Photodynamic therapy for cancer of the pancreas [PDF]

, 2002
Background: Few pancreatic cancers are suitable for surgery and few respond to chemoradiation. Photodynamic therapy produces local necrosis of tissue with light after prior administration of a photosensitising agent, and in experimental studies can be ...

Selenium‐Integrated Cyanine Dye With Enhanced Photophysical Properties for Optoacoustic‐Guided Cancer Imaging and Therapy

Advanced Functional Materials, EarlyView.
This study introduces selenium‐integrated cyanine dye (Se‐Cyn), with superior photostability, absorption, and photothermal efficiency, outperforming ICG in NIR window. Its nanoparticle form remains stable in water, accumulates in tumors, and enables strong optoacoustic imaging and effective phototherapy outcomes.

Photodynamic Therapy in Gastroenterology

Journal of Gastrointestinal Cancer, 2013
Photodynamic therapy (PDT) is a minimally invasive and promising new modality to combat cancer. Upon illumination and in the presence of oxygen, the tissue-localized nontoxic sensitizer generates cytotoxic reactive oxygen species, and as a result, the selective destruction of a targeted tumor may be achieved.
