Abstract

The main advantage of photodynamic therapy (PDT) in laryngology seems to be its non-invasiveness and the possibility of using it despite previous application of conventional methods. In the study, we gave PDT to two separate groups of patients, i.e. five patients with advanced tumour (four of them with local recurrence (squamous cell carcinoma) after surgery and radiotherapy and one with a primary hypopharyngeal tumour) and five patients with leucoplakia. In the first group delta-aminolaevulinic acid (ALA) was administered orally (dose 3 g), while in the second, an ointment containing 10% ALA was applied locally. In both groups prior to irradiation, the tissue level of protoporphyrin IX was verified using an adapted Xillix Life instrument. All treated lesions were irradiated with an argon-pumped dye laser (dose range 100-250 J/cm2, wavelength 635 nm). In the first group, partial response was obtained. In these advanced cases, diminution of cancerous ulcerations was observed. In the leucoplakia group, complete response was achieved in four out of five treated patients. On the basis of our preliminary results, PDT may be useful in eradicating premalignant lesions of the oral cavity and in the palliation of advanced lesions of the oropharynx and larynx.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
