LINC00472 and nonpapillary renal cell carcinoma: Table 1 showed that the expression of Linc00472 was decreased in ccRCC tissues (P < 0.0001). We divided 22 patients into the high-expression group and the low-expression group according to the median expression level of cancer tissues of 22 patients. The statistical results show that the expression level of Linc00472 has no significant correlation with patient gender (P=1.000), age (P=0.387), and tumor size (P=0.395), and the expression level of Linc00472 in grade I and II cancer tissues was significantly higher than that in grade III and IV cancer tissues (P=0.024).
