  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   Anti-tumor efficacy was similar between intratumoral and IV administration; however, smaller doses of Photofrin were Continue reading →Customer case University of Rochester belongs among the nation’s top research universities. Research at the Baran lab focuses on anti-microbial PDT and optical image processing. The aim is to develop methods for utilizing quantitative information from CT, MR and PET imaging for PDT treatment planning as well as in the search of new biomarkers and therapeutic targets.

Motivation of the study In photodynamic therapy (PDT), systemically administered photosensitizer is activated within the tumor using focused near-infrared light, typically a laser with a wavelength matching the absorption peak of the photosensitizer. Several photosensitizers have been clinically approved for the treatment of different cancers; however, their accumulation is non-tumor exclusive which exposes healthy tissues to side effects like daylight-induced phototoxicity. A promising strategy to improve tumor selectivity is to couple photosensitizer to a tumor-targeting agent that binds to a specific antigen expressed on the Continue reading →Customer case Research by: Duke University, founded in 1924, is one of the leading and wealthiest private research universities in the USA. The most notable Duke alumni is President Richard Nixon. Research at Duke University has been awarded with several Nobel prizes in recent years for groundbreaking discoveries in biochemistry and medicine, such as G-protein coupled receptors, DNA mismatch repair, and cellular regulation of hypoxia.
