Evaluation of the role of Lymphadenectomy In high-risk Prostate cancer SurgEry

Medical Conditions

Biopsy-proven clinically localised high-risk prostate cancer


This information is provided directly by researchers, and we recognise that it isn't always easy to understand. We are working with researchers to improve the accessibility of this information. In some summaries, you may come across links to external websites. These websites will have more information to help you better understand the study.


Every year in the UK, nearly 50,000 people are diagnosed with prostate cancer and over 10,000 men die from it. Prostate cancer that has not spread elsewhere in the body but is at risk of doing so is referred to as high-risk localised prostate cancer. Established treatment options for high-risk prostate cancer are surgery and radiotherapy. In the UK, 4000 patients a year undergo surgery for high-risk prostate cancer. When surgeons operate on men with high-risk prostate cancer, they remove the entire prostate gland and, in some cases, also remove the nearby lymph nodes (an immune tissue that forms the early landing sites for cancer spread) in a surgery called pelvic lymph node dissection (PLND). It is thought that PLND gives better cancer clearance and reduces recurrence, which is seen in 30-50% of men with high-risk disease. However, complications can arise from PLND. These complications may reduce the quality of life, and along with the increased surgical time required, lymph node surgery in addition to removing the prostate might result in additional costs to the NHS. The study team surveyed UK surgeons and found variable practice with 35% of eligible patients getting lymph node excision. Surgeons stated that the current evidence was not good enough to inform decisions about whether it was beneficial to do a lymph node excision knowing that there are potential harms, and a clinical trial comparing lymph node excision to no lymph node excision was urgently required. This clinical trial aims to compare the two treatments in terms of their effect over 3 years on, prostate cancer recurrence, quality of life, complication rates, survival and use of NHS resources. Everyone who takes part will have an equal chance of either having their lymph nodes removed or not during their prostate cancer PCa surgery. The study will recruit 1080 patients from 25 hospitals across the UK.

Start dates may differ between countries and research sites. The research team are responsible for keeping the information up-to-date.  

The recruitment start and end dates are as follows:

01 Sep 2024 31 Aug 2026

Adults who consent to participate in ELIPSE will be randomly allocated to one of the two types of surgery mentioned above. After the surgery, they will be sent participants questionnaires for up to 36 months to collect information on several things, including cancer recurrence, harms, quality of life, time to return to normal activities, and costs. Further information will also be collected from their routine follow-up that is recorded in their medical records.


Adults aged 18 years old and over with biopsy-proven clinically localised high-risk prostate cancer who are suitable for radical prostatectomy

You can take part if:



You may not be able to take part if:


1. Hormone therapy within the 3 months prior to consent2. Previous radical treatment for PCa (radical treatment includes radical prostatectomy and/or radiotherapy and/or focal therapy [eg cryotherapy or HIFU])3. Unsuitable for surgical treatment4. People without capacity

Participants may not benefit personally from taking part but, by taking part, will help inform the treatment of future patients who need to have radical prostatectomy. The results of the ELIPSE study will help doctors, surgeons, patients and health services decision-makers understand whether it is better to remove lymph nodes during a radical prostatectomy, or not. Both types of surgery are already being used in the NHS to treat patients. There are risks associated with all surgical procedures but there should be no additional risk in taking part in the study.
