摘要
背景:在巴西，估计在2020-2022年的三年期间，每年男性新发恶性中枢神经系统肿瘤(MCNST)为5870例，女性为5220例。本研究的目的是根据巴西2000年至2015年的肿瘤地形，分析发病率趋势并比较新发MCNST病例的人口统计学特征。方法:本研究包括从巴西国家癌症研究所(INCA)网站上提取的二级数据库的分析性横断面评估。数据包括从23个基于人群的癌症登记处检索的脑膜(C70)、脑(C71)、脊髓、脑神经和其他中枢神经系统部位(C72)的新发肿瘤病例。进行描述性分析。计算粗发病率和年龄调整后的发病率。使用线性最小二乘回归计算调整后发病率随时间的线性趋势。结果:共记录新发MCNST病例24 986例。主要地形为脑(91.5%)。除了脑膜肿瘤(女性占62.4%)外，在其他评估的地形中，MCNST病例在男性中更为常见。所有三种地形主要发生在40至64岁的成人患者中。2000年至2015年期间，发病率在5.12至4.95之间(每年增长1.4%;95% CI -4.0 ~ 6.8;P = .584)，从4.35增加到3.61(每年增加3.1%;95% CI -1.7 ~ 8.0;P = .189)。结论:最常见的地形是脑部。随着时间的推移，MCNST的发病率在两性中保持相对稳定。
Trends in the incidence of malignant central nervous system tumors in Brazil, 2000-2015.
Background: In Brazil, 5870 new cases of malignant central nervous system tumors (MCNST) were estimated for men and 5220 for women for each year of the 2020-2022 triennium. The objective of this study was to analyze incidence rate trends and compare demographic characteristics of new MCNST cases according to tumor topographies in Brazil from 2000 to 2015.
Methods: This study comprises an analytical cross-sectional assessment of secondary databases extracted from the Brazilian National Cancer Institute (INCA) website. Data comprised new neoplasm cases of meninges (C70), brain (C71), spinal cord, cranial nerves, and other central nervous system parts (C72) retrieved from 23 population-based cancer registries. A descriptive analysis was performed. Crude and age-adjusted incidence rates were calculated. Linear trends were calculated using a linear least squares regression for adjusted incidence rates versus time.
Results: A total of 24 986 new MCNST cases were recorded. The main topography was the brain (91.5%). Except for meninges tumors, where 62.4% of the cases were observed in women, MCNST cases were more frequent among men concerning the other evaluated topographies. All 3 topographies occurred predominantly in adult patients aged from 40- to 64-year-old. Between 2000 and 2015, incidence rates ranged from 5.12 to 4.95 (a 1.4% increase of per year; 95% CI -4.0 to 6.8; P = .584) in men and from 4.35 to 3.61 (a 3.1% increase per year; 95% CI -1.7 to 8.0; P = .189).
Conclusions: The most frequent topography was the brain. Incidence rates of MCNST remained relatively stable over time in both sexes.
期刊介绍：
Neuro-Oncology Practice focuses on the clinical aspects of the subspecialty for practicing clinicians and healthcare specialists from a variety of disciplines including physicians, nurses, physical/occupational therapists, neuropsychologists, and palliative care specialists, who have focused their careers on clinical patient care and who want to apply the latest treatment advances to their practice. These include: Applying new trial results to improve standards of patient care Translating scientific advances such as tumor molecular profiling and advanced imaging into clinical treatment decision making and personalized brain tumor therapies Raising awareness of basic, translational and clinical research in areas of symptom management, survivorship, neurocognitive function, end of life issues and caregiving
