Also written as: SBRT — Stereotactic Body Radiation Therapy

Stereotactic Body Radiation Therapy, a precise high-dose radiation technique for small tumors, also called SABR.

Full Definition

SBRT delivers ablative doses of radiation in 1-5 fractions using advanced imaging and motion management to target tumors with millimeter precision. In thoracic oncology, SBRT is the standard treatment for medically inoperable early-stage lung cancer and selected oligometastatic lesions. The technique requires specialized equipment, immobilization, and real-time tumor tracking to minimize damage to surrounding healthy tissue while maximizing tumor control.

Usage

Usage note: SBRT and SABR are interchangeable terms. Always capitalize when abbreviated.
