Locally ablatIVe thErapy for oLigo-progressive gastrOintestiNal maliGnancies (LIVELONG)

This is a phase 2 pragmatic study at a single site that evaluates the clinical benefit of continuing systemic therapy with the addition of locally ablative therapies for oligo-progressive solid tumors as the primary objective. The primary endpoint is disease control at 3 months, defined as continuation in systemic cancer therapy without any changes or permanent discontinuation for 3 months following first day of ablative local therapy. Participants will receive ablative local therapy per standard practices in addition to their systemic therapy and will be followed for up to 5 years following ablative local therapy. Participants will be assigned stereotactic ablative radiotherapy (SABR) or interventional radiology (IR) ablation therapy per the discretion of treating radiation oncologist and/or interventional radiologist.
