4D-CT for Pancreatic Adenocarcinoma in Radiotherapy Simulation (GCC 1210)

March 16, 2020 updated by: Department of Radiation Oncology, University of Maryland, Baltimore

Individually Optimized Contrast-Enhancement 4D-CT for Pancreatic Adenocarcinoma in Radiotherapy Simulation

The primary objective is to study the feasibility and efficacy of individually optimized CE 4D-CT for PDA in radiotherapy simulation.

Conditions

Intervention / Treatment

Detailed Description

Compared with current clinical practice, the individually optimized CE 4D-CT can potentially provide much improved tumor-to-parenchyma conspicuity of pancreatic adenocarcinoma. This will help the radiation oncologists or radiologists to contour the tumor with higher precision and confidence, and compute the tumor volume and tumor motion more accurately.

Description

Inclusion Criteria:

  1. Patients 18 years old or older
  2. Patients with PDA who have not had surgical removal of their tumor and who are planned for treatment with radiotherapy in the Radiation Oncology Department at the University of Maryland.
  3. Patients who have signed the contrast consent form and have been recommended by physicians to have contrast-enhanced CT scans.
  4. Patients who have signed the consent form for this study

Exclusion Criteria:

  1. Pregnant or breast-feeding women.
  2. Patients with severely decreased renal function19-21.
  3. Patients with known severe allergic reactions to contrast.
  4. Patients who have difficulty lying flat on their back for extended periods of time.
  5. Patients with breaths per minute (BPM) rate less than 10, due to the limitation of 4D-CT image reconstruction software.

Design Details

Cohorts and Interventions

Group / Cohort
Intervention / Treatment
All enrolled patients
Contrast-enhanced 4D computed tomography
Other: Contrast-enhanced 4D computed tomography
All enrolled patients each underwent three CT scans: a 4DCT immediately following a contrast-enhanced 3DCT and an individually optimized contrast-enhanced 4DCT.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Individually Optimized Contrast-enhanced 4DCT for Radiotherapy Simulation
Time Frame: 1 year
Image quality (anatomic details, motion artifacts, beam hardening and enhancement of pancreatic tissue and tumor were scored from 1 to 5, with 1 being very poor and 5 being excellent), CT number of pancreas and tumor, tumor-to-pancreas contrast, image noise and contrast-to-noise ration (CNR) were compared among contrast-enhanced (CE) 4DCT, CE 3DCT and 4DCT without contrast enhancement.
