Discover how biomarkers personalize and guide prostate cancer treatment decisions for each patient.

Imagine a treatment that takes you into account—your story, the biology of your cancer, and how your health evolves over time.

What you’re imagining is personalized medicine. This rapidly growing field is driven by advances in genetics and molecular biology, and by an essential tool: biomarkers.

In this article, PROCURE explains:

• What personalized medicine is
• How biomarkers inform each stage of treatment
• What these advances mean for the future
• How you can prepare for next steps with your care team

What is personalized medicine?

When it comes to cancer, no two journeys are the same. That’s why personalized medicine—also known as precision medicine—is based on your history, who you are, and the unique characteristics of your body. Its principle is simple, yet deeply human.

Rather than applying the same treatment to everyone, personalized medicine relies on modern tools like biomarkers to offer care tailored specifically to you.

Benefits of using biomarkers:

• Enables early intervention with a targeted, effective strategy
• Makes it possible to avoid aggressive treatments and live well with active surveillance
• Helps adjust treatments over time, staying one step ahead of the disease in more complex or advanced cases

Personalized medicine evolves with you—and for you.

The central role of biomarkers

In the often complex journey of prostate cancer, every piece of information matters. The better the disease is understood, the better it can be managed. That’s where biomarkers play a key role.

They are biological clues— invisible to the naked eye—found in blood, urine, tumor tissue, or even circulating DNA. They help healthcare professionals answer essential questions:

• Is the cancer aggressive or slow-growing?
• Is there a high risk of progression?

Biomarkers therefore help to:

• Personalize care
• Avoid unnecessary treatments
• Choose the most effective therapies
• Monitor treatment effectiveness
• Detect the risk of recurrence or resistance to certain medications

Biomarkers are not just medical tools—they are trusted allies at every step, guiding decisions and making medicine more human, precise, and reassuring.

How do biomarkers work in practice?

• Before treatment – Biomarkers such as PSA and certain genetic tests help assess risk and determine whether monitoring or intervention is appropriate. The Gleason score is also part of this evaluation.
• During treatment – Some biomarkers indicate whether a treatment is working. If it isn’t, the strategy can be adjusted quickly.
• In cases of recurrence or advanced cancer – Tumor DNA or specific proteins can be analyzed to identify therapeutic targets—such as mutations that may respond to a specific drug.

Here are concrete examples in prostate cancer:

• Genetic mutations: Patients with mutations such as BRCA2 may benefit from specific targeted therapies.
• Risk of recurrence: Genetic tests on tumor tissue can help predict the risk of recurrence after surgery or radiation therapy.
• Cancer progression: Emerging biomarkers may allow cancer monitoring through a simple blood test, reducing the need for more invasive exams.

What can we expect in the coming years?

Personalized medicine is becoming increasingly accessible and precise. Thanks to technological advances, physicians will be able to:

• Offer more effective treatments with fewer side effects
• Reduce unnecessary treatments
• Provide tailored options, even for advanced cancers

This approach truly places patients at the center of decision-making, taking into account not only biology, but also values and personal preferences.

Key takeaways and next steps

Personalized medicine is transforming how prostate cancer is understood and treated. Thanks to biomarkers, treatments are becoming more precise, more tailored, and more respectful of each individual’s reality.

Possible next steps with your healthcare team:

• Discuss which biomarkers have already been assessed or should be considered
• Ask whether genetic testing may be relevant for your situation
• Understand how your results influence your treatment options
• Establish a personalized follow-up plan
