What is radioisotope therapy
The treatment with radioactive isotope is an effective treatment method for metastatic prostate cancer. Often radioisotope therapy is used when treatment options with other approved methods have been exhausted, have proven ineffective, or the patient cannot tolerate them. The aim of radioisotope therapy is to reduce tumor volume, the rate of metastatic dissemination and other symptoms of the disease.
What is the effect of radioisotope therapy?
The amount of prostate-specific membrane antigen (PSMA) increases significantly in prostate cancer cells, and if the prostate cancer has spread to other parts of the body, then PSMA expression will be detectable there, too. Radioisotope in combination with a special peptide binds to PSMA receptors located on cancer cells, and radioactive isotope destroys these cancer cells.
