Theranostics – the trend of medicine

Tomsk Polytechnic University newspaper "For Cadres" 

Theranostics is the global trend of medicine of the future. The term has appeared relatively recently in modern science. Theranostics combines the entire cycle of medical services: from early diagnosis of diseases to therapy and subsequent monitoring of treatment. 

Creation of new, globally competitive radiopharmaceuticals, devices and methods of medical radiology for the diagnosis and therapy of oncological and cardiovascular diseases, world-class educational programs in the field of medical engineering to train world-class specialists for domestic and foreign medical centers. 

These are the goals of the TPU project "Innovative methods of theranostics. INNOMET». It is implemented on the basis of the TPU Institute of Physics and Technology. This project is part of a unique cluster "Medical Engineering", created as part of the Program to improve the competitiveness of Tomsk Polytechnic University among the world's leading scientific and educational centers.

Improving the quality and life expectancy of the world's population is a key task of modern science. And success can be achieved only through inter–network interaction, because theranostics is a complex, integral science. This is the way the developers of the project "Innovative methods of theranostics. INNOMET».

Project idea

Development of resource-saving technologies to improve the quality and life expectancy of the world's population. The goal is to create highly effective drugs, equipment and radiation technologies for theranostics (diagnostics and therapy) of oncological diseases.

Priority directions of development of cancer theranostics in the world
  • Monoclonal antibodies for targeted drug delivery. 
  • Nanocomplexes (iron oxide, nanorubins and nanophosphores, silicon) for imaging, chemotherapy, thermal effects on cancer cells initiated by alternating magnetic fields, ultrasound, etc. 
  • Targeted diagnostic and therapeutic tandems based on radioactive isotopes.
Publications in publications indexed by Web of Science and Scopus: 120 articles (84 -2014, 36 — I half of 2015).

Project objectives
