CCNT2 and renal cell carcinoma: By Lasso analysis and Cox univariate and multivariate analysis, finally, a 9-lncRNA signature, including, KIAA2012, CCNT2-AS1, ITPKB-AS1, TBX2-AS1, NUTM2A-AS1, LINC02522, LINC02384, LINC01559, and LINC00865, was constructed with the potential to predict the prognosis for patients with high stage and grade of RCC.
