Contrast-Enhanced Ultrasound for the Prediction of Bile Duct Cancer Response to Radioembolization Treatment

Description

This phase II trial tests whether contrast-enhanced ultrasound can predict the response of bile duct cancer to targeted radiotherapy (radioembolization treatment). Contrast-enhanced ultrasound uses gas microbubbles that may provide enhancement on ultrasound. It is also possible to pop these microbubbles using ultrasound imaging. Tumors that experience popping of these microbubbles may be easier to kill with radiotherapies. Therefore, this trial may also help doctors see if ultrasound-triggered microbubble popping can improve bile duct cancer response to radiotherapy. Another purpose of this trial is to test if the pressure inside the tumor estimated through ultrasound can be used to predict the tumor response to radiotherapy.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

For general information about clinical research, read Learn About Studies.

Eligibility Criteria

  • * Be scheduled for sub-lobar radioembolization therapy of a previously untreated intrahepatic cholangiocarcinoma greater than 1 cm but small enough to be fully visualized in the ultrasound three-dimensional (3D) volume (approximately 6 cm maximum diameter, but depth dependent)
  • * Be at least 18 years of age
  • * Be medically stable
  • * If a female of child-bearing age, have a negative pregnancy test prior to each ultrasound exam
  • * Have signed Informed Consent to participate in the study
  • * Females who are pregnant or nursing
  • * Patients with recent cerebral hemorrhage
  • * Patients with known sensitivities to albumin, blood, or blood products
  • * Patients with known hypersensitivity to perflutren
  • * Patients with known congenital heart defects
  • * Patients with severe emphysema, pulmonary vasculitis, or a history of pulmonary emboli
  • * Patients with bilirubin levels \> 2 mg/dL
