Anti-tumor Mechanism of Sonodynamic Combined with Hyperthermia and Its Application in Tumor

Sonodynamic therapy (SDT) is a new non-invasive treatment method that uses a combination of sono-sensitizers and low-intensity ultrasound (US) to treat malignant tumors. SDT is developed from photodynamic therapy (PDT). Because ultrasound can be transmitted deeper than light in tissues, sonosensitiz...

Summary:Sonodynamic therapy (SDT) is a new non-invasive treatment method that uses a combination of sono-sensitizers and low-intensity ultrasound (US) to treat malignant tumors. SDT is developed from photodynamic therapy (PDT). Because ultrasound can be transmitted deeper than light in tissues, sonosensitizers can be induced to be targeted, and sonosensitizers can be monitored in real time through ultrasound, SDT has significant advantages of locating the tumor site and activating the sensitizing agent in deep tissues. Therefore, compared with PDT, SDT can be used to treat tumors that are wider, deeper and more inaccessible. Hyperthermia (HT), as an adjuvant therapy, is applied to various established cancer treatments. Its mechanism is to increase the temperature of the tumor-bearing tissue to 40℃-43℃ to cause irreversible damage. This article reviews the cell signal regulation mechanism involved in SDT and HT in tumor therapy and the application progress of SDT-HT combination therapy on tumor.
