flash Radiotherapy: A Revolutionary Leap in Cancer Treatment
Cancer treatment has long relied on radiation therapy as one of it’s foundational pillars. The principle is simple: target and destroy cancer cells with radiation. But now, flash radiotherapy is transforming this approach, delivering higher doses of radiation in a fraction of the time.This groundbreaking method is not only more effective but also gentler on healthy tissues, offering new hope to patients worldwide.

In 2014, Dr. Vincent Favaudon, a researcher at the Institut Curie, unveiled the flash effect. His work demonstrated that delivering ultra-high doses of radiation in extremely short bursts—less than 100 milliseconds—could achieve the same anti-tumor effects as conventional radiotherapy while sparing healthy tissues. This discovery marked a turning point in cancer treatment, reducing side effects like apoptosis (cell death) and skin lesions, and significantly shortening treatment sessions.
How Flash Radiotherapy Works
Conventional radiation therapy delivers doses at a rate of around 1 Gray per second,with daily fractions totaling 2 cumulative grays. In contrast, flash radiotherapy administers doses of 10 Gy or more in less than 100 milliseconds—1,000 to 10,000 times faster. This rapid delivery minimizes damage to surrounding healthy tissues, a critical advantage in treating sensitive areas.
Reaching Deep Tumors with precision
One of the most exciting advancements in flash radiotherapy is its potential to target deep-seated tumors, located 20 to 30 centimeters within tissues. Conventional low-energy electron beams struggle to reach these areas, but combining flash radiotherapy with vrey high energy electron therapy (VHEE) changes the game. VHEE beams, ranging from 100 to 250 megaelectronvolts (MeV), offer unparalleled precision, enabling treatment of cancers near vital organs that were previously inaccessible.
The FRATHEA Project: A Vision for the Future
The Institut Curie, in collaboration with the Atomic energy commission (CEA), is spearheading the FRATHEA project. This initiative aims to develop a flash-VHEE irradiator, a cutting-edge machine capable of delivering these ultra-high energy beams. The first phase involves constructing the device at the Institut Curie’s Orsay site, followed by preclinical studies to ensure safety and efficacy.if triumphant, clinical trials could begin as early as 2028, focusing on patients with poor-prognosis cancers.
A Hopeful Future for Cancer Patients
Professor Gilles Créhange, head of the oncological radiotherapy department at the Institut Curie and coordinator of the FRATHEA project, envisions a future where flash radiotherapy becomes a standard treatment for the most challenging cancers.“Power in a few years having a platform to treat patients with the most risky and inaccessible cancer. Heal better, less undergo and age better if it was necessary to summarize all clinical hopes around the flash,” he says.
Key Comparisons: Flash vs. Conventional Radiotherapy
| Aspect | Conventional Radiotherapy | Flash radiotherapy |
|————————–|——————————-|——————————|
| Dose Rate | ~1 Gy per second | ≥10 Gy in <100 milliseconds |
| treatment Duration | Minutes to hours | Less than 1 second |
| healthy tissue Impact| Higher risk of damage | Minimal damage |
| Depth of Penetration | Limited by low-energy beams | Up to 30 cm with VHEE |
Conclusion
Flash radiotherapy represents a monumental leap forward in cancer treatment. By combining speed, precision, and reduced side effects, it offers new hope for patients with deep-seated or high-risk tumors. As the FRATHEA project progresses, the dream of a more effective, less invasive treatment is becoming a reality. Stay tuned for updates on this revolutionary approach to cancer care.

Flash Radiotherapy: A Revolutionary Leap in Cancer Treatment – Insights from an Expert
Cancer treatment has long relied on radiation therapy as one of its foundational pillars. The principle is simple: target and destroy cancer cells wiht radiation. But now, flash radiotherapy is transforming this approach, delivering higher doses of radiation in a fraction of the time. this groundbreaking method is not only more effective but also gentler on healthy tissues, offering new hope to patients worldwide. to delve deeper into this revolutionary technology, we sat down with Dr. Élise moreau, a leading oncologist and researcher specializing in advanced radiation therapies.
The Flash Effect: A Game-Changer in Oncology
Senior Editor: Dr.Moreau, the concept of the flash effect has been described as a breakthrough in cancer treatment. Could you explain what it entails and why it’s so significant?
Dr. Élise Moreau: Absolutely. The flash effect was first demonstrated in 2014 by Dr. Vincent Favaudon at the Institut Curie. It involves delivering ultra-high doses of radiation in extremely short bursts—less than 100 milliseconds.This method achieves the same anti-tumor effects as conventional radiotherapy but with substantially reduced damage to healthy tissues. The key advantage is minimizing side effects like apoptosis (programmed cell death) and skin lesions, which are common with traditional methods.
How Flash Radiotherapy Works
Senior Editor: How dose flash radiotherapy differ from conventional radiation therapy in terms of dosage and delivery?
Dr. Élise Moreau: Conventional radiation therapy typically delivers doses at a rate of around 1 Gray per second, with daily fractions totaling 2 cumulative Grays. In contrast, flash radiotherapy administers doses of 10 Gy or more in less than 100 milliseconds—1,000 to 10,000 times faster.This rapid delivery minimizes exposure to surrounding healthy tissues, making it ideal for treating sensitive areas like the brain or lungs.
Reaching deep Tumors with Precision
Senior editor: One of the most exciting aspects of flash radiotherapy is its ability to target deep-seated tumors. How does this work, and what makes it so effective?
Dr. Élise Moreau: Traditional low-energy electron beams struggle to penetrate tissues beyond a certain depth. However, flash radiotherapy combined with very high energy electron therapy (VHEE) can deliver beams ranging from 100 to 250 megaelectronvolts (MeV). This allows us to reach tumors located 20 to 30 centimeters deep with unparalleled precision. It’s a game-changer for cancers near vital organs that were previously considered untreatable.
The FRATHEA Project: A Vision for the Future
Senior Editor: The FRATHEA project is gaining attention for its aspiring goals. Can you tell us more about this initiative and its potential impact?
Dr. Élise Moreau: The FRATHEA project, led by the Institut Curie in collaboration with the Atomic Energy Commission (CEA), aims to develop a flash-VHEE irradiator. This cutting-edge machine will deliver ultra-high energy beams for precise cancer treatment.
