Obvious differences in differentiation degree, FIGO stage, infiltration depth, and lymph node metastasis were shown between patients with PD-L1 coupled with high-density of CD8+ TILS and those with PD-L1 coupled with low-density of CD8+ TILS (P < 0.05). Here, CD274 is linked to metastatic malignant neoplasm in the lymph nodes.
