SBRT (stereotactic body RT) or SABR (stereotactic ablative body radiotherapy)
SBRT or SABR allow high-precision RT delivery to extracranial areas using repeated imaging before and during treatment. Accuracy is so high that curative doses can be delivered in 5e10 fractions. Excellent outcomes have been shown in stage 1 non-small cell lung cancer and this has now become a standard of care.15 Studies are also being conducted into pancreas tumours, prostate cancer and liver metastases.
