Optimal use of anti-EGFR monoclonal antibodies for patients with advanced colorectal cancer: a meta-analysis.

ABSTRACT: This meta-analysis was performed to determine the optimal use of anti-EGFR mAb in the treatment of metastasized colorectal cancer (mCRC). Seventeen randomized clinical trials were included, all evaluating the added value of anti-EGFR mAb to standard treatment line in patients with KRAS wild-type mCRC. Hazard and odds ratios were pooled using a random effect model, weighted according to cohort size. Pooled data of six first- and two second-line studies demonstrated a significantly improved ORR (OR 1.62, CI 1.27-2.04; OR 4.78, CI 3.39-6.75, respectively) and PFS (HR 0.79, CI 0.67-0.94; HR 0.80, CI 0.71-0.91, respectively) with the addition of anti-EGFR mAb to chemotherapy, while OS remained similar. Two third-line anti-EGFR mAb monotherapy studies revealed an improved PFS and OS (HR 0.44, CI
