Subgroup analysis based on tumor sidedness in KRAS wt and KRAS mt CC patients showed that in left‐sided CC, RFS of KRAS mt patients with a sequential pattern were better compared with those with a skipped pattern (Figure 5A (wt), P = .34 in left‐sided and Figure 5B (wt), P = .43 in right‐sided; Figure 5C (mt), P = .001 in left‐sided and Figure 5D (mt) P = .51 in right‐sided). Here, KRAS is linked to neoplasm.
