Fluorescence-guided craniotomy of glioblastoma using panitumumab-IRDye800.
Fluorescence-guided craniotomy of glioblastoma using panitumumab-IRDye800. Neurosurgical focus: Video Zhou, Q., Li, G. 2022; 6 (1): V9Abstract
A contrast-enhancing lesion in the left temporal lobe of a 72-year-old woman was biopsied and diagnosed as glioblastoma. Near-infrared (NIR)-labeled epidermal growth factor receptor (EGFR) antibody, panitumumab-IRDye800, was infused 52 hours before craniotomy without pretreatment. Tumor fluorescence was detected through intact dura, and the visual contrast between disease and peritumoral healthy brain was enhanced after tumor exposure. Residual cancerous tissue was identified with strong fluorescence in resection cavity after en bloc tumor removal. Minimal fluorescence remained in the final wound bed, likely from nonenhancing tumor. Fluorescence was heterogeneously distributed at the infiltrative margin in resected tumor pieces imaged ex vivo. Postoperative MRI confirmed gross-total resection. The video can be found here: https://stream.cadmore.media/r10.3171/2021.10.FOCVID21201.
