SBRT for lung cancer

SBRT for lung cancer

Preserving healthy tissue is important for many lung cancer patients, who may be struggling with other conditions like emphysema.

With sterotactic body radiation, our lung cancer team delivers:

  • Higher radiation doses to tumors that would not be possible with other radiation therapies.
  • Less damage to healthy lung tissue.
  • A fewer number of treatments than conventional radiation therapy

SBRT for lung cancer may offer a treatment option to patients who are not candidates for surgery, because of tumor size or location, emphysema or heart disease.

What is stereotactic body radiation therapy (SBRT)?

Stereotactic body radiation therapy (SBRT) uses advanced imaging techniques to deliver a targeted radiation dose to a tumor. The radiation is focused on the tumor with millimeter precision. The result is that less healthy tissue gets damaged by radiation. Preserving healthy tissue is important for cancer patients whose tumors are near or in essential organs.

How it works

Before treatment, markers are placed around the tumor. SBRT uses an advanced coordinate system to precisely locate the tumor to ensure proper placement of the tracking devices. During treatment, we deliver concentrated, highly focused radiation treatment. The custom mapping provided by the coordinate system plans the radiation to account for a patient's anatomy, breathing and organ motion.

Throughout the treatment, the intensity and direction of the beams are constantly modulated to target the tumor and spare healthy tissue. The beams are also adjusted for any movement from breathing or digestion.

SBRT may be used to deliver a single high dose of radiation, or several fractionated radiation doses (usually up to five treatments over a period of days).
