Leptomeningeal carcinomatosis (LMC) is a fatal but uncommon complication occurring in 5–15% of patients with stage IV cancer. Current treatment options are ineffective at managing leptomeningeal spread, with a median overall survival (mOS) of 2–6 months. We aimed to conduct a systematic review of the literature to identify past and future therapies for LMC from solid tumors. Forty-three clinical trials (CTs) published between 1982–2022 were identified. Of these, 35 (81.4%) were non-randomized CTs and 8 (18.6%) were randomized CTs. The majority consisted of phase I (16.3%) and phase II CTs (65.1%). Trials enrolled patients with LMC from various primary histology (n = 23, 57.5%), with one CT evaluating LCM from melanoma (2.4%). A total of 21 trials evaluated a single modality treatment. Among CTs, 23.7% closed due to low accrual. Intraventricular (ITV)/intrathecal (IT) drug delivery was the most common route of administration (n = 22, 51.2%) vs. systemic drug delivery (n = 13, 30.3%). Two clinical trials evaluated the use of craniospinal irradiation for LMC with favorable results. LMC continues to carry a dismal prognosis, and over the years, increments in survival have remained stagnant. A paradigm shift towards targeted systemic therapy with continued standardization of efficacy endpoints will help to shed light on promising treatments.

: Background: Barriers to care cause delays in seeking, reaching, and getting care. These delays affect low-and middle-income countries (LMICs), where 9 out of 10 LMIC inhabitants have no access to basic surgical care. Knowledge of healthcare utilization behavior within underserved communities is useful when developing and implementing health policies. Little is known about the neurosurgical health-seeking behavior of African adults. This study evaluates public awareness, knowledge of availability, and readiness for neurosurgical care services amongst African adults. Methodology: The cross-sectional study will be run using a self-administered e-survey hosted on Google Forms (Google, CA, USA) disseminated from 10th May 2021 to 10th June 2021. The Questionnaire would be in two languages, English and French. The survey will contain closed-ended, open-ended, and Likert Scale questions. The structured questionnaire will have four sections with 42 questions; Sociodemographic characteristics, Definition of neurosurgery care, Knowledge of neurosurgical diseases, practice and availability, and Common beliefs about neurosurgical care. All consenting adult Africans will be eligible. A minimum sample size of 424 will be used. Data will be analyzed using SPSS version 26 (IBM, WA, USA). Odds ratios and their 95% confidence intervals, Chi-Square test, and ANOVA will be used to test for associations between independent and dependent variables. A P-value <0.05 will be considered statistically significant. Also, a multinomial regression model will be used. Dissemination: The study findings will be published in an academic peer-reviewed journal, and the abstract will be presented at an international conference. Highlights:

: Background: A significant proportion of the public rely on the internet for their health information, and social media has emerged as the principal information source. YouTube is the world’s largest and most popular video library, and it has emerged as a primary health information source because it offers animated and interactive content. However, little is known of its usefulness of neurosurgery videos to African YouTube users. We aim with this study to evaluate the usefulness of YouTube as a source of patient information for neurosurgical care in Africa. Methodology: This observational study will be conducted using YouTube. A search will be carried out to identify neurosurgery videos suggested to African YouTube viewers from inception to September 2021. An internet browser (Google Chrome, Google Inc., CA, USA) with its cache cleared will be used to execute the search. The default YouTube search setting of “relevance” will be used to replicate what a search attempt performed by a patient would be. The first 50 results from each keyword search will be registered in a Microsoft Excel spreadsheet (Microsoft, WA, USA). The primary outcome measure is the reliability of the videos. Data will be analyzed using SPSS version 26 (IBM, WA, USA). Odds ratios and their 95% confidence intervals will be calculated. The statistically significant level will be set at 0.05. Also, a linear regression analysis will be performed to examine the effects of independent variables on continuous dependent variables. Dissemination: The study findings will be published in an academic peer-reviewed journal, and the abstract will be presented at an international conference. English and French visual and video abstracts of the methods and key findings will be designed and disseminated widely on social media. Highlights:
