Supplying 5-aminolevulinic acid (ALA), a precursor in the biosynthetic pathway to heme from an external source leads to an accumulation of the endogenous fluorescent photosensitizer protoporphyrin IX (PPIX). Following instillation of ALA in the urinary bladder neoplastic tissue can be discerned by fluorescence cystoscopy or treated by illumination with light of an appropriate wavelength. In order ...
