Abstract

Photodynamic therapy (PDT) using topical porphyrin-precursors is a promising treatment for superficial basal cell carcinoma (sBCC), but it needs further optimization. The aim of this study was to compare 5-year lesion (complete) response rates of sBCC treated with topical aminolaevulinic acid (ALA)-PDT using a single illumination vs. ALA-PDT using a 2-fold illumination scheme. A prospective, randomized study was performed, in which 91 patients with 299 lesions were treated with a 2-fold illumination scheme with 2 light fractions of 20 and 80 J/cm2 delivered 4 and 6 h after a single application of 20% ALA, and 106 patients with 274 lesions were treated with a single illumination of 75 J/cm2 4 h after a single application of 20% ALA. All lesions were treated at a fluence rate of 50 mW/cm2. An interim time to event analysis of complete response (CR) rates at 12 months showed encouraging results, and therefore lesions were followed for 5 years post-therapy. A third group of 50 patients with 172 lesions treated with 2-fold illumination were included after the initial period and analysed separately. The CR rate was significantly greater following the 2-fold illumination than the single illumination (p = 0.0002, log-rank test). Five years after therapy the CR rate after 2-fold illumination was 88%, whereas the CR rate after single illumination was 75%. The CR rate in the third group of lesions, treated with 2-fold illumination was 97% and 88% at 12 months and 5 years after therapy, respectively. Long-term follow-up indicates superior efficacy in sBCC of ALA-PDT with 2-fold illumination compared with ALA-PDT with single illumination.

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.
