Hyperthermia is currently used mostly in combination with radiation therapy or chemotherapy, rather than as a standalone treatment that replaces surgery, radiation, or chemotherapy. Whether and how it is combined should be assessed by the care team.
How is hyperthermia typically combined with other treatments?
According to the National Cancer Institute (NCI), hyperthermia is “almost always used with other forms of cancer treatment.” In a small number of cases, local hyperthermia limited to a small tumor area (such as radiofrequency ablation) may be used on its own to remove a tumor, but in most cases it is still combined with radiation therapy or chemotherapy.
Does hyperthermia make other treatments “more effective”?
The American Cancer Society (ACS) states that regional and whole-body hyperthermia “seem to” help other forms of cancer treatment work better — the general mechanism proposed is that raising cancer cells’ temperature above normal may make them easier to kill with radiation therapy and certain chemotherapy drugs.
The above reflects a general research direction described by ACS using hedged language (“seem to”). Actual effects vary by individual condition, cancer type, and treatment plan. This does not mean any specific medical device has been proven to have this effect, nor is it a Taiwan-approved indication or efficacy claim.
Does this mean hyperthermia is an established standard treatment?
No. ACS explicitly states that hyperthermia is currently “largely experimental,” requiring special equipment and a care team with relevant experience — which is why it is not offered at all cancer treatment centers.
Can hyperthermia replace surgery, radiation, or chemotherapy?
No. Publicly available educational materials consistently position hyperthermia as an adjunct to standard treatment, not a replacement. Whether it is suitable to combine, and how, should be decided by an oncology care team based on the individual patient's condition.
