What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Distance traveled by the pancreatic tumor during radiation treatment using Computed Tomography (CT) Scans and an Active Breathing Control (ABC) Device
Time Frame: Weeks -3 to -1, Week 1, Week 3, Week 5
|
A marker (implanted near the radiation site, prior to treatment, as a point of reference) will be noted in space on an x, y and z plane using a CT scan.
The excursion of this marker during treatment will be determined and the distance traveled, as well as the overall vector (distance and magnitude), will be calculated.
Later scans will assess changes in the ability to calculate distance traveled and overall vector of travel.
|
Weeks -3 to -1, Week 1, Week 3, Week 5
|
Distance traveled by the pancreatic tumor between radiation treatments using Computed Tomography (CT) Scans and an Active Breathing Control (ABC) Device
Time Frame: Week -3 to -1, Week 1, Week 3, Week 5
|
A marker (implanted near the radiation site prior to treatment as a point of reference) will be noted in space on an x, y and z plane on a pre-treatment/planning Computed Tomography (CT) scan.
The relative position of the marker on later CT scans will be compared to the pre-treatment/planning scan and the difference in position will be calculated.
The change in the position between all CT scans will be calculated for statistical analysis of tumor movement while undergoing treatment with an Active Breathing Control (ABC) Device.

Week -3 to -1, Week 1, Week 3, Week 5

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Probability of surrounding normal tissue being a particular distance from the tumor marker at any time point.
Time Frame: Week -1 to -3, Week 1, Week 3, Week 5
|
Week -1 to -3, Week 1, Week 3, Week 5
|
|
Assess the impact of the determined treatment margins on the radiation dose to normal tissues and the ability to escalate dose to the tumor using Intensity-Modulated Radiation Therapy (IMRT)
Time Frame: Analysis will take place after treatment at approximately week 6
|
To assess the impact of the determined treatment margins on radiation dose distribution, we will retrospectively recalculate the patient's treatment plan based on the measured motion of the tumor and normal tissue.
This new treatment plan will be compared with the original treatment plan.
If the new treatment plan suggests normal tissue was exposed to a reduced amount of radiation, multiple treatment plans will be generated to assess the extent to which this reduction will allow for increased tumor dose in the future.

Analysis will take place after treatment at approximately week 6
