This clinical study reports outcomes from 157 consecutive patients with IDH‑mutant grade 2 gliomas infiltrating the corpus callosum who underwent connectome-guided awake surgery with callosectomy. It summarizes surgical technique, extent of resection, complication rates, return-to-work statistics, histology, adjuvant treatments, reoperations, and long-term overall survival.
Comparative analysis contrasts complete (total/supratotal) versus incomplete resections, showing higher extent of resection, greater reoperation potential, and longer median overall survival when callosal tumor was fully removed, while preserved function and a 96.8% return-to-work rate underline favorable onco-functional balance.
