Abstract

Photodynamic therapy involves the activation of an exogeneously administered, or an endogenously gen‐erated, photosensitizer with light to produce localized tissue destruction. It is an attractive, predominantly endosopic technique for the palliation of advanced upper gastrointestinal cancer and the eradication of early neoplastic and pre‐neoplastic lesions. The nature of the biological response allowing safe healing and the exploitation of tissue threshold effects mean that adjacent tissue damage can be minimized. This review used a database of 368 papers. The nature of the photosensitizer is critical to the depth of tissue damage and the risk of adjacent tissue damage and stricture formation. The generation of protoporphyrin IX following administration of 5‐aminolaevulinic acid has proved useful for the treatment of high‐grade dysplasia in Barrett’s oesophagus. A double‐blind randomized placebo controlled trial has confirmed that it is a safe and effective method for the ablation of low‐grade dysplasia. The treatment of more advanced lesions requires exogeneously administered photo‐sensitizers. However, recent data indicate that the neoplastic potential remains in some patients and continued follow‐up is necessary. Photodynamic therapy can be used to eradicate early neoplasia and palliate advanced cancer, but caution is required before a definitive cure can be claimed.

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?

  • Therapies of high-grade dysplasia and metaplasia of Barrett's esophagus rely on preferential uptake of ALA, which is 3.5 times greater in mucosa than in muscles.

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.
