Sonodynamic Therapy
What is Sonodynamic Therapy?
Sono Dynamic Therapy (SDT) is a treatment in which a photosensitive substance that has the property of collecting in tumor tissue and new blood vessels is administered to the patient, and ultrasound is then applied to the area where the photosensitive substance has collected, causing a photochemical reaction in the photosensitive substance, generating reactive oxygen species that have a cytotoxic effect, and causing the degeneration and necrosis of cancer cells.
Because ultrasound can penetrate deeper into tissues than light, sonodynamic therapy can attack cancer cells at deeper levels than photodynamic therapy.
Characteristics of Sonodynamic Therapy
1. Minimally invasive treatment (treatment with less strain on the body)
There is no need to make an incision in the body, and there is no need to use burdensome anesthesia such as general anesthesia during treatment.
2. Almost no damage to normal cells
Because the drugs act specifically on cancer cells, treatment can be carried out while protecting healthy cells.
3. It can approach deep cancer
Ultrasound can reach deeper than light, so it can approach deep-seated cancers (lung cancer, prostate cancer, liver cancer, pancreatic cancer, etc.).
4. It can be performed as an outpatient treatment
There is no need for hospitalization and no sacrifice of daily life.
About Photoimmunotherapy
At our clinic, we do not only use sonodynamic therapy alone, but also perform photoimmunotherapy using selected wavelengths of laser, near-infrared light, and ultrasound, or in combination, according to the patient's condition and type of cancer. We use different devices for irradiation methods according to the patient's condition, such as intradermal irradiation, intravascular irradiation, and external point or surface irradiation. By using near-infrared light and ultrasound, we can also treat deep cancers that are difficult for light to reach.
