The use of 5-aminolevulinic acid and its esters to induce endogenous porphyrins for the purpose of detection of epithelial cancers is being studied extensively in many centres around the world. The challenge is to prepare an efficacious formulation for the purpose of cancer detection. Photodynamic diagnosis of cancer using 5-aminolevulinic acid (ALA) and its ester derivatives is being actively investigated. In this study, we compared ALA with ALA methyl ester (AME) derivative in terms of PpIX fluorescence intensity in in vitro and in vivo systems of bladder carcinoma. For the in vivo system consisting of RT112 xenografts, the modes of …
