Abstract:

AbstractObjectiveTo explore the pyroptosis-related genesPRGsthat are closely related to the prognosis of hepatocellular carcinomaHCC), and construct a corresponding prognostic risk model to evaluate the survival and prognosis of HCC patients. MethodsThe transcriptome data and clinical data of HCC were downloaded from TCGA databaseand the differentially expressed PRGs were screened out. COX analysis was used to determine the PRGs related to the prognosis of HCC and construct a prognostic risk score modelwhile K-M survival curvereceiver operator characteristic curveROC curveand nomogram were plotted to analyze and verify the accuracy of the model and its prognostic value. Results58 differentially expressed PRGs were screened. GO function enrichment analysis showed that these genes were involved in pyroptosisand KEGG signal pathway analysis showed that these genes were mainly enriched in non-alcohdic fatty liver disease and Toll-like receptor signal pathways. Eight PRGs significantly related to the prognosis of HCC were identified by COX analysisand a prognostic risk score model was constructed. ROC curve showed that the area under the curve value of this risk score was 0.802which was higher than other clinical data and could be as an independent prognostic factor. ConclusionThe prognostic risk model constructed by 8 PRGs can effectively predict the prognosis of patients with HCC.
