What Is Hyperthermia Cancer Treatment?
Hyperthermia treatment involves carefully heating tumor tissue to temperatures between 39-45°C (102-113°F) to enhance cancer therapy effectiveness. As Dr. Stephan Bodis, MD, explains, this approach has evolved significantly from early experimental treatments decades ago to become a precision medicine tool in modern oncology.
The radiation oncology professor notes that while hyperthermia showed promise 30-40 years ago, technological limitations initially hindered widespread adoption. Today's advanced heating systems allow more controlled, targeted application of therapeutic heat alongside other cancer treatments.
Why Hyperthermia Works Best With Other Treatments
Dr. Stephan Bodis, MD, emphasizes that hyperthermia is not a standalone cancer treatment. "Hyperthermia should either be combined with ionizing radiotherapy for local treatments or with chemotherapy for systemic approaches," the Zurich-based oncologist states. This combination strategy maximizes treatment effectiveness while minimizing side effects.
Clinical trials demonstrate that adding hyperthermia to conventional cancer therapies can allow lower doses of radiation or chemotherapy drugs while maintaining or improving tumor response rates. This dose-sparing effect significantly reduces treatment toxicity for patients.
Hyperthermia's Role in Radiosensitization
One of hyperthermia's most valuable applications is enhancing tumor sensitivity to radiation therapy. Dr. Stephan Bodis, MD, explains that heating tumor tissue creates multiple biological effects that make cancer cells more vulnerable to radiation damage.
The heat therapy improves oxygen delivery to tumors (reducing radioresistant hypoxic areas), disrupts cancer cell DNA repair mechanisms, and increases blood flow to help radiation work more effectively. These synergistic effects allow radiation oncologists to achieve better results with potentially lower radiation doses.
Reducing Chemotherapy Toxicity With Heat Therapy
When combined with chemotherapy, hyperthermia can enhance drug penetration into tumors and increase cancer cell membrane permeability. Dr. Stephan Bodis, MD, notes this allows oncologists to use lower chemotherapy doses while maintaining treatment effectiveness - a crucial benefit for patients facing systemic therapy.
The heat therapy appears particularly valuable for certain chemotherapy drugs where temperature-dependent effects have been well documented. This combination approach helps minimize chemotherapy's damaging effects on healthy tissues while maintaining strong anti-tumor activity.
Optimal Temperature Ranges for Cancer Treatment
Dr. Stephan Bodis, MD, clarifies that therapeutic hyperthermia typically operates in the 39-45°C range, with temperatures above 45°C considered thermoablation - a more aggressive approach that overlaps with surgical techniques. The specific temperature range used depends on the tumor type, location, and combination treatment plan.
Precise temperature control represents one of the most significant advances in modern hyperthermia oncology, allowing clinicians to target tumors while protecting surrounding healthy tissues. This precision makes hyperthermia particularly valuable for treating cancers in sensitive anatomical locations.
Current Advances in Hyperthermia Oncology
According to Dr. Bodis, hyperthermia is experiencing renewed interest in academic medical centers after previous periods of limited adoption. The European Society of Hyperthermic Oncology (ESHO) recently highlighted growing evidence supporting hyperthermia's role in comprehensive cancer care.
Modern technological improvements in heating equipment, temperature monitoring, and treatment planning have addressed many historical limitations. These advances now allow hyperthermia to be effectively integrated with other precision cancer therapies in hospital settings.
The Value of Medical Second Opinions for Hyperthermia Treatment
Dr. Anton Titov, MD and Dr. Stephan Bodis, MD, discuss how second opinions can help patients access optimal hyperthermia combination therapies. As hyperthermia protocols continue to evolve, consulting with specialists at leading centers ensures patients receive the most current, evidence-based treatment approaches.
Second opinions are particularly valuable for determining whether hyperthermia could enhance conventional radiation or chemotherapy plans while reducing treatment toxicity. This collaborative approach helps create truly personalized cancer treatment strategies incorporating the latest therapeutic advances.

Dr. Stephan Bodis, MD: Hyperthermia is not a stand-alone treatment modality. Hyperthermia is used together with chemotherapy and radiation therapy. Hyperthermia allows lowering cancer chemotherapy and radiotherapy doses.
Hyperthermia in cancer treatment sensitizes tumors to radiotherapy. Its use in cancer treatment is increasing. Adding hyperthermia to a cancer treatment plan can decrease therapy toxicity.
Hyperthermia should either be combined with ionizing radiotherapy for local treatments or with chemotherapy for systemic treatments. Medical second opinions help confirm radiotherapy with hyperthermia cancer treatment plans and ensure the best combination therapy is included in comprehensive personalized cancer treatment.
Dr. Anton Titov, MD: One of your major clinical interests is hyperthermia in cancer treatment, particularly its use in radio-sensitization of tumors. You've designed strategies to make tumors more sensitive to radiation therapy. Hyperthermia, or increased body temperature, is one such radiotherapy-sensitizing strategy.
You published a review of modern clinical trials about hyperthermia treatments in cancer, discussing its combination with radiation therapy. How is hyperthermia used in cancer treatment today? What is a major theme in using hyperthermia for radiosensitization of tumors?
Dr. Stephan Bodis, MD: I would like to answer this question in two parts, based on our recent discussions during the last ESHO meeting. ESHO is the European Society of Hyperthermic Oncology, where we had panel discussions about hyperthermia use in cancer treatment.
The history of hyperthermia in cancer therapy is complex. About 30-40 years ago, hyperthermia was considered very promising based on biological principles. Unfortunately, its use decreased due to lack of technology and integration in academic hospital settings.
We believe times have changed now. There's a good argument for using hyperthermia as an important discipline for selected cancer patients. Hyperthermia is not a single treatment modality to be used alone.
It should either be combined with ionizing radiotherapy for local treatments or with chemotherapy for systemic cancer treatment plans. I would like to focus on regional and locoregional hyperthermia.
Hyperthermia can be given in a temperature range between 39 and 45 degrees. Sometimes it's more than 45 degrees, which we call thermoablation, entering the field of surgery.
