There is no excerpt because this is a protected post.Introduction to fluorescence imaging Fluorescence is a phenomenon where substance that has absorbed certain wavelength of light emits it back at another wavelength. These substances are called fluorophores or fluorescent dyes. The emitted light has a longer wavelength than the absorbed one since some energy of the photon is lost in the process. The difference in wavelengths between absorbed and emitted light, called Stokes shift, allows very low background for fluorescence detection by separating it from the excitation light. The process of fluorescence generation is

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 substantial portion of the tumor, up to 60%, was above 60 ⁰C. Above figures

It is also the place where photodynamic therapy (PDT) was developed in the late 1970s by Thomas Dougherty. The PDT center at Roswell Park is a leader in the use of photodynamic therapy for treating different cancers. Research work includes treatment planning and light dosimetry for interstitial and intraoperative PDT to improve the quality of life and survival of cancer patients

Motivation for the study The motivation was to study if photoimmunotherapy could enhance anti-tumor immunity when combined with immune checkpoint inhibition. CD44-targeted photoimmunotherapy was applied against poorly immunogenic, “cold” tumor and antitumor effect was studied alone and in combination with anti-PD-1 immune checkpoint inhibition. Sensitization of this “cold” tumor to immune checkpoint inhibition after photoimmunotherapy would mean that the tumor has been converted into highly immunogenic, “hot” tumor infiltrated with killer T cells mainly responsible for eradicating the tumor. The formation of immunological antitumor memory

Results Tumor growth was significantly suppressed by photoimmunotherapy, compared to control or IgG without light activation. Tumor growth suppression, as well as overall survival after photoimmunotherapy, were significantly better with F(ab´)2 fragments than with full IgG. This efficacy improvement might be related to killer T cells, which were detected in much higher numbers after photoimmunotherapy with F(ab´)2 fragments and are key cells for the generation of efficient systemic antitumor immunity.

Motivation for the study Polyps are small growths on the inner lining of the colon or rectum, affecting around 1 in 4 people over the age of 50. Certain types of polyps may eventually become cancerous, and colon cancer prevention relies on colonoscopy using white light to detect and remove the polyps. However, small and flat polyps are difficult to detect and frequently missed with this technique. More precise methods to detect polyps before they progress to colorectal cancer are urgently needed.
