Patients with colorectal cancer liver metastases were RAS wild type, received first-line cetuximab plus chemotherapy. After first-line progression, second-line non-cetuximab treatment were used. After second-line progression, ctDNA is test, and patients with RAS wild-type are enrolled in the study to compare cetuximab plus chemotherapy vs. chemotherapy alone as third-line treatment. Treatment will continue until disease progression or unacceptable toxic effects. The primary endpoint is the disease control rate?which will be assessed by local multidisciplinary team with the use of contrast-enhanced CT or MRI after 4 cycles and then every other 4 cycles up to 12 cycles.
