摘要:
This invention relates to a neoadjuvant therapy for bladder cancer in bladder cancer patients who are scheduled for a cystectomy and methods of carrying out such a neoadjuvant therapy. In particular the invention relates to a composition comprising hexyl 5-ALA ester (HAL) or a pharmaceutically acceptable salt thereof for use in a neoadjuvant therapy for bladder cancer in a bladder cancer patient who is scheduled for a cystectomy, the therapy comprises instilling said composition into the bladder of said patient and exposing the inside of said bladder to light.

It is intended to provide a therapeutic and/or diagnostic agent that can be used in photodynamic therapy (PDT) or photodynamic diagnosis (PDD) capable of utilizing infrared-spectrum light such as near-infrared light (NIR), infrared light, or far-infrared light, which attains a deep body penetration. The present invention provides a photodynamic therapeutic or diagnostic agent or a photodynamic therapeutic or diagnostic kit for cancer or infectious disease, comprising: a particle (e.g., a lanthanide particle) that emits upconversion luminescence by infrared-spectrum light such as near-infrared light having a wavelength of 0.7 µm to 2.5 µm; and a photosensitizer (e.g., porphyrin) or a 5-aminolevulinic acid group.
摘要:
Products, compositions, systems, and methods for modifying a target structure which mediates or is associated with a biological activity, including treatment of conditions, disorders, or diseases mediated by or associated with a target structure, such as a virus, cell, subcellular structure or extracellular structure. The methods may be performed in situ in a non-invasive manner by placing a nanoparticle having a metallic shell on at least a fraction of a surface in a vicinity of a target structure in a subject and applying an initiation energy to a subject thus producing an effect on or change to the target structure directly or via a modulation agent. The nanoparticle is configured, upon exposure to a first wavelength λ1, to generate a second wavelength λ2 of radiation having a higher energy than the first wavelength λ1. The methods may further be performed by application of an initiation energy to a subject in situ to activate a pharmaceutical agent directly or via an energy modulation agent, optionally in the presence of one or more plasmonics active agents, thus producing an effect on or change to the target structure. Kits containing products or compositions formulated or configured and systems for use in practicing these methods.

The invention is related to biomedicine in particular to diagnostics of oncological pathology conditioned tissue fluids. Neoplastic process often causes discharge of tissue liquids and their subsequent accumulation in various cavities of a body, most often in pleura and peritoneum. Treatment of patients, suffering from accumulation of tissue liquids caused by neoplastic process, is substantially different from treatment of cases of accumulation of tissue liquids caused by other conditions. Therefore for clinicians it is crucial to perform accurate and timely diagnostics of tissue liquids caused by pleural malignant ascites and other neoplastic pathologies. This invention provides a diagnostic system, comprising puncturing of an adequate volume of liquid accumulated in a tissue, when patient undergoing said test, prior to puncturing of said tissue liquid, with intent for treatment and/or diagnostics is administered with an adequate photosensitizer or its precursor, illuminating collected tissue liquid with a light (violet) having certain wavelength, whereat a color and intensity of the glow of said liquid is assessed visually or by spectrophotometric methods. Derivatives of hematoporphyrine, such as photofrin, photohem, photosan, which are illuminated with 400 - 405 nm wavelengths light, are used in the invention; the raspberry-color glow of a test liquid is assessed visually or by using a spectrophotometer.
