Abstract Objective: To investigate the expression of PD-L1 in colorectal cancer and its relationship with clinicopathologic features, and meanwhile to discuss the clinical significance of PD-L1 expression. Methods:Colorectal cancer tissues and adjacent normal tissues were obtained from 50 patients with colorectal cancer. RTPCR and Western blot were conducted to detect the expression of PD-L1 in mRNA and protein levels. Results:The expression of PD-L1 in colorectal cancer tissues was elevated, compared with that in adjacent normal tissues (P<0.05). The elevated expression of PD-L1 in colorectal cancer tissues was correlated with cancer differentiation degree and lymphatic metastasis (P<0.05). Conclusion: PD-L1 was highly expressed in colorectal cancer patients, which was correlated with the clinicopathologic features.
