PD-L1检测方法在非小细胞肺癌的研究进展

PD-1/PD-L1 inhibitors play an important role in the first-line and second-line treatment of non-small cell lung cancer (NSCLC), indicating a new treatment strategy of NSCLC. Completed clinical trials have shown that effective detection of PD-L1 expression is the key to the use of immunosuppressive agents. However, the gold standard for PD-L1 detection has still lacked. In recent years, immunohistochemistry (IHC) and enzyme-linked immunosorbent assay (ELISA) have been continuously innovated, which accounts for good prospect in PD-L1 detection. The research progress of PD-L1 detection methods in NSCLC is summarized in this review.
