Design outcomes

Primary

MeasureTime frame
Secondary Objective: Secondary aims include investigating molecular biological response to chemotherapy, cost effectiveness, quality of life in patients tested for circulating tumour-marker positivity. ;Primary end point(s): Rate of patients free from recurrent CRC at 2 years post local treatment;Timepoint(s) of evaluation of this end point: August 2026;Main Objective: The primary aim of the present study is thus to investigate – in a randomized trial – the clinical utility of circulating tumor DNA analysis to guide treatment decisions in oligometastatic colorectal cancer.

Secondary

MeasureTime frame
Secondary end point(s): • Rate of grade 3-5 toxicity 6 months post-treatment • Molecular biological response to therapy after 6 months • Molecular biological DFS at 1 year • Time to molecular biological recurrence • Time to radiological recurrence • Local and distant relapse • Overall survival • QoL (EORTC QLQ – C30 and – CR29) and questionnaires for patients preferences • Cost effective analysis Definition of endpoint • Molecular biological response is defined as lack of detectable tumour DNA in plasma samples • Time to molecular biological recurrence is calculated from first time of no detectable DNA until de-tectable DNA in a samples • DFS is defined as the time from inclusion to the first clinical event of local relapse, distant relapse or death • Overall survival is defined as the time from inclusion to death from any cause. ;Timepoint(s) of evaluation of this end point: August 2029
