Abstract

BACKGROUND: Photodynamic therapy (PDT) is an established, minimally invasive treatment for specific types of cancer. During PDT, reactive oxygen species (ROS) are generated that ultimately induce cell death and disruption of the tumor area. Moreover, PDT can result in damage to the tumor vasculature and induce the release and/or exposure of damage-associated molecular patterns (DAMPs) that may initiate an antitumor immune response. However, there are currently several challenges of PDT that limit its widespread application for certain indications in the clinic. METHODS: A literature study was conducted to comprehensively discuss these challenges and to identify opportunities for improvement. RESULTS: The most notable challenges of PDT and opportunities to improve them have been identified and discussed. CONCLUSIONS: The recent efforts to improve the current challenges of PDT are promising, most notably those that focus on enhancing immune responses initiated by the treatment. The application of these improvements has the potential to enhance the antitumor efficacy of PDT, thereby broadening its potential application in the clinic.

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

  • PDT produces ROS that cause oxidative damage to targeted cells, including bacteria, fungi, parasites, viruses, and cancer cells, without significantly harming healthy tissues.

    “This combination produces ROS, which can cause oxidative damage to targeted cells, including bacteria, fungi, parasites, viruses, and cancer cells, without significantly harming healthy tissues [134,135].”

    From Emerging Applications of Chlorella sp. and Spirulina (Arthrospira) sp. (2023) · cites this paper as [134]

    The Introduction says PDT generates ROS that can initiate cell death, and Section 4 describes damage to tumor cells. Section 4.2 reports that vessels surrounding a treated tumor area remained intact in one setting, but it does not establish that healthy tissues generally avoid significant harm. The cited passages do not support the added list of bacteria, fungi, parasites, and viruses as targeted cells. (LLM, conf=0.88)

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.
