Introduction: Is there a Better Way to Detect Prostate Cancer Early?

Prostate cancer mainly affects men over the age of 50 and the risk increases with age. In the UK, it is estimated that 1 in 8 men will be diagnosed with prostate cancer in their lifetime. The UK has seen a steady increase in the incidence rates of prostate cancer over the past few decades, which can be attributed to increased awareness, improved diagnostic techniques, and an ageing population.

The Traditional Approach to Prostate Cancer Diagnosis

What are the Challenges Associated with Traditional Prostate Cancer Diagnosis Methods?

Several scanning methods are currently employed for the detection of prostate cancer, each with its own merits and limitations. In the video below, Dr Chris Steele discusses the basics of prostate cancer, what symptoms you should be aware of and how the traditional tests are carried out. But new research and methods give early indications that the MRI scan could offer a more reliable method of detecting cancers early.

 

PSA Test

The PSA (Prostate-Specific Antigen) test is a blood test that measures the level of PSA in the blood. It is usually the first step in the screening process for prostate cancer. A high level of PSA can indicate the presence of prostate cancer, although it can also be raised due to other non-cancerous conditions like prostatitis or an enlarged prostate.

Digital Rectal Examination (DRE)

A DRE is a physical examination where a doctor or nurse inserts a gloved, lubricated finger into the rectum to feel for any irregularities in the prostate gland. While this method can be uncomfortable, it is a quick and essential part of the initial assessment for prostate cancer.

MRI Scan

Multi-parametric MRI (mpMRI) scans are used to get detailed images of the prostate gland. This scan can help determine the location and size of the tumour and can help guide a biopsy if needed.

Biopsy

A biopsy is when a small sample of tissue is removed from the prostate and examined under a microscope for cancer cells. A targeted biopsy, guided by mpMRI images, is preferred as it increases the chances of detecting significant cancer while reducing the risk of over-diagnosis and over-treatment.

The Advent of Prostate MRI Scans

How are Prostate MRI Scans Transforming Prostate Cancer Diagnosis?

The Advent of Prostate MRI Scans heralds a significant advancement in the field of medical imaging and prostate cancer diagnosis. Prostate MRI scans, specifically multi-parametric MRI (mpMRI) scans, combine multiple MRI sequences to provide a comprehensive assessment of the prostate gland. This includes assessing the anatomy, cell density, and vascular characteristics of the prostate tissue.

Suspicious areas identified in the scan are then given a PI-RADS (Prostate Imaging – Reporting and Data System) score, which assesses the likelihood of clinically significant prostate cancer. A higher PI-RADS score indicates a higher likelihood of clinically significant cancer.

What are the Benefits of Prostate MRI Scans?

The benefits of Prostate MRI scans are manifold:

• They provide a non-invasive way to accurately identify and assess potential cancerous lesions in the prostate. This is crucial for early detection of clinically significant cancers that require treatment.
• Prostate MRI scans can guide targeted biopsies by pinpointing the exact location of the suspicious areas, thereby reducing the need for systematic biopsies which involve taking multiple tissue samples from different areas of the prostate.
• This targeted approach increases the accuracy of the biopsy and reduces the risk of complications.
• Prostate MRI scans aid in treatment planning by providing detailed information about the size and location of the tumour, as well as any potential spread to nearby tissues or lymph nodes. This information is critical for selecting the most appropriate treatment option and planning the surgical approach if necessary.

How do Prostate MRI Scans Work?

Multi-parametric Magnetic Resonance Imaging (mpMRI) is a type of magnetic resonance imaging (MRI) scan that combines multiple sequences or parameters to provide a more comprehensive assessment of the prostate gland. It is considered one of the most advanced imaging techniques available for the detection and assessment of prostate cancer.

What are the Components of the mpMRI scan?

The ‘multi-parametric’ in mpMRI refers to the combination of different MRI sequences used during the scan:

a. T1-Weighted Images: These images are useful for detecting areas of haemorrhage or calcification within the prostate gland.

b. T2-Weighted Images: These images provide detailed anatomical information about the prostate gland and its surrounding structures. T2-weighted images are particularly useful for determining the size and location of the tumour.

c. Diffusion-Weighted Images (DWI): These images assess the movement of water molecules within the tissues. Cancerous tissues typically restrict the movement of water molecules, which can be detected on DWI.

d. Dynamic Contrast-Enhanced (DCE) Images: These images assess the blood flow and vascular characteristics of the tissues. DCE involves the injection of a contrast agent, and a series of images are taken before, during, and after the injection to assess how quickly the contrast agent is taken up and washed out of the tissues.

What is the PI-RADS Scoring System Used?

The Prostate Imaging – Reporting and Data System (PI-RADS) is a standardised scoring system used to interpret and report the findings of an mpMRI scan. The PI-RADS score ranges from 1 to 5, with 1 being highly unlikely to be clinically significant cancer, and 5 being highly likely to be clinically significant cancer.

What are the Limitations of the mpMRI Scans?

• Availability: While the availability of mpMRI has increased in recent years, it is still not available in all healthcare facilities.
• Interpretation: The interpretation of mpMRI images requires specialised training and experience.
• Cost: mpMRI is more expensive than traditional TRUS guided biopsies. However, the benefits of improved detection and reduced unnecessary biopsies may offset the higher upfront cost.

 

 

What does the Prostate MRI Scan Involve?

1. Preparation:
   • You may be asked to change into a hospital gown and remove any metal objects, such as jewellery, glasses, or hearing aids, as they can interfere with the MRI machine.
   • You may be asked to fast for a certain period before the scan, although this is not always necessary. Check with the imaging facility for specific instructions.
   • An intravenous (IV) line may be inserted into your arm if a contrast agent is needed for the scan.
2. Positioning:
   • You will be asked to lie down on a flat, movable table that slides into the MRI machine.
   • You may be given earplugs or headphones to wear as the MRI machine can be noisy.
3. Scanning:
   • The table will slide into the MRI machine, and the radiographer will operate the machine from a separate room. You will be able to communicate with the radiographer through an intercom system.
   • The MRI machine will produce a series of loud knocking and thumping sounds during the scan. It is important to lie as still as possible during the scan to ensure clear images.
   • The mpMRI scan combines multiple MRI sequences, including T1-weighted, T2-weighted, diffusion-weighted, and dynamic contrast-enhanced images, to provide a comprehensive assessment of the prostate gland.
   • If a contrast agent is used, it will be injected into your IV line partway through the scan.
4. Completion:
   • Once the scan is complete, the table will slide out of the MRI machine, and the IV line will be removed if one was inserted.
   • You will be able to change back into your clothes and leave the imaging facility.

 

The entire procedure typically takes around 30 to 45 minutes, although the total time may vary based on the imaging facility and the specific sequences included in the scan.

The mpMRI scan is non-invasive and does not involve ionising radiation. It is generally considered safe and well-tolerated, although some people may experience claustrophobia in the MRI machine or have an allergic reaction to the contrast agent. If you have any concerns or have a history of allergic reactions, be sure to discuss them with your healthcare provider before the scan.

How Much Do Prostate MRI Scans Cost?

In the UK, the cost of Prostate MRI scans can vary significantly based on several factors, including the location, the provider, and whether you are going through the NHS or opting for private healthcare. On average, the cost of a private prostate MRI scan is in the region of £400 to £995.

1. NHS: If you are referred for a Prostate MRI scan by an NHS doctor, the cost of the scan will usually be covered by the NHS. However, there can be long waiting times, and not everyone may be eligible for a referral, as it often depends on your symptoms and risk factors.
2. Private Healthcare: If you choose to go private, the cost can vary significantly from one provider to another. On average, the cost of a Prostate MRI scan in a private clinic can range from £400 to £995. Some of the well-known private healthcare providers in the UK that offer Prostate MRI scans include:

• • Circle Health: One of the largest private hospital groups in the UK, with over 50 locations across England, Scotland, and Wales. MRI scans at Circle Health hospitals start at £473.
  • Nuffield Health: Another prominent network of private hospitals in the UK with more than 30 hospitals across the country. A guide price at Nuffield hospitals is £400 and includes pre-assessment and post discharge care.
  • Spire Healthcare: A leading independent hospital group in the UK with 39 private hospitals and 8 clinics across the country. A referral letter from a consultant or GP is required before booking any diagnostic investigation. Prices are On Application.
  • Vista Diagnostics: A specialised diagnostic imaging provider with locations in London and other parts of the UK. The cost of an mpMRI scan at Vista Health is £650. At Vista Health you can refer yourself for a prostate MRI scan and don’t need a GP referral.

 

It is important to note that the cost of the scan may not include the consultation fee of the specialist who reviews the results. Additionally, if the scan indicates that a biopsy is needed, this will incur additional costs. It is always advisable to check with the provider for a detailed breakdown of the costs and what is included.

Some private health insurance plans may cover the cost of prostate MRI scans and biopsies, but this can vary from one policy to another, so it is important to check with your insurance provider for specific details on coverage. Additionally, some providers may offer finance options to help spread the cost of a private MRI scan over a period of time.

Studies into the Efficacy of the Scans

Several studies have been conducted to evaluate the efficacy of different scanning methods for prostate cancer detection:

The PROMIS Trial:

The PROMIS (Prostate MRI Imaging Study) trial was a landmark study conducted in the UK that evaluated the accuracy of mpMRI in detecting clinically significant prostate cancer before a biopsy. The results of the trial, published in The Lancet in 2017, indicated that using mpMRI before a biopsy could reduce the number of unnecessary biopsies by 27% while increasing the detection of clinically significant cancers by 18%.

The PRECISION Trial:

The PRECISION (Prostate Evaluation for Clinically Important Disease: Sampling Using Image Guidance or Not?) trial in 2018 was an international study that compared the outcomes of men who had an mpMRI-guided biopsy to those who had a standard TRUS (Trans-rectal Ultrasound) guided biopsy. The study found that the mpMRI-guided biopsy detected more clinically significant cancers and fewer insignificant cancers compared to the TRUS-guided biopsy.

The REIMAGINE Study

The REIMAGINE study by UCL, UCLH, and King’s College London reveals that using MRI scans with PSA density can detect serious prostate cancers missed by PSA blood tests alone. Currently, men over 50 with symptoms or concerns undergo a PSA test, triggering further tests like biopsy if levels exceed 3ng/ml. Although this approach reduced mortality by 20%, it led to over-diagnosis and over-treatment of lower-risk cancers. However, using MRI as a first step for higher-risk men prevented unnecessary biopsies for one in four men.

The study, published in 2023, involved 303 men aged 50-75, and 48 (16%) had a positive MRI despite a median PSA density of 1.2 ng/ml, indicating potential cancer. 29 men (9.6%) required treatment, 15 having serious cancer and a PSA below 3ng/ml. Professor Caroline Moore emphasised that MRI could offer a more reliable early detection method with fewer ‘over-diagnoses’ of low-risk disease.

The study also found that black men, who are at double the risk of prostate cancer, responded at one-fifth the rate of white men to screening invitations, highlighting the need for strategies targeting black men in any national screening program.

The next step, the LIMIT trial, is in progress. It aims to recruit more black men and, if successful, will necessitate a national-level trial before standardising screening. Professor Mark Emberton noted the UK’s prostate cancer mortality rate is double that of countries like the US or Spain, due to lower testing levels. He expressed confidence that a national screening programme would significantly reduce the UK’s prostate cancer mortality rate, but much work is needed.

The study was supported by the National Institute for Health and Care Research UCLH Biomedical Research Centre, the MRC, and CRUK.

The Impact of Prostate MRI Scans on Patient Outcomes

Commenting on recent developments, Simon Grieveson, assistant director of research at Prostate Cancer UK, said:

” When a man’s prostate cancer is caught early, it’s very treatable. Sadly, more than 10,000 men each year are diagnosed too late, when their cancer has already spread.

He went on to say how prostate MRI scans have revolutionised the diagnosis of prostate cancer and looked forward to research into the wider use of these scans. The hope is that prostate MRI scans could form the basis of a national screening programme.

At present there is no national screening programme because the results of the PSA test are considered to be too unreliable. It is hoped that after further studies that the prostate MRI scan could be used for this screening and pick up serious cancers that may have been missed by the PSA test alone.

What is the Best Scan for Prostate Cancer?

Multi-parametric MRI (mpMRI) is currently considered the best imaging technique for the detection and assessment of prostate cancer. It combines multiple MRI sequences to provide a comprehensive assessment of the prostate gland and can help determine the location and size of the tumour, guide targeted biopsies, and aid in treatment planning.

The Prostate Imaging – Reporting and Data System (PI-RADS) is used to interpret and report the findings of an mpMRI scan and assess the likelihood of clinically significant prostate cancer.

mpMRI has been shown to be superior to traditional TRUS (Trans-rectal Ultrasound) guided biopsies in detecting clinically significant prostate cancers and can help reduce the risk of over-diagnosis and over-treatment of insignificant cancers.

However, it is important to note that no imaging modality is perfect, and the final diagnosis of prostate cancer often requires a biopsy. The decision on which imaging modality to use and whether a biopsy is necessary should be made by a healthcare professional based on the individual patient’s clinical circumstances.

Frequently Asked Questions

1. What are the different types of scans used to detect prostate cancer? The most common scans used for detecting prostate cancer are multi-parametric MRI (mpMRI), CT scans, bone scans, and PET scans. mpMRI is particularly useful for visualising the prostate gland and identifying areas of suspicion.
2. What is a multi-parametric MRI (mpMRI) and why is it important? mpMRI is a type of magnetic resonance imaging (MRI) that combines multiple sequences to provide a comprehensive assessment of the prostate gland. It can help determine the location and size of the tumour, guide targeted biopsies, and aid in treatment planning.
3. Do I need to have a biopsy after an mpMRI scan? Not necessarily. An mpMRI scan can help identify areas of suspicion within the prostate gland. If the scan indicates a low likelihood of clinically significant cancer, your doctor may recommend active surveillance instead of a biopsy. However, if the scan shows areas of concern, a targeted biopsy may be recommended to confirm the diagnosis.
4. Is a higher PI-RADS score on an mpMRI scan always indicative of cancer? A higher PI-RADS score indicates a higher likelihood of clinically significant prostate cancer. A PI-RADS score of 1 or 2 is associated with a low likelihood of clinically significant cancer, while a score of 4 or 5 is associated with a high likelihood. However, the PI-RADS score is just one part of the overall assessment, and the final diagnosis may require a biopsy.
5. Is radiation exposure a concern with prostate MRI scans? mpMRI does not involve ionising radiation, so there is no radiation exposure with this type of scan. However, other imaging modalities like CT scans and bone scans do involve exposure to ionising radiation. Your doctor will consider the risks and benefits of each imaging modality before recommending a particular scan.
6. Can I eat and drink before my mpMRI scan? You should be able to eat and drink normally before your mpMRI scan. However, it is always best to check with the imaging facility or your doctor as there may be specific instructions you need to follow before your scan.
7. Do I need to have an enema before my prostate MRI scan? It is not usually necessary to have an enema before a prostate MRI scan. However, some imaging centres may have specific preparation instructions that you need to follow. It is always best to check with the imaging facility beforehand.
8. How long does an mpMRI scan take? An mpMRI scan of the prostate typically takes around 30 to 45 minutes to complete. However, the total time may vary based on the imaging facility and the specific sequences included in the scan.
9. Is an mpMRI scan painful? An mpMRI scan is a non-invasive procedure and is not painful. However, you will need to lie still on the scanning table for the duration of the scan, which may be uncomfortable for some people.
10. Does insurance cover the cost of prostate MRI scans? Coverage for prostate cancer scans can vary significantly between different insurance providers and policies. It is advisable to check with your insurance provider to understand what is covered and what is not. Some insurance policies may cover the entire cost of the scan, while others may only cover a portion of the cost, and some may require a referral from a general practitioner or specialist.
11. Can prostate cancer be seen on the scan? Yes, prostate cancer can often be seen on an MRI scan, specifically a multi parametric MRI (mpMRI) scan, which is currently considered the best imaging technique for detecting and assessing prostate cancer. However, it’s important to note that while mpMRI is highly sensitive and specific, it is not perfect and some cancers may not be visible on the scan. Therefore, a biopsy is often required for a definitive diagnosis.
