High expression of PD‐L1/PD‐L2 was closely associated with high accumulation of 18F‐FDG. Angiogenetic markers were linked to the expression of PD‐L1/PD‐L2. PD‐L1 and PD‐L2 exhibited a close relationship with upregulation of tumor glucose metabolism and hypoxia. The gene discussed is CD274; the disease is neoplasm.
