year survival rate for germinoma cases that received medical treatment during a more recent 5-year period between 2004 and 2009 increased to over 90%. However, 10.3% of all long-term survivors of GCT developed radiation-induced glioblastoma. The examination results showed that regardless of the tumor type, patients who received a high dose of radiation during their initial treatment developed the complication of radiation-induced glioblastoma within 10 to 25 years after their initial treatment. CONCLUSION This study suggests that the long-term survival rates for GCT are improving but the rate of radiation-induced glioblastoma in these cases are too high to be ignored. Long-term follow-up of at least 10 years is essential to effectively evaluate the details of treatment for pediatric brain tumors.
