What is Lung Stereotactic Ablative Radiosurgery?
Lung Stereotactic Ablative Radiosurgery (SABR) is a non-invasive, highly targeted form of radiation treatment that is recommended in international cancer guidelines as an alternative to surgery in early stage lung cancers for selected patient groups. SABR has been proven in studies to confer excellent survival rates comparable to surgery and is an increasingly important option in early stage lung cancer treatment.
* The NCCN guidelines on NSCLC is written by 30 leading cancer centres in the U.S and is regarded as the gold standard internationally
Lung SABR is also commonly used in stage 4 cancers to target tumors that have spread to the lung, and to prevent or relief symptoms. Often, it is combined with immunotherapy to achieve a synergistic effect. Unlike surgery or other invasive procedures, SABR does not cause disruption to the continued use of chemotherapy or targeted therapy in these patients.
SABR works by using technologically advanced machines to deliver extremely focused beams carrying high doses of radiation directly to the tumour to destroy it. With SABR, an entire treatment course can be completed in three to five outpatient sessions over two weeks, with no surgical or anaesthetic risk.

Understanding the difference between Surgery and Radiosurgery
Right-sided lung tumor treated with SABR with complete disappearance of tumor 6 months later
Surgery involves physically cutting through tissue and bone to reach the tumor so as to remove it from the body.
Radiosurgery does not involve any cutting at all. The name was given because after destroying the tumor with high doses of focused radiation, the body automatically removes the dead cells, and the cure rate is as if surgery was done
It is completely painless, bloodless and is done as an outpatient procedure.
Patient does not need to undergo open surgery and does not suffer from operation risks
Using advanced technology, radiosurgery precisely targets tumors painlessly, without the need for open surgery
