CD274 and neoplasm: Stromal PD-L1 positivity were significantly associated with less aggressive tumor features, including early pathological T stage (p < 0.001), absence of lymph node metastasis (p = 0.031), absence of tumor deposit (p = 0.012), early TNM Stage (p = 0.034), less tumor budding (p = 0.039), and less bowel perforation (p < 0.001).
