Ultrasound-driven sonodynamic therapy for hepatocellular carcinoma

Area of Science:

• Oncology
• Biomedical Engineering
• Photodynamic Therapy

Background:

• Hepatocellular carcinoma (HCC) presents significant clinical challenges due to its high malignancy, recurrence rates, and poor prognosis.
• Current HCC treatments often lack precision, exhibit limited efficacy, and cause substantial side effects, highlighting the need for innovative therapeutic strategies.
• Sonodynamic therapy (SDT) is an emerging treatment modality that utilizes ultrasound to activate sonosensitizers, leading to the generation of reactive oxygen species for cancer cell destruction.

Purpose of the Study:

• To review the current landscape of Sonodynamic Therapy (SDT) for Hepatocellular Carcinoma (HCC) management.
• To provide a foundational understanding of SDT principles and applications in HCC.
• To guide future research and clinical translation of SDT in HCC therapy.

Main Methods:

• Literature review of existing studies on SDT for HCC.
• Analysis of sonosensitizer mechanisms and ultrasound activation in cancer models.
• Evaluation of preclinical and clinical data regarding SDT efficacy and safety in HCC.

Main Results:

• SDT demonstrates potential in generating cytotoxic reactive oxygen species upon ultrasound activation.
• Various sonosensitizers have shown promise in preclinical HCC models, inducing tumor suppression.
• Further research is needed to optimize SDT parameters and sonosensitizers for clinical efficacy and safety in HCC.

Conclusions:

• Sonodynamic therapy (SDT) offers a promising, non-invasive approach for Hepatocellular Carcinoma (HCC) treatment.
• The review consolidates current knowledge, identifying key areas for future investigation to advance SDT towards clinical application.
• SDT holds potential as an effective therapeutic strategy to overcome limitations of existing HCC treatments.
