[Rationale for development of new domestic appliances theranostic apparatus for photodynamic therapy and fluorescent diagnostics in oncology].

The review discusses the relevance of creating original theranostic apparatus for photodynamic therapy (PDT) and fluorescent diagnostics (FD) to fulfill the needs and meet the objectives of oncology field specialists. Increased accuracy of diagnosis and improvement of treatment outcomes is possible only in case of the right combination of photosensitizer (PS) with the light source with a wavelength at which the maximum absorption of the PS is observed. The absence of medical devices combining functions of PDT and FD makes the development of the domestic theranostic apparatus for oncology an extremely important task.
