[0029] The technical scheme of the present invention is further described below in conjunction with experiments.
[0030] case screening
[0031] The inventors selected 247 patients as a sample of patients initially diagnosed with gastric cancer. During subsequent treatment, 34.4% (83 patients) died during the follow-up period.
[0032] ELISA detection of PDL1
[0033] PDL1 levels in serum of GC patients were detected by PDL1 ELISA kit (WEA788Hu-96T), which was purchased from Cloud Clone Company (CCC, Wuhan, China). For specimen collection, 3 ml of blood was collected from a blood collection tube containing EDTA-K2 anticoagulant, and centrifuged at 3000 r / min for 5 min at room temperature. ELISA Test Plasma specimens and ELISA kit were placed at room temperature in advance, and the operation was strictly in accordance with the instructions of the ELISA kit.
