Clinical summary

Summary

Eligible participants will be randomly allocated to either the local ablative therapy (LAT) arm, or the control arm. In the LAT arm, participants will receive metastasis-directed LAT such as radiation therapy or thermal ablation following initial standard first-line systemic treatment. In the control arm, participants will receive continued first-line systemic treatment alone. Those receiving LAT will return to systemic treatment 16 weeks post-randomisation.

Conditions

This trial is treating people with metastatic colorectal cancer

Eligibility

Inclusion

-Metastatic colorectal adenocarcinoma that is not amenable to potentially curative surgery.
-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.
-3 to 10 metastatic lesions detected on CT +/- FDG-PET scan prior to first line systemic treatment AND on screening FDG-PET and CT scans:
o maximum of 3 lesions per organ except for the liver.
o maximum of 3 involved organs including a lymph node station.
o only one lymph node station involvement is allowed.
-All lesions can be safely treated by LAT as determined by multidisciplinary team meeting.

Exclusion

-Concurrent or previous other malignancy within 2 years of study entry, except curatively treated basal or squamous cell skin cancer, prostate intraepithelial neoplasm, carcinoma in-situ of the cervix, Bowen’s disease or prostate cancer with a Gleason score =6.
-Presence of brain, peritoneal, omental or ovarian metastases
-Malignant pleural effusion or ascites.
