Radiofrequency ablation (RFA)

Radiofrequency ablation (RFA) is a treatment method used to treat various types of cancer such as breast cancer, colorectal cancer and hepatocellular carcinoma (HCC) as well as inoperable metastases. The method uses medical devices that operate between 460 and 550 kHz and deliver therapeutic energy.

How it works:

Therapeutic energyrFA induces heat-induced necrosis in tumour tissue by raising the temperature to approximately 100°C for about 15 minutes.

Target tissuethe energy is applied specifically to the tumour tissue to destroy the cancer cells.

Areas of application:

Breast cancer

Colorectal cancer

Hepatocellular carcinoma (HCC)

Non-operable metastases

Advantages:

Targeted treatmentrFA enables precise destruction of tumour tissue.

Minimal invasivenessthe method is less invasive than surgery and can be used in patients for whom surgery is not possible.

Clinical data:

Anti-tumour effectslaboratory and clinical data show that certain frequencies in the RF EMF range can have antitumour effects in patients with various types of cancer.

FDA approvalthe NovoTTF-100A device, which uses alternating electric fields, has been approved by the FDA and demonstrated efficacy comparable to standard chemotherapy in a Phase III trial, but with fewer side effects.

Summary:

RFA is a promising method of treating cancer that destroys tumour tissue through the targeted application of radiofrequency energy. The method offers advantages in terms of precision and minimal invasiveness and has shown positive results in clinical studies.
