Spots Global Cancer Trial Database for Contrast Enhanced Ultrasound to Evaluate Response to Chemoembolization in Patients With Liver Tumors

Study Description

Brief Summary: This phase II trial evaluates the diagnostic performance of contrast-enhanced ultrasound (CEUS) for assessing treatment response in patients undergoing transarterial chemoembolization (TACE) for liver tumors. TACE is a hepatic artery embolization technique involving the injection of a blocking agent and a chemotherapy agent to treat liver cancers. Currently, contrast enhanced magnetic resonance imaging or computed tomography are used to assess disease response 1-2 months after TACE treatment, but ultrasound may be a less expensive, earlier alternative. CEUS is an imaging procedure that uses high-frequency sound waves to generate images of the body after administering lumason, an imaging agent used to enhance visualization of blood flow on ultrasounds. CEUS is able to be performed during the TACE procedure, making it possible to evaluate treatment response earlier than standard techniques. CEUS may be an effective method to evaluate treatment response more accurately and much earlier than current standard evaluation methods.

Detailed Description: PRIMARY OBJECTIVE: I. To evaluate the sensitivity and specificty of CEUS for the evaluation of TACE treatment response in a variety of solid liver tumors (years 1-4). SECONDARY OBJECTIVES: I. To determine the ability of CEUS to identify residual tumor vascularity intraoperatively, thereby enabling immediate retreatment when necessary (years 1-4). II. To explore a variety of advanced imaging approaches to improve on the suboptimal specificity of CEUS for identifying residual viable tumor following TACE (years 1-5). III. To investigate the ability of CEUS obtained prior to TACE to quantitatively assess tumor vascular morphology and predict response to therapy (years 2-5). EXPLORATORY OBJECTIVE: I. Use acquired B-mode in-phase and quadrature (IQ) data for H-scan imaging. OUTLINE: Patients receive lumason intravenously (IV) and undergo CEUS 2 weeks prior to TACE, during TACE, 1-2 weeks after TACE, and then 1-2 months after TACE. After completion of study treatment, patients are followed up at 6 months.
