Lung cancer
Early-stage lung cancers in patients unsuitable for surgery. Also oligometastatic lung disease where ablating each lesion may extend disease-free intervals.
Stereotactic Body Radiation Therapy — an ablative dose delivered to a precisely defined tumour target in just 3–5 sessions. Comparable cancer-control to surgery for many indications, without an incision, hospital stay, or recovery period.
SBRT delivers a very high dose of radiation to a precisely defined tumour, in just 3–5 sessions instead of the 25–30 sessions of conventional radiotherapy. Each beam is sculpted to the exact 3D shape of the tumour, and image-guidance ensures the patient is positioned to within a millimetre of the planned position before every session.
What this means in practice: the dose is concentrated where it needs to be — and falls off sharply just outside the target. Surrounding healthy tissue receives a tiny fraction of the dose. That's why SBRT achieves cancer-control rates comparable to surgery for many indications, while sparing patients from anaesthesia, incisions, and weeks of recovery.
SBRT is a treatment that depends on technology, planning, and disciplined delivery — three things AARO has invested in refining at the Centre for Stereotactic Radiosurgery.
SBRT is suited to specific clinical situations. Where it applies, it offers a different option from surgery or conventional radiation — fewer sessions, a focused dose, shorter recovery. These are the most common indications.
Early-stage lung cancers in patients unsuitable for surgery. Also oligometastatic lung disease where ablating each lesion may extend disease-free intervals.
Hepatocellular carcinoma not suitable for surgical resection or RFA, and limited liver metastases (1–3 lesions). SBRT preserves liver function while ablating disease.
Primary spine tumours, vertebral metastases, and re-irradiation cases needing high-precision boost. SBRT delivers tumour dose while keeping the spinal cord under tolerance.
Low- and intermediate-risk localised prostate cancer in 5 sessions — comparable cancer-control to 28-session conventional radiation, with fewer visits and equivalent toxicity profiles.
Patients with 1–5 distant metastases — from breast, prostate, lung, colorectal or other primaries — where ablating each lesion may delay systemic progression and extend disease-free survival.
Recurrent disease in a previously-irradiated area. SBRT's sharp dose fall-off makes re-treatment possible where conventional radiation could not safely be repeated.
From first planning scan to last fraction, an SBRT course at AARO follows the same disciplined pathway. Hours of preparation per minute of treatment.
A high-resolution CT scan in the treatment position. Your oncologist contours the tumour and surrounding organs-at-risk on every slice.
Medical physicists and therapists optimise dose distribution against constraints. The plan is independently checked before approval.
Before every fraction, on-board imaging confirms your position to within a millimetre. Positioning lasers and the precision treatment couch correct for any drift.
Each fraction takes 15–30 minutes on the couch. You'll feel nothing as the radiation is delivered. 3–5 sessions over 1–2 weeks completes the course.
Most patients are surprised by how uneventful SBRT feels. You'll arrive, change into a gown, and lie on the precision treatment couch. Therapists position you using the same setup from your planning scan, take a verification image, and step out. The treatment itself takes around 5–10 minutes — you won't feel or see the radiation.
Side effects depend on what we're treating. Most are short-term and mild — fatigue, localised skin changes, or specific organ-related effects (such as oesophagitis for thoracic SBRT). They resolve within weeks of completing treatment.
You can drive yourself home, return to work, exercise, and travel. There's no anaesthesia, no incision, no overnight stay. For prostate SBRT we use SpaceOAR; for left-sided breast we use DIBH; for lung SBRT we monitor breathing motion. Each technique exists to minimise the dose to healthy tissue.
SBRT is generally covered under Medisave and MediShield Life for approved indications, and under major Integrated Shield Plans. Out-of-pocket costs vary based on case complexity and your specific plan.
We provide a written cost estimate at consultation, before any treatment begins. If you'd like our care coordinator to verify coverage with your insurer in advance, just ask.
Each AARO specialist delivers SBRT within their sub-specialty focus. Dr Daniel Tan leads brain, spine and oligometastatic-disease cases. Dr David Tan and Dr Jonathan Teh handle prostate and pelvic SBRT. Dr Michelle Tseng covers thoracic SBRT.
Book a 45–60 minute specialist consultation. We'll review your imaging, explain whether SBRT applies to your case, and answer your questions.
