Pediatric tumors of the central nervous system are the most common cause of cancer-related death in children. The five-year survival rate for high-grade gliomas in children is less than 20%. Due to their rarity, the diagnosis of these entities is often delayed, their treatment is mainly based on historic treatment concepts, and clinical trials require multi-institutional collaborations. Here we present the CBTN-CONNECT-DIPGR-ASNR-MICCAI BraTS-PEDs challenge, focused on pediatric brain tumors with data acquired across multiple international consortia dedicated to pediatric neuro-oncology and clinical trials. The CBTN-CONNECT-DIPGR-ASNR-MICCAI BraTS-PEDs challenge brings together clinicians and AI/imaging scientists to lead to faster development of automated segmentation techniques that could benefit clinical trials, and ultimately the care of children with brain tumors.

儿童中枢神经系统肿瘤是导致儿童癌症相关死亡的最常见原因之一，高级别胶质瘤的五年存活率不到20%，由于它们的罕见性，这些实体的诊断经常延迟，治疗主要基于历史性治疗概念，临床试验需要多机构合作。本研究介绍了CBTN-CONNECT-DIPGR-ASNR-MICCAI BraTS-PEDs挑战赛，专注于儿童脑肿瘤，数据来自多个国际联盟，致力于儿童神经肿瘤学和临床试验。人工智能/图像科学家与临床医生一同努力，以加快自动化分割技术的发展，这将有助于临床试验，并最终改善儿童脑肿瘤患者的治疗。
