    Summary

    Hyperthermia therapy, using heat (40-43°C), enhances cancer treatment by affecting tumor cell proliferation and radiosensitivity. It also boosts the effectiveness of chemotherapy drugs, offering a promising adjunct to radiation therapy.

    Area of Science:

    • Oncology
    • Biophysics
    • Radiotherapy

    Background:

    • Hyperthermic tumor therapy research has significantly increased.
    • Clinical hyperthermia typically ranges from 40-43°C, as higher temperatures pose physiological risks.
    • Heat influences tumor cell proliferation, synchronizes cell cycles, and affects cells in hypoxic conditions.

    Purpose of the Study:

    • To review the effects of hyperthermia on tumor cells and its potential as an adjunct cancer therapy.
    • To explore hyperthermia's synergistic effects with radiation and chemotherapy.
    • To identify challenges in clinical hyperthermia application.

    Main Methods:

    • Review of existing literature on hyperthermia in cancer therapy.
    • In vitro and in vivo experimental studies on tumor cell response to heat.
    • Analysis of hyperthermia's interaction with radiation (X-rays, gamma rays, neutrons, heavy ions) and cytostatic drugs.

    Main Results:

    • Hyperthermia impacts tumor cell proliferation, particularly M-phase and S-phase cells, and can synchronize cell cycles.
    • Heat enhances the efficacy of radiation therapy, especially when combined with sparsely ionizing radiation, offering an alternative to densely ionizing radiation.
    • Hyperthermia potentiates the effects of various cytostatic drugs, with some drugs showing increased effectiveness above 42°C.

    Conclusions:

    • Hyperthermia is a valuable tool in cancer therapy, enhancing both radiation and chemotherapy efficacy.
    • Challenges remain in achieving homogeneous heating of large solid tumors in clinical settings.
    • Further research into optimizing hyperthermia application is crucial for improving patient outcomes.
