CD274 and neoplasm: No differences in PFS and OS were seen in relation to PDL1 status and tumor molecular profile, with the exception of KRAS mutations; patients with KRAS-mutated disease had an mOS of 8 months (95%CI, 4.3–8.2–NE) compared to 38.8 months (95%CI, 13.9–NE) for those with KRAS wild-type tumors (Figure 4 and Tables 3, 4).
