Summary

This trial is testing a new way to help surgeons remove brain tumors by using a dye that makes the tumor boundaries easier to see.

Who is the study for?
This trial is for adults over 21 with a brain tumor diagnosis suitable for surgery, without serious psychiatric illnesses. It's not for pregnant or breastfeeding women, those with photosensitivity issues, recent liver disease, dermatitis, or high creatinine levels.
What is being tested?
The study tests the use of a substance called 5-aminolevulinic acid (ALA) to make tumor cells glow during surgery. This could help surgeons see and remove the entire tumor more effectively.
What are the potential side effects?
Potential side effects may include skin sensitivity to light due to ALA. Patients must take precautions against exposure to bright lights before and after receiving this treatment.
