Higher PD-L1 positive expression rate was shown in patients with FIGO stages III to IV, tumor diameter ≥ 3 cm, deep muscle invasion, poor differentiation, lymph node metastasis, and vascular invasion of cervical cancer patients in cervical cancer tissue, compared with that in patients with FIGO stages I to II, moderate and high differentiation, tumor diameter < 3 cm, superficial infiltration of the muscle layer, nonmetastasis of the lymph node, and vascular invasion, implying that PD-L1 positive expression had a connection with the increased tumor infiltration. This evidence concerns the gene CD274 and neoplasm.
