The Relationship between SNP-216 or CA-SSR1 Polymorphism and the Efficacy of EGFR-TKIs according to EGFR Mutation Status

TKI, tyrosine kinase inhibitor; SNP, single nucleotide polymorphism; CA-SSR1, CA simple sequence repeat in intron 1; EGFR, epidermal growth factor receptor; RR, response rate; DCR, disease-control rate.

^*p values were obtained by comparing between EGFR mutation and SNP-216 or CA- SSR1 polymorphism using the chi-square or Fisher's exact test (expected cell value <5). Data in the '( )' represent the p values by comparing the EGFR mutation negative and positive group.
