What Is SABR?
Stereotactic Ablative Radiotherapy (SABR) is a precise way of targeting certain cancers with very good outcomes. It is mostly used for patients with localized tumours or , by other hand, with metastases. Primary tumours amenable with SABR as radical treatment are lung cancerand prostate. Sites of metastases amenable for SABR are: lung, liver, bone, spine, lymph nodes and adrenal glands. SABR in brain metastases is called SRS (Stereotactic Radiosurgery)
How Does SABR Work?
SABR works by using high dosage rays to target malignant cells and aims to killt the cancer cells, ideally destroying it completely. SABR uses small, thin direct beams of radiation to hit the tumour from different angles, allowing the tumour to get the maximum high dose of radiation whilst protecting the healthy tissues and cells from radiation. By using such a targeted form of radiation therapy, it drastically reduces the risk of damaging the healthy tissue surrounding the tumour. Usually given over a period of one or two weeks, the patient will receive 1, 3, 5 or 8 fractions of treatment alternate days tipically. SABR can be given with fewer treatments than standardradiotherapy, due to the higher doses per fraction used.
What Are The Side Effects of SABR?
Although SABR has been designed to minimise side effects, there is still a possibility that thepatient may experience some side effects during and after treatment. The general side effects of SABR can include tiredness, dry, blotchy and itchy skin and the area that has been treated feeling swollen, bruised or tender. Dependant on the area being treated, the patient may also experience nausea, chest pain, headaches and problems when eating or digesting food.It is worth noting that the majority of side effects do not occur immediately. Symptoms may develop weeks or even months after treatment has ended. Your doctor will advise you if there is anything to worry about.
