Surgical Clinics of North America, 1992
Photodynamic therapy is an experimental method for treating malignant tumors. Injection of a tumor-localizing and photosensitizing agent and its subsequent activation by an appropriate wavelength of light can lead to tumor destruction, apparently through disruption of the vascular integrity of the neoplasm.

Photodynamic therapy (PDT) relies on the interaction between a photosensitizer, the appropriate wavelength, and oxygen to cause cell death. First introduced about 100 years ago, PDT has continued to evolve in dermatology into a safe and effective treatment option for several dermatologic conditions.

Photodynamic Photorejuvenation
Dermatologic Surgery, 2002The visible signs of photodamage are characterized by wrinkling, coarse skin texture, pigmentation alterations, telangiectases, and in some case actinic keratosis (AKs). Intense pulsed light (IPL) photorejuvenation has been shown to improve each of the different components of photodamaged skin except AKs.To present photodynamic therapy with topical 5 ...

Photodynamic therapy for treatment of malignant tumors uses certain porphyrins as relatively tumor-selective photosensitizers. A wide variety of tumors take up and retain these materials, which can result in complete eradication of the local tumor provided that light of the proper wavelength and sufficient dose is used.

ALA-PDT is a safe, well-tolerated, and effective treatment for many dermatologic conditions. Current data most strongly support its use in the treatment of actinic damage, but further investigation into alternative uses continues. Current efficacy is limited primarily by the depth of penetration of the photosensitizing agent and the activating light ...

Photodynamic therapy (PDT) is a photochemical process that uses a photosensitizer drug activated by laser light to produce mucosal ablation. Porfimer sodium PDT has proved long-term efficacy and durability in the treatment of Barrett's esophagus and high-grade dysplasia and early esophageal adenocarcinoma.

Photodynamic Photorejuvenation
Dermatologic Surgery, 2016Topical photodynamic therapy (PDT) is acknowledged to be a safe and efficient therapeutic option for the selective destruction of actinic keratosis and superficial carcinomas. Over the past 15 years, topical PDT has also been shown to be a possible method for "photorejuvenation."An extensive review was performed of in vitro and in vivo (animals, organ ...

Photodynamic therapy (PDT) is an innovative approach to the local ablation of malignant tumours. It has attracted a great deal of interest as a possible means of selectively destroying small cancers. The concept is simple:

Photosensitizers for Photodynamic Therapy
Advanced Healthcare Materials, 2019AbstractAs an emerging clinical modality for cancer treatment, photodynamic therapy (PDT) takes advantage of the cytotoxic activity of reactive oxygen species (ROS) that are generated by light irradiating photosensitizers (PSs) in the presence of oxygen (O2).

Photodynamic Therapy in Gynecology
Obstetrics and Gynecology Clinics of North America, 1991PDT is a technique in which visible light is used in combination with photosensitizing agents to achieve a tumoricidal effect. Hematoporphyrins are the most commonly used photosensitizers in clinical practice. DHE is the active fraction of hematoporphyrin. Intravenously injected DHE is found in highest concentration in the liver followed by the spleen,
