ABSTRACT
Monoclonal antibodies targeting epidermal growth factor receptor (EGFR) or vascular endothelial growth factor (VEGF) have showed clinical benefit in combination with chemotherapeutic cytotoxic drugs in the first-line therapy of metastatic colorectal cancer (mCRC). Data from randomized studies comparing these monoclonal antibodies as initial therapy is conflicting, and their comparative efficacy remains unknown. This study aimed to evaluate the impact of the combination of anti-epidermal growth factor receptor (anti-EGFR) therapy and anti-vascular endothelial growth factor therapy on mCRC patient outcomes by combining the data from randomized clinical trials. Three trials meeting the eligibility criteria, and four randomized studies were included in the meta-analysis. For MCRC patients with KRAS wild type (KRAS-WT), the ORR was superior in patients treated with anti-EGFR compared with those who treated with anti-VEGF therapy. This effect was even better for all RAS-WT patients. Progression-free survival (PFS) rates were not significantly different for KRAS-WT mCRC and all RAS-WT mCRC between the two groups. The overall survival (OS) was higher for RAS wild-type (RAS-WT) mCRC patients who received anti-EGFR, but the KRAS-WT patients compared to the anti-VEGF therapy. The results of our research indicate that superior ORR and OS between the addition of anti-EGFR therapy VS anti-VEGF therapy in all RAS-WT patients with MCRC. There was no significant difference in OS and PFS between the two groups for KRAS-WT mCRC. These results suggest that anti- EGFR monoclonal antibodies can achieve an equivalent efficacy when compared with anti-VEGF therapy of all RAS-WT mCRC patients.
