Relative to non-Sq NSCLC, the fraction of samples positive for high PD-L1 expression in KRASm CRC, PDAC, and endometrial was low (Fig. 4b), and relatively few ICC, SBA and appendiceal samples were tested for PD-L1 (Supplemental Table 4). The gene discussed is CD274; the disease is intrahepatic cholangiocarcinoma.
