A fluorescence imaging device applied to the detection of early cancer is described. The app. is based on the imaging of laser-induced fluorescence of a dye that localizes in a tumor with a higher concn. than in the surrounding normal tissue after i.v. inj ...
The use of dyes has been helpful for the photodiagnosis of small cancers accessible to endoscopic examn. An important limiting factor of this technol. is that the presently used fluorescent dye mixt. has a relatively poor capacity to accumulate preferentia ...
The efficacy of photodynamic therapy (PDT) alone was evaluated on 41 ‘early’ squamous cell carcinomas of the pharynx (10), oesophagus (15) and tracheo-bronchial tree (16). All lesions but two were synchronous second primaries in ENT-patients suffering from ...
