SABR for kidney cancer in the UK

A non-surgical SABR treatment for primary and secondary kidney Cancer

If you have been diagnosed with kidney cancer, surgery may not always be the safest or most suitable option. The decision often depends on the size and position of the tumour, your kidney function, your general health and whether other treatments are already controlling the wider disease.

SABR radiotherapy offers a highly targeted, non-surgical treatment approach for carefully selected patients. It is planned around the exact tumour location, with the aim of treating the cancer in the kidney while reducing dose to the surrounding healthy kidney and nearby organs.

local and Metastatic cases

A precise treatment option for selected primary kidney tumours and carefully assessed kidney metastases.

1 to 5 treatment sessions

A short course of SABR radiotherapy, delivered in carefully planned outpatient sessions.

No surgery required

A non-surgical outpatient treatment designed to target the tumour precisely, without hospital admission.

WHAT IS kidney CANCER?

Kidney cancer explained: diagnosis, types and treatment

Kidney cancer begins when abnormal cells in the kidney grow into a tumour. The most common type in adults is renal cell carcinoma.

Some tumours are contained within the kidney, while others may involve nearby structures or, less commonly, the kidney may contain a secondary tumour from a cancer that began elsewhere. These situations require different treatment planning.

Detailed scans, pathology and a review of kidney function help the clinical team build a clear picture before recommending the most appropriate next step.

Common Symptoms Of Kidney Cancer

Blood in the urine, even if it only happens once
Persistent pain in the side or lower back, below the ribs
A lump or swelling in the side, back or abdomen
Ongoing tiredness that does not improve with rest
Unexplained weight loss
Loss of appetite
Repeated high temperatures or night sweats
A general feeling of being unwell

Many symptoms linked with kidney cancer can also be caused by less serious conditions. Still, if you notice any unusual or persistent changes, particularly blood in your urine, it is important to contact your doctor.

Types Of Primary Kidney Cancer

Clear cell renal cell carcinoma

The most common type of kidney cancer in adults. It starts in cells lining the kidney’s small filtering tubes, which remove waste from the blood.

Papillary renal cell carcinoma

The second most common kidney cancer. It begins in the small filtering tubes of the kidney and may develop in one or more places within the organ.

Chromophobe renal cell carcinoma

A less common type of kidney cancer. It starts in specialised kidney cells that help collect urine before it passes from the kidney to the bladder.

Types Of Secondary Kidney Cancer

A secondary kidney tumour, also called a kidney metastasis, occurs when cancer that began elsewhere in the body spreads to the kidney. Kidney metastases are uncommon and need careful assessment alongside the original cancer, scan results and any other areas of disease.

kidney CANCER TREATMENT OPTIONS

Your treatment options for primary and Metastatic kidney tumours

Here is no one treatment route for cancer in the kidney. Decisions are guided by the type and location of the tumour, kidney function, your general health and, for secondary tumours, the wider pattern of disease.

Stereotactic Radiotherapy (SABR)

SABR is a non-surgical, targeted radiotherapy treatment for selected kidney tumours. It may be considered when surgery is not suitable, or for a carefully assessed kidney metastasis as part of a wider treatment plan.

Partial Nephrectomy

A partial nephrectomy removes the tumour while preserving as much healthy kidney tissue as possible. It is the preferred surgical approach for many localised kidney cancers, particularly smaller tumours, when it can be performed safely.

Radical Nephrectomy

A radical nephrectomy removes the whole affected kidney. It may be recommended when the tumour is too large, too complex or too centrally positioned for a partial nephrectomy to be appropriate.

Cryotherapy and Heat Ablation

Cryotherapy freezes tumour cells, while radiofrequency or microwave ablation uses heat to destroy them. These needle-based treatments may be options for selected small kidney tumours, particularly for people who are not fit for surgery.

Systemic Treatment

For cancer that has spread, systemic treatment works throughout the body. This may include immunotherapy or targeted therapy. For kidney metastases, treatment is guided by the original cancer.

Renal Artery Embolisation

Renal artery embolisation blocks the blood supply to a kidney tumour. It is not a curative treatment, but may be used to help manage symptoms when surgery is not appropriate.

WHAT IS SABR TREATMENT FOR kidney CANCER

A non-surgical treatment for selected kidney tumours

SABR is a form of precision radiotherapy designed to target a tumour in the kidney without an operation. Before treatment begins, the team uses detailed scans to map the tumour and assess the surrounding kidney and organs. This allows the dose to be shaped as accurately as possible.

For primary kidney cancer, SABR can be an option when treatment is needed but surgery is not appropriate. Where cancer has spread to the kidney from another site, it may be considered as part of an individual plan for limited disease.

Kidney SABR may be delivered using one of the following:

THE BENEFITS OF SABR FOR kidney CANCER

Why Patients Choose SABR for Kidney Cancer Treatment

For selected patients, SABR can offer a different treatment experience from surgery or a longer course of conventional radiotherapy. The potential advantages depend on the tumour’s size and position, how well the kidneys are working, your general health and whether other cancer treatment is underway.

Not every benefit will apply to every situation. Your specialist team will explain what SABR could realistically offer in your case, alongside the possible risks, limitations and alternative treatment options.

SABR is an outpatient procedure. You attend the radiotherapy centre for treatment and normally leave on the same day.

The radiation is delivered externally. No operation, general anaesthetic or surgical recovery period is required.

Depending on the tumour and treatment plan, kidney SABR may be delivered in a single session or over several visits.

For selected patients, SABR may be considered when an operation is unsuitable because of health, kidney function or tumour position.

Planning takes account of the tumour’s position within the kidney and its relationship to nearby bowel and healthy kidney tissue.

Your treatment plan is shaped around the tumour’s size and location, kidney function, and the surrounding organs, rather than a fixed approach.

Is SABR Right for You

When SABR May Be Considered for Kidney Cancer Treatment

The decision to use SABR is based on the detail of your diagnosis, not one factor alone. The situations below are examples of when a specialist review may be appropriate.

SABR is most often considered for a defined primary kidney tumour that has not spread widely elsewhere in the body.

Age, frailty or other health conditions can make an operation less suitable. SABR may offer a non-surgical local treatment option.

With one functioning kidney or impaired kidney function, preserving as much healthy kidney tissue as possible is an important part of your assessment.

The tumour’s size or position may make kidney-sparing surgery technically difficult. SABR can be reviewed alongside other local treatments.

Some kidney tumours cannot be safely treated with freezing or heat ablation. Your team can assess whether targeted radiotherapy could be suitable too.

For some patients, avoiding surgery and general anaesthetic is an important consideration. SABR may be discussed if it is clinically suitable for the tumour.

SIDE EFFECTS OF kidney SABR

What Are the Possible Side Effects of SABR Treatment for Kidney Cancer?

Most people complete kidney SABR without major side effects, although every treatment carries some risk. The likely effects depend on the location of the tumour within the kidney, surrounding organs and your kidney function before treatment, particularly if you have one functioning kidney. Before treatment, your team will explain what to look out for and how any side effects will be monitored:

Short-Term Effects

Longer-Term Effects

Serious complications are uncommon but need individual discussion before treatment.

Getting started

How Your Kidney SABR Treatment Journey Unfolds, Step by Step

Whatever brought you to this point, a fresh diagnosis, advice that surgery isn’t suitable, or cancer that has spread, reaching a decision about kidney SABR follows a clear and consistent process. Here is how that process unfolds.

Initial Enquiry

Get in touch by phone, email or the form on this page, no referral needed. Our team will reply within one working day to discuss your case and arrange a consultation.

Clinical Assessment

A specialist reviews your scans, kidney function and treatment history to judge whether SABR is suitable, or whether another approach would be safer.

Scan And Case Review

Your scans are reviewed to see whether the tumour started in the kidney or has spread there, and whether its size and position can be treated safely.

Personalised Treatment Plan

If treatment goes ahead, the plan is built around tumour position, kidney function, nearby bowel or other organs, and any earlier surgery, ablation or radiotherapy.

Starting Treatment

Treatment is planned as a short outpatient course. For kidney tumours, session number varies according to tumour size, location and kidney function.

Monitoring Over Time

Response is checked over time using follow-up scans, kidney function tests and symptoms, with clear guidance on what the results mean and next steps.

Can SABR be used if I only have one kidney?

Yes, in selected cases, though the assessment is more detailed. Because there is no second kidney to compensate, treatment planning pays particularly close attention to preserving as much healthy kidney tissue as possible, and follow-up monitoring of kidney function is closer.

Will I need to stay on dialysis or start it because of treatment?

Most patients do not need dialysis after kidney SABR. It is uncommon and occurs mainly in people who already had reduced kidney function before treatment, rather than being a typical result of SABR itself.

Can SABR be repeated if a new kidney tumour develops later?

In some cases, yes. Whether repeat treatment is possible depends on the location of the new tumour relative to previously treated tissue and how much healthy kidney function remains.

Will I need to change my diet or medication before or after treatment?

Most patients continue their normal medications and diet. If you take blood-thinning medication or have other kidney-related prescriptions, this will be reviewed individually as part of your assessment.

How soon can treatment start after my consultation?

Once your scans and case have been reviewed, planning typically takes a number of days before treatment begins, as a tailored radiation plan needs to be built around your specific tumour and anatomy.
