When it comes to therapeutic hyperthermia, one principle rises above all others: Thermal dose matters.
This simple but powerful truth is at the heart of every successful hyperthermia treatment. The temperature you reach—and how long it’s maintained—directly determines whether a treatment is biologically effective.
The Science Behind Thermal Doseage
Hyperthermia works by safely heating tumors to temperatures that stress and sensitize cancer cells while supporting healthy tissue recovery. But not all heat is created equal. Clinical studies have shown that the precise thermal dose—the amount of energy absorbed by the tissue over time—has a direct, measurable effect on outcomes.
Two landmark studies in cervical cancer patients highlight this relationship clearly:
Franckena et al., 2009 (420 patients): Higher thermal dose parameters (CEM43T90, TRISE) were powerful predictors of tumor response, local control, and overall survival.
Kroesen et al., 2019 (227 patients): Even with modern radiotherapy, patients who received a higher thermal dose achieved better local control and improved outcomes.
These studies confirm that accurate, reproducible thermal dosing is essential. Without it, hyperthermia cannot reach its full therapeutic potential.
Thermofield: Engineered for Precise, Reliable Thermal Dosing
When lives are on the line, reproducibility is not optional. That’s why Thermofield was designed by electrical engineers—to ensure every treatment delivers a clinically meaningful and verifiable thermal dose.
Here’s how Thermofield ensures safety, consistency, and precision in every session:
Consistent Thermal Dose — Not Guesswork
- Multi-hour calibration achieves up to 99% efficiency.
- A patented bi-directional coupler verifies performance in real time.
- If efficiency drops below 70%, the system alarms and prompts an applicator adjustment—eliminating uncertainty.
Safer, More Even Tumor Heating
- Center-feed applicator evenly distributes energy for smoother, deeper heating.
- Reduces hot spots while maintaining therapeutic temperatures across the target area.
Energy Directed Where It Matters
- Integrated shielding focuses energy forward—maximizing tumor heating while minimizing surface exposure.
- Protects staff and nearby equipment from stray RF emissions.
Confidence in Every Session
- Built-in safeguards alarm and shut down automatically if efficiency drops or sensors fail.
- Prevents unmonitored or ineffective treatments.
Aerospace-Level Engineering
- Designed to NASA specifications by certified electrical engineers.
- Powered by a medical-grade external supply (IEC 60601 compliant) that converts wall current into safe, low-voltage DC—reducing electrical risk and extending device lifespan.
Independently Tested and Certified
- Passed FCC testing in a certified lab for compliance with U.S. electromagnetic emission standards.
Validated in Human Use
In a Phase I study (80 treatments, 20 volunteers), Thermofield demonstrated strong safety and physiological effects:
- Well tolerated: Only mild, temporary erythema at higher therapeutic temperatures.
- Significant blood flow increase: Doppler data showed 400%–800% rise in circulation (Wake Forest data on file).
- Findings consistent with classic research by Song (Cancer Research, 1984) showing that heating healthy tissue to 43–45°C dramatically increases blood flow—an essential part of hyperthermia’s therapeutic action.
The Bottom Line
Hyperthermia only works when the tumor consistently receives the right thermal dose. That’s why Thermofield was built—to bring precision, reproducibility, and unmatched safety to every treatment session.
With its advanced monitoring systems, aerospace-grade engineering, and verified human data, Thermofield represents the next generation of integrative oncology technology—combining science, safety, and performance for optimal patient outcomes.
