Secondly, same result was found in patients with acinar adenocarcinoma, i.e., high PD-L1 expression was significantly correlated to an adverse PFS (P < 0.001), but not to poor OS (P = 0.129) or PFS (P = 0.291) in patients with non-acinar adenocarcinoma (Figure 3). This evidence concerns the gene CD274 and acinar cell carcinoma.
