DCLK1 and nonpapillary renal cell carcinoma: Furthermore, the ccRCC subpopulation with high levels of both PLOD2 and DCLK1-L (PLOD2 high DCLK1-Lhigh group) showed the worst DFS, compared to improved DFS in the PLOD2 high DCLK1-Llow group and the best DFS in the PLOD2 low DCLK1-L low group (Fig. 7H).
