Abstract BACKGROUND Cannabinoids, including cannabidiol (CBD) and tetrahydrocannabinol (THC), are a class of compounds found in marijuana. Numerous studies in adults have examined cannabinoid use in management of cancer-related symptoms such as nausea, anorexia, and pain. Less is known about the use in the pediatric oncology population. METHODS A prospective observational study has been ongoing since 2016 at Children’s Hospital Colorado to evaluate cannabinoids’ impact using PedsQL™ modules on quality of life of pediatric patients with central nervous system (CNS) tumors who are 2–18 years old. Laboratory assessments of T-cell activity and pharmacokinetics of CBD, THC and associated metabolites are in process. Diaries with exploratory information on cannabinoid use patterns are being collected. RESULTS Thirty-three patients (14:19; male:female) have been enrolled with a median age of 6.4 years (range, 2.9–17.7 years). The most common tumor type in enrolled patients is embryonal tumors (13/33; 39%). Nine (27%) patients have low-grade glial/glioneuronal tumors, and eight (24%) had high-grade/diffuse midline gliomas. The remaining patients had ependymoma or craniopharyngioma. The median time on cannabinoids is 9 months. Most (n=20) patients have used oral products with CBD and THC. One patient continues on cannabinoid therapy in follow up. Preliminary immune function analyses identified impaired neutrophil superoxide anion production and chemotaxis in patients taking cannabinoids at early time points on therapy. CONCLUSIONS Families of children with various CNS tumors are pursuing cannabinoid therapy for both antitumor and supportive care purposes. Analysis of the impact of cannabinoids on patients’ quality of life is ongoing.

Abstract Cerebellar liponeurocytoma consists of well-differentiated neurons with the cytology of neurocytes in addition to a population of lipidized cells. Hence it is biphasic in appearance and has been included in the category of glioneuronal tumors of the central nervous system by the WHO working group on the Classification of Tumors of the Nervous System. However, liponeurocytoma is not exclusive to the cerebellar or fourth ventricular location. Since its inclusion in the central nervous system tumor classification, nine cases with similar histological and immunohistochemical features have also been described in the lateral ventricles. We describe here such a lateral ventricular tumour in a 30-year-old woman, characteristically showing divergent glio-neuronal differentiation and lipidized neoplastic cells. Therefore, we suggest that future WHO tumor classification should consider that liponeurocytomas are not entirely restricted to the cerebellum and henceforth change of nomenclature might be considered, as also pointed out by other authors.

Abstract Prior reports suggest the low prevalence of primary central nervous system (PCNS) tumors and the healthcare setting where patients seek care can contribute to diagnostic delays, potentially affecting prognosis. This descriptive report highlights findings from patient-reported data at presentation collected from a sample of 623 PCNS tumor patients. Participants were White (88%), males (56%), median age at diagnosis 41 (2-79) with high grade (HG) (66%) brain tumors (BT) (89%). Among BT patients, 30% reported ≥ 3 concurrent symptoms at presentation including headaches (40%), seizures (30%), and memory problems or difficulty with balance/walking (20% each). Over half (57%) had symptoms for < 6 months before diagnosis and 60% presented to the Emergency Room. Sixty-five percent of HG BT patients had symptoms for < 6 months prior to diagnosis compared to low grade (LG) tumors (40%) and had surgery in < 1 month from presentation (68% vs 51%, p < 0.01). More HG BT patients presented with weakness in the arms/legs than LG BT (14% vs 8%). Among spine tumor (ST) patients, 45% reported ≥ 3 concurrent symptoms at presentation including back pain (65%), sensory changes (45%), and weakness (40%). Almost half (46%) were symptomatic for > 1 year before diagnosis, presented in an outpatient clinic (64%) with 41% having surgery < 1 month from presentation. Younger (40% vs 16%) and HG ST patients (56% vs 21%) more often reported symptoms for < 6 months before diagnosis. HG ST patients more often presented to Emergency Rooms (67% vs 25%) and had surgery < 1 month from presentation (60% vs 36%). Further analysis of symptom presentation and clinical course is ongoing. Tumor location, grade, patient age and healthcare setting were associated with the time from clinical presentation to diagnosis. Development of aids providing guidance on diagnostic evaluation/treatment to front-line healthcare providers is warranted.

Introduction: CNS tumor requires intraoperative decision making regarding the extent of tumor removal. Clinical examination and imaging studies are not sufficient enough to predict the biological behavior of the tumors. Squash cytology is a quick method of evaluation of cytomorphologic features prepared from smear technique and provide the preliminary diagnosis and aid in intraoperative decision making by differentiating neoplastic from non neoplastic and benign from malignant lesions. The aim of this study is compare the diagnostic accuracy of squash cytology to that of histopathological examination. Methods: This study consists of 36 specimens from both brain and spine subjected to both squash cytology and histopathological evaluation. The squash preparation and histopathological finding were later compared and diagnostic accuracy calculated. Results: Gliomas are the most common tumor encountered and the accuracy of Squash cytology obtained was 71%. In meningioma, 100% diagnostic accuracy was obtained however, there was limitation in accurately predict the subgroup of tumor by squash cytology alone. Other neoplastic lesions included in this study were Schwannoma, Oligodendroglioma, Ependymoma, mixed tumors and others. Overall, the accuracy predicted by squash cytology is found to be 77.8 % in this study. Conclusion: Squash cytology is rapid and reliable method of tissue diagnosis that aid in intraoperative decision making regarding the extent of Central Nervous System tumor excision
