Abstract

Photodynamic therapy (PDT) of superficial basal cell carcinoma (sBCC) using topical 5-aminolevulinic acid (ALA) and a light fluence of 75-100 J cm(-2) yields unsatisfactory long-term results. In several animal models, illumination with two light fractions 2 hours apart was considerably more effective than single illumination. Response is further enhanced if the fluence of the first light fraction is reduced, although the cumulative fluence is maintained. We compared the response of sBCC to a single illumination and 2-fold illumination scheme in which two light fractions of 20 and 80 J cm(-2) are performed 4 and 6 hours after the application of a single dose of 20% ALA. We randomly assigned 154 patients with a total of 505 primary sBCC into two treatment groups. Two hundred and forty-three lesions were treated using a single illumination of 75 J cm(-2) at a fluence rate of 50 mW cm(-2). Fractionated PDT, at the same fluence rate, was performed on 262 lesions. The complete response (CR) following a 2-fold illumination scheme is significantly greater than that following a single light fraction (P=0.002, log-rank test). Twelve months after therapy, CR rate to a 2-fold illumination is 97%, whereas the CR to a single illumination is 89%.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Compared with single-illumination PDT, double-illumination PDT resulted in a significantly higher complete response rate at one year after treatment in patients with AK or superficial BCC lesions.

    “Compared with single-illumination PDT, double-illumination PDT resulted in a significantly higher complete response rate at one year after treatment in patients with AK [66] or superficial BCC [65] lesions.”
  • PDT protocols with fractionated light illumination enhance PDT outcomes.

    “PDT protocols with fractionated light illumination have been shown to enhance PDT outcomes [65].”
  • A double-illumination PDT scheme with 20 and 80 J/cm2 at 4 and 6 h after topical ALA application yields a much better clinical response than conventional single 75 J/cm2 illumination at 4 h after ALA.

    “Particularly, a double-illumination PDT scheme with 20 and 80 J/cm2 at 4 and 6 h after topical ALA application yields a much better clinical response than conventional single 75 J/cm2 illumination at 4 h after ALA.”

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.
