Stereotactic Radiotherapy (SRT)

Stereotactic radiotherapy (SRT) is a new lung cancer treatment.  SRT lung cancer treatment, sometimes called stereotactic surgery or radiosurgery, is not surgery at all.   It is actually a type of radiation therapy that uses a very high dose of radiation delivered very accurately to tumors in the body.

SRT as an alternative to lung cancer surgery provides another option to elderly patients, patients with severe lung disease, patients with severe heart disease, and other patients with poor health who might not be considered good candidates for traditional lung cancer surgery.

SRT is an out-patient procedure conducted in the radiation oncology department. The procedure is painless and patients can continue their daily activities without difficulty. STR uses special positioning procedures and radiology techniques so that a higher dose of radiation can be delivered to the tumor, and a smaller part of the healthy lung is exposed.

SRT is a promising new technology for stage one non-small cell lung cancer. Lung cancer surgery remains the gold standard. SRT is usually used for patients who could not tolerate lung cancer surgery or would rather not have the lung cancer surgery.
