The paper reviews fluorescence (photodynamic) diagnostic approaches in gynecology based on exogenous 5-aminolevulinic acid–induced accumulation of protoporphyrin IX, noting that dysplastic tissues show higher fluorescence contrast than normal tissue. It reports that, in cervical settings, fluorescence diagnosis can increase detection sensitivity for neoplastic and pre-neoplastic changes, while in ovarian cancer multiple studies suggest improved identification of peritoneal metastases and involved lymph nodes. For endometriosis, it describes that during diagnostic laparoscopy non-pigmented lesions can be identified more effectively, while emphasizing that further studies are required before broad routine gynecologic use. This paper is centrally about endometriosis — it specifically discusses use of 5-aminolevulinic acid–induced fluorescence in diagnostic laparoscopy to better detect non-pigmented endometriotic lesions.

Zusammenfassung Die Fluoreszenzdiagnostik ist ein modernes Verfahren zur Evaluierung neoplastischer und nichtneoplastischer Läsionen an der Oberfläche von Organsystemen. Ein potenter Photosensibilisator ist dabei das Protoporphyrin IX, das durch exogene Zufuhr von 5-Aminolävulinsäure intrazellulär angereichert werden kann. Dabei weisen dysplastische Gewebe höhere Konzentrationen als Normalgewebe auf. Der entstehende Kontrast wird in verschiedenen Bereichen der Gynäkologie erforscht und genutzt. Im Bereich der Zervix kann die Fluoreszenzdiagnostik die Erkennungsrate neoplastischer und präneoplastischer Veränderungen erhöhen. Beim Ovarialkarzinom weisen mehrere Studien auf den möglichen Einsatz dieses Verfahrens zur besseren Identifizierung einer peritonealen Metastasierung sowie befallener Lymphknoten hin. In der Endometriosediagnostik können im Rahmen einer diagnostischen Laparoskopie vor allem nichtpigmentierte Herde besser identifiziert werden. Weitere Studien in diesen und anderen Gebieten sind bis zum breiten klinischen Einsatz gefordert. Abstract Fluorescence diagnosis constitutes a modern method for evaluating neoplastic and non-neoplastic lesions located on the surface of organ systems. Protoporphyrin IX is a potent photosensitizer which can be accumulated intracellulary by the exogenic supply of 5-aminolevulinic acid. Thereby, dysplastic tissues present higher concentrations then normal tissues. The arising contrast is utilized therapeutically in different gynaecological fields. In terms of the cervix uteri, fluorescence diagnosis can raise the sensitivity for detecting neoplastic and pre-neoplastic changes. In ovarian cancer, different studies provide evidence for its possible use to better identify peritoneal metastases and positive lymph nodes. When performing diagnostic laparoscopy on the suspicion of endometriosis, this method is especially useful in identifying non-pigmented lesions. Further studies in these and other fields are required in order to introduce fluorescence diagnosis into routine gynaecological use.
