IMPROVE ITChemotherapy for patients with circulating tumor DNA in the blood after surgery for bowel cancer

Primary objectives: The main clinical hypothesis is that patients having undergone radical resection from CRC do not present with detectable tumor DNA in the plasma, whereas patients with detectable tumor DNA two weeks’ post-surgery have residual microscopic disease, and consequently a high risk of diseases recurrence which can be prevented with adjuvant chemotherapy.
The primary aim of the present study is to investigate – in a randomized trial - if use of standard adjuvant chemotherapy therapy improves the disease free survival in patients with molecular biological residual disease where adjuvant chemotherapy is not standard treatment
Primary endpoints: • Disease free survival at 3 year
