Primary Outcome Measures
NameTimeMethod
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 Outcome Measures
