text: Aminolevulinic acid utilization is promising in the field of cancer delineation, particularly in the context of fluorescence-guided surgery. This compound is utilized to enhance the visualization of malignant tissues during surgical procedures. When administered to patients, 5-ALA is metabolized to protoporphyrin IX (PpIX) preferentially in cancer cells, leading to their fluorescence under specific light wavelengths. This fluorescence aids surgeons in real-time identification and precise removal of cancerous tissue, reducing the likelihood of leaving residual tumor cells behind. This innovative approach has shown success in various cancer types, including brain and spine gliomas, bladder cancer, and oral squamous cell carcinoma.
