Effects of EPA on Prostate Cancer Cells Proliferation and Quality of Life
This research is investigating whether a specific type of omega-3 fatty acid found in fish oil, called EPA, can help men with prostate cancer. We want to see if taking an EPA supplement might affect the growth of prostate cancer cells. Additionally, the study aims to understand if EPA can improve a patient's overall well-being, including their mood and general quality of life, especially since some studies suggest omega-3s could help with depression in cancer patients. Participants will take either the EPA supplement or a dummy pill (placebo) for a period, starting before surgery and continuing for a year afterwards. This study could help us learn if a simple dietary change might benefit men with prostate cancer.
At a glance
What is this study about?
This study is looking into how a special type of omega-3 fatty acid called EPA, found in fish oil, might affect men with prostate cancer. Prostate cancer is very common, and researchers are always trying to find new ways to help patients.
Previous studies have hinted that diets rich in omega-3 fatty acids might offer some protection against prostate cancer. We also know that inflammation in the body might play a role in how prostate cancer develops and how patients feel emotionally. This study wants to see if EPA, which is known for its anti-inflammatory properties, can help slow down the cancer cells and also improve a patient's mood and overall quality of life. Sometimes, cancer and its treatments can affect how people feel, so finding something that could help with well-being is important.
The idea for this study also comes from earlier work which suggested that higher levels of EPA in the prostate might be linked to a lower risk of prostate cancer becoming more severe. This trial hopes to build on that knowledge and see if taking an EPA supplement directly can have these positive effects. If successful, this simple dietary change could eventually become a helpful part of care for men with prostate cancer.
Key takeaways
- Tests fish oil (EPA) for prostate cancer and well-being.
- Aims to see if EPA slows cancer and improves mood.
- Compares EPA to a dummy pill (placebo).
- Participation involves taking capsules daily for over a year.
- Could lead to new simple support for men with prostate cancer.
Who may be eligible?
This study is specifically looking for men who have been diagnosed with a more serious type of prostate cancer (which doctors call 'high-grade'). You should have decided with your doctor to have an operation called a 'radical prostatectomy' to remove your prostate.
To join, you must be willing to stop taking any omega-3 supplements, like fish oil capsules, for at least three months before the study starts. This is important so that the researchers can clearly see the effects of the study supplement. You also need to be willing to give your 'informed consent', which means you understand what the study involves and agree to take part.
However, you won't be able to join if you have allergies to fish or sunflower products, as these are used in the study supplements. Also, if you have a condition called bipolar disorder, you won't be eligible to take part.
Could this study suit you?
Answer these quick questions to see if you may be eligible. This is a guide only — the research team makes the final call.
- Do I have a higher-risk type of prostate cancer?
- Have I chosen to have surgery (radical prostatectomy)?
- Am I willing to stop taking any other omega-3 supplements for 3 months?
- Do I agree to understand and sign the consent forms?
- Do I have any fish or sunflower allergies?
- Do I have bipolar disorder?
What does participation involve?
If you decide to take part, you will be given either the active study supplement (fish oil rich in EPA) or a dummy pill (placebo, which looks the same but contains sunflower oil). You won't know which one you're taking, and neither will your care team. You'll need to take this supplement every day.
The study will start about six weeks before your planned prostatectomy surgery. You will continue taking the daily capsules for a full year after your surgery. During this time, you'll have regular check-ups and assessments, just as you would normally for your prostate cancer care. The research team will also collect extra information about your health, diet, and how you're feeling, including your quality of life. The total duration of your participation, including the lead-up to surgery and the follow-up, will be around 14 months.

Common questions
What is EPA?
EPA is a type of omega-3 fatty acid, commonly found in fish oil, that some studies suggest has anti-inflammatory effects and may influence cancer cells.
What is a placebo?
A placebo is a 'dummy' pill that looks just like the real medicine but contains no active ingredients. It helps researchers compare effects fairly.
Why do I need to stop other omega-3s?
Stopping other omega-3 supplements ensures that any effects seen in the study are clearly due to the EPA supplement being tested, not other products.
How long will I be in the study?
You'll be in the study for about six weeks before your surgery and then for one year afterwards, meaning a total of approximately 14 months.
Will I know if I'm taking the EPA or the placebo?
No, this is a 'double-blind' study, meaning neither you nor your doctors will know which treatment you are receiving until the study is over.
