The Impact of Microsatellite Instability Status and Sidedness of the Primary Tumor on the Effect of Cetuximab-Containing Chemotherapy in Patients with Metastatic Colorectal Cancer.

ABSTRACT: Background: Colorectal cancer (CRC) has been reconsidered as a heterogeneous disease. Among advances of genomic analysis in CRC, the sidedness of tumors (left-sided colon vs. right-sided colon) and microsatellite instability (MSI)-high (H) tumors have been highlighted. Methods: We analyzed 153 CRC patients who were available for evaluation of MSI status and had been treated with cetuximab-containing chemotherapy between April 2008 and January 2013. KRAS mutational status was available in all 153 patients, but BRAF mutational status was only available in 72 patients (47.1%). We evaluated the impact of microsatellite instability status and location of the primary colon tumor on the effect of cetuximab-containing chemotherapy in patients with metastatic colorectal cancer.
