Abstract:
Resistance to chemotherapy is the important reason for treatment failure in patients with cancer. Current methods which focus on the identification of more selective and potent drug resistance reversing agents are not satisfying. It is an urgent need for development of new approaches to overcoming drug resistance. The use of low power ultrasound in cancer therapy is a developing field. Recently, it was found that some anticancer drugs, upon ultrasonic irradiation, could create active oxygen species and effectively destruct cancer cells. This means that, in addition to cytotoxicity, these chemotherapeutic agents may be used as sonosensitizers and kill cancer cells by another mechanism. Moreover, local hyperthermia induced by ultrasound could enhance drug cytotoxicity. For the unique advantage of ultrasound, which are quite different from current therapy, we hypothesize that ultrasound assistant chemotherapy may be a new strategy to block drug resistance, which might enhance the efficacy of chemotherapeutic drugs, and reduce undesired side effects.
Insights
Ultrasound can enhance chemotherapy by creating reactive oxygen species and hyperthermia, offering a new strategy to overcome cancer drug resistance and improve treatment outcomes.
Area of Science:
- Oncology
- Biophysics
- Biomedical Engineering
Background:

- Existing methods for reversing drug resistance are insufficient.
- Novel approaches are urgently needed to overcome chemoresistance.
Purpose of the Study:
- To investigate ultrasound-assisted chemotherapy as a novel strategy against cancer drug resistance.
- To explore the potential of chemotherapeutic agents as sonosensitizers.
- To evaluate the combined effects of ultrasound-induced hyperthermia and drug cytotoxicity.
Main Methods:
- Utilizing low-power ultrasound irradiation on cancer cells with chemotherapeutic agents.
- Analyzing the generation of active oxygen species upon ultrasonic irradiation.
- Assessing the enhancement of drug cytotoxicity through ultrasound-induced hyperthermia.
Main Results:

Abdominal ultrasonography, commonly known as abdominal ultrasound, is a vital, non-invasive medical imaging technique widely used in healthcare.
Procedure:
This diagnostic tool allows the clinician to visually inspect internal structures within the abdomen, including vital organs such as the liver, gallbladder, pancreas, kidneys, and spleen.
The abdominal ultrasound process begins with applying a special gel to the patient's skin over the abdomen. This gel enhances the...
