설명
Inclusion Criteria:
- Subjects must have histologically or cytologically confirmed cancer that is metastatic or unresectable, and considered appropriate per the treating physician to receive celiac plexus SBRT.
- Age >18 years. Because no data are currently available on the use of celiac axis SBRT in subjects ≤18 years of age, children are excluded from this study.
- Performance status: ECOG Performance status ≤ 3
- Severe retroperitoneal pain syndrome (radiates from the lower back to the upper abdomen, belt- like distribution), intensity of at least 5 on 11-point Brief Pain Inventory (BPI, average pain) scale.
- Subjects must have anatomical involvement of the celiac plexus on the diagnostic CT, PET/CT, or MRI. This includes: Any pancreatic cancer, any other cancer that on imaging demonstrates either gross involvement of the celiac blood vessels or celiac plexus on imaging OR haziness around the celiac blood vessels that typically implies tumor engulfment.
- Prior chemotherapy or biological treatment is allowed, but any active oncological treatment should be stopped at least 1 week prior to radiation therapy and renewed at least 1 week following radiation therapy.
- Subjects must have the ability to understand and the willingness to sign a written informed consent document.
- Subjects must have a diagnostic CT of the abdomen and pelvis, with or without contrast, acquired < 28 days prior to the study consent.
Exclusion Criteria:
- In ability to tolerate lying supine and still for at least 45 minutes.
- Performance status: ECOG Performance status of 4.
- Previous radiotherapy to the upper abdomen overlapping with the projected site of treatment.
- Pregnant or breastfeeding women are excluded from this study.
- Subjects with conditions associated with increased risk of side effects from radiation such as inflammatory bowel disease and scleroderma.
- Women of childbearing potential must have a negative pregnancy test within 14 days of study entry. If pregnancy test is not clinically indicated as determined by treating physician or protocol principal investigator, documentation of this exception is sufficient in lieu of a pregnancy test.

실험적: Sim-free ART workflow
|
Simulation-free radiation treatment planning, in which pre-existing diagnostic images are used to generate a radiation treatment pre-plan (as opposed to acquiring planning-specific image sets).
This will be paired with the use of online adaptive radiotherapy (ART) to refine the pre-plan to create a final plan that matches the on-table internal target and gastrointestinal anatomy observed with on-board imaging on the day of treatment.
This enables single-session celiac plexus SBRT planning and delivery.

Successful treatment plan workflow of 80% of patients
기간: 1 year
|
The feasibility and safety of the simulation-free adaptive radiotherapy workflow for celiac plexus SBRT for clinical use. Feasibility defined as the successful completion of the simulation-free ART workflow through treatment delivery in the first on-table treatment attempt for at least 80% of patients. All of the following criteria must be met to be deemed feasible:

Component time
기간: 1 year
|
Average time required for each component of the simulation-free ART workflow, including but not limited to plan generation using diagnostic imaging, pre-treatment activities (e.g., on-table patient setup/imaging, dose prediction, segmentation of daily contours, plan optimization and evaluation), and treatment delivery.

|
Dosimetric comparison of radiation plans
기간: 1 year
|
Dosimetric comparison of radiation plans created on traditional offline CBCT images with those created using the simulation-free ART workflow (i.e., comparison of target coverage, sparing of organs-at-risk).
|
1 year
|
|
Frequency of online re-adaptation
기간: 1 Year
|
Frequency of online re-adaptation within the sim-free workflow.
Readaptation defined as the need to regenerate a treatment plan after an initial plan had been generated that does not satisfy treatment parameters.
|
1 Year
|
|
Patient satisfaction
기간: 1 year
|
Overall patient satisfaction with celiac plexus SBRT using a simulation-free, adaptive radiotherapy workflow.
This will be assessed using the Radiotherapy Experience Questionnaire (RTEQ) which is a validated RT experience questionnaire that reports patient experiences with the overall treatment process by answering statements on a scale of strongly agree to strongly disagree.
Given that this is a novel workflow/process, the results of the questionnaire will shed light on their overall experience.

Cost of workflow
기간: 1 year
|
The overall cost of simulation free workflow compared to select retrospective cases treated on conventional workflow.
Timepoints include simulation, planning, treatment, and follow up.
Components include planning, therapist, clinician.
