The aim of this study is to explore the application of surface-enhanced Raman scattering (SERS) system in the diagnosis of benign and malignant lung cancer biopsy, and to promote the rapid diagnosis of lung cancer. In addition, the correlation between tumor PH value, PD-L1 expression detected by fluorescent probes and the efficacy and prognosis of immunotherapy was explored. Based on this, the immunotherapy efficacy and prognosis prediction models based on patients' clinical information, PD-L1 expression by immunohistochemistry, PD-L1 expression by fluorescent probes and PH value detected by SERS were constructed to promote the precision of tumor immunotherapy.
The aim of this study is to explore the application of surface-enhanced Raman scattering (SERS) technology and specific PD-L1 detection fluorescent probes in the clinical diagnosis and prognosis of lung cancer immunotherapy, and further promote the rapid diagnosis of lung cancer and the precision of tumor immunotherapy.
