Summary

This is a study to assess the motion of pancreatic tumors during radiation therapy using Computed Tomography (CT) Scans and an Active Breathing Control (ABC) Device.

United States No locations recruiting
Other countries No locations recruiting

Study Design

Observational model cohort
Time perspective prospective
Arm
Patients undergoing standard of care radiation treatment with Active Breathing Control (ABC)
standard radiation therapy
Radiotherapy will be planned and delivered according to institutional standard of care.
active breathing control device (abc)
computed tomography scan (ct)

Primary Outcomes

Measure
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
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

Secondary Outcomes

Measure
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
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

Eligibility Criteria

All participants at least 18 years old.

Inclusion Criteria: - Patients ≥ 18 years of age - A working diagnosis (with or without histologic confirmation) of pancreatic cancer - A plan to treat with radiotherapy (or chemoradiotherapy) - Patients must have fiducial marker(s) endoscopically placed within the pancreas for clinical treatment. Exclusion Criteria: - Previous abdominal radiotherapy. - Patients with a history of major abdominal surgery. - Patients who are pregnant.
