e14542 Background: Cetuximab (CTX) has demonstrated improved survival outcomes in metastatic colorectal cancer (mCRC) but information from real-life use is sparse. Here, CTX survival and safety outcomes in real-life are compared to those observed in OPUS and CRYSTAL trials. Methods: EREBUS is a French multicenter cohort study that included over two years (2009-2010) patients with unresectable mCRC and wild-type KRAS initiating CTX as 1st-line therapy in 65 centres and followed for 12 months from treatment initiation. Results: We included 389 patients treated with a combination of CTX with irinotecan-based (56.0%) or CTX with oxaliplatin-based (37.8%) chemotherapy. The main characteristics, safety, response rate, and one year survival of this cohort are presented in the Table below in parallel with results obtained in pivotal trials. Conclusions: Despite differences in baseline characteristics between real-life and pivotal trials (such as ECOG status), the response rate and PFS were comparable in mCRC patients with wt KRAS treated with 1st-line CTX. The nature of adverse events was in-line with the trials but the frequency was lower probably owing to under-notification in real-life. [Table: see text]
