Brief Summary

For patients with initially resectable colorectal cancer liver metastases who have high-risk factors, neoadjuvant therapy is currently considered a consensus approach. However, there is ongoing debate regarding the optimal treatment strategy. Our study aims to investigate whether the addition of cetuximab to neoadjuvant chemotherapy improves outcomes compared to neoadjuvant chemotherapy alone. The objective of this phase III clinical trial is to determine whether the combination of cetuximab and mFOLFOX6 chemotherapy is superior to neoadjuvant mFOLFOX6 chemotherapy alone for patients with initially resectable colorectal cancer liver metastases who have wild-type RAS/BRAF and high-risk factors.

Conditions

Study Arms (2)

mFOLFOX6 + Cetuximab

EXPERIMENTAL

Cetuximab + mFOLFOX6: Cetuximab (500mg/m2 IV ) will be given. Oxaliplatin (85 mg/m2 IV over 2 h on day 1), Leucovorin calcium (350 mg/m2 IV over 2 h on day 1) plus a bolus of 5FU (400 mg/m2) followed by a 46h-48h IV infusion of 5FU 2400 mg/m2 will be repeated for every 2 weeks. The regimens repeat every 2 weeks for up to 4 courses in the absence of disease progression or unacceptable toxicity.
