However, reliable methods for efficient CGCs capture and comprehensive clinical evaluation on whether CGCs could faithfully represent complicated heavy equipment (such as MRI) remain insufficiently explored. Here, we present an antibody modification and size screening-based microfluidic (ASM) chip for effectively capturing CGCs, specifically designed for potential clinical translational applications. The ASM chip consists of one inlet, three outlets, one white blood cell clearance area, and one CGC capture area. The performance of the chip was optimized with two typical cell subtypes, namely SU-DHL-4 (to simulate leukocytes) and U251MG-ZsGreen (to simulate CGCs), and the capture rate reached more than 96% ata flow rate of 1 .2 mL/h. In real-life applications, CGCs (1–25/mL) were detected in 21 out of 35 glioma patients. We found that the number of CGCs was relatively high in patients with wild-type IDH1 and was positively correlated with Ki67 expression (p = 0.026) . The enrichment of CGC was correlated with neutrophils (p = 0.041) and heparin-binding protein (p = 0.0064), suggesting neutrophil-mediated metastasis. Radiomics linked a higher presence of CGCs with larger tumors, severe necrosis, and extensive edema, suggesting a poor prognosis for patients. The ASM chip can effectively capture and quantify CGCs for guiding the diagnosis and predicting the potential prognosis of clinical glioma patients.  \nIntroduction  \nCancer-related death is the second leading cause of human mortality1. It is estimated that up to 90% of cancer deaths are caused by metastatic cancer2. When tumor cells break away from the primary tumor, enter the peripheral bloodstream, and circulate throughout the body, they are referred to as circulating tumor cells (CTCs)3. Upon adapting to the selective pressures of the new microenvironments in various tissues, these cells establish secondary malignant growths, ultimately resulting in cancer-related mortality. Glioma is the most common invasive cancer of the central nervous system (CNS),  \nCorrespondence: Xianting Ding ([dingxianting@sjtu.edu.cn](dingxianting@sjtu.edu.cn))  \nBangbao Tao ([taobangbao@xinhuamed.com.cn](taobangbao@xinhuamed.com.cn))  \n1Department of Neurosurgery, Xinhua Hospital, Shanghai Jiao Tong University School of Medicine, No 1665 Kongjiang Road, Shanghai 200092, China 2State Key Laboratory of Oncogenes and Related Genes, Institute for Personalized Medicine, Shanghai Jiao Tong University, Shanghai 200030, China Full list of author information is available at the end of the article  \nThese authors contributed equally: Hengxing Su, Aynur Abdulla  \naccounting for 75% of primary intracranial tumors in adults4. The median survival time for patients’ postdiagnosis is extremely short, typically ranging from 12 to 15 months5,6. Traditionally, it is believed that this type of tumor is confined to the CNS because even the incidence of extracranial metastasis of glioblastoma, which is the most malignant, is extremely low (occurring in only 0.4–0.5% of patients), mainly metastasizing to bones, lymph nodes, lungs, and liver7–9. However, recent studies have indicated that circulating glioma cells (CGCs) are present in the peripheral blood of patients with glioma and display stem cell characteristics10, 11.  \nCurrently, there are four methods for capturing and detecting CGCs.
