Light penetration depth in brain with different photosensitizers

  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

Development of heat shock protein 90-targeted PDT for inflammatory breast cancer

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… READ MORE
