Disparities in neuro-oncological care between high-income and low- and middle-income countries (LMICs) are well documented, yet region-specific data from Latin America remain limited. This review evaluates epidemiologic trends, access to care, and systemic challenges in brain tumor management across Latin American LMICs, using Argentina as a case study. A systematic review of peer-reviewed literature was conducted focusing on brain tumor incidence, mortality, risk factors, and availability of diagnostics and treatments in Latin America. Socioeconomic, cultural, and systemic barriers were also analyzed. Latin America exhibits some of the highest global brain tumor mortality rates, with Brazil reporting age-standardized rates exceeding 4.5 per 100,000. Glioblastomas are frequently diagnosed at younger ages, often in the fifth decade of life, compared to the global average. Meningioma incidence has increased by 15-20% over the last decade, yet region-wide data remain fragmented. Access to neuroimaging, neurosurgery, radiotherapy, and chemotherapy is limited, with up to 60% of patients relying solely on under-resourced public health systems. Less than 30% of hospitals in rural areas have MRI availability, and continuous professional training is infrequent. Innovative adaptations, such as awake craniotomy, are used in some LMIC centers in response to equipment scarcity. Brain tumor care in Latin America is hindered by limited epidemiological data, restricted access to diagnostics and treatment, and insufficient workforce training. Targeted investments in healthcare infrastructure, international educational collaborations, and policy-level reforms are critical to reducing disparities and improving outcomes in neuro-oncology across the region.
高收入国家与低收入和中等收入国家(LMICs)在神经肿瘤护理方面的差异已有充分记录,但拉丁美洲的特定区域数据仍然有限。本综述以阿根廷为例,评估了拉丁美洲低收入和中等收入国家脑肿瘤管理的流行病学趋势、医疗服务可及性以及系统性挑战。对同行评审文献进行了系统综述,重点关注拉丁美洲脑肿瘤的发病率、死亡率、风险因素以及诊断和治疗的可及性。还分析了社会经济、文化和系统性障碍。拉丁美洲的脑肿瘤死亡率在全球居高不下,巴西报告的年龄标准化死亡率超过每10万人4.5例。与全球平均水平相比,胶质母细胞瘤的诊断年龄往往较轻,通常在50岁左右。在过去十年中,脑膜瘤发病率增加了15%-20%,但全区域数据仍然零散。神经影像学、神经外科、放疗和化疗的可及性有限,高达60%的患者仅依赖资源不足的公共卫生系统。农村地区不到30%的医院具备磁共振成像设备,持续专业培训也很少见。一些低收入和中等收入国家的中心采用了如清醒开颅手术等创新方法来应对设备短缺问题。拉丁美洲的脑肿瘤护理受到流行病学数据有限、诊断和治疗可及性受限以及劳动力培训不足的阻碍。有针对性地投资于医疗基础设施、开展国际教育合作以及进行政策层面的改革,对于减少该地区神经肿瘤学方面的差异并改善治疗效果至关重要。
