Age
18 Years to No maximum

Inclusion criteria

Inclusion criteria: • histologically confirmed solid malignancy with metastatic disease detected on imaging. Biopsy confirmation of metastatic disease is preferred but not required • one to ten extracranial active tumor lesions on recent imaging • local radiotherapy is clinically indicated and scheduled according to one of the INTERACT schemes • ECOG 0/1 • age =18 years • able and willing to provide informed consent

Exclusion criteria

Exclusion criteria: • serious medical comorbidities precluding ablative radiotherapy • substantial overlap of disease sites with a previously treated radiation volume that precludes meeting dose constraints in a composite plan • malignant meningitis • pregnant or lactating individuals • patient’s refusal to participate

Design outcomes

Primary

MeasureTime frame
The registry's objectives include descriptive analysis of outcomes after SBRT and enrichment of the analyses of the planned randomized arms in the planned, randomized INTERACT Trial. Translational studies include radiomics and liquid biomarkers.

Secondary
