Perspectives on Recent Progress in Focused Ultrasound Immunotherapy

Area of Science:

• Oncology
• Immunology
• Medical Physics

Background:

• Immunotherapy shows promise for solid tumors but faces challenges like poor T cell infiltration and adaptive resistance.
• Focused ultrasound (FUS) is a non-invasive technique for targeted energy deposition, gaining attention for immune modulation in cancer.
• Previous reviews highlighted FUS's potential and challenges; recent activity necessitates an update.

Purpose of the Study:

• To provide an updated overview of scientific and clinical advancements in focused ultrasound (FUS) immunotherapy.
• To discuss the progress and perspectives in combining FUS with immunotherapy for cancer treatment.

Main Methods:

• Review of recent scientific literature and clinical trial data on FUS immunotherapy.
• Analysis of presentations at therapeutic ultrasound scientific meetings over the past two years.

Main Results:

• A significant increase in clinical trials exploring FUS for various cancers, including combination with immunotherapy.
• Growing interest and presentations on FUS immunotherapy at scientific conferences.
• Emergence of FUS as a strategy to enhance T cell infiltration and overcome resistance in solid tumors.

Conclusions:

• Focused ultrasound immunotherapy is a rapidly advancing field with growing clinical translation.
• FUS holds significant potential to enhance the efficacy of immunotherapy for a broader range of cancer patients.
• Continued research and clinical trials are crucial to fully realize the therapeutic benefits of FUS immunotherapy.
