Immune and inflammation-related factors alteration as a biomarker for predicting prognosis and responsiveness to PD-1 monoclonal antibody in patients with recurrent cervical cancer

Purpose: We aimed to elucidate the potential mechanisms of effective responsiveness to PD-1 monoclonal antibody and evaluate more reliable biomarkers for improving the predictive utility of the dominant populations of recurrent cervical cancer (RCC) to receive immunotherapy. Methods: Peripheral blood samples of PD-L1 positive patients with RCC treated with second-line PD-1 monoclonal antibody were collected prior to treatment initiation and after the treatment. Differentially expressed genes (DEGs) were analyzed between partial response (PR) patient and progressive disease (PD) patients. Overall design: Peripheral blood samples of PD-L1 positive patients with RCC treated with second-line PD-1 monoclonal antibody were collected prior to treatment initiation and after the treatment. Differentially expressed genes (DEGs) were analyzed between partial response (PR) patient and progressive disease (PD) patients.
