Lasers Improve Phototherapy-Drug Delivery Platform
BALTIMORE, Nov. 7, 2023 — Photoimmunotherapy targets cancer cells with microscopic, nano-engineered cancer drugs that are light-activated at the lesion site. Although the technology is increasingly used to treat metastatic cancer, tools to improve the effectiveness of photoimmunotherapy in gynecologic oncology have been lacking. Responses to treatment vary from person to person, and no method has existed to readily monitor whether the drugs are delivered effectively or have the desired

New Light-Activated Metal Compound Kills Cancer Energy Source
COVENTRY, England, Oct. 18, 2019 — A team led by University of Warwick researchers is using light to activate a cancer-killing compound that attacks a vital energy source in cancer cells. This technique could be used not only to treat cancer, but also to help reduce side effects of...
Photodynamic Therapy Could be Made Easier With NIR Light Absorbing Molecule
WORCESTER, Mass., Jan. 3, 2017 — The clinical application of photodynamic therapy (PDT) could be enhanced through the use of a novel class of molecules. The carbazole-substituted BODIPY (Car-BDP) molecule has an intense, broad NIR absorption band (600–800 nm) with a high...
Concordia’s Photodynamic Therapy Laser Receives Premarket Approval
OAKVILLE, Ontario, July 19, 2016 — Concordia International Corp. said that the U.S. Food and Drug Administration has approved the Company's premarket approval application for its Photofrin 630 PDT (photodynamic therapy) Laser.
Drug Fluoresces, Kills Cancer Under 1 Wavelength
CORVALLIS, Ore., Jan. 6, 2015 — A combined imaging and phototherapy technique could help guide surgeons removing chemotherapy-resistant tumors — and kill any cancer cells the surgeons miss. Researchers at Oregon State University said their technique completely prevented...
Penn Researchers Get $8M to Study Effects of PDT on Lung Cancer
PHILADELPHIA, July 10, 2014 — An $8 million grant from the National Cancer Institute will fund a four-year study of the effects of photodynamic therapy (PDT) on a rare lung cancer associated with asbestos. The study, involving 102 patients diagnosed with malignant pleural...
Light-Based Approach Pushes PDT Deeper into Body Tissue
BUFFALO, N.Y., May 16, 2014 — Photodynamic therapy (PDT) for years has proven to be an effective cancer treatment, although only on easily accessible tumors such as in oral and skin cancers. A new technique — developed by a team from the University at Buffalo in...
