Photodynamic Therapy for Esophageal Cancer [PDF]

Clinical Endoscopy, 2021
Photodynamic therapy, a curative local treatment for esophageal squamous cell carcinoma, involves a photosensitizing drug (photosensitizer) with affinity for tumors and a photodynamic reaction triggered by laser light.

Photodynamic therapy [PDF]

Journal of the Royal Society of Medicine, 1999
Photodynamic therapy (PDT) of malignant tumours is a new technique for treating cancers. After intravenous injection, a photosensitiser is selectively retained by the tumour cells so after time there is more sensitiser in the tumour than in the normal adjacent tissue. The photosensitiser must be able to absorb the wavelength of light being delivered to

Photodynamic Therapy [PDF]

JNCI Journal of the National Cancer Institute, 1998
Photodynamic therapy involves administration of a tumor-localizing photosensitizing agent, which may require metabolic synthesis (i.e., a prodrug), followed by activation of the agent by light of a specific wavelength. This therapy results in a sequence of photochemical and photobiologic processes that cause irreversible photodamage to tumor tissues ...

Synthetic biology-instructed transdermal microneedle patch for traceable photodynamic therapy

Nature Communications, 2022
5-Aminolevulinic acid-based photodynamic therapy heavily depends on the biological transformation efficiency of 5-aminolevulinic acid to protoporphyrin IX, while the lack of an effective delivery system and imaging navigation are major hurdles in ...

Microscopic study of cultural and diffusion kinetics of the effects of a prototype extracellular matrix on the photodynamic therapy of periopathogenic bacteria – a pilot study [PDF]

Folia Medica, 2023
Introduction: In dental medicine, photodynamic therapy is a promising treatment for bacterial infections. Oral biofilms, on the other hand, can produce an extracellular matrix that provides protection and stability against external forces.
