Contrast-Enhanced Ultrasound in Predicting Treatment Response in Patients With Kidney Cancer Undergoing Cryosurgery

Contrast-Enhanced Ultrasound for the Evaluation of Renal Cell Carcinoma Cryoablation

This pilot clinical trial compares the imaging results of contrast-enhanced ultrasound to contrast-enhanced magnetic resonance imaging (MRI) or computed tomography (CT), the current clinical standard, in predicting treatment response in patients with kidney cancer undergoing cryosurgery (a procedure in which an extremely cold liquid or an instrument called a cryoprobe is used to freeze and destroy abnormal tissue). Using contrast-enhanced ultrasound that does not involve a dye may help patients avoid side effects from a dye that is usually used in MRI or CT and may help doctors measure blood flow and determine whether the cryosurgery procedure treated the kidney tumor.

Study Overview

Detailed Description

PRIMARY OBJECTIVES:

I. Evaluate if contrast-enhanced ultrasound can be used to successfully evaluate the cryoablation (cryosurgery) of renal cell carcinoma.

SECONDARY OBJECTIVES:

I. Establish whether contrast-enhanced ultrasound provides a reliable tool for the characterization of renal masses prior to cryoablation.

TERTIARY OBJECTIVES:

I. Compare harmonic imaging (the current industry standard for contrast imaging) with subharmonic imaging (a novel, improved contrast imaging technique) in the two aims listed above.

OUTLINE:

Patients receive perflutren protein-type A microspheres intravenously (IV) and then undergo contrast-enhanced ultrasound imaging the morning prior to cryosurgery and at 3-4 months post treatment during MRI or CT follow up.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Sensitivity - Ability of contrast-enhanced ultrasound to successfully evaluate the cryoablation of renal cell carcinoma
Time Frame: Up to 3-4 months after cryosurgery
Sensitivity will be calculated for the contrast-enhanced ultrasound exam using both the standard of care contrast-enhanced CT or MRI, and patient outcome as the reference standard. Correlations between these findings and both contrast-enhanced MRI or CT findings and patient outcomes will be compared using the Fisher exact test.
Up to 3-4 months after cryosurgery
Specificity - Ability of contrast-enhanced ultrasound to successfully evaluate the cryoablation of renal cell carcinoma
Time Frame: Up to 3-4 months after cryosurgery
Specificity will be calculated for the contrast-enhanced ultrasound exam using both the standard of care contrast-enhanced CT or MRI, and patient outcome as the reference standard. Correlations between these findings and both contrast-enhanced MRI or CT findings and patient outcomes will be compared using the Fisher exact test.
Up to 3-4 months after cryosurgery
Accuracy - Ability of contrast-enhanced ultrasound to successfully evaluate the cryoablation of renal cell carcinoma
Time Frame: Up to 3-4 months after cryosurgery

Correlations between these findings and both contrast-enhanced MRI or CT findings and patient outcomes will be compared using the Fisher exact test.
