Researchers identify key timing for brain cancer therapy
Studies on mice indicate that there is a short window of time after glioma (glioblastoma) tumor removal surgery during which drugs can cross the blood-brain barrier and reach the remaining cancer cells, thereby reducing the likelihood of recurrence. After surgery, the blood-brain barrier experiences disruptions in the first few hours, extending up to 48-72 hours. This period allows for more effective use of drug-loaded nanoparticles. Researchers also demonstrated that timing therapy within this window can make a significant difference in suppressing tumor growth before it returns. These findings suggest the potential to improve treatment effectiveness and decrease the chances of glioblastoma recurrence by synchronizing therapy with the post-surgical blood-brain barrier disruption period.
