KRAS and colonic neoplasm: So far, we have identified a higher incidence of mutations in non-dHGP patients and inability to fully resect the liver tumors (p = 0.0375, Table 4) and a higher incidence of KRAS mutations in patients with right-sided colon tumors (p = 0.0241 and p = 0.0197, Supplementary Table S3) and an association of PIK3CA mutations with right-sided primary tumors (p = 0.0139, Supplementary Table S3).
