Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Experimental: Local ablative therapies (LAT) arm - A maximum of three Local ablative therapy (LAT) modalities can be administered for each participant, with a maximum of 2 modalities per organ, provided all LAT can be delivered within 12 weeks and participant can safely resume systemic treatment within 16 weeks from randomisation.

After completing LAT, participant is to resume a further two to three months of first-line systemic treatment to a total of 6 months (including the initial 3-4 months of treatment). For patients receiving a doublet or triplet regimen, treatment may be de-escalated to maintenance fluoropyrimidine +/- biologics or anti-EGFR monotherapy at any point after trial entry at clinician discretion. The treating clinician may choose to discontinue systemic treatment following LAT for patients who have experienced prior intolerable toxicity.

Outcomes

Eligibility
Key inclusion criteria
* Metastatic colorectal adenocarcinoma that is not amenable to potentially oncological curative surgery alone.
* Primary tumour must be controlled if the primary is intact, with no evidence of progression at primary site prior to study entry
* Imaging demonstrating ongoing treatment benefit (partial response or stable disease as per RECIST criteria) after 3-4 months of standard first-line systemic treatment.
* At least one metastatic lesion detected on CT +/- FDG-PET scan prior to first line systemic treatment AND on screening FDG-PET and CT scans, meeting the following criteria:

1. max of 3 lesions per organ except for the liver and lung
2. max of 5 lesions in the lung
3. no limitation to the number of liver lesions provided they are all amenable to LAT
4. max of 3 involved organs including a lymph node station
5. only one lymph node station involvement is allowed
6. for patients with liver metastases, a quadruple phase contrast enhanced CT or MRI liver is required to fully stage the liver; this can be performed prior to or within 4 weeks of commencing first line systemic treatment
7. staging FDG-PET scan is encouraged and can be performed prior to or within 4 weeks of commencing first line systemic treatment
* All lesions can be safely treated by LAT as determined by multidisciplinary team meeting.

Summary
Brief summary
This study aims to assess the clinical benefit of local ablative therapy (LAT) following initial standard first-line systemic treatment including the impact on survival, compared to continued standard first-line systemic treatment for oligometastatic colorectal cancer.
