What does SIRT stand for?

SIRT stands for Selective Internal Radiation Therapy. This term is used in the context of treating certain types of cancers, particularly liver tumors. SIRT involves the targeted delivery of radioactive microspheres directly into the blood vessels that feed the tumor, allowing for a high concentration of radiation to be delivered to the cancer cells while minimizing exposure to surrounding healthy tissue.

This treatment is particularly beneficial for patients who are not candidates for surgery or for those who have advanced disease. By utilizing a selective approach, SIRT aims to control tumor growth and, in some cases, enhance the patient’s quality of life.

The other terms, while they may sound plausible, do not correctly represent the established terminology in interventional radiology or radiation therapy. They lack specificity or established recognition in medical literature, which reinforces that Selective Internal Radiation Therapy is the correct and recognized name for this therapeutic approach.
