Russia has developed a new method of "nuclear" treatment of "slow" cancer
Specialists of the National Research Center "Kurchatov Institute" have developed a new approach to the targeted treatment of so-called neuroendocrine malignant tumors based on nuclear medicine methods, the press service of the Kurchatov Institute reported.
Neuroendocrine tumors arise from nerve cells that produce hormonal substances. Most often, such cells are located in the gastrointestinal tract, and develop relatively slowly. The Kurchatov Institute proposed using the radioactive isotope lead-212 (Pb-212) as a basis for combating such tumors and bone metastases. This isotope is considered as a promising source of alpha particles, which have a very short run in the tissue and destroy cancer cells more efficiently.
The essence of the new technique is that the Pb-212 isotope "attaches" to the biological molecule octreotide, which delivers the radionuclide to the cancer cell. The new approach allows you to act directly on the tumor without exposing healthy cells to radiation, the report says.
Work in the field of nuclear medicine is one of the main activities of the Kurchatov Institute. Its scientists are developing nuclear technologies for medical purposes, are engaged in the production of new organic substances that are the active principle of radiopharmaceuticals.
