Testing Treatment plan for advanced cancer
Official title: Simulation-Free Celiac Plexus Pain Ablation Using Stereotactic Body Radiotherapy in Patients With Cancer-Related Celiac Pain
A Prospective Pilot Clinical Trial of Simulation-Free Celiac Plexus Pain Ablation Using Stereotactic Body Radiotherapy in Patients With Cancer-Related Celiac Pain
- 1 group
- One site, in Toronto

Interventions
- Other intervention
Treatment plan
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.

Eligibility Criteria

The trial’s own eligibility text, word for word from the registry. Only the trial site can say who takes part.
Inclusion
- +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.
- +Subjects must have the ability to understand and the willingness to sign a written informed consentInformed consentThe process of being told what taking part involves, then choosing freely.Read more → document.
- +Subjects must have a diagnostic CT of the abdomen and pelvis, with or without contrast, acquired \< 28 days prior to the study consent.
- +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.

About This Trial
This is a prospective, single-arm, pilot feasibility clinical trial designed to evaluate the feasibility and safety of a simulation-free adaptive radiotherapy workflow to enable single-session celiac plexus SBRT planning and delivery. In this trial, the treatment itself is non-investigational (standard-of-care celiac plexus SBRT) but the treatment workflow (simulation-free, using adaptive radiotherapy to compress treatment planning and delivery into a single session) is novel. Investigators hypothesize 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.
