The expression of PD-L1 could be a novel biomarker which predicts that patients are more likely to respond to immunotherapy. Our study investigated the relationship among clinicopathological characteristics, prognosis, PD-L1 expression levels, and FOXP3 Treg infiltration. In addition, the relationship among clinicopathological characteristics, prognosis, PD-L1 expression levels, and FOXP3 Treg infiltration was explored. Furthermore, the relationship between PD-L1 expression and FOXP3 Treg infiltration was examined. We found that 41.3% of pancreatic cancer patients had PD-L1-positive staining; both PD-L1 expression levels and FOXP3 Treg infiltration were significantly associated with depth of invasion, lymph node metastasis, distant metastasis, and pTNM. In addition, PD-L1 expression and FOXP3 Treg infiltration also could be prognostic biomarkers for pancreatic cancer.
PD-L1 的表达可能是一种新的生物标志物，可预测患者更有可能对免疫治疗产生反应。我们的研究调查了临床病理特征、预后、PD-L1 表达水平和 FOXP3+Treg 浸润之间的关系。此外，还探讨了临床病理特征、预后、PD-L1 表达水平和 FOXP3+Treg 浸润之间的关系。此外，还研究了 PD-L1 表达与 FOXP3+Treg 浸润之间的关系。结果发现，41.3%的胰腺癌患者存在 PD-L1 阳性染色；PD-L1 表达水平和 FOXP3+Treg 浸润均与浸润深度、淋巴结转移、远处转移和 pTNM 显著相关。此外，PD-L1 表达和 FOXP3+Treg 浸润也可能是胰腺癌的预后生物标志物。
