To establish a prognostication scoring system for predicting the ccRCC overall patient survival rate, Cox regression analyses using RNASEH2A, CDK1, and the mean of ITGB1, ITGB4, and PLEC expressions as variables were performed on TCGA KIRC total RNAseq data (tumor sample n = 533, with or without their normal counterparts). The gene discussed is CDK1; the disease is neoplasm.
