Abstract BACKGROUND Nearly 80,000 new cases of primary brain tumors are expected to be diagnosed this year in the United States: 32% of CNS tumors are malignant. Anecdotally, patients who report use of cannabis, frequently describe higher quality of life scores (QOL) in standardized instruments. However, the lack of available tools that allow systematic documentation of cannabis use results in a barrier to accurately assess efficacy and potential benefits and risks. MATERIAL AND METHODS We conducted a single center, observational study: patients with primary brain tumors answered a previously validated instrument to explore cannabis use. QOL was assessed using the instruments from the European Organisation for Research and Treatment of Cancer(EORTC): QLQ-C30 and its complementary module BN-20 as well as the EuroQol group’s instrument EQ-5D-5L. Eligible participants were identified as cannabis users or non-users, completing the instruments in a self-administered fashion. RESULTS To date, 45 patients who signed informed consent were enrolled and answered the questionnaires, mean age was 51 (SD 13.5) years, 31 were male, 25 were considered active cannabis users (624% males and 36% females). At baseline, the mean Global Health score in the QLQ-C30 instrument was 68.6 (SD: 20.6) among cannabis users and 82 (SD: 18.05) among non-users. The mean difference in Global Health QOL scores between users and non-users was 13.35 (95%CI: 1.34, 25.35; p=0.03). In contrast the difference between cannabis users and non-users in QOL index in the EQ-5D-5L instrument was 0.13 (0.77 vs 0.91; p=0.002). Among cannabis users, patients perceive their symptoms as moderate before using cannabis and mild after using cannabis (p>0.001). CONCLUSION In our analysis, patients who use cannabis have, on average, lower QOL scores signaling that sicker patients resort to cannabis to improve their symptoms and ultimately their quality of life. Patients’ perception is one of improvement in the overall quality of life when using cannabis. Our findings provide background support to perform prospective studies in the impact of cannabis in quality of life of patients with central nervous system tumors.

Introduction: Tumors of the central nervous system (CNS) are primary or secondary neoplasms located within the craniovertebral cavity. The incidence of CNS tumors is not uniform with variation between different countries, age groups and races. Objective: Our study aim was to generate new knowledge of the epidemiology of central nervous system tumors in Rwanda. Method: This was an observational retrospective study of all patients diagnosed with CNS tumors in Rwanda over a period of 10 years, from 1st January 2006 to 31st December 2015. Results: 466 patients enrolled, (52.2% females, 47.8% males). The median age at diagnosis of was 37 years. Brain tumors were 82.7%; spine tumor patients were 16.4%. The average annual age-standardized incidence of CNS tumors was 0.43/100, 0000 person-years and varied with age groups. Tumors of meningothelial cells represented the majority of brain tumors (31.8%). Metastatic tumors were the far most common spine tumors category. 55.8 % of CNS tumors reported in our study were histologically confirmed and of nonmalignant meningiomas were the commonest (33.9%). Conclusion: This is the very first study done on epidemiology of CNS tumors in Rwanda, and generated data about incidence of CNS tumors in Rwanda and their location and histological distribution.

Low-grade tumors of the central nervous system constitute 15 to 35% of primary brain tumors. Although this category of tumors encompasses a number of different well-characterized entities, low-grade tumors constitute every tumor not obviously malignant at initial diagnosis. In this brief review, the authors discuss the pathological classification, diagnostic procedures, treatment, and possible pathogenic mechanisms of these tumors. Emphasis is given in the neu-roradiological and pathological features of the several entities.

Central nervous system tumors are extremely rare in the pediatric population and molecularly heterogeneous. Growing scientific research and clinical practice experience are improving medical therapies to increase survival outcomes and quality of life and reduce side effects. The 2019 Neurobiology of Disease in Children Symposium, held in conjunction with the 48th annual meeting of the Child Neurology Society, aimed to (1) describe molecular advances in tumor classification, (2) better understand the evolution of targeted therapies, and (3) more clearly formulate a treatment plan for patients. The article summarizes the presentations and includes an edited transcript of a panel discussion.

Alterations of the v-raf murine sarcoma viral oncogene homolog B (BRAF) have been extensively studied in several tumor entities and are known to drive cell growth in several tumor entities. Effective targeted therapies with mutation-specific small molecule inhibitors have been developed and established for metastasized malignant melanoma. The BRAF V600E mutation and KIAA1549-BRAF fusion are alterations found in several brain tumors and show a distinct prognostic impact in some entities. Besides the diagnostic significance for the classification of central nervous system tumors, these alterations present possible therapy targets that may be exploitable for oncological treatments, as it has been established for malignant melanomas. In this review the different central nervous system tumors harboring BRAF alterations are presented and the diagnostic significance, prognostic role, and therapeutic potential are discussed.
