To test and optimize photodynamic therapy of early cancers in the upper aero-digestive tract and esophagus, we sought an appropriate animal model, which was found in the 7,12-dimethylbenz[a]anthracene-induced early squamous cell carcinoma in the Golden Syr ...
Objective: To clinically evaluate a new photosensitizer, m- tetra(hydroxyphenyl) chlorin (m-THPC), for the photodynamic therapy of early squamous cell carcinomas of the upper aerodigestive tract. Design: Phase 1 included evaluation of the innocuousness of ...
For holographic biopsy purposes, holograms of biological tissue samples have been recorded in vitro to establish the possibility of differentiating tissues on the holograms. With the use of specific absorbing dyes for staining tissues, the contrast has bee ...
A fluorescence imaging device applied to the detection of early cancer is described. The apparatus is based on the imaging of laser-induced fluorescence of a dye that localizes in a tumor with a higher concentration than in the surrounding normal tissue af ...
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 ...
