Hyperthermia in cancer research: current status

Area of Science:

• Oncology
• Biophysics
• Cell Biology

Background:

• Hyperthermia (HT) involves exposing tissues to high temperatures, which can cause cell death and tissue damage.
• Clinical applications of HT leverage its ability to induce localized tumor tissue damage, making it a potential adjuvant therapy for cancer.
• Despite a strong biological rationale and early promise, HT's clinical use is mainly limited to superficial tumors.

Purpose of the Study:

• To review and analyze published literature on hyperthermia (HT) in cancer treatment over the last 15 years.
• To explore the biological mechanisms underlying HT's effects on cancer cells and tissues.
• To identify factors limiting HT's clinical application and suggest areas for future research.

Main Methods:

• Systematic review of scientific literature published in the last 1.5 decades.
• Analysis of experimental data and clinical experiences with hyperthermia in cancer therapy.
• Examination of biological mechanisms, drug interactions, and tumor microenvironment factors.

Main Results:

• Hyperthermia demonstrates a strong biological basis for cancer treatment, particularly as an adjuvant to radiotherapy.
• Current clinical applications are restricted, primarily to superficial tumors, indicating a need for broader implementation strategies.
• Understanding HT's interaction with chemotherapy, radiation, and the tumor microenvironment (e.g., oxygen, pH) is crucial.

Conclusions:

• Further laboratory investigations and clinical trials are essential for realizing the full potential of hyperthermia in cancer therapy.
• Refining clinical implementation requires a deeper understanding of HT's mechanisms, thermotolerance kinetics, and interactions.
• Addressing limitations in current applications will pave the way for more effective use of hyperthermia in treating various malignancies.
