This week, an explanation of this exciting new therapy
What is oncothermia?
Oncothermia is also known as ‘modulated electro-hyperthermia,’ or m-EHT. It is a widely used and researched method of selectively targeting cancer cells on a cellular level by passing both focused and controlled heat, and an electric field, through cancer tissue.
Oncothermia can be used with all stages of cancer. It is mainly used with metastatic cancer and advanced solid cancers that are inoperable.
How does it work?
Simply put, an electric field is generated by two electrodes. Since cancer cells have a higher conductivity than normal cells, the electric field flows predominantly through the cancer cells, that is, it flows selectively through cancer cells. The combination of deep heat and the electric field leads to changes in the cancer cell membrane which in turn triggers cell death (known as apoptosis).
The area of the body affected by the tumour is positioned between the two electrodes. The controlled heat and electric field that flows between them is maintained in the cancer tissue for 60 minutes (sometimes longer). This leads to changes in the membrane surrounding the cancer cells and numerous biological effects including:
The immune response to oncothermia has been shown to lead to an ‘abscopal effect.’ The abscopal effect refers to a phenomenon of tumour regression at a site distant from the primary site of therapy (indicating that the therapy has not only a local effect but also a distant effect, via the immune system ie. an immunomodulatory effect). That is, therapy at the site of the primary tumour could lead to an effect on distant metastases as well.
Research shows that oncothermia also enhances the effects of chemotherapy and reduces the risk of resistance to chemotherapy drugs.
How is oncothermia different to other types of hyperthermia?
There are differences between oncothermia and classical hyperthermia at both cellular and physiological level.
In traditional hyperthermia, both cancer tissues and healthy tissues are uniformly heated. The temperature difference between cancer tissues and surrounding healthy tissue is minimal. Whilst the high temperature does not cause damage to healthy cells, the energy is spread over both cancer cells and healthy cells.
In oncothermia, the electric field and resulting heat are focused within the cancer cells.
Oncothermia results in most of the heat energy being transferred directly to the tumour. The temperature of the surrounding healthy tissue increases only very slightly.
The heat used in oncothermia is absorbed selectively by cancer cells. The surrounding healthy tissue typically remains untouched and retains its normal temperature. Due to the focused energy flow of oncothermia, more than 95% of the energy dose is absorbed into the tumour. Other classical hyperthermia systems may use higher temperatures, but this does not necessarily translate into higher heat generation within the tumour itself. It is the efficiency of oncothermia at generating a high heat selectively within tumour tissue that makes it more effective.
In other words, whilst traditional hyperthermia focuses on temperature, oncothermia works by controlling the absorbed energy, ie. the heat, within the tumour.
In addition, the efficiency of the oncothermia system means that beneficial effects are produced even with lower temperatures than those used by classical hyperthermia systems.
The cell-destruction ability of oncothermia is three times higher than that of conventional hyperthermia at the same 42°C temperature
For which types of cancer can oncothermia be used?
Oncothermia can be used with all stages of cancer although its main use is with advanced solid cancers that are inoperable, as well as with recurrent cancer and metastases.
Data is available on the use of oncothermia in many types of cancer such as the following, including advanced cases with metastases:
How effective is it?
Published data (see references below) shows that, when used as a complementary therapy along with traditional medical therapies, oncothermia can significantly improve patients’ conditions, prolong survival and enhance quality of life.
Research shows that oncothermia has numerous biological effects including influencing the immune system to recognise cancer cells, preventing cancer cells from producing new blood vessels, reactivating tumour suppressor genes such as p53 and enhancing the effects of conventional treatments.
With its unique combination of electric field and heat, oncothermia has been used with encouraging results in tumours that are in constant motion (such as lung cancers), in regions with high levels of blood flow (such as the liver) and in regions with high levels of air circulation (lungs).
Are there any side effects?
Oncothermia is an easy to use, safe, non-invasive method that can be used for any stage of cancer and with no serious reported side effects.
Data on hundreds of thousands of applications of oncothermia indicate the following general rates of side effects:
Who is using oncothermia now?
Oncothermia is used in 32 countries worldwide, mainly in Europe. It is used both in conventional cancer centres and in integrative clinics.
Oncologists present their data and experience with oncothermia at international hyperthermia conferences such as the International Clinical Hyperthermia Society.
Data and research is published in the oncothermia journal three times a year.
