What does ablative treatment mean?
In radiotherapy, this usually describes a high biological dose delivered accurately in a small number of sessions to achieve strong local tumour control. SBRT and SABR refer to stereotactic body radiotherapy. Stereotactic radiosurgery (SRS) uses related principles for targets in the brain and sometimes spine, without surgical incisions.
When can it be considered?
Selected localised tumours and well-defined metastases in places such as lung, liver or spine may be candidates. Size, motion, prior radiation and nearby sensitive organs affect suitability.
What is oligometastatic disease?
It describes a limited number of metastatic sites. In some circumstances, treating individual sites may offer additional disease control, but the term does not make ablative treatment automatically necessary or curative.
Why is planning so detailed?
High-quality imaging, motion management and positioning checks are essential. Nearby spinal cord, bowel, lungs or other organs may limit the dose or change the approach.
Is one session always best?
No. One or several sessions may be used. The aim is to balance local control, safety and the patient’s needs.
Possible side effects
These depend strongly on the site; fatigue and transient discomfort may occur, and important late risks remain possible. Precision does not eliminate risk.
