Figure 4. LCS6-variant patients do not have improved OS with the addition of chemotherapy for double wt patients.
(A) Median OS according to the KRAS 3′-UTR LCS6 SNP genotype status in the double (KRAS and BRAF) wt patients’ population treated with anti-EGFR moAbs monotherapy as salvage treatment. (B) Median OS according to the KRAS 3′-UTR LCS6 SNP genotype status in the double (KRAS and BRAF) wt patients’ population treated with anti-EGFR moAbs based combination chemotherapy as salvage treatment. (C) Median OS according to type of therapy in the double (KRAS and BRAF) wt KRAS 3′-UTR LCS6 SNP carriers. (D) Median OS according to type of therapy in the double (KRAS and BRAF) wt non-KRAS 3′-UTR LCS6 SNP carriers.
