BCIwiki (bciwiki.com) — Authors affiliated with Tianjin University in China, the University of California, San Francisco and collaborating institutions review BCI-related technologies in oncology in Frontiers in Immunology on October 21, 2026. The review covers cancer symptoms, brain tumor surgical support and disease mechanisms.
For symptom management, it discusses brain-signal interfaces based on neurofeedback and closed-loop regulation, including work on cancer pain and chemotherapy-induced peripheral neuropathy. The authors describe a direction in which feedback guides ongoing adjustment of neural states; clinical evidence needs to be assessed in the individual studies.
During brain tumor surgery, electrocorticography, high-density neural recording and real-time decoding can provide information on abnormal peritumoral networks and tumor-associated epilepsy. These techniques can complement function-guided surgery. Recording or decoding alone does not make a system a BCI, and these methods cannot replace direct electrical stimulation mapping.
The review also examines links between neural activity and glioma growth and invasion, alongside tumor-neural-immune interactions. The authors propose connecting symptom control, surgical decisions and disease mechanisms, while identifying challenges to clinical translation.
