An Investigational Device (Millar Mikro-Tip Catheter) and Imaging Scan (Shear Wave Elastography) in Measuring Tumor Pressure and Stiffness in Patients With Solid Tumors Undergoing Ultrasound-Guided Biopsy

United States27 participantsStarted 2015-12-29

Plain-language summary

This trial studies how well a Millar Mikro-tip catheter and shear wave elastography measure pressure and stiffness inside tumors among patients with solid tumors undergoing an ultrasound-guided biopsy. A Millar Mikro-tip catheter measures the pressure inside the tumor. Shear wave elastography is similar to an ultrasound and uses sound waves to vibrate the tissue in order to study tissue stiffness. These measurements may help doctors learn if pressure and stiffness are related to intratumoral fibrosis (the thickening and scarring of connective tissue).

Inclusion Criteria: * Patients who are scheduled for at least one biopsy (diagnostic or research) for solid organ tumors (excluding bone) at MD Anderson. * Patients who are able to understand and give consent to participation in the study. Exclusion Criteria: * Tumor size \< 1.5 cm or \> 5 cm in size on pre-procedural imaging for 1st assessment and \< 1 cm for 2nd assessment * Pregnant women (these patients will be tested for pregnancy before they are scheduled for a diagnostic or research biopsy per inclusion criteria #1). * Tumors involving bone.
