Pilot study to evaluate the feasibility of measuring (a) intratumoral pressures using a novel piezo- resistive semiconductor catheter and (b) intratumoral stiffness using shear wave elastography with ultrasound
MD Anderson Study Status
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).
