Endoscopic Ultrasound-Guided Fiducial Placement for Stereotactic Body Radiotherapy

EUS-Guided Fiducial Placement for Stereotactic Body Radiotherapy

The purpose of this research study is to evaluate placing the radiation therapy markers (Fiducial) by using an endoscopic procedure. The endoscopic procedure is called an Endoscopic Ultrasound (EUS). This is a procedure using a special endoscope that has an ultrasound on the end. The ultrasound will allow the doctor's to see where the radiation therapy markers (Fiducial) is to be placed as outlined by the Radiation Oncologist.

Inclusion Criteria:

• Age 18 years or older,
• Scheduled to undergo fiducial placement,
• Subject must be able to give informed consent

Exclusion Criteria:

• Any contraindication to performing endoscopy,
• Participation in another research protocol that could interfere or influence the outcomes measures of the present study,
• The subject is unable/unwilling to give informed consent
