The STRATUM project has reached a significant milestone with the successful use of the first STRATUM hyperspectral acquisition system (V1.0) prototype during a neurosurgical procedure at the Hospital Universitario de Gran Canaria Dr. Negrin (HUGCDN) in Las Palmas de Gran Canaria (Spain) on July 7th, 2025.
The surgeons Sara Bisshopp and Alejandro Tabes, from the Department of Neurosurgery at HUGCDN performed the surgical procedure. The researchers Himar Fabelo, Raquel León, and Laura Quintana, from the University of Las Palmas de Gran Canaria (ULPGC), ensured the seamless integration of the prototype into the surgical workflow to capture hyperspectral data of the exposed brain tumour tissue.
This surgery initiates the recruitment at HUGCDN of the Observational Study of the STRATUM project (STRATUM-OS: https://www.clinicaltrials.gov/study/NCT07036783). The objective of this study is to collect multimodal high-quality data (pre, intra and postoperative) essential for the development and technical validation of a 3D decision support tool for brain surgery guidance and diagnostics integrating augmented reality and multimodal data processing powered by artificial intelligence algorithms (STRATUM tool). Additionally, patients from STRATUM-OS will act as a historical control group in the subsequent historically controlled clinical trial (STRATUM-NRCCT) to clinically validate the STRATUM tool, which will be performed once STRATUM-OS has been completed.
The deployment was the result of months of preparation, close collaboration between engineers, clinicians, and researchers, and extensive pre-clinical testing. As expected, during the procedure, the system optimally captured data without disrupting the surgical workflow.
In the coming months, the STRATUM consortium will continue collecting surgical data within STRATUM-OS to increase the number of patients in the database, including the other two clinical sites: Hospital Universitario 12 de Octubre (Madrid, Spain) and Karolinska University Hospital (Stockholm, Sweden).
