Photodynamic diagnosis of shed prostate cancer cells in voided urine treated with 5-aminolevulinic acid
BACKGROUND Past attempts at detecting prostate cancer (PCa) cells in voided urine by traditional cytology have been impeded by undesirably low sensitivities but high specificities. To improve the sensitivities, we evaluate the feasibility and clinical utility of photodynamic diagnosis (PDD) of prostate cancer by using 5-aminolevulinic acid (5-ALA) to examine shed prostate cancer cells in voided...
متن کاملPhotodynamic therapy of human glioma spheroids using 5-aminolevulinic acid.
The response of human glioma spheroids to 5-aminolevulinic acid (ALA)-mediated photodynamic therapy (PDT) is investigated. A two-photon fluorescence microscopy technique is used to show that human glioma cells readily convert ALA to protoporphyrin IX throughout the entire spheroid volume. The central finding of this study is that the response of human glioma spheroids to ALA-mediated PDT depend...
متن کاملPhotodynamic Detection of Peritoneal Metastases Using 5-Aminolevulinic Acid (ALA)
In the past, peritoneal metastasis (PM) was considered as a terminal stage of cancer. From the early 1990s, however, a new comprehensive treatment consisting of cytoreductive surgery and perioperative chemotherapy has been established to improve long-term survival for selected patients with PM. Among prognostic indicators after the treatment, completeness of cytoreduction is the most independen...
متن کاملPhotodynamic diagnosis (PDD) using 5-aminolevulinic acid-supplemented cultures of human endometrial epithelial cells.
PURPOSE The studies were aimed at monitoring 5-aminolevulinic acid (5-ALA)-dependent accumulation of endogenous protoporphyrin IX (PpIX) in epithelial cells originating from normal endometrium or endometriotic foci, as related to steroid treatment. MATERIAL AND METHODS Epithelial cells were cultured in presence of estradiol-17 beta (E2) and progesterone (P) in concentrations typical for the f...
