The purpose of the study is to determine whether connectome-guided navigation-assisted microsurgical resection can better preserve neurological function after surgery than conventional tractography-guided surgery.\n\nParticipants who meet the study criteria will be assigned to one of two surgical planning strategies. In the experimental group, patients will undergo preoperative diffusion tensor imaging and resting-state functional MRI for individualized brain network reconstruction, and these data will be integrated with intraoperative navigation and neurophysiological monitoring to guide the resection boundary. In the control group, surgery will be guided by conventional DTI tractography-assisted navigation.\n\nThe main outcome is the rate of postoperative functional preservation. Other outcomes include extent of tumor resection, postoperative complications, time to neurological recovery, overall survival, and quality of life. Patients will be evaluated before surgery and followed after surgery with clinical examinations, neurological assessments, and MRI at prespecified time points.",[26,27],"Brain Neoplasms","Eloquent Area Brain Tumors",[29,30,31,32,33,34,35,36,37],"Connectome-guided surgery","Eloquent area brain tumor","Brain network navigation","Diffusion tensor imaging","DTI tractography","Resting-state fMRI","Functional preservation","Microsurgical resection","Intraoperative neurophysiological monitoring","RECRUITING","2026-06-14",{"date":41,"type":42},"2026-06-18","ACTUAL",{"date":44,"type":42},"2025-11-01",{"date":46,"type":20},"2028-12-31",{"name":48,"class":49},"Cancer Institute and Hospital, Chinese Academy of Medical Sciences","OTHER"]
