MRIdian radiotherapy for kidney cancer

The UK’s first MRIdian MR linac at our centre in Oxford offers new possibilities for safe and effective treatment of kidney cancers

MRIdian stereotactic ablative radiotherapy

At GenesisCare, we provide specialist cancer care to thousands of people worldwide. We offer cutting-edge, innovative cancer treatments that are clinically proven to be safe and effective.  

Stereotactic ablative radiotherapy (SABR) is a highly targeted radiation treatment that can be used to destroy tumours in just a few clinic visits. MRIdian is the latest type of radiotherapy machine capable of providing SABR which can see and adjust for every movement during treatment using magnetic resonance imaging (MRI). This makes MR guided SABR a very safe and precise way to treat tumours of the kidney. This ground-breaking new treatment is now available at GenesisCare.  

The MRIdian is one of the first of its kind in the world. It combines a powerful radiotherapy machine (called a linear accelerator or linac) with MRI technology to produce live, detailed images of your internal organs and tissues during treatment.  

Tumours of the kidney can be difficult to target with other types of radiotherapy machine because they move during normal breathing and are near other unaffected organs. MRIdian MRI-guided radiotherapy is able to turn on the radiation beam only when the tumour is positioned precisely in the treatment window and turn off the beam in an instant if the tumour moves even by a fraction – helping to protect normal tissue from unnecessary radiation exposure. No other radiotherapy technology in the UK is currently able to achieve this. 

GenesisCare is an expert provider of SABR treatments and has invested in the MRIdian to offer our patients access to this latest, world-class treatment here in the UK. 

Benefits of the MRIdian

Real-time MRI means the MRIdian can show the exact position and shape of the tumour during treatment and therefore precisely target radiation at the tumour 

The MRIdian is the only MR linac to have automated beam control, so if your tumour moves slightly, your treatment will automatically pause until it comes back into position 

Increased accuracy means the radiation beam is less likely to damage normal tissue and nearby organs (such as the other kidney, bowel or spinal cord) when compared with conventional radiotherapySide effects occur when healthy tissue is damaged 

Conventional radiotherapy is less often used for renal cancershowever, when it is used, it requires several weeks of daily therapy. The radiation with the MRIdian is much more focused and accurate so you’ll need far fewer treatments, ranging from a single treatment to five treatments

The MRIdian for kidney cancer treatment

Renal cell carcinoma (RCC) is a cancer of the kidney affecting people of all ages. Surgery has long been the main form of treatment for an RCC localised to your kidneys – this means where the cancer has not spread elsewhere in your body. You may however have other health problems, such as cardiovascular problems or obesity, meaning surgery is not advisable or not possible, or you may simply prefer to not have surgery. 

 

Less invasive RCC treatments are available, such as cryotherapy, ablation or embolisation, however some are limited to the treatment of smaller tumours only and they still require you to have a general anaesthetic. Tumours placed centrally in the kidney usually require the whole kidney to be removed. With SABR, only the tumour is targeted, with the remaining kidney spared, therefore retaining function while providing an excellent treatment. 

The MRIdian at GenesisCare in Oxford – the only one in the UK – is designed to safely treat such cancers without the need for a general anaesthetic or surgery. MRIdian treatment is also suitable for patients on blood-thinning medication (anticoagulants) without the need to stop or alter your treatment.  

 

What are the side effects of kidney radiotherapy with the MRIdian?

 

Your GenesisCare consultant will discuss with you what side effects you’re likely to experience, which may include mild tiredness, nausea which responds well to anti-sickness medications, and a reduction in renal function. It’s important that you attend your follow-up appointments so we can identify and treat any problems as soon as possible. Your consultant and radiographers can also provide advice about things you can try to help, and no question is too small if you have any queries or concerns.

We know that living with cancer can be challenging. That’s why you’ll also be offered support through life-changing therapies, such as psychological support and wellbeing therapies. These are provided to all patients at no extra cost to you or your insurer, to help you manage the side effects of treatment and symptoms of cancer.

SABR for kidney cancer

Range of tumour sizes treated

SABR is suitable for larger kidney tumours that cannot otherwise be treated with non-operative treatment options like ablation or embolisation

No invasive procedures

SABR is completely non-surgical, delivered in only a few outpatient visits, with no tattoos and no procedure to place gold markers which may be required for SABR on other machines

Reduced risk of kidney damage

Compared to surgery, it has been shown that SABR is able to treat cancer effectively without the risk of significant kidney damage or reducing kidney function

Clinical studies

Renal cell carcinomas (RCCs) have traditionally been difficult to treat with radiotherapy because they were considered to be resistant to conventional doses of radiation. However, SABR is delivered at very precise target areas using a much higher dose than conventional radiotherapy, meaning it can more effectively destroy tumour cellsStudies show excellent results with cancer control for SABR in the kidney. SABR for RCC has been shown to be effective and well-tolerated with manageable side effects. It preserves kidney function with outcomes that are similar to other treatments. [1] 

The kidneys are close to other tissues and organs which are sensitive to radiation injury, and the high doses of SABR makes it all the more important to protect these tissues. Delivering SABR using MRI-guided technology such as the MRIdian can help to protect these tissues and limit side effects and risks.
