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.

Photoradiation therapy of gynecologic malignancies [PDF]

, 1984
Four patients with gynecologic tumors recurrent either to the vagina or skin were treated with photoradiation therapy. A cytotoxic effect on the tumor was achieved by injecting hematoporphyrin derivative intravenously followed by exposing the treatment ...

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.

Effectiveness of Laser Photoradiation Therapy following Hematoporphyrin Derivative Administration in the Experimental MS-2 Tumor Model

, 1983
The effectiveness of laser photoradiation therapy with hematoporphyrin derivative sensitization was tested in the MS-2 sarcoma. This solid tumor, transplanted into the pad of the hind leg of BALB/c mice, was found to be a sensitive experimental model ...

Photoradiation Therapy for Cutaneous and Subcutaneous Malignancies

, 1981
Photoradiation therapy (PRT) using hematoporphyrin derivative (Hpd) as the photosensitizing agent is being developed for local treatment of a wide variety of malignant lesions including those involving the skin.

Hyperthermal Effects in Phototherapy with Hematoporphyrin Derivative Sensitization

, 1984
Although the photochemical reaction of hematoporphyrin derivative (HpD) appears to play a major role in cytotoxic activity, the hyperthermal contribution to tumor destruction has not yet been clarified.
