Motivation While Photofrin PDT is an approved oncological therapy for multiple indications, its wider use is hindered by prolonged skin photosensitivity lasting several weeks. The aim of this study is to investigate intratumoral Photofrin administration as a way to decrease skin photosensitivity compared to the standard IV injection protocol. Tumor necrosis after PDT was assessed with immunohistochemical staining and Photofrin distributions by fluorescence microscopy. Results … READ MORE
Motivation for the study Glioblastoma is the most aggressive and lethal brain cancer with an average prognosis of 15 months. Fluorescence-guided surgery (FGS) for glioblastoma was FDA-approved in 2017, while photodynamic therapy (PDT) remains an active area of clinical investigation with very promising results so far. The aim of PDT is to eradicate the invasive cancer cells within 2 cm of the resected area where the glioblastoma most often… READ MORE
Results Illumination with one fiber Some level of tissue heating was observed at all used light intensities. At lower intensities (60-100 mW/cm), less than 5% of the tumor was subjected to >60 ⁰C temperature, a point where irreversible thermal damage will immediately occur (photothermal ablation). At intensities of 150-200 mW/cm, 15-20% of the tumor was at >60 ⁰C temperature. At 400 mW/cm, which is FDA-recommended light irradiance for iPDT, a… READ MORE

Background Professor Stummer on glioblastoma surgeries and iPDT: Treatment protocol 20 patients were treated. 5-ALA (Gliolan) was administered at a dosage of 20 mg/kg body weight 4 hours before anesthesia. Craniotomy was performed using FGR, with aim of maximal safe resection of the fluorescent tumor. Once there was no visible fluorescence or only tumor-infiltrated fluorescence in the eloquent areas left, PDT was performed. 1-4 cylindrical diffuser were strategically… READ MORE
Retinal Physician – May 1, 2021 Currently, most retina specialists use photodynamic therapy (PDT) with verteporfin (Visudyne; Bausch + Lomb). Photodynamic therapy devices include ML6710i (available for investigational use only in the United States) by Modulight and ML7710 (CE certified; available for investigational use only in the United States) by Modulight.… READ MORE
