Hyperthermia and immunotherapy: clinical opportunities

Area of Science:

• Oncology
• Immunology
• Thermotherapy

Background:

• Hyperthermia enhances immunotherapy's effectiveness in preclinical cancer models.
• Clinical evidence supports hyperthermia combined with radiation or chemotherapy for malignancies.
• No clinical trials have yet investigated hyperthermia directly with immunotherapy.

Purpose of the Study:

• To review the potential of combining hyperthermia with cancer immunotherapy.
• To highlight novel treatment concepts and address clinical integration questions.
• To identify promising cancer types for future clinical trials.

Main Methods:

• Review of preclinical studies on hyperthermia and cancer-immunotherapy.
• Analysis of existing clinical trials combining hyperthermia with radiation/chemotherapy.
• Discussion of potential clinical trial designs for hyperthermia-immunotherapy combinations.

Main Results:

• Hyperthermia can enhance all stages of the cancer-immunotherapy cycle.
• Potential benefits include localized heating, shorter treatment times, and better tolerance.
• Specific cancers like melanoma, bladder, and head/neck cancers are promising areas for investigation.

Conclusions:

• There is a strong rationale for investigating hyperthermia combined with immunotherapy.
• Further clinical trials are warranted to establish this combination as a viable cancer treatment.
• This approach represents a novel paradigm for anti-neoplastic therapy.
