RESOLUTE Trial Aims to Investigate the Value of Adding Local Ablative Treatment to Standard Systemic Treatment for Unresectable Oligometastatic Colorectal Cancer

LAT modalities allowed include surgical resection, stereotactic radiotherapy (SRT), laparoscopic or percutaneous thermal ablation \[radiofrequency ablation (RFA) or microwave ablation (MWA)\]. The LAT modalities will be delivered by specialists in the field (surgeons, radiation oncologists and/or interventional radiologists). The precise mode of delivery and number of times the LAT modality is delivered is case-dependent and is determined at a multi-disciplinary meeting (MDM).

Standard of care as determined by the treating clinician. The following standard chemotherapy regimens are allowed: single agent fluoropyrimidine, CAPOX, FOLFOX, FOLFIRI, CAPIRI or FOLFOXIRI. Treatment with a biologic is allowed including bevacizumab or an anti-EGFR antibody (cetuximab or panitumumab). 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.
