title = "Comparative study of two routes of administration of 5-aminolevulinic acid (oral and intratumoral via) and their effect on the accumulation of PpIX in tissues in murine model of breast cancer",
abstract = "Protoporphyrin IX (PpIX) is a photosensitizer synthesized from 5-aminolevulinic acid (ALA) that has been used in photodynamic therapy (PDT) as a promising treatment for many types of cancer. In this work it was quantified the accumulation of PpIX in tumors and in different tissues of female mice (nu/nu) inoculated with breast cancer cells. Two routes of administration of ALA: gastric probe and intratumoral injection were used to find optimum time of accumulation and the via that induce the higher quantity of PpIX to improve the efficiency of PDT. The results show that the accumulation of PpIX using the intratumoral via is two times bigger than the oral via in tumors at 8 h of treatment. The concentrations obtained in the different tissues are not physiologically significant.",
