The positive correlation between PD‐L1 and CD8 found in this study has also been observed in other studies related to other types of cancer, such as non‐small cell lung cancer [22], intrahepatic cholangiocarcinoma [23], intestinal gastric adenocarcinoma, invasive breast carcinoma of no special type, and liposarcoma [24]. Here, CD274 is linked to gastric intestinal type adenocarcinoma.
