CYTOR and nonpapillary renal cell carcinoma: CYTOR exhibited significant expression levels in the high-risk group, as depicted in Figure 9B. Furthermore, there is a positive correlation between the advanced tumor stage and grade, and an elevated risk score, as depicted in Figure 9C and D. In order to evaluate the predictive significance of CYTOR in ccRCC, a Kaplan–Meier analysis was conducted to compare patients with low and high levels of CYTOR expression.
