Abstract
Cutaneous neurofibromas (cNF) contribute to the impairment of QOL in individuals with neurofibromatosis 1. The cNF-Skindex, validated in a French population, specifically assesses the cNF-related QOL. In this study, we first defined severity strata using an anchoring approach on the basis of patient's burden. In total, 209 patients answered the anchor question and the cNF-Skindex. We tested the agreement among the three strata, generated by all potential couples of cut-off values of the cNF-Skindex and the three strata defined in the anchor question. The cut-off values 12 and 49 provided the highest Kappa value (κ = 0.685, 95% confidence interval = 0.604-0.765). Second, we validated the score and the strata in a United States population using the answers provided by 220 French and 148 United States adults. In the multivariable linear regression analysis, the country of origin was not a factor associated with the score (P = 0.297). The number of cNF along the different severity strata was similar between the French and the United States populations. In conclusion, stratification constitutes a powerful tool to better interpret the cNF-Skindex in daily practice and in clinical trials. This study validates its use in two populations that together constitute a large cohort of patients willing to participate in clinical research.

Abstract
BACKGROUND People with NF1 have an increased prevalence of central nervous system malignancy. However, little is known about the clinical course or pathologic features of NF1-associated gliomas in adults, limiting clinical care and research. METHODS Adults (≥18 years) with NF1 and histologically confirmed non-optic pathway gliomas (non-OPGs) at Johns Hopkins Hospital, Memorial Sloan Kettering Cancer Center, and Washington University presenting between 1990 and 2020 were identified. Retrospective data were collated, and pathology was reviewed centrally. RESULTS Forty-five patients, comprising 23 females (51%), met eligibility criteria, with a median of age 37 (18-68 years) and performance status of 80% (30%-100%). Tissue was available for 35 patients. Diagnoses included infiltrating (low-grade) astrocytoma (9), glioblastoma (7), high-grade astrocytoma with piloid features (4), pilocytic astrocytoma (4), high-grade astrocytoma (3), WHO diagnosis not reached (4) and one each of gliosarcoma, ganglioglioma, embryonal tumor, and diffuse midline glioma. Seventy-one percent of tumors were midline and underwent biopsy only. All 27 tumors evaluated were IDH1-wild-type, independent of histology. In the 10 cases with molecular testing, the most common genetic variants were NF1, EGFR, ATRX, CDKN2A/B, TP53, TERT, and MSH2/3 mutation. While the treatments provided varied, the median overall survival was 24 months [2-267 months] across all ages, and 38.5 [18-109] months in individuals with grade 1-2 gliomas. CONCLUSIONS Non-OPGs in adults with NF1, including low-grade tumors, often have an aggressive clinical course, indicating a need to better understand the pathobiology of these NF1-associated gliomas.

Abstract
Cutaneous neurofibromas (cNFs) are the most common tumor in people with the rasopathy neurofibromatosis type 1. They number in hundreds or even thousands throughout the body, and currently, there are no effective interventions to prevent or treat these skin tumors. To facilitate the identification of novel and effective therapies, essential studies including a more refined understanding of cNF biology and the role of RAS signaling and downstream effector pathways responsible for cNF initiation, growth, and maintenance are needed. This review highlights the current state of knowledge of RAS signaling in cNF pathogenesis and therapeutic development for cNF treatment.

Abstract
Neurofibromatosis type 1 (NF1) is caused by a nonfunctional copy of the NF1 tumor suppressor gene that predisposes patients to the development of cutaneous neurofibromas (cNFs), the skin tumor that is the hallmark of this condition. Innumerable benign cNFs, each appearing by an independent somatic inactivation of the remaining functional NF1 allele, form in nearly all patients with NF1. One of the limitations in developing a treatment for cNFs is an incomplete understanding of the underlying pathophysiology and limitations in experimental modeling. Recent advances in preclinical in vitro and in vivo modeling have substantially enhanced our understanding of cNF biology and created unprecedented opportunities for therapeutic discovery. We discuss the current state of cNF preclinical in vitro and in vivo model systems, including two- and three-dimensional cell cultures, organoids, genetically engineered mice, patient-derived xenografts, and porcine models. We highlight the models' relationship to human cNFs and how they can be used to gain insight into cNF development and therapeutic discovery.

Abstract
A consistent set of measurement techniques must be applied to reliably and reproducibly evaluate the efficacy of treatments for cutaneous neurofibromas (cNFs) in people with neurofibromatosis type 1 (NF1). cNFs are neurocutaneous tumors that are the most common tumor in people with NF1 and represent an area of unmet clinical need. This review presents the available data regarding approaches in use or development to identify, measure, and track cNFs, including calipers, digital imaging, and high-frequency ultrasound sonography. We also describe emerging technologies such as spatial frequency domain imaging and the application of imaging modalities such as optical coherence tomography that may enable the detection of early cNFs and prevention of tumor-associated morbidity.

Abstract
PURPOSE To compare the qualitative and quantitative features of peripheral lesions on localized (L) and whole-body (WB) magnetic resonance imaging (MRI) in people with neurofibromatosis type 1 (NF1) and schwannomatosis. MATERIALS AND METHODS This is a retrospective, HIPAA compliant study with twenty-seven patients (14 women, 13 men; mean age (years): 38 (3-67)) who underwent both L-MRI and WB-MRI without interval treatment. WB-MRI and L-MRI were comprised of T1-weighted, fat suppressed (FS) T2-weighted or short tau inversion recovery (STIR), diffusion-weighted imaging (DWI) using b-values of 50, 400, and 800 s/mm2, apparent diffusion coefficient (ADC) mapping and pre- and post-contrast FST1 sequences. Two readers recorded qualitative (T1 and T2/STIR signal intensity and heterogeneity, contrast enhancement and heterogeneity, perilesional enhancement, presence of a target sign and perilesional edema) and quantitative (size, signal-to-noise ratio (SNR), contrast-to-noise ratio (CNR), ADC) features of peripheral lesions on L-MRI and WB-MRI.Descriptive statistics, Wilcoxon signed-rank test and McNemar's test were used. RESULTS There were 31 peripheral lesions identified in 27 subjects, (mean size: 3.1 cm (range: 1-8.1 cm) on both L-MRI and WB-MRI).There were no differences in T1 signal and heterogeneity and T2/STIR signal and heterogeneity between WB-MRI and L-MRI ((p = 0.180, 0.083, 0.317 and 0.157 respectively). There were also no differences in contrast enhancement, heterogeneity and perilesional enhancement between WB-MRI and L-MRI (p = 1.000, 0.380 and 1.000 respectively). Presence of a target sign and perilesional edema did not differ between WB-MRI and L-MRI (p = 1.000 and 0.500 respectively). Craniocaudal (CC), mediolateral (ML) and anteroposterior (AP) size measurements on WB-MRI did not differ from CC, ML and AP size measurements on L-MRI (p = 0.597, 0.128 and 0.783 respectively). SNR on WB-DWI did not differ from SNR on L-DWI for b50, b400 and b800 images (p = 0.285, 0.166, and 0.974 respectively), and CNR on WB-DWI did not differ from CNR on L-DWI for b50, b400 and b800 images (p = 0.600, 0.124, and 0.787 respectively). There was no significant difference in minimum, mean and maximum ADC values between WB-DWI and L-DWI (p = 0.234, 0.481, and 0.441 respectively). Median minimum, mean and maximum ADC (×10(-3)mm(2)/s) differences between WB-DWI and L-DWI were 0.0 (range -1 to 0.7), 0.0 (range -0.5 to 0.6), and 0.1 (range -1.2 to 0.8) respectively. Relative ADC difference averages were 29.1% for minimum values, 10.1% for mean values, and 14.8% for maximum values. CONCLUSION WB-MRI yields qualitative and quantitative features for peripheral lesions, including DWI and ADC measurements, that are comparable to L-MRI scans. WB-DWI can be reliably used for the assessment of peripheral nerve sheath tumors, obviating the need for a repeat follow-up L-DWI acquisition.

Abstract
The global transcription inhibitor terameprocol is being evaluated clinically as an oral formulation to treat high-grade glioma. A sensitive, reliable method was developed to quantitate terameprocol using LC-MS/MS to perform detailed pharmacokinetic studies. Sample preparation involved protein precipitation using acetonitrile. Separation of terameprocol and the internal standard, Sorafenib-methyl-d3, was achieved with a Zorbax XDB C18 column (2.1 × 50 mm, 3.5 µm) and gradient elution over a 2-minute total analytical run time. A SCIEX 4500 or SCIEX 5500 triple quadrupole mass spectrometer operated in positive electrospray ionization mode was used for terameprocol detection. The assay range of 5-1000 ng/mL was demonstrated to be accurate (92.7-107.4%) and precise (CV ≤ 11.3%). A sample diluted 1:10 (v/v) was accurately quantitated. Terameprocol in plasma has been proven stable for at least 20 months when stored at -70 °C. The method was applied to the measurement of total plasma concentrations of terameprocol in a patient with a high-grade glioma receiving a 300 mg oral dose.

Abstract
OBJECTIVE There has been limited research on the efficacy of multidisciplinary tumor boards (MDTBs) in improving the treatment of patients with tumors affecting the nervous system. The objective of the present study was to quantify the utility of MDTBs in providing alternative diagnostic interpretations and treatment plans for this patient population. METHODS The authors performed a prospective study of patients in 4 hospitals whose cases were discussed at MDTBs between July and November 2019. Patient demographic data, diagnoses, treatment plans, and eligibility for clinical trials were recorded, among other variables. RESULTS A total of 176 cases met eligibility criteria for study inclusion. The majority (53%) of patients were male, and the mean patient age was 52 years. The most frequent diagnosis was glioblastoma (32.4%). Among the evaluable cases, MDTBs led to 38 (21.6%) changes in image interpretation and 103 (58.2%) changes in patient management. Additionally, patients whose cases were discussed at MDTBs had significantly shorter referral times than patients whose cases were not discussed (p = 0.024). CONCLUSIONS MDTB discussions led to significant numbers of diagnostic and treatment plan changes as well as shortened referral times, highlighting the potential clinical impact of multidisciplinary care for patients with nervous system tumors.

Abstract
Access to healthcare in Mexico is available to its population via publicly and privately funded institutions. The public sector, administered by both the local and federal government under the jurisdiction of the Department of Health, provides healthcare to the majority of the country's population. Privately funded institutions vary in size and scope of practice, ranging from small clinics focused on family practice, to large tertiary hospitals with capacity for treating patients with complex conditions and performing clinical research. The evaluation and treatment of patients with cancer in Mexico is also available through both sectors. In the country's capital, Mexico City, patients with glioblastoma are primarily treated at the National Institute of Neurology and Neurosurgery and the National Institute of Oncology. Epidemiological data is incomplete due to the lack of a national cancer registry. In the case of neoplasms of the central nervous system, the available information suggests that gliomas represent 33% of all intracranial tumors. The treatment of patients in Mexico diagnosed with glioblastoma has not been standardized owing to the lack of resources in some communities and the expense of antineoplastic agents. Current options range from a biopsy only to maximal safe resection followed by adjuvant treatment with radiation and chemotherapy. Currently, basic science and clinical research is being conducted in academic institutions associated with universities and in private hospitals. Studies include the evaluation of tumor biology, neuroimaging biomarkers and new treatment options such as the use of chloroquine.

Abstract
2568 Background: Wee1 is a key regulator of the G2/M checkpoint and is frequently overexpressed in glioblastoma (GB). Adavosertib is a first-in-class oral, small molecule inhibitor of Wee1 that acts primarily as a DNA damage sensitizer. A phase I clinical trial was conducted to evaluate its safety and establish the recommended phase II dosing. Studies were undertaken to evaluate whether potentially therapeutic concentrations of the drug are achieved in recurrent tumor and adjacent non-enhancing brain regions with presumed intact blood-brain barrier (BBB). Methods: Twelve patients received five daily doses of adavosertib pre-operatively at either the maximum tolerated dose (MTD) for concurrent radiation or adjuvant temozolomide. Tissue from contrast enhancing (CE) and non-enhancing (NE) brain regions was obtained for analysis during surgical resection. A second stage is being conducted using microdialysis (MD) to facilitate continuous sampling of extracellular fluid (ECF) and measuring free drug concentrations in: normal-appearing brain, contrast enhancing tumor, and a peritumoral T2 hyperintense area. The concentration of total adavosertib in plasma and tissue homogenates and free drug in ECF were determined by validated LC/MS/MS methods. Results: Geometric mean concentrations of adavosertib after a 200 mg dose were 644 ng/mL and 119 ng/mL in CE and NE tissue specimens, respectively (6 patients). At the 425 mg dose, the mean concentrations were 3,576 ng/mL in CE tissue and 885 ng/mL in NE tissue (6 patients). MD was performed in 2 patients. Samples from functional MD catheters were collected from NE brain in patient no. 1 and from two NE areas and a FLAIR hyperintense region in patient no. 2, with the following results in the table. Conclusions: The total drug concentration in tissue samples was notably lower in regions of the brain with a relatively intact BBB as compared to contrast enhancing tissue. Concentrations of adavosertib measured by MD vary markedly depending on catheter location. Free drug levels in ECF within brain with a functional BBB, although considerably lower than total drug levels in tissue, were 2-10 times below the previously reported IC50 for antiproliferative activity against sensitive GB cell lines (127 ng/mL). Whether or not the target of the drug is effectively inhibited at these concentrations remains to be demonstrated. Clinical trial information: NCT01849146 . [Table: see text]

Abstract
Histone mutations occur in approximately 4% of different cancer types. In 2012, mutations were found in the gene encoding histone variant H3.3 (H3F3A gene) in pediatric diffuse intrinsic pontine gliomas and pediatric hemispheric gliomas. Tumors with mutations in the H3F3A gene are generally characterized as histone mutated gliomas (HMGs) or diffuse midline gliomas. HMGs are a rare subtype of glial tumor that is malignant and fast growing, carrying a poor prognosis. In 2017, the Beau Biden Cancer Moonshot Program appropriated $1.7 billion toward cancer care in 10 select areas. The National Cancer Institute (NCI) was granted support to focus specifically on rare central nervous system (CNS) tumors through NCI-CONNECT. Its mission is to address the challenges and unmet needs in CNS cancer research and treatment by connecting patients, providers, researchers, and advocacy organizations to work in partnership. On September 27, 2018, NCI-CONNECT convened a workshop on histone mutated midline glioma, one of the 12 CNS cancers included in its initial portfolio. Three leaders in the field provided an overview of advances in histone mutated midline glioma research. These experts shared observations and experiences related to common scientific and clinical challenges in studying these tumors. Although the clinical focus of this workshop was on adult patients, one important objective was to start a collaborative dialogue between pediatric and adult clinicians and researchers. Meeting participants identified needs for diagnostic and treatment standards, disease biology and biological targets for this cancer, disease-specific trial designs, and developed a list of action items and future direction.

Abstract
BACKGROUND Medulloblastoma (MB) is a rare brain tumor occurring more frequently in children in whom research has been primarily focused. Treatment recommendations in adults are mainly based on retrospective data and pediatric experience; however, molecular features and treatment tolerance differ between the 2 age groups. In adults, prognostic tools are suboptimal, late recurrences are typical, and long-term sequelae remain understudied. Treatment has not adapted to molecular classification advances; thus, the survival rate of adult MB has not improved. METHODS In 2017, the National Cancer Institute (NCI) received support from the Cancer Moonshot℠ to address the challenges and unmet needs of adults with rare central nervous system tumors through NCI-CONNECT, a program that creates partnerships among patients, health care professionals, researchers, and advocacy organizations. On November 25, 2019, NCI-CONNECT convened leading clinicians and scientists in a workshop to review advances in research, share scientific insights, and discuss clinical challenges in adult MB. RESULTS Working groups identified unmet needs in clinical trial design, tissue acquisition and testing, tumor modeling, and measurement of clinical outcomes. CONCLUSIONS Participants identified opportunities for collaboration; discussed plans to create a working group of clinicians, researchers, and patient advocates; and developed specific action items to expedite progress in adult MB.

Abstract
PURPOSE OF REVIEW As the treatment of many malignancies has improved, brain metastases (BM) have been observed as a site of the first recurrence in patients with controlled systemic cancers. This suggests that while the administered chemotherapy is effective against systemic cancer, drug concentrations in the central nervous system (CNS) are likely too low to be effective. These findings are in accord with data suggesting that more than 98% of FDA-approved drugs on the market today are unable to cross the blood-brain barrier (BBB). RECENT FINDINGS This retrospective literature review was conducted to estimate the proportion of patients with non-small lung cancer, breast cancer, and melanoma who develop BM as their initial site of recurrence while their systemic cancers are well controlled. Of 267 studies screened, 12 studies fit criteria for inclusion. These 12 studies reported on 923 patients. According to compiled data across these studies, 16% of patients on chemotherapy with stable or responding systemic cancer developed isolated BM as their initial site of relapse. These findings strongly suggest that while chemotherapy controlled systemic cancer, drug concentrations within the CNS were low enough to allow disease progression. Ultimately, reducing the incidence of BM in these patients will require novel therapeutic approaches that facilitate drug entry through an intact BBB early in their treatment.

Abstract
e13590 Background: As the treatment of non-central nervous system (CNS) malignancies improves, brain metastases (BM) are occurring more often in patients with controlled primary disease. In a retrospective analysis of 1953 patients with BM, 44.7% had a controlled primary tumor at the time of BM diagnosis. Given that prognosis after BM remains dismal, it is necessary to identify groups who might benefit from improved delivery of initial systemic therapy across the blood brain barrier (BBB). Methods: A retrospective literature review was conducted to estimate the proportion of patients with non-small cell lung cancer (NSCLC), breast cancer, and melanoma treated with chemotherapy in whom BM was the initial site of recurrence. Only studies explicitly reporting CNS metastasis with controlled extra-cranial (EC) disease on chemotherapy or reporting the first site of recurrence after chemotherapy were included. Results: Four studies of advanced NSCLC reported an average of 23% of patients who developed BM as an initial site of recurrence. Breast cancer cases varied by subtype with a range of 4 - 19%. In four papers reporting HER-2 status, an average of 14% of patients treated with traztuzumab had CNS metastasis with controlled EC disease. In three papers assessing patients with metastatic melanoma on chemotherapy, 4 – 25% initially progressed in the CNS. Conclusions: Of the 1024 patients treated with chemotherapy and achieving controlled systemic disease in this retrospective review, first recurrence in the brain was common: 23% in NSCLC, 12% in breast cancer, and 12% in melanoma. While chemotherapy controlled non-CNS disease, concentrations of these drugs were clearly subtherapeutic in the CNS. Preventing BM in patients with NSCLC, breast cancer, and melanoma will require novel therapeutic approaches designed to facilitate drug entry through an intact BBB early in the treatment of the primary tumor.

Abstract
e13562 Background: Neurofibromatosis type 1 (NF1) is caused by mutations of the tumor suppressor gene NF1 resulting in decreased levels of neurofibromin and dysregulation of the RAS pathway, including MEK/ERK upregulation. NF1 is characterized by multiple benign and malignant tumors. Central nervous system tumors have an overall standardized incidence ratio of 37.5 in population studies with high rates of aggressive gliomas in adults with NF1. The response to standard glioma therapies is mixed. MEK1/2 inhibitors have shown activity in NF1 driven plexiform neurofibromas and low grade gliomas, however, data is lacking about the optimal dose or sequencing of MEK1/2 inhibitors for adults with NF1 associated aggressive gliomas. We present recent experiences with the MEK1/2 inhibitor trametinib in adults with NF1 and aggressive gliomas. Methods: A retrospective chart review was conducted on all adult patients with NF1 and astrocytoma treated with trametinib at the Johns Hopkins Brain Cancer Program between 2016-2018. Results: Three patients met selection criteria. Two received trametinib as initial therapy (2 mg daily). All developed an acneiform rash; one had transient transaminitis requiring temporary discontinuation and subsequent dose reductions. Clinical benefit was achieved associated with two partial radiographic responses. Conclusions: Astrocytomas in adults with NF1 often have a more aggressive course than suggested by histology. The cases presented here demonstrate clinical benefit from single agent MEK inhibition as well as possible synergistic effects with conventional therapies for gliomas in this patient population. These observations highlight the need for further research in this area. [Table: see text]

Abstract
e13530 Background: Standard therapy for patients with newly diagnosed glioblastoma (GBM) includes concurrent temozolomide (TMZ) and radiation (RT) followed by six monthly cycles of adjuvant TMZ. Although TMZ improves survival for MGMT methylated patients, it is unclear if this benefit is from the TMZ given with the radiation, the adjuvant TMZ, or if both are required. This retrospective study was designed to identify MGMT methylated patients who started treatment with near-normal functional status, completed concurrent RT+TMZ, but did not receive adjuvant TMZ to estimate if their survival was significantly less than expected. Methods: We reviewed charts from 190 adults diagnosed with GBM at Johns Hopkins Hospital from 2013 to 2015 recording their Karnofsky Performance Score (KPS), extent of resection, MGMT-methylation and IDH1 mutation status, and treatment records. We selected patients with MGMT-methylated GBM who received concurrent RT+TMZ without adjuvant TMZ for this study. Patients with a KPS < 70 or severe post-radiation complications were excluded. Results: Six patients met the selection criteria. They had a median age of 65 years, average KPS of 80, 2/6 had a gross total resection, and all were IDH1 wildtype. Their overall survival ranged from 17 to > 46 months. Conclusions: The overall survival of these patients who received no adjuvant TMZ is very similar to the median of 23 months reported in the literature for MGMT methylated patients who received adjuvant TMZ. This preliminary data suggests that a prospective study in MGMT methylated patients comparing concurrent RT+TMZ followed by either standard adjuvant TMZ or observation could be considered without placing patients in the experimental arm at excessive risk.[Table: see text]

Abstract
Background Gliomas with 1p/19q-codeletion as well as mutation of isocitrate dehydrogenase (IDH) 1 are typically characterized as oligodendrogliomas with comparatively good response to treatment with radiation and chemotherapy. Case presentation We present the case of a 28-year-old man with an IDH1 and TP53 mutant high grade glioma with abnormalities in chromosomes 1 and 19 suggestive of anaplastic oligodendroglioma that rapidly progressed to widespread metastatic disease. Biopsy of a liver lesion confirmed metastasis of the patient’s known brain primary and chemotherapy with temozolomide was initiated. The patient’s rapidly growing tumor burden with fulminant liver failure and tumor lysis led to multisystem failure of which the patient died. Further molecular testing illustrated features more consistent with glioblastoma: multiple large chromosomal aberrations including loss of whole chromosome 1 and 2q; gain/amplification of MYCN, MET, and CDK4; loss of CDKN2A/B; and an ATRX mutation. Conclusion This case illustrates the importance of higher level molecular diagnostic testing for patients with particularly aggressive disease progression that is not concordant with standard prognoses. Additional data on cases with atypical alterations of 1p and 19q are needed to better understand the distinct biology of these cancers so that appropriate therapies can be developed.
