Feasibility and safety of single-fraction sub-ablative radiotherapy with systemic therapy in colorectal cancer patients with ≤ 10 metastases: A multicenter pilot study (NCT05375708)

Colorectal cancer patients with ≤10 unresectable metastases were treated with single-fraction sub-ablative radiotherapy in addition to standard of care systemic therapy in a single-arm, open-label, multicenter, pilot study (SIRIUS) to assess feasibility and safety. Results indicate that radiotherapy combined with systemic therapy is feasible and safe in this population.
