What this trial is trying to do
The trial asks whether stereotactic body radiation therapy (SBRT)—a few highly focused, high-dose radiation treatments—can control liver metastases that remain potentially treatable after chemotherapy and, for rectal cancer, short-course radiation. The planned sequence is chemotherapy, reassessment, SBRT to the liver lesion, and surgery for the primary rectal tumour when appropriate.
The researchers expect this less invasive approach could cause less treatment-related illness and preserve quality of life compared with surgery or other local treatments, while delaying cancer growth; the main measure is progression-free survival, not overall survival. The trial is also testing whether this treatment pathway is feasible in people whose disease has not progressed after initial treatment.
Worth knowing: This is a small, non-randomised phase 2 feasibility trial, so it has no comparison group and cannot establish whether SBRT is better than surgery or improves survival.
Written from the trial's own registry entry to explain what the researchers are testing and why. Nothing here is a result — this trial has not reported one — and it is not a view on whether the treatment works or on whether it would suit you.

What is being tested
- Radiotherapy stereotactic body radiation treatment (SBRT)
What it is measuring
Progression free survival (PFS)
This is the trial's main question — the one it is designed and sized to answer. Anything else it reports is a secondary finding, and secondary findings are far more likely to be chance.
Phase 2. Tests whether the treatment works well enough to be worth a larger trial. Usually too small to prove it changes survival.
How the researchers describe it
This will be a phase II feasibility trial to evaluate ablative radiation for the management of colorectal cancer with potentially resectable/ablatabale synchronous oligo-metastases.
In this study, following completion of the neo-adjuvant component of treatment, patients will be re-staged (as is the current standard of care) and can then proceed for SBRT to the liver lesion. Patients who may have responded very well to the systemic treatment with no-residual disease on re-staging imaging, will use pre-treatment imaging for target delineation. The advantage of SBRT is in the minimally invasive approach to treatment that may be associated with lower morbidity, better quality of life and post treatment morbidity, as well as being significantly less expensive.
The planned course of the neo-adjuvant component of treatment for this study will reflect the NCCN (National Comprehensive Cancer Network) guidelines and will treat rectal cancer patients with a short course of radiation followed by 6-9 cycles of a combination chemotherapy regimen.
For the colon cancer group of patients, all patients will receive 6-9 cycles (2-3 months) of neo-adjuvant systemic chemotherapy as per current standard of care.
Patients with non-progressive disease at that point, will have SBRT for the metastatic lesion followed by surgery for the primary rectal cancer.

Who the trial is looking for
Inclusion Criteria
- Age ≥ 18 years
- ECOG (Eastern Cooperative Oncology Group) 0-2
- Able to provide written informed consent
- 1-5 Liver lesions with max size of ≤5cm for a single lesion and restricted to one lobe of liver; deemed at Multi-Disciplinary Tumor Board (MDT) to be potentially amenable for SBRT with curative intent
- Liver lesion identified within 3 months of diagnosis of primary and deemed at Multi-Disciplinary Tumor Board (MDT) to be potentially amenable for SBRT with curative intent
- Plan for resection of primary with curative intent
- Patients with liver metastases and potentially resectable/ablatable lung mets can be included.
- Colon cancer patients who have undergone upfront resection of primary colonic lesion can be included
- Able and willing to comply with the terms of the protocol including health-related quality of life (HRQoL) questionnaires
- Women of child bearing potential (WOCBP) must have a negative serum (or urine) pregnancy test at the time of screening. WOCBP is defined as any female who has experienced menarche and who has not undergone surgical sterilization (hysterectomy or bilateral oophorectomy or bilateral salpingectomy) and is not postmenopausal. Menopause is defined as 12 months of amenorrhea in a woman over age 45 years in the absence of other biological or physiological causes.

Worth asking your oncology team
Being listed here is not a recommendation, and no one page can tell you whether a trial is right for you. These are the questions it raises.
- Is this trial open at a hospital I could realistically travel to?
- Given my stage, my previous treatment and my tumour's molecular profile, would I be eligible?
- What would I be giving up by joining — is the comparison arm the treatment I would otherwise be having?
- What is already known about the safety of what is being tested?
