Progress of photodynamic therapy in gastric cancer. [PDF]

Diagn Ther Endosc, 1999
Progress of photodynamic therapy (PDT) in gastric cancer and the clinical outcome are described in this paper. (1) We included the whole lesion and a 5 mm margin in the field for irradiation. Marking by injection of India‐ink showing the irradiation field was performed beforehand.

Photodynamic therapy for head and neck cancer. [PDF]

Diagn Ther Endosc, 1996
Photodynamic therapy (PDT) is a recently developed treatment involving the use of a photosensitizer and low power light, usually from a laser, to selectively destroy tumor cells. At present, we perform PDT for head and neck cancer using argon or excimer dye lasers with hematoporphyrin derivative as a photosensitizer.

Cooperative Clinical Trial of Photodynamic Therapy for Early Gastric Cancer With Photofrin Injection and YAG-OPO Laser. [PDF]

Diagn Ther Endosc, 1998
Background and Objective: Photodynamic therapy (PDT) treats malignant tumors using photosensitizers and light. We employed a new pulse laser as the excitation light source for PDT, i.e. an optical parametric oscillator (OPO) system pumped by a Q‐switched Nd:YAG laser, because it provides extremely high peak power.

Bronchoscopic Local Nd:YAG Laser Hyperthermia in the Treatment of Lung Cancer

Diagnostic and Therapeutic Endoscopy, Volume 1, Issue 3, Page 159-164, 1995., 1994
Between March 1989 and July 1990, 13 patients with tracheobronchial cancer were treated by laser hyperthermia at the National Cancer Center Hospital. A complete response was achieved in 9 patients (with 9 carcinoma lesions), with no evidence of local recurrence on follow‐up ranging from 4 to 29 months.

Photodynamic Therapy for Superficial Esophageal Cancer Using an Excimer Dye Laser

Diagnostic and Therapeutic Endoscopy, Volume 1, Issue 2, Page 99-105, 1994., 1994
In order to improve the therapeutic effectiveness of photodynamic therapy with Photofrin II and laser light for superficial esophageal cancer, we employed an excimer dye laser instead of an argon dye laser. Eight superficial esophageal cancer lesions (7 cases) were treated.

Photomedicine of the endometrium: experimental concepts [PDF]

, 2017
Gynaecological photomedicine offers new diagnostic and therapeutic methods based on the interaction of light with the reproductive organs. One example is photodynamic therapy (PDT) in which photosensitizers are applied systemically or topically for ...

Basic research on the biology of meta-tetra(hydroxyphenyl) chlorin for photodynamic therapy in gynaecology: Somatic genotoxicity assayed with Drosophila melanogaster [PDF]

, 2018
The well-established SMART test, a somatic mutation and recombination assay of Drosophila, was applied to assess the possible genotoxicity of sublethal meta-tetra(hydroxyphenyl) chlorin (mTHPC) photodynamic therapy (PDT) to clonogenic cells in situ.

Current evidence and applications of photodynamic therapy in dermatology [PDF]

, 2014
In photodynamic therapy (PDT) a photosensitizer – a molecule that is activated by light – is administered and exposed to a light source. This leads both to destruction of cells targeted by the particular type of photosensitizer, and immunomodulation ...

Resistance of Cancer Cells to Photodynamic Therapy with 5-aminolevulinic Acid: Role of the ABCG2 Transporter [PDF]

, 2017
Photodynamic Therapy (PDT) is a minimally invasive radiation therapy currently used in treatment of various cancerous and pre-malignant diseases. Photodynamic therapy with 5-aminolaevulinic acid (5-ALA/PDT) induces DNA damage following photoactivation of
