PANCREATIC CANCER CT IMAGING: COMPARISON WITH SURGERY.
Summary
Optimizing computed tomography (CT) protocols improves pancreatic cancer staging. Specific imaging phases and criteria accurately assess vascular invasion, aiding in treatment decisions for pancreatic cancer.
Area of Science:
- Radiology
- Oncology
- Medical Imaging
Background:
- Pancreatic cancer diagnosis and staging are critical for effective treatment.
- Accurate assessment of tumor extent, particularly vascular invasion, remains a challenge in pancreatic cancer imaging.
- Computed tomography (CT) is a key imaging modality for evaluating pancreatic cancer.
Purpose of the Study:
- To establish an optimized computed tomography (CT) protocol for pancreatic cancer.
- To define precise criteria for staging pancreatic cancer, focusing on vascular invasion.
- To evaluate the effectiveness of CT in depicting tumor extension and metastases.
Main Methods:
- A CT protocol was developed including non-enhanced CT, pancreatic phase, and portal venous phase imaging.
- 49 consecutive patients with pancreatic cancer were examined using a Siemens 16 Emotion CT unit.
- Evaluation included tumor extension into surrounding fat, organs, and vessels, as well as lymphadenopathy and distant metastases.
Main Results:
- The most affected age group was 60-79 years.
- CT identified varying stages of pancreatic cancer (T3 and T4), with 5 cases showing extension into adjacent organs.
- Vascular invasion criteria were established: >50% arterial circumference contact for arteries, and deformity/thrombosis for veins. Lymphadenopathy and distant metastases were also assessed.
Conclusions:
- Computed tomography (CT) is effective for pancreatic cancer examination when appropriate protocols are used.
- The pancreatic phase is optimal for visualizing arteries and the tumor, while the portal venous phase excels at depicting liver metastases.
- Established criteria for vascular invasion (arterial contiguity, venous deformity/thrombosis) improve staging accuracy, with CT staging often underestimating compared to surgical staging.
