Information provided by (Responsible Party):
University of Rochester
The purpose of this research study is to evaluate typical tumor motion caused by breathing using MRI and can help determine whether simple passive breathing and/or breath-holding could be used for the future treatment of similar lung and liver tumors using radiation therapy radiosurgery techniques.

Condition Intervention
Neoplasm, Metastatic Procedure: MRI with breath-holding

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Feasibility Study for Gated External-Beam Radiotherapy for Patients With Internal, Extra-cranial Tumors

Further study details as provided by University of Rochester:

Primary Outcome Measures:
  • Tumor Motion Related to Breathing as Determined From MRI Images [ Time Frame: 20 - 30 seconds ]
    1. Determine the typical and maximal tumor 3D displacements over the respiratory cycle and how these values vary depending on the tumor location
    2. Determine the reproducibility of target position over multiple breath-holds
    3. Determine the variability across patients in respiratory-derived lesion motion and target position reproducibility over multiple breath-holds

Enrollment: 10
Study Start Date: January 2002
Study Completion Date: January 2011
Primary Completion Date: January 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Breath-holding
MRI with breath-holding
Procedure: MRI with breath-holding
Breath holding for diminished tumor motion.
