title: [Potential and limitations of fluorescence diagnosis and photodynamic therapy. Part I: Fluorescence diagnosis].
abstract: Fluorescence diagnostic methods enable tumor visualization via specific excitation of endogenous or exogenous tumor-selective fluorescent markers and subsequent optical measurement of the induced fluorescence signals. In the following review, the reader will be given a clear and extensive understanding of all aspects of these methods relevant for ENT specialists. Apart from a demonstration of the clinical difficulties in the diagnosis of malignant tumors of the upper aerodigestive tract, a historical synopsis of fluorescence diagnosis and an explanation of the biophysical basics, this publication focuses mainly on a detailed discussion of the current status of research and a critical consideration of the commercially available systems for fluorescence diagnosis in ENT oncology. The topic is rounded off by a short account of possible future activities in this field.
