New insight into brain cancer recurrence
A recent study indicates that there is a short time window after brain cancer surgery during which medications can cross the blood-brain barrier and reach remaining cancer cells, potentially helping to reduce tumor recurrence. The results showed that the blood-brain barrier is disrupted within the first few hours after glioblastoma removal, as well as during 48 and 72 hours post-operation. Nano-sized particles loaded with the chemotherapy drug doxorubicin were able to reach the resection edge, an area highly susceptible to tumor return. The study suggests that leveraging this time period could enhance treatment delivery effectiveness and help decrease the likelihood of recurrence, although the research is still in the animal testing phase.
