To determine the frequency of pediatric brain tumors treated at the University Pediatric Hospital of Puerto Rico over a 6-year period and examine the demographic data and tumor histology of patients in different age groups.
A retrospective study was undertaken at the University Pediatric Hospital. We included patients with brain tumors that had been newly diagnosed during the period covering from January 2002 to December 2007. All cases were analyzed by age, gender, histologic diagnosis, and affected area.
One hundred thirty-six patients were included in the study. Overall, males were more frequently affected than were females. Children in the 1 to 4 years old age group had the highest number of newly diagnosed brain tumors. Regarding anatomic location, supratentorial tumors were more frequent than were infratentorial tumors. The most common single tumor was the pilocytic astrocytoma (WHO grade I), representing 31% of the total pediatric brain tumors.
Our results provide an objective platform for further epidemiological studies and for the development of local health strategies for the timely diagnosis and treatment of the most common pediatric tumors in Puerto Rico.
确定波多黎各大学儿科医院在6年期间治疗的小儿脑肿瘤的发生率，并检查不同年龄组患者的人口统计学数据和肿瘤组织学。
在波多黎各大学儿科医院进行了一项回顾性研究。我们纳入了2002年1月至2007年12月期间新诊断为脑肿瘤的患者。所有病例均按年龄、性别、组织学诊断和受累部位进行分析。
136例患者纳入研究。总体而言，男性比女性更易受累。1至4岁年龄组的儿童新诊断脑肿瘤的数量最多。关于解剖位置，幕上肿瘤比幕下肿瘤更常见。最常见的单一肿瘤是毛细胞型星形细胞瘤（世界卫生组织I级），占小儿脑肿瘤总数的31%。
我们的结果为进一步的流行病学研究以及制定波多黎各最常见小儿肿瘤的及时诊断和治疗的地方卫生策略提供了一个客观平台。
