Mayo Clinic Becomes First U.S. Institution to Deploy Magnetic Nanoparticle Hyperthermia Technology for Cancer Research
核心洞察
Mayo Clinic has installed the first magnetic nanoparticle-mediated hyperthermia machine in the United States, marking a significant milestone in cancer (搜索) treatment research.
The investigational technology uses iron oxide nanoparticles delivered intravenously that collect in tumors, which are then heated using electromagnetic waves to destroy cancer (搜索) cells.
The clinical trial focuses on patients with metastatic solid tumors (搜索) resistant to multiple treatment lines, with the first U.S. patient treated in December 2025.
Mayo Clinic has achieved a significant milestone in cancer (搜索) research by becoming the first institution in the United States to install a magnetic nanoparticle-mediated hyperthermia machine. The investigational technology, developed by Israel-based New Phase Ltd (搜索)., was installed in November 2025 at Mayo Clinic's Radiation Oncology Department in Rochester, with the first patient receiving treatment in December 2025.
Revolutionary Approach to Cancer Treatment
The hyperthermia system represents a novel approach to targeting cancer (搜索) cells through controlled heat application. "We have known for more than a century that temperature is the Achilles' heel of cancer, but conventional hyperthermia has limitations and is not widely available," explained Dr. Scott Lester, a radiation oncologist at Mayo Clinic and co-principal investigator of the clinical trial.
The technology operates through an electromagnetic induction system that targets the torso. Patients first receive iron oxide-containing magnetic nanoparticles (搜索) through an IV, which collect in tumor tissue. The patient is then positioned in the machine, where electromagnetic waves heat the tumors to help destroy cancer (搜索) cells.
Dr. Lester describes the mechanism using a familiar analogy: "It works like an induction cooktop. Induction cooktops require special pans to interact with the device. Instead of pans, the tumor absorbs the nanoparticles, effectively turning it into an induction pan." When alternating magnetic fields pulse the nanoparticles, they generate heat with a special coating that limits temperature to no more than 50 degrees Celsius.
Clinical Trial Focus and Patient Safety
The current clinical trial is evaluating the safety, feasibility, and potential effectiveness of magnetic nanoparticle hyperthermia in patients with metastatic solid tumors (搜索) in any body area except the brain. "We are focusing on patients whose cancers are resistant to multiple lines of systemic therapies and other advanced treatments, including radiotherapy," said Dr. Sean Park, radiation oncologist at Mayo Clinic Comprehensive Cancer (搜索) Center and co-principal investigator.
Patient safety is maintained through multiple monitoring systems. Cooling blankets are placed on patients to prevent excessive body temperature elevation, and the care team provides close monitoring throughout the procedure. The investigational therapy can be administered to multiple tumors simultaneously and can target cancers deep within the body.
Combination Therapy Potential
Researchers plan to study hyperthermia in combination with other established treatments, particularly radiation therapy. This approach could potentially allow for lower radiation doses while maintaining the same effectiveness or improve outcomes in radiation-resistant tumors.
"Science has taught us that hyperthermia may be the ultimate sidekick for these treatments," Dr. Lester noted. "We aim for hyperthermia to be the fourth leg of cancer (搜索) treatment, giving us a different angle to attack cancer and help patients."
Historical Context and Technological Advancement
Mayo Clinic has previous experience with hyperthermia approaches. Twenty years ago, radiation oncologists used ultrasound to heat water-filled bags placed on patients' skin, often treating women with recurrent breast cancer (搜索) after surgery and radiation. "We added the heat to enhance the effects of radiation, and there were times it was very successful," said Dr. Nadia Laack, chair of Radiation Oncology at Mayo Clinic.
However, the earlier water bag approach had significant limitations, including unreliable temperature control and patient discomfort, causing the technique to fall out of favor. Other studies demonstrating hyperthermia benefits were also constrained by technological limitations.
"Now, we may have a more advanced method to reintroduce hyperthermia into cancer (搜索) therapy," Dr. Laack explained. "If we can demonstrate its effectiveness, we can make hyperthermia more widely available to help patients with complex cancers."
Industry Collaboration and Future Implications
The collaboration between Mayo Clinic and New Phase Ltd (搜索). represents a significant investment in advancing cancer (搜索) treatment options. "The research collaboration between New Phase Ltd. and Mayo Clinic aims to open new treatment possibilities for metastatic cancer patients who currently have limited options," said Ofer Shalev, CEO and co-founder of New Phase Ltd.
New Phase Ltd (搜索). manufactures both the hyperthermia machine and the specialized nanoparticles used in the treatment. Mayo Clinic has disclosed a financial interest in this technology, indicating the institution's commitment to the research and development process.
