Background: Some pediatric patients with inflammatory demyelinating central nervous system disorders cannot be classified under any of the established disease entities, making their treatment and prognosis difficult. Objective: The objective of this study is to characterize a subgroup of pediatric patients with recurrent demyelinating central nervous system disorders. Methods: This study includes a case series of pediatric patients with monophasic or recurrent acute disseminated encephalomyelitis (ADEM) who later presented with either monophasic or recurrent optic neuritis (ON). Results: We describe seven patients with a median follow-up of six years (five females, two males) who presented at a median age of 6 years (range 4–8 years) with monophasic ( n = 4) or recurrent ADEM (two to four attacks) followed by monophasic ( n = 3) or recurrent ON (two to nine attacks). Cranial magnetic resonance imaging (MRI) was typical for ADEM ( n = 6) with complete or almost complete resolution of lesions on follow-up. Cerebrospinal (CSF) studies at the time of ADEM showed a pleocytosis in six patients and were negative for oligoclonal bands (OCBs) in all. In all patients high titers for serum anti-MOG antibodies were detected. Conclusion: ADEM followed by ON is a rare but distinct clinical phenotype among pediatric patients. Further studies are needed to allow recommendations on treatment or prognosis.

AbstractAcquired demyelinating syndromes (ADS) present with acute or subacute monofocal or polyfocal neurologic deficits localizing to the central nervous system. The clinical features of distinct ADS have been carefully characterized including optic neuritis, transverse myelitis, and acute disseminated encephalomyelitis. These disorders may all be monophasic disorders. Alternatively, optic neuritis, partial transverse myelitis, and acute disseminated encephalomyelitis may be first presentations of a relapsing or polyphasic neuroinflammatory disorder, such as multiple sclerosis or neuromyelitis optica. The clinical features of these disorders and the differential diagnosis are discussed in this article.

Abstract BACKGROUND Central nervous system (CNS) tumors are the most common solid neoplasms in the pediatric age, they comprise about a quarter of all cancers at this age. Little is known about the specific epidemiology of this group in Mexico and there are no reports of results focused on the Performance Status of patients who are treated in a multidisciplinary setting. OBJECTIVE To describe the Performance Status of CNS pediatric patients after being treated with a multidisciplinary approach in a tertiary center. METHODS We report a retrospective chart review of all pediatric patients who presented to the Neuro-Oncology Clinic at Teleton Pediatric Oncology Hospital in Queretaro, Mexico, from December 2014 to January 2020. We analyzed age, gender, the extent of surgical resection and histopathology. Performance Status was assessed using ECOG and Karnofsky/Lansky scores during every patient’s last follow-up visit. RESULTS A total of 56 patients were treated, epidemiology and histopathology variants are similar to those described in the international literature. With a median follow-up of 33 months, 35 patients are alive (62.5%), 28 of them (74.2%) have an excellent Performance Status (ECOG score 0 or Lansky/Karnofsky ≥ 90), 5 (14.2%) scored ECOG 1–2 and only 4 (11.4%) scored ECOG 3–4. CONCLUSIONS A multidisciplinary approach with a focus on Performance Status and the potential for neurological recovery is essential in the management of pediatric patients with CNS tumors. Efforts should be aimed at reducing post-surgical morbidity and early rehabilitation to reintegrate patients into society in the long term.

Positive Results

This study reports a case series of patients with upper limb neuromotor deficits following pediatric central nervous system tumor and treated with rehabilitative therapy according to action observation therapy (AOT). AOT is based on the “mirror neurons” system and had positive results in various non-oncologic neurologic pathologies. This study is the first experience in the oncology field, and included 6 patients, 4 of whom were fully evaluated at 6-month follow-up. In all patients, therapy showed improvement in all assessment tests. These promising results lead to further studies to confirm their effectiveness.

Background: Myelin oligodendrocyte glycoprotein (anti-MOG) antibody was reported in anti-aquaporin-4 (anti-AQP4) seronegative neuromyelitis optica spectrum disorders (NMOSD) patients. Objectives: To describe clinical phenotypes associated with anti-MOG. Methods: Seventy consecutive Thai patients with inflammatory idiopathic demyelinating central nervous system disorders (IIDCD) who were previously anti-AQP4 seronegative were tested for anti-MOG. Results: Anti-MOG was positive in six patients, representing 20.7% of the IIDCD anti-AQP4 seronegative patients with a non-multiple sclerosis phenotype, and most had relapses. All first presented with optic neuritis with good visual recovery after treatment. Conclusions: Anti-MOG positive patients may have manifestations that mimic NMOSD but differ in their course and prognosis from anti-AQP4 positive NMOSD.

Myelin oligodendrocyte glycoprotein is a protein exclusively expressed on the surface of oligodendrocytes and myelin in the central nervous system. Antibodies against myelin oligodendrocyte glycoprotein were initially detected in children with demyelinating syndromes, and more recently reported in a broad spectrum of central nervous system demyelinating diseases in adults, including neuromyelitis optica spectrum disorders and bilateral optic neuritis. Patients with myelin oligodendrocyte glycoprotein antibody-associated demyelination appear to have unique clinical and radiological features. To the best of our knowledge a series of Italian patients with optic neuritis and positivity to myelin oligodendrocyte glycoprotein antibodies has not yet been reported and the paper on myelin oligodendrocyte glycoprotein antibodies are more focused on clinical features, diagnosis and outcome than on the radiological appearance, so we want to retrospectively report magnetic resonance imaging features of a group of eight patients, who came to our Ophthalmologic Emergency Department for optic neuritis and were found seropositive for myelin oligodendrocyte glycoprotein antibodies, comparing our data with the findings described in the literature.

Abstract Second malignant neoplasms following treatment for primary central nervous system (CNS) tumors in children are rare occurrences but may often have dire consequences, particularly, if thought to be induced by prior therapies. The authors retrospectively reviewed pediatric patients with primary CNS malignancies from the University of Wisconsin over the last 25 years (1994 – 2019) with any secondary malignant neoplasm and determined seven patients met criteria. Treatment modalities were reviewed with all patients receiving surgery, chemotherapy, and radiotherapy for treatment of their first malignancy. The second neoplasms found included 4 high-grade gliomas, 1 meningioma, 1 thyroid carcinoma, and 1 myelodysplastic syndrome. The median latency time between diagnoses was 9 years (range 4 -17 years). The outcomes varied according to histopathology of the second neoplasm with the high-grade glioma patients all deceased from progressive disease. The high-grade gliomas were thought to have been induced by prior radiation in most cases. The remaining patients are still alive, at the time of this writing, and in follow up after treatment for their second neoplasm. Thus, long-term follow up is essential for children treated for a primary CNS tumor given the variety of second neoplasms that could arise with differential consequences. In addition to our single institutional outcomes, we will also present an updated review of the literature of pediatric patients with primary CNS tumors and second malignancies.

2002 Background: Neurotrophic tyrosine receptor kinase ( NTRK) gene fusions are oncogenic drivers in various tumor types, including central nervous system (CNS) tumors. Larotrectinib is a first-in-class, highly selective TRK inhibitor approved for the treatment of adult and pediatric patients with TRK fusion cancer, with an objective response rate (ORR) of 78% across 175 adult and pediatric patients with various non-CNS cancers (McDermott et al, ESMO 2020). We report data on patients with TRK fusion-positive primary CNS tumors. Methods: Patients with primary CNS tumors harboring an NTRK gene fusion enrolled in two clinical trials (NCT02637687, NCT02576431) were identified. Larotrectinib was administered until disease progression, withdrawal, or unacceptable toxicity. Response was investigator assessed. Results: As of July 2020, 33 patients with TRK fusion-positive CNS tumors were identified: 19 high-grade gliomas (HGG), 8 low-grade gliomas (LGG), 2 glioneuronal tumors, 2 neuroepithelial tumors, 1 CNS neuroblastoma, and 1 small round blue cell tumor. The patients had gene fusions involving NTRK2 (n = 24; 73%), NTRK1 (n = 5; 15%), and NTRK3 (n = 4; 12%). Median age was 8.9 years (range 1.3–79.0); 26 patients were pediatric ( < 18 years). Patients were heavily pre-treated with 45% having 2 or more prior lines of systemic therapy. The ORR in all patients was 30% (95% CI 16–49): 3 complete responses (all in pediatric patients), 7 partial responses (2 pending confirmation), 20 stable disease (including 15 pts > 6 months), and 3 progressive disease. The ORR in patients with HGG and LGG were 26% (95% CI 9–51) and 38% (95% CI 9–76), respectively. In all patients, the 24-week disease control rate was 73% (95% CI 54–87). Twenty-three of 28 patients (82%) with measurable disease had tumor shrinkage. The median time to response was 1.9 months. Median duration of response (DoR) was not reached (95% CI 3.8–not estimable [NE]) at a median follow-up of 12.0 months. The 12-month DoR rate was 75% (95% CI 45–100). Median PFS was 18.3 months (95% CI 6.7–NE) at a median follow-up of 16.5 months. Median overall survival (OS) was not reached (95% CI 16.9–NE) at a median follow-up of 16.5 months, with a 12-month OS rate of 85% (95% CI 71–99). Duration of treatment ranged from 1.2 to 31.3+ months. Treatment-related adverse events (TRAE) were reported by 20 patients and were Grade 3–4 in 3 patients (9%). There were no treatment discontinuations due to TRAEs. Conclusions: In patients with TRK fusion-positive CNS tumors, larotrectinib demonstrated rapid and durable responses, high disease control rate, and a favorable safety profile. These results support testing for NTRK gene fusions in patients of all ages with CNS tumors. Clinical trial information: NCT02637687, NCT02576431.
