Optimal Timing for Chemo Post-Brain Surgery

Researchers have found that the timing of chemotherapy after surgery to remove a glioblastoma, one of the most aggressive types of brain cancer, can significantly enhance its effectiveness. They demonstrated that a temporary disruption of the blood-brain barrier following surgery allows better drug delivery, especially during two specific time windows—around 15 minutes and 48-72 hours post-operation—which may reduce the chances of tumor recurrence. These preliminary results are important because they could pave the way for developing new treatment strategies that utilize these windows more intelligently, while emphasizing the need for further clinical studies.
